Those engines never deactivate cylinders, so the module has nothing to manage on them. Check your code against both lists before you buy.\u003c\/p\u003e\u003cp\u003eAn engine code that is not listed here does not automatically rule the vehicle out, but send us the VIN first so we can check.\u003c\/p\u003e\u003ch2\u003eHow Active Fuel Management operates\u003c\/h2\u003e\u003cp\u003eOn AFM V8 engines, the computer shuts off fuel and holds the valves closed on cylinders 1, 7, 6 and 4 when the load is light, so the engine runs as a V4. It does this through special collapsible lifters on those cylinders, fed by oil-pressure solenoids. When you ask for more power, the lifters lock again and all eight cylinders fire. GM describes this behavior in its service bulletin on AFM and DFM operation.\u003c\/p\u003e\u003cp\u003eGM's 4.3L V6 (RPO LV3) uses the same idea on two cylinders: cylinders 3 and 6 are deactivated at light load, so the engine runs on four. On V8s, AFM drops cylinders 1, 7, 6 and 4. In both cases oil-pressure solenoids switch special lifters into a collapsed state and fuel to those cylinders is cut.\u003c\/p\u003e\u003cp\u003eFor the 2019 redesign of the Silverado 1500 and Sierra 1500, GM introduced Dynamic Fuel Management on the 5.3L L84 and 6.2L L87, which can run on 17 different cylinder patterns. That is a different system from the AFM covered by this listing.\u003c\/p\u003e\u003ch2\u003eThe first drive\u003c\/h2\u003e\u003cp\u003eExpect steadier behavior at part throttle and no change at wide-open throttle. Towing and hill climbing were already mostly done on all cylinders, so the biggest change is during relaxed cruising. Average fuel economy may drop slightly depending on how much of your driving is light-load highway time.\u003c\/p\u003e\u003ch2\u003eCheck the engine first\u003c\/h2\u003e\u003cp\u003eScan for stored codes before you plug it in. Misfire codes on the deactivation cylinders, an AFM solenoid circuit code, or a lifter noise are signs of an existing problem that should be repaired first. The module is meant for a healthy engine where you simply do not want cylinder deactivation.\u003c\/p\u003e\u003ch2\u003eHow this differs from an AFM delete kit\u003c\/h2\u003e\u003cp\u003eThere are three common ways to stop cylinder deactivation on GM engines: a plug-in module like this one, a custom tune that turns AFM off in the engine computer, or a mechanical delete that replaces the AFM lifters and related hardware and then needs a tune to match. The module is the only one of the three that needs no tools and no engine-computer changes, and it is the only one you can undo by unplugging it. It does not replace failed lifters; if hardware is already damaged, the repair comes first.\u003c\/p\u003e\u003ch2\u003eLiving with it\u003c\/h2\u003e\u003cp\u003eLeave it in the port for everyday driving. When the vehicle goes in for service or an emissions check, remove it so the shop has normal access to the diagnostic connector, then reinstall it.\u003c\/p\u003e\u003ch2\u003eWhy owners disable it\u003c\/h2\u003e\u003cp\u003eMany drivers would rather have predictable response than the small economy gain from running on fewer cylinders, especially when towing, hauling or driving in hills. Keeping AFM off removes the mode changes entirely. It does not add horsepower, and it is not a fix for an engine that already has lifter or oil-consumption problems.\u003c\/p\u003e\u003ch2\u003eOil and maintenance\u003c\/h2\u003e\u003cp\u003eAFM lifters and the solenoids that control them run on engine oil pressure. Keeping the oil at the right level, using the grade GM specifies on the oil filler cap or in the owner's manual, and changing it on schedule matters whether or not AFM is active. The module changes when cylinders deactivate; it does not change the oiling system.\u003c\/p\u003e\u003ch2\u003eHow to confirm your engine code\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eYour model year, model and engine match a row in the table (2007–2018 Chevrolet Silverado 1500).\u003c\/li\u003e\n\u003cli\u003eThe quickest checks are the 8th digit of your VIN, which identifies the engine, and the RPO list on the Service Parts Identification label (glovebox or trunk on most pre-2018 GM models, QR code on the driver-door pillar label from 2018).\u003c\/li\u003e\n\u003cli\u003eNo check-engine light is on, and oil level and pressure are normal.\u003c\/li\u003e\n\u003cli\u003eIf the vehicle has an engine swap, an aftermarket tune or a replacement engine computer, contact support first.\u003c\/li\u003e\n\u003cli\u003eQuestions: support@automotivebypass.com with your VIN.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eYear-by-year fitment\u003c\/h2\u003e\u003cp\u003eEach model year from the fitment data, with the AFM engine codes GM used for that year and displacement:\u003c\/p\u003e\u003ctable\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eYear\u003c\/th\u003e\n\u003cth\u003eMake\u003c\/th\u003e\n\u003cth\u003eModel\u003c\/th\u003e\n\u003cth\u003eEngine\u003c\/th\u003e\n\u003cth\u003eAFM codes\u003c\/th\u003e\n\u003cth\u003eListing note\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003e2007\u003c\/td\u003e\n\u003ctd\u003eChevrolet\u003c\/td\u003e\n\u003ctd\u003eSilverado 1500\u003c\/td\u003e\n\u003ctd\u003e5.3L V8 \/ 6.0L V8\u003c\/td\u003e\n\u003ctd\u003eLY5, LC9, LMG, L76\u003c\/td\u003e\n\u003ctd\u003e100% Fitment Match | OEM-Grade Quality | Plug \u0026amp;

Its solenoids send pressurized oil to special hydraulic roller lifters (supplied by Eaton and Delphi) on the deactivating cylinders, which then stop opening the valves. Because the system runs on oil pressure, oil quality matters: worn-out anti-foam additives, the wrong viscosity or overdue changes can delay the oil signal and upset the switching. The module stops the switching; the oil system still needs proper care.\u003c\/p\u003e\u003ch2\u003eWhere AFM came from\u003c\/h2\u003e\u003cp\u003eGM's first attempt was the 1981 Cadillac V8-6-4. Displacement on Demand followed in the 2005 model year on the 5.3L TrailBlazer EXT and Envoy XL\/XUV and on LS4-powered front-drive cars, and was renamed Active Fuel Management as it moved into the full-size trucks and SUVs. Dynamic Fuel Management, developed from Tula Technology's Dynamic Skip Fire, took over on the 2019 Silverado 1500 and Sierra 1500 V8s.\u003c\/p\u003e\u003ch2\u003eCommon questions\u003c\/h2\u003e\u003ch3\u003eCan I go back to factory AFM?\u003c\/h3\u003e\u003cp\u003eYes.

AFM lifters and their solenoids are oil-pressure operated, so an engine that is low on oil or running the wrong grade should be sorted out first. The module stops the switching, but it is not a substitute for maintenance or for repairing an engine that already has a fault.\u003c\/p\u003e\u003ch2\u003eKeep up with oil changes\u003c\/h2\u003e\u003cp\u003eAFM lifters and the solenoids that control them run on engine oil pressure. Keeping the oil at the right level, using the grade GM specifies on the oil filler cap or in the owner's manual, and changing it on schedule matters whether or not AFM is active. The module changes when cylinders deactivate; it does not change the oiling system.\u003c\/p\u003e\u003ch2\u003eWhat owners are after\u003c\/h2\u003e\u003cp\u003eA Chevrolet Equinox Sport with AFM switches modes many times on a typical drive. Some owners never notice; others feel it every time. If you are in the second group, or you tow and want steady behavior, keeping all cylinders active is the simplest answer. Fuel use at light cruise will usually rise a little, since that is where AFM saves fuel.\u003c\/p\u003e\u003ch2\u003eModule, tune or delete kit\u003c\/h2\u003e\u003cp\u003eThere are three common ways to stop cylinder deactivation on GM engines: a plug-in module like this one, a custom tune that turns AFM off in the engine computer, or a mechanical delete that replaces the AFM lifters and related hardware and then needs a tune to match. The module is the only one of the three that needs no tools and no engine-computer changes, and it is the only one you can undo by unplugging it. It does not replace failed lifters; if hardware is already damaged, the repair comes first.\u003c\/p\u003e\u003ch2\u003eAfter installation\u003c\/h2\u003e\u003cp\u003eExpect steadier behavior at part throttle and no change at wide-open throttle.

The earlier LFX (used, for example, in the 2015–2016 Colorado and Canyon) and the LFY in the 2018 Traverse and Enclave have no cylinder deactivation, so the module has nothing to control on them.

Cylinders 1, 7, 6 and 4 have two-stage lifters that the engine computer can switch with oil pressure; once switched, those valves stay shut and the injectors stop firing. The switch back to eight cylinders happens whenever more torque is needed.\u003c\/p\u003e\u003ch2\u003eWhy people turn AFM off\u003c\/h2\u003e\u003cp\u003eOwners usually disable AFM for one of three reasons: they notice the change between modes as a vibration or exhaust drone, they want a consistent throttle response while towing or climbing grades, or they want to limit how often the deactivation lifters switch. Keeping the engine on all cylinders addresses all three. The tradeoff is that you give up whatever fuel saving AFM was providing in light cruising.\u003c\/p\u003e\u003ch2\u003eHow this differs from an AFM delete kit\u003c\/h2\u003e\u003cp\u003eA mechanical AFM delete swaps the deactivating lifters (and often the camshaft and lifter oil manifold) for non-AFM parts and requires a tune afterwards. A tune alone can switch AFM off in software. This module works through the OBD-II port instead, so the engine hardware and its calibration stay stock. That makes it the easiest option to reverse, and the right one only when the engine is mechanically healthy.\u003c\/p\u003e\u003ch2\u003eAfter installation\u003c\/h2\u003e\u003cp\u003eExpect steadier behavior at part throttle and no change at wide-open throttle. Towing and hill climbing were already mostly done on all cylinders, so the biggest change is during relaxed cruising. Average fuel economy may drop slightly depending on how much of your driving is light-load highway time.\u003c\/p\u003e\u003ch2\u003ePractical notes\u003c\/h2\u003e\u003cp\u003eLeave it in the port for everyday driving.

AFM lifters and their solenoids are oil-pressure operated, so an engine that is low on oil or running the wrong grade should be sorted out first. The module stops the switching, but it is not a substitute for maintenance or for repairing an engine that already has a fault.\u003c\/p\u003e\u003ch2\u003eOil and maintenance\u003c\/h2\u003e\u003cp\u003eOil level and quality are worth watching on any AFM engine, because the deactivation hardware is hydraulic. Check the dipstick at fuel stops on high-mileage engines, follow GM's specified oil grade, and address oil-pressure warnings immediately.

Cylinders 1, 7, 6 and 4 have two-stage lifters that the engine computer can switch with oil pressure; once switched, those valves stay shut and the injectors stop firing. The switch back to eight cylinders happens whenever more torque is needed.\u003c\/p\u003e\u003cp\u003eGM replaced AFM with Dynamic Fuel Management (DFM) on the 5.3L L84 and 6.2L L87 starting with the 2019 Silverado 1500 and Sierra 1500.

Keeping AFM off removes the mode changes entirely. It does not add horsepower, and it is not a fix for an engine that already has lifter or oil-consumption problems.\u003c\/p\u003e\u003ch2\u003eLiving with it\u003c\/h2\u003e\u003cp\u003eBecause it occupies the OBD-II port, unplug the module before connecting a scan tool, an insurance logger or an emissions-test probe, then plug it back in afterwards. Make sure it sits clear of your left knee and the pedals, and that the housing is fully seated in the port.\u003c\/p\u003e\u003ch2\u003eMaintenance still matters\u003c\/h2\u003e\u003cp\u003eOil level and quality are worth watching on any AFM engine, because the deactivation hardware is hydraulic. Check the dipstick at fuel stops on high-mileage engines, follow GM's specified oil grade, and address oil-pressure warnings immediately. None of that changes with the module installed.\u003c\/p\u003e\u003ch2\u003eWhat to expect on the road\u003c\/h2\u003e\u003cp\u003eDrive at a steady cruise on a light throttle, where AFM used to switch modes. The engine should now stay on all cylinders, so the subtle shudder, drone or hesitation that came with each change should be gone. If your dash shows instant fuel economy, expect the light-cruise numbers to read a little lower than before, since that is exactly where cylinder deactivation saved fuel.\u003c\/p\u003e\u003ch2\u003eDiagnose existing problems first\u003c\/h2\u003e\u003cp\u003eThis module prevents mode switching. It does not repair anything. If the engine already has a ticking lifter, misfire codes, low oil pressure or high oil consumption, have it diagnosed before relying on the module. Those symptoms need a mechanical repair, and keeping AFM off will not reverse damage that has already happened.\u003c\/p\u003e\u003ch2\u003eModule, tune or delete kit\u003c\/h2\u003e\u003cp\u003eThere are three common ways to stop cylinder deactivation on GM engines: a plug-in module like this one, a custom tune that turns AFM off in the engine computer, or a mechanical delete that replaces the AFM lifters and related hardware and then needs a tune to match. The module is the only one of the three that needs no tools and no engine-computer changes, and it is the only one you can undo by unplugging it. It does not replace failed lifters; if hardware is already damaged, the repair comes first.\u003c\/p\u003e\u003ch2\u003eHow to confirm your engine code\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eYour model year, model and engine match a row in the table (2007–2018 Chevrolet Tahoe).\u003c\/li\u003e\n\u003cli\u003eThe quickest checks are the 8th digit of your VIN, which identifies the engine, and the RPO list on the Service Parts Identification label (glovebox or trunk on most pre-2018 GM models, QR code on the driver-door pillar label from 2018).\u003c\/li\u003e\n\u003cli\u003eThe engine runs cleanly with no stored misfire or AFM codes.\u003c\/li\u003e\n\u003cli\u003eIf the vehicle has an engine swap, an aftermarket tune or a replacement engine computer, contact support first.\u003c\/li\u003e\n\u003cli\u003eQuestions: support@automotivebypass.com with your VIN.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eFitment table with engine codes\u003c\/h2\u003e\u003cp\u003eThe full fitment data, by year, alongside matching AFM engine codes:\u003c\/p\u003e\u003ctable\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eYear\u003c\/th\u003e\n\u003cth\u003eMake\u003c\/th\u003e\n\u003cth\u003eModel\u003c\/th\u003e\n\u003cth\u003eEngine\u003c\/th\u003e\n\u003cth\u003eAFM codes\u003c\/th\u003e\n\u003cth\u003eListing note\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003e2007\u003c\/td\u003e\n\u003ctd\u003eChevrolet\u003c\/td\u003e\n\u003ctd\u003eTahoe\u003c\/td\u003e\n\u003ctd\u003e5.3L V8 \/ 6.0L V8\u003c\/td\u003e\n\u003ctd\u003eLY5, LC9, LMG, L76\u003c\/td\u003e\n\u003ctd\u003e100% Fitment Match | OEM-Grade Quality | Plug \u0026amp;

Its solenoids send pressurized oil to special hydraulic roller lifters (supplied by Eaton and Delphi) on the deactivating cylinders, which then stop opening the valves. Because the system runs on oil pressure, oil quality matters: worn-out anti-foam additives, the wrong viscosity or overdue changes can delay the oil signal and upset the switching. The module stops the switching; the oil system still needs proper care.\u003c\/p\u003e\u003ch2\u003eModel background\u003c\/h2\u003e\u003cp\u003eGM's full-size trucks and SUVs from the 2007 model year rode on the GMT900 platform with Gen IV V8s. The 2014 Silverado 1500 and Sierra 1500, and the 2015 Tahoe, Suburban, Yukon and Escalade, moved to the K2XX platform with the EcoTec3 engines (4.3L LV3, 5.3L L83, 6.2L L86). Both generations used AFM on most gasoline V8s, so the engine code decides fitment more reliably than the model name.\u003c\/p\u003e\u003ch2\u003eA short history of GM cylinder deactivation\u003c\/h2\u003e\u003cp\u003eCylinder deactivation at GM goes back to the 1981 Cadillac V8-6-4. The current approach began as Displacement on Demand, announced in 2003 for the 2005 TrailBlazer EXT, Envoy XL and Envoy XUV 5.3L, then the front-drive 5.3L LS4 cars. Under the Active Fuel Management name it became common on Gen IV and EcoTec3 truck V8s. The 2010 Camaro SS automatic got it on the L99.

Cylinders 1, 7, 6 and 4 have two-stage lifters that the engine computer can switch with oil pressure; once switched, those valves stay shut and the injectors stop firing. The switch back to eight cylinders happens whenever more torque is needed.\u003c\/p\u003e\u003ch2\u003ePractical notes\u003c\/h2\u003e\u003cp\u003eBecause it occupies the OBD-II port, unplug the module before connecting a scan tool, an insurance logger or an emissions-test probe, then plug it back in afterwards.

Check the dipstick at fuel stops on high-mileage engines, follow GM's specified oil grade, and address oil-pressure warnings immediately. None of that changes with the module installed.\u003c\/p\u003e\u003ch2\u003ePlug-in module vs. a mechanical AFM delete\u003c\/h2\u003e\u003cp\u003eOwners who want AFM gone for good sometimes go the mechanical route: non-AFM lifters, a matching camshaft and a retune. That is a large job and it is permanent. A tuner can also disable AFM in the engine computer. The plug-in module sits at the other end of the scale: no parts replaced, no software rewritten, and back to factory with one pull. It is meant for engines that run well and simply should not switch modes.\u003c\/p\u003e\u003ch2\u003eWhat to expect on the road\u003c\/h2\u003e\u003cp\u003eDrive at a steady cruise on a light throttle, where AFM used to switch modes. The engine should now stay on all cylinders, so the subtle shudder, drone or hesitation that came with each change should be gone. If your dash shows instant fuel economy, expect the light-cruise numbers to read a little lower than before, since that is exactly where cylinder deactivation saved fuel.\u003c\/p\u003e\u003ch2\u003eCheck the engine first\u003c\/h2\u003e\u003cp\u003eKeep the oil at the correct level and grade before and after installation. AFM lifters and their solenoids are oil-pressure operated, so an engine that is low on oil or running the wrong grade should be sorted out first. The module stops the switching, but it is not a substitute for maintenance or for repairing an engine that already has a fault.\u003c\/p\u003e\u003ch2\u003eWhy people turn AFM off\u003c\/h2\u003e\u003cp\u003eMany drivers would rather have predictable response than the small economy gain from running on fewer cylinders, especially when towing, hauling or driving in hills.

Cylinders 1, 7, 6 and 4 have two-stage lifters that the engine computer can switch with oil pressure; once switched, those valves stay shut and the injectors stop firing.

Those are the moments when AFM used to drop cylinders. With the module in, engine behavior there should feel the same as under heavier throttle. Full-throttle performance does not change, because AFM was never active at full throttle anyway.\u003c\/p\u003e\u003ch2\u003eIf the engine already has symptoms\u003c\/h2\u003e\u003cp\u003eKeep the oil at the correct level and grade before and after installation. AFM lifters and their solenoids are oil-pressure operated, so an engine that is low on oil or running the wrong grade should be sorted out first. The module stops the switching, but it is not a substitute for maintenance or for repairing an engine that already has a fault.\u003c\/p\u003e\u003ch2\u003eReasons to keep all cylinders running\u003c\/h2\u003e\u003cp\u003eThe usual complaints are a drone or shudder in reduced-cylinder mode, a slight hesitation when the engine switches back, and a general wish to keep the valvetrain doing the same thing all the time. With the module installed, the engine stays in full-cylinder mode, so those transitions stop.

The module is the only one of the three that needs no tools and no engine-computer changes, and it is the only one you can undo by unplugging it.

Solenoids route oil pressure to the lifters on those cylinders, which collapse and stop opening the valves. Fuel to those cylinders is cut at the same time. Press the throttle harder and the system brings all eight back.\u003c\/p\u003e\u003ch2\u003eAfter installation\u003c\/h2\u003e\u003cp\u003eThe difference shows up in light-load driving: steady highway speeds, gentle acceleration and coasting down small grades. Those are the moments when AFM used to drop cylinders. With the module in, engine behavior there should feel the same as under heavier throttle. Full-throttle performance does not change, because AFM was never active at full throttle anyway.\u003c\/p\u003e\u003ch2\u003eIf the engine already has symptoms\u003c\/h2\u003e\u003cp\u003eScan for stored codes before you plug it in.

Keeping the oil at the right level, using the grade GM specifies on the oil filler cap or in the owner's manual, and changing it on schedule matters whether or not AFM is active. The module changes when cylinders deactivate; it does not change the oiling system.\u003c\/p\u003e\u003ch2\u003eWhy people turn AFM off\u003c\/h2\u003e\u003cp\u003eThe usual complaints are a drone or shudder in reduced-cylinder mode, a slight hesitation when the engine switches back, and a general wish to keep the valvetrain doing the same thing all the time. With the module installed, the engine stays in full-cylinder mode, so those transitions stop. Expect light-load fuel economy to be closer to an engine without AFM.\u003c\/p\u003e\u003ch2\u003eLiving with it\u003c\/h2\u003e\u003cp\u003eBecause it occupies the OBD-II port, unplug the module before connecting a scan tool, an insurance logger or an emissions-test probe, then plug it back in afterwards.

The 8th character of the VIN also identifies the engine.\u003c\/li\u003e\n\u003cli\u003eThe engine runs cleanly with no stored misfire or AFM codes.\u003c\/li\u003e\n\u003cli\u003eEngine swaps, custom tunes and replaced ECUs need a fitment check from support before ordering.\u003c\/li\u003e\n\u003cli\u003eQuestions: support@automotivebypass.com with your VIN.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eFitment table with engine codes\u003c\/h2\u003e\u003cp\u003eEach model year from the fitment data, with the AFM engine codes GM used for that year and displacement:\u003c\/p\u003e\u003ctable\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eYear\u003c\/th\u003e\n\u003cth\u003eMake\u003c\/th\u003e\n\u003cth\u003eModel\u003c\/th\u003e\n\u003cth\u003eEngine\u003c\/th\u003e\n\u003cth\u003eAFM codes\u003c\/th\u003e\n\u003cth\u003eListing note\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003e2005\u003c\/td\u003e\n\u003ctd\u003eChevrolet\u003c\/td\u003e\n\u003ctd\u003eTrailblazer\u003c\/td\u003e\n\u003ctd\u003e5.3L V8\u003c\/td\u003e\n\u003ctd\u003eLH6\u003c\/td\u003e\n\u003ctd\u003e100% Fitment Match | OEM-Grade Quality | Plug \u0026amp; Play\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e2006\u003c\/td\u003e\n\u003ctd\u003eChevrolet\u003c\/td\u003e\n\u003ctd\u003eTrailblazer\u003c\/td\u003e\n\u003ctd\u003e5.3L V8\u003c\/td\u003e\n\u003ctd\u003eLH6\u003c\/td\u003e\n\u003ctd\u003e100% Fitment Match | OEM-Grade Quality | Plug \u0026amp; Play\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e2007\u003c\/td\u003e\n\u003ctd\u003eChevrolet\u003c\/td\u003e\n\u003ctd\u003eTrailblazer\u003c\/td\u003e\n\u003ctd\u003e5.3L V8\u003c\/td\u003e\n\u003ctd\u003eLH6\u003c\/td\u003e\n\u003ctd\u003e100% Fitment Match | OEM-Grade Quality | Plug \u0026amp; Play\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e2008\u003c\/td\u003e\n\u003ctd\u003eChevrolet\u003c\/td\u003e\n\u003ctd\u003eTrailblazer\u003c\/td\u003e\n\u003ctd\u003e5.3L V8\u003c\/td\u003e\n\u003ctd\u003eLH6\u003c\/td\u003e\n\u003ctd\u003e100% Fitment Match | OEM-Grade Quality | Plug \u0026amp; Play\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e2009\u003c\/td\u003e\n\u003ctd\u003eChevrolet\u003c\/td\u003e\n\u003ctd\u003eTrailblazer\u003c\/td\u003e\n\u003ctd\u003e5.3L V8\u003c\/td\u003e\n\u003ctd\u003eLH6\u003c\/td\u003e\n\u003ctd\u003e100% Fitment Match | OEM-Grade Quality | Plug \u0026amp; Play\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\u003ch2\u003eLH6 background\u003c\/h2\u003e\u003cp\u003eBesides the TrailBlazer and Envoy, the LH6 went into the Buick Rainier, Saab 9-7X and Isuzu Ascender, and into some 2007–2009 Silverado 1500 and Sierra 1500 pickups.

Solenoids route oil pressure to the lifters on those cylinders, which collapse and stop opening the valves. Fuel to those cylinders is cut at the same time. Press the throttle harder and the system brings all eight back.\u003c\/p\u003e\u003cp\u003eGM's 4.3L V6 (RPO LV3) uses the same idea on two cylinders: cylinders 3 and 6 are deactivated at light load, so the engine runs on four. On V8s, AFM drops cylinders 1, 7, 6 and 4. In both cases oil-pressure solenoids switch special lifters into a collapsed state and fuel to those cylinders is cut.\u003c\/p\u003e\u003cp\u003eGM replaced AFM with Dynamic Fuel Management (DFM) on the 5.3L L84 and 6.2L L87 starting with the 2019 Silverado 1500 and Sierra 1500.

The module is the only one of the three that needs no tools and no engine-computer changes, and it is the only one you can undo by unplugging it. It does not replace failed lifters; if hardware is already damaged, the repair comes first.\u003c\/p\u003e\u003ch2\u003eWhat owners are after\u003c\/h2\u003e\u003cp\u003eA Chevrolet Suburban with AFM switches modes many times on a typical drive. Some owners never notice; others feel it every time. If you are in the second group, or you tow and want steady behavior, keeping all cylinders active is the simplest answer. Fuel use at light cruise will usually rise a little, since that is where AFM saves fuel.\u003c\/p\u003e\u003ch2\u003eWhat to expect on the road\u003c\/h2\u003e\u003cp\u003eThe difference shows up in light-load driving: steady highway speeds, gentle acceleration and coasting down small grades. Those are the moments when AFM used to drop cylinders. With the module in, engine behavior there should feel the same as under heavier throttle. Full-throttle performance does not change, because AFM was never active at full throttle anyway.\u003c\/p\u003e\u003ch2\u003eMaintenance still matters\u003c\/h2\u003e\u003cp\u003eOil level and quality are worth watching on any AFM engine, because the deactivation hardware is hydraulic.

Solenoids route oil pressure to the lifters on those cylinders, which collapse and stop opening the valves. Fuel to those cylinders is cut at the same time. Press the throttle harder and the system brings all eight back.\u003c\/p\u003e\u003ch2\u003ePlug-in module vs. a mechanical AFM delete\u003c\/h2\u003e\u003cp\u003eThere are three common ways to stop cylinder deactivation on GM engines: a plug-in module like this one, a custom tune that turns AFM off in the engine computer, or a mechanical delete that replaces the AFM lifters and related hardware and then needs a tune to match. The module is the only one of the three that needs no tools and no engine-computer changes, and it is the only one you can undo by unplugging it. It does not replace failed lifters; if hardware is already damaged, the repair comes first.\u003c\/p\u003e\u003ch2\u003eWhat to expect on the road\u003c\/h2\u003e\u003cp\u003eThe difference shows up in light-load driving: steady highway speeds, gentle acceleration and coasting down small grades. Those are the moments when AFM used to drop cylinders. With the module in, engine behavior there should feel the same as under heavier throttle. Full-throttle performance does not change, because AFM was never active at full throttle anyway.\u003c\/p\u003e\u003ch2\u003eMaintenance still matters\u003c\/h2\u003e\u003cp\u003eAFM lifters and the solenoids that control them run on engine oil pressure. Keeping the oil at the right level, using the grade GM specifies on the oil filler cap or in the owner's manual, and changing it on schedule matters whether or not AFM is active. The module changes when cylinders deactivate; it does not change the oiling system.\u003c\/p\u003e\u003ch2\u003eWhy people turn AFM off\u003c\/h2\u003e\u003cp\u003eThe usual complaints are a drone or shudder in reduced-cylinder mode, a slight hesitation when the engine switches back, and a general wish to keep the valvetrain doing the same thing all the time. With the module installed, the engine stays in full-cylinder mode, so those transitions stop. Expect light-load fuel economy to be closer to an engine without AFM.\u003c\/p\u003e\u003ch2\u003eLiving with it\u003c\/h2\u003e\u003cp\u003eLeave it in the port for everyday driving. When the vehicle goes in for service or an emissions check, remove it so the shop has normal access to the diagnostic connector, then reinstall it.\u003c\/p\u003e\u003ch2\u003eCheck the engine first\u003c\/h2\u003e\u003cp\u003eThis module prevents mode switching.

That is a large job and it is permanent. A tuner can also disable AFM in the engine computer. The plug-in module sits at the other end of the scale: no parts replaced, no software rewritten, and back to factory with one pull.

The earlier LFX (used, for example, in the 2015–2016 Colorado and Canyon) and the LFY in the 2018 Traverse and Enclave have no cylinder deactivation, so the module has nothing to control on them.

Its solenoids send pressurized oil to special hydraulic roller lifters (supplied by Eaton and Delphi) on the deactivating cylinders, which then stop opening the valves. Because the system runs on oil pressure, oil quality matters: worn-out anti-foam additives, the wrong viscosity or overdue changes can delay the oil signal and upset the switching. The module stops the switching; the oil system still needs proper care.\u003c\/p\u003e\u003ch2\u003eOil and transmission on the LGZ\u003c\/h2\u003e\u003cp\u003eOn the 2017-on Colorado and Canyon, the 3.6L LGZ is paired with the Hydra-Matic 8L45 eight-speed automatic. GM TechLink notes that the engine uses a dual-pressure, variable-displacement vane oil pump inside the oil pan and calls for dexos1 5W-30 oil.

The switch back to eight cylinders happens whenever more torque is needed.\u003c\/p\u003e\u003ch2\u003eWhy owners disable it\u003c\/h2\u003e\u003cp\u003eA Chevrolet Camaro with AFM switches modes many times on a typical drive. Some owners never notice; others feel it every time. If you are in the second group, or you tow and want steady behavior, keeping all cylinders active is the simplest answer. Fuel use at light cruise will usually rise a little, since that is where AFM saves fuel.\u003c\/p\u003e\u003ch2\u003eAfter installation\u003c\/h2\u003e\u003cp\u003eExpect steadier behavior at part throttle and no change at wide-open throttle. Towing and hill climbing were already mostly done on all cylinders, so the biggest change is during relaxed cruising. Average fuel economy may drop slightly depending on how much of your driving is light-load highway time.\u003c\/p\u003e\u003ch2\u003eCheck the engine first\u003c\/h2\u003e\u003cp\u003eKeep the oil at the correct level and grade before and after installation. AFM lifters and their solenoids are oil-pressure operated, so an engine that is low on oil or running the wrong grade should be sorted out first. The module stops the switching, but it is not a substitute for maintenance or for repairing an engine that already has a fault.\u003c\/p\u003e\u003ch2\u003eKeep up with oil changes\u003c\/h2\u003e\u003cp\u003eAFM lifters and the solenoids that control them run on engine oil pressure. Keeping the oil at the right level, using the grade GM specifies on the oil filler cap or in the owner's manual, and changing it on schedule matters whether or not AFM is active. The module changes when cylinders deactivate; it does not change the oiling system.\u003c\/p\u003e\u003ch2\u003eScan tools and inspections\u003c\/h2\u003e\u003cp\u003eLeave it in the port for everyday driving.

The module is the only one of the three that needs no tools and no engine-computer changes, and it is the only one you can undo by unplugging it.

Unplug it and AFM works again as it did from the factory.\u003c\/p\u003e\u003ch2\u003eWhat it fits\u003c\/h2\u003e\u003cp\u003eThe fitment table for this part (all rows marked 100% fitment match):\u003c\/p\u003e\u003cul\u003e\u003cli\u003e2011–2019 Chevrolet Caprice PPV: 6.0L V8\u003c\/li\u003e\u003c\/ul\u003e\u003cp\u003eGM engine codes with AFM that line up with these years and displacements:\u003c\/p\u003e\u003cul\u003e\u003cli\u003eL77 (6.0L, 2011–2017, VIN 8th digit \"2\")\u003c\/li\u003e\u003c\/ul\u003e\u003cp\u003eAn engine code that is not listed here does not automatically rule the vehicle out, but send us the VIN first so we can check.\u003c\/p\u003e\u003ch2\u003eWhat AFM does on these engines\u003c\/h2\u003e\u003cp\u003eOn AFM V8 engines, the computer shuts off fuel and holds the valves closed on cylinders 1, 7, 6 and 4 when the load is light, so the engine runs as a V4. It does this through special collapsible lifters on those cylinders, fed by oil-pressure solenoids. When you ask for more power, the lifters lock again and all eight cylinders fire. GM describes this behavior in its service bulletin on AFM and DFM operation.\u003c\/p\u003e\u003ch2\u003ePractical notes\u003c\/h2\u003e\u003cp\u003eBecause it occupies the OBD-II port, unplug the module before connecting a scan tool, an insurance logger or an emissions-test probe, then plug it back in afterwards. Make sure it sits clear of your left knee and the pedals, and that the housing is fully seated in the port.\u003c\/p\u003e\u003ch2\u003eWhat to expect on the road\u003c\/h2\u003e\u003cp\u003eDrive at a steady cruise on a light throttle, where AFM used to switch modes. The engine should now stay on all cylinders, so the subtle shudder, drone or hesitation that came with each change should be gone. If your dash shows instant fuel economy, expect the light-cruise numbers to read a little lower than before, since that is exactly where cylinder deactivation saved fuel.\u003c\/p\u003e\u003ch2\u003eWhy owners disable it\u003c\/h2\u003e\u003cp\u003eThe usual complaints are a drone or shudder in reduced-cylinder mode, a slight hesitation when the engine switches back, and a general wish to keep the valvetrain doing the same thing all the time. With the module installed, the engine stays in full-cylinder mode, so those transitions stop. Expect light-load fuel economy to be closer to an engine without AFM.\u003c\/p\u003e\u003ch2\u003ePlug-in module vs. a mechanical AFM delete\u003c\/h2\u003e\u003cp\u003eThere are three common ways to stop cylinder deactivation on GM engines: a plug-in module like this one, a custom tune that turns AFM off in the engine computer, or a mechanical delete that replaces the AFM lifters and related hardware and then needs a tune to match. The module is the only one of the three that needs no tools and no engine-computer changes, and it is the only one you can undo by unplugging it. It does not replace failed lifters; if hardware is already damaged, the repair comes first.\u003c\/p\u003e\u003ch2\u003eDiagnose existing problems first\u003c\/h2\u003e\u003cp\u003eScan for stored codes before you plug it in. Misfire codes on the deactivation cylinders, an AFM solenoid circuit code, or a lifter noise are signs of an existing problem that should be repaired first. The module is meant for a healthy engine where you simply do not want cylinder deactivation.\u003c\/p\u003e\u003ch2\u003eMaintenance still matters\u003c\/h2\u003e\u003cp\u003eOil level and quality are worth watching on any AFM engine, because the deactivation hardware is hydraulic. Check the dipstick at fuel stops on high-mileage engines, follow GM's specified oil grade, and address oil-pressure warnings immediately.

Cylinders 1, 7, 6 and 4 have two-stage lifters that the engine computer can switch with oil pressure; once switched, those valves stay shut and the injectors stop firing. The switch back to eight cylinders happens whenever more torque is needed.\u003c\/p\u003e\u003ch2\u003eUsing it day to day\u003c\/h2\u003e\u003cp\u003eThe module uses the OBD-II port, so it has to come out whenever a technician or an inspection station needs the port. Plugging it back in restores the all-cylinder mode. Route it so the driver cannot kick it loose.\u003c\/p\u003e\u003ch2\u003eReasons to keep all cylinders running\u003c\/h2\u003e\u003cp\u003eOwners usually disable AFM for one of three reasons: they notice the change between modes as a vibration or exhaust drone, they want a consistent throttle response while towing or climbing grades, or they want to limit how often the deactivation lifters switch. Keeping the engine on all cylinders addresses all three. The tradeoff is that you give up whatever fuel saving AFM was providing in light cruising.\u003c\/p\u003e\u003ch2\u003eCheck the engine first\u003c\/h2\u003e\u003cp\u003eKeep the oil at the correct level and grade before and after installation. AFM lifters and their solenoids are oil-pressure operated, so an engine that is low on oil or running the wrong grade should be sorted out first. The module stops the switching, but it is not a substitute for maintenance or for repairing an engine that already has a fault.\u003c\/p\u003e\u003ch2\u003eWhat to expect on the road\u003c\/h2\u003e\u003cp\u003eExpect steadier behavior at part throttle and no change at wide-open throttle. Towing and hill climbing were already mostly done on all cylinders, so the biggest change is during relaxed cruising. Average fuel economy may drop slightly depending on how much of your driving is light-load highway time.\u003c\/p\u003e\u003ch2\u003eModule, tune or delete kit\u003c\/h2\u003e\u003cp\u003eThere are three common ways to stop cylinder deactivation on GM engines: a plug-in module like this one, a custom tune that turns AFM off in the engine computer, or a mechanical delete that replaces the AFM lifters and related hardware and then needs a tune to match. The module is the only one of the three that needs no tools and no engine-computer changes, and it is the only one you can undo by unplugging it. It does not replace failed lifters; if hardware is already damaged, the repair comes first.\u003c\/p\u003e\u003ch2\u003eEngine care\u003c\/h2\u003e\u003cp\u003eDisabling cylinder deactivation does not replace normal maintenance. Use the oil grade and change interval GM lists for your engine, watch the oil level between changes, and repair leaks promptly.

For the 2019 Silverado, GM introduced Dynamic Fuel Management, based on Tula Technology's Dynamic Skip Fire, which can deactivate cylinders individually.\u003c\/p\u003e\u003ch2\u003eEngine data at a glance\u003c\/h2\u003e\u003cp\u003eRatings and features for the engine codes that apply to this listing, as published for each engine (figures vary by vehicle and year):\u003c\/p\u003e\u003ctable\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eRPO code\u003c\/th\u003e\n\u003cth\u003eSize\u003c\/th\u003e\n\u003cth\u003ePower\u003c\/th\u003e\n\u003cth\u003eTorque\u003c\/th\u003e\n\u003cth\u003eCompression\u003c\/th\u003e\n\u003cth\u003eNotes\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eLY5\u003c\/td\u003e\n\u003ctd\u003e5.3L\u003c\/td\u003e\n\u003ctd\u003e315–320 hp\u003c\/td\u003e\n\u003ctd\u003e335–340 lb-ft\u003c\/td\u003e\n\u003ctd\u003e9.95:1\u003c\/td\u003e\n\u003ctd\u003eiron block, AFM\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLC9\u003c\/td\u003e\n\u003ctd\u003e5.3L\u003c\/td\u003e\n\u003ctd\u003e315–320 hp\u003c\/td\u003e\n\u003ctd\u003e335 lb-ft\u003c\/td\u003e\n\u003ctd\u003e9.60:1 or 9.95:1\u003c\/td\u003e\n\u003ctd\u003ealuminum block, AFM, E85-capable\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLMG\u003c\/td\u003e\n\u003ctd\u003e5.3L\u003c\/td\u003e\n\u003ctd\u003e315–320 hp\u003c\/td\u003e\n\u003ctd\u003e335–340 lb-ft\u003c\/td\u003e\n\u003ctd\u003e9.60:1\u003c\/td\u003e\n\u003ctd\u003eAFM, E85-capable\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eL76\u003c\/td\u003e\n\u003ctd\u003e6.0L\u003c\/td\u003e\n\u003ctd\u003e348–367 hp\u003c\/td\u003e\n\u003ctd\u003e376–385 lb-ft\u003c\/td\u003e\n\u003ctd\u003e10.40:1\u003c\/td\u003e\n\u003ctd\u003ealuminum block, AFM, VVT on truck versions\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLFA\u003c\/td\u003e\n\u003ctd\u003e6.0L\u003c\/td\u003e\n\u003ctd\u003e332 hp\u003c\/td\u003e\n\u003ctd\u003e367 lb-ft\u003c\/td\u003e\n\u003ctd\u003e10.80:1\u003c\/td\u003e\n\u003ctd\u003ealuminum block, AFM, hybrid\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\u003ch2\u003eThe 6.2L V8 story: L92, L9H and L94\u003c\/h2\u003e\u003cp\u003eNot every GMT900 6.2L has cylinder deactivation.

That is a large job and it is permanent. A tuner can also disable AFM in the engine computer. The plug-in module sits at the other end of the scale: no parts replaced, no software rewritten, and back to factory with one pull. It is meant for engines that run well and simply should not switch modes.\u003c\/p\u003e\u003ch2\u003eKeep up with oil changes\u003c\/h2\u003e\u003cp\u003eDisabling cylinder deactivation does not replace normal maintenance.

The engine should now stay on all cylinders, so the subtle shudder, drone or hesitation that came with each change should be gone.

Stop-start vehicles usually run an AGM or EFB battery, and the system is one of the first features to drop out as that battery ages. Cabin temperature requests, engine temperature and brake pressure also factor in. None of these checks are altered by the module.\u003c\/p\u003e\u003ch2\u003eBattery and charging\u003c\/h2\u003e\u003cp\u003eVehicles with stop-start normally use an AGM or EFB battery sized for repeated restarts.

Under EPA test rules, a system that stays off after shutdown is tested both on and off and the results are averaged, which lowers the rated fuel economy, so most systems reset at every key cycle.

Scan the vehicle for stored codes, test the battery and confirm the system works normally with the factory button before installation. That baseline makes any later issue easy to pin down.\u003c\/p\u003e\u003ch2\u003eTypical reasons to keep it off\u003c\/h2\u003e\u003cp\u003eSome owners only want stop-start off in certain seasons or on certain trips, such as towing a trailer or crawling through summer traffic with the A\/C working hard. Because the module remembers whatever you chose last, it works both ways: leave the system off for a week, then switch it back on with the factory button and it stays on.\u003c\/p\u003e\u003ch2\u003eBattery and charging\u003c\/h2\u003e\u003cp\u003eVehicles with stop-start normally use an AGM or EFB battery sized for repeated restarts. If you replace it, use the same type and size, and follow the manufacturer's battery reset or registration step where one exists.

When the battery ages, the system quietly stops auto-stopping long before the battery fails to crank.

Those checks stay in control after this module is installed. It does not force stops and it does not bypass any of those safety inputs.\u003c\/p\u003e\u003ch2\u003eDay-to-day use\u003c\/h2\u003e\u003cp\u003eStop-start saves the most fuel in long idles, but plenty of drivers would rather keep the engine running. Common reasons: towing or hauling, where an engine restart under load is unwelcome; drive-thru lines and parking lots, where the engine cycles on and off every few feet; hot days, when the A\/C compressor stops with the engine on many vehicles; and stop-and-go traffic where the restart delay is noticeable when pulling into a gap.

If a stop-start system is non-latching, meaning it switches back on whenever the vehicle is restarted, the EPA measures fuel economy with the system working. If the driver can switch it off permanently, the EPA tests with it both on and off and averages the two, which gives a lower number. Manufacturers therefore make the system come back on at every start, and drivers who prefer it off end up pressing the button each trip.\u003c\/p\u003e\u003ch2\u003eIf something is not right\u003c\/h2\u003e\u003cp\u003e\u003cstrong\u003eChoice is forgotten after restart:\u003c\/strong\u003e A plug is usually not fully home.

A restart at every stop is noticeable in a compact crossover, the climate system may run at reduced output while the engine is off, and quick moves into traffic feel slower when the engine has to fire first. If those are your reasons, you probably press the button on every drive now. With the module, you press it once.\u003c\/p\u003e\u003ch2\u003eThings that already block an auto stop\u003c\/h2\u003e\u003cp\u003eEven with Auto Stop\/Start enabled, the engine control logic only stops the engine when conditions allow it. Typical blockers are a low battery state of charge, an engine that has not reached operating temperature, heavy heating or A\/C demand, steering input, an open door or unlatched seatbelt, and some drive modes. If the system never seems to stop the engine, one of these is usually the reason, and the module does not change that logic.\u003c\/p\u003e\u003ch2\u003eDiagnostics first\u003c\/h2\u003e\u003cp\u003eA warning light that appears after installation usually means a connector is not fully seated.

If a stop-start system is non-latching, meaning it switches back on whenever the vehicle is restarted, the EPA measures fuel economy with the system working. If the driver can switch it off permanently, the EPA tests with it both on and off and averages the two, which gives a lower number.

The factory button works normally. The module simply stores whatever you chose last.\u003c\/p\u003e\u003ch3\u003eWhy does Auto Stop\/Start turn itself back on every time?\u003c\/h3\u003e\u003cp\u003eAutomakers set stop-start to default to on at each start. Under EPA test rules, a system that stays off after shutdown is tested both on and off and the results are averaged, which lowers the rated fuel economy, so most systems reset at every key cycle. The module carries your last choice across that reset.\u003c\/p\u003e\u003ch3\u003eDoes it change how the battery is charged?\u003c\/h3\u003e\u003cp\u003eNo. Charging is still managed by the vehicle. Stop-start vehicles normally use an AGM or EFB battery built for frequent restarts; replace it with the same type when it wears out.\u003c\/p\u003e\u003ch3\u003eIs this the same part for every Chevrolet?\u003c\/h3\u003e\u003cp\u003eNo. Connectors and the module that holds the stop-start state differ by platform, so this SKU is matched to the fitment rows on this page.

The listing is written around the tenth-generation (2014-2020) Impala. Trim levels are not split out in the table, so confirm that your vehicle has the stop-start button before ordering.\u003c\/p\u003e\u003ch2\u003eWhat the factory system does\u003c\/h2\u003e\u003cp\u003eEach start of the Chevrolet Impala begins with Auto Stop\/Start enabled. The switch on the dash can disable it, but only until the key is cycled. This module records the switch position and repeats it after the restart, which is the entire job it does.\u003c\/p\u003e\u003ch2\u003eBattery and charging\u003c\/h2\u003e\u003cp\u003eIf the stop-start indicator shows the system as unavailable, test the battery before anything else. On stop-start vehicles that is the most common cause. A replacement should match the original specification (AGM or EFB), and some manufacturers call for a battery monitor reset after the swap.\u003c\/p\u003e\u003ch2\u003eWhen the engine will not auto-stop anyway\u003c\/h2\u003e\u003cp\u003eAuto stop needs several conditions at once: a warm engine, enough battery charge, moderate cabin heating or cooling demand, and the vehicle fully stopped with the brake held. If any is missing, the engine keeps running. The module only remembers the button state; the factory controller still decides whether a stop is allowed.\u003c\/p\u003e\u003ch2\u003eInstalling the inline memory harness\u003c\/h2\u003e\u003cp\u003eIt plugs in line with the factory connector named in the instructions. Both ends are factory-style plugs, so nothing is cut or spliced. The instructions show the connector for this application; compare it with the product photos before starting. Turn the vehicle off, make the connection, fix the module in place, and test with two or three key cycles.\u003c\/p\u003e\u003ch2\u003eIf something does not look right\u003c\/h2\u003e\u003cp\u003eIf a \"stop-start unavailable\" or similar message appears, check the battery first. A battery that tests weak, a recent battery replacement that was not registered where the manufacturer requires it, or a fault in the battery current sensor can all disable the system. Clear up those issues before judging how the module works, because it cannot hold a setting the vehicle refuses to accept.\u003c\/p\u003e\u003ch2\u003eTypical reasons to keep it off\u003c\/h2\u003e\u003cp\u003eStop-start saves the most fuel in long idles, but plenty of drivers would rather keep the engine running. Common reasons: towing or hauling, where an engine restart under load is unwelcome; drive-thru lines and parking lots, where the engine cycles on and off every few feet; hot days, when the A\/C compressor stops with the engine on many vehicles; and stop-and-go traffic where the restart delay is noticeable when pulling into a gap. On a full-size sedan, any of these can mean a button press at the start of nearly every drive.\u003c\/p\u003e\u003ch2\u003eWhat changes after installation\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eNo tune, no reflash, no change to horsepower or shift points.\u003c\/li\u003e\n\u003cli\u003eKeeps the original switch fully functional.\u003c\/li\u003e\n\u003cli\u003eStores the stop-start choice you made last and repeats it at the next start.\u003c\/li\u003e\n\u003cli\u003eFully reversible: unplug it and the vehicle returns to factory behavior.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eQuick fitment check\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eModel year and model match a row in the table above (2016–2018 Chevrolet Impala).\u003c\/li\u003e\n\u003cli\u003eYour Chevrolet Impala has the factory stop-start button.

If a sensor goes quiet (dead battery, damaged sensor, or wheels without sensors), the system sets a fault. Federal standard FMVSS No. 138 requires this kind of warning on light vehicles built from September 1, 2007: a steady telltale when a tire is 25% or more below the placard pressure, and a malfunction indication that flashes for about a minute and then stays on when the system cannot work properly.\u003c\/p\u003e\u003ch2\u003eResponsible use\u003c\/h2\u003e\u003cp\u003eA TPMS emulator removes your low-pressure warning, so manual checks have to take its place: cold pressure readings from the placard, a monthly check at minimum, and a look at tread and sidewalls.

The rule sets a low-pressure warning at 25% below the placard pressure, within 20 minutes of driving, and a separate malfunction signal: about a minute of flashing at start-up followed by a steady light. A missing sensor signal counts as a malfunction.\u003c\/p\u003e\u003ch2\u003eWhen the sensor wheels go back on (GM)\u003c\/h2\u003e\u003cp\u003eWhen the original sensor wheels go back on, GM owner's manuals describe a sensor matching process.

Then activate each sensor with a TPMS relearn tool held against the sidewall near the valve stem, in order: driver front, passenger front, passenger rear, driver rear. A chirp confirms each one.

Mount wheels without sensors and those IDs stop transmitting, so the system reports a fault.

Check all four tires (and the spare) with a gauge at least once a month and before long trips, using the cold pressures on the door-jamb placard, and look for nails, cuts and bulges while you are there. Federal law also bars dealers and repair businesses from knowingly disabling required safety equipment, and state inspection rules differ, so check what applies to your vehicle and use before running it on the road.\u003c\/p\u003e\u003ch2\u003eDiagnosis first\u003c\/h2\u003e\u003cp\u003eA light that will not clear usually means a mismatch: a different year or receiver version than the listing, or a setup step that did not complete.

Mount wheels without sensors and those IDs stop transmitting, so the system reports a fault. Under FMVSS No. 138, that fault shows as a TPMS light that flashes for roughly a minute at start-up and then stays lit, repeating on every start until the system sees its sensors again.\u003c\/p\u003e\u003ch2\u003eSeasonal wheel swaps\u003c\/h2\u003e\u003cp\u003eWhen you go back to the original sensor-equipped wheels, remove or disconnect the emulator as the instructions describe and let the vehicle recognize its sensors again. If the original sensors were rotated or replaced, the vehicle may need its normal TPMS relearn. Store the sensor wheels indoors and keep the valve caps on to keep moisture out of the valve stems.\u003c\/p\u003e\u003ch2\u003eTroubleshooting\u003c\/h2\u003e\u003cp\u003eIf the TPMS light remains on after setup, confirm the part matches your exact year and model, then follow the setup steps in the instructions again. A warning that persists can also point to a receiver or body-module fault, damaged wiring, or a different TPMS configuration than the one listed. The emulator cannot repair those, so a scan of the vehicle for stored codes is the next step.\u003c\/p\u003e\u003ch2\u003eChecking pressure the right way\u003c\/h2\u003e\u003cp\u003eWithout TPMS warnings, a monthly routine does the job: tires cold, gauge on each valve, compare with the door-jamb placard, top up as needed, and look over the tread and sidewalls.

Phase-in started in October 2005, and all new US light vehicles up to 10,000 lb GVWR built from September 1, 2007 must have TPMS. The rule sets a low-pressure warning at 25% below the placard pressure, within 20 minutes of driving, and a separate malfunction signal: about a minute of flashing at start-up followed by a steady light. A missing sensor signal counts as a malfunction.\u003c\/p\u003e\u003ch2\u003eHow these vehicles monitor pressure\u003c\/h2\u003e\u003cp\u003eThere are two ways to monitor tire pressure. Indirect systems use the ABS wheel-speed sensors and look for a tire turning faster because it is underinflated. Direct systems, like the one on the Chevrolet Cruze and Chevrolet Cruze Limited, put a battery-powered sensor in each wheel, usually on the valve stem, and transmit actual pressure. Because a direct system expects to hear each sensor, wheels without sensors cause a fault, which is the situation the emulator addresses.\u003c\/p\u003e\u003ch2\u003eFAQ\u003c\/h2\u003e\u003ch3\u003eWhich Chevrolet Cruze and Chevrolet Cruze Limited years does this TPMS emulator fit?\u003c\/h3\u003e\u003cp\u003eThe fitment table lists Chevrolet Cruze 2011–2016; Chevrolet Cruze Limited 2016.

If a sensor goes quiet (dead battery, damaged sensor, or wheels without sensors), the system sets a fault. Federal standard FMVSS No. 138 requires this kind of warning on light vehicles built from September 1, 2007: a steady telltale when a tire is 25% or more below the placard pressure, and a malfunction indication that flashes for about a minute and then stays on when the system cannot work properly.\u003c\/p\u003e\u003ch2\u003eWhen the original wheels go back on\u003c\/h2\u003e\u003cp\u003eWhen you go back to the original sensor-equipped wheels, remove or disconnect the emulator as the instructions describe and let the vehicle recognize its sensors again. If the original sensors were rotated or replaced, the vehicle may need its normal TPMS relearn. Store the sensor wheels indoors and keep the valve caps on to keep moisture out of the valve stems.\u003c\/p\u003e\u003ch2\u003eSafety and legal notes\u003c\/h2\u003e\u003cp\u003eWith the emulator in place, the dashboard will not tell you about a leak. Check all four tires (and the spare) with a gauge at least once a month and before long trips, using the cold pressures on the door-jamb placard, and look for nails, cuts and bulges while you are there. Federal law also bars dealers and repair businesses from knowingly disabling required safety equipment, and state inspection rules differ, so check what applies to your vehicle and use before running it on the road.\u003c\/p\u003e\u003ch2\u003eTypical uses\u003c\/h2\u003e\u003cp\u003eMost buyers have wheels without sensors that they use part of the year, such as a winter set, a track set or a show set.

Indirect systems use the ABS wheel-speed sensors and look for a tire turning faster because it is underinflated. Direct systems, like the one on the Chevrolet Express 1500 and Chevrolet Express 2500, put a battery-powered sensor in each wheel, usually on the valve stem, and transmit actual pressure. Because a direct system expects to hear each sensor, wheels without sensors cause a fault, which is the situation the emulator addresses.\u003c\/p\u003e\u003ch2\u003eBackground: the TPMS standard\u003c\/h2\u003e\u003cp\u003eAfter the TREAD Act of 2000, NHTSA issued FMVSS No. 138. It was phased in from October 2005 and applies to every new light vehicle (10,000 lb GVWR or less) built from September 1, 2007. The system must warn within 20 minutes of driving when a tire is 25% or more below the placard cold pressure, and it must also show a malfunction: the TPMS light flashes for about 60 to 90 seconds at start-up and then stays on. Wheels without sensors trigger that malfunction warning.\u003c\/p\u003e\u003ch2\u003eFAQ\u003c\/h2\u003e\u003ch3\u003eWhich Chevrolet Express 1500 and Chevrolet Express 2500 years does this TPMS emulator fit?\u003c\/h3\u003e\u003cp\u003eThe fitment table lists Chevrolet Express 1500 2008–2011; Chevrolet Express 2500 2008–2011.

Mount wheels without sensors and those IDs stop transmitting, so the system reports a fault. Under FMVSS No. 138, that fault shows as a TPMS light that flashes for roughly a minute at start-up and then stays lit, repeating on every start until the system sees its sensors again.\u003c\/p\u003e\u003ch2\u003eChecking pressure yourself\u003c\/h2\u003e\u003cp\u003eA TPMS emulator removes your low-pressure warning, so manual checks have to take its place: cold pressure readings from the placard, a monthly check at minimum, and a look at tread and sidewalls. Inspection and road-use rules for TPMS vary by state, and federal law limits what shops may disable. Confirm the rules for your situation before use.\u003c\/p\u003e\u003ch2\u003eSeasonal wheel swaps\u003c\/h2\u003e\u003cp\u003eWhen you go back to the original sensor-equipped wheels, remove or disconnect the emulator as the instructions describe and let the vehicle recognize its sensors again. If the original sensors were rotated or replaced, the vehicle may need its normal TPMS relearn. Store the sensor wheels indoors and keep the valve caps on to keep moisture out of the valve stems.\u003c\/p\u003e\u003ch2\u003eChecking pressure the right way\u003c\/h2\u003e\u003cp\u003eUse the cold inflation pressure printed on the tire placard on the driver-side door jamb, not the maximum figure molded into the tire sidewall. \"Cold\" means the vehicle has been parked for about three hours or driven only a short distance. Check every tire including the spare, add air in small steps, and recheck. Doing this monthly covers most of what the TPMS warning would have told you.\u003c\/p\u003e\u003ch2\u003eTroubleshooting\u003c\/h2\u003e\u003cp\u003eBefore installation, make sure the TPMS system works on the original wheels.

Indirect systems, used by some other makers, rely on ABS wheel-speed data instead. Direct systems are the ones that complain when sensors are missing, which is why an emulator is needed on sensorless wheels.\u003c\/p\u003e\u003ch2\u003eWhat FMVSS No. 138 requires\u003c\/h2\u003e\u003cp\u003eAfter the TREAD Act of 2000, NHTSA issued FMVSS No. 138. It was phased in from October 2005 and applies to every new light vehicle (10,000 lb GVWR or less) built from September 1, 2007. The system must warn within 20 minutes of driving when a tire is 25% or more below the placard cold pressure, and it must also show a malfunction: the TPMS light flashes for about 60 to 90 seconds at start-up and then stays on. Wheels without sensors trigger that malfunction warning.\u003c\/p\u003e\u003ch2\u003eTroubleshooting\u003c\/h2\u003e\u003cp\u003e\u003cstrong\u003eStill lit after setup:\u003c\/strong\u003e Check fitment and repeat the steps in order.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIt was lit before:\u003c\/strong\u003e Repair the existing TPMS fault first.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eBack on original wheels and lit:\u003c\/strong\u003e Use the vehicle's normal relearn procedure.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eNot sure what is happening:\u003c\/strong\u003e Email support with your VIN.\u003c\/p\u003e\u003ch2\u003eRe-learning the original sensors (GM)\u003c\/h2\u003e\u003cp\u003eGM's documented relearn is quick once you have a TPMS tool. Set the parking brake, switch the ignition on without starting the engine and put the receiver in learn mode (LOCK plus UNLOCK on the fob for roughly five seconds, or the tire-pressure item in the DIC menu) until the horn chirps twice. Trigger the sensors in the order driver front, passenger front, passenger rear, driver rear; each answers with a chirp, and the last with two.

When the wheels on the vehicle have no sensors, the dash shows a TPMS fault. This emulator for the 2008–2010, 2013–2016 Chevrolet Malibu and 2016 Chevrolet Malibu Limited provides those signals so the warning stays off.

If a sensor goes quiet (dead battery, damaged sensor, or wheels without sensors), the system sets a fault. Federal standard FMVSS No. 138 requires this kind of warning on light vehicles built from September 1, 2007: a steady telltale when a tire is 25% or more below the placard pressure, and a malfunction indication that flashes for about a minute and then stays on when the system cannot work properly.\u003c\/p\u003e\u003ch2\u003eUsing the placard pressure\u003c\/h2\u003e\u003cp\u003eUse the cold inflation pressure printed on the tire placard on the driver-side door jamb, not the maximum figure molded into the tire sidewall. \"Cold\" means the vehicle has been parked for about three hours or driven only a short distance. Check every tire including the spare, add air in small steps, and recheck. Doing this monthly covers most of what the TPMS warning would have told you.\u003c\/p\u003e\u003ch2\u003eTypical uses\u003c\/h2\u003e\u003cp\u003eThe usual situation is a second wheel set: dedicated winter wheels, track wheels or off-road wheels that were never fitted with sensors. Buying and programming a second set of sensors costs money and time, and without them the TPMS light stays on all season. An emulator covers that set while the original wheels and sensors sit in storage.\u003c\/p\u003e\u003ch2\u003eChecking pressure yourself\u003c\/h2\u003e\u003cp\u003eA TPMS emulator removes your low-pressure warning, so manual checks have to take its place: cold pressure readings from the placard, a monthly check at minimum, and a look at tread and sidewalls. Inspection and road-use rules for TPMS vary by state, and federal law limits what shops may disable. Confirm the rules for your situation before use.\u003c\/p\u003e\u003ch2\u003eTroubleshooting\u003c\/h2\u003e\u003cp\u003eA light that will not clear usually means a mismatch: a different year or receiver version than the listing, or a setup step that did not complete. Re-check the fitment rows and instructions. If they match, scan for codes, because a receiver or module fault will keep the light on regardless of what is installed.\u003c\/p\u003e\u003ch2\u003eSeasonal wheel swaps\u003c\/h2\u003e\u003cp\u003eMost owners switch between two sets of wheels once or twice a year.

It requires a warning when any tire is at least 25% under the recommended cold pressure, delivered within 20 minutes of driving, and a malfunction indication (flashing for roughly 60–90 seconds, then steady) when the system cannot do its job, including when sensors are absent.\u003c\/p\u003e\u003ch2\u003eWhen the sensor wheels go back on (GM)\u003c\/h2\u003e\u003cp\u003eGM's documented relearn is quick once you have a TPMS tool. Set the parking brake, switch the ignition on without starting the engine and put the receiver in learn mode (LOCK plus UNLOCK on the fob for roughly five seconds, or the tire-pressure item in the DIC menu) until the horn chirps twice. Trigger the sensors in the order driver front, passenger front, passenger rear, driver rear; each answers with a chirp, and the last with two. The process stops if the first wheel takes more than two minutes or all four take more than five.\u003c\/p\u003e\u003ch2\u003eFAQ\u003c\/h2\u003e\u003ch3\u003eDoes it measure tire pressure?\u003c\/h3\u003e\u003cp\u003eNo. It supplies the signals the system expects.

It requires a warning when any tire is at least 25% under the recommended cold pressure, delivered within 20 minutes of driving, and a malfunction indication (flashing for roughly 60–90 seconds, then steady) when the system cannot do its job, including when sensors are absent.\u003c\/p\u003e\u003ch2\u003eGM sensor matching after a wheel swap\u003c\/h2\u003e\u003cp\u003eGM's documented relearn is quick once you have a TPMS tool. Set the parking brake, switch the ignition on without starting the engine and put the receiver in learn mode (LOCK plus UNLOCK on the fob for roughly five seconds, or the tire-pressure item in the DIC menu) until the horn chirps twice. Trigger the sensors in the order driver front, passenger front, passenger rear, driver rear; each answers with a chirp, and the last with two.

The required system warns when a tire falls 25% below the recommended cold pressure, and separately flags a malfunction with a flashing-then-steady light. On the Chevrolet, a missing sensor signal is treated as a malfunction, which is the warning this emulator is meant to address.\u003c\/p\u003e\u003ch2\u003eTroubleshooting\u003c\/h2\u003e\u003cp\u003eA light that will not clear usually means a mismatch: a different year or receiver version than the listing, or a setup step that did not complete. Re-check the fitment rows and instructions. If they match, scan for codes, because a receiver or module fault will keep the light on regardless of what is installed.\u003c\/p\u003e\u003ch2\u003eWhen owners use an emulator\u003c\/h2\u003e\u003cp\u003eThe usual situation is a second wheel set: dedicated winter wheels, track wheels or off-road wheels that were never fitted with sensors. Buying and programming a second set of sensors costs money and time, and without them the TPMS light stays on all season. An emulator covers that set while the original wheels and sensors sit in storage.\u003c\/p\u003e\u003ch2\u003eSafety and legal notes\u003c\/h2\u003e\u003cp\u003eWith the emulator in place, the dashboard will not tell you about a leak. Check all four tires (and the spare) with a gauge at least once a month and before long trips, using the cold pressures on the door-jamb placard, and look for nails, cuts and bulges while you are there. Federal law also bars dealers and repair businesses from knowingly disabling required safety equipment, and state inspection rules differ, so check what applies to your vehicle and use before running it on the road.\u003c\/p\u003e\u003ch2\u003eSeasonal wheel swaps\u003c\/h2\u003e\u003cp\u003eMost owners switch between two sets of wheels once or twice a year. Keep the instructions with the emulator so the swap is easy to repeat, and note which wheels were on which corner. If you have the original sensor wheels mounted again and the light stays on, run the vehicle's standard TPMS relearn procedure.\u003c\/p\u003e\u003ch2\u003eChecking pressure the right way\u003c\/h2\u003e\u003cp\u003eWithout TPMS warnings, a monthly routine does the job: tires cold, gauge on each valve, compare with the door-jamb placard, top up as needed, and look over the tread and sidewalls.

Mount wheels without sensors and those IDs stop transmitting, so the system reports a fault. Under FMVSS No. 138, that fault shows as a TPMS light that flashes for roughly a minute at start-up and then stays lit, repeating on every start until the system sees its sensors again.\u003c\/p\u003e\u003ch2\u003eSafety and legal notes\u003c\/h2\u003e\u003cp\u003eTPMS is required safety equipment on new light vehicles in the US under FMVSS No. 138, and 49 U.S.C. 30122 prohibits manufacturers, dealers and repair businesses from knowingly making such equipment inoperative. Requirements for owners and for state inspections vary. Whatever the use, a tire gauge and regular visual checks replace the warning the system would have given you.\u003c\/p\u003e\u003ch2\u003eUsing the placard pressure\u003c\/h2\u003e\u003cp\u003eWithout TPMS warnings, a monthly routine does the job: tires cold, gauge on each valve, compare with the door-jamb placard, top up as needed, and look over the tread and sidewalls.

If the original sensors were rotated or replaced, the vehicle may need its normal TPMS relearn. Store the sensor wheels indoors and keep the valve caps on to keep moisture out of the valve stems.\u003c\/p\u003e\u003ch2\u003eIf the warning stays on\u003c\/h2\u003e\u003cp\u003eBefore installation, make sure the TPMS system works on the original wheels. If it already shows a fault with good sensors fitted, the problem is in the vehicle (receiver, module or wiring), and that needs repair first.

On the Chevrolet Sonic, a missing sensor signal is treated as a malfunction, which is the warning this emulator is meant to address.\u003c\/p\u003e\u003ch2\u003eDiagnosis first\u003c\/h2\u003e\u003cp\u003eA light that will not clear usually means a mismatch: a different year or receiver version than the listing, or a setup step that did not complete. Re-check the fitment rows and instructions. If they match, scan for codes, because a receiver or module fault will keep the light on regardless of what is installed.\u003c\/p\u003e\u003ch2\u003eChecking pressure yourself\u003c\/h2\u003e\u003cp\u003eTPMS is required safety equipment on new light vehicles in the US under FMVSS No. 138, and 49 U.S.C. 30122 prohibits manufacturers, dealers and repair businesses from knowingly making such equipment inoperative. Requirements for owners and for state inspections vary. Whatever the use, a tire gauge and regular visual checks replace the warning the system would have given you.\u003c\/p\u003e\u003ch2\u003eTypical uses\u003c\/h2\u003e\u003cp\u003eIt is aimed at vehicles that spend time on wheels without sensors: off-road builds, track days, winter tires on steel wheels, or show vehicles. On each of those, a permanent TPMS light hides any other warning that might appear in the same spot, which is the main reason owners want it gone.\u003c\/p\u003e\u003ch2\u003eUsing the placard pressure\u003c\/h2\u003e\u003cp\u003eWithout TPMS warnings, a monthly routine does the job: tires cold, gauge on each valve, compare with the door-jamb placard, top up as needed, and look over the tread and sidewalls. Larger off-road or winter tires may call for different pressures than the factory placard; follow the tire maker's guidance in that case.\u003c\/p\u003e\u003ch2\u003eSwitching between wheel sets\u003c\/h2\u003e\u003cp\u003eMost owners switch between two sets of wheels once or twice a year.

If a sensor goes quiet (dead battery, damaged sensor, or wheels without sensors), the system sets a fault. Federal standard FMVSS No. 138 requires this kind of warning on light vehicles built from September 1, 2007: a steady telltale when a tire is 25% or more below the placard pressure, and a malfunction indication that flashes for about a minute and then stays on when the system cannot work properly.\u003c\/p\u003e\u003ch2\u003eDiagnosis first\u003c\/h2\u003e\u003cp\u003eBefore installation, make sure the TPMS system works on the original wheels. If it already shows a fault with good sensors fitted, the problem is in the vehicle (receiver, module or wiring), and that needs repair first. Starting from a working system makes the emulator setup straightforward to check.\u003c\/p\u003e\u003ch2\u003eSafety and legal notes\u003c\/h2\u003e\u003cp\u003eA TPMS emulator removes your low-pressure warning, so manual checks have to take its place: cold pressure readings from the placard, a monthly check at minimum, and a look at tread and sidewalls. Inspection and road-use rules for TPMS vary by state, and federal law limits what shops may disable. Confirm the rules for your situation before use.\u003c\/p\u003e\u003ch2\u003eWhen owners use an emulator\u003c\/h2\u003e\u003cp\u003eThe usual situation is a second wheel set: dedicated winter wheels, track wheels or off-road wheels that were never fitted with sensors. Buying and programming a second set of sensors costs money and time, and without them the TPMS light stays on all season. An emulator covers that set while the original wheels and sensors sit in storage.\u003c\/p\u003e\u003ch2\u003eSeasonal wheel swaps\u003c\/h2\u003e\u003cp\u003eMost owners switch between two sets of wheels once or twice a year.

It requires a warning when any tire is at least 25% under the recommended cold pressure, delivered within 20 minutes of driving, and a malfunction indication (flashing for roughly 60–90 seconds, then steady) when the system cannot do its job, including when sensors are absent.\u003c\/p\u003e\u003ch2\u003eGM sensor matching after a wheel swap\u003c\/h2\u003e\u003cp\u003eWhen the original sensor wheels go back on, GM owner's manuals describe a sensor matching process. With the parking brake set and the ignition on (engine off), hold the key fob LOCK and UNLOCK buttons together for about five seconds, or use the Driver Information Center menu; the horn sounds twice and TIRE LEARNING ACTIVE appears. Then activate each sensor with a TPMS relearn tool held against the sidewall near the valve stem, in order: driver front, passenger front, passenger rear, driver rear. A chirp confirms each one. You have two minutes for the first wheel and five minutes for all four. Finish by setting all tires to the placard pressure.\u003c\/p\u003e\u003ch2\u003eSetup prep checklist\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eStart from a fault-free TPMS on the sensor wheels.\u003c\/li\u003e\n\u003cli\u003eRead your model's instructions.\u003c\/li\u003e\n\u003cli\u003eSet pressures cold to the placard figure.\u003c\/li\u003e\n\u003cli\u003eStore the sensor wheels indoors.\u003c\/li\u003e\n\u003cli\u003eComplete the setup as described.\u003c\/li\u003e\n\u003cli\u003eRestart and look at the TPMS light.\u003c\/li\u003e\n\u003cli\u003ePlan regular gauge checks from now on.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eTwo kinds of TPMS\u003c\/h2\u003e\u003cp\u003eIndirect TPMS works out pressure from wheel speed through the ABS sensors. Direct TPMS, used on the Chevrolet Spark, has a sensor with its own battery inside each wheel and reports measured pressure by radio. The sensor battery is sealed in, so a sensor is replaced when its battery runs down. Remove the sensors and a direct system reports a malfunction.\u003c\/p\u003e\u003ch2\u003eFAQ\u003c\/h2\u003e\u003ch3\u003eDoes it measure tire pressure?\u003c\/h3\u003e\u003cp\u003eNo. It supplies the signals the system expects.

Typical use is a second set of wheels that has no sensors, where the factory system would otherwise keep its warning lit. Because it supplies an expected signal instead of real readings, it cannot warn you about a slow leak.

The required system warns when a tire falls 25% below the recommended cold pressure, and separately flags a malfunction with a flashing-then-steady light. On the Chevrolet Suburban 1500, a missing sensor signal is treated as a malfunction, which is the warning this emulator is meant to address.\u003c\/p\u003e\u003ch2\u003eSwitching between wheel sets\u003c\/h2\u003e\u003cp\u003eMost owners switch between two sets of wheels once or twice a year. Keep the instructions with the emulator so the swap is easy to repeat, and note which wheels were on which corner. If you have the original sensor wheels mounted again and the light stays on, run the vehicle's standard TPMS relearn procedure.\u003c\/p\u003e\u003ch2\u003eUsing the placard pressure\u003c\/h2\u003e\u003cp\u003eUse the cold inflation pressure printed on the tire placard on the driver-side door jamb, not the maximum figure molded into the tire sidewall. \"Cold\" means the vehicle has been parked for about three hours or driven only a short distance. Check every tire including the spare, add air in small steps, and recheck. Doing this monthly covers most of what the TPMS warning would have told you.\u003c\/p\u003e\u003ch2\u003eChecking pressure yourself\u003c\/h2\u003e\u003cp\u003eWith the emulator in place, the dashboard will not tell you about a leak. Check all four tires (and the spare) with a gauge at least once a month and before long trips, using the cold pressures on the door-jamb placard, and look for nails, cuts and bulges while you are there. Federal law also bars dealers and repair businesses from knowingly disabling required safety equipment, and state inspection rules differ, so check what applies to your vehicle and use before running it on the road.\u003c\/p\u003e\u003ch2\u003eWhere it fits in\u003c\/h2\u003e\u003cp\u003eThe usual situation is a second wheel set: dedicated winter wheels, track wheels or off-road wheels that were never fitted with sensors. Buying and programming a second set of sensors costs money and time, and without them the TPMS light stays on all season. An emulator covers that set while the original wheels and sensors sit in storage.\u003c\/p\u003e\u003ch2\u003eDiagnosis first\u003c\/h2\u003e\u003cp\u003eA light that will not clear usually means a mismatch: a different year or receiver version than the listing, or a setup step that did not complete.

Indirect systems use the ABS wheel-speed sensors and look for a tire turning faster because it is underinflated. Direct systems, like the one on the Chevrolet Suburban 1500, put a battery-powered sensor in each wheel, usually on the valve stem, and transmit actual pressure. Because a direct system expects to hear each sensor, wheels without sensors cause a fault, which is the situation the emulator addresses.\u003c\/p\u003e\u003ch2\u003eIf the light stays on\u003c\/h2\u003e\u003cp\u003e\u003cstrong\u003eStill lit after setup:\u003c\/strong\u003e Check fitment and repeat the steps in order.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIt was lit before:\u003c\/strong\u003e Repair the existing TPMS fault first.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eBack on original wheels and lit:\u003c\/strong\u003e Use the vehicle's normal relearn procedure.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eNot sure what is happening:\u003c\/strong\u003e Email support with your VIN.\u003c\/p\u003e\u003ch2\u003eWhat FMVSS No. 138 requires\u003c\/h2\u003e\u003cp\u003eThe TPMS requirement is federal standard FMVSS No. 138, adopted under the TREAD Act of 2000 and fully in force for light vehicles built from September 1, 2007. It requires a warning when any tire is at least 25% under the recommended cold pressure, delivered within 20 minutes of driving, and a malfunction indication (flashing for roughly 60–90 seconds, then steady) when the system cannot do its job, including when sensors are absent.\u003c\/p\u003e\u003ch2\u003eFAQ\u003c\/h2\u003e\u003ch3\u003eIs it legal to use on the road?\u003c\/h3\u003e\u003cp\u003eTPMS is required equipment on new US light vehicles, and rules for owners and inspections vary by state.

The required system warns when a tire falls 25% below the recommended cold pressure, and separately flags a malfunction with a flashing-then-steady light. On the Chevrolet Suburban 2500 and Chevrolet Suburban 3500 HD, a missing sensor signal is treated as a malfunction, which is the warning this emulator is meant to address.\u003c\/p\u003e\u003ch2\u003eTroubleshooting\u003c\/h2\u003e\u003cp\u003eBefore installation, make sure the TPMS system works on the original wheels. If it already shows a fault with good sensors fitted, the problem is in the vehicle (receiver, module or wiring), and that needs repair first. Starting from a working system makes the emulator setup straightforward to check.\u003c\/p\u003e\u003ch2\u003eChecking pressure yourself\u003c\/h2\u003e\u003cp\u003eTPMS is required safety equipment on new light vehicles in the US under FMVSS No. 138, and 49 U.S.C. 30122 prohibits manufacturers, dealers and repair businesses from knowingly making such equipment inoperative. Requirements for owners and for state inspections vary.

If the original sensors were rotated or replaced, the vehicle may need its normal TPMS relearn. Store the sensor wheels indoors and keep the valve caps on to keep moisture out of the valve stems.\u003c\/p\u003e\u003ch2\u003eTypical uses\u003c\/h2\u003e\u003cp\u003eMost buyers have wheels without sensors that they use part of the year, such as a winter set, a track set or a show set. The emulator keeps the dash clear while those wheels are on.

Indirect systems use the ABS wheel-speed sensors and look for a tire turning faster because it is underinflated. Direct systems, like the one on the Chevrolet Suburban 2500 and Chevrolet Suburban 3500 HD, put a battery-powered sensor in each wheel, usually on the valve stem, and transmit actual pressure. Because a direct system expects to hear each sensor, wheels without sensors cause a fault, which is the situation the emulator addresses.\u003c\/p\u003e\u003ch2\u003eAfter-setup checks\u003c\/h2\u003e\u003cp\u003e\u003cstrong\u003eStill lit after setup:\u003c\/strong\u003e Check fitment and repeat the steps in order.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIt was lit before:\u003c\/strong\u003e Repair the existing TPMS fault first.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eBack on original wheels and lit:\u003c\/strong\u003e Use the vehicle's normal relearn procedure.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eNot sure what is happening:\u003c\/strong\u003e Email support with your VIN.\u003c\/p\u003e\u003ch2\u003eBackground: the TPMS standard\u003c\/h2\u003e\u003cp\u003eAfter the TREAD Act of 2000, NHTSA issued FMVSS No. 138. It was phased in from October 2005 and applies to every new light vehicle (10,000 lb GVWR or less) built from September 1, 2007. The system must warn within 20 minutes of driving when a tire is 25% or more below the placard cold pressure, and it must also show a malfunction: the TPMS light flashes for about 60 to 90 seconds at start-up and then stays on. Wheels without sensors trigger that malfunction warning.\u003c\/p\u003e\u003ch2\u003eTerms used on this page\u003c\/h2\u003e\u003cp\u003e\u003cstrong\u003eTPMS:\u003c\/strong\u003e Tire pressure monitoring system.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFMVSS No. 138:\u003c\/strong\u003e The federal safety standard that requires TPMS on new US light vehicles.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eRelearn:\u003c\/strong\u003e The procedure that teaches the vehicle the IDs of its wheel sensors.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDirect TPMS:\u003c\/strong\u003e A system with a pressure sensor in each wheel.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eMalfunction indicator:\u003c\/strong\u003e The TPMS light flashing at start-up and then staying on, signalling a system fault.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003ePlacard pressure:\u003c\/strong\u003e The recommended cold inflation pressure on the driver-side door-jamb label.\u003c\/p\u003e\u003ch2\u003eRe-learning the original sensors (GM)\u003c\/h2\u003e\u003cp\u003eGM's documented relearn is quick once you have a TPMS tool.

Trigger the sensors in the order driver front, passenger front, passenger rear, driver rear; each answers with a chirp, and the last with two.

The required system warns when a tire falls 25% below the recommended cold pressure, and separately flags a malfunction with a flashing-then-steady light. On the Chevrolet Tahoe and Chevrolet Uplander, a missing sensor signal is treated as a malfunction, which is the warning this emulator is meant to address.\u003c\/p\u003e\u003ch2\u003eSeasonal wheel swaps\u003c\/h2\u003e\u003cp\u003eMost owners switch between two sets of wheels once or twice a year. Keep the instructions with the emulator so the swap is easy to repeat, and note which wheels were on which corner. If you have the original sensor wheels mounted again and the light stays on, run the vehicle's standard TPMS relearn procedure.\u003c\/p\u003e\u003ch2\u003eChecking pressure yourself\u003c\/h2\u003e\u003cp\u003eA TPMS emulator removes your low-pressure warning, so manual checks have to take its place: cold pressure readings from the placard, a monthly check at minimum, and a look at tread and sidewalls. Inspection and road-use rules for TPMS vary by state, and federal law limits what shops may disable. Confirm the rules for your situation before use.\u003c\/p\u003e\u003ch2\u003eManual pressure checks\u003c\/h2\u003e\u003cp\u003eThe number that matters is on the door-jamb placard. Measure when the tires are cold (parked for a few hours), because a warm tire reads higher. A pencil gauge is fine; a good digital gauge is easier to read. Write down the readings for a few weeks and a slow leak becomes obvious long before it becomes a flat.\u003c\/p\u003e\u003ch2\u003eTypical uses\u003c\/h2\u003e\u003cp\u003eMost buyers have wheels without sensors that they use part of the year, such as a winter set, a track set or a show set. The emulator keeps the dash clear while those wheels are on. When the original sensor-equipped wheels go back on, the factory system can be returned to normal operation following the instructions.\u003c\/p\u003e\u003ch2\u003eIf the warning stays on\u003c\/h2\u003e\u003cp\u003eBefore installation, make sure the TPMS system works on the original wheels.

It stands in for the factory wheel sensors so the tire-pressure monitoring system sees the signals it expects and the TPMS warning stays off when the wheels on the vehicle do not have working sensors.

Mount wheels without sensors and those IDs stop transmitting, so the system reports a fault. Under FMVSS No. 138, that fault shows as a TPMS light that flashes for roughly a minute at start-up and then stays lit, repeating on every start until the system sees its sensors again.\u003c\/p\u003e\u003ch2\u003eUsing the placard pressure\u003c\/h2\u003e\u003cp\u003eUse the cold inflation pressure printed on the tire placard on the driver-side door jamb, not the maximum figure molded into the tire sidewall. \"Cold\" means the vehicle has been parked for about three hours or driven only a short distance. Check every tire including the spare, add air in small steps, and recheck. Doing this monthly covers most of what the TPMS warning would have told you.\u003c\/p\u003e\u003ch2\u003eResponsible use\u003c\/h2\u003e\u003cp\u003eWith the emulator in place, the dashboard will not tell you about a leak. Check all four tires (and the spare) with a gauge at least once a month and before long trips, using the cold pressures on the door-jamb placard, and look for nails, cuts and bulges while you are there. Federal law also bars dealers and repair businesses from knowingly disabling required safety equipment, and state inspection rules differ, so check what applies to your vehicle and use before running it on the road.\u003c\/p\u003e\u003ch2\u003eWhere it fits in\u003c\/h2\u003e\u003cp\u003eThe usual situation is a second wheel set: dedicated winter wheels, track wheels or off-road wheels that were never fitted with sensors. Buying and programming a second set of sensors costs money and time, and without them the TPMS light stays on all season. An emulator covers that set while the original wheels and sensors sit in storage.\u003c\/p\u003e\u003ch2\u003eSwitching between wheel sets\u003c\/h2\u003e\u003cp\u003eMost owners switch between two sets of wheels once or twice a year. Keep the instructions with the emulator so the swap is easy to repeat, and note which wheels were on which corner. If you have the original sensor wheels mounted again and the light stays on, run the vehicle's standard TPMS relearn procedure.\u003c\/p\u003e\u003ch2\u003eTroubleshooting\u003c\/h2\u003e\u003cp\u003eBefore installation, make sure the TPMS system works on the original wheels.

Indirect systems use the ABS wheel-speed sensors and look for a tire turning faster because it is underinflated. Direct systems, like the one on the Chevrolet Corvette, put a battery-powered sensor in each wheel, usually on the valve stem, and transmit actual pressure. Because a direct system expects to hear each sensor, wheels without sensors cause a fault, which is the situation the emulator addresses.\u003c\/p\u003e\u003ch2\u003eWhen the sensor wheels go back on (GM)\u003c\/h2\u003e\u003cp\u003eGM's documented relearn is quick once you have a TPMS tool. Set the parking brake, switch the ignition on without starting the engine and put the receiver in learn mode (LOCK plus UNLOCK on the fob for roughly five seconds, or the tire-pressure item in the DIC menu) until the horn chirps twice. Trigger the sensors in the order driver front, passenger front, passenger rear, driver rear; each answers with a chirp, and the last with two.

Common reasons: towing or hauling, where an engine restart under load is unwelcome; drive-thru lines and parking lots, where the engine cycles on and off every few feet; hot days, when the A\/C compressor stops with the engine on many vehicles; and stop-and-go traffic where the restart delay is noticeable when pulling into a gap.

The memory module does not change any of that hardware.

You can switch it off with the dash button, but the choice is not saved. The next ignition cycle brings the default back.

Typical blockers are a low battery state of charge, an engine that has not reached operating temperature, heavy heating or A\/C demand, steering input, an open door or unlatched seatbelt, and some drive modes. If the system never seems to stop the engine, one of these is usually the reason, and the module does not change that logic.\u003c\/p\u003e\u003ch2\u003eWhat the module does and does not do\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eIt does not change engine power, transmission shifts, emissions calibration or fuel trims.\u003c\/li\u003e\n\u003cli\u003eIt remembers the last stop-start setting through a key cycle.\u003c\/li\u003e\n\u003cli\u003eIt leaves the factory button working, so you can turn stop-start back on whenever you want.\u003c\/li\u003e\n\u003cli\u003eIt does not write anything to the vehicle's modules, and removing it restores the stock default.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eA note on the battery\u003c\/h2\u003e\u003cp\u003eMost stop-start systems watch battery condition closely through a sensor on the negative terminal. When the battery ages, the system quietly stops auto-stopping long before the battery fails to crank. Keeping the original battery type (AGM or EFB) and a clean, tight ground connection avoids a lot of confusion about why the system behaves differently from week to week.\u003c\/p\u003e\u003ch2\u003eTypical reasons to keep it off\u003c\/h2\u003e\u003cp\u003eDrivers usually switch stop-start off for comfort or habit. A restart at every stop is noticeable in a midsize crossover, the climate system may run at reduced output while the engine is off, and quick moves into traffic feel slower when the engine has to fire first. If those are your reasons, you probably press the button on every drive now. With the module, you press it once.\u003c\/p\u003e\u003ch2\u003eIf something does not look right\u003c\/h2\u003e\u003cp\u003eIf the setting is not remembered, check that the module was installed with the ignition off and that the connector clicked into place.

If the battery is weak, the vehicle will skip automatic stops on its own. The module leaves this hardware and its monitoring alone. Use the factory battery type when replacing it, and check the owner's manual for any battery reset step after replacement.\u003c\/p\u003e\u003ch2\u003eThe reason the button has to be pressed every trip\u003c\/h2\u003e\u003cp\u003eThe factory behavior is tied to how fuel economy is rated in the US. A stop-start system that comes back on at each restart is rated with stop-start active. A system the driver can leave off would be tested both ways and averaged, which lowers the label figure. That is why Auto Stop\/Start on the Chevrolet Blazer resets to on, and why a memory module is the way to keep your own preference.\u003c\/p\u003e\u003ch2\u003eFAQ\u003c\/h2\u003e\u003ch3\u003eDoes the stop-start button still work after installation on the Chevrolet Blazer?\u003c\/h3\u003e\u003cp\u003eYes.

Cabin temperature requests, engine temperature and brake pressure also factor in. None of these checks are altered by the module.\u003c\/p\u003e\u003ch2\u003eKeep the battery healthy\u003c\/h2\u003e\u003cp\u003eIf the stop-start indicator shows the system as unavailable, test the battery before anything else.

Stop-start vehicles normally use an AGM or EFB battery built for frequent restarts; replace it with the same type when it wears out.\u003c\/p\u003e\u003ch3\u003eWhy does Auto Stop\/Start turn itself back on every time?\u003c\/h3\u003e\u003cp\u003eAutomakers set stop-start to default to on at each start. Under EPA test rules, a system that stays off after shutdown is tested both on and off and the results are averaged, which lowers the rated fuel economy, so most systems reset at every key cycle. The module carries your last choice across that reset.\u003c\/p\u003e\u003ch3\u003eDoes it change engine power or fuel trims?\u003c\/h3\u003e\u003cp\u003eNo. It does not reprogram the engine or transmission computers.

The factory button works normally. The module simply stores whatever you chose last.\u003c\/p\u003e\u003ch3\u003eWhy does my Chevrolet Equinox sometimes not auto-stop even when the system is on?\u003c\/h3\u003e\u003cp\u003eThe factory logic checks battery charge, engine temperature, climate load and other inputs.

Under EPA test rules, a system that stays off after shutdown is tested both on and off and the results are averaged, which lowers the rated fuel economy, so most systems reset at every key cycle. The module carries your last choice across that reset.\u003c\/p\u003e\u003ch3\u003eDoes my Chevrolet Traverse need the factory stop-start button for this to work?\u003c\/h3\u003e\u003cp\u003eYes. The module works with the factory stop-start system and its button. A vehicle built without stop-start has no setting for it to remember.\u003c\/p\u003e\u003ch3\u003eWhy does my Chevrolet Traverse sometimes not auto-stop even when the system is on?\u003c\/h3\u003e\u003cp\u003eThe factory logic checks battery charge, engine temperature, climate load and other inputs. If any are outside range it keeps the engine running. The module does not affect those checks.\u003c\/p\u003e\u003ch3\u003eDoes it change how the battery is charged?\u003c\/h3\u003e\u003cp\u003eNo. Charging is still managed by the vehicle. Stop-start vehicles normally use an AGM or EFB battery built for frequent restarts; replace it with the same type when it wears out.\u003c\/p\u003e\u003ch3\u003eWill it fix a \"stop-start unavailable\" message?\u003c\/h3\u003e\u003cp\u003eNo. That message usually points to the battery or a sensor.

A stop-start system that comes back on at each restart is rated with stop-start active. A system the driver can leave off would be tested both ways and averaged, which lowers the label figure. That is why Auto Stop\/Start on the Chevrolet Tahoe resets to on, and why a memory module is the way to keep your own preference.\u003c\/p\u003e\u003ch2\u003eBattery and starter on stop-start vehicles\u003c\/h2\u003e\u003cp\u003eStop-start puts extra load on the battery and starter, so manufacturers fit an AGM or enhanced flooded (EFB) battery and a starter rated for more cycles.

Under EPA test rules, a system that stays off after shutdown is tested both on and off and the results are averaged, which lowers the rated fuel economy, so most systems reset at every key cycle. The module carries your last choice across that reset.\u003c\/p\u003e\u003ch3\u003eDoes the stop-start button still work after installation on the Chevrolet Tahoe?\u003c\/h3\u003e\u003cp\u003eYes.

A restart at every stop is noticeable in a full-size SUV, the climate system may run at reduced output while the engine is off, and quick moves into traffic feel slower when the engine has to fire first.

Stop-start vehicles usually run an AGM or EFB battery, and the system is one of the first features to drop out as that battery ages. Cabin temperature requests, engine temperature and brake pressure also factor in. None of these checks are altered by the module.\u003c\/p\u003e\u003ch2\u003eTroubleshooting notes\u003c\/h2\u003e\u003cp\u003eA dead or weak battery, a charging problem or an unrelated module fault will change how Auto Stop\/Start behaves with or without this part installed. Scan the vehicle for stored codes, test the battery and confirm the system works normally with the factory button before installation. That baseline makes any later issue easy to pin down.\u003c\/p\u003e\u003ch2\u003eKeep the battery healthy\u003c\/h2\u003e\u003cp\u003eVehicles with stop-start normally use an AGM or EFB battery sized for repeated restarts.

A stop-start system that comes back on at each restart is rated with stop-start active. A system the driver can leave off would be tested both ways and averaged, which lowers the label figure. That is why Auto Stop\/Start on the Chevrolet Suburban resets to on, and why a memory module is the way to keep your own preference.\u003c\/p\u003e\u003ch2\u003eTroubleshooting after installation\u003c\/h2\u003e\u003cp\u003e\u003cstrong\u003eSetting not remembered:\u003c\/strong\u003e Check that both connectors are fully latched, then set Auto Stop\/Start the way you want it, switch the vehicle fully off and restart.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eStop-start indicator flashes or shows unavailable:\u003c\/strong\u003e The vehicle is reporting a condition such as low battery charge, high climate demand or a cold engine.

The module repeats your last selection at the next start. If you leave it on, it stays on.\u003c\/p\u003e\u003ch3\u003eWhy does my Chevrolet Suburban sometimes not auto-stop even when the system is on?\u003c\/h3\u003e\u003cp\u003eThe factory logic checks battery charge, engine temperature, climate load and other inputs. If any are outside range it keeps the engine running. The module does not affect those checks.\u003c\/p\u003e\u003ch3\u003eWhich Chevrolet Suburban years does this fit?\u003c\/h3\u003e\u003cp\u003eThe listed range is 2021–2026. Check the fitment table on this page against your exact model year.\u003c\/p\u003e\u003ch3\u003eDoes it change how the battery is charged?\u003c\/h3\u003e\u003cp\u003eNo. Charging is still managed by the vehicle. Stop-start vehicles normally use an AGM or EFB battery built for frequent restarts; replace it with the same type when it wears out.\u003c\/p\u003e\u003ch3\u003eCan I remove it later?\u003c\/h3\u003e\u003cp\u003eYes. Unplug the module and reconnect the factory connector; the vehicle returns to its stock default.\u003c\/p\u003e\u003ch3\u003eWhy does Auto Stop\/Start turn itself back on every time?\u003c\/h3\u003e\u003cp\u003eAutomakers set stop-start to default to on at each start. Under EPA test rules, a system that stays off after shutdown is tested both on and off and the results are averaged, which lowers the rated fuel economy, so most systems reset at every key cycle. The module carries your last choice across that reset.\u003c\/p\u003e\u003ch3\u003eIs this the same part for every Chevrolet?\u003c\/h3\u003e\u003cp\u003eNo. Connectors and the module that holds the stop-start state differ by platform, so this SKU is matched to the fitment rows on this page. Send the VIN to support if you are unsure.\u003c\/p\u003e\u003ch3\u003eWill it fix a \"stop-start unavailable\" message?\u003c\/h3\u003e\u003cp\u003eNo. That message usually points to the battery or a sensor. Diagnose and repair that first.\u003c\/p\u003e\u003ch3\u003eDoes it change engine power or fuel trims?\u003c\/h3\u003e\u003cp\u003eNo. It does not reprogram the engine or transmission computers. It only stores the stop-start button state.\u003c\/p\u003e\u003ch3\u003eDoes my Chevrolet Suburban need the factory stop-start button for this to work?\u003c\/h3\u003e\u003cp\u003eYes. The module works with the factory stop-start system and its button. A vehicle built without stop-start has no setting for it to remember.\u003c\/p\u003e\u003ch3\u003eWhat happens if I unplug it?\u003c\/h3\u003e\u003cp\u003eThe vehicle returns to the factory default, with Auto Stop\/Start switched on at every start.\u003c\/p\u003e\u003ch3\u003eDoes the stop-start button still work after installation on the Chevrolet Suburban?\u003c\/h3\u003e\u003cp\u003eYes.
