Coverage is the 2019–2021 Chevrolet Silverado 1500. It plugs in line with the factory connector named in the instructions, using factory-style plugs on both ends, so nothing is cut or spliced.\u003c\/p\u003e\u003cp\u003eIt does not delete the feature. Turning stop-start back on is the same button press as before, and the module will remember that too.

Any trim in these years with factory stop-start and the pictured connector is covered.\u003c\/p\u003e\u003ch2\u003eHow Auto Stop\/Start behaves from the factory\u003c\/h2\u003e\u003cp\u003eThe factory logic arms Auto Stop\/Start every time the engine starts. Turning it off with the button only lasts until the engine is shut down. Owners who sit in stop-and-go traffic, tow, or idle in drive-throughs often prefer it off, and that is where the repeated button press comes from.\u003c\/p\u003e\u003ch2\u003eIf stop-start is not engaging\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\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 full-size pickup, 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\u003eInstallation and removal\u003c\/h2\u003e\u003cp\u003eIt plugs in line with the factory connector named in the instructions, using factory-style plugs on both ends, 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\u003eKeep the battery healthy\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. A wrong or unregistered battery can leave the stop-start system disabled, and that has nothing to do with this module.\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. Switch the ignition off, reseat both ends until the locks click, and test again. If the light stays on, remove the module and confirm the vehicle is fault-free on its own before contacting support.\u003c\/p\u003e\u003ch2\u003eScope of the module\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\u003eFitment check\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eModel year and model match a row in the table above (2019–2021 Chevrolet Silverado 1500).\u003c\/li\u003e\n\u003cli\u003eYour Chevrolet Silverado 1500 has the factory stop-start button.

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\u003eWhat sits behind the system\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. Battery state is one of the inputs that decides whether the engine may stop. With the module installed the same rules apply, and the same battery type should be used when it is replaced.\u003c\/p\u003e\u003ch2\u003eBefore you plug it in\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003ePark on level ground, shift to Park, switch the ignition off and keep the key or fob away from the vehicle.\u003c\/li\u003e\n\u003cli\u003eRead the included instructions for your model before removing any trim.\u003c\/li\u003e\n\u003cli\u003eLocate the connector named in the instructions and compare it with the plugs on the module.\u003c\/li\u003e\n\u003cli\u003eUse a plastic trim tool where a panel has to be eased out, to avoid marking the dash.\u003c\/li\u003e\n\u003cli\u003ePress each connector until the lock clicks; never force a plug that does not line up.\u003c\/li\u003e\n\u003cli\u003eSecure the module with the supplied tie or tape so it cannot rattle or touch moving parts.\u003c\/li\u003e\n\u003cli\u003eStart the vehicle, set Auto Stop\/Start the way you want it, switch off, restart and confirm the setting held.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eIf something is not right\u003c\/h2\u003e\u003cp\u003e\u003cstrong\u003eMemory does not hold:\u003c\/strong\u003e Re-seat both plugs until the locks click, then repeat the restart test.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003e\"Unavailable\" or flashing indicator:\u003c\/strong\u003e A factory condition (battery charge, cabin temperature, engine temperature) is blocking stop-start.

Check the fitment table on this page against your exact model year.\u003c\/p\u003e\u003ch3\u003eWhy does my Chevrolet Silverado 1500 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\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\u003eDoes my Chevrolet Silverado 1500 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\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\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\u003eDoes the stop-start button still work after installation on the Chevrolet Silverado 1500?\u003c\/h3\u003e\u003cp\u003eYes. The factory button works normally. The module simply stores whatever you chose last.\u003c\/p\u003e\u003ch3\u003eHow does it connect?\u003c\/h3\u003e\u003cp\u003eIt plugs in line with the factory connector named in the instructions, using factory-style plugs on both ends, so nothing is cut or spliced.\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\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\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 it change engine power or fuel trims?\u003c\/h3\u003e\u003cp\u003eNo. It does not reprogram the engine or transmission computers.
