Press the button once, and the setting carries over to the next start. 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\u003eYou can still use the original button at any time.

You can switch it off with the dash button, but the choice is not saved. The next ignition cycle brings the default back. The module keeps the choice you made instead.\u003c\/p\u003e\u003ch2\u003eWhy owners turn it off\u003c\/h2\u003e\u003cp\u003ePressing the same button on every drive is what wears on owners. People who tow, plow, idle in pickup lines, creep through heavy traffic or simply want the engine running at a light end up making the same press dozens of times a week. On the Chevrolet Silverado 1500, the module turns that into a one-time choice you can still change whenever you want.\u003c\/p\u003e\u003ch2\u003eIf stop-start is not engaging\u003c\/h2\u003e\u003cp\u003eA Chevrolet Silverado 1500 that rarely auto-stops is often telling you something about the battery. 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 notes for stop-start vehicles\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\u003eScope of the module\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\u003eInstalling the plug-and-play memory harness\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.

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 Silverado 1500 resets to on, and why a memory module is the way to keep your own preference.\u003c\/p\u003e\u003ch2\u003eInstall prep checklist\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eSwitch everything off and take the key or fob out of range.\u003c\/li\u003e\n\u003cli\u003eGo through the model-specific instructions first.\u003c\/li\u003e\n\u003cli\u003eMatch the vehicle connector to the module before unplugging anything.\u003c\/li\u003e\n\u003cli\u003eRelease clips with a trim tool instead of pulling on wires.\u003c\/li\u003e\n\u003cli\u003eListen for the click on each latch.\u003c\/li\u003e\n\u003cli\u003eTie the module down so it stays quiet and away from moving parts.\u003c\/li\u003e\n\u003cli\u003eRun a restart test to confirm the memory works before refitting trim.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eBattery and starter on stop-start vehicles\u003c\/h2\u003e\u003cp\u003eTo cope with repeated restarts, stop-start vehicles normally carry an AGM or EFB battery and a heavier-duty starter, and the system watches battery charge closely. If the battery is weak, the vehicle will skip automatic stops on its own. The module leaves this hardware and its monitoring alone.

If any are outside range it keeps the engine running. The module does not affect those checks.\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\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\u003eWill Auto Stop\/Start come back on when I restart my Chevrolet Silverado 1500?\u003c\/h3\u003e\u003cp\u003eNot if you turned it off before shutting down. The module repeats your last selection at the next start. If you leave it on, it stays on.\u003c\/p\u003e\u003ch3\u003eWhich Chevrolet Silverado 1500 years does this fit?\u003c\/h3\u003e\u003cp\u003eThe listed range is 2019–2021. Check the fitment table on this page against your exact model year.\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\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 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\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\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\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\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\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\u003ch2\u003eWarranty and returns\u003c\/h2\u003e\u003cp\u003eWe ship free within the contiguous United States (1–2 business days to dispatch, roughly 3–4 business days in transit).
