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\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. Removing it returns the vehicle to its original default.\u003c\/p\u003e\u003ch2\u003eVehicles and years covered\u003c\/h2\u003e\u003cp\u003eListed applications (each row is a 100% fitment match for the factory connector this part uses):\u003c\/p\u003e\u003cul\u003e\u003cli\u003eFord F-150: 2018–2020\u003c\/li\u003e\u003c\/ul\u003e\u003cp\u003eFor reference, the Ford F-150 in these years is a full-size pickup offered with 2.7L and 3.5L EcoBoost V6 and 5.0L V8 engines, with the 3.0L Power Stroke diesel and 3.5L PowerBoost hybrid offered on selected years. The listing is written around the thirteenth-generation (2015-2020) F-150. The table does not separate trims; what matters is that the vehicle has factory stop-start and the connector shown in the photos.\u003c\/p\u003e\u003ch2\u003eWhat the factory system does\u003c\/h2\u003e\u003cp\u003eEach start of the Ford F-150 begins with Auto Start-Stop 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\u003eWhere owners notice the difference\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. Work with the ignition off. Seat each connector until its lock engages, then secure the module with the supplied ties or tape so it cannot rattle or touch pedals, steering parts or anything hot. Start the vehicle, press the stop-start button once, then restart to confirm the choice is held.\u003c\/p\u003e\u003ch2\u003eConditions the factory system checks\u003c\/h2\u003e\u003cp\u003eThe factory system will skip an auto stop for many reasons: battery charge below its threshold, cold coolant, high climate-control load, a steep grade, the hood or driver door open, or a 4WD or tow mode on vehicles that have them. 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\u003eKeep the battery healthy\u003c\/h2\u003e\u003cp\u003eThe module draws its power from the vehicle and does not change charging behavior. If your Ford F-150 sits for long periods, the same rules apply as without it: a maintainer helps, and a battery that tests weak should be replaced with the type specified for stop-start vehicles (usually AGM or EFB).\u003c\/p\u003e\u003ch2\u003eTroubleshooting notes\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\u003eScope of the module\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eComes out in the same way it went in, with nothing cut.\u003c\/li\u003e\n\u003cli\u003eCarries your stop-start choice over to the next drive.\u003c\/li\u003e\n\u003cli\u003eDoes not disable warning lights or diagnostic functions.\u003c\/li\u003e\n\u003cli\u003eFuel use changes only the way it would if you pressed the off button yourself.\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 (2018–2020 Ford F-150).\u003c\/li\u003e\n\u003cli\u003eYour Ford F-150 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\u003eInstall prep checklist\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eIgnition off, transmission in Park, fob outside the cabin.\u003c\/li\u003e\n\u003cli\u003eInstructions for your exact model at hand.\u003c\/li\u003e\n\u003cli\u003eConnector location confirmed against the photos before any panel comes off.\u003c\/li\u003e\n\u003cli\u003eA plastic pry tool for clips, if the connector sits behind trim.\u003c\/li\u003e\n\u003cli\u003eBoth connector locks fully engaged after fitting.\u003c\/li\u003e\n\u003cli\u003eModule and lead fixed in place, clear of pedals, steering and heat.\u003c\/li\u003e\n\u003cli\u003eTest: choose your Auto Start-Stop setting, turn the vehicle off, restart and check the indicator.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eQuick definitions\u003c\/h2\u003e\u003cp\u003e\u003cstrong\u003eAuto Start-Stop:\u003c\/strong\u003e Ford's name for the automatic engine stop-start feature on the Ford F-150.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eKey cycle:\u003c\/strong\u003e One switch-off and restart of the vehicle.

Diagnose and repair that first.\u003c\/p\u003e\u003ch3\u003eWill Auto Start-Stop come back on when I restart my Ford F-150?\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\u003eIs this the same part for every Ford?\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 my Ford F-150 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\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\u003eWhy does Auto Start-Stop 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\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\u003eWhat happens if I unplug it?\u003c\/h3\u003e\u003cp\u003eThe vehicle returns to the factory default, with Auto Start-Stop switched on at every start.\u003c\/p\u003e\u003ch3\u003eWhy does my Ford F-150 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 the stop-start button still work after installation on the Ford F-150?\u003c\/h3\u003e\u003cp\u003eYes. The factory button works normally. The module simply stores whatever you chose last.\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\u003ch2\u003eShipping, returns and warranty\u003c\/h2\u003e\u003cp\u003eShipping is free to the contiguous US.
