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\u003eNothing is reprogrammed in the engine computer.

The listing is written around the second-generation (2013-2020) Fusion. 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\u003eAuto Start-Stop is designed to default to on. The off switch (usually marked with an \"A\" inside a circular arrow) cancels it for the current drive. At the next start the system is armed again. That reset is intentional on the manufacturer's side, and it is the only behavior this module changes.\u003c\/p\u003e\u003ch2\u003eWhat to expect\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eLeaves no permanent change after removal.\u003c\/li\u003e\n\u003cli\u003eLeaves engine and transmission software untouched.\u003c\/li\u003e\n\u003cli\u003eLets you re-enable the system with the factory button at any time.\u003c\/li\u003e\n\u003cli\u003eHolds the stop-start button state between drives.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eConditions the factory system checks\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 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. Disconnect nothing else and splice nothing. Once both plugs are locked, tuck the harness where it will not be pinched when the panel goes back on. Test by switching Auto Start-Stop off, cycling the ignition and checking the indicator.\u003c\/p\u003e\u003ch2\u003eDiagnostics first\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. Then press the factory button once, switch the vehicle off, close the doors, give the electronics time to shut down, and start again. If it still resets, contact support with the year, trim and a photo of the connector.\u003c\/p\u003e\u003ch2\u003eKeep the battery healthy\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\u003eWhere owners notice the difference\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 Ford Fusion, the module turns that into a one-time choice you can still change whenever you want.\u003c\/p\u003e\u003ch2\u003eConfirm these points\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eModel year and model match a row in the table above (2017–2020 Ford Fusion).\u003c\/li\u003e\n\u003cli\u003eYour Ford Fusion has the factory stop-start button.

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 Start-Stop on the Ford Fusion resets to on, and why a memory module is the way to keep your own preference.\u003c\/p\u003e\u003ch2\u003eTerms used on this page\u003c\/h2\u003e\u003cp\u003e\u003cstrong\u003eAGM \/ EFB battery:\u003c\/strong\u003e Battery types designed for the frequent cycling of stop-start vehicles.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eNon-latching:\u003c\/strong\u003e A setting that does not stay where the driver left it after a restart.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eAuto Start-Stop:\u003c\/strong\u003e Ford's name for the automatic engine stop-start feature on the Ford Fusion.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eKey cycle:\u003c\/strong\u003e One switch-off and restart of the vehicle.

The factory button works normally. The module simply stores whatever you chose last.\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\u003eWhich Ford Fusion years does this fit?\u003c\/h3\u003e\u003cp\u003eThe listed range is 2017–2020. Check the fitment table on this page against your exact model year.\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\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\u003eWhy does my Ford Fusion 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 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 Ford Fusion 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\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\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\u003ch2\u003eWarranty and returns\u003c\/h2\u003e\u003cp\u003eFree standard shipping covers the contiguous US, with dispatch in 1–2 business days and 3–4 days on the road after that. You have 45 days to request a return (pre-approval required, 20% restocking fee, buyer-paid return shipping). The module is backed by a 3-year limited warranty.
