It stores the last stop-start setting you chose, so if you turned Auto Idle Stop off on one drive, it stays off the next time you start the engine. It plugs in line with the factory connector named in the instructions. Both ends are factory-style plugs, so nothing is cut or spliced.\u003c\/p\u003e\u003cp\u003eThe factory button stays in place and still works. Press it and the module stores the new choice. Unplug the module and the vehicle goes back to stock behavior.\u003c\/p\u003e\u003ch2\u003eVehicles and years covered\u003c\/h2\u003e\u003cp\u003eThis part is listed for these vehicles, all marked 100% fitment match:\u003c\/p\u003e\u003cul\u003e\u003cli\u003eHonda Passport: 2026\u003c\/li\u003e\u003c\/ul\u003e\u003cp\u003eThe listing is written around the third-generation (2026-up) Passport. 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\u003eHow Auto Idle Stop behaves from the factory\u003c\/h2\u003e\u003cp\u003eWith Auto Idle Stop active, the engine shuts off when the vehicle comes to a stop and restarts when you lift off the brake or press the accelerator. The off button is a manual override for that drive only. Turn the ignition off and back on, and the system defaults to on again, so drivers who prefer it off end up pressing the button at the start of every trip.\u003c\/p\u003e\u003ch2\u003eWhere it connects\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. 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\u003eBefore blaming the module\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\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 two-row midsize 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. 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\u003eWhat the module does and does not do\u003c\/h2\u003e\u003cul\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\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\u003c\/ul\u003e\u003ch2\u003eConditions the factory system checks\u003c\/h2\u003e\u003cp\u003eEven with Auto Idle Stop 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\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\u003eCheck before you order\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eModel year and model match a row in the table above (2026 Honda Passport).\u003c\/li\u003e\n\u003cli\u003eYour Honda Passport 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 Idle Stop on the Honda Passport resets to on, and why a memory module is the way to keep your own preference.\u003c\/p\u003e\u003ch2\u003eQuick definitions\u003c\/h2\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\u003eKey cycle:\u003c\/strong\u003e One switch-off and restart of the vehicle.

If any are outside range it keeps the engine running. The module does not affect those checks.\u003c\/p\u003e\u003ch3\u003eWhich Honda Passport years does this fit?\u003c\/h3\u003e\u003cp\u003eThe listed range is 2026. Check the fitment table on this page against your exact model year.\u003c\/p\u003e\u003ch3\u003eDoes the stop-start button still work after installation on the Honda Passport?\u003c\/h3\u003e\u003cp\u003eYes. The factory button works normally. The module simply stores whatever you chose last.\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 Idle Stop come back on when I restart my Honda Passport?\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\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 Idle 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 Idle Stop switched on at every start.\u003c\/p\u003e\u003ch3\u003eDoes my Honda Passport 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 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\u003eIs this the same part for every Honda?\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. Both ends are factory-style plugs, 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\u003eShipping and support\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.
