It stores the last stop-start setting you chose, so if you turned Engine Stop-Start (ESS) 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, 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.

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\u003eBefore blaming the module\u003c\/h2\u003e\u003cp\u003eA dead or weak battery, a charging problem or an unrelated module fault will change how Engine Stop-Start (ESS) behaves with or without this part installed. Scan the vehicle for stored codes, test the battery and confirm the system works normally with the factory button before installation. That baseline makes any later issue easy to pin down.\u003c\/p\u003e\u003ch2\u003eWhat to expect\u003c\/h2\u003e\u003cul\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 change engine power, transmission shifts, emissions calibration or fuel trims.\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\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\u003eWhen the engine will not auto-stop anyway\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\u003eWhere it connects\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\u003eWhere owners notice the difference\u003c\/h2\u003e\u003cp\u003eStop-start saves the most fuel in long idles, but plenty of drivers would rather keep the engine running. Common reasons: towing or hauling, where an engine restart under load is unwelcome; drive-thru lines and parking lots, where the engine cycles on and off every few feet; hot days, when the A\/C compressor stops with the engine on many vehicles; and stop-and-go traffic where the restart delay is noticeable when pulling into a gap. On a daily driver, any of these can mean a button press at the start of nearly every drive.\u003c\/p\u003e\u003ch2\u003eFitment check\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eModel year and model match a row in the table above (2018–2024 Jeep Wrangler).\u003c\/li\u003e\n\u003cli\u003eYour Jeep Wrangler has the factory stop-start button.

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 Engine Stop-Start (ESS) on the Jeep Wrangler resets to on, and why a memory module is the way to keep your own preference.\u003c\/p\u003e\u003ch2\u003eTroubleshooting after installation\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.

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\u003eWhy does my Jeep Wrangler 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\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\u003eDoes my Jeep Wrangler 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\u003eCan I remove it later?\u003c\/h3\u003e\u003cp\u003eYes.
