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 Pilot resets to on, and why a memory module is the way to keep your own preference.\u003c\/p\u003e\u003ch2\u003eFrequently asked questions\u003c\/h2\u003e\u003ch3\u003eWhich Honda Pilot years does this fit?\u003c\/h3\u003e\u003cp\u003eThe listed range is 2019–2022. Check the fitment table on this page against your exact model year.\u003c\/p\u003e\u003ch3\u003eWhy does my Honda Pilot 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\u003eWill Auto Idle Stop come back on when I restart my Honda Pilot?\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\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\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\u003eDoes the stop-start button still work after installation on the Honda Pilot?\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 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\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 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\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\u003eHow does it connect?\u003c\/h3\u003e\u003cp\u003eIt plugs in line with the factory connector named in the instructions.

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.

They typically use an AGM (absorbent glass mat) or EFB (enhanced flooded) battery that tolerates frequent cycling, along with a strengthened starter. The memory module does not change any of that hardware. When the battery reaches the end of its life, replace it with the same type and size listed for your vehicle, because a standard flooded battery is not designed for this duty.\u003c\/p\u003e\u003ch2\u003eBefore you plug it in\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003ePark on level ground, shift to Park, switch the ignition off and keep the key or fob away from the vehicle.\u003c\/li\u003e\n\u003cli\u003eRead the included instructions for your model before removing any trim.\u003c\/li\u003e\n\u003cli\u003eLocate the connector named in the instructions and compare it with the plugs on the module.\u003c\/li\u003e\n\u003cli\u003eUse a plastic trim tool where a panel has to be eased out, to avoid marking the dash.\u003c\/li\u003e\n\u003cli\u003ePress each connector until the lock clicks; never force a plug that does not line up.\u003c\/li\u003e\n\u003cli\u003eSecure the module with the supplied tie or tape so it cannot rattle or touch moving parts.\u003c\/li\u003e\n\u003cli\u003eStart the vehicle, set Auto Idle Stop the way you want it, switch off, restart and confirm the setting held.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eGlossary\u003c\/h2\u003e\u003cp\u003e\u003cstrong\u003eKey cycle:\u003c\/strong\u003e One switch-off and restart of the vehicle.

Turning it off with the button only lasts until the engine is shut down. Owners who sit in stop-and-go traffic, tow, or idle in drive-throughs often prefer it off, and that is where the repeated button press comes from.\u003c\/p\u003e\u003ch2\u003eA note on the battery\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\u003eTypical reasons to keep it off\u003c\/h2\u003e\u003cp\u003eDrivers usually switch stop-start off for comfort or habit. A restart at every stop is noticeable in a midsize 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\u003eConnecting it\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.

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\u003eDiagnostics first\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.

A synchronizing piston inside the rocker assembly disconnects the rocker arms for those cylinders from the cam, so their valves stay shut, and their injectors stop. Depending on generation, the engine runs on 3, 4 or 6 cylinders. The engine computer only allows this when its temperature and load conditions are met.\u003c\/p\u003e\u003ch2\u003eHow the harness works\u003c\/h2\u003e\u003cp\u003eBecause VCM is held off until the engine is warm, the coolant temperature input is the cleanest point to control it without touching software. The harness places a selectable resistor in the ECT1 signal circuit. Higher values shift the reading further. Pick the setting listed for your model in the instructions rather than going straight to the highest value.\u003c\/p\u003e\u003ch2\u003eWhat to expect\u003c\/h2\u003e\u003cp\u003eDrive the vehicle until it is fully warm and cruise at a steady, light throttle, which is where VCM used to engage. The engine should stay on six cylinders, so the vibration or hum that came with three-cylinder mode should not return. Keep an eye on the temperature gauge for the first few drives and confirm no warning lights appear. Expect light-load fuel economy to be a little lower than before.\u003c\/p\u003e\u003ch2\u003eWhy owners turn VCM off\u003c\/h2\u003e\u003cp\u003eVCM saves fuel, but many drivers prefer consistent behavior, particularly when towing or carrying a full load. The switching can feel like a vibration through the floor or steering wheel, and some engines show oil-related symptoms on the deactivated bank over time. Disabling VCM trades a little light-load economy for predictable engine operation.\u003c\/p\u003e\u003ch2\u003eFitting it\u003c\/h2\u003e\u003cp\u003eThe harness has a sensor-side plug and a vehicle-side plug. Fit it with the engine off and cool, confirm both locks click, select the resistance value from the instructions, and route the lead away from heat and moving parts. Removal is the reverse.\u003c\/p\u003e\u003ch2\u003eWhich VCM your engine has\u003c\/h2\u003e\u003cp\u003eHonda has used several versions of VCM. The first (2005–2007 Odyssey, early Pilot 2WD) switched between 3 and 6 cylinders. VCM-2, used on many 2008–2015 engines, added a 4-cylinder mode that idles one cylinder on each bank. VCM-3, on the direct-injected J35Y engines from around 2013–2014 onward, went back to 3 or 6. The harness works the same way on all of them, since each version waits for the engine to be warm before switching.\u003c\/p\u003e\u003ch2\u003eCheck the engine first\u003c\/h2\u003e\u003cp\u003eScan for codes and fix any existing misfire, oil-consumption or sensor problem first. A harness that changes the ECT1 reading will not cure a failing sensor or a cooling-system fault, and an engine that already fouls plugs on one bank needs inspection.

It shuts down the rear bank of the V6 during cruising and deceleration by disabling those valves through the VTEC system and stopping fuel delivery. Later versions added a 4-cylinder mode, and the newest go back to 3 or 6. Each switch is timed by the engine computer using speed, load, gear and temperature inputs.\u003c\/p\u003e\u003ch2\u003eWhat the resistance settings do\u003c\/h2\u003e\u003cp\u003eBecause VCM is held off until the engine is warm, the coolant temperature input is the cleanest point to control it without touching software. The harness places a selectable resistor in the ECT1 signal circuit. Higher values shift the reading further. Pick the setting listed for your model in the instructions rather than going straight to the highest value.\u003c\/p\u003e\u003ch2\u003eAfter installation\u003c\/h2\u003e\u003cp\u003eThe change is most noticeable at steady cruising speed on a warm engine, where VCM previously cut in. With the harness installed, that mode change should no longer happen. Acceleration and full-throttle behavior are the same as before. If a check-engine light appears, recheck the connections and the resistance setting against the instructions, then contact support with the code.\u003c\/p\u003e\u003ch2\u003eCommon reasons to disable VCM\u003c\/h2\u003e\u003cp\u003eOwners usually want three things: no shudder at steady cruise, smoother behavior at the moderate, steady speeds where VCM switches most, and fewer worries about oil getting past the rings on the idle bank. The harness gives consistent six-cylinder operation. It does not add power and it is not a repair for an engine that already burns oil or misfires.\u003c\/p\u003e\u003ch2\u003eVCM generations at a glance\u003c\/h2\u003e\u003cp\u003eThere are three main VCM versions: VCM-1 (3 or 6 cylinders), VCM-2 (3, 4 or 6 cylinders) and VCM-3 (3 or 6 cylinders, on the later direct-injection J35Y engines). The version depends on model year, and the notes above show which applies to each covered generation. Since all of them rely on the engine computer's temperature checks, the ECT1 approach applies across the range.\u003c\/p\u003e\u003ch2\u003eConnecting the harness\u003c\/h2\u003e\u003cp\u003eWith the engine cold and the ignition off, unplug the factory connector from the ECT1 sensor, plug the harness into the sensor, and plug the factory connector into the harness. Set the resistance selector to the value the instructions list, secure the harness away from the exhaust, belts and fan, and start the engine. The connection is inline, not at the OBD-II port. To remove it, reconnect the factory plug directly to the sensor.\u003c\/p\u003e\u003ch2\u003eCheck the engine first\u003c\/h2\u003e\u003cp\u003eScan for codes and fix any existing misfire, oil-consumption or sensor problem first. A harness that changes the ECT1 reading will not cure a failing sensor or a cooling-system fault, and an engine that already fouls plugs on one bank needs inspection.

Honda chose the rear bank, which is why owners describe the engine as running on three cylinders while cruising. Honda says the system looks at throttle position, vehicle speed, engine speed, gear selection and engine oil temperature before it switches, and brings all six cylinders back as soon as more torque is needed.\u003c\/p\u003e\u003ch2\u003eHow the harness works\u003c\/h2\u003e\u003cp\u003eThe engine computer will not switch to VCM until coolant temperature is in range. The ECT1 sensor reports that temperature as a resistance that drops as the engine heats up. This harness adds resistance in series, so the computer sees a slightly lower temperature than the actual one and keeps the engine in six-cylinder mode. The 68Ω, 82Ω, 100Ω and 120Ω settings are resistance values, not power levels; the supplied guide tells you which one to start with.\u003c\/p\u003e\u003ch2\u003eFitting it\u003c\/h2\u003e\u003cp\u003eWith the engine cold and the ignition off, unplug the factory connector from the ECT1 sensor, plug the harness into the sensor, and plug the factory connector into the harness. Set the resistance selector to the value the instructions list, secure the harness away from the exhaust, belts and fan, and start the engine. The connection is inline, not at the OBD-II port. To remove it, reconnect the factory plug directly to the sensor.\u003c\/p\u003e\u003ch2\u003eAfter installation\u003c\/h2\u003e\u003cp\u003eThe change is most noticeable at steady cruising speed on a warm engine, where VCM previously cut in. With the harness installed, that mode change should no longer happen. Acceleration and full-throttle behavior are the same as before. If a check-engine light appears, recheck the connections and the resistance setting against the instructions, then contact support with the code.\u003c\/p\u003e\u003ch2\u003eWhy owners turn VCM off\u003c\/h2\u003e\u003cp\u003eOwners usually want three things: no shudder at steady cruise, smoother behavior at the moderate, steady speeds where VCM switches most, and fewer worries about oil getting past the rings on the idle bank. The harness gives consistent six-cylinder operation. It does not add power and it is not a repair for an engine that already burns oil or misfires.\u003c\/p\u003e\u003ch2\u003eThree versions of VCM\u003c\/h2\u003e\u003cp\u003eThere are three main VCM versions: VCM-1 (3 or 6 cylinders), VCM-2 (3, 4 or 6 cylinders) and VCM-3 (3 or 6 cylinders, on the later direct-injection J35Y engines). The version depends on model year, and the notes above show which applies to each covered generation. Since all of them rely on the engine computer's temperature checks, the ECT1 approach applies across the range.\u003c\/p\u003e\u003ch2\u003eBefore you install\u003c\/h2\u003e\u003cp\u003eScan for codes and fix any existing misfire, oil-consumption or sensor problem first. A harness that changes the ECT1 reading will not cure a failing sensor or a cooling-system fault, and an engine that already fouls plugs on one bank needs inspection.

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.

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.

If your Honda CR-V 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\u003eDiagnostics first\u003c\/h2\u003e\u003cp\u003eA dead or weak battery, a charging problem or an unrelated module fault will change how Auto Idle Stop behaves with or without this part installed.

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.

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\u003eBattery and starter on stop-start vehicles\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.

They typically use an AGM (absorbent glass mat) or EFB (enhanced flooded) battery that tolerates frequent cycling, along with a strengthened starter. The memory module does not change any of that hardware.

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.

The module carries your last choice across that reset.\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\u003eDoes my Honda Odyssey 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\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 the stop-start button still work after installation on the Honda Odyssey?\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\u003eOrdering details\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).
