Tips: Honda Engine Shuts Off, but Power Mode Stays in ‘ON ‘ or ‘ACCESSORY’

Honda Engine Shuts Off, But Power Mode Stays in ACCESSORY

The culprit behind this issue could be a misadjusted shift cable.

All models with one-push start 

If your customer experience issues cycling the ignition with the push button, the culprit could be a misadjusted shift cable. If the cable is not adjusted correctly, it puts pressure on the shift lever, keeping the park pin switch from opening. The power control unit needs the park pin switch position input to switch the power mode to VEHICLE OFF (LOCK). 

Using a scan tool, go to the ONE-PUSH START/PCU Data List. Scroll down to AT SHIFT POSITION P and AT SHIFT POSITION P-PIN. Shift into Park while keeping your foot on the brake pedal. Then, without pressing the release button, pull back on the shift lever (toward Reverse). The AT SHIFT POSITION P signal should read ON and the AT SHIFT POSITION P-PIN signal should read OFF. 

Another test is to shift into Reverse while pressing the brake pedal. Then, press the release button and gently push the shift lever into Park. When it goes into Park, the AT SHIFT POSITION P signal should then read ON and the AT SHIFT POSITION P-PIN signal should read OFF. If you don’t get the expected results from either of those tests, refer to the electronic service manual and adjust the shift cable.
