Honda Ridgeline Stuck in Power Mode

Order Reprints

This bulletin applies to 2017 Honda Ridgeline vehicles equipped with one-push start. The engine may shut off but the power mode may stay in the on or accessory position.

When you shift into Park and shut off the engine, does the power mode stay in ON or ACCESSORY? The culprit may be a misadjusted shift cable. If 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). 

To find and fix this problem, hook up the HDS and 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.
