Power On With Engine Off?
This bulletin applies to 2014 Acura RDX models. If, when shifting into Park and shutting off the engine, the power mode stays in ON or ACCESSORY, the culprit may be a misadjusted shift cable.
If not adjusted properly, 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 the 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.
