Need tech info on a Pacifica

"1. Start the engine and remove the starter motor relay in the IPM. Check voltage in cavity # 85; there should be no voltage. If any voltage is present, the PCM will think the engine is in crank mode and will not energize the relay.

2. If voltage is present, cut wires that can leak voltage on circuit. Starting with pin #4 C4 from IPM circuit #T751 Yellow wire, pin #1 C7 circuit T751 Yellow wire and pin #5 C1 circuit T750. "


Pin #5 on connector 1 circuit T750 wire is a YL/GY wire.

I would pull the battery and battery tray and locate these wires listed above coming out of the IPM and check your harness closely, these three circuits are the possible source of finding voltage on cavity 85 of the starter relay . The pcm monitors this circuit and with a voltage it is not energizing /grounding the acc. relay.
