Need tech info on a Pacifica

They have had issues with the integrated power module wiring (IPM)

I copied and pasted a tech tip from our shop information called Identifix , which is info and known fixes collected from shops all around:

Customer Concern: Accessories are inoperative; no audio, compass, windows, wipers speedo, etc. BCM codes loss of communication.
Average Reported Mileage: 124336
Tests/Procedures: 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.

3. Check powers and grounds. On the bottom of the IPM, test all of the power and ground supplies for the IPM. There are several that need to be tested, one common one is a Black/Yellow ground wire at the C5 connector on pin 14.
Tech Tips: Any power or ground supply to the IPM will cause the IPM to not function correctly.

1. Verify the ignition switch position is indicated correctly in the Body Control Module (BCM) and the Integrated Power Module (IPM). The ignition switch has a built in position sensor that reports the position of the ignition switch to the BCM. The BCM then broadcasts the position to all the modules that need the information on the BUS circuit.

2. Check circuit T751 and T752 at the Intelligent Power Module (IPM) for voltage with the engine running. These circuits should have battery voltage only during cranking and should go to 0 volts with the vehicle running. If there is any voltage on these circuits, the IPM will de-energize the accessory relay, which cause the named circuits to shut down, even with the vehicle running. Voltage typically comes from the wire harness due to battery acid from the battery. Voltage gets tracked into these circuits and cause the IPM to shut down the accessory relay. Another cause could be any add-on system such as a remote starter system wired into these circuits.
