Hi Jack! I've got a question for you - I'm trying to add a kill switch to the starter button with starter wiring harness, do you know which color would be the B+ I've done some readings and kept getting blue and white as the ACC and the orange/brownish color as the B+ but wanted confirmation. Maybe you could help provide an answer.
Ignition switch (push button) output power to BCM is terminal 4 on connector M101, it is a light blue wire. Terminal 1 in M101 is black, that's the ground wire.
2013 qx56 was shorted out by crossed cable wires no power to starter from red wire from ipdm does that mean bad ipdm unit everything else works in vehicle
It's hard to know if your IPDM is bad with only what you've shared, but it is possible the IPDM was damaged. I have some other ignition trouble shooting videos you might view and do a little more troubleshooting. As for the starter specifically, the transmission control module also plays a role in allowing power to go to the starter solenoid. I've got a short video about testing that also. I wish I had a quick easy answer for you, but it just isn't that simple. IPDM are too expensive to guess at and buy a part you might not need.
