VX SS BCM-ECU-PCM wiring

Post by ImNotHereEither »

Hello fellow Lion Tamers! :punk:
I have a VX SS with some pretty serious wiring gremlins. :sad2:
I'm chasing the wiring diagrams to suit the BCM, PCM and ECU.

Essentially I cannot get my scan tool to connect to or read the BCM. I've tried another BCM with no luck on that front either.
I HAVE however, connected to a different VX's BCM successfully, so I know the issue is not with the scan tool.

I can also get live engine data from MY VX, so obviously there's an issue in the BCM wiring somewhere.

I've already checked the ABS module and discounted that as the issue.

This is doing my banana in :rant:

Any help would be greatly appreciated.

Cheers, y'a'll.
It's not how fast you hit the wall that matters, but how far you punch through it :driving:

You’ll find them in the wiring section.

But..... have you checked the bcm fuse? Silly I know but they do go.
