Someone help please.
I have a problem with my vauxhall insignia that is not starting. I keep getting a message to do with lack of communication between ECM and BCM. Somebody suggested that the problem may be caused by CANBUS module. When I looked at it, it had sign of burn a little bit and the pins had what looks like limescale on them.
Just wanted to check someone's knowledge on this before I buy a new one. My question is this:
Can I a damaged CANBUS module cause a disruption in communication between ECU and BCM? Can that is even prevent the vehicle from starting?
