2002 bmw381i crank/ no start / instrument cluster and turn signal not responding
The only modules communicating are pcm, abs and tcm. Took out the instrument cluster and I hade power and grounds on certain pins. I am thinking the communication bus may be the problem. Does anyone have a wiring diagram?
