No PCM COMMUNICATION
I have a 2006 Sterling 9500 with Mercedes-Benz , engine. I need the wiring diagram for the motor control module. I have no communication with any for the modules, tcm, abs. Vehicle was running great. Was shut off and now wont start. Im assuming one of the power wires going to the pcm is bad. The vehicle is a plow truck. Any help would be great.
