I have a Thomas bus with air brakes the park brake won’t release and the lights are going crazy and nothing is working I’ve had one before do this that was under warranty and it was the chassis module they seem to think the same thing but they are all on back order could it be Something else or does anyone know where I can get one
ebay, truck salvage yards, I hope here we never get any c2's again , wiring is time consuming, and service link is not supported and you have to have DDDL , alright if you had Detroit's in your fleet and not an ebay DDDL cause you need to connect to server
OEM trained in wiring and all engine platforms for over 20 years
I'd check the plugs on the chassis hub module for water intrusion. Also, check the J1939 terminating resistor that hangs down the left side of the chassis where the engine and transmission meet. I had one take on water and the bus went crazy
