australian car, ve commodore, have no communication with abs and trans computer, trying to isolate which module is the cause, on the system is abs, trans, bcm, ecm and steering angle sensor
Have you tried to disconnect each module one at a time to see which one is causing system to go down............Also have you checked all the fuses............?
yes like ashraf said, disconnecting one module at a time can help identify the can bus issue. I will start with the abs first, its the most likely suspect but anyone could do it. good luck.
