Hello and welcome! My name is ***** ***** I can assist you with your question. The most common cause of this problem is a bad body control module or a bad diagnostic sensing module.

Expert:  AMEDEE replied 1 year ago.

Another common cause would be a bad electronic brake control module.

How do I go about diagnosing ii

Expert:  AMEDEE replied 1 year ago.

I would disconnect one module at a time until you get communication with your scanner.

Expert:  AMEDEE replied 1 year ago.

Once communication starts, you know the last module you disconnected is bad pulling the rest off line.
