Cadillac Repair: 1991 4.9 SeVille, diagnostic test, test procedures

Question
ccr on system check came up.
What do I look for or do?

Answer
CCR = Command Control Ride. This is usually a dealer fix item. However, I can provide you with all the necessary information to extract the code from the control module in the trunk but I don't know if you will be able to figure out how to read the codes. Once I have the code # or #'s I can then give you the diagnostic test procedures to test and fix the fault. Contact me at: onlineautohelp@msn.com
