First off, I'm used to dealing with older vehicles without brains! My Boy's 07 MCS was throwing 131&132 cc-id codes since we picked it up 5 months ago. Step 1, figure out what the little symbol meant. Step 2, find out how to get the corresponding code number for the symbol. Step 3, find out what that code translated to in english. Step 4, translate that English, into something I could work with. Ending message........http://www.endtuning.com/ccidcodes.html, list of cc-id codes. 131 & 132 translate into left and right front parking lights.
