QuestionAfter seeing the "Service Ride Control" light displayed on my 94 Cadillac Seville, I held the OFF and WARMER buttons to see No PCM, ICP, ACP, SIR, TCR; Code S036 History; Code SO44 History; Code S063 History; PCM? - What does that mean and what should I do? Thanks for your help
AnswerAriana,
S036 = ELC compressor circuit short to ground/open
S044 = Lift/dive signal fault
S063 = R/R position sensor fault
First thing you should do is clear the codes. They are all "history" codes so they may have simply been a one-time intermittent fault. Once cleared, see if all reoccur. By the looks of the codes, it seems like you may a have some bad connections or short circuits to take a look at. Any work been done to the car recently that might explain this?
