Code 12 Issue
If I've learned correctly the cycling of code 12 means there's no codes to report however I still have a abs and asr light. I recently changed my cam position sensor and my brake position sensor on the master cylinder. What am I forgetting? That's not much to go off but any clues who be appreciated

Re: Code 12 Issue

Re: Code 12 Issue
Code 12 is an ECM self test. ABS and ASR codes are from CCM.

Re: Code 12 Issue
Not knowing what year, I can't tell whether you have 12 pin or 16 pin ALDL connector.
Below article should help with your diagnosing the problem. I can't immagine cam position sensor being related but wheel speed sensor replacement may be related. https://tech.corvettecentral.com/201...trouble-codes/ |
