Chevrolet Repair Questions? Ask a Mechanic for Answers ASAP
Hello, my name is ***** ***** I'm here to help get your problem solved.
These codes most likely mean whatever module that is setting them is failing. You can verify connectors are in good condition and tight at module if so next step would be to replace. Let me know if you have more questions, thanks.
No problem, module will most likely need to be reprogrammed at dealership which will be around a hour labor. Let me know if there is anything else I can do. Thanks again and have a Happy New Year!
