Chevrolet Repair Questions? Ask a Mechanic for Answers ASAP
Hi, I'm Cam. May I ask your first name? I am working to get you a fast accurate answer. About your vehicle, What are those 5 codes? They will indicate which module is not communicating.
Given the ABS light I suspect the ABS module or even the transmission module was damaged by the incorrect polarity.
try a reset.
Take both cables off both batteries if you have 2 batteries. Touch the ends of one set together for 10 seconds. This resets the entire vehicle and may correct this issue. Try it and see. Let me know.
ok, i'll try it tomorrow. I'm overseas, so its 1030 at night. All 5 faults have the same code. dtc 1, U0101
Ok, try and see. LEt me know.
