GMC Troubleshooting Questions? Ask a Mechanic for Answers
Hello and welcome! My name is ***** ***** I can assist you with your question. This code is most likley caused by a bad Electronic brake control module provided it has power going to it. Just be sure to verify 12 volts on the red wire going to the unit before replacing it. If all checks out good, the EBCM is bad and will need to be replaced.
I am glad I can help!
