GMC Troubleshooting Questions? Ask a Mechanic for Answers
Hello my name is***** am an ASE Master Technician and I am glad to help you out with your question.
It is not a recall.
The first step to diagnosing this problem is getting the codes scanned for the traction control. Since you have a light on the dash there will for surely be a code in there. We need this code to go any farther with this problem, yes, it could be a wheel speed sensor. Without codes we have no idea which one.
You will need a shop scan tool as well, a simple code reader will not work in this case.
Ok let me know what you find.
