I have a 2004 Avalanche with ~63k miles on it. For probably 2 years now if you punch it down to super pass someone the T/C light would come on and every once in a while the ABS light would come on also. After 30-60 seconds they would go off.

Today the ABC, Parking Brake, and T/C light came on along with a message "Service Brake System". Even after driving for 10 more minutes and stopping and restarting the car the ABS light remains on. I figure it is time to get to the bottom of this.

Has anyone had this same thing happen?

 

Similar on my 07 Avalanche, it was a wheel motion sensor on one of the rear wheels. It was 125.00 at dealership to fix. My error codes were abs light on, service brake system, service stabillatrack.
