Can Anyone Help Me?????

Ok...I've been reading on here that this happens alot. But mine is a little diffrent. Well my anti-Brake light and no trac light comes on after I have been driving a little while. It seemd like it comes on when I hit a small bump while driving down the road. I took it to Auto Zone today. They couldnt tell me anything. Does it sound like a loose wire???? Its driving me nuts..

Welcome to AF.

Autozone cannot scan for GM ABS/Chassis codes. You need an ABS Capable scanner.

At each wheel hub is an electrical connector and wiring harness that goes to the wheel sensor on each hub. Also, inspect the wiring that runs along the lower control arm at each wheel. Check all of that out first. If thats OK then you may have a bad hub/bearing.

Definately sounds like wheel speed sensor. Unfortunately, you have one in each wheel and they're part of the hub/bearing assembly. Not hard to change, but not always cheap parts.
