I have a 2001 trailblazer and my abs light has been coming on and off. The rear brakes needed to be replaced so I did the calipers,brackets, all hardware,rotors and pads. I unhooked the battery and the light stayed off. Then the front wheel bearing went, light back on. I replaced the wheel bearing light off. Drove for a week and light on. Now the other wheel bearing is making a grinding noise,so I replaced that. Light is still on so any ideas what it can be?

 

If the light is on, that means there are codes stored. Get the ABS system scanned and let us know what the codes are and we'll go from there.

 

I will thanks. Does autozone scan for abs codes? Hey I see your from the syracuse area. Im originally from Binghamton NY. I moved out to Wisconsin 10 months ago, I loved going to the dinosaur BBQ

 

Depends on whether they use their higher $$ scan tool or not. If they are just using a typical generic OBD2 scan tool, they would not be able to access the ABS system.

I live in the Finger Lakes. Don't get out to restaurants in the Syracuse area all that much, but have been to the Dinosaur Bar-b-que in Rochester.
