Alright I have a 2002 escalade. It went to the dyno the other day to get tuned. The tuner pulled the ABS fuse from under the hood before the dyno for saftey reasons. As i was driving home i noticted that when im at about 2-6mph and lightlty push the breaks the abs kicks in and i get no breaks. If i push really hard on the breaks it stops fine. The ABS light came on then goes off. Any suggestions on what might have happend?

 

I know the pickups in those years had some problems with the sensors themselves. Rust builds up under the sensor and makes the sensor think that the brakes are locking which activates the abs at low speeds. The avalanche is basically the same thing so I would check that out. Why it happened after the fuse I'm not sure, maybe just coincidence.

 

The abs sensors go bad. I've had mine replaced and I still have problems with it. my ABS light and my parking brake light comes on and my ABS goes out the window. Good luck with your issue.
