BOB47 Posted August 19, 2008 Report Share Posted August 19, 2008 The abs light on my daughters car is on constantly. Just had brakes put on 3 months ago. It's a 99 Lumina. Pads and rotors still look brand new. Rear brakes are original but still look good. Any ideas? Quote Link to comment Share on other sites More sharing options...
Fireman31 Posted August 19, 2008 Report Share Posted August 19, 2008 (edited) Could be a few things, most likely it is a bad wheel speed sensor, or a bad/loose/corroded connection at one of the wheel speed sensors. That's where I would start. If everything checks out there, on to the ABS pump/module. If you have a ODB scanner, you should be able to see what ABS codes were thrown.

hot rod truck Posted August 19, 2008 Report Share Posted August 19, 2008 (edited) Bob, Since the brakes were done 3 months ago check both front wheel sensors. I take it the light has been on since the brakes were replaced. You'll have to pull the wheels and make sure to unplug and plug back in both sides. Also look for any damage to the wires to and from the wheel sensors, I believe they are built into the hub assembly. If the sensor is bad you'll replace the hub bearing assembly. A scanner should narrow it down to the wheel that is the problem (Autozone to the rescue for free ) If need be I can get you a Delco bearing at a brother-in-law price and ship it to you.

BOB47 Posted August 20, 2008 Author Report Share Posted August 20, 2008 Thanks for the help guys. I'll take it up to autozone tonight and have them read the codes. Quote Link to comment Share on other sites More sharing options...
