The ABS light stays on along with the Traction Control light.
These lights come on after the car is started. The last time I had the car in the shop
I had 4 MM of wear left on the front brakes. The rear brakes were replaced last year.
The car has 94 K mileage. The front brakes were replaced with 62 K on them. Rear brakes had 87 K when they were replaced. The car had 91 K when the front brakes
had 4 MM wear left. All the fuses check out OK. The ABS has s solenoid. Maybe that is bad? If the front brakes need to be replaced would that be the cause of the
warning lights to stay on?
Typically when both these lights come on it may be a bad wheel speed sensor, which means the wheel bearing will need to be changed. I would recommend taking it to the shop to have that looked at. Hope this helps!
The ABS and traction control systems work together. When a fault is detected in one system, both systems are disabled and both lights come on. I agree with JJ. Have the computer scanned for trouble codes and see which speed sensor (hub assembly) it is. HTH. -Jim
1) make sure your brake fluid is topped off 2) have autozone do a diagnostic check and pull codes. 3) could be one or more of your ABS speed sensors (NOT wheel bearing)
The speed sensor is built into the wheel bearing on some GM vehicles like my 2008 Buick Lacrosse so if the speed sensor is found to be defective the bearing unit has to be replaced - YES wheel bearing.
I have know answer. But I have the same problem. Had wheel bearing replaced but both indicator lights are still on.
I replaced the wiring harness to the left front wheel. A local auto parts store always carries the harness in stock because it is requested by repair shops so often. Problem solved :)
I forgot to mention that I did prove the problem I had to the left front wheel. I bounced both front sides of the vehicle while parked and monitored the indicator lights. It seemed that the left side would activate the lights. I took a chance and assumed there was a short in the harness on the left side and replaced that harness. The harness replacement that I purchased would fit both left or right side. Maybe I got lucky picking the left side. This is not very scientific but it isn't brain surgery either. Cost under $60.00 plus my time. I am a DIY backyard mechanic. Makes you wonder "why can't 'real' mechanics find this first before they replace bearings?"
how would bearings have anything to do with ABS lights? makes no sense...
Harness, YES, makes all the sense in the world ;)
My first post in this thread stated 'The speed sensor is built into the wheel bearing on some GM vehicles like my 2008 Buick Lacrosse so if the speed sensor is found to be defective the bearing unit has to be replaced - YES wheel bearing'. That is how the wheel bearing has something to do with the ABS light. Search the internet to find out more.
You are 100% correct, Beinghelpful46. Many GMs are like that. In fact at NAPA, where I work, part number BR930548K is a very popular GM hub bearing assembly. The wire connector is a sure sign that the ABS wheel sensor is built into the hub bearing assembly. This part number fits many GM cars made from about 1997 until about 2010. HTH. -Jim
