My girlfriend has an 05 cobalt LS, the ABS comes on at low speeds even on dry roads, every now and then the traction control light and ABS lights come on but not very often. The car has 107xxx miles, and rear drum brakes. If someone could point me in the right direction it would be much appreciated. I have already jacked it up and checked all the wheel bearings for play, they are all tight. Thanks in advance

 

To find the problem you will need to scan the brake module, and then go from there. You can not figure out the problem without more info.

 

Is there anywhere I can get the brake module scanned other than the dealer? They want $97 just to scan it, called autozone and they only scan for "check engine" lights.

 

you would have to buy a scanner. you can get em pretty cheap. Sounds to me you have a wheel speed sensor out, just get that scanner on and figure out which one is reading out of wack

 

ok Ill pick up a scanner tomorrow, thanks guys

 

try cleaning up the wheel speed sensors before you replace them. they get coroded and do not work right. had the same problem with a cavalier and that fixed it. its a pia you have to pull the calipers and rotors to get to them.
