ABS Warning Light

My ABS warning lights come on periodically.

ABS Warning Light

Postby WME [OP] » Jul 24 2010, 5:05pm

My truck has 200K miles on the original brakes, pads still have plenty of thickness and the ABS system seems to be functioning normally. Seems to be constant if I have my foot on the brake as the computer cycles through boot up and intermittent if I do not apply any brake until boot up is complete. Any thoughts on what may be causing this?

Hmmm. Your write up is very confusing. I'll try to answer it based on what I think you are asking.

If your ABS light is coming on then some fault codes are being set. You will need to find a local mechanic who can pull the codes for you. I'm told Autozone does it for free.

Heads up. GM had a recall on many full size trucks for abs issues because of rust on reluctor wheels (toothed wheels on your wheel bearing) I hope this helps.

Auto Zone cannot pull ABS codes, however if I had to guess you may have a poor connection at the wheel speed sensors. I would un-plug them and see if there is corrosion. Also, by original brakes, were you refering to the pads as well?
