Traction control light on

Your going to need to have your ABS/traction computer scanned for codes. Let me know the exact code numbers you have not code descriptions? A diyer auto parts store scan tool cant read those.

Hi,

Don't laugh, but the first thing I recommend is checking the brake fluid level. If that is full, then my first suspect is a bad wheel speed sensor. You can determine if it is a sensor by using a scanner that can read ABS codes or you can test one wheel at a time.

Here is a link that explains how to check a wheel speed sensor. It's not hard to do.

Here is a link that shows in general how one is replaced:

If you provide the engine size and if it is 2 wheel or 4 wheel drive, I can provide the specifics for locations and replacement.

Let me know if this helps or if you a have other questions.

Take care,
Joe
