Thread: ABS/Trac Off Lights on

My ABS and Traction control off light came on the other day and now comes on nearly everytime I drive it. Has my ABS module gone bad? Any other common things cause this?

yes, tach works.

We need a sticky for this problem since it comes up so often. 99% of the time it is a bad speed sensor on one of your four wheel bearings. With a scanner that can read ABS codes you can find out which one in a few seconds.

I'll run a scan tonight and post the code. Thanks!

Check your wires on both of your front hubs.. If they are cut it will disable your ABS and TCS.

I found a place to scan the codes for no charge! Was the right front wheel throwing the code. Since it had some play in the bearing also, I didn't hesitate to replace the hub. Got a Timken hub/bearing for 107 from rockauto and put it in. Still had the friggin ABS light on. Found there is an issue with the harnes and dorman makes a replaecment harness. Back to rockauto for 27 bucks. In the meantime, doing the LIM gasket on my daughters car, so haven't installed the harness yet.

I had the same problem with my 98 GT. Replaced the front right hub and the light came on in about a week. I looked closer at the connection and it had some play so I took a small zip tie and put around the connection. That cured it. I didn't feel like replacing any harnesses.
