Having a problem with the MC. I was having the typical problems with my traction control system (traction control activating when backing out of parking spaces, service traction light intermittently) so I had the ECU read and it was throwing a code for the front right wheel speed sensor. I replaced that hub bearing this past weekend, and now those issues have stopped, but now after I drive the car for 1-2 miles, the "TRAC OFF" light comes on with no messages being displaced on the screen. If I push the traction control button, nothing happens, I can't get the traction control to turn back on (unless I turn the car off then on again).

This is a new one for me, anybody experienced this one before? Thanks in advance!

 

Have the PCM read again using a scanner (Tech II or equivalent) capable of reading all (powertrain/chassis/body) codes.

 

Also check the wiring of the hub you just changed
