ABS and TRAC lights illuminated GP 98 GT

I recently had an oil change on my GP 98 GT and the mechanic removed the right front wheel to check the remaining life of the brakes. The next day the ABS and TRAC lights came on after driving about 5Km. After I made my first stop, they did not stay on after I started again and have been working normally for about 3 weeks. They came on again yesterday and after I stopped and restarted, they went off again. Can anyone shed some light on this?


Thanx

Check the wiring harness and electrical connector to the ABS wheel sensor on that wheel. The connector is located on the back side of the hub. Make sure it is not loose and tight. Also, check for damaged/frayed/cut wiring on the harness.
