Re: ABS/Trac Off light
Check the wiring for the right front wheel speed sensor to start. If it looks O.K. you can check the output of the speed sensor with a volt meter set to a/c voltage. Compare to the other side to see if the readings are the same if not replace the hub/bearing assembly.

Re: ABS/Trac Off light
To confirm what AirJer said, check the wiring for the wheel speed sensor. Mine was wrapped and I had to cut the sheath off to view the actual wires. In my case the wires were good, so I ended up replacing the wheel hub bearings on the front and the errors went away.

Re: ABS/Trac Off light
Welcome to AF ame92 !
Sounds like you have a bad wheel speed sensor or as stated above possibly a short in the wiring. They should ohm out around 2000 ohms i think. Also If you have it on jack stands and you rotate the wheel(in nuetral) while checking the ohms reading, it should fluctuate smoothly as the speed increases/decreases, not erraticlly jumping around. If it's jumping around the HUB sensor is bad. And i would NOT remove that wire protector completely or you could have other issues down the road.
