Scotty you didnt read this fully.
He gets a noise and his traction control light comes on. Though the ABS noise is normal, the T/C light is not a normal thing to have happen when turning in reverse.
If it was my car, I would remove and clean all connectors from the ABS hubs, check wires at the ABS module and see if anything else looks odd. Or if you had a scan tool you could watch all the ABS sensors at once and see if one drops out and thats why the light trips.
