There is no "traction control" unit. It is a function that is controlled by the PCM & EBTCM with inputs from the wheel speed sensors. Pull the DTC's. Post them and their definitions.

PCM = Powertrain Control Module

C1225 - Left Front Excessive Wheel Speed Variation
C1232 - Left Front Wheel Speed Circuit Open or Shorted

Check the wheel speed sensor connection on the back of the hub. If it is good, it's probably time to change the hub & bearing assembly.
