Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a flat surface and secure it with wheel chocks.
Disconnect the negative battery terminal to prevent electrical shock.

2. Check and Clean Wheel Speed Sensors

Locate the wheel speed sensors on each wheel hub.
Remove any dirt or debris from the sensor area using a clean cloth.
Inspect sensors for physical damage; replace if needed.

3. Inspect and Repair Wiring

Examine the wiring harness connected to the traction control system for any signs of wear or damage.
Use a multimeter to test for continuity in the wiring.
Repair or replace any damaged wires or connectors found during inspection.

4. Test Traction Control System

Reconnect the negative battery terminal.
Start the vehicle and perform a test drive in a safe environment to check if the traction control light remains off.
If the light persists, consider replacing the traction control module.
