Solution

1. Preparation

Gather tools and parts required for the repair.
Disconnect the vehicle battery to prevent electrical shorts during inspection.
Ensure the vehicle is on a flat surface and secured with wheel chocks.

2. Inspect Wheel Speed Sensors

Locate the wheel speed sensors at each wheel hub.
Clean any dirt or debris from the sensors and connectors.
Use a multimeter to check the resistance of each sensor; compare readings to manufacturer specifications.
Replace any faulty sensors with new ones.

3. Examine Brake System

Check the brake fluid reservoir; top off with the appropriate fluid if low.
Inspect brake lines for leaks or damage; replace any damaged lines.
Ensure that brake pads and rotors are in good condition; replace if worn.

4. Test and Replace Traction Control Module (if necessary)

Reconnect the battery and use the OBD-II scanner to clear any error codes.
Drive the vehicle to see if the traction control light reactivates.
If it does, remove the traction control module and test it with a multimeter.
Replace with a new module if it fails the test.
