Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a flat surface and securely parked.
Disconnect the negative terminal of the battery to prevent any electrical shorts.

2. Check and Replace Wheel Speed Sensors

Tools Required: Socket set, multimeter, torque wrench.
Remove the wheel corresponding to the faulty wheel speed sensor.
Disconnect the wheel speed sensor connector.
Use a multimeter to test the sensor's resistance; it should be within the manufacturer's specifications.
If the sensor is faulty, remove the retaining bolt and replace it with a new wheel speed sensor.
Reconnect the sensor and ensure it is securely fastened.

3. Inspect and Repair Wiring and Connectors

Examine the wiring harness for any signs of wear, fraying, or corrosion.
Repair or replace any damaged wires or connectors to ensure proper electrical connections.

4. Verify Brake Fluid Level and Condition

Check the brake fluid reservoir for the correct level; top off with the manufacturer-recommended brake fluid if low.
If the fluid is contaminated, perform a brake fluid flush and replace it with new fluid.

5. Reconnect Battery

Reconnect the negative battery terminal and ensure it is tightened securely.
Start the vehicle and check if the traction control light remains illuminated.

6. Clear Error Codes

Use the OBD-II scanner to clear any error codes related to the traction control system.
Perform a test drive to monitor the system's operation and ensure the light does not return.
