Tools Required: Socket set, cleaning brush, brake cleaner
Remove the wheel on the affected side using a socket set.
Locate the wheel speed sensor, usually mounted on the wheel hub assembly.
Clean the sensor and its mounting area using a brush and brake cleaner.
Reinstall the wheel and lower the vehicle.

3. Check Brake Fluid Level

Tools Required: None
Open the hood and locate the brake fluid reservoir.
Check the fluid level against the marked indicators on the reservoir.
If low, top off with the appropriate brake fluid as specified in the owner’s manual.

4. Inspect Wiring and Connectors

Tools Required: Multimeter
Visually inspect the wiring harness and connectors related to the traction control system for frays, breaks, or corrosion.
Use a multimeter to test for continuity in the wiring.
Repair or replace any damaged wires or connectors as necessary.

5. Test Brake Light Switch

Tools Required: Multimeter
Locate the brake light switch, usually situated near the brake pedal.
Use a multimeter to check for proper operation by ensuring continuity when the brake pedal is pressed.
Replace the brake light switch if it is faulty.

6. Reconnect Battery

Reconnect the negative battery terminal securely.
Start the vehicle and check if the traction control light remains off.
