Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the ignition is off.
Disconnect the battery to prevent any electrical issues during repairs.

2. Inspect Wheel Speed Sensors

Locate the wheel speed sensors on each wheel hub.
Remove any dirt or debris from the sensor area.
Disconnect the sensor connector and check for corrosion.
Use a multimeter to test the sensor resistance; replace if out of specification.

3. Check Wiring and Connections

Visually inspect wiring harnesses connected to the wheel speed sensors for frays or damage.
Reseat any loose connections.
Repair or replace damaged wiring as necessary.

4. Brake System Inspection

Check the brake fluid level in the master cylinder and top off if low with the recommended fluid type.
Inspect brake pads and rotors for wear, replacing them if necessary.

5. Test Traction Control Switch

Locate the traction control switch on the dashboard.
Use a multimeter to ensure the switch is functioning properly.
Replace the switch if it fails to operate or shows no continuity when pressed.

6. Reconnect Battery and Clear Codes

Reconnect the vehicle's battery.
Use the OBD-II scanner to clear any error codes.
Start the vehicle and check if the traction control light remains off.
