Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the ignition is off.
Disconnect the negative battery terminal to ensure safety.

2. Inspect and Clean Wheel Speed Sensors

Remove the wheel covers or tires if needed for better access.
Locate each wheel speed sensor; they are typically mounted near the brake rotor.
Disconnect the electrical connector from each sensor.
Clean the sensor and the area around it with brake cleaner to remove debris.
Reconnect the electrical connector firmly.

3. Check ABS System

Inspect the ABS module and wiring harness for any visible damage or corrosion.
Use a multimeter to test the voltage and continuity of the ABS system wiring.
If any shorts or open circuits are found, repair or replace the affected wiring.

4. Traction Control Switch Check

Locate the traction control switch on the dashboard.
Remove the switch using a trim removal tool if necessary.
Inspect the switch for damage and ensure it is functioning correctly by testing continuity with a multimeter.
Replace the switch if it is faulty.

5. Brake System Inspection

Check brake fluid levels in the reservoir; top off if necessary using the recommended fluid type (DOT 3 or DOT 4).
Inspect brake pads and rotors for wear; replace if they are below the manufacturer's specifications.

6. Reconnect Battery and Test Drive

Reconnect the negative battery terminal.
Start the vehicle and check if the traction control light is still illuminated.
Conduct a test drive to ensure the traction control system is functioning correctly.
