Solution

1. Preparation

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

2. Scan and Clear Fault Codes

Use the OBD-II scanner to retrieve and document any fault codes.
Clear the codes and check if the traction control light reappears after a test drive.

3. Inspect Wheel Speed Sensors

Locate the wheel speed sensors at each wheel hub.
Disconnect the electrical connector for each sensor.
Clean the sensor and its mounting area to remove any debris or corrosion.
Reconnect the sensors and ensure they are securely fastened.

4. Check ABS Module Connections

Locate the ABS module, usually near the brake master cylinder.
Inspect the wiring harness and connectors for any signs of damage or loose connections.
If necessary, clean the connectors with electrical contact cleaner.

5. Brake Pedal Switch Inspection

Check the brake pedal switch located above the brake pedal.
Ensure it is functioning correctly; if faulty, replace the switch.

6. Tire Inspection

Inspect all four tires for proper inflation and adequate tread depth.
Replace any tires that are worn or damaged.

7. Reconnect Battery and Test Drive

Reconnect the battery.
Perform a test drive to ensure the traction control light does not turn on again.
