Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery before starting the repair.

2. Inspect and Clean Wheel Speed Sensors

Locate the wheel speed sensors at each wheel hub.
Remove any debris or dirt from the sensor area using a soft cloth.
Check the sensor's electrical connector for corrosion or damage.
If necessary, disconnect and reconnect the sensor to ensure a proper connection.

3. Check and Replace Faulty Components

If diagnostics indicated a faulty wheel speed sensor, replace it:
- Remove the wheel for easier access.
- Unbolt the faulty sensor using the appropriate socket.
- Install the new sensor and torque to manufacturer specifications (usually around 10-15 Nm).
- Reinstall the wheel and lower the vehicle.

4. Reset the Traction Control System

Using the OBD-II scanner, clear any fault codes related to the traction control and ABS systems.
Reconnect the battery and start the vehicle.

5. Test the System

Conduct a test drive under conditions that previously triggered the traction control light.
Monitor the dashboard for any warning lights and ensure the system operates as expected.
