Solution

1. Preparation

Tools Needed: OBD-II scanner, multimeter, socket set, torque wrench.
Safety Precautions: Disconnect the battery before working on electrical systems to prevent short circuits.

2. Address Error Codes

Sub-steps:
1. Clear the error codes using the OBD-II scanner.
2. Test drive the vehicle to see if the traction control light reappears.
3. If the light returns, note the specific error code for further diagnosis.

3. Replace Faulty Wheel Speed Sensors

Sub-steps:
1. Raise the vehicle using a jack and secure it with jack stands.
2. Remove the wheel to access the wheel speed sensor.
3. Disconnect the sensor's electrical connector.
4. Remove the sensor using a socket set.
5. Install the new sensor, ensuring it is torqued to the manufacturer’s specifications (typically around 10 Nm).
6. Reconnect the electrical connector and replace the wheel.

4. Inspect and Repair ABS Module

Sub-steps:
1. Locate the ABS module (usually near the brake master cylinder).
2. Inspect the module for leaks, corrosion, or damage.
3. If necessary, remove the module by disconnecting the brake lines (be sure to have a brake fluid catch container).
4. Replace the module with a new one, ensuring proper alignment and torque specifications.
5. Reconnect the brake lines and bleed the brake system.

5. Reconnect Battery and Test

Sub-steps:
1. Reconnect the battery terminals.
2. Start the vehicle and check if the traction control light is off.
3. Test drive the vehicle under various conditions to ensure proper traction control functionality.
