Solution

1. Preparation

Gather required tools and parts.
Ensure the vehicle is parked on a level surface, and the ignition is turned off.
Disconnect the negative battery terminal for safety.

2. Check and Clean Wheel Speed Sensors

Required Tools: Socket set, cleaning brush, brake cleaner.
Remove the wheel on the affected side to gain access to the wheel speed sensor.
Clean the sensor using brake cleaner and a brush to remove any debris or metal shavings.
Reinstall the wheel and repeat for the opposite side if necessary.

3. Inspect Brake Fluid and System

Check the brake fluid reservoir and ensure it is filled to the correct level.
Inspect brake lines for leaks or damage. If leaks are found, replace the damaged sections.
If fluid level is low due to a leak, top off with the manufacturer-recommended brake fluid.

4. Test ABS Module

Reconnect the negative battery terminal.
Use the OBD-II scanner to clear any existing trouble codes.
Test drive the vehicle to see if the traction control light reappears. If it does, further diagnostics of the ABS module may be necessary, which may involve replacing the module if found defective.

5. Reconnect Battery and Final Check

Ensure all components are reinstalled properly.
Reconnect the negative battery terminal.
Start the vehicle and check if the traction control light remains off after a short drive.
