Solution

1. Preparation

Ensure the vehicle is parked on a flat surface and turn off the engine.
Disconnect the battery to avoid any electrical shorts while working on the traction control system.
Gather all necessary tools and replacement parts.

2. Inspect and Clean Wheel Speed Sensors

Locate the wheel speed sensors at each wheel hub.
Disconnect the sensor connectors carefully.
Remove any dirt or debris from the sensor and connector using a soft cloth.
Reconnect the sensors and ensure they are securely fastened.

3. Check Brake System

Inspect the brake fluid reservoir for proper fluid levels; refill if necessary with manufacturer-recommended brake fluid.
Check the brake pads and rotors for wear; replace if they are below the manufacturer's specifications.
If the ABS module has been flagged in error codes, consider performing a reset or replacing the module as per specifications.

4. Test Traction Control Switch

Locate the traction control switch on the dashboard.
Use a multimeter to check for continuity when the switch is pressed.
Replace the switch if it is found to be faulty.

5. Reconnect Battery and Clear Codes

Reconnect the battery.
Use the OBD-II scanner to clear any existing error codes.
Start the vehicle and verify that the traction control light is no longer illuminated.
