Solution

1. Preparation

Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery to prevent any electrical shorts.

2. Inspect Wheel Speed Sensors

Remove the wheel covers or tires as necessary for better access.
Locate and visually inspect each wheel speed sensor for damage or dirt.
Clean the sensors with a soft cloth and suitable cleaner, ensuring no debris is left.
Reconnect any loose connectors and ensure they are securely fastened.

3. Inspect ABS Module and Brake System

Locate the ABS module under the hood or near the brake master cylinder.
Check all wiring harnesses for wear or disconnection.
If any faults in the brake system are detected, repair or replace affected components (e.g., brake fluid level, brake pads).
Reconnect the battery after inspection.

4. Test Traction Control Switch

Locate the traction control button on the dashboard.
Test the switch for functionality using a multimeter; it should show continuity when pressed.
If defective, replace the traction control switch.

5. Reconnect Battery and Clear Codes

Reconnect the battery terminals, ensuring a secure connection.
Use the OBD-II scanner to clear any existing error codes.
Start the vehicle and observe whether the traction control light remains illuminated.
