Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the ignition is off.
Disconnect the battery to prevent any electrical short circuits.

2. Inspect Wheel Speed Sensors

Remove the wheels for better access to the wheel speed sensors.
Inspect the wiring and connectors for any damage or corrosion.
Clean the sensors using electrical contact cleaner.
Reinstall wheels and reconnect the battery.

3. Check Traction Control Switch

Locate the traction control button on the dashboard.
Ensure that it is functioning properly; press it to toggle the traction control on and off.
If the switch is defective, replace it using a trim removal tool to access the button.

4. Inspect Brake System

Check brake fluid level in the reservoir; refill if necessary with DOT 3 or DOT 4 fluid.
Inspect brake lines for leaks or damage.
Test the ABS module by checking for any fault codes related to the ABS system.

5. Tire Inspection

Check tire pressure using a tire pressure gauge; inflate to the recommended PSI.
Inspect tire tread for uneven wear or damage; replace tires if necessary.

6. Reconnect Battery and Clear Codes

Reconnect the battery and turn the ignition to the "ON" position without starting the engine.
Use the OBD-II scanner to clear any stored fault codes.
Start the engine and verify the traction control light is off.
