Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the negative terminal of the battery for safety.

2. Inspect Wheel Speed Sensors

Remove the wheel cover or wheel if necessary for access.
Disconnect the wheel speed sensor electrical connector.
Clean the sensor and the mounting area with a soft cloth or brake cleaner.
Inspect the sensor for any physical damage and replace if necessary.

3. Check Brake Fluid Level

Open the hood and locate the brake fluid reservoir.
Check the fluid level against the markings on the reservoir; refill with the recommended brake fluid if low.
Inspect for any signs of leakage around brake lines.

4. Test Traction Control Switch

Locate the traction control switch on the dashboard.
Use a multimeter to test the switch for continuity; it should show continuity when pressed.
Replace the switch if it does not function properly.

5. Reconnect Battery and Clear Codes

Reconnect the negative terminal of the battery.
Use the OBD-II scanner to clear any stored trouble codes related to the traction control system.
Start the vehicle to check if the traction control light is still illuminated.
