Solution

1. Preparation

Gather tools and parts required for the repair.
Make sure the vehicle is parked on a level surface and turn off the ignition.
Disconnect the battery to ensure safety while working on electrical components.

2. Inspect and Clean Wheel Speed Sensors

Use a socket set to remove the wheel covers if necessary.
Remove the wheels to access the wheel speed sensors.
Inspect each wheel speed sensor for dirt or debris.
Clean the sensors using a soft cloth and appropriate cleaner.
Reinstall the wheels and covers, ensuring they are secured properly.

3. Check Brake Fluid Level

Locate the brake fluid reservoir under the hood.
Check the fluid level against the 'MIN' and 'MAX' markings.
If the fluid is low, add the appropriate brake fluid type (DOT 3 or DOT 4) until it reaches the proper level.

4. Inspect the Traction Control Switch

Locate the traction control switch, usually found on the dashboard or near the gear shifter.
Ensure the switch is functioning correctly by pressing it to toggle the traction control system on and off.
If the switch is faulty, replace it with a new part.

5. Reconnect Battery and Clear Codes

Reconnect the battery terminals securely.
Use the OBD-II scanner to clear any fault codes from the system.
Start the vehicle to check if the traction control light remains illuminated.
