Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface, engage the parking brake, and disconnect the battery to ensure safety.

2. Inspect and Clean Wheel Speed Sensors

Tools Required: Socket set, cleaning brush, brake cleaner
Carefully remove the wheel assembly if necessary to gain access to the wheel speed sensors.
Use brake cleaner and a brush to clean each wheel speed sensor and its mounting area.
Reinstall any components removed and torque to manufacturer specifications.

3. Check and Replace Brake Fluid

Tools Required: Brake fluid, brake bleeder kit
Verify the brake fluid level in the reservoir. If low, fill it to the recommended level with the appropriate fluid type (DOT 3 or DOT 4).
If fluid is contaminated, bleed the brake system using a brake bleeder kit, ensuring all air bubbles are removed.

4. Inspect Traction Control Switch

Tools Required: Screwdriver set
Locate the traction control switch on the dashboard or center console.
Remove the switch and check for any physical damage or electrical faults.
Test the switch with a multimeter to ensure it operates correctly. Replace if faulty.

5. Clear Diagnostic Codes

Tools Required: OBD-II scanner
Reconnect the battery and use the OBD-II scanner to clear any stored diagnostic trouble codes.
Perform a test drive to check if the traction control light remains off and the system functions correctly.
