Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is turned off.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Inspect Wheel Speed Sensors

Remove the wheel to access the wheel speed sensor.
Clean the sensor and surrounding area to remove any debris.
Check the wiring for any signs of wear or damage.
Reinstall the wheel and tighten lug nuts to the manufacturer's specifications.

3. Check Brake Fluid Level

Locate the brake fluid reservoir under the hood.
Ensure the fluid is at the recommended level; top off with manufacturer-recommended brake fluid if necessary.
Reconnect the negative battery terminal.

4. Test Traction Control Switch

Locate the traction control switch on the dashboard.
Use a multimeter to check for continuity when the switch is pressed.
If faulty, replace with a new switch by removing the panel and disconnecting the wiring harness.

5. Clear Error Codes

Reconnect the OBD-II scanner to the vehicle's diagnostic port.
Clear any stored error codes from the traction control system.
Test drive the vehicle to see if the traction control light returns.
