Solution

1. Preparation

Gather necessary tools and materials.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the negative terminal of the battery to ensure safety during repairs.

2. Check Wheel Speed Sensors

Locate the wheel speed sensors at each wheel hub.
Clean the sensors and their connectors using electrical contact cleaner.
If any sensors are damaged, replace them using a socket set and torque them to manufacturer specifications.

3. Inspect and Refill Brake Fluid

Locate the brake fluid reservoir and check the fluid level.
If low, refill with the recommended brake fluid type (typically DOT 3 or DOT 4).
Inspect for any leaks in the brake lines or around the master cylinder.

4. Test Traction Control Switch

Locate the traction control switch, typically found on the dashboard or center console.
Use a multimeter to check for continuity when the switch is pressed.
If faulty, replace the switch by prying it out and disconnecting the wiring harness.

5. Reconnect Battery and Clear Codes

Reconnect the negative terminal of the battery.
Use the OBD-II scanner to clear any stored error codes from the system.
Start the vehicle and check if the traction control light remains off.
