Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is on a flat surface and the ignition is off.
Disconnect the battery to prevent electrical shock during repairs.

2. Inspect Wheel Speed Sensors

Tools Required: Socket set, multimeter.
Remove the wheel to access the wheel speed sensor.
Disconnect the sensor wiring harness.
Use a multimeter to check the sensor's resistance; it should typically fall within the manufacturer's specified range.
Clean the sensor and the mounting area to remove any debris.
Reconnect the sensor and wheel, ensuring proper torque on lug nuts.

3. Check Brake System Components

Inspect the ABS module for any leaks or damage.
Ensure brake fluid levels are adequate and there are no leaks in the brake lines.
If the ABS module is faulty, consider replacing it with a new unit, following the manufacturer's guidelines for installation.

4. Test the Traction Control Switch

Tools Required: Multimeter.
Locate the traction control switch on the dashboard.
Use a multimeter to test the switch functionality; it should show continuity when pressed.
If the switch is faulty, replace it with a new one.

5. Inspect Wiring and Connectors

Visually inspect the wiring harnesses connected to the traction control system for fraying or corrosion.
Use a multimeter to check for continuity in the wires.
Repair or replace any damaged wiring or connectors.

6. Reconnect Battery and Clear Codes

Reconnect the battery terminals securely.
Use the OBD-II scanner to clear any stored fault codes from the vehicle’s computer.
Start the vehicle and check if the traction control light remains off.
