Solution

1. Preparation

Gather the necessary tools and parts for the repair.
Disconnect the battery to prevent electrical shorts or accidental airbag deployment.
Allow the vehicle to cool down if it has been running.

2. Inspect and Clean Wheel Speed Sensors

Locate the wheel speed sensors at each wheel hub.
Using a socket set, remove the bolts securing the sensors.
Clean any debris or dirt from the sensors and mounting areas using a soft brush or cloth.
Reinstall the sensors and secure them with bolts to the manufacturer's torque specifications (typically around 8-10 Nm).

3. Check and Repair Wiring

Visually inspect the wiring harness connected to each wheel speed sensor for fraying or damage.
Use a multimeter to test the continuity of the wires.
Repair or replace any damaged wiring found.

4. Inspect Brake System Components

Check the brake pads, rotors, and calipers for wear and proper function.
If necessary, replace any worn brake components.
Ensure that the brake fluid is at the appropriate level and not contaminated.

5. Reset the Traction Control System

Reconnect the battery and use the OBD-II scanner to clear any stored error codes from the traction control system.
Turn the ignition to the 'ON' position without starting the engine.
Check if the traction control light turns off after the reset.
