Solution

1. Preparation

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

2. Inspect and Clean the Wheel Speed Sensor

Locate the left front wheel speed sensor, typically mounted near the brake rotor.
Remove any debris or dirt around the sensor and the sensor ring.
Carefully disconnect the sensor harness.

3. Replace the Wheel Speed Sensor (if faulty)

Tools Required: Socket set, torque wrench, multimeter
Remove the mounting bolt(s) securing the wheel speed sensor using the socket set.
Pull the sensor out gently from its housing.
Insert the new wheel speed sensor into the housing and secure it with the mounting bolt(s) at the manufacturer’s specified torque.
Reconnect the sensor harness securely.

4. Repair Wiring (if damaged)

If damaged wiring is found, splice in new wire and connectors as needed.
Ensure all connections are secure and insulated properly to prevent shorts.

5. Reconnect Battery and Test

Reconnect the negative battery terminal.
Start the vehicle and perform a test drive to ensure the ABS and traction control lights do not reappear and the system operates correctly.
