Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, socket set, torque wrench, wire brush or electrical contact cleaner.
Ensure the vehicle is parked on a level surface and the ignition is turned off before beginning repairs.

2. Remove the Wheel

Loosen the lug nuts on the front left wheel using a socket set.
Raise the vehicle using a jack and secure it with jack stands.
Remove the lug nuts and take off the wheel.

3. Replace Wheel Speed Sensor

Locate the front left wheel speed sensor on the wheel hub.
Disconnect the sensor's electrical connector.
Remove the mounting bolt(s) securing the sensor to the hub (typically requires a socket or wrench).
Carefully extract the old sensor from its housing.
Install the new sensor by reversing the removal steps.
- Sub-steps:
  - Apply a small amount of anti-seize compound to the sensor's threads (if applicable).
  - Tighten the mounting bolt(s) to the manufacturer's specified torque (refer to the service manual).
  - Reconnect the electrical connector ensuring it clicks into place.

4. Reassemble and Test

Reinstall the wheel and tighten the lug nuts in a crisscross pattern to ensure even pressure.
Lower the vehicle back to the ground.
Reconnect the battery (if disconnected) and use the OBD-II scanner to clear the C0030 code.
Perform a test drive to verify that the ABS and traction control warning lights are off and the system is functioning correctly.
