Solution

1. Preparation

Gather tools and materials.
Disconnect the vehicle battery to prevent electrical damage.

Tools Required:

OBD-II scanner
Multimeter
Socket set
Torque wrench
Screwdrivers
Wire strippers and connectors (if repairs are needed)

2. Remove the Right Front Wheel

Loosen the lug nuts on the right front wheel.
Jack up the vehicle using a hydraulic jack and secure it with jack stands.
Remove the lug nuts and take off the wheel.

3. Inspect and Replace the Wheel Speed Sensor

Locate the wheel speed sensor on the right front wheel hub assembly.
Disconnect the electrical connector from the wheel speed sensor.
Unbolt the sensor from its mounting position using a socket wrench.
Inspect the sensor for any physical damage.
If damaged, replace it with a new sensor by reversing the removal steps:
- Install the new sensor and tighten it to the manufacturer's torque specification.
- Reconnect the electrical connector.

4. Reassemble and Test

Reinstall the right front wheel and hand-tighten the lug nuts.
Lower the vehicle and then torque the lug nuts to the manufacturer's specifications.
Reconnect the battery and start the vehicle.
Clear the codes using the OBD-II scanner and take the vehicle for a test drive to verify that the C0030 code does not reappear.
