Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the ignition is off.
Disconnect the battery to prevent electrical shock.

2. Remove the Wheel

Tools Required: Socket set, lug wrench
Loosen the lug nuts on the left front wheel.
Raise the vehicle with a jack and secure it with jack stands.
Remove the lug nuts and take off the wheel.

3. Inspect and Replace Wheel Speed Sensor

Tools Required: Torque wrench, socket set, wire cutters (if necessary)
Locate the left front wheel speed sensor mounted on the wheel hub.
Disconnect the sensor's electrical connector.
Remove the mounting bolt securing the sensor to the hub.
Carefully pull the sensor out from the hub assembly.
If the sensor is damaged, replace it with a new one, ensuring it is seated properly.

4. Reassemble

Reinstall the sensor bolt and tighten it to the manufacturer's specified torque.
Reconnect the electrical connector to the new sensor.
Reinstall the left front wheel, hand-tightening the lug nuts.
Lower the vehicle from the jack stands and tighten the lug nuts to the specified torque.

5. Reconnect Battery and Clear Codes

Reconnect the battery terminals.
Use the OBD-II scanner to clear the C0035 code from the system.
Perform a test drive to ensure the issue is resolved.
