Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, socket set, torque wrench, wire stripper, and electrical tape.
Safely lift and support the vehicle on jack stands.
Disconnect the battery to prevent any electrical shorts.

2. Inspect and Replace Wheel Speed Sensor

Sub-steps:
1. Remove the left front wheel using a socket set.
2. Locate the wheel speed sensor mounted on the wheel hub.
3. Disconnect the sensor's electrical connector.
4. Remove the sensor from its mounting with the appropriate socket.
5. Install the new wheel speed sensor, ensuring it is securely seated.
6. Reconnect the electrical connector to the sensor.
7. Reinstall the wheel and tighten the lug nuts to the manufacturer’s torque specification.

3. Repair Wiring (if applicable)

Sub-steps:
1. If damaged wiring is found, carefully cut away the damaged section.
2. Strip the ends of the wires to prepare for splicing.
3. Use appropriate connectors or solder the wires together securely.
4. Insulate the repaired area with electrical tape to prevent moisture ingress.

4. Reconnect Battery and Clear Codes

Reconnect the battery terminals.
Use the OBD-II scanner to clear the C0035 code and any other related codes.
Ensure that all connections are secure.
