Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the vehicle's 12V battery to ensure safety during repairs.

2. Inspect and Repair Wiring

Tools Required: Wire strippers, electrical tape, multimeter
Inspect the wiring harness connected to the wheel speed sensor for any visible damage or corrosion.
If any wiring is damaged, carefully strip the insulation and repair the wires using solder or heat shrink tubing.
Secure the repaired wires with electrical tape to prevent exposure to moisture.

3. Replace Wheel Speed Sensor (if necessary)

Tools Required: Socket set, torque wrench, brake cleaner
Locate the wheel speed sensor at the hub assembly; remove the retaining bolts using a socket set.
Carefully detach the sensor from the hub and disconnect the wiring harness.
Install the new wheel speed sensor by reversing the removal steps, ensuring it is properly seated.
Torque the retaining bolts to the manufacturer's specifications (check service manual for exact torque value).
Clean any excess debris or grease around the sensor area before installation.

4. Reconnect Battery and Reset DTC

Reconnect the 12V battery and ensure all connections are secure.
Use the OBD-II scanner to clear the C0035 code from the vehicle's computer.
Perform a short test drive to confirm that the warning lights are off and the system is functioning properly.
