Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, socket set, torque wrench, wire stripper/crimper, dielectric grease
Disconnect the vehicle battery to prevent electrical shorts or shocks.

2. Inspect and Replace Wheel Speed Sensor

Locate the Wheel Speed Sensor:
- Refer to the vehicle repair manual to find the exact location of the wheel speed sensor for the affected wheel.
Remove the Wheel:
- Loosen the lug nuts using a socket set and jack up the vehicle.
- Remove the wheel to access the wheel speed sensor.
Disconnect the Sensor:
- Unplug the electrical connector from the wheel speed sensor, ensuring not to damage the connector.
Remove the Sensor:
- Use the appropriate socket to remove any bolts securing the wheel speed sensor to the hub.
- Carefully pull the sensor out of its mounting location.
Install New Sensor:
- Apply dielectric grease to the new sensor’s connector to prevent corrosion.
- Insert the new wheel speed sensor into the mounting location and secure it with bolts to the specified torque values (refer to repair manual for exact torque specification).
- Reconnect the electrical connector.

3. Reassembly

Reinstall the Wheel:
- Put the wheel back on and hand-tighten the lug nuts.
- Lower the vehicle and then tighten the lug nuts to the manufacturer's specifications using a torque wrench.
Reconnect Battery:
- Reconnect the vehicle battery and ensure all connections are secure.

4. Clear Codes and Test

Clear the Codes:
- Use the OBD-II scanner to clear the C0035 ABS code from the system.
Test Drive the Vehicle:
- Perform a test drive to ensure the ABS system functions correctly and that the warning lights do not reappear.
