Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery terminal to ensure safety during repairs.

2. Inspect and Replace Wheel Speed Sensor

Locate the Left Front Wheel Speed Sensor
- Raise the vehicle using a jack and secure it with jack stands.
- Remove the left front wheel to access the wheel speed sensor.
Remove the Old Wheel Speed Sensor
- Disconnect the electrical connector from the wheel speed sensor.
- Remove the retaining bolt(s) securing the sensor to the hub assembly.
- Carefully pull the sensor out of its mounting location.
Install the New Wheel Speed Sensor
- Lubricate the O-ring of the new wheel speed sensor with a small amount of grease.
- Insert the new sensor into the hub assembly.
- Secure it with the retaining bolt(s) to the specified torque (typically around 10-15 Nm).
- Reconnect the electrical connector to the new sensor.

3. Reassemble and Test

Reinstall the Wheel
- Place the wheel back onto the hub and hand-tighten the lug nuts.
- Lower the vehicle and torque the lug nuts to the manufacturer's specifications (usually around 100-120 Nm).
Reconnect Battery
- Reconnect the negative battery terminal.
Clear Codes and Test Drive
- Use the OBD-II scanner to clear the C0035 code.
- Take the vehicle for a test drive to verify that the ABS and traction control systems are functioning correctly.
