Solution

1. Preparation

Gather necessary tools and components.
Ensure the vehicle is parked on a level surface and secure it with wheel chocks.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Inspect and Replace Wheel Speed Sensor

Locate the Right Front Wheel Speed Sensor
- Remove the right front wheel using a socket set.
- Locate the wheel speed sensor mounted on the hub assembly.
Remove the Wheel Speed Sensor
- Disconnect the electrical connector from the wheel speed sensor.
- Remove the sensor mounting bolt using the appropriate socket.
- Carefully pull the sensor out of the hub assembly.
Install New Wheel Speed Sensor
- Apply a small amount of anti-seize compound to the sensor's mounting area (if recommended).
- Insert the new wheel speed sensor into the hub assembly and secure it with the mounting bolt.
- Torque the bolt to the manufacturer's specified value (usually around 8-10 ft-lbs).
Reconnect the Electrical Connector
- Ensure the connector is clean and securely attached to the new sensor.

3. Clear Codes and Test Drive

Reconnect the Battery
- Reattach the negative battery terminal and tighten securely.
Clear the Diagnostic Codes
- Use the OBD-II scanner to clear the C0031 code from the vehicle's computer.
Test Drive the Vehicle
- Drive the vehicle at various speeds and conditions to verify proper ABS and traction control operation.
