Solution

1. Preparation

Gather all necessary tools and parts.
Disconnect the negative battery terminal to prevent any electrical shorts during repair.

2. Remove the Wheel

Tools Required: Jack, jack stands, lug wrench.
Raise the vehicle using the jack and securely place it on jack stands.
Remove the lug nuts using a lug wrench and take off the left front wheel.

3. Inspect and Replace Wheel Speed Sensor

Tools Required: Socket set, torque wrench.
Locate the wheel speed sensor mounted near the wheel hub.
Disconnect the electrical connector from the wheel speed sensor.
Remove the mounting bolt(s) securing the wheel speed sensor to the hub using the socket set.
Take out the old wheel speed sensor and inspect the mounting area for debris.
Install the new wheel speed sensor in the reverse order, ensuring it is properly seated and tightened to the manufacturer's torque specification.

4. Reassemble and Reconnect

Reconnect the electrical connector to the new wheel speed sensor.
Reinstall the left front wheel, tightening the lug nuts in a star pattern to the specified torque value.
Lower the vehicle from the jack stands.

5. Clear Codes and Test

Tools Required: OBD-II scanner.
Reconnect the negative battery terminal.
Use the OBD-II scanner to clear the C0031 code from the vehicle's computer.
Perform a test drive to ensure that the ABS and traction control lights are no longer illuminated.
