Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, socket set, torque wrench, and wire connectors.
Ensure the vehicle is parked on a flat surface and the ignition is off.

2. Inspect and Repair Wiring

Sub-step 1: Disconnect the negative battery terminal to prevent electrical shorts.
Sub-step 2: Remove the wheel and inspect the wiring harness for the left front wheel speed sensor.
Sub-step 3: Repair or replace any damaged wiring or connectors as necessary.
Tools Required: Wire strippers, soldering iron, heat shrink tubing.

3. Replace Wheel Speed Sensor

Sub-step 1: If the sensor is faulty, locate the wheel speed sensor mounted on the left front hub assembly.
Sub-step 2: Remove the retaining bolt using a socket and ratchet.
Sub-step 3: Carefully pull out the old sensor from the hub.
Sub-step 4: Install the new wheel speed sensor by reversing the removal steps.
Sub-step 5: Torque the retaining bolt to the manufacturer's specifications (typically around 10-15 ft-lbs).

4. Reconnect Battery and Test

Sub-step 1: Reconnect the negative battery terminal.
Sub-step 2: Start the vehicle and use the OBD-II scanner to clear the C0231 error code.
Sub-step 3: Test drive the vehicle to ensure that the ABS light and traction control light do not re-illuminate.
