Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the negative battery terminal to prevent electrical shock.

2. Replace Faulty Wheel Speed Sensor

Tools Required: Socket set, screwdriver, multimeter, torque wrench.
Locate the wheel speed sensor that corresponds to the error codes retrieved.
Remove the wheel and tire to access the sensor.
Disconnect the wiring harness from the sensor.
Unbolt the old sensor using the socket set and remove it from the hub.
Install the new wheel speed sensor in reverse order, ensuring it is properly seated.
Torque the sensor bolt to the manufacturer's specifications (usually around 7-10 ft-lbs).

3. Clear Error Codes

Reconnect the negative battery terminal.
Use the OBD-II scanner to clear any diagnostic trouble codes (DTCs).
Start the vehicle and check if the traction control light remains off.

4. Test Drive

Take the vehicle for a test drive to ensure that the traction control system is functioning correctly.
Monitor for any re-illuminations of the traction control light.
