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 shorts.

2. Inspect and Replace Wheel Speed Sensor

Tools Required: Socket set, multimeter, torque wrench.
Remove the wheel on the left front side using a lug wrench.
Locate the wheel speed sensor on the hub assembly.
Unplug the electrical connector from the sensor.
Remove the mounting bolts securing the sensor; typically, they are torqued to around 7-9 lb-ft.
Pull the old sensor out of the hub and inspect the tone ring for damage.
Install the new wheel speed sensor, ensuring it seats correctly in the hub.
Reattach the electrical connector and secure it properly.

3. Clear Fault Codes and Test Drive

Reconnect the negative battery terminal.
Use the OBD-II scanner to clear any stored fault codes.
Conduct a test drive to ensure proper function of ABS and traction control systems.
