Solution

1. Preparation

Gather tools and parts required for the repair.
Disconnect the vehicle's battery to ensure safety.
Ensure the vehicle is on a level surface and secure it with wheel chocks.

2. Inspect and Replace Wheel Speed Sensors

Locate the Wheel Speed Sensors: Identify the location of the wheel speed sensors at each wheel hub.
Remove the Wheel:
- Loosen lug nuts using a socket set.
- Lift the vehicle with a jack and secure it on jack stands.
- Remove the wheel.
Disconnect the Sensor:
- Unplug the sensor connector from the wiring harness.
Remove the Sensor:
- Use the appropriate socket or wrench to remove the retaining bolt.
- Pull the sensor out of the hub assembly.
Install New Sensor:
- Insert the new sensor into the hub assembly.
- Secure it with the retaining bolt to the manufacturer's specified torque.
- Reconnect the sensor to the wiring harness.
Reinstall the Wheel:
- Place the wheel back onto the hub.
- Hand-tighten the lug nuts, lower the vehicle, and then torque the lug nuts to the manufacturer's specification.

3. ABS Module and Wiring Inspection

Access the ABS Module:
- Remove any covers or panels obstructing access to the ABS module.
Inspect the Wiring:
- Check for any frayed or damaged wires connected to the ABS module.
Repair or Replace Wires:
- Use electrical tape or heat-shrink tubing to repair any damaged wires, or replace them if necessary.
Test ABS Module:
- Reconnect the battery and use the OBD-II scanner to clear any previous ABS codes.
- Perform a test of the ABS system by driving the vehicle at low speeds and applying the brakes.
