Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a flat surface and the ignition is turned off.
Disconnect the negative terminal of the battery to prevent electrical shorts.

2. Inspect and Clean ABS Sensors

Locate the ABS wheel speed sensors at each wheel hub.
Carefully remove any dirt or debris from the sensor and the mounting area using a clean cloth.
Reconnect any loose connectors and ensure they are secure.

3. Replace Faulty Components

If the diagnostic scan indicated a specific ABS sensor fault, replace the affected wheel speed sensor:
- Tools Required: Socket set, torque wrench
- Steps:
  1. Remove the wheel corresponding to the faulty sensor.
  2. Unbolt the sensor from the wheel hub using the socket set.
  3. Disconnect the sensor connector.
  4. Install the new sensor by reversing the removal steps, ensuring to torque the bolts to manufacturer specifications (typically around 8-10 ft-lbs).

4. Check and Replace ABS Fuse

Locate the ABS fuse in the fuse box (refer to the owner's manual for location).
If the fuse is blown, replace it with a new one of the same amperage.

5. Reconnect Battery and Clear Codes

Reconnect the negative battery terminal securely.
Use the OBD-II scanner to clear any stored ABS trouble codes from the system.

6. Test Drive

Perform a test drive to ensure that the ABS light is no longer illuminated and that the braking system operates correctly.
