- Disconnect the electrical connectors and any attached hoses.
- Unbolt the module from its mounting bracket.
Wheel Speed Sensors: Inspect each sensor.
- Remove the sensor from the hub assembly.
- Clean the sensor tip with a soft cloth and inspect for damage.
- Test the sensor with a multimeter for continuity and proper voltage output.

3. Replace Faulty Components

If any wheel speed sensors are faulty, replace them with new OEM or quality aftermarket parts.
If the ABS module is diagnosed as defective, replace it.
- Ensure the new module is correctly coded to the vehicle’s specifications if necessary.

4. Reinstallation

Reinstall the ABS module and ensure all connections are secure.
Reinstall the wheel speed sensors and ensure they are seated properly.
Reconnect the battery and check the ABS fuse and relay for proper installation.

5. Testing
