Locate the ABS wheel speed sensors at each wheel hub.
Remove any dirt or debris from the sensor area using a clean cloth.
Check the sensor wiring for wear or damage, and repair as necessary.
Reconnect the sensors and ensure they are securely mounted.

3. Replace Faulty ABS Components

If diagnostics indicate a faulty ABS control module or wheel speed sensor:
- ABS Control Module Replacement:
  - Disconnect the wiring harness and remove any mounting bolts securing the control module.
  - Install the new ABS control module in reverse order of removal and reconnect the wiring harness.
- Wheel Speed Sensor Replacement:
  - Remove the bolt securing the sensor to the wheel hub.
  - Pull the sensor out and install the new sensor by reversing the removal steps.
