Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the vehicle battery to prevent electrical shorts.
Ensure the vehicle is on a flat surface and secure it with wheel chocks.

2. Inspect and Clean Wheel Speed Sensors

Remove the wheels to access the ABS wheel speed sensors.
Use a clean cloth to wipe any dirt or debris from the sensors.
Inspect the wiring harness for fraying or damage.
Reinstall the wheels and lower the vehicle.

3. Check Brake Fluid and System

Remove the brake fluid reservoir cap and check fluid level; top off with the recommended brake fluid if low.
Inspect brake lines for signs of leakage or wear.
If leaks are found, replace the affected components as necessary.

4. Test ABS Module and Pump

Reconnect the battery and turn the ignition to the "ON" position without starting the engine.
Listen for the ABS pump operation; it should activate briefly.
If the pump does not operate, test the relay and replace if faulty.

5. Clear Error Codes

Use the OBD-II scanner to clear any ABS fault codes.
Conduct a road test to ensure the ABS system is functioning properly.
