Connect the OBD-II scanner to the vehicle’s diagnostic port.
Turn the ignition to the "ON" position without starting the engine.
Read and record any trouble codes present.

3. Inspect Wheel Speed Sensors

Locate the wheel speed sensors on each wheel hub.
Visually inspect the sensors for physical damage or obstruction.
Clean any dirt or debris from the sensor area.
Test the sensors using a multimeter to ensure proper resistance values.

4. Check Brake Fluid and Lines

Open the hood and locate the brake fluid reservoir.
Check the fluid level; if low, top it up with the recommended brake fluid.
Inspect brake lines for any signs of leaks or damage.

5. Inspect ABS Module

Locate the ABS module; refer to the service manual for the specific location.
Check for any visible corrosion or loose connections.
If necessary, test the ABS module for faults using the OBD-II scanner.
