Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a flat surface and securely parked with the engine off.
Disconnect the battery to prevent electrical shorts.

2. Retrieve and Interpret Diagnostic Codes

Connect the OBD-II scanner to the vehicle's diagnostic port.
Turn the ignition to the "ON" position without starting the engine.
Read the ABS codes and take note for troubleshooting.

3. Inspect ABS Wheel Speed Sensors

Locate the wheel speed sensors at each wheel hub.
Remove any dirt or debris obstructing the sensor.
Disconnect the sensor wiring harness and check for continuity using a multimeter.
Replace any damaged sensors.

4. Check ABS Module and Wiring

Visually inspect the ABS module for any signs of damage or corrosion.
Check all wiring connections and harnesses leading to the ABS module.
Repair or replace any damaged wiring or connectors.

5. Examine Brake Fluid

Open the master cylinder cap and check the brake fluid level.
If low, top off with the recommended brake fluid type (DOT 3 or DOT 4).
If the fluid is contaminated, perform a brake fluid flush.

6. Test ABS Pump

Reconnect the battery and turn the ignition to the "ON" position.
Listen for the ABS pump operation when the vehicle is started.
If the pump is silent, further diagnostics may be required, indicating a potential pump failure.
