Solution

1. Preparation

Gather tools and parts needed for the repair.
Disconnect the vehicle battery by removing the negative terminal.
Ensure the vehicle is on a flat surface and use wheel chocks for safety.

2. Retrieve Error Codes

Connect the OBD-II scanner to the vehicle's diagnostic port and turn the ignition to the "ON" position without starting the engine.
Record any error codes related to the ABS and note their descriptions for further investigation.

3. Inspect ABS Sensors

Raise the vehicle using a jack and securely place jack stands.
Remove the wheels to access the ABS sensors.
Clean the sensor area and check for any dirt or debris.
Ensure the sensor is firmly connected and the wiring harness is intact.

4. Check Brake Fluid

Open the hood and locate the brake fluid reservoir.
Inspect the brake fluid level; it should be between the "MIN" and "MAX" marks.
If low, top off with the recommended brake fluid type (DOT 3 or DOT 4).
If the fluid is dirty or contaminated, perform a brake fluid flush.

5. Inspect ABS Module and Pump

Locate the ABS module and pump under the hood.
Check for any visible leaks or damage to the unit.
If necessary, replace the ABS module or pump based on diagnostic findings.

6. Clear Error Codes

After repairs, use the OBD-II scanner to clear any stored error codes.
Reconnect the battery and start the vehicle to check if the ABS light is off.
