Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the ignition is off.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Scan and Identify Fault Codes

Connect the OBD-II scanner to the vehicle's diagnostic port.
Turn the ignition to the "ON" position without starting the engine.
Retrieve and note any ABS-related fault codes for reference.

3. Inspect ABS Sensors

Lift the vehicle using a jack and secure it with jack stands.
Remove the wheel to access the ABS sensor.
Inspect the sensor for dirt, damage, or disconnection. Clean or replace as necessary.

4. Check ABS Module and Wiring

Locate the ABS module, usually found near the brake master cylinder.
Inspect wiring connectors for signs of corrosion or loose connections.
If necessary, clean connectors with electrical contact cleaner and reconnect.

5. Brake Fluid Inspection

Check brake fluid reservoir; ensure it is at the proper level and the fluid is clean.
If fluid is low, fill with the manufacturer-recommended brake fluid type.
Inspect brake lines for leaks and replace any damaged sections.

6. Test Drive and Reset

Reconnect the negative battery terminal.
Start the vehicle and check if the ABS light is still illuminated.
If the light is off, take the vehicle for a test drive to verify the ABS system functions correctly.
If the light remains on, use the OBD-II scanner to clear any fault codes.
