Solution

1. Preparation

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

2. Scan for Trouble Codes

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 ABS trouble codes.
Clear the codes and see if they return after a short drive.

3. Inspect ABS Fuse

Locate the fuse box (usually under the dashboard or hood).
Check the ABS fuse by removing it and inspecting for continuity.
Replace the fuse if it is blown (ensure to use the correct amperage).

4. Check ABS Sensors

Raise the vehicle and secure it with jack stands.
Inspect the ABS sensors at each wheel for dirt, damage, or loose connections.
Clean the sensors with brake cleaner if contaminated.
Reconnect any loose or damaged connectors.

5. Test ABS Pump

Reconnect the battery.
Start the engine and activate the ABS system by pressing the brake pedal firmly.
Listen for the ABS pump operation; it should engage briefly.
If the pump does not engage, it may need to be replaced.

6. Check Brake Fluid

Open the hood and locate the brake fluid reservoir.
Ensure the brake fluid is at the recommended level (between minimum and maximum marks).
If low, top off with the manufacturer-recommended brake fluid type.
