Solution

1. Preparation

Gather necessary tools and safety equipment.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Disconnect the battery to prevent electrical shorts.

2. Scan for Error Codes

Connect the OBD-II scanner to the vehicle’s diagnostic port.
Turn the ignition to the "ON" position without starting the engine.
Record any ABS-related trouble codes for further investigation.

3. Inspect and Clean ABS Sensors

Lift the vehicle and secure it on jack stands.
Remove the wheel to access the ABS sensor.
Check the sensor for dirt, debris, or damage.
Clean the sensor using a soft cloth and brake cleaner.
Reinstall the wheel and lower the vehicle.

4. Check and Replace ABS Fuse

Locate the fuse box (refer to the owner's manual for location).
Identify the ABS fuse and remove it using a fuse puller.
Inspect the fuse for continuity; replace if necessary with the same amperage.

5. Inspect Brake Fluid

Open the master cylinder reservoir cap and check the fluid level.
If low, top off with the recommended brake fluid type (usually DOT 3 or DOT 4).
Inspect for any leaks in the brake lines and rectify as needed.

6. Test ABS Pump

Reconnect the battery and turn the ignition to the "ON" position.
Activate the ABS pump using a scan tool if capable or by performing a brake system self-check.
Listen for the ABS pump operation; if inoperative, consider replacing the ABS module.
