Solution

1. Preparation

Gather tools: OBD-II scanner, socket set, multimeter, brake fluid, cleaning supplies.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.

2. Retrieve Fault Codes

Connect the OBD-II scanner to the diagnostic port.
Turn the ignition to the ON position without starting the engine.
Follow the scanner prompts to read and record ABS fault codes.

3. Clear Fault Codes

With the OBD-II scanner still connected, navigate to the option to clear or reset fault codes.
Confirm the action and wait for the scanner to process the reset.
Disconnect the OBD-II scanner once completed.

4. Inspect and Clean ABS Sensors

Remove the wheel covering the ABS sensor.
Clean any dirt or debris from the ABS sensor and the tone ring using brake cleaner.
Reinstall the wheel and repeat for each wheel as needed.

5. Check ABS Fuse and Wiring

Locate the ABS fuse in the fuse box (refer to the owner's manual for location).
Use a multimeter to check for continuity in the fuse. Replace if necessary.
Inspect ABS wiring for signs of wear or damage and repair as needed.

6. Final Steps

Refill the brake fluid if the level is low, using the manufacturer's recommended type.
Start the vehicle and check if the ABS light remains off.
