Solution

1. Preparation

Gather necessary tools: OBD-II scanner, safety glasses, and gloves.
Ensure the vehicle is parked on a level surface and the ignition is off.

2. Inspect Brake Fluid

Open the hood and locate the brake fluid reservoir.
Check the fluid level against the minimum and maximum marks.
If low, top up with the manufacturer-recommended brake fluid type (usually DOT 3 or DOT 4).
Close the reservoir cap securely.

3. Check ABS Fuse

Locate the fuse box (usually found in the engine compartment or under the dashboard).
Identify the ABS fuse using the diagram on the fuse box cover.
Remove the fuse and inspect it for continuity. Replace it if blown.

4. Use OBD-II Scanner to Clear Codes

Connect the OBD-II scanner to the vehicle's diagnostic port (usually located under the dashboard).
Turn the ignition to the ON position without starting the engine.
Navigate to the ABS module on the scanner and read any stored fault codes.
Follow the scanner instructions to clear the codes.

5. Test Drive

Start the vehicle and take it for a test drive.
Monitor the dashboard for the ABS light. If it does not re-illuminate, the reset was successful.
