1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the negative battery terminal to reset the ECU if required.

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.
Follow the scanner’s instructions to retrieve and note any error codes.

3. Inspect the Gas Cap

Remove the gas cap and visually inspect for cracks or damage.
Reinstall the gas cap and ensure it clicks securely into place.

4. Clear Codes

If error codes are present that do not indicate immediate repair needs, clear the codes using the OBD-II scanner.
Reconnect the negative battery terminal once codes are cleared.

5. Monitor the Vehicle

Start the engine and monitor for any return of the check engine light.
Drive the vehicle for a short distance to see if the light reappears.
