Solution

1. Preparation

Ensure the vehicle is parked on a level surface and the engine is turned off.
Gather necessary tools: OBD-II scanner, vehicle manual.

2. Connect OBD-II Scanner

Locate the OBD-II port (under the dashboard near the driver's seat).
Plug the OBD-II scanner into the port and turn the ignition key to the "On" position without starting the engine.

3. Retrieve and Clear Codes

Follow the scanner’s instructions to read diagnostic trouble codes (DTCs).
Document any codes that appear for future reference.
Use the scanner's function to clear the codes. This usually involves selecting "Erase Codes" or a similar option.

4. Test Drive

Turn off the ignition and disconnect the OBD-II scanner.
Start the engine and perform a test drive for at least 10-15 minutes to monitor if the check engine light reappears.

5. Monitor for Recurrence

After the test drive, check again to see if the check engine light remains off.
If it does illuminate again, further diagnostic work will be necessary.
