Solution

1. Preparation

Gather necessary tools and equipment: OBD-II scanner, vehicle owner's manual, and a notebook for recording information.
Ensure the vehicle is parked on a level surface and the ignition is turned off.

2. Scan for Error Codes

Connect the OBD-II scanner to the vehicle's diagnostic port, typically located under the dashboard near the steering column.
Turn the ignition to the "On" position (do not start the engine).
Follow the scanner’s instructions to retrieve and display error codes.

3. Clearing the Codes

Once the error codes are displayed, take note of them for future reference.
Use the scanner's function to clear the codes, which will reset the check engine light.
Confirm that the scanner indicates the codes have been cleared successfully.

4. Visual Inspection

Inspect the engine bay for loose or damaged wiring, vacuum leaks, or faulty connectors that may have caused the check engine light to illuminate.
Ensure that all fluid levels are normal and check for any visible leaks.

5. Test Drive

Start the vehicle and allow it to reach operating temperature.
Drive the vehicle under normal conditions for a few miles to ensure the check engine light remains off.
If the check engine light re-illuminates, further diagnosis will be necessary.
