Solution

1. Preparation

Gather necessary tools and ensure the vehicle is in a safe and well-ventilated area.
Connect the OBD-II scanner to the vehicle's diagnostic port, typically located under the dashboard near the driver's seat.

2. Scan for Error Codes

Turn the ignition to the "ON" position without starting the engine.
Follow the scanner's prompts to begin scanning the vehicle’s computer for diagnostic trouble codes (DTCs).
Note any codes displayed; these will help identify any issues that may need addressing.

3. Address Underlying Issues

If any specific codes are present, refer to service manuals or repair guides to resolve the issues (e.g., replacing a faulty oxygen sensor).
After repairs are completed, ensure all connections are secure and that there are no leaks or electrical issues.

4. Clear Error Codes

With the OBD-II scanner still connected, navigate to the option to clear or erase the error codes.
Follow the prompts on the scanner to confirm the action.
Wait for the scanner to confirm that the codes have been cleared.

5. Verify Reset

Turn off the ignition and disconnect the OBD-II scanner.
Start the engine and observe if the check engine light remains off after a short period.
