Solution

1. Preparation

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

2. Scan for Error Codes

Connect the OBD-II scanner to the vehicle's OBD-II port, usually located under the dashboard near the steering column.
Turn the ignition key to the "ON" position without starting the engine.
Follow the scanner's instructions to read and record any error codes.

3. Clear Error Codes

After diagnosing, navigate to the "Erase Codes" option on the OBD-II scanner.
Confirm the action to clear the stored error codes.
Wait for the scanner to indicate that the codes have been successfully erased.

4. Test Drive

Start the engine and allow it to idle for a few minutes.
Take the vehicle for a short test drive to ensure that the check engine light remains off and no new codes appear.

5. Monitor Vehicle Performance

After the test drive, check the OBD-II scanner once more to ensure no fault codes have returned.
