Solution

1. Preparation

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

2. Use an OBD-II Scanner

Locate the OBD-II port, typically found under the dashboard near the steering column.
Plug the OBD-II scanner into the port.
Turn the ignition to the "On" position without starting the engine.
Follow the scanner's instructions to access the Diagnostic Trouble Codes (DTCs).
Write down any codes for reference.

3. Clear the Codes

On the scanner menu, select the option to "Clear Codes" or "Erase Codes."
Confirm the action when prompted.
Wait for the scanner to indicate that the codes have been successfully cleared.

4. Verify the Reset

Turn off the ignition and unplug the OBD-II scanner.
Start the engine and observe if the check engine light remains off.
If the light returns shortly after, further diagnostics may be required.
