Solution

1. Preparation

Ensure the vehicle is parked on a level surface and the ignition is turned off.
Gather tools: OBD-II scanner, vehicle owner's manual (for reference), and possibly a wrench set.

2. Connect the OBD-II Scanner

Locate the OBD-II port, typically found under the dashboard near the driver's seat.
Plug the OBD-II scanner into the port securely.
Turn the ignition to the "On" position without starting the engine.

3. Read and Clear Codes

Follow the instructions on the OBD-II scanner to read the diagnostic trouble codes (DTCs).
After noting the codes, select the option to clear or erase the codes.
Confirm the action when prompted; the scanner should indicate that codes have been cleared.

4. Disconnect the Scanner

Turn off the ignition before unplugging the OBD-II scanner from the port.
Store the scanner properly for future use.

5. Test Drive

Start the engine and allow it to idle for a few minutes.
Take the vehicle for a short test drive to ensure the check engine light does not reappear.
