Plug the OBD-II scanner into the vehicle's diagnostic port, located under the dashboard near the steering column.
Turn the ignition key to the "ON" position (do not start the engine).
Follow the scanner's prompts to read and clear the trouble codes.
Select the option to erase faults, which will reset the check engine light.
