How do I clear the Check Engine Light?

You can clear the Check Engine Light using an OBD-II scan tool by connecting it to the DLC and selecting "Clear Codes" or "Erase DTCs." Disconnecting the battery for 15-30 minutes may also reset it, though this clears all learned parameters and radio presets. Important: Clearing codes without fixing the underlying problem will cause the light to return after a few drive cycles when the OBD-II system re-detects the fault. Always diagnose and repair the issue before clearing codes.
