    One of the best parts about the scanner is that you can get it in a small size. It is compact enough to fit into your pocket and your car’s dashboard. The scanner usually has a small screen displaying the codes and other information.

    A connector also comes attached with the OBD2 scanner to plug in to the OBD2 port located under the dashboard or some other place in your car. Sometimes you may get separate cables as well. This tool has a modern, sleek look and usually comes in different colors.

    Reset Check Engine Light
