This allows the user to read and clear diagnostic trouble codes (DTCs), as well as view, live data streams from various sensors in the vehicle. Automotive scan tools come in a variety of different shapes and sizes, but most are handheld devices that connect to the vehicle via a cable.

Today, most vehicles on the road are equipped with some form of OBD system, and automotive scan tools have become an essential tool for many professional mechanics and do-it-yourselfers alike.

More advanced automotive scan tools, such as the ones made by Autel and Launch Tech USA, offer a wide range of features and capabilities. These higher-end scanners can be used to read and clear DTCs, as well as view, live data streams from various sensors in the vehicle.
