On Board Diagnostics OBD-II

OBD II (On Board Diagnostics Second Generation) is a system in your car that monitors how well the engine and other parts are working, and it can give you a warning if something goes wrong.

Standard on gasoline American Cars since 1996 and diesel since 1997 and initially implented as a way to monitor emissions, OBD has now evolved into a full fault reporting system for modern vehicles.
