Understanding OBD Systems and Your Car
OBD, which stands for On-Board Diagnostics, refers to a standardized system and port found in most modern cars. This port, often resembling an older style TV SCART connector, acts as the interface for diagnostic tools like the best car fault code scanner. Since January 1, 2001, all petrol passenger cars sold in Europe have been equipped with OBD ports, with diesel vehicles following suit from 2004. This 16-pin connector is known as OBD2 in regions outside Europe and EOBD (European On-Board Diagnostics) within Europe, essentially referring to the same standard.
