OBD-2 is a standardized system that allows vehicles to self-diagnose and report any issues to the driver or mechanic. It was introduced in the mid-1990s and has since become a mandatory feature in all modern vehicles. OBD-2 uses a 16-pin connector to communicate with external devices, such as scan tools or code readers.
