The first generation of On-Board Diagnostics (called OBD I) was
developed by the California Air Resources Board (CARB) and
implemented in 1988 to monitor some of the emission control
components on vehicles. As technology evolved and the desire to
improve the On-Board Diagnostic system increased, a new generation
of On-Board Diagnostic system was developed. This second
generation of On-Board Diagnostic regulations is called "OBD II".
