The OBD (On-Board Diagnostic) system regulation has been established to clean the atmosphere. In this regulation, auto manufacturers are obliged to equip their vehicles with a self-diagnosis device (On-board Self Diagnostic System) which monitors the vehicle’s emission-related components and an alarm device (Malfunction Indi­ cator Light) which warns the driver of problems as they occur in the vehicle.

The OBD regulation prohibits the selling of vehicles that do not meet the regulation, carries out an emission survey on vehicles being used, and requires recalling of vehicles that do not satisfy the regulation.

The OBD regulation consists of two generations:

• First generation (OBD-I) approved by the State of California in 1985

• Second generation (OBD-II) revised from OBD-I with new regulation items added
