OBD (abbreviation for On-Board Diagnostic) is an automotive term

OBD (abbreviation for On-Board Diagnostic) is an automotive term, translated in Chinese as "on-board diagnostic system", which refers to the self-diagnosis and reporting functions of vehicles.
At present, most cars and light trucks on the road are equipped with OBD on-board diagnostic systems. In the 1970s and early 1980s, in order to meet the EPA (United States Environmental Protection Agency) exhaust emission standards, automakers began to use electronic means to control engine functions and diagnose engine problems. A new standard OBD-II was proposed in the mid-1990s, which provides almost complete engine control, and also monitors the vehicle's chassis, body and accessory equipment, as well as the vehicle's diagnostic control network.
