ELM327 OBD2 V2.1 Bluetooth Interface Auto Car Diagnostic Scanner an on-Board Diagnostics, or OBD, in an automotive context, is a generic term referring to a vehicle’s self-diagnostic and reporting capability. OBD systems give the vehicle owner or a repair technician access to the state of health information for various vehicle sub-systems.
The amount of diagnostic information available via OBD has varied widely since the introduction in the early 1980s of on-board vehicle computers, which made OBD possible. Early instances of OBD would simply illuminate a malfunction indicator light, or MIL, if a problem was detected—but would not provide any information as to the nature of the problem.
Modern OBD implementations use a standardized digital communications port to provide realtime data in addition to a standardized series of diagnostic trouble codes, or DTCs, which allow one to rapidly identify and remedy malfunctions within the vehicle.
