$3.15
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.
ELM327 Bluetooth CAN-BUS scan tool supports OBD-II protocols. It is used to read & diagnose trouble codes, clear trouble codes and detect fuel pressure and so on.
The ELM327 Bluetooth adapter gives you the opportunity to “spy” on your car wirelessly. Convert your PC, PDA, Mobile to a diagnostic tool and monitor all critical information of the car’s ECU. The Elm327 Bluetooth is an adapter that connects to the car’s network and then creates a virtual cable between the adapter and the PC that it is connected. With the help of various open source application for the Elm327, you can have a digital gauge or an advanced. diagnostic system and a powerful performance measurement toll in your screen.
