OBD to UART interpreter chips designed to provide bi-directional half-duplex communication with the vehicle's On-Board Diagnostic system (OBD-II). It supports all legislated OBD-II protocols, as well as two proprietary networks: GM Single Wire CAN (GMLAN), and Ford Medium Speed CAN (MS CAN). 

   A lot of information can be obtained by accessing the OBD bus, including the status of the OBD. Mil, DTC, I / M information, freeze frame, VIN, hundreds of real-time parameters, etc. The interpreter is fully compatible with the ELM327 command set that has become the industry standard. Users can also use more powerful VT instructions to connect with vehicle ECU more conveniently, providing more functions and better performance than other compatible ELM327 chip, and better cost performance.
