On-Board Diagnostics, Second Generation (OBD-II) is a set of standards for implementing a computer-based system to control emissions from vehicles. It was first introduced in the United States in 1994, and became a requirement on all 1996 and newer US vehicles. Other countries, including Canada, parts of the European Union, Japan, Australia and Brazil adopted similar legislation. A large portion of the modern vehicle fleet supports OBD-II or one of its regional flavours.
Among other things, OBD-II requires that each compliant vehicle be equipped with a standard diagnostic connector and describes a standard way of communicating with the vehicle’s computer, also known as the ECU (electronic control unit). A wealth of information can be obtained by tapping into the OBD bus, including the status of the malfunction indicator light, diagnostic trouble codes, inspection and maintenance information, freeze frames, VIN, hundreds of real-time parameters, and more.
Made by ScanTool.net, the STN1117 is an OBD to UART interpreter that can be used to convert messages between any of the OBD-II protocols currently in use, and UART. It is fully compatible with the de facto industry standard ELM327 command set. Based on a 16-bit processor core, ScanTool.net claims it offers more features and better performance than any other ELM327 compatible IC.
The STN1170 combines the entire STN1110 (multiprotocol OBD-II) feature set with single wire CAN (SW-CAN) and medium speed CAN (MS-CAN) protocols in a single 44-pin IC. SW-CAN protocol support allows a device to access, monitor and issue commands on vehicles utilising GM’s proprietary CAN network. Similarly, MS-CAN provides access to Ford’s proprietary CAN network on supporting models.
