  • List Of Programming Resources

    I know there are several people working on custom interfaces for their carpc's. I wanted to start a list of resources that are available for writing software to interface with OBD-II.

    This is a good pdf on the API: http://www.ghg.net/dharrison/OBDScanAPI.PDF

    Here's an alternate explanation of the API: http://www.obddiagnostics.com/obdinfo/info.html

    List of applicable standards (SAE books are expensive, but my library has 'em!):
    • J1978 - SAE-established standard for OBD II scan tools

      J1979 - SAE-established standard for diagnostic test modes

      J2012 - SAE-established standard accepted by EPA as the standard test report language for emission tests

    Trouble codes (OBD-II and non-OBD-II): http://www.troublecodes.net/technical/
    and http://www.obdiicsu.com/Docs/DTC/DTCData.html

    For those working at the hardware level: http://www.elmelectronics.com/thehome.html#ELM320

    Some more hardware fun: http://www.obd-codes.com/howto/index.php

    What other resources (standards, SDK's, libraries, tutorials, etc...) do you know about?

    J2534 - SAE established standard for "Pass through Reprogramming" of new vehicle ECUs through a generic hardware device. Flash programming files are available via each OEM, usually via their pay to use web site or via CD subscription.

      Scan Tool: http://www.scantool.net/obd_information.htm

      Looks to me like the same API as the others...From what I can tell, they all use the same API. Someone please correct me if I'm wrong and post the API.
