    Question AutoTap ODB-2 cable...

    Instead of buying a new ODB-2 cable, can I simply reuse my autotap cable for custom communication with my car?

    Or did autotap intentionally cripple it somehow?

    I have an autotap unit for my car. Can I re-use that cable that came with my AutoTap?
    I'm trying to write my own custom program to read ODB-2, but I don't want to have to buy a cable if I can simply re-use the AutoTap's cable.

    download another OBD app and try it out, if it works chances are the cable is "not proprietary"

    great idea ... that would be the quickest way to verify that it'll work for my needs.

    Well, it didn't seem to work...
    I tried using this application:
    http://www.obddiagnostics.com/ProgWin.html

    I used a debug tool to sniff the traffic...

    TX: 20
    RX: 01 02 FF 05 00 07

    what does this mean? what response was the code looking for?

    Feel free to share your findings. I'm sure there are other autotap owners that might be interested. Myself included
