    you only had the door open, but not turned on the car? If there are
    additional buses, they may be switched off until the car is turned
    on…<br>
    <br>
    The OBD connector scheme is the general pin assignment, I meant the
    specific VW e-Up schematics. But if you don't see any voltages with
    the car turned on, that's bad news.<br>
    <br>
    There may still be some command interface for the OBD gateway to
    enable live data, but without any info about the gateway, it will be
    hard to even find out how to address it.<br>

      <p>Hey guys,</p>
      <p>If I did nothing wrong I have bad news:</p>
      <p>@Michael:<br>
        With OBD port schematics I think you mean this

        Specifically if there are some other pins used than the standard
        CAN pins 6 and 14.<br>
        So I had the drivers door open, no key in ignition and measured
        the voltages of all pins in relation to pin 5 (signal ground).
        There is no voltage on any pin besides 2.5V on 6 and 14, and 12V
        on 16 of course. So there are no hidden CAN buses (or any other
        signals) afaict.</p>
      <p>@Mark:<br>
        Thanks for the hint with the can log. It's way easier than RE
        Tools for just checking if there is any traffic.<br>
        Having said that... there is no traffic whatsoever besides what
        I am polling and the reply. Even when ignition is on I only see
        the poll and the reply on the can log</p>
      <p>So it seems devmarxx was right: The gateway shields everything
        and there are even no other hidden signals on the OBD port.</p>
      <p>I'm happy to try any other ideas you guys have. Just let me
        know!</p>
