  • OBD response format

    Hi,

    I am writing some C# code to communicate with my OBDKey bluetooth device, and I am having some data issues on a few different vehicles, specifically a '99 VW Passat. Anyways, when I use a Chinese clone BT device, this is what I see:

    Request:
    0100

    Response:
    0101
    41 01 01 07 6D 00
    41 01 00 04 00 00

    The 2 responses is related to a multiple ECU issue (I think) that I posted about last Friday but hasn't shown up on the forum yet. However, with the OBDKey device, I see the following:

    Request:
    0101

    Response:
    0101
    41 01 00 04 00 00 13 48 6B 10 41 01 01 07 6D 00

    This data seems very interesting to me. Not only does it put all the data on a single line, it inserts some interesting stuff in the middle that looks like header information. Now, I was playing around a few days ago with some header settings on the device and what not, but I have cycled power to the device several times and sent many ATZ commands since then to restore to it's default state. I was hoping someone might have some insight into this issue or some things that I could maybe do to troubleshoot the problem.

    Thanks to everyone in advance!

    That is header information -- something is wrong with the settings if it doesn't separate those properly. Hopefully there's some sort of reset available to get you back to the defaults.

      That's also what I was hoping, however ATD, ATZ, etc. didn't help anything. Any ideas what setting could possibly result in this sort of behavior that wouldn't be reset to its default with an ATZ?

        Best option would be to contact their technical support. I just checked their website and noticed everything is email-based; no address, no phone number so cross your fingers. You have to wonder if that's a serious business without that kind of info posted. Yuck.

        There's also a possibility that you didn't screw-up any settings and that the tool just doesn't work very well.
