    HI,

    Having now got my car on the road i want to fix a few niggling issues... to do this i want to be able to communicate diagnostically to several ECUs. (airbag and Engine ECU, BC)

    Currently i can communicate to the EWS and IHKA (aircon panel) but no other ECUs.

    As all ECUs are pretty much connected on the same bus is anyone aware of what could cause this issue?

    (i have a 1999 e36 cabriolet).

    Regards

    Karl

    I've just noticed that maybe this should be moved to another part of the forum.... ECUs how do i do this?

    i am using a USB Omitec obd diagnostic lead (16pin), a 16 to 20 pin converter and Ediabas Toolset. It worked correctly on my old MINI......The mini was like the E46 with the Kombi as the diagnostic gateway.

    I am guessing maybe there is a slight protocol difference between all of the ECUs and my diagnostic setup..

    I was just wondering if there would be an issue that could cause all of the other ECUs to stop responding... My original post was very vague, sorry.

    I have read about the ECU pins tin plating and potential comms issues, i dont think this is the case. The hood works correctly therefore it must be communicating ok with the GM5 to lower the windows.

    I am thinking about buying a carsoft unit, maybe it will help.
