    First go to ediabas.ini and make the following change

    Code:
    ;Interface      =STD:OBD
    Interface      =ADS
    And retry.


    If that doesn't work

    You only have TxD connected or RxD is shorted to TxD or TxD2 (OBD2) in the 16 to 20 pin adaptor. In the OBD2 16 pin to BMW 20 pin connector, measure where the following lines connect to on the 20 pin connector with a multimeter and post the results.

    OBD2.7 K line
    OBD2.8 K line
    OBD2.15 L line



    EDIT: Also are the following pins populated on your 20 pin vehicle socket?

    OBD.2
    OBD.17

    Thanks joylove, a step in the right direction! I changed the interface type to ADS and the ignition indicator is now lit which was encouraging but now I'm getting a different error, "SYS-0012 Identification Error".

    Didn't catch your edit before I went to the car last, will update ref: 20 pin socket. - Pins 2 & 17 are not populated.

    OK. Can you detail what you are testing when you get that error?

    So I guess the KOMBI and ZKE aren't responding.

    There is an issue with your RxD line. Your adaptor has two transceivers which is good. One will be connected to TxD and RxD need to be checked that is connected to the other transceiver.

    Inspect the end of the RS232-OBD2 plug on the adaptor. Are the following pins populated

    OBD2.7 K line
    OBD2.15 L line

    And the following pin not populated

    OBD2.8 K line

    Check with your multimeter that OBD2.7 K line connects to OBD.20 TxD. Check that it is not connected to OBD.15 RxD.


    Check with your multimeter that OBD2.15 L line connects to OBD.15 RxD. Check that it is not connected to OBD.20 TxD.

    you need a 20 pin round socket ADS interface not an OBD 20 pin round socket to access all the modules one thinks...



    see if pin 15 is populated in your socket under the bonnet..



    an ADS/OBD switchbox interface is another method of guarenteeing connection to pre OBD ADS modules and later crossover and OBD cars..

    Main screen once ignition is switched on


    Modules I'm attempting to access


    Error message



    I have tested the ODB2 to ODB pins as instructed and all tested OK. Any Ideas?

    I have a COM to EDIABAS OBD2 cable with an OBD2 to 20pin socket connected, I believe it uses an ADS interface. INPA interface in ediabas.ini is now set to ADS at least.

    Pin 15 is populated under the bonnet.

    15 maybe wired in your 20 round pin interface connector but its just a useless 20 to 16 pin OBD converter, as 15 is not wired in on the 16 pin OBD connector so it connects to nothing when jumpered together...it does not convert it to an ADS interface it just makes the round pin interface into an OBD interface, all your doing is connecting to your car via the 20 round ADS socket via a 16pin OBD interface and thats why you cannot access all the modules ...


    inpa set to ADS mode will only work with a serial interface not USB, but will connect to both old ADS (with the right interface) and OBD (with an OBD interface) aswell..

    your options are: a correct ADS interface which are expensive and rare these days, or the above switchbox interface which will switch and connect between both ADS and OBD systems..

    read the help list on the page it explains it pretty well..

    Thanks for the info, looks like i've wasted my money unless I can modify my cable for an ADS interface? If this is possible I'm reasonably handy with a soldering iron so I can give it a go, nothing to loose at least.

    On a plus note i'm not using a USB to COM cable as my laptop has multiple COM ports.

    15 may or may not be wired in your 20 pin round interface, i had 1 apart a while back and it was wired on that one, but as mentioned when jumpered to the 16pin obd it dosent actually go anywhere in the 16 pin obd cable as its not wired..
