rjahl, yes each of the three unmodified D-CAN cables allow for INPA to communicate with the vehicle, including exercising the DISA valves, and resetting errors. None of them were able to reprogram the DME, which was obviously reprogrammable using other tools. We have never needed to bridge pin 7 and 8 to get the diagnostic part to work. I honestly don't have any idea how the underlying communication with the DME is occurring (perhaps though the JBE?).
All this being said, we do not plan to attempt to reprogram the transmission via his ODB2.
I would really like to know if this in fact was our problem since there are likely more cars out there with the 6-wire ODB2 connector.
