I have been trying to figure out which pin of the CPU is being used as BDM pin connection. Looking at MC68HC916 pin doesnt seem to be the right processor for this. I'm checking the VDD and VSS connection, and it doesnt seem to match ( no connection when pin marked as VDD is tested using ohm meter ).
During my search about this ECU I've come about colby mentioning BDM port is available on this ECU (16 bit ECU) but I couldn't find any diagram/picture showing this.
Anyone have any information on this ECU's CPU pin out or BDM port ?
So far the closest datasheet I can find is MC68HC916 but the pin out from the diagram doesnt correlate, when I test the VDD pin (e.g. pin 40 and pin 120) or VSS (pin 41 and pin 121) the are not shorted together.
Any help will be appreciated.
