Ill try to get those tonightWould be good to see what the Can Networks look like on a scope at the Gateway !!

MOST DEFINITELY. Which is why I am leaning towards a bad J519 or a bad pinout of the ECU. Regarding the J519, that is why my only question was how can I hook that up and pull the codes (I bought a replacement just in case). But now I am leaning more towards the ECU being pinned wrong.If gateway works on the bench but not in the vehicle you either have a wiring problem or can bus problem possibly.
The only way we have found is to study the factory wiring diagram for the car that the ECU in question belongs in.There has to be a way to read inside the ECU and get the pinout internally from the ECU. Meaning, what does the ECU say T94/8 goes too (temp sensor, O2 sensor, J682, etc).....any way to get that?
A lot of waffle again - I've given you the factory diagram for the Gateway !! Now go get communication with it - Every other module does not count at this stage !!MOST DEFINITELY.

Unfortunately, regarding the ECU, Ive repinned it 3 times now. I have the FSM, the Work Shop manual and had alldata. With all 3 of these resources the pinout on the ECU (T94 and T60) all differ from each other.
And even though the workshop manual is VIN specific, its not entirely correct either.

Do you think I'm new?! I've done all that and then some!
Then behave as though you are not new to thisSo I will try what you mentioned , j533 connector, I'll depin all wires except the 5 you memtioned and let you know what happens. - SO YOU DONE NOTHING
Done nothing?!?!! Don't get me fucking started. Do you think because someone asks for help, that it gives you a free pass to be an asshole? I've done exactly what you suggested a couple of times before. I did it to humor you. Because I already knew what message I would get. You know what it was.....the same fucking message I've been saying.A lot of waffle again - I've given you the factory diagram for the Gateway !!

No you haven't done what I asked you to do - Your dreaming about ECM pins
Your strategy will NOT fix this car. You demonstrate poor understanding of how the car communicates with VCDS even poorer listening skills to good logical robust advice !!
I understand what you're saying. Let me give a specific example and I can attach pictures straight out of the fsm.....and it's wrong.I think we need to pump the brakes here. The factory wiring diagram is always correct. Sumdata or anything else I known to have incorrect information in it all the time for as long as I can remember. Factory diagram can be hard to read if your not familiar but gives a accurate break down of what is used in the vehicle or not. If you insist on using something other than the factory wiring diagram then It will be hard to anyone to assist as we can only follow what we know Is accurate information.
K. 1 secPlease check Pin1 on gateway module for power and pin11 for ground. If you dont have 12vdc on pin1 please check fuses sb 15 or sb24 depending on ebox version.
OK, key OFF J533 Pin 1 has battery voltage. Pin 11 is a good groundK. 1 sec
So the battery is dropping to 11.5V with the ignition on.HOWEVER, as soon as key "ON", all fuses drop to 11.5v
Is my ignition causing the voltage drop?
battery is still connected to a "maintainer". Yes, battery voltage is 12.5 (not sure why its low on a maintainer) and when "Key ON", battery drops to 11.5vPossible other consumers are coming online pulling battery voltage down a bit is the battery fully charged?
Ok since we don't have and auto scan posted. Is it possible to post one so we can what is and isn't online/talking.
