Delphi DCM6.2V on Bench connection

Guys,
Need some help with bench connection for this ECU.
In car I always have the code P056200 System Voltage Low and engine cranks but does not start...

So I thought let me connect it on the bench with known good power supply and check if the code is still permanent.

I connected:
T94/1: GND
T94/5: +12V
T94/65: +12V
T94/87: +12V
T94/92: +12V

T94/67: CAN-L
T94/68: CAN-H

Reading trouble codes with Autocom still shows this error (beside all the other missing sensors off course) as permanent and I can not erase it.
Did I miss any connection (could not find a list with description of all pins) for GND or 12V to get rid of this P056200 error or is the ECU fried?

Your help is appreciated...

this error can only be effectively deleted after starting the engine and the correct battery charging voltage is present. in ecu dcm6.2v it is a normal symptom. this has no effect on starting the engine

Can someone please find me the right full Engine ECU wiring Diagram?
I did find one but it is not 100% matching.

For example T94a/92 is connected to switched terminal 30 via J317 in my wiring diagram.
In real it is connected to relay R2 in the front fuse box.
