Peugeot 807 2.2 HDi 2004: Starter Spins, No Ignition, BSI Errors, Immobilizer & Transponder Issues

Hello
I have a problem with my Peugeot 807 2.2 HDi 2004 the car stopped firing, the starter spins and does not fire, when connected to a BSI computer, it showed problems with the connection with the climate, engine calculator, door module. The immobilizer has stopped reading the transponder from the key, in addition BSI shows the error "excitation in emergency mode". I replaced the BSI together with the engine controller and a new key but without changes it is the same. PP2000 can not connect to the switch module under the steering wheel where the transponder antennas are connected, I also replaced them but it also did nothing. of course, fuses checked, bundles initially too. I don't know what to do anymore, thank you in advance for your answer.

COM has power at all?
Pass the wires from communication between BSI and COM and the first thing to check is whether COM is receiving power.
Without this communication it will not and will not fire.

the power supply is on two wires in the first cube and on one wire in the second cube. it's hard for me to check passages in cables without a schematic and I can't find it anywhere. I have one more question if someone knows where the central locking module might be located, because this of course also ceased to operate ... supposedly there is an additional "control box" central outside BSI itself

The central lock is controlled by BSI.

Or:
4 is mass,
5 plus with BSI
6 plus with BSI but only for the older version
