Communication problem with the Mokka 2016 instrument panel

Hello everyone I have an Opel Mokka from 2016 which the instrument panel does not work and gives airbag failures, TPMS, immobilizer etc, none of the needles work, in airbag I have the DTC U0155 also in BCM and in air conditioning, I have looked for a second hand and cloned BCM but the problem continues, I have passed a direct cable from the frame to the LIN communication radio but it is still the same, can anyone help me?

Any signs of water ingress & did you put lin wire from radio to cluster?

I put wire from pin3 cluster to radio,cluster have other wire communicattion in pin 12,what is lín ? Pin 3 cluster (grey-green) or pin 12 (white-green)

From what I can work out pin 3 IPC is LIN and should go to PCM (green)
Does the screen light up when door is opened?
I had similar issues on 2016 astra, I suspected driver door module but customer was happy with direct line from IPC to radio. From what I can remember the radio lin wire was wh/gn or gn/wh

The panel does not turn on when I open the door and the radio does not turn off when I close the car, there is also no communication with the diagnosis on the radio

Do you have access to wiring diagrams?

This is what I got but it seems not to be enough, the radio only gets a green/gray cable, I have taken a direct cable to the instrument panel but it still does not work, does anyone have any idea? I've tried another instrument panel but we're the same

---

in haynes the wire green-gray is connected to E64 PIN b16 (E64 is diagnostic control unit) Does anyone know what control unit this is?

THIS IS LOCATION OF THE UNIT CAN IT'S UNDER THE GLOVE COMPARTMENT THE INSTRUMENT PANEL CABLE HAS GOOD CONTINUITY WITH PIN 16 OF CONNECTOR B

E64 is injection module

Have you got diagrams for other modules?

You can find Lin bus (single wire) on another module and link to instrument pin 3, maybe climate panel
