Would anybody please have wiring schema how is the ceiling infodisplay with seat belt reminders powered and connected to BSI for C5 X7 2012? I have GPS logger placed in the dashboard fuse box. Unfortunatelly it has relatively big case and when I want to close the fuse box I have to push the logger deep inside near the BSI. Since last time I did that the ceiling display is not working, I must have accidentally unplugged/snappped something.
What I have tried so far:
- According to datasheet the display is powered through fuse G32? This fuse is OK and I can sense +12V on both sides of the fuse.
- Took down the ceiling panel, disconnected the display and tried to sense volatge on the connector. I couldn't sense any voltage on all of the 3 pins but I don't know if it is beacuse the positive wire is disconnected somewhere or beacuse ECU disables power when no end device is found.
