Fault with audio/radio system

When making a scan I have the following fault:

I have already checked the converters around the rear window but found nothing of note. I also checked the connection between the window on the small connector and that seems fine. So I doubt a little this has something to do with those converters. Does this fault point to another converter somewhere else?

Nobody?

Sounds like the wiring to antenna has a short

Beyond my knowledge but others might want to know if all the radio functions are working. Also, has the AM/FM/satellite reception changed in any way?

I checked the wire on the rear door to the glass with a multimeter and it has zero resistance indicating it is ok. I also replace the amplifier but to no avail. That's why I think this fault is pointing to something else.
