ADAHRS cross check errors?

[ds3fch]

Hi, Good Day.
May I have some explanation about the error messages? (SV-D1000)
-ASAHRS Cross check errors
-ZAON offline(ADS-B) (It is turned-on)
-AP disconnect broken
-Transponder fail (it is operating -communication error?)

Was the whole aircraft powered up? I have dual screens and get a ton of message if I only boot one. Since it says "other display offline" I assume it wasn't powered. Like the cause of all the messages.

Yes. Both SV-D1000 are working.

Looks like the two displays aren’t talking to each other then. If you go into setup and network status it should show the other display offline (in red) even though it’s on.

Perhaps doing a detect network devices will bring it all back.

have you done any work on it recently? Wiring harness could be loose or removed?

I had similar happen but two different causes.
1. Rainbow screen of death on right screen causes transponder offline error (and it doesn't work)
2. Loose network cable from screen one to radio head, causing right screen to see only the radio head (daisy chained via the radio from screen to screen).

If each screen detects different devices, it is likely a network connectivity related issue.

Check the aircraft battery voltage is ok. I had a problem when I first powered up with these sort of errors. Your backup battery voltage is low so I suspect all power is coming from aircraft battery

Hello,
I had this problem
it was about a cable of the belts which was magnetic and which created a difference between the two adahrs
to check

It is on the list of the network. (#5 and 6)

Mine was doing that . I was updating one d1000 with a complete update instead of obstructions only. Dynon said if I did that I would need to do it on both units. Moral of the story don't do the full update unless it needs it.

Interesting. DId you just update to V16? Have to do the displays separately. Unlike database update it won't crossfill.

That's just a guess. Have you figured anything else out?

Re the ADAHRS cross check errors. I was getting that message on my displays consistently, although mine were 'PITCH' and 'TURN RATE'. No way that I could trouble shoot it, so had to have one of my two units replaced. The factory was able to determine which one, and provided a replacement. Now works fine.

I also have this problem with the two ADAHRS and the message comes on constantly despite having disabled one of them on the screen. Would appreciate some help too...
