Garmin G5 error message

[Jim K]

Been getting this in flight, but not on the ground of course. Started rarely, but now it occurs on every flight. Google search indicates it's probably a loose wire somewhere...any ideas where to start looking? Everything is working perfectly normally. Is there some sort of diagnostic or logging I can do to help diagnose it?

Check the LRU page in the settings. I bet the GAD29B is offline.

It sounds like the GAD29 is losing it's connection from the CAN Bus or possibly losing power or ground. It could be going bad, but I haven't seen that happen before.

 

[Gary Ward]

Never a good sign when something like that shows up on your G5. It usually means get your wallet out...

Does it ever happen during a runup? One possibility is a loose wire or bad solder connection in the wiring harness or a connector that manifests when it is vibrating.
