The messages are mostly self-explanatory. The gimbal appears to be disconnected and an accelerometer is broken or out of spec. It needs to be repaired.
@sabitante, FYI if you have Refresh or warranty from DJI that is an option. I chose to have @Thunderdrones repair my AC even though it was in warranty and I had Refresh. I knew I was looking at a charge and chose to support one of our people.
Here is a link where Thunderdrones (Rob) talks about what he does.
