Expert101 Cab-car Storung Light Issue

I noticed that the storung (fault) light on the right side of GSM-R keeps flashing and becomes constantly on after you press it, but it seems to start flashing again after a period of time. I don't seem to have any problems while driving, so I want to know what this means.
By the way, I also noticed that the hohe abbremsung light under the power meter is on. Is there a relationship between the two? My BP value is currently 5 bar.

 

Look up, there is a fault panel there that tells you where to look. Page 94 on the guide will help you further.
