If I remember rightly it gives you class three faults. I'll check later on when I get on one. Class three faults don't always mean something serious is wrong. Usually they are indication of maybe one chanel in a sensor down or something similar. They are worth monitoring on critical systems such as flight controls FADEC etc..., but in general only use them for fault diagnosis. Don't start looking into them all whatever you do or the craft will never fly again!!!!
