Phoinix - suggest you put VEMDs into maintenance mode and scroll around for the failure code. We get it regularly and, like MightyGem, give it a good ignoring.
When we first got the aircraft, we looked into every similar issue until we realised that they were invariably code 103 or similar, all occurring at 00:00secs - i.e. probably some small electrical hiccup with no likelyhood of it having occurred in flight or anything to do with handling errors.
Unfortunately, our experience has led us to follow the ignoring procedure above and ECD/TM (don't know whether it happens with P&W) have not addressed what appears to be a CAD/VEMD/FADEC electrical sensitivity issue to remove these "cry wolf" CAD warnings - one day it might be important/relevant, but we're unlikely to find it until the engineers download FADEC data. Only time we check it out is when we feel we might have mis-handled, which is hardly ever, of course!!
