Diagnostic systems have a high rate of false positives, meaning maintenance crews spend a lot of time trying to repair components which aren't broken.
Not to put to fine of a point on this, but a false positive, is a broken component that isn't registering as bad. A false negative, is an indicator of a failure that isn't there.
