Well usually when this kind of thing pops up I state manufacturers software diagnostics is more likely not to get confused.
So in this case Ford diagnostics needed.
I have seen this kind of msg on some very high end diagnostic equipment.
So it's either main dealer or someone who has Ford IDS.
Or if you have a local "Bosch" diagnostic specialist they usually aren't stumped by weird MSG's.
