Unfortunately, lost communication codes happen all the time on Fords.
It doesn't necessarily mean anything is wrong with either module.
I bought an Autel bi-directional scanner and scanned our brand new 17 Escape, 2.0,
with 700 miles on it (and nothing wrong with it) had a couple lost comm codes.
I would make note of them and other codes, clear everything out and see what comes back up
just by turning on ign, then maybe move to what else comes up upon startup.
