Default 2011 Ranger Fault Code P1633

I received a check engine light. Diagnostic code P1633. The people doing the diagnostics said it is a TCM and itís a Ford dealer item only. Anyone have any insight on this?

I think this code means the pcm lost power to memory. I would check all the fuses first.
