Forget about this DTC. It is caused due to the fact that the new HVAC module (digital) is a different module number. When your truck validates all the modules this one does not register correctly and gives the DTC code for not programmed. Your dealer would have to send a ticket to ford asking them to change the original part assigned to your truck to this module. They do this when a particular part is no longer available. Since the original HVAC control part that came with your truck is still available, there is a good/big chance, Ford will decline to make this change to your VIN and As Built. If yours is like mine and functions 100% correctly, I would not worry about this DTC at all. NOTE, I also have FDRS, and tried to program the module while linked directly to Ford system and it will not program/update without what I mentioned above.
