It would depend on if the CPU has been flashed. If not, the BCM has a setting for DRL. If they have flashed the computer to update to 2014, the BCM doesn't have the capability.
But Ford has also been lying to it's dealers, claiming it is illegal to turn them on. It is illegal to hack the BCM, but if the capability exists in the BCM control software to turn on, it isn't illegal for a dealer to use a software program that the manufacturer provided to enable the feature.
Legally, I'm not sure why it would be considered hacking to enable a feature on your module, well, I guess for a purchased Energi. I don't remember signing any license agreement with Ford regarding the use of their BCM programming, specifically stating that modifications are not allowed. It may void your warranty, but I would think this would be considered "aftermarket" for legal purposes. If Ford were to consider legal action against you, it would be a waste of time for Ford to come after you for "hacking DRL function." You are attempting to improve the safety of your vehicle. Most of the "hacking" regarded to as illegal is for copying proprietary functions.
Anyways, I have a similar issue with a 2012 Toyota Prius v. It does not have DRLs. Modifying the fuse box with a DRL relay and relay block is the "factory" solution, but I never got brave enough to disassemble the car enough to remove/open the fuse box. Definitely would kiss my warranty goodbye. Since I have been researching for that, here's a possible solution:
It is currently being sold if you search under OSRAM LEDriving FOG DRL. It uses LEDs for decreased energy use, provides added cornering light functionality as well as retaining fog light function and adding the desired DRL function. I only wish the fog light portion was yellow, as I have some night blindness and personally believe yellow fog lights work best for fog.
