It took my dealer a couple days to figure it out and once he added the brake controler code to my vin# and down loaded it to my truck it cure the dead battery and now the EVIC recognizes it also. I'll bet if the dealer would try it, it would solve your problem. These vehicles are only programed with the options included with the truck. The computer is smart enough to know something is hooked up, but can't recognize what it is if its not in the software and will continue to search for it.
The dealer did charge me like $85 to upload the brake controller code but I thought it was worth it.
