I'm starting to think your TIU may have experienced some signal loss for the DCS signal, did you try a different TIU channel? If this is a Rev. L TIU, there is a recurring issue with the 74ACT244 chip losing gates and causing low DCS signal output. What happens is marginal locomotives start failing to add first, as more gates in the chip fail, more locomotives fail to be recognized. This has been discussed at some length here.
