This gets me back to my original question. Does anyone actually have a copy of the 12-10-15 TSB that is supposed to address this specific problem? I'd like to see what the procedure is. Being a systems engineer myself has been helpful in the past when the service techs at the Ford dealership and I had to work together to try to figure an issue out. Dealing with all sorts of computerized equipment, from embedded systems up to online services with 100k+ servers, over the past couple of decades has taught me that there are very few issues that are completely new. Most are just slight variations of things that have happened before. :)
When it comes to new stuff like this, the techs at my local dealerships (and I suspect most every dealership) are often at a loss unless there's a very specific TSB from Ford about it or they've seen that exact issue before. While I can play around with it for hours figuring it out if I want, they are locked into doing work that they can charge labor to a customer or Ford for, so they don't have the freedom that I do. I can often do a slightly better job on even routine stuff because I can take my time and tweak/clean every little thing perfectly, where they know they have to get done in the time rated for the task in their systems.
