Forgive me if I’m missing something here, but if the original driver for the TCMA solution was a mechanical problem, ie: possible fretting corrosion on a splined shaft, would not a simpler solution have been to address that alone, by either redesigning the spline coupling, and / or by testing, then limiting lifetime hours for that component, well within safe limits ?. Instead, it seems that we have a complex software solution, depending on several sensor pathways, that can only increase the possibility of failure, due to the increase in complexity ?.
