Hello!
I also have the impression that my central differential is sometimes blocked without reason. As is well known, this can also be due to ABS sensors. But it could also be due to the signal path to the transmission control unit.
My thought is that in the control unit, which is also accessible via the diagnosis, there is a channel that reflects the blocking state.
That would be a pretty easy way to test it.
Just, does anyone know about the ECU's channels or even have a description?
Welcome
