Took some time yesterday morning to look at it some more.

The magnet was in place on the shifter.

Both coils on the park brake block had good continuity.

So, possibilities, the encoder board/armrest board has failed, pressure sensor on the park brake block, or the controller itself????? Again, no codes except the PCU 24. Is it possible to clear the code without being hooked to computer??? Just looking in the book, I should have several more if the controller itself has failed, or at least I think. Hydraulics/throttle all function properly. Sort of leaning towards the encoder board.
