3/11/2020 UPDATE: Replaced the MTV pcb and it said to initiate FHU. Which is different than before, a minor positive step forward but then flipped to HAND A ,DOOR PWR OFF , hit Inspection down to land it slightly below bottom floor level...EMS MOVING NO PULSE. Cleared that err. ACT CLR .. NO ERRORS. Repeating in attempt to initiate FHU. ERR30 POPS UP. INIT FHU NVR BAD. Going in circles. That leaves me to believe possible motor encoder, something locked up with motor itself, worm gear... or the flux capacitor is out. Poke'n and hope'n. Real input appreciated.
