Schindler 3300 Getting 3556 fault under menu 50

Have reset with 101 1 & tried 127 1 on access & reset
button and 125 1 but I'm not sure about the jumpers on 5- & 9-10 no prints)

Elevator is at top floor (6th)
Door clutch will pick like it wants to run and then drop. It
does this several times before faulting out.

I believe the display shows the elevator thinks it's at 1st floor even though it is at the 6th (top floor)

I suspect the 3556 is a safety circuit fault as the car won't
run on any mode even with door lock bypass

If it's a safety circuit and it's lost, if I fix the safety circuit.
will it auto correct the floor position?

Any help is appreciated
