M-1-1-1 you view the status of the car and can enter car calls.
In that screen also look at the state the car is in is it NAV, NOR, ISC?
I doubt a selector magnet but stranger things have happened.
Is this a MOD or new install will make a difference for addressing I/O's?
You can look at the I/O's on the car link M-1-2-1 but you'll need the address of the COP board on the print to see the inputs for the calls.
Hopefully this helps and gets some more info to help TS.
LMK if you need any more help or docs?
