Having an issue with floor security on Older 411. Software AAA30396AAD. Group of 2 cars.
During normal business hours the floor should be accessed by the General Public, after hours the timer drops voltage from E5 to RS board, changing i/o2532. This should secure the floor,unless a code is entered.

No matter the status of 2532, a code still has to be entered to access the floor.
Floor codes can be changed and cleared using the Secure/Clear Key switch procedure.
i/o 2532 is changing state when E5 is removed from RS Board. (the only way to make changes with the code is if 2532 is low)
One thing that is different on this setup and and not found in the T.I.P. documents/manuals anywhere is the car has to be Independent to make the changes to floor access codes.


Looking for any ideas.
