^
The overhead control panel control module (N70) has detected "night" through the lights on sensor (B32/1).
^
Door contact ON and OFF switch (N70s3) in ON position
^
no undervoltage or overvoltage

The door control modules require the following CAN messages for this purpose:
^
The ambient intensity ; this message is generated (night/day) with the data of the lights on sensor (B32/1) in the overhead control panel (N70).
^
The status of the door contact switches All (S17/3, S17/4). door contact switches are read in by the rear SAM control module (N10/8).
^
The unlocking and locking signal and the status of circuit 15 are transmitted by the EIS control module N73) over the CAN.
^
a fault exists at the lights on sensor (B32/1) the lamps are operated as if night detected.
