GF82.20-P-2022R Switch Entry/exit Lamps On/off, Function

Component Identification:

An entry/exit lamp is located at the bottom edge of each door.

Function requirements:
^ 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

In general only entry/exit lamps of opened doors are actuated.

Switching entry/exit lamps on:
^ An entry/exit lamp is switched on as soon as the appropriate door is opened.

Switching entry/exit lamps off:
^ The entry/exit lamp is switched off if the appropriate door is closed.
The lamp is automatically switched off if the door remains open for more than 5 minutes.

Switching on again after automatic switch-off
The on period is extended or started once again if:
^ a change of status occurs at any door contact switch (S17/3, S17/4),
^ circuit 15 is switched on,
^ the vehicle is locked or unlocked.

Actuation
The entry/exit lamps are actuated by the relevant door control module (N69/1, N69/2).

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.
^ The entry/exit lamps are not dependent on the setting of the automatic headlamp control in the instrument cluster (A1)
