Switching on/off entrance/exit lamps, function - GF82.20-P-2022S

MODEL 220 

Interlinkage 

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

Function prerequisites: 

• Overhead control panel control module (N70) has recognized "night"  via the automatic light switch daylight sensor (B32/1).
• Door contact ON and OFF switch (N70s3) in position ON 
• Voltage not too low/too high

Only the entry/exit lamps in the open doors are actuated! 

Switch-on of entry/exit lamps: 

• An entry/exit lamp is switched on as soon as a corresponding door is opened.

Switch-off of entry/exit lamps: 

• The entry/exit lamp is switched off when the corresponding door is closed.

  If the door remains open for longer than 15 minutes the lamp is switched off automatically.

Switching back on following automatic switch-off 

The switch-on time is increased or started again when:

• A change in status occurs at any of the door contacts (S17/3, S17/4, S17/5 or S17/6)
• Circuit 15 is switched on
• The vehicle is locked or unlocked.

Actuation 

The entry/exit lamps are actuated by the associated door control module (N69/1, N69/2, N69/3 or N69/4).

The door control modules require the following CAN-messages for this purpose:

• Ambient brightness (night/day)  , this message is generated using the data from the automatic light switch daylight sensor (B32/1) in the overhead control panel control module (N70).
• The status of the door contact switches  (S17/3, S17/4, S17/5 or S17/6). All  door contact switches are read in by the rear SAM control module (N10/8).
• The locking and unlocking signal  and the circuit 15 status  are relayed on the CAN bus by the electronic ignition/ starter switch control module (N73).
  • If the automatic light switch daylight sensor (B32/1) is defective the lamps are actuated as if night  were recognized  .
  • The entry/exit lamps are independent of the setting on the automatic driving light circuit in the instrument cluster (A1)!
