Light warning, function - GF82.10-P-2008C

MODEL 203 

Fig 1: Light Warning Manually Function Diagram

Light warning with parking or driving lights switched on manually, function 

Light reminder functional sequence for manually actuated standing or driving light 

Basic requirements:

• The electronic transmitter key (A8/1) is located in the electronic ignition switch control module (N73).
• The exterior lamp switch (S1s1) of the light switch module (S1) is set to "Standing lamp ON" or "Headlamps ON".
• The following signals are applied to the instrument cluster (A1) via the CAN interior: "circuit 15R ON", "standing lamp ON" and the "left front door is closed".

1. The electronic transmitter key (A8/1) is removed from the electronic ignition switch control module (N73).
2. The left front door is opened:

   The rear SAM control module with fuse and relay module (N10/2) detects by means of the signal of the left front door contact switch (S17/3) that the door is open and sends the signal "Door open" to the instrument cluster (A1).

3. The instrument cluster (A1) registers the altered signal situation and, because the signal "standing lamp ON" is still applied to the front SAM control module with fuse and relay module (N10/1), an acoustic visual warning is actuated with the warning buzzer (A1h1).

Light reminder function for automatically sensor controlled driving light 

Light reminder functional sequence for automatically sensor controlled driving light 

Basic requirements:

• The engine has stopped, terminal 61 is switched off.
• The electronic transmitter key (A8/1) in the electronic ignition switch control module (N73) is set to "circuit 15c".
• The exterior lamp switch (S1s1) of the light switch module (S1) is set to "Auto".
• The following signals are applied to the instrument cluster (A1) via the CAN interior: "circuit 15R ON", "standing lamp ON" and the "left front door is closed".

1. The left front door is opened:

   The rear SAM control module with fuse and relay module (N10/2) detects by means of the signal of the left front door contact switch (S17/3) that the door is open and sends the signal "Door open" to the instrument cluster (A1).

2. The instrument cluster (A1) registers the altered signal situation and, because the signals "standing lamp ON" and "circuit 15 ON" from the electronic ignition switch control module (N73) are still applied to the front SAM control module with fuse and relay module (N10/1), an acoustic visual warning is actuated with the warning buzzer (A1h1.
