GF82.10-P-2009SK Headlamp Actuation, Function

Driving light actuation consists of the following manual and automatic functions:

^ Manual driving lamp actuation via the exterior lamp switch (S1), position "low beam ON"
^ Automatic driving lamp actuation via the exterior lamp switch (S1) (position "AUTO") and the rain/light sensor (B38/2) (night-time detected)
^ Daytime running lamps depending on instrument cluster (A1) setting

Manual light activation

Function requirements:
^ Exterior lamp switch (S1) in low beam "ON" position
^ Circuit 30 ON
^ No overvoltage or undervoltage

Automatic driving light

Function requirements:
^ Exterior lamp switch (S1) in "AUTO" position
^ Circuit 61 ON
^ Rain/light sensor (B38/2) (night-time detected)
^ No overvoltage or undervoltage

Daytime running lamps

Function requirements:
^ Function has been set to active on instrument cluster (A1)
^ Circuit 61 ON
^ No overvoltage or undervoltage

The operation of the exterior lamp switch (S1) is read in via a discrete line by the driver-side SAM control unit with fuse and relay module (N10/1). It discretely controls the relevant front lamps. The relevant rear lamps are discretely actuated via the Controller Area Network Bus class B (interior) (CAN-B) by the rear SAM control unit with fuse and relay module (N10/2).
