GF82.10-P-0003MCU Exterior Lights, Function
The exterior lights comprise the following functions:
^ Standing lights actuation
- Standing lights actuation
- Light warning
^ Driving lights actuation
- Low beams
- High beam and headlamp flasher
- Daytime running lights (with code (K06) Daytime running lights)
- Auto on/off driving lights(with code (V54) Rain/light sensor)
^ Turn signal light actuation
- Turn signaling
- Hazard warning flashing
- Hazard warning flashing when airbag deployed
^ Ambient illumination actuation(with code (V54) Rain/light sensor)
^ Stop lamp actuation
^ Front fog lamp actuation(with code (V07) Front fog lamps (FFO))
^ Backup lamp actuation
The SAM control unit (N10/10) is a subscriber in the Controller Area Network (data bus/CAN bus) (CAN) and the master control unit for the exterior lights and all flashing functions.
The following switches are read in directly by the SAM control unit:
^ Combination switch (S4)
^ Cockpit switch group (S6/1)
^ Stop lamp switch (S9/1)
The following sensor is read in by the SAM control unit via the Local interconnect network, interior 1 (LIN B):
^ Rain sensor / light sensor (B38)(with code (V54) Rain/light sensor)
The following information is read in and transmitted by the SAM control unit via CAN:
^ Crash signal from the restraint systems control unit (N2/7)
^ Feedback to the instrument cluster (A1)
The SAM control unit actuates the following components:
^ Left front lamp unit (E1)
^ Right front lamp unit (E2)
^ Left taillamp (E3)
^ Right taillamp (E4)
^ Center high-mounted stop lamp (E21)
^ Left additional turn signal lamp (E22/1)
^ Right additional turn signal lamp (E22/2)
^ Left license plate lamp (E19/1)
^ Right license plate lamp (E19/2)
^ Left front fog lamp (E5/1) (with code (V07) (Front fog lamps (FFO))
^ Right front fog lamp (E5/2) (with code (V07) (Front fog lamps (FFO))
Front fog lamp actuation
Function requirements
^ Standing lights or driving lights on
^ Circuit 15 On
Function
The request is made via the front fog lamps switch (S6/1s8) in the cockpit switch group and is read in by the SAM control unit, which actuates the front fog lamps.
The feedback is provided by the LED integrated in the front fog lamps switch.
Backup lamp actuation
Function requirement
^ Circuit 15 On
Function
The selector lever module control unit (N15/5) reads in the status of the integral backup light switch and actuates the left backup light (E3e3) and the right backup light (E4e3) when reverse gear is engaged.
