- Junction box electronics JB
- Outside mirror, passenger's side
- Mirror adjustment switch in driver's door switch cluster SBFA
- Outside mirror, driver's side
K-CAN2 - Body CAN 2
Instrument cluster (1) records the outside temperature and makes this information available to the vehicle electrical system.
Junction box electronics (4) supply the outside mirror heating. The outside mirrors (5 + 6) can be adjusted with the mirror adjustment switch in the driver's door switch cluster (6).

The instrument cluster (19) receives the value corresponding to the outside temperature from the outside temperature sensor (3) and makes it available via the PT-CAN. The footwell module (18) evaluates the KCAN2 signal and initiates activation of the outside mirror heating (5 and 17).
The mirror adjustment motors (9 and 13) are driven by the electronic mirror module. The electronic mirror module receives the request to adjust the outside mirrors via the LIN-bus. The outside mirrors are connected via the LIN-bus. All information such as the memory-position
or mirror functions, e.g. dip outside mirrors, is transferred via the LIN-bus. 8

Integrated Sensor System
The sensors that were previously accommodated separately in the DSC sensor
are now installed in the ICM
control unit.
The ICM control unit uses these sensors to calculate variables that provide key
information on the vehicle's
dynamic state:
