- Outside temperature sensor
- 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).

K-CAN SIGNALS CHART
![Exterior Rear View Mirrors](images/books/4361/index 27(14).png)
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
