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
