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-CAN2 signals at footwell module


Exterior Rear View Mirrors

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



    Overview The following outside mirror functions are possible depending on the vehicle equipment: Mirror adjustment in up/down and left/right directions Mirror heating Mirror fold-in Electrochrom

     System Components

    Overview The following components are installed in the F01/F02 for the purpose of operating the outside mirrors: Driver's door switch cluster with Outside mirror adjustment switch Outside mirro



     IBOC System/HD Radio

    The IBOC (In-Band- On-Channel) system is offered as the digital radio. With the introduction of the CIC, the control unit of the IBOC system has been integrated in the head unit as the IBOC decoder. The IBOC system enables the reception of HD (High Definition) radio through the FM/AM double tune

     Initializing Telestart Handheld Transmitter

    NOTE: The Telestart hand-held transmitter must be initialized when: Hand-held transmitter is replaced Car Access System control unit is replaced The auxiliary heating is switched on under an ambient temperature of approx. 15ºC with the hand-held transmitter and at a preselected switch-on time.
