On actuating an air conditioning function, the
MMI display switches back to its original menu
after a certain waiting time.
The information required for this is sent
from Climatronic control unit J255 to the
CAN-Convenience, converted into messages for
the MOST bus by Diagnosis interface for data
bus J533 and fowarded as optical signals to front
display and operating unit control unit J523.
This in turn converts the incoming signals into data
to be displayed on the respective display (J685)
which is connected.
