BMW 7 Series: System Overview
The system circuit diagram for the outside temperature is displayed below.
The diagram is structured in such a way that only the control units and control
elements directly involved in the
instrument cluster are shown.
The instrument cluster receives a large number of different bus signals that
provide information (speed, CC
messages, etc.) for the various displays and indicators. These bus signals are
requests to the instrument cluster
and are therefore not listed in this product information.
The only directly connected component that can be seen in the system circuit
diagram is the outdoor
temperature sensor.
This input signal is read directly in the instrument cluster and made available
from here to all other bus users.
The outdoor temperature sensor wiring "passes through" the junction box and is
processed directly by the
instrument cluster.

Lumbar-support Adjustment
Using the lumbar support, the backrest can be individually adapted to the
spinal column and thus ensures
relaxed driving.
The button for the lumbar support adjustment is located on the side of the
center armrest and is connected via
the LIN bus to the seat module.
