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.
