6 Series 630i (N52K) Coupe
Brief description of components
The instrument cluster receives input signals from the following components:
-
Outside temperature sensor
The outside temperature sensor supplies the value for the temperature outside the car to the instrument cluster.
The outside temperature is shown on the liquid-crystal display. Instrument resolution is 0.5
°
C (1
°
F). The
value for outside temperature is also made available to other control units via the K-CAN.
-
Fuel-level sensors, left and right
The fuel tank contains two fuel-level sensors. Each fuel-level sensor sends a signal indicating the amount of fuel
in the tank. A value is obtained by adding the two signals.
> E70
The fuel level sensor is connected to the junction box electronics (JBE). The signal is transmitted to the
instrument cluster on the K-CAN.
-
Coolant-level switch
The coolant-level switch sends a signal if the coolant level is too low (Reed contact). The information is output
on the liquid-crystal display in the form of a Check-Control message.
> E70
The coolant level sensor is connected to the junction box electronics (JBE). The signal is transmitted to the
instrument cluster on the K-CAN.
-
Windscreen washer fluid level switch
The washer fluid level switch sends a signal when the washer fluid level is too low. The information is output on
the liquid-crystal display in the form of a Check-Control message.
> E70
The washer fluid level switch is connected to the junction box electronics (JBE). The signal is transmitted to the
instrument cluster on the K-CAN.
-
Parking brake warning switch
The parking brake warning switch indicates that the handbrake is applied. When the parking brake is applied,
the brake system warning lamp lights up red as a permanent indicator lamp.
> E70
The X5 does not have a parking brake (electromechanical parking brake = EMF). The parking brake button is
connected to the Dynamic Stability Control (DSC). The DSC transmits the signals on the PT-CAN to the junction
box electronics (JBE). The JBE transmits the signals on the K-CAN to the instrument cluster.
-
Axial buttons direction of travel full-beam headlight switch
> E6x
The axial buttons (check-control button at top, on-board computer button at bottom) are for the following
functions:
•
Menu of the Check-Control system in the liquid-crystal display and clock/date toggle
•
Menu of the on-board computer in the liquid-crystal display
The signal generated when one of the axial buttons is pressed is transmitted through the bus system.
> E70
The E70 has an on-board computer button and a rocker switch on the turn-signal/main-beam switch. The
signals from these two switches are transmitted by a direct wire to the instrument cluster.
-
Reset button in the instrument cluster
The reset button is used for the following functions:
SBT Instrument cluster E60, E61, E63, E64, E70
