BMW 7 Series: System Components

Interior Lighting, Front

The components for the interior lighting in the front roof area are integrated in the roof functions center and in the sun visors. The footwell lighting is located on the underside of the dashboard.

Interior Lighting in the Roof Function Center

The interior light unit on the F01/F02 is integrated in the roof function center. The interior light unit consists of:

• Reading light with button for driver and front passenger
• Interior light with button
• Ambient interior light for driver and front passenger.

The roof function center is matched to the color of the roof lining.

Various equipment options make it necessary to install additional components in the roof functions center.

If a panoramic glass roof is installed, the roof functions center contains not only the button for the panoramic glass but also the necessary control and monitoring facilities.

The ultrasonic interior movement detector is completely integrated in the roof function center on vehicles equipped with an anti-theft alarm system.

The rood function center simply loops through the signals for all other components. This means the components are connected directly to their respective control units.

These components are:

• Emergency call button
• Passenger airbag OFF lamp.

Interior Light Unit, Rear

The rear interior light unit incorporates the following lights:

• Reading light with button for left and right rear passengers
• Interior light with button
• Ambient interior light for driver and front passenger.

Interior Door Lighting

The interior door lighting comprises the interior door handle light, armrest light and door pocket light. The lights are in the form of LEDs with fiber-optic leads for light distribution. In addition, the doorway light is fitted in the bottom of the door. A 5 W bulb is used for the doorway light.

Map Pocket Lights

The map pocket lights are in the backrests of the front seats. An LED supplies light to a fiber-optic lead. The fiber-optic lead is integrated in the seat backrest. The light from the LED is directed downwards by the fiber-optic lead, thereby illuminating the map pocket.

Luggage Compartment Lighting

Two lights are used for the luggage compartment lighting. One of the lights is located on the underside of the rear parcel shelf. The other light is integrated in the tailgate. The light in the tailgate has two lenses. One of the lenses is colored red. When the tailgate is open, that lens serves as an indicator lamp for vehicles behind. The second lens directs the light downwards into the luggage compartment.

A 10 W bulb is used for each of the luggage compartment lights.

Control Units

The "interior lighting" function is distributed between several control units that communicate with each other via the K-CAN2. The individual control units are described in the following.

Car Access System

The Car Access System sends the request to unlock/lock the central locking via the KCAN2.

The signals are required to switch the interior lighting on and off.

Footwell Module

The footwell module detects the request to switch the interior lighting on/off based on the signals from the Car Access System, for example.

The footwell module provides a number of outputs for the interior lighting functions.

LIGHTING FUNCTIONS

The footwell module evaluates the status of the door contacts. The interior lighting is switched on when a door is opened. Each door switch is connected individually to the footwell module.

The footwell module analyzes the status of the front reading light buttons and front/rear interior light buttons.

Roof Function Center

The roof function center provides the power supply for the rear interior light unit. The front vanity mirrors also receive their power supply from the roof function center.
