Roof function center (FZD)
WARNING: This page does not describe the selected car, but rather 45 other vehicles, including the 2016 BMW M5, 2016 BMW 550i xDrive, 2016 BMW 550i, 2016 BMW 535i xDrive, and 2016 BMW 535i. However, it is still accessible from the selected car via links, so may be relevant.
The roof function center (FZD) with its integrated ultrasonic interior movement detector provides the signal for the optical alarm via K CAN2. The footwell module (FRM) can then allow the anti-theft alarm system to provide a optical alarm using the turn indicators.
The roof function center (FZD) supplies the rain-light-solar-condensation sensor with voltage.
The following graphic shows the high version using the F13 as an example.
