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 LED main headlight module is integrated in the LED headlight.
The LED main light module controls the following functions:
- Low-beam headlights
- High-beam headlight
- Headlight flasher
The lighting functions are controlled via terminals 56 a and 56 b.
The LED main light module also regulates the temperature control in the LED headlight. The values of 3 temperature sensors and the signals relating to driving speed and ambient temperature serve as an input signal. The temperature control also includes a function for de-icing the LED headlight.
The data from the LED main headlight module are sent to the footwell module (FRM) or the front electronics module (FEM) or to the body domain controller (BDC) for diagnosis of the fan and temperature sensors.
