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 headlight driver module is fitted as a printed circuit board in the LED headlight. The headlight driver module evaluates the signals sent from the footwell module (FRM) via the LIN bus and K-CAN3. In this process, the headlight driver module assumes control of the following lighting functions of the LED headlight:
- Side lights
- Daytime driving lights
- Side marker light
- Turn indicator
- Positioning light
Besides the lighting functions, the headlight driver module also controls the stepper motors for headlight beam throw adjustment and for the adaptive headlight.
