Left headlight driver module (STML) and right headlight driver module (STMR): Notes

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.
