GF82.10-D-3002HA Low-Beams Actuation, Function

- with CODE (LG1) Bi-xenon headlamps with cornering illumination

Low beam function
The low beam is actuated when the rotary light switch (S1) is turned to the "low beam" position.

In vehicles with code (JA5) Light/rain sensor, the low beam is also actuated by the auto on/off headlamps (rotary light switch in "AUTO" position).

If, with the low beam actuated and the transmitter key (A8/1) removed, the driver door is opened, the warning buzzer (A1h1) sounds. The warning buzzer is integrated into the instrument cluster (A1).

Networking of components
The components of the low beam function are networked as follows:
- The rotary light switch is read in directly by the SAM control unit (N10).
- The headlamp flasher/high beam switch (S144s2) of the combination switch (S144) is read in directly by the MRM control unit (N80).
- The MRM control unit places the signals on the Controller Area Network bus class C (engine compartment) (CAN-C).
- The EIS [EZS] control unit (N73) reads in these signals and places them on the Controller Area Network bus class B (interior) (CAN-B), where they are read in by the SAM control unit.
- The SAM control unit reads in the signals from the rain/light sensor (B38/2), with code (JA5) Light/rain sensor, via CAN-B.

The following lamps are actuated for low beam directly by the SAM control unit:
- Low beam (E1/6e2) of left XENON lamp unit (E1/6) via xenon control unit (E1/6n1)
- Low beam (E2/6e2) of right XENON lamp unit (E2/6) via xenon control unit (E2/6n1)
- Standing light (E1/6e3) of left XENON lamp unit
- Standing light (E2/6e3) of right XENON lamp unit
- Taillight (E3e2) of left taillamp (E3) with model 906.611/613/631/633/635/637/653/655/657/711/713/731/ 733/735 or taillight (E3/6e2) of left taillamp (E3/6) with model 906.111/113/131/133/135/153/155/211/ 213/231/233/235/253/255
- Taillight (E4e2) of right taillamp (E4) with model 906.611/613/631/633/635/637/653/655/657/711/713/731/ 733/735 or taillight (E4/6e2) of right taillamp (E4/6) with model 906.111/113/131/133/135/153/155/ 211/213/231/233/235/253/255
- Left license plate lamp (E19/1)
- Right license plate lamp (E19/2)

At the same time, in vehicles with code (E43) Trailer hitch socket, the signals for actuating the above-listed lamps are forwarded over CAN-B to the trailer connection unit [AAG] control unit (N28/1).
