Function sequence for low beam actuation
Basic conditions:
- Combination switch (S4) set to "Low beam ON" position.
- The electronic ignition switch control module (N73) is programmed to "Xenon headlamp NO" and reports this and the position of the combination switch (S4) over the CAN interior to the front SAM control module with fuse and relay module (N10/1).

1 The exterior lamp switch (S1s1) of the light switch module (S1) is set to the "headlamps ON" position.
2 The front SAM control module with fuse and relay module (N10/1) registers the applied position of the exterior lamp switch (S1).
3 The front SAM control module with fuse and relay module (N10/1) actuates the low beam (E1e2 and E2e2) and the standing lamp and parking lamp (E1e3 and E2e3) and simultaneously sends over the CAN interior the "standing lamp ON" signal to the rear SAM control module with fuse and relay module (N10/2).
4 The rear SAM control module with fuse and relay module (N10/2) actuates the taillamp and parking lamp (E1e3 and E2e3) and the left license plate lamp (E19/1) and right license plate lamp (E19/2).

In the "Driving light ON" position the low beam and standing lamps are always driven together.
