GF82.10-P-3002QQ Low-Beams Actuation, Function



GF82.10-P-3002QQ Low-Beams Actuation, Function
- with CODE (614) Bi-xenon headlamp unit



Component Identification:






Function requirements:
^ Circuit 15R ON
^ Rotary light switch (S1s1) in "Driving lamps ON" position

Function
The position of the rotary light switch (S1s1) in the light switch module (S1) is read in voltage-coded by the front SAM control unit with fuse and relay module (N10/1) via a discrete line. Via discrete line, the front SAM control unit with fuse and relay module (N10/1) actuates the following lamps:
^ Left low beam (E1e2)
^ Left standing and parking lamp (E1e3)
^ Right low beam (E2e2)
^ Right standing and parking lamp (E2e3)
^ Left front side-marker lamp (United States of America) (E6/1)
^ Right front side-marker lamp (United States of America) (E6/2)

At the same time as the front illumination is actuated, the front SAM control unit with fuse and relay module (N10/1) forwards the corresponding message via the Controller Area Network bus class B (interior) (CAN-B) to the rear SAM control unit with fuse and relay module (N10/2). Via a discrete line, the rear SAM control unit with fuse and relay module (N10/2) actuates the following lamps:
^ Taillamp and left parking lamp (E3e2)
^ Left front fog lamp and taillamp (E3e5)
^ Taillamp and right parking lamp (E4e2)
^ Right rear fog lamp and taillamp (E4e5)
^ Left rear side-marker lamp (United States of America) (E6/3)
^ Right rear right rear side-marker lamp (United States of America) (E6/4)

The xenon headlamp control unit (E2n1) in the right lamp unit acquires the signals from the front axle headlamp range adjustment sensor (A52) and the rear axle headlamp range adjustment sensor (A51) and from the ESP and BAS control unit (N47-5), and forwards these to the xenon headlamp control unit (E1n1) in the left lamp unit. The control units compare these signals with the current headlamp setting and, if necessary, actuate the left headlamp range adjustment motor (E1m1) and the right headlamp range adjustment motor (E2m1) in order to correct the low beam incline angle.

Speed-sensitive adjustment rate
The signal from the EPS and BAS control unit (N47-5) notifies the xenon headlamp control units of the current driving status.
If the vehicle is stationary or moving at a constant speed, the motors operate at a slow adjustment rate (static mode). If the vehicle is accelerating or braking, the adjustment rate is increased (dynamic mode).
