Low-beams actuation, function (except code 614) - GF82.10-P-3002SK
MODEL 171.4 except CODE (614) Bi-xenon headlamp unit
Manual request
Function requirements:
- Circuit 30 ON
- Exterior lamp switch (S1) in position "low beam ON"
The actuation of the exterior lamp switch (S1) is read in by the driver-side SAM control unit with fuse and relay module (N10/1) via a discrete line. It actuates the following lamps via discrete wiring:
- Left low beam (E1e2)
- Left standing and parking lamp (E1e3)
- Right low beam (E2e2)
- Right standing and parking lamp (E2e3)
The driver-side SAM control unit with fuse and relay module (N10/1) transmits the message for switching the rear lamps on to the rear SAM control unit with fuse and relay module (N10/2) via the Controller Area Network Bus Class B (interior) (CAN-B).
The rear SAM control unit with fuse and relay module (N10/2) actuates the following lamps via discrete wiring:
- Left stop lamp, taillamp and parking lamp (E3e9)
- Right stop lamp, taillamp and parking lamp (E4e9)
- Left license plate lamp (E19/1)
- Right license plate lamp (E19/2)
Automatic driving light
Function requirements:
- Circuit 61 ON
- Exterior lamp switch (S1) in position "low beam AUTO"
- Message "night" from the rain/light sensor (B38/2)
The actuation of the exterior lamp switch (S1) is read in by the driver-side SAM control unit with fuse and relay module (N10/1) via a discrete line. To switch the illumination on, the driver-side SAM control unit with fuse and relay module (N10/1) additionally requires the "night" message. The "night" message is generated by the rain/ light sensor (B38/2).
It is read in by the overhead control panel control unit (N70) and transmitted via CAN-B. The driver-side SAM control unit with fuse and relay module (N10/1) actuates the following lamps via discrete wiring:
- Left low beam (E1e2)
- Left standing and parking lamp (E1e3)
- Right low beam (E2e2)
- Right standing and parking lamp (E2e3)
The driver-side SAM control unit with fuse and relay module (N10/1) transmits the message for switching the rear lamps on to the rear SAM control unit with fuse and relay module (N10/2) via CAN-B. It actuates the following lamps via discrete wiring:
- Left stop lamp, taillamp and parking lamp (E3e9)
- Right stop lamp, taillamp and parking lamp (E4e9)
Daytime running lamps
Function requirements:
- Circuit 61 ON
- The function is activated in the instrument cluster (A1)
The driver-side SAM control unit with fuse and relay module (N10/1) requires the "daytime running lamps active" message, which it receives from the instrument cluster (A1) via CAN-B. Additionally, the driver-side SAM control unit with fuse and relay module (N10/1) requires the "circuit 61 ON" message, which arrives from the EIS control unit (N73) via CAN-B. The driver-side SAM control unit with fuse and relay module (N10/1) actuates the following lamps via discrete wiring:
- Left low beam (E1e2)
- Left standing and parking lamp (E1e3)
- Right low beam (E2e2)
- Right standing and parking lamp (E2e3)
The driver-side SAM control unit with fuse and relay module (N10/1) transmits the message for switching the rear lamps on to the rear SAM control unit with fuse and relay module (N10/2) via CAN-B.
The rear SAM control unit with fuse and relay module (N10/2) actuates the following lamps via discrete wiring:
- Left stop lamp, taillamp and parking lamp (E3e9)
- Right stop lamp, taillamp and parking lamp (E4e9)
