System Overview: Control
| 1. | Central electronic module (CEM) | 4. | Motor, headlamp range adjustment |
| 2. | Rear electronic module (REM) | 5. | Suspension module (SUM) (vehicles with Four-C (Continuously Controlled Chassis Concept) only) |
| 3. | Position sensor |
An electric motor is controlled by the central electronic module (CEM) via a relay (ordinary high beam relay).
The motor drives a gear wheel which moves the reflector along its guides.
A sensor which detects the position of the reflector is connected to the motor.
- The electronics in the motor interprets the sensor information and generates a signal
- The signal is reconnected to the central electronic module (CEM).
If the reflectors are in the wrong position during high beam the reflectors are forced into a safety position;
- the warning lamp (orange) lights in the driver information module (DIM)
- an error message is also shown in the display in the driver information module (DIM).
If the high beam is activated with the light switch in 0 position, the high beam is only activated as long as the high beam lever is activated for a high beam flash. The headlamp switch must be in the "on" position in order for the high beam lamps to remain active.
