2399291 - E3080 HEADLAMP AGLINMENT CORRECTOR - Description

Description

The headlamp beam orientation in accordance with the load is adjusted via the adjustment device located directly in the headlamps; it tilts them as appropriate in order to lower the light beam if the vehicle is particularly laden, and raises it when the load decreases.

Two buttons, located in the control panel to the left of the steering wheel, allow the headlamps to assume 4 vertical positions from 0 to 3:

• position 0: one or two persons on the front seats, full fuel tank, car fully equipped and in running order;
• position 1: five persons;
• position 2: five persons with luggage compartment full (about 50 kg);
• position 3: driver and 300 kg load, all stowed in boot (full load).

These 4 positions are produced using the '+' (the light beam is raised) and '-' buttons (the light beam is lowered).The set value is memorised and displayed on the instrument panel; when the dipped headlamps are switched off, the movement is disabled and the current position for the headlamp parabolas is maintained; when the dipped headlamps are switched on again, the display shows the headlamp alignment symbol with the number of the position memorized.This control logic described above is managed directly by the instrument panel node.The device is enabled only when the dipped beam headlamps are on.If there is a fault, the system positions the headlamps to prevent the drivers of vehicles coming from the opposite direction from being dazzled. The relay which controls the switching on of the dipped beam headlamps  See E2011  DIPPED HEADLAMPS also supplies the adjustment motors built into the headlamps; this relay for switching on the dipped beam headlamps is managed by the Body Computer: the relay is energized by enablement signals of ignition on (INT) and the stalk unit dipped beam control.
