Description - HEADLAMP AGLINMENT CORRECTOR - Alfa Romeo GT 2.0 JTS

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 on the panel beside the steering wheel allow the headlamps to be orientated 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.The set value is memorised and displayed on the instrument panel.The control logic described above is managed directly by the instrument panel node.The device is enabled only when the dipped beam headlamps are on.The relay which controls the switching on of the dipped beam headlampsalso 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.

The dipped beam activation signal is sent to pin 4 of connector D of the Body ComputerM1from the stalk unitH5.The Body ComputerM1controls the supply to the dipped beam headlamps, sending an earth signal to the unit under the dashboardB2- from pin 8 of connector F ofM1- which energizes the relay T1; this supplies the dipped beam headlamps and gives enablement to the headlamp adjustment motorsF10(left) andF11(right).The headlamp adjustment control, located in the unitH10, sends a control signal - when the relevant buttons are pressed - to the instrument panelE50- pin 11 of connector B: the internal logic of E50 then sends (with dipped beam lights on) the supply to the motors from pin 5 of connector A, while pin 6 of connector A receives the reference signal.
