DESCRIPTION - HEADLAMP AGLINMENT CORRECTOR - Alfa Romeo 159 1.9 JTD 8V Fino a 12/05
The adjustment of the headlamp light beam according to the load is carried out by means of a special device (located inside the front light cluster) which tilts it appropriately, lowering the light beam if the vehicle is heavily laden and raising it if the load lessens.A special wheel, located in the controls to the left of the steering wheel, allows the adjustment of the headlamps in 4 vertical positions from 0 to 3:- position 0: one or two persons in the front seats, full fuel tank, fully equipped (vehicle in running order);- position 1: five persons;- position 2: five persons with full luggage compartment (about 50 kg);- position 3: driver and 300 kg load, all stowed in the luggage compartment (full load);The device is enabled only with the dipped beams on.The relay which controls the engagement of the dipped headlamps also supplies the adjustment motors inside the headlamps; this relay for switching the dipped headlamps on is managed by the Body Computer: the relay energizing is activated by TEG inserted (INT) enablement signals and by the steering column switch unit dipped headlamps control.
FUNCTIONAL DESCRIPTION - HEADLAMP AGLINMENT CORRECTOR - Alfa Romeo 159 1.9 JTD 8V Fino a 12/05
The dipped headlamps activation (earth) signal - and any AUTO function - is sent to pin 2 of connector I and to pin 28 of connector G of the Body Computer M1 from the steering column switch unit H5The Body Computer M1 controls the supply for the dipped headlamps sending an earth signal to relay T1 in the junction unit under the dashboard B2 from pin 8 of connector F of M1 which energizes relay T1: the latter supplies the dipped headlamps - pin 2 for the lamps F10 (left) and F11 (right); at the same time it provides the enablement for the adjustment motors - pin 6 for lamps F10 (left) and F11 (right);Each circuit is protected by a fuse in the junction unit B2 : F13 for the left headlamp and F12 for the right.The control for the headlamp adjustment, located in the unit to the left of the steering wheel H90, also receives the enablement supply - pin 5 of connector A, whilst a control signal produced by the adjustment potentiometer - pin 15 of connector B is sent; this control signal "passes through" the junction unit under the dashboard B and activates the adjustment motors built into the headlamps - pin 7 for the (left) lamps F10 and F11 (right).
