Description - HEADLAMP AGLINMENT CORRECTOR - Fiat DOBLO 1.6 16v da 12/03
The vehicle is equipped with a device which makes it possible to directly adjust the headlamp beam, according to the load, from the driver''s seat. The headlamps are thus always aligned quickly and correctly.The adjustment device consists of a motor mounted on each of the two headlamps which tilts them as appropriate, lowering the light beam if the car is heavily laden, and raising it if the load decreases.A specific knob on the facia next to the dashboard is used to select the four possible positions.The position selected is shown in a display in the instrument panel.The device is only enabled when the dipped headlamps are switched on.The headlamp adjustment circuit is protected by the same fuses as the dipped beam headlamps circuit, located in the junction unit under the dashboard.
Functional description - HEADLAMP AGLINMENT CORRECTOR - Fiat DOBLO 1.6 16v da 12/03
The front headlamps are adjusted via a selector in the left section of the instrument panel E50 . According to the value chosen using the special selector, E50 sends a voltage regulated signal to the junction unit under the dashboard B02 via pin 5 connector A. From there the signal is then sent to pin 1 connector A of the headlamp alignment motors control unit (pin F for the left headlamps F10 and right F11 ).The motors N30 and N31 in the headlamps contain a transducer that establishes the travel according to the regulation signal voltage.The supply for the headlamp alignment system located in the headlamps (right front F10 and left front F11 ) goes from the relay R1 , housed in the junction unit under the dashboard B02 , via a line protected by fuse F13 for the left headlamp and fuse F12 for the right headlamp both housed in the junction unit.When the dipped headlamps are activated, the body computer energizes the relay R1 which sends the supply to both the headlamp alignment motors from pin 3 connector A of the junction unit B02 entering pin D of the left headlamp F10 and pin 12 connector A of the same junction unit entering pin D of the right headlamp F11.At the same time, a signal is sent to switch on the dipped headlamps from pin 14 connector G of the junction unit B02 to pin 6 connector A of the instrument panel E50 .
