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 .Both the instrument panel E50 and the body computer M01 receive supplies controlled by the ignition (INT) and direct: at pins 11 of connector E and pin A of connector C of the junction unit under the dashboard B02 , respectively. There is a protective fuse F1 for the direct supply located in the engine compartment junction unit B01 .Pins 8 and 9 connector D of the body computer are connected to earth.
