Description - MAIN BEAM HEADLAMPS - Alfa Romeo GT 3.2 V6

The vehicle has two main beam headlamps in the light cluster.The main beam headlamps are switched on by the steering column switch unit:when the dipped beam headlamps are on, by pressing the lever towards the dashboard (stable mode)in ''flash'' mode, by pulling the lever towards the steering wheel (unstable mode)The relay for switching on the dipped headlamps is managed by the Body Computer: the energizing of the relay is activated by the go ahead signals with the ignition key in the ON position (INT) and by the specific signal from the steering column switch unit.The activation and/or deactivation information is sent via the CAN: in this way the main beam warning light in the instrument panel is also switched on.The Body Computer also manages the ''dipped headlamps maintenence'' function: when the main beam headlamps are on, the Body Computer keeps the dipped headlamps on.

Functional description - MAIN BEAM HEADLAMPS - Alfa Romeo GT 3.2 V6

The Body ComputerM1is connected, via the CAN line, to the instrument panelE50to manage the main beam headlamps warning light.The main beam headlamps activation signal is sent to pin 33 of connector B of the Body ComputerM1from the steering column switch unitH5.The ''ignition ON'' signal (INT) for the switch H1 reaches the underdashboard control unitB2at pin 11 of connector H and from there moves on to the Body ComputerM1(pin 9 of connector F).The Body ComputerM1 controls the supply to the main beam headlamps by sending an earth signal to the engine compartment control unit B1B- from pin 9 of connector A of M1 - which energizes the relay T2: this supplies the dipped headlamps F10 (left) and F11 (right).The circuit is protected by fuse F2 of the junction unitB1A.
