198000357 - E2012 MAIN BEAM HEADLIGHTS - DESCRIPTION

DESCRIPTION

The vehicle is equipped with two high beams in the headlamps.The main beams are switched on by the steering column switch unit:- with the dipped beams on, by pushing the lever towards the dashboard (stable mode)- in flashing mode, by pulling the lever toward the steering wheel (unstable mode)The switching on of the high beams is managed by the Body Computer.A special relay in the engine compartment junction unit controls the activation of the main beams via two lines protected by specific fuses. The high beam activation relay is controlled by the Body Computer: relay excitation is activated via a specific stalk unit control signal.Activation/deactivation information is sent via the CAN: in this way, the main beam warning light is activated in the instrument panel.

There are two main beam bulbs on versions with xenon headlamps: The first tradition (halogen) one comes on in "flashing" mode; when there is a switch from dipped to main beam headlamps, the xenon bulb remains on and a metal screen is moved, by means of a motor, being lowered for dipped headlamp operation and raised for main beam headlamp operation.    See descriptions 5540 EXTERIOR LIGHTING
