2427908 - E2012 MAIN BEAM HEADLAMPS - Description

Description

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 headlampa maintenence' function: when the main beam headlamps are on, the Body Computer keeps the dipped headlamps on.  See E2011  DIPPED HEADLAMPS
