Main Beam Headlamps (Bi-Led)

DESCRIPTION: 

The vehicle is equipped with two main beam headlamps in the headlights.

The main beam headlamps are switched on from the steering column stalk:

• 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 main beam headlamps is managed by the Body Computer.

Activation and/or deactivation information is sent via the CAN: in this way, the "main beam" warning light is activated in the instrument panel.

On bi-LED versions, the bulbs are replaced with high brightness and high efficiency LEDs.

FUNCTIONAL DESCRIPTION: 

There is a single (ground) signal sent by the steering column stalk H005 to the Body Computer M001 that manages the main beam headlights in both fixed and flashing mode: from pin 2 of H005 to pin 36 of connector F of M001; the signal sent is coded by means of resistive dividers so that multiple information can be sent by the steering column stalk to the Body Computer via a single connection.

• The reference ground reaches pin 10 of H005 from pin 34 of connector F of M001.
• The Body Computer M001 - connector A - receives a direct power supply from the battery through the line protected by maxi fuse F01 of the engine compartment control unit B001.
• The Body Computer M001 receives an ignition-controlled power supply (INT) at pin 11 of connector E: this signal is used, amongst other things, to "wake up the network".
• The ground reference reaches pins 9, 10 of connector E of Body Computer M001.
• The Body Computer M001 controls the power supply for the main beam headlights in the headlamps F010 (left) and F011 (right) from pin 22 of connector B.
• The circuit is controlled by relay switch T02 and protected by fuse F09, both located in the engine compartment junction unit B001.
• The Body Computer M001 is connected through the CAN line to the instrument panel E050 to manage the "main beam headlights on" warning light.
