DIPPED HEADLIGHTS FUNCTIONAL DESCRIPTION

2.0 16V JTD, 2.2 16V JTD · MY 2005

The low beam activation command is supplied by steering wheel node control unit M093 via CAN line (pins 1 and 3 of connector A) to body computer node M001 (at pins 5 and 3 of connector G respectively).

Steering wheel node control unit M093 is connected to earth C015 (connector A) via pin 4 of connector A, and is supplied by two lines: one, from pin 11 of connector B of body computer node M001 to pin 5 of connector A; the other, from pin 1 of connector G of M001 to pin 4 of connector D, protected by fuse F04.

In turn, body computer node M001 informs engine junction unit B001 (pins 12 and 11 respectively of connector F) via the CAN line (pins 25 and 27 of connector E) that a low beam activation request has been made.

Engine compartment junction unit B001 suppplies pin 1 of left headlamp F010 and right headlamp F011 via pins 25 and 26 of connector G.

Warning light activation is controlled by odometer warning light node M140, which communicates via CAN line E1050 (pins 2 and 5) with instrument panel E050 (pins 6 and 12) and body computer node M001 (pins 8 and 10 connector D).

Body computer node M001 supplies odometer warning light node M140 at pin 4 and instrument panel E050 at pin 13 via pin 6 of connector D. This line is protected by fuse F14.

Dawn-dusk sensor K125 supplies information on the exterior light conditions to body computer node M001, at pins 3, 24, 26 (respectively) of connector L via pins 1, 2, 4.
