DIPPED HEADLIGHTS - FUNCTIONAL DESCRIPTION

1.3 JTD 16v · SUV

Operational description

The command for switching on the dipped headlamps is sent from the steering column switch unit H005 by turning the levers A and B (both switches have the same synchronous movement) to position 2.

The body computer node M001:

• receveis the negative signal (reference to earth C020) at pin 2 (side lights) and at pin 7 (dipped headlamps) connector P.

Earth C020 is secured to the passenger compartment floor and is positioned near the right front wheel arch (footwell area).

Having received the signal, the side lights (see wiring diagram E2010) and the dipped headlamps are switched on:

• from pins 7 and 8 connector B the dipped headlamps housed in the front light clusters F010 and F011 are supplied;

The two lines are protected by fuses F13 (left branch) and F12 (right branch) housed inside the actual body computer node.

The supply lines protected by fuses F12, F13 are operated by a relay integrated in the body computer node.

The command for activating the follow me home function is sent from the steering column switch unit H005 via button D (flasher).

The body computer node M001:

• receives the negative signal (with reference to earth C020 connector B) at pin 5 connector P
• See E2012 MAIN BEAM HEADLAMPS

Having received the signal, the dipped headlamps are switched on:

• from pins 7 and 8 connector B the dipped headlamps housed in the front light clusters F010 and F011 are supplied;

Pressing the levers D (flasher) for more than two seconds deactivates the function.

The body computer communicates, from pins 35, 36 connector I, via the CAN, with the instrument panel E050 (for more details

See E1050 CAN CONNECTION LINES

), controlling the switching on of the "side lights", "lights system failure" warning light. In addition the instrument panel signals the activation time for the follow me home function through an LCD.
