DIPPED HEADLAMPS - Functional description

Functional description

The low beam activation control is issued by stalk unit H005 by turning lever unit A and B (both switches perform the same synchronous movement) to position 2..

Body computer node M001:

• receives a negative signal ( relating to earth C020) at pin 2 (side lights) and pin 7 (high beams) connector P.

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

When the signal has been received, it turns on the side lights (see wiring diagram E2010) and low beams.

• from pins 7 and 8 connector B, it supplies the low beams housed in the front light clusters F010 and F011;

Both lines are protected by fuses F13 (left branch) and F12 (right branch) containedin the body computer node.

Supply lines protected by fuses F12, F13 are controlled by a relay housed in the body computer node.

The follow me home function is activated by stalk unit H005, via key D (light flasher).

Body computer node M001:

• receives a negative signal ( relating to earth C020 connector B) at pin 5 connector P See E2012 MAIN BEAM HEADLAMPS.

Once it has received the signal, it turns on the low beams:

• from pins 7 and 8 of connector B, it supplies the low beams housed in front light clusters F010 and F011;

Pressing lever unit D (light flasher) for longer than two seconds deactivates the function.

From pins 35, 36 connector I, the body computer comunicates the instrument panel E050 via the CAN network (seei See E1050 CAN CONNECTION LINES for more details and turns on the side lights light system failure warning light. The instrument panel also indicates the follow me home function activation time by means of an LCD display.
