FOG LIGHTS - FUNCTIONAL DESCRIPTION

FUNCTIONAL DESCRIPTION

The (earth) activation signal for the rear fog lamps reaches pin 30 of connector D of M1 from the control button in the panel to the left of the steering wheel H91.

The reference earth reaches pin 1 of H91 from pin 42 of connector D of M1.

IBody Computer M1 - connector G - is supplied directly by the battery from a line protected by maxifuse F2 of engine compartment control unit B1; it is suppiled via the ignition (INT) at pin 32 of connector D; pin 10 of connector H of M1 supplies a reference earth to the Body Computer.

The side lights activation signal is sent to pin 38 of connector D of the Body Computer M1 from the steering column switch unit H5

See E2010 SIDE LIGHTS / NO. PLATE LIGHTS

3The Body Computer M1 controls the supply for the foglamps sending an earth signal to relay T14 in the junction unit in the engine compartment B1 from pin 3 of connector A of M1.

Relay T14 is in turn supplied by relay T5 of B1: this is an "ignition-operated except during start-up (INT/A)" supply controlled from pin 1 of connector A of M1.

This earth signal excites relay T14: this supplies left foglamps F15 and right foglamps F16 via a line protected by fuse F31 of control unit B1.

The Body Computer M1 is connected via the CAN line to the instrument panel E50 to manage the "fog lights on" warning light.
