DescriptionThe vehicle is fitted with an extra bright rear fog lamp, located in the left rear light cluster which can be used in all poor visibility conditions.The rear fog lamp is activated through the special button in the switch unit in the centre of the dashboard; the button is dimly lit when the ignition is switched ON and becomes much brighter when the actual light is switched on.The rear fog lamps are enabled when the dipped beams are on, or when the fog lamps are on.This control logic is managed by a special electronic device located in the switch unit.
Functional description The electronic device located inside the switch unit H90 controls the rear fog lamps circuit. The button - in the actual unit H90 - sends the operating signal to this device, which receives the supply controlled by the ignition INT (pin 6 for connector A of H90 ) from the line protected by fuse F8 of the junction unit B1 . The device only controls the supply of the rear fog lamp (from pin 7 of connector A) in the right rear light cluster F30 (pin 5) if one of the two go ahead signals from the dipped headlamps or the fog lamps arrives. The first signal (dipped headlamps on) arrives from the steering column switch unit H5 to pin 8 of connector A: it is a supply controlled by the ignition (INT) for the line protected by fuse F8 of the junction unit B1 . The second signal (fog lamps on) is supplied by the internal circuit for the unit H90 . With the rear fog lamps switched on, a signal also lights up the control button. The entire control unit H90 is lit when the ignition is switched on (INT/A) by the line (pin 5 of connector A) protected by fuse B27 .
