General description

GENERAL DESCRIPTION

Upon request the car is fitted with special halogen fog lights, while the high luminosity rear fog guard is a standard item. This is located in the rear light cluster on the lefthand side of the tailgate and it is necessary under low visibility conditions.

Thus the entire system ensures the best possible active and passive visibility under all circumstances. The fog lights are turned on by the switch on the dashboard inside the Check Panel, while the rear fog guard is turned on by the control on the lever unit. The fog lights can be turned on when the side lights are on, while the rear fog guard can be turned on only with the low beam headlights or fog lights on (they turn off when these are turned out) and, from Model Year '97, they must be turned on again the next time the engine is started (key at MARCIA).

A warning light on the instrument panel indicates that the fog lights are on and another one indicates that the rear fog guard is turned on. Each of the two circuits is protected by a fuse.

NOTE: The versions for some countries are fitted with "Daylights" i.e. side lights that always stay on when the ignition key is turned and a different logic for turning on the low beam lights, fog lights and rear fog guards. In this case, the present section should be considered complementary to the "Daylights" section which should therefore be consulted first.

FUNCTIONAL DESCRIPTION

Fog lights

The circuit for the fog lights is controlled by the corresponding relay switch I17 located in fuse box G1 (box "A" or "C") or near to it (box "B").

By operating the switch located in the Check Panel C16, with the side lights on (lever unit switch B68 in position "I") an earth is sent which energizes the coil of relay switch I17 thereby closing the circuit which sends the supply to the two fog lights E10a and E10b.

The steering column lever unit B68 is protected by fuse F15 in fusebox G1 - only for box "C".

The switch in C16 is lit by a led when the side lights are on.

The fog lights circuit is protected by fuse F19 of box G1 (box "A" or "C") or by an outside floating fuse G382 (box "B").

The supply line also sends a signal to the instrument cluster C10 to turn on the corresponding warning light.

Rear fog guard

- Up to Model Year '96

The circuit of the rear fog guard is controlled by the corresponding relay switch I25 located in fusebox G1. If the low beam headlights or the fog lights are on, through the switch on the lever unit (lever unit switch on position "II"), the supply and earth are sent to the coil of relay switch I25 thereby closing the circuit that sends the supply to the rear fog guard in E20. This consensus logic is carried out in the fusebox "A" by the connection inside the actual box, between pin 87 of I17 and pin 86 of I25. For box "B" there is a special relay switch I65, located near the box, which is energized when the fog lights are on, thus supplying relay switch I25 when the low beam lights or the fog lights are on.

The rear fog guard circuit is protected by fuse F11 in box G1.

The supply line also sends a signal to the instrument panel C10 to turn on the corresponding warning light.

- From Model Year '97

The rear fog guard circuit is controlled by device N25 to be found next to fusebox G1 (box "A" or "B") inside fusebox G1 (box "C").

Device N25 receives the "key-operated" supply at pin 6; pin 4 is earthed, while at pin 9, 3 and 1 it receives the control and enable signals, which are respectively: request to turn the lights on (by the special switch on the lever unit B68); fog lamps on (the same signal of the fog lamp warning light) and low beam headlights on (from lever unit B68); when the request to turn on the lights is accompanied by one of the two enable signals, device N25 closes the circuit on pin 8 which energises relay I25 (box "A" or "B"). For box "C" the line from pin 8, protected by fuse F11 of G1, supplies directly the lamp E20.

The device turns off the lights if it "loses" the "key-operated" signal; when the key is moved back to MARCIA, the reversing lights are turned on only pressing switch B68 again.
