The vehicle is equipped with an extra- bright red rear fog lamp located in the rear bumper on the left (on the right on right hand drive versions).

The rear fog lamp is activated via the dedicated button in the controls to the left of the steering wheel; when the light is on, the warning light in the instrument panel comes on.

The switching on of the rear fog lamp is managed by the Body Computer; it is activated by:

- key to ON enablement signal (INT);

- a control signal coming from the switch;

- dipped headlights or fog lights on signal.

If the dipped headlights or the fog lights are turned off, the rear fog lamp is deactivated even if the operating button is still pressed. When the lights are switched on again, the rear fog lamp does not come on automatically, but only when the button is pressed again.

If the key is switched off (OFF position) and then switched back to the MAR (ON) position M, the button must be activated again to turn on the fog lights.

The rear fog lamps check function checks that the light is working properly: the following are checked:

- open circuit or missing bulb

- short circuit to earth (bulb s.c. or wiring s.c. to earth)

- short circuit to battery voltage (wiring short circuited to Vbatt)

When one of the situations described above is verified, the Body Computer makes the failure status available to the CAN: a special "lights failure" warning light comes on in the instrument panel and, at the same time, the information is shown in the display.

The (earth) signal activating the rear fog lamp reaches pin 45 of connector D of M001 from the control button in the panel to the left of the steering wheel H091 - pin 7.

The connection with the Body Computer for the fog lights and rear fog lamps activation signal is the same. They are connected at pin 45 of connector D of M001, but the signal is different because the resistance values in series with the two different switches located in the control panel H091 are different.

The reference earth reaches pin 1 of H091 from pin 37 of connector D of M001.

The Body Computer M001 - connector A - receives a direct powr supply from the battery through the line protected by maxi fuse F01 of the engine compartment junction unit B001.

The Body Computer M001 receives an ignition-controlled power supply (INT) at pin 11 of connector E.

Pin 9 of connector E of M001 provides the Body Computer with a reference earth.

The dipped headlamps activation signal is sent to pin 38 of connector D of the M001 from the steering column switch unit H005.

The Body Computer M001 controls the power supply for the rear fog lamp F033 from pin 60 of connector F.

The Body Computer M001 is connected via the CAN line to the instrument panel E050 to manage the "fog lamps on" warning light and the "lights failure" warning light.
