Description - REAR FOG LAMPS - Alfa Romeo GT 1.8 T.SPARK

The vehicle is equipped with a bright rear fog lamp located on the left side of the rear bumper (on right hand drive versions, it is located on the right hand side).The rear fog lamp is activated through a button in the centre console; an LED at the back of the button comes on when the light is switched on.The switching on of the rear fog lamp is managed by the Body Computer: it is activated by:enablement signal with key in ON position (INT);control signal coming from the switch in the panel;side lights on signal.headlamp signal (dipped or main beams), or fog lights on.If one of the enablement signals fails, the activating button must be pressed again to switch on the rear fog lamp.The rear fog lamp check function checks that the light is working properly: the following is check:open circuit (bulb missing or wiring broken) which can be diagnosed if there is no commandshort-circuit to earth (bulb s.c. or wiring s.c. to earth)short circuit to battery voltage (wiring short circuited to Vbatt)replacement of 21 W bulb with 5 W bulbIf one of the situations described above is detected, the Body Computer notifies the CAN of the failure state: the special ''lights failure'' warning light in the instrument panel comes on and, at the same time, the information is shown on the display.

The rear fog lamps activation signal reaches pin 35 of connector B of M1from the control button in the centre console H12.The side lights activation signal is sent to pin 28 of connector B of the Body Computer M1from the steering column switch unit H5.The dipped headlights activation signal is sent to pin 4 of connector D of the Body Computer M1from the steering column switch unit H5EL2011].The fog lights activation signal reaches pin 1 of connector D of the Body Computer M1(see EL2030].The ignition ON signal (INT) for the switch H1reaches the junction unit under the dashboard B2, at pin 11 of connector H, and from there reaches the Body Computer M1(pin 9 of connector F).The Body Computer M1controls the power supply for the rear fog light F32from pin 31 of connector E.From pin 21 of connector C of M1a signal is sent for lighting up the LED in the control button H12.Via the CAN line the Body Computer M1is connected to the instrument panel E50to manage the "lights failure" warning light if a failure is detected in the circuit.
