DESCRIPTION - COURTESY LIGHTS - Fiat GRANDE PUNTO 1.4 16v

The front courtesy light includes two lamps with three control pushbuttons: the pushbuttons can be used to turn on the corresponding light directly or in a timed manner, as described below.There is only one bulb in the rear courtesy light which can be switched on or off using the relevant switch or through a delay timer as described below.The courtesy light operation is timed according to a logic managed by the body computer:- when any door is opened, both the front spotlights and the rear courtesy light come on for 3 minutes. The timer is reactivated whenever the door is opened;- when all the doors are closed; the lights stay on for a further 10 seconds with the key off. This time is interrupted if the key is moved to key on position: in this case, the courtesy lights are turned off immediately.- When all the doors are closed at key-on the courtesy lights are immediately switched off.- when the key is extracted, both the front spotlights and the rear courtesy light are turned on and a 10 second timer is activated.- all the courtesy lights are turned off at the door lock control;- at the door release command, both the front spotlights and the rear courtesy light are turned on and a 10 second timer is activated.- If the inertia switch is operated the courtesy lights come on for 15 minutes.The switching on or off takes place gradually (dimmer) with the cycle lasting 2 seconds.The power supply to all the courtesy lights is governed by a battery voltage control logic: with the key off when any door or the boot is opened, a time of 15 seconds is set. After this, all the courtesy lights are deactivated.If one or more doors are open, this is shown on the instrument panel display; the warning light remain on until all the vehicle doors and boot lid are properly shut. If a given speed limit is exceeded, this is also signalled by means of a buzzer.

It is ignition-operated (INT) at pin 32 of connector D. Pin 10 of connector H of M1 supplies a reference earth to the Body Computer.Body Computer M1 is connected via the CAN line to instrument panel E50, to which it sends a signal that turns on the door open warning light, where necessary, and activates the buzzer to give an acoustic signal.
