DESCRIPTION - COURTESY LIGHTS - Fiat 500 1.4 16v

There is only one bulb in the front 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: Specifically:when any of the doors is opened it comes on for around 3 minutes. The timer is reactivated each time a door is opened;when all the doors are closed, with the ignition OFF, the light stays on for a further 10 seconds. This time is interrupted if the key is turned to the ON position: in this case, the courtesy light is turned off immediately;when all the doors are closed with the ignition ON the courtesy light is immediately switched off;when the key is removed, the courtesy light comes on and a 10 second timer is activated;the courtesy light is turned off immediately when there is a door locking command from the key or remote control (if present);at the door unlocking command from the key or remote control (if present), the courtesy light is turned on and a 10 second timer is activated.The switching on or off of the courtesy light takes place gradually (dimmer) with the cycle lasting 2 seconds.This vehicle does not have an inertia switch; the fuel cut off function is managed by the Air Bag control unit which, after detecting an impact, sends the FPS signal (Fire Prevention System) via the network activating the front courtesy light for 15 minutes.On versions not equipped with central locking, the activation of the courtesy light is not timed and is managed directly by the button or when the driver''s door is opened.The power supply for the courtesy light is governed by a battery voltage control logic (known as “SBMT”): the Body Computer continuously acquires the battery voltage signal and compares it with its own limit value.In Key-Off conditions and when any one of the doors or the boot is opened, a timed period of 15 minutes is set; all the lights are deactivated after this delay period.

FUNCTIONAL DESCRIPTION - COURTESY LIGHTS - Fiat 500 1.4 16v

The switching on of the front courtesy light G010 is managed by the Body Computer M001 which receives negative "door open" input signals respectively:at pin 54 of connector B (driver''s front door, via the internal contact at the geared motor N050 - pin 5 -);at pin 53 of connector B (passenger front door, via the internal contact at the geared motor N051 - pin 5 -).The front courtesy light G010 receives a power supply (pin 2) via the line protected by fuse F32 of the Body Computer M001 (pin 13 of connector F).The Body Computer supplies the other courtesy lights in the vehicle from pins 26 and 28 of connector F.The front courtesy light G010 is connected, via pin 1, to the left front erath C010 and, via pin 3, to pin 9 of connector F of the Body Computer M001, which provides a suitable negative signal for the timed/dimmed switching on/off.On versions without central locking the courtesy light is activated when the driver''s door is opened: when the N.A. contact for the switch on the door I016 is closed, pin 3 of the courtesy light G010 is connected directly to the left front earth C010. There is no timer delay on this version.The Body Computer M001 receives a direct battery power supply (pin 1 of connector A) protected by fuse F01 of the engine compartment junction unit B001 (pin 18 of connector B); it also receives an ignition-controlled power supply (INT) at pin 11 of connector E.The Body Computer M001 is also connected to the driver''s dashboard earth C015 via pins 9 and 10 of connector E.
