DESCRIPTION - COURTESY LIGHTS - Alfa Romeo 159 1.9 JTD 8V Da 01/06
The front courtesy light includes three lamps with three control switches: it is possible to switch on the corresponding spot light using the outside buttons; the centre button switches the centre light on and off, which is also turned on with a timed delay as described below.There are two bulbs in the rear courtesy light which can be switched on or off using the relevant button or through a delay timer as described below.The courtesy light lighting delay is based on a logic managed by the Body Computer whilst the rear courtesy light is operated by the door control units in accordance with a logic transmitted by the Body Computer via the CAN:- Pressing the button in the front courtesy light operates both the front courtesy light and the rear courtesy light: in particular, with the courtesy lights off, both are switched on and, with the courtesy lights on, both are switched off.- When any of the doors is opened both the front and rear courtesy lights come on and there is a timed delay of 3 minutes which is reactivated each time a door is opened.- When, on the other hand, the button in the front courtesy light is pressed during the timed delay, the courtesy lights are switched off and the timed delay in progress is zeroed.- When all the doors are closed at the key-off (TEG extrated), the previous timed delay is zeroed and a 10 second timed delay is activated; (this delay is interrupted in the case of a key-on (insertion of the TEG).- When all the doors are closed at the key-on (insertion of the TEG) the courtesy lights are immediately switched off.- When the TEG is extracted both the front courtesy light and the rear courtesy light come on and a timed delay of 10 seconds is activated.- Both the front and rear courtesy lights go out on the "door locking" command.- Both the front courtesy light and the rear courtesy light come on on the "door unlocking" command and a timed delay of 10 seconds 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.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.
FUNCTIONAL DESCRIPTION - COURTESY LIGHTS - Alfa Romeo 159 1.9 JTD 8V Da 01/06
The Body Computer M1 receives "door open" input signals at pin 8 (driver''s front door) and pin 16 of connector D (left rear door) and at pin 25 (front passenger door) and pin 26 of connector E (right rear door).Both the front courtesy light G10 and the rear courtesy light G20 receive a power supply from the direct line protected by fuse F39 of the junction unit under the dashboard B2.The front courtesy light G10 is controlled by the Body Computer M1 : the analogue control signal from the three courtesy light buttons reaches pin 28 of connector E of M1 : the Body Computer M1 consequently supplies the courtesy lights G10, providing a timed earth signal from pins 21, 30 and 37.The rear courtesy light G20 is controlled by the driver''s door control unit M66 and the passenger door control unit M67: the control signal from the buttons on the courtesy light reach pin 12 of connector B, whilst a power supply is sent from pin 14 to the lights G20.The Body Computer M1 is connected, via the CAN line, to the instrument panel E50 from which it receives the "inertia switch operated" signal that lights up the courtesy lights and to which a signal that lights up the "doors open" warning light, when necessary, is sent.
