Description - ALARM - Fiat DUCATO 2.3 JTD 16V fino a 02/05

The alarm system offers volume-sensing and perimeter protection against intrusion into the vehicle.A dedicated control unit monitors the following:the state of the doors and lids, via switches in the catches (perimeter control)the presence of a moving object inside the passenger compartment, by means of volume-sensing sensor (volumetric control)the condition of the system supply leads;operation of the ignition switch.The control unit is equipped with a self-diagnostic function which detects and memorises faults and problems in the control unit and system components; in addition, it checks the condition of the connecting cables and saves the number of activations and times the alarm has been operated.The control unit operating strategy can be modified in order to satisfy the legal requirements which govern the use of alarm systems in the various markets.The door lock system switches are used to monitor the doors and boot.A special separate switch detects bonnet closure.The volumetric sensors check for intrusions into the vehicle. They are located in the front courtesy light: they consist of a transmitter and a receiver: the wave transmitted by one transmitter must reach the receiver of the other sensor and viceversa: otherwise an alarm signal is sent to the control unit.The function may be activated/deactivated by pressing a key next to the sensors: when the sensors are excluded, a led next to the button is turned onSystem activation is displayed by means of a special deterrent led.

Operational Description - ALARM - Fiat DUCATO 2.3 JTD 16V fino a 02/05

The alarm system is fully managed by alarm control unit M030. The control unit receives an ignition-operated supply protected by fuse F27 - located in underfacia control unit B002 - and a direct battery supply protected by fuses F60 and F34 - located in optional junction unit B101 -.The control unit comprises two connectors, A and B, with the following pin-outs:Connector A:pin 1 : deterrent Led activation/deactivation;pin 3 : battery supply;pin 4 : system deactivation from remote key I100 - pin 1 connector B -;pin 7 : system activation from remote key I100 - pin 2 connector B -;pin 8 : volumetric sensor power supply K062 - pin 1 -;pin 9 : earth connection C010 - pin 10 -;pin 11 : earth reference for volumetric sensors K062 - pin 3 -;pin 12 : volumetric sensor power supply K062 - pin 2 -.Connector B:pin 1 : right turn signal power supply to control panel H090 - pin 7 connector A -;pin 2 : left turn signal power supply to control panel H090 - pin 5 connector A -;pin 7 : power supply direct from battery for controlling right and left turn signals;pin 8 : left front door open signal input from control panel H090 - pin 1 connector A -;pin 9 : right front door open signal input from control panel H090 - pin 1 connector A -;pin 12 : ignition-operated power supply;pin 13 : shared power supply for remote key I100 - pin 2 connector A -;pin 16 : right sliding door and door flaps open signal from control panel H090 - pin 6 connector A -;pin 18 : bonnet open signal input, from switch on bonnet I010 - pin 1 -;Remote control receiver M035 controls vehicle door catch closure/opening. More specifically, door unlocking is controlled from pin 5. The signal is distributed to the catches by short-circuiting junction D0971. Door locking is controlled from pin 6, distributed from short-circuiting junction D097G. Pin 3 receives a power supply directly from the battery while pin 7 receives an ignition-operated power supply.
