for the van version, the loading platform. They send the signal indicating the status of the doors and of the bonnet to the ECU.
Door-blocker/unblocker motors
Each door has its own motor for closing/opening the lock on the door.
Operation  of  the  motor  is  enabled  by  switching  the  remote-control  switches  on the circuit card of the ECU on/off for a

pre-established period of time, programmable in the EEPROM of the ECY.
These motors can be activated in two different ways:
- by means of the pushbutton on the remote-control key (blocking/unblocking of all the doors)
- - by means of the switch on the switch panel (blocking/unblocking of the rear door only, in the van version).
With the +15 power supply on, operation of the motors by pressing the pushbutton on the remote-control key is not possible.

Activation of the motor of the rear door by means of the switch on the switch panel is possible, on the other hand, regardless

of the presence or otherwise of the +15 power supply.

Base - May 2004

This module carries out volumetric detection inside the cab, by means of the two sensors located on the sides of the ceiling-light

(A) inside the cab, starting from when the anti-theft protection is activated. It sends the data to the ECU. Any changes in the

state inside the cab due, for example, to the windows being smashed or an object being accidentally moved, will be transmitted

to the ECU, which will command the anti-theft protection to switch on.
The module includes a LED for signalling that the anti-theft protection has been switched on. This is also mounted in the

ceiling-light inside the cab (B), and in addition to the state of the anti-theft protection (active, inactive), it also signals that key

learning has been accomplished and any failures in the system.

Siren

The siren is located inside the engine compartment. It is self-powered by an internal battery that enables it to sound when it

is disconnected from the vehicle, and it must comply with specific requisites, such as supplying a value greater than or equal to

100 dB at a distance of 1 metre from the siren after 5 minutes of operation.
The batteries of the siren are recharged in the following ways:
- trickle-charging
- rapid charging
- charging after disconnecting the siren from the vehicle
Trickle-charging is always activated in order to compensate  for the normally occurring loss of charge of the batteries. The

batteries will be charged by supplying a 12 mA current for one minute at intervals of one hour.
Rapid charging takes place for a duration of 14 hours with a current of 12 mA. This method is used when the siren is connected

for the first time, or when it is reconnected to the system following maintenance operations on the vehicle that require the battery

to be disconnected. Once the required time has elapsed, charging stops. This type of charging does not require the +15 power

supply to be on.
With the third type of charging, if the siren of the vehicle is disconnected while it is not sounding, the whole time for which it

remains disconnected will be the same required to recharge the batteries when it is connected to the system again. If, on the

other hand, the siren is disconnected after it has been triggered, when it has to be reconnected to the system the batteries will

be charged for 45 seconds for each second that the siren remained disconnected. This recharging process is only carried out

with the +15 power supply off. If the batteries are below the minimum charging level, they will be recharged, with the +15 power

supply on, for 14 hours at 12 mA.
