Operation

When the push-button on the remote-control key is activated, this is signalled by the LED on the key itself, and a radio-frequency

(RF) signal is sent to the ECU. This signal controls closing of the doors by means of the motors, activates the volumetric sensor

installed in the ceiling-lamp inside the cab and signals that the anti-theft protection has been activated by causing the indicator

flashing lights to flash twice and the "anti-theft activated" LED to flash once. About ten seconds pass between the time when

the signal is sent to the ECU and when the system is actually active. During this period of time, the ECU checks that all the

necessary conditions (state of the doors, inside of the cab) for activating the anti-theft protection are met. Once the 10 seconds

have elapsed the system is active and is constantly checked by the ECU.
If the ECU does not find all the conditions required for correct activation of the system while it carries out the anti-theft activation

procedure (for example, if one of the doors is not closed), the state of the door will not be checked during the system monitoring

that the ECU carries out upon completion of the activation procedure. Once the door has been closed, this too will be checked

by the ECU, starting ten seconds from the time when it was closed.
The conditions in which the anti-theft protection switches on are the following:
- if the driver's/passsenger's doors are opened
- if the rear door is opened
- if the bonnet is opened
- if the side door(s) is(are) opened
- if the engine is switched on
- if the volumetric detection module is activated.
If any of the above conditions occur, the sound of the self-powered siren and the flashing of the indicator flashing lights for five

minutes will signal that the system has switched on.
In order to be able to open the doors and de-activate/switch off the anti-theft protection, it is necessary to press the push button

on the remote-control key again. The ECU will de-activate the anti-theft protection. The indicator flashing lights will flash once

and the signalling LED of the anti-theft protection will go off to confirm that it has been de-activated.

MAIN COMPONENTS OF THE SYSTEM
Remote-control key

The electronic device controlling the anti-theft protection with the door-blocker can be mounted in the grip of the key or in

any suitable place for the remote-control function.
Features:
- transmission frequency 433.92 MHz
- transmission of combined code (fixed and variable)
- red LED for signalling transmission of the code
- 3V CR 2032 battery
- operation from -30 °C to +60 °C
- retention of the rolling-code" data (variable part of the combined code) in the memory of the microprocessor in the key

during replacement of the battery

- maximum power transmitted: 10 mW.
On pressing the push button in the key, all the doors will be opened or closed and the anti-theft protection will be activated

or de-activated. The red LED on the key will flash to signal transmission of the radio-frequency code to the ECU. If the pushbutton

is activated for a time exceeding 20 minutes, transmission of the code to the ECU will be broken off, in order to prevent the

battery of the remote-control key from going dead due to accidental activation of the push button.
As already stated, the remote-control key transmits a combined code (fixed and variable). The fixed code that is transmitted

is always the same for each individual key, while the second part changes each time the pushbutton is pressed.
The keys supplied are two. It is important that they should both follow the correct key-learning procedure by means of the IVECO

diagnostic tools with the +15 power supply on. The indicator flashing lights will flash once to signal that the code has been received

by the ECU.
If the remote-control key gets partly or totally damaged, with the +15 power supply on, the immobiliser will send a signal to

the ECU to de-activate it.
If the exchange of data between the transponder and the engine management is successfully completed, the immobiliser will send

a 500 msec ± 10 % message to the ECU. This signal will occur after 500 msec ± 10 % from when the +15 power supply is switched

on. If it is not, that is to say if the immobiliser signal does not fall within the range of values indicated above, the ECU will switch

on the anti-theft protection. The impulses generated by the immobiliser after repeated switching on of the +15 power supply

will be ignored.
