activation when it is connected to the system.
Idle mode/state
This state indicates when the siren has been disconnected and its operating state has been blocked, implementing the siren service

mode described below. The siren is blocked in order to retain the charge of the batteries and its microprocessor is de-activated.

An acoustic signal produced by the siren will signal its activation when it is reconnected to the system.
Siren disabled state
The siren always goes into an idle state when it is connected to the vehicle on the IVECO production line. In addition, the siren

also goes into this state when the anti-theft protection is de-activated by the remote-control key.
Enabled state 1
This is the normal state of the siren, and it indicates that the anti-theft protection has not been activated and that the +15 power

supply is off. In this state, the siren can still trigger off an alarm if it is disconnected from the vehicle.
Enabled state 2
In this state, the anti-theft protection is activated. The siren has already received a serial activation command from the ECU. In

this state, if the siren is disconnected or the ECU detects a signal able to switch on the siren, this will be activated.
Alarm state 1
In this state the siren is on, however the ECU is not activated. The siren was activated because it was disconnected.
Alarm state 2
In this state the siren is on. The ECU is activated. The siren may have been caused to switch on by a signal from the ECU triggering

anti-theft protection or because it was disconnected from the battery of the vehicle.

ERROR CODES

Any faults and their causes are detected by the ECU and stored in it. There is a diagnostics system that enables them to be

identified, with the +15 power supply on, by detecting the number of times that the anti-theft signalling LED flashes. Correct

interpretation of the flashing will lead to identification of the number of the error code. In order to do this, it is necessary to know

that:
- the LED on for 1 second is equivalent to ten
- the LED on for 0.5 seconds is equivalent to one unit.
The time that passes between each time that the LED goes on and the next is 0.5 seconds. If two or more error codes should

be detected, the time for which the LED remains off would be 2 seconds.
The error codes are signalled, if the corresponding fault is present, once only and in ascending order. Then, once all the active

faults have been signalled, the LED will extinguish.

AIR SUSPENSIONS ECAS

High-flexibility air suspension system with highly efficient vibration damping effect provided with self-adjusting feature that keeps

constant chassis-to-road height, regardless of the load carried by the vehicle. A special push-button allows to change

chassis-to-road surface distance, that is the height of the vehicle cargo compartment floor.

Besides the traditional advantages of any air suspension system, the ECAS system also allows:
- air consumption reduction
- prompt response to adjustment
- simple systems
- high safety
- complete system diagnosis.
The ECAS (Electronically Controlled Air Suspension) system automatically controls the vehicle air suspension system nominal

level.
The features described above are bound to special operating and safety conditions of the associated systems.
The ECAS electronic control unit automatically checks chassis level (height from road surface) by reading the real values supplied

by the sensors and comparing them to the rated values stored in the memory.
With any change of the vehicle trimming, the electronic control unit controls the electropneumatic units to bring the actual level

to the level set or previously memorized by the driver.
