Autodiagnosis
When switched on the system carries out an autodiagnosis which can be recognized by the LED flash­
ing at 4 Hz and if there is a problem or fault in the system, the LED will signal it in accordance with the
methods described in table 1.
Table 1. Autodiagnosis display
BLINK CODES
8 Hz, duration 2.5 sees
Light constant, duration 2.5 sees
MEANING
Door/bonnet/boot left open or switch faulty
Volumetric sensors faulty
If a fault is detected for the volumetric sensors, then the appropriate sensor is excluded from the surveil­
lance and an audible warning signal (beep) is emitted a second after switching on.
When it is switched off, the system indicates, via the flashing of the LED, which sensor has set off the
alarm during the surveillance (see table 2).

The blink codes are given in order.
These codes have an interval of 1.5 seconds between them.
Manual diagnosis
It is also possible to carry out a MANUAL DIAGNOSIS by opening the lid and turning the ignition key
from the ON position to the OFF position; the lid protective button must be pressed within 15 seconds 7
times in rapid succession in less than 10 seconds; 5 beeps will signal the start of the manual diagnosis
procedure. After 10 seconds the LED or the direction indicators will flash once.
By entering into this mode the autodiagnostic procedure for the volumetric sensors connected to the
control unit will automatically be activated.
If the test does not indicate, irregularities, then the direction indicators will flash 3 times and there will be
3 beeps of the alarm.
After this first stage, each time the state of the switches is altered there will be a corresponding quick
flash of the direction indicators and a beep, accompanied by the LED in the centre console flashing.
If the key is turned to the ON position, the alarm will sound briefly (500 msecs) and the direction indica­
tors will flash (2.5 sees).
This last operation indicates the exit from manual diagnosis procedure. It is also possible to leave the
MANUAL DIAGNOSIS by not carrying out any actions for 30 seconds: the exit is signalled by the direc­
tion indicators coming on for around 2.5 sees and a beep.
