THE CONFORMITY CHECKING
Next, the checking of different states and configurations of the anti starting system is to be
performed.
In case of finding some failures at the diagnostic by means of
RECOMMENDATION the CLIP tester, analyse them based on the diagnostic (ALP)
corresponding to the respective failure.

THE PIN CODE
The PIN code is formed of four figures and it can be used only for deactivating the anti intrusion
s ystem, if this operation can not be performed by pushing the deactivating button from the RF
remote control of the vehicle. For introducing the PIN code, perform as follows:-set on the contact key in the M position and take it off it for three times in seven seconds,
after which the anti intrusion LED indicator will switch on for three seconds; -set on the contact again on the M position and maintain it until the number of the L ED
blinks is e qual with the first figure of the PIN code, then take off the contact; -set on the contact in the M position and maintain it until the number of LED blinks is equal
w ith the second figure of the PIN code, then take off the contact;
-perform the above mentioned method in order to introduce the third and the fourth figure
of the PIN code;
-after that, the system is deactivated and the siren stops automatically;
- set on the contact again – the anti LED indicator must switch on, confirming in this way
that the c orrect introduction of the PIN code.
AT TENT ION
If it i s necessary the checking of the PIN code, t his will be pe rformed
only after al least 20 seconds have passed, since the anti intrusion ECU has been
connected to the vehicle’s wiring or since the connecting of t he vehicle’s battery.
The COBRA anti intrusion system can operate in t hree different modes (2,3 or 4).
For the Super Nova vehicles, the system has been programmed to work in the second operation
mode. If by mistake the PIN code was introduced in less than 20 seconds since the battery
connecting or since connecting the anti intrusion ECU, this can involve the change of the operation
way of the system, which will generate errors during the operation. There is, although, the possibility
of reprogramming the correct operation way (type 2) and in this purpose, perform the following
operations : - disconnect and then reconnect the anti intrusion ECU; when connecting the anti intrusion
ECU the anti intrusion LED indicator will switch on once, confirming the correct connecting;
-af ter at least 5 seconds from the previous operation, but no more than 20 second from it,
perform the following operation s:
-s et on the contact key in the M position for three times and then release it;
- the anti intrusion LED indicator will switch on for three seconds and then will switch off;
- set on again the contact key in the “M” position and maintain it, counting two blinks of the
anti intrusion LED indicator, then take off the contact;
- the LED indicator will blink for two times in two series, confirming in this way the proper
performance of the previous operations;
press the doors locking button of the dashboard, in order to lock and unlock the doors; the anti
intrusion LED indicator must not blink;

Vo l u m etric protection checking.
Perform the following checking steps after locking using the RF remote control, the doors, the
engine hood and the hatchback. The operations must be performed in no more than 40 seconds
since the anti i ntrusion system has been activated with the RF remote control; if operating after
these 40 seconds, the siren will start and the turning lights will blink.
Close the door. The sound signal (buzzer)
will stop.
Th e pr oper operation of the anti intrusion system on different situations must be according to
those shown in Table 01. For detecting the causes of possible incidents of the anti intrusion system, perform the checking
steps presented in Table 02.
Lo wer the rear windows with about 10
cm. Close the doors, the engine hood
and the ha tchback.
Check out if there is any movement in
the cockpit.
Ac tivate the system pressing the button
of the RF remote control.
In troduce a hand through the window,
inside the cockpit and move it.
Th e LED indicator will blink quickly,
showing there has been a volumetric
detection and that volumetric sensors are
f unctioning correctly.
Deac tivate the system using the RF
remote contro l, then clos e al l the
vehicle windows.
Reactivate the system and then hit by
ha nd the windows surfa c e of the
vehicle. The LED indicator should
continue to normally blink and the siren
starting shall not occur.
Functional checking of the peripheral
protection.
Close the doors, the engine hood and the
hatchback.
Ac tivate the system pressing the button
of th e RF remote.
The doors will lock and the LED indicator
will blink.
Open a do or with the vehicle key.
The LED indicator will continuously be on,
a nd a sound signal (buzzer) will be heard.
Deac tivate and reactivate the sys tem
w ith the RF remote control.
Deac tivate t he system by pressing the
button of the RF remote control.
The do ors will unlock and t he LED
indicator will go off.
Rep eat a.m. operations for both front

If after a complete checking of the anti intrusion system,
the replacement of the E.C.U. anti
intrusion is required, proceed as follows:
- remove from the central console the tape recorder’s frame and the tape recorder pulling
backward but without disconnecting the tape recorder from the vehicle’s wiring;
- dismount by detaching the aeration grill located on the right side of the central console ;
- dismount the t wo screws attaching t he E CU support i n t he ri ght side of the climate
control unit;
- take off the anti intrusion ECU together with its support through the central zone of the
central console; - disconnect the 24 ways connector from the anti intrusion ECU proceeding as follows:
remove towards exterior the two blocking clips of the connector and then carefully pull out the
connector; - dismount carefully the two way connector from the anti intrusion ECU;
- dismount the two screw attaching the anti intrusion ECU on its support;
- proceed the in reverse order of the dismounting;
- check the proper operation of the anti intrusion system. DISMOUNTING – REMOUNTING

siren;
- connect to the siren the connector of the wiri ng, by pushing, until you hear a “click”
confirming the correct c onnecting, then mount the two attachment screws of the siren on the
