The replacement (repara tion) operations of t he weldable elements descri bed i n t his
chapter a re specified subject to: cutting out of t he parts t o be replaced; the a ccess to the
welded elements, tools and checking devices accessibility, etc.
In case the vehicle body has suffered import ant deform ations it is recommended the
str aightening of t he damaged body elements, by means of some hydraulic pre sses, the
operation being performed slowly and at cold. For this range of vehicles, the e lements re sistance structure which a re a ffecting the
vehicle securi ty, are not to be partially re placed ( not to be cut), but entirely.
After welding detaching, the body elements must remain stra ight, without breakage or
cracks, the possible holes being covere d out with filling material or by tinning. The body
elements surfaces are t o be pickled ( to eliminate possible oxidation marks) , dried and
initially applied a paint layer. The electric welding detaching of the body elements, is performed as follows:
- with a well sharpen chisel, this method may lead to part s deformation or even
parts breaking.
- by using some extractors equipped with steel cutter type Bre ndeo or Pickvant
max. 6 mm, having the cutting head as per shape shown in pict.1.
1. Centeri ng point
2. Sharpen slope
3. Drill acting edges
4. Gap for catching the welding materialP = aprox. 0.4 mm
Whatever method is used, the remaining element m ust be in good order a nd to allow
performing of a good quality welding point.
The pl ates cutting it is recommended t o be pe rformed ( subject of importance and thick-
ness ) using manual scissors or pneumatic portable tools for plates cutting.
Du ring cutting or welding of the body elements it is necessary to protect the electric
wir ing from the interi or of the body structure.
The cutting, welding, or strengthening operation done on body welded elements, are to
be performed on body checking/ straightening bench type CELETTE .
IMP ORTANT
When removing or straightening the body resistance e lements i t i s forbidden t he
total or partial heating, in order to avoid the mechanical resistance and metal elasticity

ECU DECODER REPLACEMENT PROCEDURE AND ANTI STARTING
CODE MEMORISING
The new E.C.U. decoder is always not coded. After its mounting on the vehicle it is necessary
that this one is memorising the anti starting code in order to be operational.
NOTE
If only the E.C.U. decoder i s replaced, there i s no need of an i ntervention to t he
E.C.U. injection (injection computer), which will keep the old anti starting code.
AT TENT ION
After the E.C.U. de coder memorised the anti starting c ode, this code cannot be erased
or replaced with another one.
In order t o perform this procedure, one of the keys of t he ve hicle and the CLIP tester are
needed. Perform as follows: 1. Connect the CLIP tester to the diagnostic socket and to the battery (or the lighter
socket) of the vehicle. 2. Read the configuration of the old E.C.U. decoder in the following way, before dismounting
it from the vehicle:
- select t he type “SUPERNOVA” and the “050” equipping level;
- enter the menu “ COMPUTER TEST” then choose “ ANTI STARTING”
- access “COMMAND MODE” then “CONFIGURATIONS READING”
- note the configurations found : petrol/d iesel, programming with 1 or 2 keys, ceiling delay,
the type of the doors’ blocking switch (CPE), etc.;
3. Get back to the m enu “TEST COMPUTERS”
4. Remove the old E .C.U. decoder and replace it with a new one, the contact being off.
5. Enter the menu “ANTI STARTING”, then select “ STATE LIST”. If the E.C.U. decoder
is new, you must find the following states:
18G FIRST CYCLE MEMORISING………………........................ ACTIVE
19G NOT PERFORMED KEY PROGRAMMING……………….. ACTIVE
19D UNLOCKED KEY PROGRAMMING………………............. ACTIVE
OBSERVAT ION
If the states 19G and 19D are not “ACTIVE” this means the E.C.U. decoder has
been already used, so it isn’t new and cannot memorise another anti starting code.
Access the menu “COMMAND MODE” and then “CONFIGURA TION”, where you will
configure the new E.C.U. decoder in the same way as the old one: petrol, 1 key, ceiling delay,
impulsion doors blocking switch, etc. selecting one by one these configurations, which you’ll
validate with “CLICK” on the blue button on right top of the screen. PROCEDURES

D. SIMPLE S
YNCHRONISED PROCEDURE
This procedure allows the synchronisation of a RF remote control with E.C.U. decoder and
is to be applied in the following situations:
- the RF remote control c ode is no longer i n the range of the E.C.U. decoder re ception,
because of consecutive pushing over a 1000 time on the RF remote control button.;
- the replacement of the E.C.U. decoder with a new one;
- the replacement of the RF remote control if the E.C.U. decoder is new (E.C.U. decoder
replacement plus a RF key.)
The following operations will be performed: - take off t he contact
- push and maintain like that for about 5 seconds, the doors locking switch located on the
dashboard ; the doors actuators are performing a closing/opening course.
- during the next 10 seconds, confirmed by the permanent lightening of the anti starting
system indicator, push twice the RF remote control button; the doors actuators are performing a
closing/o pening course.
- the procedure of synchronisation is finished; check the blocking/ unlocking by pushing
the RF remote control.
OBSERVAT ION
Duri ng those 10 seconds you can visualise by means of the CLIP tester the state 17G
“THE PROGRAMMING IN PROGRESS OR THE TIR/TRF
RESYNCHRONISATION” which must be ACTIVE.
E. SPECIFIC SYNCHRONISED PROCEDURE
This procedure is used for the synchronisation of the second RF key with E .C.U. decoder
and will be performed as follows:
- connect the CLIP tester to the diagnostic socket and the battery (or the lighter socket) of
the vehicle. - select the vehicle type “SUPERNOVA” and the “050” equipping level;
- select the m enu “ COMPUTERS TEST” then “ ANTI STARTING”
- enter the m enu “COMMAND MODE” and select “CONFIGURATION”
- validate the command “ PROGRAMMI NG THE SECOND TIR / TRF KEY” launching
the command from the blue button situated on the right top of the screen; the doors actuators are
performing a closing/opening course.
- during the next 10 seconds, confirmed by the permanent lightening of the anti starting
system, push twice the RF remote control button; the doors will block and then unlock and the
anti starting indicator will t urn off. The second remote control is now synchronised. Check the
blocking/ unlocking by pushing the RF remote control. PROCEDURES

GENERALITIES
DESCRIPTION
The a nti intrusion system has t he purpose of peripheral prot ection of the ve hicle a nd the
volumetric protecti on of the passengers compartment (cockpit) and has the following components:
The ECU anti intrusion (1) is located under the central console, being attached under the
climate control unit and receives information from the volumetric sensors and from the contacts
of: front doors, engine hood and tail hatchback.
In case of an intrusion into the vehicle, when the system is activated, ECU will start t he siren
combined with intermittent lightening of the turning lamps.
The volumetric sensors (2) are fixed on the upholstery of the left and right upper part of the
pillars. After the activation of the anti intrusion system with the remote control, the sensors c an
supply information to the ECU concerning the interior volume of the cockpit, which, in case of its
modification will produce the siren starting and the intermittent lightening of the turning lamps.
The siren (3) is fixed on a frame, being located in the climate control unit and it is controlled by
the ECU anti intrusion.
The intrusion LED indicator (4) is located on the dashboard, on the left side and it indicates if
the system is activated or not and in case of an aggression on the vehicle, the indicator will show
the type of aggression.
The contacts of the front and rear doors (5), of the e ngine hood (6) a nd of the hatchback (7)
are supplying information concerning their opening, to the ECU anti intrusion, when the system is
activated.

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;
