NOTE
For the RF remote control synchronisation, after the replacement of an E.C.U.
decoder, the synchronisation procedure must be performed taking into account the
following situations: -for one RF re m ot e c ont ro l , pe rf orm t he “ SIMP L E SY NC H RONIS ED
PRO CEDURE”;
-f or the second RF remote control perform the “SPECIFIC SYNCHRONISED
PRO CEDURE”.
B. KIT REPLACEMENT PROCEDURE(E.C.U. decoder plus 2 key he ads)
In case of one kit replacement perform the following steps:
- memorising the anti starting code by the E.C.U. decoder
- memorising of the new anti starting code by the injection computer; i t is necessary the
repairing code (found out based on the old ke y heads code) and t he CLIP tester.
Perform the actions in the following sequence:
1. Mount the metal insertions of the old keys to the new key heads.
2. Send to Tech Line the key heads code, written on the vehicle invoice, in order to get the
repairing code. 3. Connect the CLIP tester to the diagnostic socket and to the battery (or t o the lighter
socket) of the vehicle. Read the configuration of the old E.C.U. decoder before dismounting off
the vehicle, as follows: - select vehicle type “SUPERNOVA” and the “050” equipping level;
- enter the menu “ COMPUTER TEST” then choose “ ANTI STARTING”;
- access “COMMAND MODE” then “READ CONFIGURATIONS”;
- note the configurations : petrol/diesel, programming with 1 or 2 keys, ceiling delay, the
type of the doors’ blocking switch (CPE), etc.;
4. Get back to the m enu “ANTI STARTING”;
5. Dismount the old E.C.U. decoder and replace it with a new one, the contact being off.
6. Check the configuration of the new E.C.U. decoder selecting “ STATE LIST”; here you
must find the following states: 18G FIRST CYCLE MEMORISINGPASSIVE…………………INACTIVE
19G NOT PERFORMED KEY PROGRAMMING ……………….ACTIVE
19D UNLOCKED KEY PROGRAMMING ………………………ACTIVE
NOTE
If the state 19G and 19D are not “ACTIVE” this m eans the E.C.U. decoder isn’t a
n ew one and cannot memorise another anti starting c ode. PROCEDURES

10. Take off the contact. In t he menu “COMMAND MODE” select “ACTUATORS” and
validate “ FINISHED CALIBRATION” launching the command on the blue rectangle situated
on the right top of the screen. The message “COMMAND IN PROGRESS” will appear,
followed by “ FINISHED COMMAND”. 11 . The anti starting indicator will blink rarely.
12. Get back to the “ STAT E LIST”, which now must be as follows: 18G FIRST CYCLE MEMORISING……………………………... ACTIVE
19G NOT PERFORMED KEY PROGRAMMING……………… PASSIVE
19D UNLOCKED KEY PROGRAMMING………………………PASSIVE
13. In the m enu “COMMAND MODE” choose “ ACTUATORS”. Select the command “
FORCED PROTECTION MODE” launching the command from the blue button situated on
the ri ght topside of the screen. The display will show “COMMAND IN PROGRESS” and
then “FINISHED COMMAND”. Get back to t he “STATE LIST “ and check the state:
9G FORCED PROTECTION MODE …………………………….. ACTIVE
14. Set the contact on “M” position. The anti starting indicator will start to blink rapidly. Check
in the “ STATE LIST” if the state “ANTI STARTING” is “ACTIVE”.
15. In the menu “COMMAND MODE” access “ACTUA TORS”, then select the command “
MANUAL INTRODUCTI ON CODE”. Type the four figures of the repairing code, then validate
with the key “ENTER”. On the screen the message “COMMAND IN PROGRESS” will
appear and then “FINISHED COMMAND”. 16. Take off and then set again the contact, without starting the engine, in order to send the
new anti starting code to the injection computer. The anti starting indicator will light for 3 seconds,
and then it will turn off.

For the RF remote control synchronisation, after the replacement of a kit, take into
account the fol lowing situations: - for the first RF remote control, perform the “ simple synchronised procedure”;
- for the second RF remote c ontrol perform the “specific synchronised procedure” .
C. CODE REPAIRING INTRODUCTION PROCEDURE
The repairing code may be introduced only by the means of the CLIP tester. This is possible
only if when setting the contact on, the anti starting indicator blinks rapidly, this being confirmed
by the state: 10G ANTI STARTING…………………………………………….. ACTIVE
After getting from DACIA database the repairing code (based on the code from the vehicle’s
key head), perform the following operations. 1. Connect the CLIP tester to the diagnostic socket and to the battery (or to the lighter
socket) of the vehicle. 2. The anti start up indicator must blink slowly , the contact being taken off.
3. Set the contact in “M” position. The indicator must blink rapidly.
4. Select vehicle type “SUPERNOVA” and “050” equipping level.
5. Select the menu “ COMPUTER TEST” then choose “ ANTI STARTING”.
6. In the menu “ STAT E L IST” find t he state 10G “ANTI STARTING” which m ust be
“ACTIVE”.
7. Access “COMMAND MODE” then select “ACTUATORS”.
8. Select the command “ MANUAL INTRODUCTION CODE” where you will write the
repairing code (formed of four figures), then validate it with the key “ENTER”. T he message
“COMMAND IN PROGRESS” will be displayed followed by the message “FINISHED
COMMAND”.
9. Now the procedure is finished and you may start the vehicle engine.
AT TENT ION
You may perform three essays of introducing the repairing code; if aft er the third
essay the code is not yet valid, wait for 15 minutes, take off the contact and then put it
again, other t hree essays being allowed.
NOTE
This procedure does not decode the injection computer, but allows only the start of
the vehicle’s engine. After ten minutes have passed from the first introduction of the
r epairing code or after the disconnection of the battery, the vehicle’s engine cannot be
s tarted unless a new repairing code is introduced. 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

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 anti intrusio
n system may be activated or deactivated by pushing the button of the RF remote
control of the vehicle key and it is achieving the peripheral protection of the vehicle and the volumetric
protectio n of the cockpit. The activation of the system is indicated on the instru ment panel by the LED
indicator, which will start to blink, and is confirmed by two blinks of the turning lights. Deactivation is
confirmed by a blink of the turning lights and LED indicator switching off.
In case of the vehicles equipped with central locking system, the doors will lock when the system
is activated and will unlock when deactivating the anti intrusion system. After 40 seconds from
remote control activatio n, the opening of a door, of the hood or the hatchback will cause the siren
starting and turning lights blinking for 30 seconds; after 30 seconds, the system remains activated.
During those 40 seconds, the volumetric sensors will “read” the volume of the cockpit, this
“reading” being reinitialised on every activation of the system, in order to take into account the
potential volume modifications. Any modifications of the inner volume of the cockpit ( broken
w indow glass, intrusion in the cockpit or movement inside the cockpit) will perturb the ultra-
sound emission field causing the siren starting.
The system does not normally operate unless all doors, the engine hood, the hatchback and
the window glasses are properly closed. If one of the front doors, the engine hood or the hatchback
is not well c losed, at the doors locking with the RF remote c ontrol, the t urning lights will not
switch on at all. At the deactivation with RF remote control, the traffic indicators will switch on,
just once.
AT TENT ION
In case of one door opening by key, while the anti intrusion system is
activated, the siren will start and it can be stopped by pressing the remote button or by
introducing the PIN code which is written on the vehicle invoice.
