GENERALITIES
The anti starting bushing (picture 5) is located around the starting contact a nd is accessible
after the dismounting the steering wheel’s cases. It catches the signal from the key head and then
s ends a coded signal t o the E .C.U. decoder.
The vehicles equipped with RF remote control keys for blocking/ unlocking t he doors are
provided with another anti starting bushing which transmits to the E.C.U. decoder also the signal
received from the RF remote control.
The recognition of the two types of decoding bushings is realised by means of codes labelled
on their body, as follows :
- code 042264J - for vehicles w ithout RF remote control
- code 8200044257 - for vehicles with RF remote control
The E.C.U. decoder (picture 6) has the
following functions :
- decode the signal received from the anti
starting bushing ;
- sends a c ode to the injection computer
in order to authorise the engine starting.
- controls the anti starting indicator of the
instrument panel - receives the coded signal from the anti
NOTE
In case both keys we re lost, the code of the key head (8 characters) and the code of
the m etal insertion (4 characters) can be red from the vehicle invoice. If al so the i nvoice
was lost, the two mentioned codes can be found out based on the chassis series number
of that vehicle, accessing the database of the DACIA manufacturer, calling the TECH

NOTE :
The vehicles equipped with this anti starting system, have a type of decoder, and those
provided also with RF remote control for locking/ unlocking doors have another type
of decoder.
The identification of the two types of E.C.U. de coder i s realised by the inscriptions on
the labels as fol lows: -code P8200032783H and the inscription TRANS-PLAF for the vehicles without
RF remote control ;
-code P82000 32776H and the inscription TRF-TRANS-CAR for the vehicles
with RF remote control.
ANTI STARTING INDICATOR
It is located on the instrument panel (picture 8, position A) and has the following functions: - signals the activation of the anti starting system
- signals the case of non identifying the key head
- signals the entrance in the operation mode “resynchronisation” of the remote controls,
RF with E.C.U. decoder, for the vehicles which use the RF remote control.

GENERALITIES
The dome ceiling lighting is activated subject to the position of the switch
(picture 7, position 1):
- position A the ceiling lights permanently
- position B the ceiling turned off
- position C dome ceiling lighting; this will light for 5 seconds after a front door closing or
after the command of unlocking the doors with the RF remote control. This delay turns out in the
moment of setting the contact.

ter ordering a new key head based on the alphanumeric code mentioned on the i nvoice,
dismount the old key head and remove the metal insertion (mechanical part), then introduce the
old metal insertion in the new key head according to t he previously mentioned procedure. In
case the key head is provided with RF remote control for blocking/ unlocking the doors, after its
replacement, perform the synchronising procedure of the RF remote control with the decoder,
subject to the following cases:
(a)- the vehicle has a key with RF remote control and one without RF remote control; in this
case after the replacement of the RF key, perform the “simple synchronised procedure” in order
to bring into phase the RF remote control with the decoder.
( b)- the vehicle has two keys with RF remote control; after the replacement of one RF key,
perform the “specific synchronised procedure”;
(c)- the vehicle has two keys with RF remote control; if both keys are replaced, perform the
“simple s ynchronised procedure for the firs key and the “specific synchronised procedure” for
the second one. If a key was lost, a new key head and a metal insertion will be ordered. KEY HEAD REPLACEMENT

ll the new decoders, are not coded. After t he mounting on the vehicle it is necessary the
memori sation of t he key head code by the decoder i n order to be operational. If only the
decoder is replaced, no intervention is necessary to the injection computer, which will keep the
old anti starting code. When the vehicle is provided with RF remote control for blocking/unlocking
the doors, the performing of the resynchronisation of the keys with the decoder is imposed, after
its mounting.
If further to the diagnostic of the anti starting system, using the CLIP tester, the replacement of
the decoder is imposed, proceed as follows: - disconnect the front wiring connector from the E.C.U. decoder ( the contact being off);
- dismount the attachment screws of the E. C. U. decoder on the front left pillar;
- mount the new E.C.U. decoder;
- connect the front wiring to the new decoder.
Proceed then to the insertion of the anti starting code using the contact key, then to its memorising
(validation) in the E.C.U. decoder, using the CLIP tester. For this purpose, perform the “E.C.U.
decoder re placement procedure and a nti starting c ode memorising”. Che ck then the correct
operation of the anti starting system with both keys. E.C.U. DECODER REPLACEMENT

Once the decoder has memorised the key codes, this code cannot be erased
or replaced with another one.
If it is necessary the replacement of the kit (E.C.U. decoder and two key heads), after that
realise t he “ Kit replacement procedure”.

If further to the diagnostic, it is established
the necessity of the replacement of the anti starting
bushing, proceed as follows: -dismount the attachment screws of the steering wheel casing ;
- unlock the steering wheel and bring it in low position;
-r emove the steering wheel upper casing;
- disconnect the anti starting bushing connector from the front wiring;
-r emove the bushing;
- mount the new bushing outside the starting contact (anti theft) system;
- connect the bushing connector to the front wiring;
- mount the steering wheel casing;
- check the operation of the indicator and the anti starting system when the contact is off,
then with the contact on and the engine started. ANTI STARTING BUSHING REPLACEMENT

The RF remote control has no influence on anti starting system. It has only the function of
blocking/ unlocking the doors. The RF remote control with evolutionary code can use only two
keys as the decoder may manage only two different evolutionary codes. The key heads have an identification number formed by 8 alphanumeric characters (letters
and figures) , beginning with letter E.
In case of loosing one key, a key head and a metal insert ion will be ordered, then the
resynchronisation procedure of the RF remote control of t he ke y with t he decoder from the
vehicle must be performed. If the vehicle is provided with RF remote control key and this one
has been replaced, then perform the “ Simple synchronised procedure “. When the vehicle has
both keys with RF remote control, then perform the “Specific synchronised procedure “ after the
replacement of the second key.
NOTE - In the case only one ke y head is replaced, usually there is no need for
r esynchronisation of the other RF remote control.
- If both RF remote controls are desynchronised, one procedure of resynchronisation
will be performed with each remote control: perform the “Simple synchronisation
procedure for the first RF remote control” and the “Specific synchronisation procedure”
for the second RF remote control. Check then t he operation of blocking/ unlocking of the doors with both RF remote
controls. RF REMOTE CONTROL FOR BLOCKING/ UNLOCLING

If further to t he diagnostic, it is necessary the replacement of t he E.C.U. injection, for its
dismountin g, proceed as follows:
- disconnect the battery (the contact being off);
- dismount the screw from the battery attachment clip;
-r emove the battery;
- disconnect the injection computer from the engine wiring;
- dismount the two attachment nuts of the injection computer.
For mounting, perform in the reverse order the dismounting operations.
The i njection c omputer is delivered not coded. It i s necessary the memorising of a n anti
starting code in the computer, after this has been mounted was mounted.
Proceed as follows:
1. Set the contact on, without starting the engine, for a few seconds.
2. Take off the contact; after 10 seconds, the anti starting function is activated, and the anti
starting indicator will blink rarely ( one blink per second).
3. Set the contact on. The anti starting indicator must turn off and the engine can be started.
In order to disconnect the injection computer (E.C.U. injection) act upon the blocking lever
(picture 9, position A) of the connector in the direction of the B arrow, then the connector will be
lifted in the direction of the C arrow. In case the vehicle is bl ocked on the road further to seri ous damages of t he a nti starting
system, the “ Procedure repairing code introduction” may be used, which allows the moving of
the vehicle to the nearest DACIA service center for complete repairing. In order to perform this
procedure it is necessary the CLIP tester and the specific repairing code of that vehicle. ELECTRIC CONTROL UNIT INJECTION REPLACEMENT

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
