THE KEY HEADS
The key he ad ha s marked i nside, a num ber of identification, form ed by 8 a lphanumeric
characters (letters and figures) and this one is mentioned on the vehicle’s purchasing invoice.
In case the reading of the code marked in the key head is necessary, this can be opened in the
following way :
- keep the key in horizontal position, the half with the metal insertion being downwards ;
- using a little screwdriver, act upon the key head in the direction indicated by the arrows (A
and B), in order to begin the dismounting;
- move carefully the upper side of the key in the direction indicated by the arrow (C) and then
the two parts of the key will separate.
If the repla cement of the metal insertion (the mechanical part) of the key is needed, proceed as
follows : - open the key head according to the a.m. procedure;
- un lock carefully the maintaining claw ( A) of the metal insertion ( B);
- re mo ve the metal insertion, by sliding, from the key head;
- introduce by sliding the new metal insertion until a « click » is heard, confirming its a ttachment
on the ke y head;
- close th e two half of the key head.
ATTENTION !
After dismounting the key head, it is forbidden to touch the electric circuit located inside
of it, as this can cause the further non-operation of the anti starting system and impose a
replacement of the key head.

The E.C.U. decoder has the following functions :
- deco ding the signal received from the anti starting
bushing; - send ing a code to the injection computer in order to
author ise the engine starting;
- c ontrolling the anti starting indic ator of the instrument
panel;
receiv ing the coded signal from the anti starting bearings,
for the vehicles equipped with RF remote control;
REMA RK :
In case both keys were lost, the code of the key head (8 characters) and the code of the
me tal insertion (4 characters) can be red from the vehicle-purchasing invoice. If also the
invoice was lost, the two mentioned codes can be found out based on the chassis s eries of that
vehicl e, acces sing the database of the DA C IA manufacture r, callin g the “C lient Voice”
department (phone 0248 500 000).
E.C.U. DECODER
General
- commandi ng the blocking/unlocking of the doors, if the vehicle is provided with RF remote
c ontrol keys;
- co mma nding the ceiling delayed light, for vehicles equipped with this system.
Th
e an ti starting bushing is located around the starting contact and is accessible after the
d ismounting the steering wheel’s half-cases. It catches the signal from the key head and then sends
a coded signal to the E.C.U. decoder.
The ve hicles equipped with RF remote control keys for blocking/ unlocking the doors are provided
with another anti starting bushing which transmits to the E.C.U. decoder also the signal received
from the RF remo te control.
Th e recognition of the two types of decoding bushings is performed by means of codes labelled
on their body, as follows : - code 04 2264J - for vehicles without RF remote control;
- code 8200 044257 - for vehicles with RF remote control. ANTI S TARTING BUSHING

REMARK :
The vehic les equipped with this anti starti ng system, have a type of decoder, and those
provided also with R F remote control for l ocking/ unlocking doors have another ty pe of
decoder.
Th e identification of the two types of E.C.U. decoder is realised by the inscriptions on the
labels as follows: - code P8200032783H and the in scri ption TRANS-PLAF for the vehicle s w ithout RF
remote control; - code P8200032776H and the inscr iption TRF-TRANS-CAR for the vehicles with RF
remote control. ANTI STARTING INDI CATOR
It is located on the instrument panel (position A) and has the following functions:
- signalising the activation of the anti starting system;
- signalising the case of non identifying the key head;
- signalling 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.
When the contact is off and the anti starting system is activated, without any existing failure, the
an ti starting indicator must blink slowly (a blink per second).
After setting the contact on, the anti starting indicator must light for 3 seconds and then turn off.
If a fter setting the contact on, the anti starting system doesn’t work properly, then the anti
starting indicator will blink rapidly (two blinks per second). Th
e ceiling delayed lighting is activated subject to the position of the light glass ( 1):
- position A the ceiling is lighting permanently;
- position B de layed ceiling lighting; this will light for 15 seconds after driver’s front door closing
or after the command of unlocking the doors with the RF remote control. This delay turns out in the
mo ment of setting the contact;
- po sition C ceiling light off.

After ordering a new key head based on the alphanumeric code mentioned on the invoice,
dismount the old key head and remove the metal insertion (mechanical part), then introduce the old
meta l insertion in the new key head according to the previously mentioned procedure. In case the
key head is provided with RF remote control for blocking/ unlocking the doors, after its replacement,
pe rfor m the synchronising procedure of the RF remote control with the decoder, subject to the
fo llowing cases:
- a fter the replacement of the RF key, perform the “Specific synchronised procedure” in order
to bring into phase the RF remote control with the decoder. - if both keys are replaced, perform the “Simple synchronised procedure” for the first RF key
and the “Specific synchronised procedure” for the second one RF key.
If a key was lost, a new key head and a metal insertion are to be ordered.

All new decoders, are not coded. After mounting on the vehicle, it is necessary the memorisation
of the key head code by the decoder in 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
di ag nostic of the anti starting system, using the CLIP tester, the replacement of the decoder is
imposed, proceed as follows:
DISMOUNTIN G
- disconnect the (-) terminal of the battery;
- d ismount the ECU decoder-relays assembly;
- ro tate the ECU decoder assembly, in order to have access at its rear connectors;
- d isconnect the front wiring connector from the E.C.U. decoder;
- deta ch ECU decoder from clips of the relays-ECU decoder support.
REMOU NT I NG
- attach in clips the new E.C.U. decoder in the support, connect the front wiring connector to
the ECU decoder, then attach the assembly on the driving post cross member in its place and
mo unt its attachment screw;
- remo unt carefully the access flap of the fuse box;
- reconnect the (-) term inal of the battery.
Proceed then to the insertion of the anti starting code using the contact key, then to its me morising
(va lidation) in the E.C.U. decoder, using the CLIP tester. For this purpose, perform the “E.C.U.
decoder replacement procedure and anti starting code memorising”. Check then the correct operation
of the anti starting system with both keys.
ATTENTION!
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), then the “ Kit
replacement procedure” must be performed.

If, further to the diagnostic by means of the CLIP tester, it is established the necessity of the
rep lacement of the anti starting bushing, proceed as follows:
- d isconnect the (-) terminal of the battery;
- d ismount the attachment screws of the steering wheel half-casings ;
- detach from clips the steering wheel half-casings;
- remove the steering wheel half-casings;
- d isconnect the anti starting bushing connector from the front wiring;
- remove the bushing;
- mount the new bushing outside the starting contact (anti theft mechanism);
- co nnect the bushing connector to the front wiring;
- a ttach in clips the steering wheel half-casings and mount the attachment screws;
- check the operation of the indicator and the anti starting system when the contact is off, then
with the contact on and then with the engine started.

The RF remote control has only the function of blocking/ unlocking the doors. The RF remote
c ontrol with evolutionary code can use only two keys as the decoder may manage only two different
e volutionary codes.
Th e key heads have an identification number formed by eight alphanumeric characters (letters
and fi gures), beginning with letter E. In case of loosing one key, a key head and a metal insertion
will be ordered, then the resynchronisation procedure of the RF remote control of the key with the
de coder from the vehicle must be performed.
If the ve hicle is provided with RF remote control key and this one has been replaced, then
pe rfor m the “ Simple synchronised procedure “. When the vehicle has both keys with RF remote
contro l, then perform the “Specific synchronised procedure “ after the replacement of the second
key.
REMA RK:
If only one key head is replaced, usually there is no need for resynchronisation of the
other RF remote control.
If both RF re mote controls are desynchronised, one procedure of resynchronisation will
be performed w ith each remote control: perform the “Simple synchronisation procedure for
the first R F r emote control” and the “Specific synchronisation procedure” for the second
RF remote control.
Check then, the operation of doors blocking/ unlocking with both RF r emote controls.

If further to the diagnostic by means of the CLIP tester, it is necessary the replacement of the
E. C.U. (computer) injection, for its dismounting, proceed as follows:
-disconnect the battery (the contact being off);
-d ismount the screw from the battery attachment clip;
-remov e the battery;
-d ismount the two attachment nuts of the injection computer and of the ECU protector;
-remov e the injection ECU protector;
-d isconnect the injection computer from the engine wiring;
-d ismount the ECU injection
For mounting, perform the dismounting operations in the reverse order.
The in jection computer is delivered not coded. It is necessary the memorising of an anti starting
code in the computer, after this has been mounted.
Proceed as follows: 1. Set the contact on, without starting the engine, for 5 seconds.
2. Ta ke 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 after 3 seconds and the engine
can be started. In or der to disconnect the injection computer (E.C.U. injection) act upon the blocking lever (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 ca se the vehicle is blocked on the road further to serious damages of the anti starting system,
the “ Procedure for repairing code introduction” may be used, which allows the moving of the
vehicle to the nearest DACIA service centre for complete repairing. In order to perform this
procedur e it is necessary the CLIP tester and the specific repairing code of that vehicle.
