This type of anti starting syste m is based on the key recognition, which has a special construction.
It may be separated in two elements which can be identified in the following way (pict.1): the key
he ad (pos.A.) made of plastic, which can be dismounted and the metal insertion (pos.B.), which is
fixed an d ensured by clipping in the key head.
In the key head, there is a coded independent electronic circuit, which is functioning without
battery. When setting the contact on, the anti starting bushing, placed around the starting contact,
is enquiring and catching the coded signal emitted by the key head, then sends it to the Electronic
Control Unit (E.C.U.) decoder. This one is attached on the front left pillar, under the lower casing
of the dashboard and has the function of receiving the code sent from the bushing. If the decoder
recognises the key code then it will send a coded signal to the injection computer, which compares
it with the previous memorised code and will authorise or not the start of the engine.
We mention that the system with radio frequency remote control (RF) of the doors blocking
/unlocking, has no influence to the anti starting system. In this case, the key head has a different
construction, having an activation button of the remote control and a red LED, which is lighted in
the moment of blocking/unlocking the doors, by pushing the key button. Inside the key head
there is the coded electronic circuit for the anti starting system and an imprinted electronic circuit,
s upplied by a battery, for t he RF remote control operation of blocking/unlocking the ve hicle
doors.
The anti starting system is activated after approximate 10 seconds from the breaking of the
contact and is visualised by the blinking of the anti starting indicator placed on the instrument
panel.
If the battery is low charged, the t ension drop on the starter, at starting,
may cause the activation of the anti starting system and the start of the engine is
impossible.

AT TENT ION
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 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 invoice.
If the replacement of t he battery from 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 ;
- with a little screwdriver, positioned as in the picture (picture2), act upon the key head in
the direction indicated by the arrow, in order to begin the dismounting.
-move carefully the upper side of the key in the direction indicated by the arrow (picture 3)
and then the two parts of the key will separate.
If the replacement of the metal insertion ( the mechanical part) of the key is needed, proceed as follows:
- open the key head according to t he a.m. procedure ;
- unlock carefully the maintaining claw (picture 4, pos.C) of the metal insertion (B).
-r emove the metal insertion by sliding from the key head.
Introduce by sliding t he new metal i nsertion until a « click » is heard, which confirm s its
attachment on the key head.

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.

When the contact is off and the anti starting system is activated, without any existing
failure,
the anti 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 after setting the contact on, the a nti start ing system doesn’t work properly, then the anti
starting indicator will blink rapidly (2 blinks per second). GENERALITIES

Af
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
