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.

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
LINE.

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.
