ACCOUSTIC WARNING - ANTI STARTING

82 - 1

This type of anti starting  system 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: the key head
(position A.) made of plastic, which can be dismounted and the  metal insertion (position B),
which is fixed and 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 engine starting

In case of the system with radio frequency remote control (RF) of the doors blocking /

unlocking, 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 a printed electronic circuit, supplied by a battery, for the RF remote control
operation of blocking/unlocking the vehicle 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.

ATTENTION !
If the battery is low charged, the tension drop on the starter, at starting, may cause

the activation of the anti starting system and the engine starting is impossible.

THE KEY HEADS

The key head has marked inside, a number of identification, formed by 8 alphanumeric

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 replacement 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;
- unlock carefully the maintaining claw (A) of the metal insertion (B);
- remove the metal insertion, by sliding, from the key head;
- introduce by sliding the new metal insertion until a  « click » is heard, confirming its attachment

on the key head;

- close the 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 :
- decoding the signal received from the anti starting

bushing;

- sending a code to the injection computer in order to

authorise the engine starting;

- controlling the anti starting indicator of the instrument

panel;
receiving the coded signal from the anti starting bearings,
for the vehicles equipped with RF remote control;

REMARK :
In case both keys were lost, the code of the key head (8 characters) and the code of the

metal 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 series of that
vehicle, accessing the  database of the  DACIA manufacturer, calling the  “Client Voice”
department (phone 0248 500 000).

E.C.U.  DECODER

General

- commanding the blocking/unlocking of the doors, if the vehicle is provided with RF remote

control keys;

- commanding the ceiling delayed light, for vehicles equipped with this system.

The  anti starting bushing is located around the starting contact and is accessible after the

dismounting 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 vehicles 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 remote control.

The recognition of the two types of decoding bushings is performed by means of codes labelled

on their body, as follows :

- code 042264J               - for vehicles without RF remote control;
- code 8200044257          - for vehicles with RF remote control.

    REMARK :
      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 ty pe of
decoder.
     The identification of the  two types of E.C.U. decoder is realised by the  inscriptions on the
labels as follows:

- code P8200032783H and the inscription TRANS-PLAF for the  vehicle s without RF

remote control;

- code P8200032776H and the inscription TRF-TRANS-CAR for the  vehicles with RF

remote control.

ANTI STARTING INDICATOR

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

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 anti starting system doesn’t work properly, then the anti

starting indicator will blink rapidly (two blinks per second).

The ceiling delayed lighting is activated subject to the position of the light glass (1):
- position A   the ceiling is lighting permanently;
- position B  delayed 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
moment of setting the contact;

- position C   ceiling light off.
