ATTENTION !
In case of acid splashes on body, abundantly wash with water all affected parts.
If eyes have been touched, urgently call for a doctor.
1. DANGER = EXPLOSION RISK
During battery charging, connected to a charger-rectifier, oxygen and hydrogen emissions are
occurring. These gases emission is stronger when the battery has reached the complete charge
condition and the produced gas quantity is in direct connection with the charging current.
The oxygen and hydrogen are associating in the free spaces, at the plates surface, forming a
detonate mixture, which is very explosive. The littlest spark is sufficient to generate an explosion,
followed by the battery case brooking and a cid splashing in the proximate environment. The
persons, who are a round, are in da nger t o be hurt by t he e xploded case chips or by the acid,
which may come i n contact with the eyes, hands, or face.
ATTENTION !
Strictly observe the following recommendations:
- before connecting or reconnecting a battery, ensure that all consumers are shouted off.
- during battery charging in a room, using a charger-rectifier, turn it off before connecting or
reconnecting the battery to this one;
- do not place metallic objects on t he ba ttery for not producing a short-c ircuit between i ts
pl ugs ;
- never bring closer to a battery, a n open flame, a welding lamp or another fire source.
THE ELECTRIC EQUIPMENT PROTECTION
In case of an intervention on the vehicle, some measures must be taken, for the electric equip-
ment protection against damages or for avoiding a short-circuit that may lead to vehicle firing.
The battery is to be allwith disconnected by first disconnecting the negative plug and then t he
positive one. Connection is to be done by performing the disconnecting operations in the reverse
order.
Before starter acting, check if the battery is correctly connected (the negative plug connected
to the mass), and if the plugs are clean and well tightened. Never disconnect the battery when the
engine is running, in order not to damage the voltage regulator, the alternator or some components
of the vehicle checking electronic systems. The alternator, voltage regulator disconnecting, and
the interventions at their connections, are to be performed only when the engine is stopped (the
alternator is not turning) and the contact is taken off. In case the battery is connected to a charger-rectifier, for charging (without dismounting the
battery off the vehicle), it is obligatory to disconnect the wiring from the battery plugs.

ACCOUSTIC WARNING - ANTI STARTING
82 - 1
This type of anti starting system is based on the key recognition, which has a special constructio n.
It may be separated in two elements which can be identified in the following way: the key head
(position A.) made of plastic, which c an 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 ra dio 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 L ED, which i s lighted i n the moment of bl ocking/unlocking the doors, by
pushing the key button. Inside t he ke y head there i s the coded electroni c c ircuit 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.
AT T E N T I O N !
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 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

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.

Procedures
17. The procedure is finished. Check the engine starting with both keys.
REMARK:
For the RF remote control synchronisation, after the replacement of a kit, take into account
the following situations:
- for the first RF remote control, perform the “ SIMPLE SYNCHRONISED PROCEDURE”;
- for t he second RF re m ote control pe rform the “SPE CIFIC SYNCHRONISE D
PROCEDURE”. C. CODE REPAIRING INTRODUCTION PROCEDURE
The repairing code may be introduced only by means of the CLIP tester. This is possible only
if when setting the contact on, the anti starting indicator blinks rapidly, this being confirmed by the
state:
10G ANTI STARTING ……………………………………………….ACTIVE
After getting from DACIA database the repairing code (based on the vehicle chassis series
and on the code from the vehicle’s key head), perform the following operations.
1. Connect the CLIP tester to the diagnostic socket and to the battery (or to the lighter
socket) of the vehicle.
2. The anti start up indicator must blink slowly , the contact being taken off.
3. Set the contact in “M” position. The indicator must blink rapidly.
4. Select vehicle type “B41”;
5. Select the menu “ COMPUTER TEST” then select “ ANTI STARTING”.
6. In the menu “STAT E LIST” find the state 10G “ANTI STARTING” which must be
“ACTIVE”. 7. Access “COMMAND MODE” then select “ACTUATORS”.
8. Select the command “ MANUAL CODE INTRODUCTION” where you will write the
repairi ng c ode (form ed of 4 fi gures), then validate it with t he ke y “ ENTER”. The message
“COMMAND IN PROGRESS” will be displayed followed by the message “FINISHED
COMMAND”. 9. Now the procedure is finished and you may start the vehicle engine.
AT T E N T I ON!
Yo u may perform three attempts of introducing the repairing code; if after the third
essay the code is not yet valid, wait for 15 minutes, take off the contact and then set it
again, then other three attempts may be performed.
REMARK:
This procedure does not decode the injection computer, but is only allowing the start
of the vehicle’s engine. After 10 minutes have passed from the first introduction of the
r epairing code or after the disconnection of the battery, the vehicle’s engine cannot be
s tarted unless a new repairing code is introduced.
