The RF remote control has no influence on anti starting system. It has only the function of

blocking/ unlocking the doors. The RF remote control with evolutionary  code can use only two
keys as the decoder may manage only two different evolutionary codes.

The key heads have an identification number formed by 8 alphanumeric characters  (letters

and figures), 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 decoder from the
vehicle must  be  performed. If  the vehicle is  provided with RF remote control  key  and  this  one
has been replaced, then perform the “ Simple synchronised procedure “. When the vehicle has
both keys with RF remote control, then perform the “Specific synchronised procedure “ after the
replacement of the second key.

NOTE

- In the case only one key head is replaced, usually there is no need for

resynchronisation of the other RF remote control.

- If both RF remote controls are desynchronised, one procedure of resynchronisation

will be performed with each remote control: perform the  “Simple synchronisation
procedure for the first RF remote control” and the “Specific synchronisation procedure”
for the second RF remote control.

Check then the operation of blocking/ unlocking of the doors with both RF remote

controls.

If further to the diagnostic, it is necessary the replacement of the E.C.U. injection, for its

dismounting, proceed as follows:

- disconnect the battery (the contact being off);
- dismount the screw from the battery attachment clip;
- remove the battery;
- disconnect the injection computer from the engine wiring;
- dismount the two attachment nuts of the injection computer.

For mounting, perform in the reverse order the dismounting operations.
The injection computer is delivered not coded. It is necessary the memorising of an anti

starting code in the computer, after this has been mounted was mounted.

Proceed as follows:

1. Set the contact on, without starting the engine, for a few seconds.
2. Take 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 and the engine can be started.

In order to disconnect the injection computer (E.C.U. injection) act upon the blocking lever

(picture 9, position 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 case the vehicle is blocked on the road further to serious damages of the anti starting

system, the “ Procedure repairing code introduction” may be used, which allows the moving of
the vehicle to the nearest DACIA service center for complete repairing. In order to perform this
procedure it is necessary the CLIP tester and the specific repairing code of that vehicle.

A. ECU DECODER REPLACEMENT PROCEDURE AND ANTI STARTING

CODE MEMORISING

The new E.C.U. decoder is always not coded. After its mounting on the vehicle it is necessary

that this one is memorising the anti starting code in order to be operational.

NOTE
If only the E.C.U. decoder is replaced, there is no need of an intervention to the

E.C.U. injection (injection computer), which will keep the old anti starting code.

ATTENTION
After the E.C.U. decoder memorised the anti starting code, this code cannot be erased

or replaced with another one.

In order to perform this procedure, one of the keys of the vehicle and the CLIP tester are

needed. Perform as follows:

1. Connect the CLIP tester to the diagnostic socket and to the battery (or the lighter

socket) of the vehicle.

2. Read the configuration of the old E.C.U. decoder in the following way, before dismounting

it from the vehicle:

- select the type “SUPERNOVA” and the “050” equipping level;
- enter the menu “ COMPUTER TEST” then choose “ ANTI STARTING”
- access “COMMAND MODE” then “CONFIGURATIONS READING”
- note the configurations found : petrol/diesel, programming with 1 or 2 keys, ceiling delay,

the type of the doors’ blocking switch (CPE), etc.;

3. Get back to the menu “TEST COMPUTERS”
4. Remove the old E.C.U. decoder and replace it with a new one, the contact being off.
5. Enter the menu “ANTI STARTING”, then select “ STATE LIST”. If the E.C.U. decoder

is new, you must find the following states:
18G FIRST CYCLE MEMORISING………………........................ ACTIVE
19G NOT PERFORMED KEY PROGRAMMING……………….. ACTIVE
19D UNLOCKED KEY PROGRAMMING………………............. ACTIVE

OBSERVATION
If the states 19G and 19D are not “ACTIVE” this means the E.C.U. decoder has

been already used, so it isn’t new and cannot memorise another anti starting code.

Access the menu “COMMAND MODE” and then “CONFIGURATION”, where you will

configure the new E.C.U. decoder in the same way as the old one: petrol, 1 key, ceiling delay,
impulsion doors blocking switch, etc. selecting one by one these configurations, which you’ll
validate with “CLICK” on the blue button on right top of the screen.

7. Get back to  “ TEST COMPUTERS”
8. Set the contact on for 2 seconds in “M” position, without starting the engine. The anti

starting indicator will begin to  blink rapidly.

9. Access the menu “ STATE LIST”, where the following states must exist:

9D RECEIVED KEY CODE…………………………………………ACTIVE
19G NOT PERFORMED KEY PROGRAMMING…………………PASSIVE

10. Take the contact off. In the menu “COMMAND MODE” select “ACTUATORS”, then

validate “ FINISHED CALIBRATION” launching the command on the blue rectangle situated
on the right top of the screen. The message “COMMAND IN PROGRESS” will appear, followed
by “ FINISHED COMMAND”.

11. The anti starting indicator will blink rarely.

12. Get back to the  “STATE LIST”,  which now, must be like that:

18G  FIRST CYCLE MEMORISING ………………………………ACTIVE
19G NOT PERFORMED KEY PROGRAMMING...………………PASSIVE
19D UNLOCKED KEY PROGRAMMING………………………. PASSIVE

13. Set the contact in “M” position for 2-3 seconds in order to send the code to the E.C.U.

injection. The anti starting indicator must light for 3  seconds, then turn off.

14. Take off the contact. After 10 seconds, the anti starting indicator will blink rarely.
15. Check the engine starting with both keys, and then take the contact  off.
16. Check in the menu “ STATE LIST ”  if the state 10G “ANTI STARTING” is “ACTIVE”.

Perform the synchronisation of the TRF remote control with the decoder  (with 1 or 22 keys).

OBSERVATION
With the CLIP tester, a starting interdiction may be simulated, proceeding as follows:

- take the contact off; wait for 10 seconds, then the anti starting indicator will

blink;

- in the menu “COMMAND MODE” access “ ACTUATORS” then validate “

FORCED PROTECTION MODE” launching the command from the blue button
situated on the right topside of the screen. “COMMAND IN PROGRESS” will be
displayed and then “FINISHED COMMAND”.

- in the menu “STATE LIST” search for the state 10G ”ANTI STARTING”,

which  must be “ ACTIVE”;

- set the contact on “M” position; the anti starting indicator will blink rapidly,

and the engine starting is impossible;

- remove the key from the contact and check then the engine starting with both

keys, so the procedure is finished.
