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 i s replaced, there i s no need of an i ntervention to t he
E.C.U. injection (injection computer), which will keep the old anti starting code.
AT TENT ION
After the E.C.U. de coder memorised the anti starting c ode, this code cannot be erased
or replaced with another one.
In order t o perform this procedure, one of the keys of t he ve hicle 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 t he 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/d iesel, programming with 1 or 2 keys, ceiling delay,
the type of the doors’ blocking switch (CPE), etc.;
3. Get back to the m enu “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
OBSERVAT ION
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 “CONFIGURA TION”, 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. PROCEDURES

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 i n order t o send the code to t he 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 START ING” is “ACTIVE”.
Pe rform the synchronisation of the TRF remote control with the decoder (with 1 or 22 keys).
OBSERVAT ION
With the CLIP tester, a starting interdiction may be simulated, proceeding as follows: -take the c ontact off; wait for 10 seconds, then the anti starting indicator will
blink; -in the m enu “COMMAND MODE” access “ ACTUATORS” then validate “
FORCED PROTECTION MODE” launching the command from the bl ue button
s ituated 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 “ ACT IVE”;
-set the contact on “M” position; the anti starting indicator will blink rapidly,

NOTE
For the RF remote control synchronisation, after the replacement of a kit, take into
account the fol lowing situations: - for the first RF remote control, perform the “ simple synchronised procedure”;
- for the second RF remote c ontrol perform the “specific synchronised procedure” .
C. CODE REPAIRING INTRODUCTION PROCEDURE
The repairing code may be introduced only by the 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 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 “SUPERNOVA” and “050” equipping level.
5. Select the menu “ COMPUTER TEST” then choose “ ANTI STARTING”.
6. In the menu “ STAT E L IST” find t he state 10G “ANTI STARTING” which m ust be
“ACTIVE”.
7. Access “COMMAND MODE” then select “ACTUATORS”.
8. Select the command “ MANUAL INTRODUCTION CODE” where you will write the
repairing code (formed of four figures), then validate it with the key “ENTER”. T he 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 TENT ION
You may perform three essays of introducing the repairing code; if aft er the third
essay the code is not yet valid, wait for 15 minutes, take off the contact and then put it
again, other t hree essays being allowed.
NOTE
This procedure does not decode the injection computer, but allows only the start of
the vehicle’s engine. After ten 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. PROCEDURES

D. SIMPLE S
YNCHRONISED PROCEDURE
This procedure allows the synchronisation of a RF remote control with E.C.U. decoder and
is to be applied in the following situations:
- the RF remote control c ode is no longer i n the range of the E.C.U. decoder re ception,
because of consecutive pushing over a 1000 time on the RF remote control button.;
- the replacement of the E.C.U. decoder with a new one;
- the replacement of the RF remote control if the E.C.U. decoder is new (E.C.U. decoder
replacement plus a RF key.)
The following operations will be performed: - take off t he contact
- push and maintain like that for about 5 seconds, the doors locking switch located on the
dashboard ; the doors actuators are performing a closing/opening course.
- during the next 10 seconds, confirmed by the permanent lightening of the anti starting
system indicator, push twice the RF remote control button; the doors actuators are performing a
closing/o pening course.
- the procedure of synchronisation is finished; check the blocking/ unlocking by pushing
the RF remote control.
OBSERVAT ION
Duri ng those 10 seconds you can visualise by means of the CLIP tester the state 17G
“THE PROGRAMMING IN PROGRESS OR THE TIR/TRF
RESYNCHRONISATION” which must be ACTIVE.
E. SPECIFIC SYNCHRONISED PROCEDURE
This procedure is used for the synchronisation of the second RF key with E .C.U. decoder
and will be performed as follows:
- connect the CLIP tester to the diagnostic socket and the battery (or the lighter socket) of
the vehicle. - select the vehicle type “SUPERNOVA” and the “050” equipping level;
- select the m enu “ COMPUTERS TEST” then “ ANTI STARTING”
- enter the m enu “COMMAND MODE” and select “CONFIGURATION”
- validate the command “ PROGRAMMI NG THE SECOND TIR / TRF KEY” launching
the command from the blue button situated on the right top of the screen; the doors actuators are
performing a closing/opening course.
- during the next 10 seconds, confirmed by the permanent lightening of the anti starting
system, push twice the RF remote control button; the doors will block and then unlock and the
anti starting indicator will t urn off. The second remote control is now synchronised. Check the
