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 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

NOTE
For the RF remote control synchronisation, after the replacement of an E.C.U.
decoder, the synchronisation procedure must be performed taking into account the
following situations: -for one RF re m ot e c ont ro l , pe rf orm t he “ SIMP L E SY NC H RONIS ED
PRO CEDURE”;
-f or the second RF remote control perform the “SPECIFIC SYNCHRONISED
PRO CEDURE”.
B. KIT REPLACEMENT PROCEDURE(E.C.U. decoder plus 2 key he ads)
In case of one kit replacement perform the following steps:
- memorising the anti starting code by the E.C.U. decoder
- memorising of the new anti starting code by the injection computer; i t is necessary the
repairing code (found out based on the old ke y heads code) and t he CLIP tester.
Perform the actions in the following sequence:
1. Mount the metal insertions of the old keys to the new key heads.
2. Send to Tech Line the key heads code, written on the vehicle invoice, in order to get the
repairing code. 3. Connect the CLIP tester to the diagnostic socket and to the battery (or t o the lighter
socket) of the vehicle. Read the configuration of the old E.C.U. decoder before dismounting off
the vehicle, as follows: - select vehicle type “SUPERNOVA” and the “050” equipping level;
- enter the menu “ COMPUTER TEST” then choose “ ANTI STARTING”;
- access “COMMAND MODE” then “READ CONFIGURATIONS”;
- note the configurations : petrol/diesel, programming with 1 or 2 keys, ceiling delay, the
type of the doors’ blocking switch (CPE), etc.;
4. Get back to the m enu “ANTI STARTING”;
5. Dismount the old E.C.U. decoder and replace it with a new one, the contact being off.
6. Check the configuration of the new E.C.U. decoder selecting “ STATE LIST”; here you
must find the following states: 18G FIRST CYCLE MEMORISINGPASSIVE…………………INACTIVE
19G NOT PERFORMED KEY PROGRAMMING ……………….ACTIVE
19D UNLOCKED KEY PROGRAMMING ………………………ACTIVE
NOTE
If the state 19G and 19D are not “ACTIVE” this m eans the E.C.U. decoder isn’t a
n ew one and cannot memorise another anti starting c ode. PROCEDURES

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
