TEPS IN DIAGNOSING
INSPECTION OF DEFECTS
This stage is the indispensable start ing-point before any intervention on the car. if the
defect is indicated by the t ester, then remedy it; if no defe ct ha s been signalled by t he
tester, a conformity inspection will ha ve to be made, thus helping t o spot the possible
causes. To do that check on the fol lowing elements:
- the electric circuit corre sponding to the defect which has been signalled;
- the electric connectors along the circuit (oxidized spots, deform ed plugs, etc.);
- the e lectric re sistance that is not i n keeping with the element connected to that
electric circ uit; - the state of the plugs (cut or worn-out insulation, areas with traces of pressing, etc.).
CONFORMITY I NSPECTION
Its aim is to check on the various states and parameters, to detect some anomaly when
the tester failed to find defe cts.
This phase allows:- to diagnose a breakdown or failure without displaying the defe ct corre sponding to
a deficient functioning of the parts or following complaints from the user. - to check the good functioning of the injection system and to ensure no breakdown
or failure will appear immediately aft er the repair ha s been made.
So, this heading concerns a diagnosing of the various states and parameters, unde r
certain inspection conditions.
If a state is defective or a parameter is be yond tolerance, the corre sponding diagnose
page will have to be consulted.
LOCALIZING A DEFECT AFTER USER’S COMPLAINT
If after the inspection of the injection system by means of the CLIP tester (inspection of
defects and i nspection of conform ity) the cause of the user’s c omplaint ha s not be en e limi-
nated, then the logical schema of finding out of the possible causes of the problem will be
used. These schemas will only be used under the following circumstances:- no defect has been shown by the tester;
- no anomaly has been signalled by the inspection of conformity;
- the car does not work properly. DIAGNOSING-INTRODUCTION

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

Memorising of the new code of the injection computer
- in ACTUATORS
launch the command MANUAL INTRODUCTION CODE ; type
the repairing code of the old key kit, then validate it with the key
ENTER.
- the message “COMMAND IN PROGRESS ” will be displayed followed by the message
“FINISHED COMMAND ”.
-s et the contact on; t he anti starting LED indicator will start blinking, then take off the
contact;
-set the c ontact on for 10 seconds ; take off the contact;
- check if the engine starts with the two keys.
If the engine doesn’t start, repeat this operation (point D).
E) Key resynchronisation (remote controls)
-if the vehicle is equipped with only one remote control, its resynchronisation will be
performed as follows (simple resynchronisation);
- with t he contact taken off, push continuously on the c entra l l ocking but ton from the
dashboard, up to the moment the anti starting LED indicator remains lighted (the doors actuators
are performing a closing/opening course.) From this moment, t he operator has 10 seconds to
perform the next operation; - push twice on the remote control (the doors actuators are performing a closing/opening
course.) and the anti starting LED indicator turns off; - if the vehicle is equipped with two remotes controls, perform the simple resynchronisatio n
procedure for the first key and a specific resynchronisation procedure for the second key, with
the CLIP tester as follows: - in COMPUTER TEST select ANTISTARTING with t he c ontact t aken off, then
COMMAND MODE , CONFIGURATION ; launch the command PROGRAMMING OF
THE SECOND TIR/TIE KEY and validate (the doors actuators are performing a closing/
opening course.). Then within 10 seconds, push twice on the remote control (the doors actuators
are performing a closing/o pening course).DIAGNOSTIC
