If the states
remain unchanged, check the following:
- electric connections of the decoding bushing
- the electric connections between the E.C.U. decoder and the decoding bushing
- the tension of the battery must have more than 8V when the starter is activated.
If all these are conformable, proceed to the replacement of the decoding bushing, and then
check again the a .m. states.
II. SOLVING MODE
When an electric ke y head (or both) is damaged, order (Info TECH LINE 0248/213766) a
new set of two electronic heads, subject to the vehicle type, as follows: TRF key head set – item no. 6001 543 684, 1 set, for DSN equipped with
anti intrusion (CLIMA or RAPSODIE)
TR-TRF key head set – item no. 6001 544 452, 1 set, for DSN without anti
intrusion (CLIMA or RAPSODIE)
TR key head set – item no. 6001 543 683, 1 set, for DSN EUROPA
Send to Tech Line (0248 213766), the chassis series no, the anti starting code of the damaged
key heads, the a nti starting code of the ne w key heads, and they will sent at their turn, to the
service center, the repairing code (taking into account that this code has a special regime). Additionally , there are necessary the new key heads, the E.C.U. decoder (obligatory TRF, if
the vehicle is equipped with central locking), the repairing code of the computer; proceed then to
the replacemen t of these items performing the following operation:
A) Replacement- c hecking electronic key heads :
Replace t he damaged key heads with the new ones (the metal insertions remain the same),
then by means of the CLIP tester, selecting COMPUTER TEST- ANTI STARTING- STATE
LIST, check following states with both keys:
If the states are in the following configuration, when setting the contact on, consecutively with
both keys:
ANTI STARTING……………………………………………..........ACTIVE
RECEIVED KEY CODE………………………………………….. ACTIVE
ACCEPTED KEY CODE…………………………………………PASSIVE DIAGNOSTIC

then the new electronic key heads are functioning and pass to the next step. If the states are as
follows,
with one of the key, then both keys must be again replaced:
ANT I ST AR TING…………………………………………………..ACTIVE
RECEIVED KEY CODE………………………………………… PASSIVE
A CCEPTED KEY CODE…………………………………………PASSIVE
B) Replacement – checking of the E.C.U. decoder:
Pr oceed at the replacement of the vehicle E.C.U. decoder with the new one, then check by
means of the CLIP tester (with the contact taken off), selecting COMPUTER TEST- ANTI
STARTING- STATE LIST, the following states:
FI RST CYCLE MEMORISING………………………………….. PASSIVE
NOT PERFORMED KEY PROGRAMMING…………………….. ACTIVE
UNL OCKED KEY PROGRAMMING………………………..…...ACTIVE
If one of the states NOT PERFORMED KEY PROGRAMMING or UNLOCKED
KEY PROGRAMMING is not ACTIVE , then the E.C.U. decoder was used before and
must be replaced.
C) E.C.U. decoder coding:
Further on, perform the following operations:
- with the contact taken off, in COMPUTER TEST- ANTI STARTING- STATE LIST,
launch the command FINISHED CALIBRATION. - set t he contact on for a few seconds, the anti starting LED indicator blinks rapidly;
- take the contact off and va lidate t he c ommand FINISHED CALIBRATION (by the
blue button from the right side of the screen), in this moment the E.C.U. decoder is coded.
- check in the STATE LIST the following states which obligatory must be:
FIRS CYCLE MEMORISING…………………………………...... ACTIVE
NOT PERFORMED KEY PROGRAMMING…………………… PASSIVE
UNL OCKED KEY PROGRAMMING……………………………PASSIVE DIAGNOSTIC

D)
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

DIAGNOSTIC – FAILURES AND STATES INTERPRETATION
1. FAILURE OF COMUNICATION CLIP TESTER/ E.C.U. DECODER
RECOMMENDATION Check if the lines K and L are not disturbed by another computer of the vehicle.
Check the fuse state F15 (vehicles up to 01.06.2001) or F07 (vehicles after 01.06.2001).
Replace the fuse if necessary.
Check if the CLIP tester is not the cause of the failure; check if the tester communicates with
another computer of the same vehicle (injection computer).
M easure the tension of the vehicle’s battery (U> 10,5V). If necessary, charge the battery.
Check if the E.C.U. decoder is well connected to the vehicle’s wiring.
Check the right supply of the E.C.U. decoder: - presence of t he ground at pin A8 of the E .C.U. decoder
- supply + I.C. at pin A9 of t he E .C.U. decoder
Be sure that the diagnostic socket i s proper supplied, according to the circuit diagram.
Check the continuity and the isolation of the electric wiring on the corresponding pins layout.

7. 11 STATE: OPERATE THE RF REMOTE CONTROL / GOOD RF SIGNAL
INDICATION
Do not access the following diagnostic
unless the state 11D
RECOMMENDATION becomes ACTIVE when operating the RF remote control. Check if the keys belong to the vehicle in question.
There is a desynchronising between the code of the RF remote control and the E.C.U. decoder
if at the activation of the remote control, the 111D state remains PASSIVE and the state 11G
becomes AC TIVE for 3 seconds, then becomes PASSIVE. The blocking / unlocking of the
