DESCRIPTION OF THE SYSTEM
By means of this system, the anti-starting is
activated few seconds after the contact has been
taken off (signalized by the blinking of the anti-
starting red indicator).
Its components are :
〈 key-head, equipped with a coded
electronic circuit (A).
OBSERVATION : the anti-starting
electronic is integrated in the remote control
printed circuit.
〈 anti-starting bushing (B), placed around the
ignition-start ing contact, equipped with an
electronic circuit having the purpose of key code
transmitting to the Cockpit Central Unit (UCH).

Cockpit Central Unit
For anti-star ting function , the Cockpit Central Unit is ensuring the following functions:
- key signal decoding
- dialoguing with the injection computer.
- Conducting the anti-starting indicator placed on instrument panel.
- Dialoguin g with the diagnostic tester.
Cockpit Central Unit (C) is placed on the driving post left part, being attached on the dashboard
lateral side, in a protection box.
For dismounting please see Chapter 87.
Anti-starting indicator, placed on instrument panel, it is used to signal:
- anti-starting system activatio n
- key non-recognition
-a system failure

Diagnostic – General
This document is presenting the diagnostic generally valid for all computers, for anti-starting
function.
In order to perform the diagnostic of t his system, it is then all-i mportant t o dispose of the
following elements: -workshop manual of the corresponding vehicle
- electric diagram of the function, for the correspondin g vehicle
- special tools specified in the column “Necessar y Special tools”.
GENERAL ME THOD OF DIAGNOSTIC
- CLIP tester setting on, in order t o identify the system that is e quipping the vehicle
(identification of the computer family , program number, V. diagnostic..).
- Analysis of the “diagnostic” documents corresponding to the identified system.
- Acknowledgemen t of the information supplied in chapters “General”.
Reading of the memorised failure in the computer memory and taking advantage of the chapter
“Failures interpretatio n”.
Attention : each failure is interpreted for a specific type of memorisation : present failure,
memorised failure, present or memorised failure). The specified checking for handling each
failure are not to be applied on the vehicle unless the declared failure is interpreted in the document
for its specific memorising type. The memorising type must be taken into consideration when the
tester is set on, after setting off and on of the contact. If a failure i s interpreted in t he moment when i t is declare d “memorised”, t he diagnostic
applicatio n conditions are present in “Recommendations”. If the conditions are not fulfilled, yo u
must take the ideas from the diagnostic of damaged element circuit checking, because the failure
is not anymore present on the vehicle. Apply the same method when a failure is declared as been
memorised by the diagnostic tester, but it is interpreted in the documentation only as “present”
failure state.
-Performing the conformity checking (accentuatio n of the possible failures, non-declared
yet by the system self-diagnostic) and application of the adequate diagnostic according to the
results. - Reparation validation (elimination of “client’s effect”)
- Diagnostic exploitation by “Client’s effect” if the problem still on.
NECESSARY SPECIAL TOOLS FOR INTERVENT ION
-CLIP diagnostic tester
- ELE 1622 electric multi-socket

OPERATION
When anti-starting system is on, the red LED is blinking (rare signal: one blink/sec).
After setting the contact on, the key code is transmitted to the Cockpit Central Unit.
If the code is recognized by the Cockpit Central Unit, this one is sending coded signals to the
injection computer and the anti-starting LED is off.
If signals issued by the Cockpit Central Unit and by the injection computer are matching, the
Cockpit Central Unit is authorizing the engine starting and the injection is unlocked.
SPECI AL SI TUATIONS
Injection computer does not have any reference code in m emory: the code sent by UCH is
written in the memory .
If there is no matching of the key c odes / Cockpit Central Unit, t he system is remaining
blocked and anti-star ting LED is blinking (quick signal). The vehicle starting is not authorized.
AT TE NT ION: when the battery is low charged, the voltage drop further to starter
action may reactivate the anti-starting. If voltage is too low, starting is impossible.

Diagnostic – General
-If doors are unlocked and none of them is
not opened in the next 30 seconds, the system
is automatically re-locking the vehicle doors
(without hazard lights blinking). -Cockpit central Unit is controlling the
vehicle inside lightening. In case a ceiling lamp
still lighted, Cockpit Central Unit is cutting the
supplying after approximately 30 minutes.
- The model “Full equipment” is controlling
the ceiling lamp progressive turning off, after
doors blocking by means of the remote control.
- Cockpit Central Unit may set on the hazard
lights in case of “shock connection” information
coming from UCE airbag.
-S pare parts keys are delivered not coded,
so they have no code.
-I t is possible in case of key’s l oss, theft or
by client’s request, that one vehicle ke y is
decommissioned. This one may be re-assigned
on the same vehicle, if necessary.
ATT E NT ION:

replacem ent of Coc kpit Central Unit and
keys in the same time. These parts are sold
not coded. 〈〈〈〈
The code me morized by the system’s
elements can not be erased (Cockpit
Central Unit and injection computer). The
memorized code can not be erased.
GENERAL
Cockpit Central Unit (UCH) is replacing
the UCE decoder.
Cockpit Ce ntral Unit is located under
dashboard, left side.
I MPORTANT
When replacing the Cockpit central Unit
it will be necessary to set the function
correspon ding to the vehicle equipment level,
by means of the CLIP tester.
ATT E NT ION
Starting is impossible unless the anti-
starting programming procedure is
performed.
When replacing a Cockpit Central Unit, it
is necessary to perform the programming and
settin g corresponding to the vehicle equipment
level.
When adding a key it is necessary that keys
re-assignation procedure be performed.
System’s characteristics.
- This system may work with maximum 4
remote controls (Cockpit central unit can
manage only 4 different codes).
-Radio-fr equenc y si gnal receive r i s

-D oors central locking button is not
activated when doors ha ve be en c losed by
means of the remote control.
-Doors locking and unlocking using the
remote control may be visualized by hazard
lights signals (if all doors are properly closed);
- locking : 2 signals
- unlocking: 1 signal

REPLACEMENT AND SETTING
Ne w parts are not coded. Once mounted on vehicle, in order to become under operation,
the memorization of a code it is necessary.
In order to perform this procedure, i t is absolutely necessary that some ve hicle parts are
already coded (with the vehicle code).
Refer to the assignations table:
ATTENTION :if a part is memorizing the code this one is assigned to this specif ic vehicle
and it is impossible that subsequently this c ode is erased or a second code is memorized. The
first time memorized code can not be anymore erased.
ASSIGNATION TAB LE
