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
- key programming

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.

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.
Key recognition in normal operation
