DISMOUNTING  ONE KEY-HEAD
(WITHOUT REMOTE CONTROL).

Place the key-head on a table, the half with

the metal insertion being downwards.

By means of a little screwdriver, act in such

way so that screwdriver point is supported on
the lower part (D) of the key-head. This will
enable the upper part gliding vis a vis of the lower
part.

DISMOUNTING  ONE KEY-HEAD
(WITH REMOTE CONTROL)

By means of a little screwdriver, that is

inserte d in the slot (E), act by carefully
detaching from clips the two parts of the key-
head.

Diagnostic – General

This document is presenting the diagnostic generally valid for all computers, for anti-starting

function.

In order to perform the diagnostic of this system, it is then all-important to dispose of the

following elements:

- workshop manual of the corresponding vehicle
- electric diagram of the function, for the corresponding vehicle
- special tools specified in the column “Necessary Special tools”.

GENERAL METHOD OF DIAGNOSTIC

- CLIP tester setting on, in order to identify the system that is equipping the vehicle

(identification of the computer family, program number, V. diagnostic..).

- Analysis of the “diagnostic” documents corresponding to the identified system.
- Acknowledgement of the information supplied in chapters “General”.

Reading of the memorised failure in the computer memory and taking advantage of the chapter
“Failures interpretation”.

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 is interpreted in the moment when it is declared “memorised”, the diagnostic

application conditions are present in “Recommendations”. If the conditions are not fulfilled, you
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 (accentuation 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 INTERVENTION

- CLIP diagnostic tester
- ELE 1622 electric multi-socket
- All-purpose mete

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.

SPECIAL SITUATIONS

Injection computer does not have any reference code in memory: the code sent by UCH is

written in the memory.

If there is no matching of the key codes / Cockpit Central Unit, the system is remaining

blocked and anti-starting LED is blinking (quick signal). The vehicle starting is not authorized.

ATTENTION: 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.

- Spare parts keys are delivered not coded,

so they have no code.

- It is possible in case of key’s loss, theft or

by client’s request, that one vehicle key is
decommissioned. This one may be re-assigned
on the same vehicle, if necessary.

ATTENTION:
〈〈〈〈 By this system, it is impossible the

replacement of C ockpit Central Unit and
keys in the same  time. These  parts are  sold
not coded.

〈〈〈〈The c ode  memorized by the system’s

e leme nts  can  not be er ase d (C oc kpit
Central Unit and injection computer). The
memorized code can not be erased.

GENERAL

Cockpit Central Unit (UCH) is replacing

the UCE decoder.

Cockpit Central Unit is located under

dashboard, left side.

IMPORTANT

When replacing the Cockpit central Unit

it will be necessary to set the function
corresponding to the vehicle equipment level,
by means of the CLIP tester.

ATTENTION

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
setting 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-frequency signal receiver is

integrated in Cockpit Central Unit

- Doors central locking button is not

activated when doors have been closed 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
