IMMOBILISER
Coded key immobiliser system
GENERAL
The immobiliser is controlled by a key recognition
system (known as coded key immobiliser system).
An independently operating coded chip without a
battery is integrated into each head of the vehicle
keys.
When the ignition is switched on, an antenna ring
around the ignition switch interrogates and cap-
tures the code from the head of the key and trans-
mits it to the decoder unit.
If the decoder unit recognises the code, the vehi-
cle will be permitted to be started.
The immobiliser is activated a few seconds after
the key is withdrawn from the ignition and this is
shown by the flashing of the red immobiliser war-
ning light on the instrument panel.
If there is a fault in the key recognition system, a
security code may be entered using the XR25 only.
This code may be communicated to the repair
agent (on his request) by the local assistance net-
work (depending on country, for example: Delta
Assistance on 0800.05.15.15 for France, NVSR for
the UK by fax only).
IMPORTANT: The repair agent must inform the
customer that the immobiliser system will reset it-
self automatically 10 minutes after switching the
ignition off.
82
NOTES
This system may be fitted to petrol or diesel vehi-
cles.
Petrol vehicles: the immobiliser function is carried
out by the injection computer.
Diesel vehicles: the immobiliser function is carried
out by the coded solenoid valve (on the injection
pump).
If the vehicle is fitted with a remote control for
door locking, a single decoder unit carries out
both functions (immobiliser and remote control).
The remote control has no effect on the immobili-
ser system (see section 88).
On these vehicles, the identification number of
the key heads contains eight alphanumeric cha-
racters, beginning with the letter E or A.

• A decoder unit (D) in the dashboard on the left
hand side.
This has the following functions:
- decoding of the key signal from the antenna
ring,
- management of the engine immobiliser
system by the sending of a code to the injection
computer (petrol) or coded solenoid valve
(diesel) to authorise the vehicle to be started
- operation of the red immobiliser warning light,
- locking and unlocking of the opening elements
(depending on version),
- timed illumination of the courtesy light (vehicle
fitted with a door locking remote control).

ment panel used to :
- indicate activation of the engine immobiliser
system,
- signal a fault in the system for vehicles with a
coded solenoid valve (diesel) or non-
recognition of the key,
- signal entry into the door locking remote
control resynchronisation mode (depending
on equipment).
• An injection warning light (petrol vehicle)
which indicates a fault in the:
- injection,
- engine immobiliser system when the engine
is running (flashes during deceleration and
at idle speed).

IMMOBILISER
Coded key immobiliser system
OPERATION
When the immobiliser system is activated (ap-
proximately 10 seconds after cutting + after igni-
tion feed), the red immobiliser warning light
flashes (slow flashing; 1 flash / second).
After switching the ignition on, the antenna ring
analyses the code from the key and transmits it to
the decoder unit.
If the code is not recognised by the decoder unit,
the injection warning light (petrol) illuminates for
a few seconds and extinguishes while the red im-
mobiliser warning light flashes (rapid flashing).
If the code is recognised by the decoder unit, it
sends a code to the injection computer (petrol) or
coded solenoid valve (diesel) via the coded line
and extinguishes the red immobiliser warning
light (after approximately 3 seconds).
At this precise moment, one of several situations
may arise:
- The injection computer (petrol) or coded sole-
noid valve (diesel) has no reference code in its
memory :
• the code sent to it is stored in its memory.
82
- The injection computer (petrol) or the coded
solenoid valve (diesel) has a reference code in
its memory:
• the code sent to it is compared with the code
in its memory,
• if the two codes match, the computer un-
locks the injection system (petrol) or coded
solenoid valve (diesel) and the engine may
be started.
When the ignition is switched on, the injec-
tion warning light (petrol) and the immobili-
ser warning light illuminate for 3 seconds then
extinguish, showing that the system is opera-
ting correctly.
• if the two codes do not match, the system re-
mains locked to prevent the engine from
being started.
When the ignition is switched on, the injec-
tion warning light flashes (petrol) and the red
engine immobiliser warning light illuminates
permanently then extinguishes or the red im-
mobiliser warning light remains illuminated
permanently (diesel) indicating that the co-
ded solenoid valve has not recognised the
code.The vehicle may not be started.
NOTE : to ensure the system operates correctly, no
objects (eg. : keyrings) should be allowed to come
between the key and the antenna ring.
IMPORTANT: when the vehicle battery has a low
charge, the drop in voltage caused by operating
the starter may set the immobiliser. If the voltage
is too low, the engine cannot be started, even by
pushing the vehicle.

REPLACING A KEY HEAD
The coded chip in the key head or the remote
control (depending on equipment) is faulty :
- order a replacement key head using the num-
ber in the faulty key head (eight alphanumeric
characters beginning with the letter E or A). If
the key head is from a remote control type key,
carry out a resynchronisation operation.
IMPORTANT: The resynchronisation procedure
differs depending on if the decoder unit has
been replaced or not (see specific or simple re-
synchronisation procedure in section 88).
- if the customer requires the fault to be repaired
immediately (2nd key unavailable) a complete
kit may be fitted to the vehicle (decoder unit
plus two key heads) (see replacing a complete
kit).
The key has been lost:
- order a replacement key head using the num-
ber in the key head of the 2nd key (eight alpha-
numeric characters beginning with the letter E
or A) or on the label (normally attached to the
keys when the vehicle is delivered).
In this case, remember to order the metal
number insert for the new key head. If the key
head is from a remote control type key, carry
out a resynchronisation operation.
IMPORTANT: The resynchronisation procedure
differs depending on if the decoder unit has
been replaced or not (see specific or simple re-
synchronisation procedure in section 88).
IMPORTANT: Do not touch the key head chip
when taking note of the number in the key head.
Any key which has been touched must be repla-
ced.
NOTE: if the key head number cannot be located
(both keys lost together with the label), the
complete kit must be replaced (decoder unit, plus
2 transponder keys, plus injection computer or co-
ded solenoid valve electronic unit).
82
REPLACING THE DECODER UNIT ALONE
A new decoder unit is not coded. Once fitted to
the vehicle, the codes of both keys must be pro-
grammed so that it is operational (see program-
ming procedure).
NOTE : if the decoder unit alone is replaced, no
operation is carried out on the injection computer
or coded solenoid valve. It retains the same en-
gine immobiliser code.
IMPORTANT: when a decoder unit has been pro-
grammed with the key code, the code cannot be
erased and no other code may be memorised in its
place.
SPECIAL NOTES
Diesel vehicles
On these vehicles, the decoder unit is identical to
the decoder unit of a petrol immobiliser system.
When replacing it the new "diesel" part must be
configured by means of the XR25 test kit.
This configuration will enable the decoder unit to
check that the coded solenoid valve is operating
correctly (indicated by the immobiliser warning
light) (see diesel configuration).
Vehicles fitted with a remote control
After replacing the decoder unit carry out a resyn-
chronisation operation (see simple resynchronisa-
tion procedure, section 88).
82-6
5.Check the immobiliser system operates cor-
rectly with both keys.
Ignition off, the red immobiliser warning light
should flash 10 seconds after switching the
ignition off (slow flashing). Bargraph
10 LH
should be illuminated. The vehicle should not
start when other keys are used.
NOTE : to simulate prevention from starting,
before switching the ignition on, wait for the
red warning light to flash slowly.
Enter on
the XR25, ignition still off (bargraph
9 LH illu-
minates).
Switch the ignition on, the red immobiliser
warning light should flash more quickly and
the vehicle should be impossible to start.
6.The procedure is complete. After switching
the ignition off and on again (for more than 2
seconds), check that the vehicle can be started
with both keys.
Diesel configuration
On diesel vehicles the decoder unit must be confi-
gured in "diesel" using the XR25.
1.Ignition off, XR25 connected (ISO selector on
S8).
Enter code (fiche n° 56),
bargraph
1 RH must be illuminated.
2.Enter programming mode
Bargraph
3 RH must illuminate.
The configuration is complete.
IMMOBILISER
Coded key immobiliser system
PROGRAMMING PROCEDURE
The procedure is carried out using one key.
The XR25 must be used for this procedure to lock
the key programming.
1.Ignition off, connect the XR25 to the vehicle
and set the selector to S8.
Enter code (fiche n° 56),
bargraphs 19 RH and 19 LH must be illumina-
ted (programming not carried out). If both of
these bargraphs are not illuminated, replace
the decoder unit (this unit has already been
used).
2.With one of the keys switch the ignition on
for approximately 2 seconds (without starting
the engine). Bargraph 18
LH illuminates and
bargraph
19 LH extinguishes.
The red immobiliser warning light flashes.
3.Switch the ignition off and start command
G60* to lock the programming. The red immo-
biliser warning light should flash (slow flas-
hing). Bargraphs 19 RH and 18 LH should be
extinguished.
4.Switch the ignition on for a few seconds (wi-
thout starting the engine) to send the code to
the injection computer or the coded solenoid
valve.
