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the key is withdrawn from the ignition and this is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.

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.

5.Connect the XR25, setting the ISO selector to
S8.
Enter code
Bargraphs
19 RH and 19 LH must be illumina-
ted (programming not carried out).
6. With one of the keys switch the ignition on
for approximately 2 seconds (without star-
ting the engine). Bargraph 18
LH illuminates
and bargraph
19 LH extinguishes.
The red immobiliser warning light flashes rapi-
dly.
7.Switch the ignition off and start command
G60* to lock the programming.
- the red immobiliser warning light should
flash (slow flashing)
- bargraphs 19 RH and 18 LH should be ex-
tinguished.
8.Switch the ignition on for a few seconds,
check that the red immobiliser warning light
is illuminated permanently (diesel) or that
the injection warning light is flashing (pe-
trol).
9.Switch the ignition on for more than 10
consecutive seconds.
10.Switch the ignition off and wait for the red
immobiliser warning light to flash slowly.
Enter command
with the ignition still off (bargraph
9 LH illu-
minates).
Switch the ignition on, the red immobiliser
warning light flashes more rapidly.
Follow the procedure for entering the securi-
ty code (see procedure for entering the secu-
rity code), using the code number correspon-
ding to the old kit. This erases the old code
memorised in the injection computer or the
coded solenoid valve.
IMMOBILISER
Coded key immobiliser system
REPLACING A KIT
(decoder unit plus two key heads)
If a kit is replaced it will be necessary to:
- programme the codes of the 2 new keys in the
new decoder unit (supplied uncoded).
- erase the old code in the injection computer or
coded solenoid valve using the security proce-
dure (the code number for the old kit should be
requested from the local assistance network,
example Delta Assistance for France, NVSR for
the UK by fax only)
IMPORTANT : to erase the old code (memorised in
the injection computer or coded solenoid valve
electronic unit), the procedure described below
must be followed in the correct order.
The code in the injection computer or coded sole-
noid valve cannot be erased with the security code
(using the number for the old kit) unless the deco-
der unit fitted to the vehicle has been program-
med with a different code (which is the case in the
following procedure).
NOTE : if the security code is entered when the
decoder unit has the same code as the injection
computer, or coded solenoid valve, it will not be
decoded.
1.Fit the metal inserts from the old keys into
the new key heads.
2.Note the number of one of the old keys to
obtain the security code number.
3.Remove the decoder unit with the ignition
off.
4.Fit the new decoder unit, ignition off.

11. Switch the ignition off and on again for a few
seconds without starting the engine to pro-
gramme the immobiliser code for the new kit
in the injection computer or coded solenoid
valve. The red warning light should illuminate
for 3 seconds then extinguish.
For diesel :
Ignition off, configure the decoder unit to
"diesel" (see diesel configuration using command
)
Bargraph
3 RH should illuminate; the configura-
tion is complete.
NOTE
- petrol vehicles: Using the XR25, check the in-
jection computer has been programmed with
the code. Bargraph
2 RH (immobiliser) should
be extinguished.
After entering
the display should show
The injection computer has been correctly co-
ded.
If the display shows
the injection computer is still uncoded.
- diesel vehicles: When the ignition is switched
on, check the immobiliser warning light extin-
guishes after 3 seconds.
IMMOBILISER
Coded key immobiliser system
NOTE: On petrol vehicles use the XR25 to check
that the injection computer has been correctly de-
coded (in injection fault finding).
Connect the XR25 to the diagnostic socket , posi-
tion the ISO selector and enter the injection code :
bargraph 2 RH side (immobiliser) should be illumi-
nated.
After entering
the message
should appear on the display on the XR25. The
erasure is complete.
- If the display shows
there is a fault on the coded line. In this case,
repair the fault and start the procedure again.
- If bargraph 2 RH side (immobiliser ) is extinguis-
hed,
and the display shows (*22),
this shows that the injection computer code has
not been erased. In this case check the confor-
mity of the security code and repeat the proce-
dure.

IMPORTANT: if an uncoded injection computer or
solenoid valve is being tested from stock (test
part), the decoder unit
MUST NOT be supplied du-
ring the operation.
If the decoder unit is supplied, switching the igni-
tion on causes a coded signal to be sent from the
decoder unit to the injection computer or coded
solenoid valve (and the code is then program-
med).
To avoid memorising a code which could make
the injection computer or coded solenoid valve
electronic unit unusable after the test, the fuse
(+ before ignition feed) for the decoder unit
must be removed (fuse showing the door locking
symbol). This prevents the coded signal being sent
when the ignition is switched on (the computer or
the coded solenoid valve electronic unit remains
uncoded).
For petrol vehicles, the computer used for the test
MUST have the same Part Number as the original
computer on the vehicle (test computer may be
damaged).
Checking (on petrol vehicle only)
If the test computer is to be returned to stock, it is
possible (before it is removed) to check using the
XR25 that the computer has not been coded du-
ring the test (example : incorrect operation).
Connect the XR25 to the diagnostic socket.
Position the ISO selector and enter the injection
code: bargraph
2 RH (immobiliser) should be illu-
minated.
After entering
the message
should be displayed on the XR25.
This shows that the injection computer is not co-
ded and may be returned to stock.
If bargraph
2 RH (immobiliser) is extinguished and
after entering
the message
is displayed on the XR25, this shows that the
computer has been programmed with the immo-
biliser code (incorrect operation). In this case the
computer must be decoded before being returned
to stock.
The procedure for decoding consists of replacing
the decoder unit on the vehicle with another de-
coder unit with a different code (with its key
head) and entering the security code for the vehi-
cle (security code number should be requested
from the local assistance network, example
DELTA
Assistance for France, NVSR for the UK by fax on-
ly) using the number in the head of the key for the
vehicle.
Ignition off, fit in place of the original decoder
unit on the vehicle, a decoder unit coded with a
different number (the procedure will not work
with an uncoded decoder unit or one which has
the same code as the injection computer).

NOTE : this fault may be shown by the XR25 (in
injection fault finding).
Connect the XR25 and enter the injection code.
The fault is shown by bargraph 2 RH side.
After entering
the message
on the XR25 display indicates a fault on the coded
line.
Diesel vehicle
If a system fault is detected by the decoder unit
when the engine is running, the red immobiliser
warning light will illuminate permanently until
the ignition is switched off.
IMPORTANT: In this case, after repair, the fault
memorised in the decoder unit must be erased by
entering command
on the XR25 to allow the engine immobiliser sys-
tem to operate again.
NOTE: this fault may be shown by the XR25 using
fault finding for the decoder unit (fiche no. 56).
Connect the XR25.
Set the ISO selector to S8.
Enter code
The fault may be shown by bargraph
6 RH or LH
side. Switch the ignition on, the red engine immobiliser
warning light will flash (rapid flashing).
Enter the vehicle security code (number corre-
sponding to the original key number).
After entering the security code, the red warning
light will flash again.
The XR25 display should show
(in injection fault finding). This indicates that the
injection computer has been decoded.
Switch the ignition off, remove the decoded
computer and return it to stock.
Refit the computer and decoder unit to the vehi-
cle.
NOTE : When testing the injection using the XR25
on a vehicle without an immobiliser, bargraph 2
RH side will illuminate (*22 = 2 def = computer
not coded). This is normal.
SYSTEM FAULT, ENGINE RUNNING
Petrol vehicle
If a fault in the system is noted by the injection
computer when the engine is running, the injec-
tion warning light on the instrument panel will
flash during deceleration and at idle speed (en-
gine speed less than 1500 rpm).
IMPORTANT: In this case, after repair, the fault
memorised in the injection computer and the de-
coder unit must be erased by entering command
on the XR25 or by disconnecting the battery (ap-
proximately 30 seconds) to allow the engine im-
mobiliser system to operate again.

4.Enter mode
on the XR25 then the security code number
and validate using
-If the code is correct
is displayed.
Bargraph 10 LH extinguishes.
The engine may be started.
The vehicle is protected once more :
• approximately 10 minutes after switching
the ignition off (automatically),
• after disconnecting the battery.
-If the code is incorrect
is displayed.
Bargraph 10 LH remains illuminated.
The engine may not be started.
The red immobiliser warning light and the in-
jection warning light (depending on version)
flash.
Switch the ignition off, then repeat the proce-
dure for entering the code.
IMPORTANT: you may make 3 attempts to enter
the code. If, after the third attempt, the code is in-
valid, you must wait for approximately 15 mi-
nutes before making another attempt.
When this period has expired, switch the ignition
off and on again and 3 more attempts may be
made.
NOTE : This procedure does not decode the injec-
tion computer or coded solenoid valve (depen-
ding on the type of engine)- it only authorises the
starting of the vehicle.
REMINDER : The ignition must be switched off
and on again between attempts to enter the
code.

PROCEDURE FOR ENTERING THE SECURITY CODE
With this immobiliser system, the procedure for
entering the security code is managed by the de-
coder unit.
The code is entered using the XR25 only.
The security code can only be entered if the en-
gine immobiliser system is active. The red immobi-
liser warning light must flash when the ignition is
switched on (rapid flashing).
After determining the security code number (re-
quest from the local assistance network, example
DELTA Assistance for France, NVSR for the UK by
fax only) , carry out the following operations:
1.Ignition off, the red engine immobiliser war-
ning light should flash (slow flashing).
2.Switch the ignition on, the injection warning
light (petrol vehicle) illuminates for approxi-
mately 3 seconds then extinguishes, while the
red immobiliser warning light should flash
more quickly.
3.Connect the XR25 to the vehicle and set the
ISO selector on S8.
Enter code
Bargraph 10 LH should be illuminated (fault
finding fiche n° 56).

WIRING
Remote control for door locking
88
.GENERAL
These vehicles are equipped with an infrared or
radio frequency remote control with rolling code,
which prevents the code from being copied.
When a transmitter is replaced it will therefore be
necessary to resynchronise it so that the transmit-
ters are returned to phase with the decoder unit.
This remote control is only used for locking and
unlocking the opening elements (it has no effect
on the immobiliser).
IMPORTANT: this system cannot operate with
three remote controls (the decoder unit can only
manage two different rolling codes).
THE TRANSMITTER (PLIP)
Replacing or adding a remote control with immo-
biliser function without replacing the decoder
unit.
Order a spare key head using the number in the
head of one of the old keys or the label normally
attached to the keys when the vehicle is delivered
(eight alphanumeric characters).
If a key is being added or has been lost, remember
to order the insert with the key number.
Carry out the special resynchronisation procedure
using the XR25.
This procedure resets the remote control into se-
quence with the decoder unit (rolling code) and
should only be used if the decoder unit is not
being replaced (with immobiliser only).
1.Ignition off, connect the XR25 (ISO selector on
S8, code D56).
For vehicles fitted with an infra-red remote
control, enter command mode G04* (forced
protection mode) then switch the ignition on
again and enter the vehicle’s security code
(see procedure in section 82).
For vehicles fitted with a radio frequency re-
mote control, go to point 2.
2.Switch the ignition off and enter command
mode G32*.
From this moment, the operator has 10 se-
conds to carry out the next operation.
NOTE: The 10 seconds are shown by the illu-
mination of the red immobiliser warning light
and bargraph 17 LH on the XR25
(code D56,
fiche n° 56).
3.Press the remote control twice (the doors lock
and unlock and the red warning light extin-
guishes).
NOTE :
- When replacing a key head, resynchronisa-
tion of the second remote control (if fitted)
is not always necessary.
Check that the second control operates,
otherwise resynchronise it.
- If both remote controls (if fitted) are desyn-
chronised, two resynchronisation proce-
dures will have to be carried out (one for
each remote control).
IMPORTANT: To ensure that the infrared code
is correctly transmitted it is essential to direct
the transmitter correctly towards the receiver.
If the procedure fails it will be necessary to
restart from the beginning (infrared remote
control only).
4.The procedure is complete - check that the
doors lock correctly.
