Removal - Refitting
The dashboard must be partially removed to re-
move the decoder unit.
Remove:
- the steering wheel with the wheels straight,
- the half cowlings under the steering wheel,
- the knee protector under the steering column,
- the lights and wiper controls,
- the instrument panel surround,
- the instrument panel,
- the ashtray, its mounting and the two dash-
board mounting bolts on the heating unit,
- the trim at the bottom of the dashboard on the
driver’s side,
- the two speaker grilles on the dashboard,
- the dashboard mountings.

Move the dashboard as far back as possible, dis-
connect the decoder unit and remove the two
mounting bolts (B) using a small ratchet fitted
with a Torx 20 socket.
•A red immobiliser warning light on the instru-
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).

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.

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.

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).

Remote control for door locking

.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.

Replacing or adding a remote control without im-
mobiliser function without replacing the decoder
unit.
If the vehicle does not have an immobiliser, the re-
mote control does not have a special number. A
key head without a number may therefore be or-
dered.
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-

the transmitter correctly towards the receiver.
If the procedure fails it will be necessary to

control only).
4.The procedure is complete - check that the
doors lock correctly.
Simple resynchronisation procedure
This procedure allows the remote controls to be
reset with the decoder unit (rolling code).
This procedure is used:
- when the remote control code no longer lies
within the reception range of the decoder unit
(over 1,000 consecutive presses on the remote
control, away from the vehicle).
- when replacing a decoder unit alone (new de-
coder unit),
- when replacing a remote control if the decoder
unit is new (replacing a kit).
REMINDER: when replacing or adding a remote
control with immobiliser function without repla-
cing the decoder unit, refer to "Replacing or ad-
ding a remote control with or without immobili-
ser function without replacing the decoder unit"
(specific resynchronisation procedure).
