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.

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.

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 :
• Under normal operating conditions, the oil level is only measured if the ignition has been switched off for
over one minute; otherwise the old oil level value is re-displayed.
If a fault is detected, however, an oil level measurement is made each time the ignition is switched on to
check if the fault is persisting.
• It is normal to find that the oil level is not always the same:
- parking on a slope,
- too short a wait after running the engine for a short moment (especially when the oil is cold), ...

OPERATION
The sensor consists of a wire with a high
coefficient of resistance. When a current passes
through the wire it does not have the same
thermal conductivity when it is immersed in a
liquid as when it is in the open air.
After a fixed time a voltage difference is obtained
at the sensor terminals depending on the depth of
immersion of the wire. This voltage difference is
recorded by the electronic unit which manages
the level display function and also controls the
"low oil level" warning light display on the
central liquid crystal display.
When the ignition is switched on, the central dis-
play shows the oil level in a series of "blocks" for
approximately 30 seconds, before returning to
displaying the trip mileometer and total mileome-
ter functions (or "odometer" function).
NOTE : Turning the trip mileometer reset button
before the end of the timed period will display
the "odometer" function.
LOOKING FOR FAULTS
If a short circuit or an open circuit is detected
when the oil level is measured, the display will im-
mediately show the trip mileometer / clock dis-
plays.
CHECKING
The sensor resistance must be between 6 and 20
ohms.
The sensor is deemed to be in short circuit for a va-
lue lower than 4 ohms.
The sensor is deemed to be in open circuit for a va-
lue higher than 22 ohms.

REMOVAL - REFITTING
Disconnect the battery and set the wheels
straight.
Remove the steering wheel and the two half cow-
lings (for vehicles with an airbag, refer to the re-
moval of the rotary switch on the following page
or section 88 for special notes on removing the
steering wheel).
Special notes for vehicles with an airbag
Before removing the assembly, the position of the
rotary switch under the steering wheel must be
noted:
- by ensuring that the wheels are straight on re-
moval so that the strip may be positioned in the
centre,
- by immobilising the rotary switch rotor using
adhesive tape.
Slacken the bolt (C) then sharply tap the screwdri-
ver to release the cone.
84
Special notes for refitting
Fit the mounting with its components, connect
the various connectors and push the assembly
back against the steering column.
Continue refitting and do not lock bolt (C) until
the two half cowlings are refitted, so that the
stalks may be aligned with the dashboard and the
instrument panel.
This operation is made easier by a cut-out section
giving access to bolt (C) in the lower half cowling.
For vehicles with an airbag, observe the re-
commendations in the section " Special notes for
the rotary switch under the steering wheel" on
the following page or section 88 (driver’s airbag).
