Disconnect the battery.
Lift the rear bench seat (depending on
equipment).
Remove the pump and sender unit steel cover.
Disconnect the electrical connector (1).
Release the clips (2).
Then disconnect the fuel supply pipe (3) (green
marking on the quick-release union) and the fuel
return pipe (4) (red marking on the quick-release
union) using the special pliers Mot. 1265 or Mot.
1265-01.
IMPORTANT: When the pipes are removed, fuel
may be splashed out due to the residual pressure
in the pipes. Take appropriate precautions.
IMPORTANT :
During any operation on the fuel level sensor
you must observe the following precautions:
- Do not smoke.
- Keep all flames or incandescent objects away
from the working area.
REMOVAL OF THE PUMP - SENDER ASSEMBLY
The pump and sender unit assembly may be
removed through the inspection cover under the
rear bench seat and the fuel tank does not have to
be removed.

Tighten the mounting nut on the fuel and sender
unit assembly to a torque of 3.5 daN.m using the
tool Mot. 1264-01, holding the sender unit to pre-
vent it from rotating.
Make sure that the connector is firmly locked and
that the quick-release unions are securely clipped
on (with 2 O-ring seals)
Reconnect the battery.
CONNECTION
Disconnect the connector and the pipes on the
sender unit side.
Remove the mounting nut (5) of the pump and
sender unit using tool Mot. 1264-01.
Slacken the nut, remove the tool, unscrew the nut
by hand and remove it.
Remove the pump and sender unit assembly.
NOTE : If several hours may pass between
removing and refitting the pump and sender unit
assembly, refit the nut to the fuel tank to prevent
it from distorting.
REFITTING OF THE PUMP AND SENDER UNIT
ASSEMBLY
Special notes
Check that the seal is in good condition and re-
place it if necessary.
Fit the seal on the fuel tank first before fitting the
assembly.
Refit the pump and sender unit assembly in the
fuel tank by aligning it so that the indexing arrow
(F) is positioned in line with the longitudinal axis
of the vehicle, pointing towards the rear of the
vehicle.

INSTRUMENT PANEL

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.

OPERATION
A thermistor transmits a variation in resistance to
a receiver, depending on the coolant
temperature, and a threshold overshoot switch
illuminates the warning light on the instrument
panel when the temperature reaches 118°C.
CHECKING
Connect an ohmmeter between track 1 (K and E
engines) or track 2 (F engine) on the sensor and
vehicle earth.
Correct value : 160 to 1 250 Ω.

When refitting the computer, it MUST be moun-
ted on the vehicle before its connectors are re-
connected.
The arrow on the computer must point towards
the front of the vehicle.
Vehicle fitted with airbag(s)
Lock the computer using the XR25 and command
G80* (ISO selector on S8 code D49).
When this function is active, all the trigger lines
are inhibited, the airbag warning light on the ins-
trument panel and bargraph 14 LH on the XR25 il-
luminate (new computers are supplied in this
condition).
When refitting the computer:
- Mount it on the vehicle (the arrow on the
computer must point towards the front of the
vehicle).
- Connect the 30 track computer connector and
carry out a check using the XR25.
If everything is correct, unlock the computer using
command G81*.COMPUTER
Several types of unit may be found:
- one computer for pretensioners only.
- one computer for pretensioners and airbag(s).
Depending on function, these computers have:
- an electromagnetic safety sensor,
- a decelerometer for the airbags
- an ignition circuit for the different pyrote-
chnic systems,
- a power reserve,
- a diagnostic and detected fault storage circuit
(except pretensioner only),
- a control circuit for the warning light on the
instrument panel (except pretensioner only),
- a K - L communication interface via the dia-
gnostic socket (except pretensioner only).
IMPORTANT
Before removing the computer:
Vehicle with pretensioners only (no air-bag) :
- Switch off the ignition.
- Remove the feed fuse (see fuse allocation) and
wait for 5 minutes for the reserve capacity to
discharge.
- Disconnect the computer connector to avoid
any risk of triggering.
- Ensure no-one is in the passenger compartment
during the complete operation on the compu-
ter.

WARNING LIGHT ON THE DASHBOARD
This warning light controls the pretensioners and
airbags, except for vehicles fitted with pretensio-
ners only.
It should illuminate for a few seconds when the
ignition is switched on, then extinguish (and
remain extinguished). If it does not illuminate
when the ignition is switched on, or illuminates
when the vehicle is being driven, there is a fault in
the system (see fault finding section).
IMPORTANT : the systems MUST be checked by
means of the
XRBAG, following:
- an accident which has not given rise to
triggering,
- theft or attempted theft of the vehicle,
- before the sale of a used vehicle.
These systems are not triggered in the case of:
- a lateral impact,
- a rear impact.
When it is triggered the pyrotechnic gas
generator produces an explosion combined with
light smoke.
NOTE : With pretensioners only,the computer has
a single sensor (electromechanical).
OPERATIONS ON THE TRIGGER LINES
If a fault is noted on one of these lines, the
component must be renewed and not repaired.
This safety equipment cannot be subjected to any
conventional wiring or connector repair opera-
tions.
The airbag trigger wiring is integrated into the
passenger compartment wiring loom . To make
replacement easier, cut the two ends of the faulty
wiring and run the new wiring along the same
routing, alongside the passenger compartment
wiring loom.
IMPORTANT : When fitting the new wiring, en-
sure it is not in danger of being cut or rubbed and
that the original wiring cleanliness is respected.
NOTE : The trigger lines are supplied by the Parts
Department in a kit containing both airbag and
pretensioner wiring.
OPERATION WITH AIRBAG(S) AND PRETENSIONER
EQUIPMENT
When the ignition is switched on, the
warning light illuminates for a few
seconds then extinguishes.
This computer is then on standby and notes dece-
lerations of the vehicle using the signal measured
by the integral decelerometer.
When a frontal impact of sufficient strength oc-
curs it triggers the simultaneous ignition of the
pyrotechnic generators of the two seat belt pre-
tensioners after receiving confirmation of detec-
tion of an impact by the electromechanical safety
sensor.
Under the action of the gases generated by the
system, a piston is displaced in its cylinder,
carrying with it a cable connected to the
corresponding central catch, thus enabling the
seat belt to be retracted (see pretensioner
section).
If the frontal impact is greater than this, the dece-
lerometer triggers the ignition of the pyrotechnic
gas generators which inflate the driver and pas-
senger airbags once the impact has been valida-
ted by the electromechanical safety sensor.
