REFITTING
It is VITAL to remove the small filter (3) situated at
the bottom of the system, using a pair of thin-
nose pliers, and replace with a new filter.
The outer part serves as a seal and locks on
tightening the actuator.
Replace, in the following order : the seal at (4) of
the "banjo" return connection (5) ; the new
activator (1) fitted with an external filter, along
with the the two seals at (6) and (7).
Tighten the actuator to a torque of 3 daN.m
using socket Mot. 997-01.
Place the new protective cover (2)on the actuator.
Reconnect the two terminals to the connector.
Reconnect the connector itself.
Replace the protective sheath on the wiring,
along with the retaining clip.Bleed the diesel circuit using the priming pump
before starting the engine.

To remove the terminals for the pump
connector:
1) Pull the yellow guide to release it from the
terminals, then press the two tabs on either
side of the connector.
2) Extract the yellow guide.
3) Pull the wire to be removed.
4) The terminal is held in place by two small tabs,
one on each side; using a screwdriver, move
one of the tabs to one side (the action of
pulling on the wire prevents the tab from
going back into place.
5) Using a screwdriver move the other tab to one
side.
The terminal may now be removed from the
connector.Remove the protective sheath grouping the pump
actuators.

FUNCTION : it acts on the flow in proportion to altitude ; if the vehicle is running at
an altitude greater than or equal to 1 000 metres, the computer reduces the flow by
3 mm
3/stroke. The conventional flow is reestablished if the vehicle runs at an alti-
tude lower than 900 metres.

On this type of vehicle, the replacement of the
solenoid valve and of the coded electronic unit (A)
requires the removal of the injection pump from
the engine.
REMOVAL
With the pump on the bench, remove the protec-
tive fittings at (B).
These are secured by shear bolts which may be re-
moved either :
- using a small cold chisel or a punch and hitting
on the conical heads of bolts (C), (D) and (E)
to loosen them,
- using tool Mot. 1372 for bolt (F), drilling it
using the 4 mm diameter drill (drilling depth
approximately 4 mm) and the large diameter
drilling guide tube on the fitting side (2).
Use extractor (3) and its handle to remove it .
REFITTING
Tighten the fuel cut off solenoid valve to a torque
of 2 daN.m.
Refit a heat shrink cover on the fuel cut off sole-
noid, ensuring the wiring is correctly routed.
Refit the fittings using shear bolts and observing
their location and that of the spacers,
(depending on fitting).
IMPORTANT : using a torque wrench, tighten the
bolts, then remove the bolt heads by bending
them using a tube inserted in the bolt heads.
Location of bolts :
D :
∅ 5 x 25 mm ; torque =0.55 daN.m
C and F :
∅ 6 x 40 mm ; torque =1.2 daN.m
E :
∅ 5 x 33 mm ; torque =0.55 daN.m
Refit the cable of the fast idle speed LDA and
tighten the cable grip, leaving 2 mm play.
Refit the injection pump on the engine.

Load potentiometer
13
In the factory, vehicles are programmed with the full load position. (memorising the voltage delivered by the
potentiometer in the full load position). This value is used to adjust the load potentiometer after it has been
replaced. It is therefore essential, if the diesel injection computer has to be replaced during the vehicle’s li-
fetime , to carry out this programming (G31*).
If it is necessary to replace the load potentiometer, in order to adjust it we compare the voltage delivered by
the potentiometer in full load position, with the value memorised. The new potentiometer is said to be cor-
rectly adjusted when the two voltages are equal. This is displayed on the
XR25. G32* indicates the diffe-
rence in voltage between the value memorised and the one from the potentiometer. The adjustment is cor-
rect if this value is equal to 0 in the full load position.
The potentiometer and the computer cannot be replaced at the same time (if necessary, replace the poten-
tiometer first and then the computer).
REPLACEMENT OF THE LOAD POTENTIOMETER (operation to be carried out by two people)
Remove the three terminals for the load potentiometer from the 10 track pump connector (see method
described in section 13 "Advance solenoid valve").
Remove the two bolts mounting the faulty potentiometer, extract this, and fit the new potentiometer .
Hand tighten the two bolts mounting the potentiometer but do not lock them - it should be possible to turn
the potentiometer body .
Connect the
XR25, and switch on the ignition.
Set the selector to S8.
Enter code
Press down on the accelerator pedal (full load position). Do not act directly on the load lever.
Holding the full load position, turn the potentiometer body until the value 0 appears on the XR25 display (if
you are too far from the 0 value, the screen will display HL , which means "Hors Limite"= "Off limits". Just
to turn the potentiometer body to obtain the display of a decimal value).
Tighten the two bolts mounting the potentiometer in the full load position, when the value read is 0. D

DPCN LUCAS injection computers are configured before sale to "with air conditioning". If the vehicle is not
fitted with an air conditioning system, use command G50*4* on the
XR25 to carry out the "no air conditio-
ning " programming.
DPCN LUCAS "injection computers are configured before sale to "with power assisted steering " (power as-
sisted steering with pump assembly). If the vehicle is not fitted with a power assisted steering pump as-
sembly, use command G50*9* on the
XR25 to carry out the "no power assisted steering pump assembly"
programming.then

COMPUTER CONFIGURATION IN RELATION TO AIR CONDITIONING.
For vehicles equipped with air conditioning , enter G50*3* on the XR25
For vehicles without air conditioning , enter G50*4* on the XR25 .
COMPUTER CONFIGURATION IN RELATION TO THE PAS (POWER ASSISTED STEERING PUMP ASSEMBLY)
The vehicle may have two types of PAS assembly :
-a
PAS assembly including a high pressure pump driven by a belt. In this case, the computer must be
configured without PAS : enter G50*9* on the
XR25,
-a
PAS assembly with a pump assembly which is driven electrically and controlled by the injection compu-
ter. ( this type of
PAS is fitted in all vehicles which are also equipped with AC). In this case, the computer
must be configured with PAS : enter G50*8* on the XR25.
IMPORTANT : according to the above explanations, only two types of combination are possible for the illumi-
nation of bargraphs 18 and 19.
