AIM:
To avoid accidental fire s owing to fuel leaks, which can be caused by an accident.
F
UNCT IO NING:
The shock-sensor lies in the engine compartment: it is mounted on the left-side shock-
absorber column. Du ring a shock, the ball of the sensor goes out of its slot, a nd thus achieves the breaking
of the electri c c ircuit be tween the relay commanding the petrol-pump and t he pe trol-pum p
itself.
PLACING B ACK THE SH OCK-SENSOR IN OPERAT IONAL MO DE
In order to resume the functioning of t he shock-sensor it will suffice to press its top,
and thus replace the ball in its former position. BREAKING FUEL SUPPLY

SPE CIAL DE VICE S
Tu ning pincers “CLIC”
It is recommendable to do the inspection
of the fuel pump-fl ow through t he re turn fue l
hose which is connected on the pump-level
transmitter set.
I
MPORTANT!
During these operations it is compul-
sory:
-not to smoke or handle incandes-
cent obje cts at the working place;
-to ensure protection from the petrol
projections due to residue pressure left in
the ch anneling during the taking-apart.
PUMP-FLOW INSPECTION
The re turn c hanneling no. 1 of the fuel
supply is disconnected.
A hose is connec ted on the junct ion
whose end i s introduced in a gra ded ve ssel
(from 0 to 2000 ml) Term inals 3 and 5 of H relay (lying in
the fuse-box of t he motor-compart ment) of
the petrol pump are shunted. Within a minute, the fl ow of t he pump
must be min. 1.3 lite r at the voltage of 12
V .
If the fl ow is not corre ct, the suppl y
voltage of the pump is inspected (t he flow
d ecreases by approx. 10% for a 1 V
voltage-decre ase).

CAUTION!
When the fuel circuit is opened, any
petrol jet due to residue pressure must be
averted by means of a gauze.
The air-filter is taken apart .
The fuel supply hose is disconnected.
The MOT 1311-04 deri vation junction
is connected onto the ramp, then the fue l-
s upply channelling is re-connected onto the
junction.
Te rm inals no. 3 and 5 of the H fuel-pump
relay (l ocated in the engine fuse -box) a re
shunted.
Pressure must be 3+/-0.2 bar.
By applying a 500 mbar depression on
the pressure-regulator, the pre ssure of the
fuel must be 2.5+/-0.2 bar.

DIAGNOS TICATION
S pecial device: CLIP - SAGEM-TECHNIC TESTER which measures the battery
voltage and the intensity absorbed by the starter.
ANOMALOUS FUNCTIONING THAT CAN BE SETTLED
-Battery failure –contact drop on the starter when starting the engine.
-Blocked starter (t he absorbed curre nt is very high);
Coupling relay defect (the current absorbed is very weak).
In order to do the measurements one must carry t he engine in starter mode, thus pre -
venting the engine to run.
To do t hat, the revolution sensor (located in the c lutch cra nkcase) should be t aken apart .
Remark: After doing these tests, erase the possible defects memorized
by the calculator with the tester.

The water - temperature sensor
This sensor (no.1) sends the inform ation concerning t he water t emperature to t he c alcu-
lator, and ot her i nformation is sent t o the on-board indicator, which will di splay water
temperature . In case of emergency regarding water t emperature , the calculator will command the
lighting of the water-tempera ture alert indicator on the board. In keeping with the water-temperature information received by the calculator, it will
command:
-the injection system;
-the relays for the command of the motor-ve ntilator e ngine cooling group.
When setting the contact on, the water tempera ture indicator, placed on the instrument
panel, shall be lighted for 3 seconds then it shall turn off.

So, after setting the contact off, during next 2 minutes from engine stopping, the water
temperature reaches the value of 102 C and the injection computer is then control ling the
cooling blower starting at low speed. When the tempera ture is lowering at 96 C, the blower will be stopped ; its operation
must not be over 10 minutes after engine stopping. PLACING OF ELEMENTS

THE ANTI-START FUNCTION

EPLACING UCE INJE CT IO N CAL CUL ATOR
The UCE injection
calculator is delivered without a code, but it is able to memorize a code.
When mounting a new c alculator, it will have to memorize the code anti-start fuction
singularity of this car, then one has to check if the a nti-start function is operational. In
order to do that, the following operations must be done: -the contact is set for a fe w seconds, then it is taken out;
-after t aking out the key, the anti-start function is actived.
I
NSPE CT ING THE ANT I - ST ART FUNCT IO N
Take the key out of the contact and after 10 seconds the anti-start light indicator on the
board must begin to flash on and off. When setting the contact on, the anti-start ing indicator must turn off.
THE INFLUENCE OF THE AIR-CONDITIONINGON THE INJECTION SYSTEM
The air-conditioning installation ( AC) uses a variable cylinder-volume compressor.
There are the following connections between the air-co nditioning and the petrol injection system:
-pin no. 46 of t he injection calculator re ceives the i nformation “ solicit accelera ted
idle mode” when the button for t he air-conditioning i nstallation is pre ssed and the pres-
su re of the freon in the installation is above a limit.
-the i nformation “ absorbed power” does not infl uence the idle m ode re gime, but lets
the calculator know about the value of the couple taken by the compressor, and the calcu-
lator will opera te the step-by-step engine, through pins nos. 12, 41, 42 and 72, in order to
compensate for the couple fall. With the tester it can read in t he m enu : « Parameters l ist «
the power absorbed by the compre ssor, wich will be between 300 and 5000 W. The value
that is re ad will be of m inimum 300 W, irre spective of the coupled / uncoupled state of the
compressor.
-pin no. 10 of the injection calculator will command the E relay located in the fuse-
box of the engine compartment, which will couple the compressor.
The injection calculator c an prohibit the coupling of the AC compre ssor:
-it does not allow the coupling of the compresso r before 10 seconds after the starting of the engine;
-accordi ng to the couple re quired from t he e ngine by the driver - a nd in cert ain
s ituations according to the power absorbed by t he c ompressor - the calculator c an forbid or
authorize the starting of the compressor;
-if the water temperature is higher than, or equal to 11 5
oC, the therm ic prot ection is oper-
ated, which will not authori ze the start ing of the compre ssor; -the overload protection doe s not permit t he coupling of t he compressor when the
revolution ratio of the engine is over 5900 rot/min.
