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

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-

junction.
Te rm inals no. 3 and 5 of the H fuel-pump

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.

THE ANTI-START FUNCTION
R
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.

COOLING - EX HA U ST - FU EL TANK
IMPORTANT
Duri ng the interventions affecting t he
petrol tank and the fuel supply circuit one
must not smoke or bring incandescent
parts near the work-place.
The emptyi ng of the tank does not require
taki ng apart the tank. Ac ces s is allowed
through the inside of the car (i.e. the boot). To take apart:-the carpet of the boot;
-t he lid of the visiting mouth (by taking
off th e four screws);
-the c lick-collar 1 is ta ken out by means
of the MOT 1202 device;
-a t ube is adapted to the A outlet, which
should be long enough to be introduced into a
ve ssel outside the car. The
H relay of the petrol-pump is taken out of
the fuse box located in the engine compartment,
and term inals 3 and 5 of the re lay connector are
shunted, thus ensuring the operation of the petrol
pump ( 12 V).
Th e operation of the pump will be stopped
when an intermittent leakage of the petrol is no-
ticed. The shun t is taken off.
The relay is mounted.
