PURPOSE
To avoid the fire hazard due to the fuel losses, that may occur in case of an accident.
OPERATION
The hazard sensor ( 1) is placed in the engine compartment, being mounted on the left shock
absorber column.
In case of shock, the sensor ball l eaves its lodgement, t hus interrupting the electric c ircuit
between the control relay of the petrol electric fuel pump and the electric petrol pump.
HAZARD SENSOR RE-STARTING
The upper part of the hazard sensor is to be pushed to re-position the ball i nto its lodgement
and thus to re-start the sensor.

IMPORTANT
Duri ng this operation, it is obligatory :
- not - sm oki ng a nd not bri ngi ng
incandescent obj ects at the working pl ace; - protect against petrol splashing due
to residual pressure remained in piping
during their dismounting.
VEHICLES WITH FUEL RETURN
The checking of the fuel pump capacity is
recommended to be performed by t he fue l
return hose connected on the level transmitter -
pump assembly .
Disconnect the fuel return pipe ( 1).
Connect on the pipe a hose, one extremity
being introduced in a calibrated vessel, from 0
to 2000 ml. VE HIC
LES WITHOUT FUEL
RETURN
Disconnect the supply pipe from the fuel
electric pump assembly .
Connect on the pipe a hose, one extremity
being introduced in a calibrated vessel from 0
to 2000 ml.
Start the fuel electric pump by bridging the
3 and 5 terminals of the fuel pump H relay
(placed in the fuse and relays box from engine
compartment).
The pump output must be minimum 1.3 l /
min at 12 V.
If the output is not correct, check the pump
s upply voltage (capacity i s decreasing by
approximate 10% for a voltage drop of 1 V).

ANTI-POLLUTION
Pet rol vapors re-aspiration
OPERATING PRINCIPLE
The communication of the t ank with t he
atmosphere is done through the carbon can. The petrol vapors are retained when they are
passing through the active carbon from the carbon
can. By means of a purging valve controlled by a
RCO signal issued by UCE injection, the petrol
vapors are re-aspired through piping by the intake
manifold.
The flow section of the purging valve is
variable, subject to the balance given by the
magnetic field created by supplying the purging
valve coil and the power of the spring ensuring
the valve closing.
RE-ASPIRATION CONDITIONS
The can-purging valve is controlled by pin
4 of the UCE injection, in the moment when:
-w ater tempera ture > 20 ° C;
- air temperature > 10 ° C;
- engine is running over a certain im-
posed charge; -valve potentiometer is not in the posi-
tion acceleration pedal not pressed.
By using the CLIP tester, it is possible the
reading of the RCO value (opening cyclic
ratio).
The purging valve is closed for a value
smaller than 0.7%. OPERATION CHECKING OF THE
CAN PURGING VALVE
A defective operation of the petrol vapors
re-aspiration system, may lead to an unstable
idling or even to the engine stopping. First of all, check:
-circuit conformity (see the operating
diagram)
-piping condition between the can and
the fuel tank (sealing, circuit clogging).
The (B) piping coming from the tank shall
be clogged.
Connect a manometer (-3…+3 bar) at the
(M) connection for communication with the
atmosphere and check at idling if there is
depression. Is there depression?
YES – Set conta ct off. Usi ng a
vacuum pump, apply a 500 - mbar depression
at the (A ) piping connection of t he purging
valve. The value of the red depression must
not have a variation more than 10 mbar
wi thin 10 seconds.

Petrol vapors re-aspiration
If the pressure is varying more than 10
mbar, then the purging valve is defective and
the carbon can assembly is to be replaced. NO – When conditions for purging valve
controlling are accomplished and this one is
not opening, check its controlling electri c
circuit (between UCE injection pin 4 and
purging valve), from point of view continuity
or short-circuit. The RCO value of the signal received by
the purging value from the computer, may be
red by means of the CLIP tester in PR 023.
The minimal value is 0.7 % (corresponding
to the closing position of the purging valve).
LOCA TION – DISMOUNTING
The carbon can assembly ( 1) with
incorporated purging valve, is placed on the
front right wing lining. Disconnec t the piping ( 2) coming from the
tank and piping ( 3) to the engine.
Di sconnect the electric connector ( 4) of
the purging valve. Remove the can from the attachment
support. Perform the dismounting operations

CIRCUIT PRESENTATION
1 – Ho se for oil vapors re-aspiration, connected upstream of valve body between cylinder
head cover and air filter case (the circuit is used for middle and big charges).
2 – Hose for oil vapors re-aspiration, connected downstream of valve body between cylinder
head cover and intake manifold.
For a correct operation of the oil vapors re-aspiration system, the hoses must be kept clean
and in good condition.

OPERATION / DIAGNOSTIC
These vehicles are equipped with alternators with internal ventilation, incorporated voltage
regulator, and charging indicator on the instrument panel, which must operate as follows:
-w hen the contact is set on, the indicator is on;
-af ter engine starting, the indicator is off;
-i f indicator goes on during engine running, then it shows a charging failure.
INCIDENTS SEEKING
A. The indicator is not lighting when setting the contact on
Check : -the electric connections must be well done;
- the indicator bulb is not worn (when the circuit is mass connected, the bulb must be on).
