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.

PUMP CAPACITY CHECKING
SPECIAL TOOLS
Pliers for “CLICK” collars.
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).

AT T E N T I O N !
When opening the fuel circuit, protect
by means of a gauze piece against petrol
s plashing due to residual pressure from
the supply circuit.
Dismount the air filter.
Disconnect the fuel supply hose.
Connect the MOT 1311-04 device on the
ramp, and then reconnect the fuel supply
piping to the connection.
Mount the manometer 0 ÷ 10 bar and
the flexible hose MOT 1311 – 01.Bridge the terminals

The measured pressure must be 3.5 bars.
Fo r vehicles with fuel circuit without return

WATER TEMPERATURE SENSOR
The water temperature sensor ( 1) is sending to UCE injection the information regarding water tempera-
tu re, and another information is sent to the indicator from the instrument panel, which will show the water
tem perature.
In case of an alert regarding the water temperature, UCE injection will control the lightening of
the water temperature indicator from the instrument panel.
Subject to water temperature, UCE injection will control:
- injection system;
- relays for controlling the engine cooling fan.
When setting the contact on, the water temperature indicator located on the instrument panel,
will be lighted for 3 seconds, then it will turn off.

If after the contact is set off, in the next 2 minutes from engine stopping, the water temperature
is reaching 102 °C, and t hen the injection computer i s control ling t he starting of the e ngine
cooling fan at low speed. When the temperature is lowering at 95°C, the engine cooling fan stopping will be controlled;
its operation must not exceed 10 minutes after engine stopping.

AIR CONDITIONING UNIT IS USING A COMPRESSOR
WITH VARIAB LE DI SPLACE M ENT
Th e connections injection/air conditioning, are the followings:
- pin 46 of the injection computer is receiving the information “ air conditioning
re que st” further to the air conditioning switch acting;
- pin 10 of the injection computer will transmit the coupling control of the air
co nditioning compressor by means of the “A” relay, if the coupling authorization conditions are
accomplished.
The information “power absorbed by compressor” displayed when performing diagnostic by
means of the CLIP tester, is related to the couple value taken by the compressor. This is of 300-
5000W, the minimal displayed value being of 300 W, regardless the compressor coupled / unc oupled
c ondition.
Th e injection computer is forbidding the compressor coupling in the following situations:
-at less than 16 seconds from engine starting;
-subject to the power requested to the engine by the vehicle driver.
-when th e acceleration pedal is fully pressed;
-i f the engine RPM is lowering till 550 rot/min (compressor is again coupling if the RPM is
r eachi ng to 1800 rot/min);
-if the wa ter temperature has increased to over 110° C;
-if the engi ne RPM is exceeding 6000 rot/min.
