IDENTIFICATION
DIAGNOSTIC
Special tool : CLIP tester – TECHNIC for measuring the battery voltage and the absorbed
intensity in the starting stage.
OPERATION ABNORMALITIES THAT MIGHT BE NOTICED
- Battery failure = large voltage drop on starter during engine starting stage.
- Blocked starter = the absorbed current is very high.
- Solenoid failure = the absorbed current is very low.
In order to perform the measurements, it is necessary the engine drive by means of the starter,
but stopping the engine starting.
To do that, disconnect the RPM sensor (located on clutch casing).
REMARK:
After performing this checking, erase by means of the CLIP tester, the possible failures
memorized by the computer.

Injection system
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.

ANTI-STARTING INDICATOR
When setting the contact on, UCE injection is receiving from UCE DECODER a code, whi
ch is compared
with the one previously memorized; if the two codes are matching, then the engine starting is author ized.
After contact setting on, anti-starting indicator which was previously blinking, will light for
three seconds then it will go off, confirming in this way, the key recognizing.
If the key is not good, after setting on the contact, the anti-starting indicator will start blinking
faster and the engine starting will be impossible.
OBSERVATION:
For details regarding the vehicle anti-starting system, see chapter 82 “Anti-starting system”.

injection system wiring are not allowed. It is forbidden the engine starting with the battery connected to a charging / starting
unit. The battery recharging is t o be pe rformed only aft er disconnecting it from the vehicle

PRINCIPLE
In engine normal operation conditions at warm, the RC O value is varying between a high and
a low limit, in order to obtain the nominal idling regime. Further to an operation dispersion
(ru nning in, engine clogging, etc), it may be possible that RCO idling value to be situated next to
the lower and higher values. The ad aptive correction of the “RCO idling ” parameter is allowing obtaining of slow variations
of the engine air requirement, so that RCO value centering on an average nominal vale is obtained.
Th is correction is becoming effective unless the water temperature is over 80°C, at 20 seconds
after engine starting and if it is in the nominal idling adjustment phase.
“R CO IDLING” AND “ IDLING EN RICHING ADAPTATION” VALUES
PARA M E T ER RE COM MENDE D VAL UE
PR006: Engine regime 750 rot/min
PR022: RCO idling 5%< X < 12%
PR031: Idling enriching adaptation 80 < X < 176
At each engine stopping, the injection computer is controlling the performing of a new position-
ing of the step-by-step engine, bringing it to the bottom limit. This function so called “re-setting”, is
main tained for 8 seconds.
INTERPRETATION OF T HE PREV IOUSLY M ENT IONED PARAM ETERS
In the situation of an air excess (infiltration air, valve body inadequate attachment, etc), the idling
re gi me will increase and the “RCO idling” va lue will decrease in order to return to the nominal
idling regime. The value of the RC O idling adaptive correction will decrease in order to centering
again the id ling adjustment operation.
In case of an air lack (clogging, etc) the reasoning is opposite: “ RCO idling” is increasing, and
the value of the “ RCO idling” adaptive correction will increase in order to center again the idling
opera tion on an average nominal value.
IMPORTANT: After erasing the failures memorized by the injection computer, it is necessary
to start the engine then stop it, in order to achieve in this way the re-setting of the step-by-step
en gine. Start then again the engine and let it idle run until reaching the nominal idling regime, in
or der to achieve a correct re-setting of the adaptive correction.

DIAGNOSTIC CONDI T IONS
If wh en setting on the contact, with stopped engine, one of the following conditions is accom-
plished: -air temperature, red by the air temperature sensor, is not situated between –6° and 119°C.
-w ater temperature, red by the water temperature sensor, is not situated between –6° and
119°C.
-atmosphe ric pressure is under 775mbar,
then the OBD diagnostics are not authorized until the next contact setting on. In order to have a correct operation of the OBD diagnostic system, no electric failure of the
injection system must exist, even if the lighting of the OBD indicator is not established. The catalyst and oxygen sensor diagnostics can not be performed in the same time, but one
after other.
When the catalyst or oxygen sensor diagnostics are under operation, the canister purging valve
is closed, and the adaptive values are “blocked” at the last existent value prior to a.m. diagnostics
starting. TESTS PERFORMING LOGIC
-Solve fa ilures of electric nature.
-Erase a ll failures by means of the CLIP tester
-Perform the “teaching” stage of all adaptive values by the injection system (if necessary).
OB D COMPLETE ACTIVATION BY MEANS OF CLIP TESTER
-Erase all memorized failures.
-Erase the “learned” values from UCE injection if further to an intervention on an injection
system component, a disturbance of the “learned” values took place (step-by-step engine, flywheel
or RPM sensor, etc).
RETENTIONS (“LEARNINGS”) NECESSARY FOR UCEINJECT ION FOR OBD DI AGNOSTIC
〈 COUPLING/SUPPLY RATE LEARNING (state “ET014 = cylinder recognition 1” is PER-
FORMED with running engine). This is to be performed as following:
-a deceleration with “cutting” of the petrol injection in the third gear of the gearbox, be-
tween 3000-3500 rot/min for at least 2 seconds,
-a second deceleration with ”cutting” of the petrol injection in the third gear of the gearbox,
between 2400-2000 rot/min, for at least 2 seconds.
〈 MIXTURE ENRI CHING ADAPTIVE LEARNING
In order to do that, it is necessary that vehicle is running observing in the same time the pressure
ranges men tioned in the chapter “ Enriching adaptive correction”.
〈 State “ET202 = OBD diagnostic of combustion misfires taken into consideration” must be
AC TIVE.
