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.

RE CO MM ENDATIONS
In order to perform this diagnostic, the pressure sensor must be not in
failure.
Conditions for diagnostic appl ication for memorized failure :
Se t the contact off and wait until the communication computer-CLIP tester
is lost.
Set the contact on, enter in dialog with the computer and eras e the memorized
failures. Act upon the starter for 10 seconds or make the engine idle running.
* If the failure is memor ized with OBD indicator on, check in the conte xt
part, if sta te “ET276 : Engine flywheel tooting dama ge” corresponding to
t he OBD indicator lighting request is affirma tive. In this case, proceed as
per bellow mentioned method.

If no failure has been found, there is a problem on the fuel supply cir cuit.
In this situation the following must be checked:
- Fuel filter
-F uel pressure and flow
-F uel pump condition
-F uel tank cleaning condition]
-I njector s conditions
Mend the fuel supply circuit.
Ensure that all failures are solved. Erase the memorized failures.
There is no need to erase the “adaptive values” memorized by the injection
computer. In order to check the correct reparation of the system, the following
conditions must be accomplished:
AF TER - No more electrical failures.
REPARATION - All “adaptive values” to be memor ized by the injection computer.
- Warm engine (minimum 75°C)
- Run at idling, all consumers being in use for 20 minutes (1 minute
