〈 SIRIUS 32 with 90 pins computer is managing the ignition and the injection.
〈 For diagnostic, CLIP Sagem tester is to be used.
〈 The injection system in use is a sequential multi-point type, injection and ignition phases
controlling being based on the SIRIUS 32 computer program logic, starting from the signal received
from the RPM sensor.
〈The pr esence of the anti-pollution indicator OBD on the instrument panel, that is lighted for
3 seconds when setting the contact on, is specific to the vehicles observing pollution norms EURO
2000. The injection computer of these vehicles is provided with diagnostic system type OBD (“ On
Board Diagnostic).
〈 Idling regime correction is subject to:
-c limate maintenance on/off control (air conditioning)
-e lectrical balance on vehicle, as a result of connecting different electric consumers.
〈 EURO 2000 specific vehicles are provided with two oxygen sensors located in front of the
cata lyst (upstream oxygen sensor) and after catalyst (downstream oxygen sensor).
〈 At EURO 2000 specific vehicles, the fuel supply is performed at constant pressure (3.5 ±
0.2 bar), the pressure controller placed in the fuel tank being provided for this purpose.

IGNITION AND INJECTION

The e ngines equipped with UCE injection type SIRIUS 32 are provided with oxygen sensors, as
follows:
-one up stream oxygen sensor – for engines corresponding to EURO 96 de-pollution norms.
- one upstream oxygen sensor and one downstream oxygen sensor – for engine s corresponding
to EURO 2000 de-pollution norms.
OXYGEN SENSORS HEATING
Oxygen sensors heating control is given by UCE injection as follows: -for up stream oxygen sensor – starting with engine starting.
-f or downstream oxygen sensor – after a certain time from engine starting, imposed by the
UCE injection charts, being subject to engine RPM and water temperature, red only when the
accelera tion pedal is not released.
UPSTREAM OXYGEN SENSOR VOLTAGE
After connecting the CLIP tester select “ Injection Diagnostic” and refer to “PR009 parameter:
Upstream oxygen sensor voltage”. The displayed value, expressed in mV, is representing the voltage
supplied towards UCE injection by the oxygen sensor placed upstream as the catalyst. When the
engine is running in the “closed loop” phase, voltage must fluctuate quickly between the following
lim i ts :
-20 mV ± 50 for poor fuel mixture;
-840 mV ± 70 for rich fuel mixture.
Smaller is the difference between these two limits, less good the sensor information is
(g en erally this difference is of 500 mV).
DOWNSTREAM OXYGEN SENSOR VOLTAGE
After connecting the CLIP tester select “ Injection Diagnostic” and refer to “PR010 param-
eter: Downstream oxygen sensor voltage”. The displayed value, expressed in mV, is representing
the voltage supplied towards UCE injection by the oxygen sensor placed after the catalyst. This
sensor has the purpose to catalyst diagnostic and to perform a second checking, more exactly, of
the fuel mixture enriching. This function is becoming active only after a certain time of engine
running at warm and it is not active in the engine idling phase.
When the engine is running in “closed loop” phase and at stabilized speed, voltage must fluctuate
ha ving between the maximal and minimal limits a difference of 600-mV ± 100. At deceleration,
voltage mu st be under 200 mV.

This diagnostic may detect:
-spark plug fouling or smoking,
-fou ling or modification from the normal value of the injectors flow,
-f uel supply system abnormalities (pressure controller, fuel pump,..)
-pr oblems with the electric connections for controlling fuel supply circuits and the injection.
Th e di ag nostic is performed by variations measurement of the engine prompt rotation speed.
Notice of a couple decrease is allowing the defective combustion recognition as failure cause.
Th is diagnostic is done almost permanently during driving. Non accomplishment of the diagnos-
tic or recognition of the existence of failure, is leading to other OBD diagnostics inhibition. This diagnostic is enabling the identification of two types of failures:
-de structive combustion misfires, which are causing the catalyst damage. These are gener-
ating the immediate blinking of the OBD indicator. -Polluting combustion misfires, leading to e xceeding a pre-established OBD pollution limit.
These ar e generating the permanent lighting of the OBD indicator, if the cause detection is
taken place during three consecutive running.
DE T ECT ION CONDITIONS
At the beginning, it must be checked if the “learning” stages of the adaptive values by the UCE
injection have been correctly performed. Also the preliminary conditions imposed when setting the
co ntact on and those from checking moment, must be accomplished.
Check by means of the CLIP tester if the bellow mentioned states are in the following configu-
ration:
ET0 14 Cylinder 1 recognition----------------------------------------------------------------- DONE
ET2 02 OBD diagnostic of combustion misfires taken into consideration--------------AC TIVE
Detection is accomplished after the water temperature is exceeding 75°C, at three rotation
steps, between idling and 4500 rot/min. It is also possible, test performing by maintaining the engine
at idling for a period of time of 11 minutes.
ATTENTION: after performing this test, the contact set ting on is imposed (key in M
position) before reading the r esults by means of the CLI P t ester. Any contact set ting off
be fore reading the test results, will lead to their wrong interpretation.
If after test performing, the CLIP tester is noticing the presence of the combustion mis-
f ires, refer to the diagnostic method related to this symptom.
CONFIRM ATION OF THE RE PARATION PE RFORM ING
-Check by m eans of the CLIP tester, the bellow states, which must have the following
c onfiguration:
ET0 14 Cylinder 1 recognition -------------------------------------------------------------------- DONE
ET2 02 OBD diagnostic of combustion misfires taken into consideration ----------------- AC TIVE
-N o failures is detected by the CLIP tester, and the OBD indicator must be off.

Ensure that all failures are solved. Erase all memorized failures.
There is no need to erase the “adaptive values” memoriz ed by the injection computer.
In order to check the correct reparation of the system, the following conditions must be
AF TER accomplished:
REPARATION - No more electrical failures;
- All “adaptive values” to be memorized by the injection computer;
- Warm engine (minimum 75°C);
- Run at idling, all consumers being in use for 20 minutes (1 minute DF110);
- If the failure is again occurring, repeat the dia gnostic.
