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.

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.

ENRICHING CORRECTION
After connecting the CLIP tester, select “Injection diagnostic” and refer to “PR035 parameter:
En riching correction value”. The value displayed is representing the corrections average imposed
by the UCE injection, subject to the fuel mixture enriching, red by the upstream oxygen sensor (the
sensor is analyzing the oxygen concentration from the exhaust gases). The co rrection value has an average value of 128 and the limits are 0 and 255:
-a value lower than 128 has as result, the request for fuel mixture impoverishment
-a value greater than 128 have as results the request for fuel mixture enriching.
ENRI CHING ADJUSTMEN T PHASE
Admission in the enriching adjustment phase is becoming effective after a certain time from
en gine starting, with the condition that water temperature is reaching to over 22°C and 28 seconds
from engine star ting have passed.
If ad m ission in the enriching adjustment phase is not effective, the value of PR035 parameter is
128.
Even when conditions for enriching adjustment phase beginning are accomplished, UCE injec-
tion however, will not take into account the voltage supplied by the downstream oxygen sensor, in
the following situations: -acceleration pedal fully pressed: PR035 is variable and higher than 128;
-sudden ac celeration: PR035 is variable and higher than 128;
-d ecelera tion (engine braking) followed by UCE injection detection of the position ”free” of
the acceleration pedal: PR035 = 128; -down stream oxygen sensor failure: PR035 = 128.
WORKING PROCEDURE “DAMAGED” IN CASE OF DOWNSTREAM OXYGEN SENSOR FAILURE
When the voltage supplied towards UCE injection by the downstream oxygen sensor is not
correct (showing small or not at all variations) in the enriching adjustment phase, then UCE injec-
tion will not pass to the working procedure “damaged” (PR035 = 128) unless the failure has been
rec ognized as being present for 10 seconds. Only in these conditions, the failure will be memorized
by the UCE injection.
If UC E injection is detecting a present failure of the oxygen sensor and if this failure has been
al rea dy memorized, then UCE injection will come out from the enriching adjustment phase, passing
to phase “open loop”. In this situation PR035 parameter will not show variations and will have the
value 128.

17. The procedure is finished. Check the engine starting with both keys.
REMARK:
For the RF remote control synchronisation, after the replacement of a kit, take into account
the following situations:
- for the first RF remote control, perform the “ SIMPLE SYNCHRONISED PROCEDURE”;
- for t he second RF re m ote control pe rform the “SPE CIFIC SYNCHRONISE D
PROCEDURE”. C. CODE REPAIRING INTRODUCTION PROCEDURE
The repairing code may be introduced only by means of the CLIP tester. This is possible only
if when setting the contact on, the anti starting indicator blinks rapidly, this being confirmed by the
state:
10G ANTI STARTING ……………………………………………….ACTIVE
After getting from DACIA database the repairing code (based on the vehicle chassis series
and on the code from the vehicle’s key head), perform the following operations.
1. Connect the CLIP tester to the diagnostic socket and to the battery (or to the lighter
socket) of the vehicle.
2. The anti start up indicator must blink slowly , the contact being taken off.
3. Set the contact in “M” position. The indicator must blink rapidly.
4. Select vehicle type “B41”;
5. Select the menu “ COMPUTER TEST” then select “ ANTI STARTING”.
6. In the menu “STAT E LIST” find the state 10G “ANTI STARTING” which must be
“ACTIVE”. 7. Access “COMMAND MODE” then select “ACTUATORS”.
8. Select the command “ MANUAL CODE INTRODUCTION” where you will write the
repairi ng c ode (form ed of 4 fi gures), then validate it with t he ke y “ ENTER”. The message
“COMMAND IN PROGRESS” will be displayed followed by the message “FINISHED
COMMAND”. 9. Now the procedure is finished and you may start the vehicle engine.
AT T E N T I ON!
Yo u may perform three attempts of introducing the repairing code; if after the third
essay the code is not yet valid, wait for 15 minutes, take off the contact and then set it
again, then other three attempts may be performed.
REMARK:
This procedure does not decode the injection computer, but is only allowing the start
of the vehicle’s engine. After 10 minutes have passed from the first introduction of the
r epairing code or after the disconnection of the battery, the vehicle’s engine cannot be
s tarted unless a new repairing code is introduced.
