REQUEST TO START COMPRESSOR
STATUS DEFINITION"ACTIVE": This status indicates that the compressor activation request is active.
"INACTIVE": This status indicates that the compressor activation request is not active.
NOTESSpecial notes:
Only perform these tests if the status does not correspond with the system
programming functions.
Conformity check with engine stopped and ignition on, or engine running, and engine coolant temperature
>80 °C
ACTIVE
Status ET088 becomes ACTIVE if there has been a request for air conditioning (press
on AC or AUTO button, with maximum cold request) and status ET004 is YES.
The selection is made on the air conditioning control panel, the request for air
conditioning is transmitted to the UCH which in turn transmits the request to the
injection computer which either authorises or does not authorise compressor activation.
If the injection computer authorises compressor switch-on, the injection computer
sends the compressor switch-on request to the UPC and status ET088 becomes
""ACTIVE" (Climate control).
If the vehicle is equipped with manual air conditioning, the air conditioning request is
transmitted from the air conditioning control panel to the UCH which then accepts or
does not accept the air conditioning compressor coming on depending on the operating
status of the passenger compartment fan. When the request has been accepted, the
request to switch on the compressor is transmitted to the injection computer which
either authorises or does not authorise the compressor to start.
If the injection computer authorises compressor switch-on, it sends the request for
compressor switch-on to the UPC and status ET088 becomes "ACTIVE".
If there has been no compressor switch-on request and status ET088 remains
"ACTIVE", see62A, Air conditioning.
Note: Compressor operation is only authorised when the engine is running.
Compressor activation is commanded by the UPC.
AFTER REPAIRCarry out a road test, then check with the diagnostic tool.

PREHEATING RELAY CONTROL
STATUS DEFINITION"ACTIVE": This status indicates that the preheating relay control is active.
"INACTIVE": This status indicates that the preheating relay control is not active.
NOTESSpecial notes:
Only perform these tests if the status does not correspond with the system
programming functions.
Conformity check with engine stopped and ignition on, or engine running, and engine coolant temperature
>80 °C
ACTIVE
The status is "ACTIVE" from when the ignition is switched on until the end of pre-
postheating.
The preheating duration varies according to:
●The engine coolant temperature,
●The atmospheric pressure
●The battery voltage.
If the status is inconsistent, consult the interpretation of fault DF017 "Preheating unit
control circuit".
INACTIVEThe status is "INACTIVE" when the engine is started and the engine coolant
temperature is more than 80 °C.
If the status is inconsistent, consult the interpretation of fault DF017 "Preheating unit
control circuit".
AFTER REPAIRCarry out a road test, then check with the diagnostic tool.

SYNCHRONISATION
STATUS DEFINITIONNOT DONE: This status indicates that synchronisation has not been carried out.
DONE: This status indicates that synchronisation has been carried out.
NOTESSpecial notes:
Only perform these tests if the status does not correspond with the system
programming functions.
WARNING
Synchronisation is carried out during the engine starting phase. This is established between the camshaft position
sensor and the TDC sensor.
Once this synchronisation has been carried out, it enables the computer to identify cylinder no. 1 and to calculate
the precise position of the cylinder's Top Dead Centre.
Conformity check with the engine stopped and the ignition on, or engine running, and engine coolant
temperature > 80°C
NOT PERFORMED
When the engine is switched off but the ignition switched on, cylinder no.1 is no longer
indicated.
Status ET238 is NOT DONE: synchronisation between the crankshaft and the camshaft
has not been carried out.
COMPLETEDSynchronisation is carried out during the engine starting phase.
Cylinder No. 1 is indicated and synchronisation will be performed once the engine is
started.
If, after several attempts to start the engine, status ET238 remains NOT DONE, refer to
the interpretation of the following faults:
– DF005 Engine speed sensor circuit.
– DF097 Camshaft sensor circuit.
If the engine still does not start, consult ALP2 The engine does not start or starts
with difficulty.
AFTER REPAIRCarry out a road test, then check with the diagnostic tool.

RAIL PRESSURE
PARAMETER
DEFINITIONThis parameter indicates the fuel pressure in the rail in bars.
NOTESThere must be no present or stored faults.
Perform this fault finding procedure:
– after an inconsistency appears on the Parameter screen,
– following the activation of command AC003 Fuel pressure solenoid valve,
– following a customer complaint (starting problems, poor performance, stalling, etc.).
Use CLIO III, MODUS, MEGANE II ph2, SCENIC II ph2 and KANGOO II Wiring
Diagrams Technical Notes.
Conformity check with the engine stopped and the ignition on, or the engine running and the engine
coolant temperature > 80°C
Check the insulation, continuity and the absence of interference resistance on the following connections:
–3LX between components 1032 and 120,
–3LY between components 1032 and 120,
–3LZ between components 1032 and 120.
If the connection(s) are faulty and there is a repair method (see Technical Note 6015A, Repairing electrical
wiring, Wiring: Precautions for repair), repair the wiring, otherwise replace it.
If all these connections are correct, check for the fuel pressure sensor supply:
+ 5 V on connection code 3LX between components 1032 and 120,
Earth on connection code 3LZ between components 1032 and 120.
If the connection(s) are faulty and there is a repair procedure (see Technical Note 6015A, Repairing electrical
wiring, Wiring: Precautions for repair), repair the wiring, otherwise replace it.
Check the low and high pressure diesel circuit sealing (visual checks, odours): on pump body, pressure release
valve, pipes, rail and injector unions, injector wells, etc.
If all the above checks are correct:
With the vehicle ignition on, and engine stopped for over 1 minute:
Display PR038; if the value is lower than 30 bar, the sensor is correct.
Otherwise replace the rail pressure sensor (see MR 392, 385, 364, 370
and 417 Mechanical, 13B, Diesel
injection, Rail pressure sensor: Removal - Refitting).
AFTER REPAIRDeal with any faults displayed by the diagnostic tool.
Clear the computer memory.
Carry out a road test followed by another check with the diagnostic tool.

SC017
CONTINUED
After-Sales regeneration comprises 4 important stages:
– Heating of the engine and checking for a small quantity of soot in the particle filter by measuring the differential
pressure.
– The system changes from combustion mode and starts to regenerate the particle filter. Gradual cooling of the
particle filter.
– End of After-Sales regeneration.
Stopping conditions:
– Dialogue with the diagnostic tool has been lost.
– Vehicle movement detected by speed sensor.
– Brake or clutch pedal depressed.
– Stop regeneration requested by the diagnostic tool.
– End of test.
The procedure lasts 30 minutes.
– At the end of regeneration, a message announces whether the regeneration has been successful or which
operations to carry out.
CONFIRMING THE REGENERATION PROCESS:
At the end of regeneration, a message appears to announce whether the regeneration was successful:
particle filter regeneration successful: regeneration completed correctly.
weight of soot too high - run command SC017 again: regeneration failed because the weight of soot at
the end of regeneration was too high and the temperature upstream of the particle filter was too low. Check
the oil level before starting another regeneration.
weight of soot too high: regeneration failed because the weight of soot at the end of regeneration was
too high in spite of the correct temperature upstream of the particle filter. The particle filter is full of residue
(regeneration impossible), refer to the fault finding chart ALP21 Particle filter warning light lit.
present or stored fault: regeneration failed because faults were declared.
Refer to the interpretation of faults, after resolving the faults, run command SC017 again.
AFTER REPAIRDeal with any faults displayed by the diagnostic tool.
Clear the computer fault memory.
Carry out a road test followed by another check with the diagnostic tool
