POWER ABSORBED BY THE AIR CONDITIONING COMPRESSOR*
PARAMETER
DEFINITIONThis parameter indicates the power absorbed by the air conditioning compressor in W.
NOTESSpecial notes:
Only perform these tests if the parameters do not correspond with the system
operation programming.
For Kangoo II only
Conformity check with the engine stopped and the ignition on, or with the engine running without electrical
consumers, and engine coolant temperature > 80°C
PR125= 0W
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.

SC001
WRITE SAVED DATA
NOTESTo be able to run this command, it is essential to save the data using command SC003
Save computer data.
Writing is carried out after the computer has been reprogrammed or replaced.
Validating this command writes the data saved using command SC003 Save computer data.
The data is as follows:
– vehicle idle speed,
– programming of exhaust gas recirculation valve data,
– options available on the vehicle and managed by the computer (Example: Air conditioning),
– data specific to injection and particle filter operation.
The data configures the computer and prevents:
– engine malfunction after reprogramming or replacing the computer,
– incorrect interpretation of the information provided by the CLIP diagnostic tool.
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.

SC003
SAVE COMPUTER DATA
NOTESThis save is carried out before computer reprogramming or replacement.
On the CLIP tool, select the SC003 Save computer data.
If the following message appears:
"a saved file exists, do you want to overwrite this data?":
(this file corresponds to the last save made on the CLIP diagnostic tool)
select "YES".
Confirming this command saves the following vehicle-specific data:
– the egr valve data programming;
– options available on the vehicle and managed by the computer (e.g. air conditioning);
– data specific to injection and particle filter operation.
This information will be saved in the CLIP diagnostic tool.
When saving is finished, run command SC001 Write saved data in order to configure the new computer after
programming or reprogramming.
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.

ALP 6 Engine idle speed too low or unstable
NOTESOnly address this customer complaint after a complete check with the diagnostic
tool.
Check the presence and conformity of the fuel by running Test 13 Diesel fuel conformity check.
Check the injection computer: that the connections and wiring are in good condition, that earths and feeds are
present.
If the wiring is faulty and there is a repair method (see Technical Note 6015A, Repairing electrical wiring,
Wiring: Precautions for repair), repair the wiring, otherwise replace the wiring.
Check the air inlet circuit (refer to the interpretation of fault DF301 Air inlet circuit).
Check that the damper valve operates correctly (refer to the interpretation of fault DF641 Damper valve circuit).
Check the air flowmeter (refer to the interpretation of faults DF039 Inlet air temperature sensor circuit, DF129
Air flow requested and DF056 Air flow sensor circuit).
Check the air conditioning pressure sensor (refer to the interpretation of fault DF049 Refrigerant sensor circuit).
If the wiring is faulty and there is a repair method (see Technical Note 6015A, Repairing electrical wiring,
Wiring: Precautions for repair), repair the wiring, otherwise replace the wiring.
If fault DF308 Particle filter clogged is present, replace the particle filter.
Run command RZ030 Particle filter adaptives after replacing the particle filter.
Check the low pressure fuel supply system by performing test 1 Low pressure supply check and test 2
Internal fuel transfer pump (ITP) check.
Check the high pressure fuel supply system by performing test 3 High pressure fuel pressure solenoid valve
check, test 4 High pressure pump (HPP) and fuel flow solenoid valve check and test 5 Rail high pressure
regulation circuit check.
Check the injectors by performing test 6 Major injector leak/injectors open and test 7 Incorrect injection
amount.
AFTER REPAIRCarry out a road test followed by a complete check with the diagnostic tool.

TEST 5 Rail high pressure control circuit check
NOTESConditions prior to test:
Engine temperature between 80°C and 90°C.
All the electrical consumers are switched off.
Air conditioning is switched off.
The tank is at least half-full.
The pipe connections and unions have been checked.
Check the sealing of the high pressure pipes and unions.
Note:
Routine SC017 Regenerate particle filter cannot be performed while command
AC029 High pressure circuit sealing test is active.
Causes:
Rail pressure variations around the reference value.
The rail reference pressure is not reached.
Rough idle.
Possibly noisy combustion.
Use CLIO III, MODUS, MEGANE II ph2, SCENIC II ph2 and Kangoo II Wiring
diagrams Technical Note.
Start the engine and let it idle.
Are there large air bubbles in the transparent
supply pipe leading to the pump?
NO
Remove the fuel flow solenoid valve connector
(orange), does the engine stop?
YES
YESCheck the low pressure system.
NOReplace the pump (the fuel flow solenoid
valve remains open mechanically).
AFTER REPAIRCarry out a road test followed by a complete check with the diagnostic tool.

TEST 7 Incorrect injection quantity
NOTESConditions prior to test:
The entire low pressure system must be in good condition.
Check the sealing of the high pressure pipes and unions.
Te s t 3 High pressure fuel pressure solenoid valve check is OK.
Test 4 High pressure pump (HPP) and fuel flow solenoid valve check is OK.
Te s t 5 Rail high pressure regulation circuit check is OK.
All the electrical consumers are switched off.
Air conditioning is switched off.
Cause:
The engine runs poorly at idle speed, possibly emits white smoke.
Use CLIO III, MODUS, MEGANE II ph2, SCENIC II ph2 and KANGOO II Wiring
diagrams Technical Note.
Ignition off.
Measure the resistance at the injectors.
The reference resistance is between 150 and
250 kΩ.
Measure at ambient temperature (approx. 20°C),
allow the engine to cool down for at least
30 minutes.
Are the resistances correct?
YES
NOReplace the corresponding injectors.
AFTER REPAIRCarry out a road test followed by a complete check with the diagnostic tool.
