1. DEF: Micro-breaks
2. DEF: Signal inconsistency
NOTESConditions for application to a stored fault:
The fault is declared present after the ignition has been switched on for at least
10 seconds.
If the fault is present:
– the engine overheating warning light is lit on the instrument panel,
– the fan assemblies are running,
– the air conditioning compressor is switched off, the coolant temperature value
switches to safe mode, 10°C < PR064 Coolant Temperature < 90°C.
Use CLIO III, MODUS, MEGANE II ph2, SCENIC II ph2 and KANGOO II Wiring
diagrams Technical Note.
Check the connection and condition of the coolant temperature sensor connector, component code244 (see
MR 392, 385, 364, 370 and 417, Mechanical, 19A, Cooling system, Coolant temperature sensor:
Removal - Refitting) and the injection computer, component code120 (see MR 392, 385, 364, 370 and 417,
Mechanical, 13B, Diesel injection, Diesel injection computer: Removal - Refitting).
If the connectors are faulty and if there is a repair procedure (see Technical Note 6015A, Repairing electrical
wiring, Wiring: Precautions for repair) repair the connector(s); otherwise, replace the wiring.
Measure the resistance of the coolant temperature sensor, component code 244, between connections 3C and
3JK.
If the resistance is not:
11332Ω < X < 13588Ω at - 10°C,
2140Ω < X < 2364Ω at 25°C,
771Ω < X < 849Ω at 50°C,
275Ω < X < 291Ω at 80°C,
replace the coolant temperature sensor (see MR 392, 385, 364, 370 and 417, Mechanical, 19A, Cooling
system, Coolant temperature sensor: Removal - Refitting).
Check the insulation, continuity and the absence of interference resistance on the following connections:
–3C between components 244 and 120.
–3JK between components 244 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 the fault is still present, contact the Techline.
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.

NOTESProcessing priority in the event of a number of faults:
First deal with the fault DF012 Sensor supply voltage no. 2 if the fault is present or
stored.
Conditions for applying the fault finding procedure to a stored fault:
Apply the fault finding procedure below, whether the fault is present or stored.
Use CLIO III, MODUS, MEGANE II ph2, SCENIC II ph2 and KANGOO II Wiring
diagrams Technical Note.
Check the connection and condition of the connector for the refrigerant fluid pressure sensor, component
code1202 (see MR 392, 385, 364, 370 and 417, Mechanical, 62A, Air conditioning, Pressure sensor:
Removal - Refitting).
If the connector is faulty and there is a repair procedure (see Technical Note 6015A, Electrical wiring repair,
Wiring: Precautions for repair), repair the connector, otherwise replace the wiring.
Check the connection and condition of the injection computer connector, component code 120 (see MR 392,
385, 364, 370 and 417, Mechanical, 13B, Diesel injection, Diesel injection computer: Removal - Refitting).
If the connector is faulty and there is a repair procedure (see Technical Note 6015A, Electrical wiring repair,
Wiring: Precautions for repair), repair the connector, otherwise replace the wiring.
With the ignition on, check for the presence of + 5 V on connection 38Y and an earth on connection38U of the
refrigerant fluid pressure sensor.
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.
Check the insulation, continuity and the absence of interference resistance on the following connections:
–38Y between components1202 and 120,
–38X between components1202 and 120,
–38U between components1202 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 the fault is still present, replace the
refrigerant fluid sensor (see MR 392, 385, 364, 370 and 417, Mechanical,
62A, Air conditioning, Pressure sensor: Removal - Refitting).
AFTER REPAIRDeal with any faults displayed by the diagnostic tool.
Clear the computer fault memory.

NOTESConditions for applying the fault finding procedure to a stored fault:
The fault becomes present with the engine running and an air conditioning request.
Order of priority in the event of more than one fault:
Deal with fault DF049 Refrigerant sensor circuit first if it is present or stored.
Use the CLIO III, MODUS, MEGANE II ph2 and SCENIC II ph2 Wiring Diagrams
Technical Note.
When the fault is present or stored, the heating and air conditioning system is inhibited. There is no longer any air
conditioning.
Check the air conditioning fuse and check the air conditioning compressor connector, component code 171.
If the connector is faulty and there is a repair procedure (see Technical Note 6015A, Electrical wiring repair,
Wiring: Precautions for repair), repair the connector, otherwise replace the wiring.
Check the continuity and insulation of the following connections:
– 38R between components 171 and 1337,
– Mbetween the earth and component 171.
If the connection or connections are faulty and there is a repair procedure (see Technical Note 6015A, Electrical
wiring repair, Wiring: Precautions for repair), repair the wiring, otherwise replace it.
Manually check if the compressor is jammed (turn the clutch plate manually to check that there is no point of
resistance).
In the event of jamming, replace the air conditioning compressor (see MR 364 (Mégane II), MR 370 (Scénic II),
MR 385 (Modus), MR 392 (Clio III), Mechanical, 62A, Air conditioning, Compressor:
Removal - Refitting)
Charge the air conditioning circuit, check for any leaks and repair if necessary (see MR 364 (Mégane II), MR 370
(Scénic II), MR 385 (Modus), MR 392 (Clio III), Mechanical, 62A, Air conditioning, Air conditioning: Check
and air conditioning:
Draining - Filling).
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.

AC AUTHORISED
STATUS DEFINITION"YES": This status shows that the air conditioning is authorised.
"NO": This status shows that the air conditioning is not authorised.
NOTESSpecial notes:
Only perform these tests if the status does not correspond with the system
programming functions.
Conformity check: Engine switched off and ignition on or engine running, engine coolant temperature

YES
The air conditioning authorisation only changes to "YES" if:
– the air conditioning request has been made by the driver (air conditioning switch in
AC position with minimum ventilation),

"INACTIVE": The status indicates that the low-speed fan request is not active.
NOTESSpecial notes:
Only perform these tests if the status does not correspond with the system
programming functions.
NOTE:
Status ET022 Low-speed fan request changes status.
Conformity check with engine stopped and ignition on, or engine running, and engine coolant
