NOTESConditions for applying the fault finding procedure to a stored fault:
The fault becomes present after starting the engine.
If the fault is present:
CC.0: The water heater interface unit is permanently actuated.
CC.1: The water heater interface unit is not actuated.
The level 1 fault warning light is lit on the instrument panel.
Use CLIO III, MODUS, MEGANE II ph2, SCENIC II ph2 and Kangoo II Wiring
diagrams Technical Note.
Check the connection and condition of the thermoplunger unit connector, component code 1550 (see MR 392,
385, 364, 370 and 417, Mechanical, 61A, Heating system, Heating system: List and location of
components).
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 + 12 V on connections BP35 and BP36 of the thermoplunger, component code
1550.
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 continuity, insulation and the absence of interference resistance on the following connection:
–3JA between components 1550 and 120.
If the connection is faulty and there is a repair procedure (see Technical Note 6015A, Electrical wiring repair,
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.

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.

STATUS DEFINITION"ACTIVE": The status indicates that the high-speed fan request is active.
"INACTIVE": The status indicates that the high-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 ET021 "High-speed fan request" changes status simultaneously.
Conformity check with engine stopped and ignition on, or engine running, and engine coolant temperature
>80 °C
ACTIVE
The injection computer requests the activation of the high speed GMV when:
– the engine coolant temperature is above 104 °C.
– the injection computer has system faults that could lead to the engine
overheating.
When the high speed fan is supplied:
status ET021 High speed fan request becomes ACTIVE.
INACTIVEThe high-speed engine fan assembly stops when:
– the engine coolant temperature is below 102 °C;

INACTIVE
Status ET088 is "INACTIVE" when no air conditioning request has been made. When
compressor switch-on has not been authorised (ET004 "AC authorised" is "NO") or
when the driver switches the heating and air conditioning system off.
If there is a compressor switch-on request and status ET088 remains "INACTIVE",
see62A, Air conditioning.
Note: Compressor operation is only authorised when the engine is running.
Compressor activation is commanded by the UPC.
