NOTESConditions for applying the fault finding procedure to a stored fault:
The fault is declared present after several attempts to start the engine or after running
actuator command AC001 Preheating unit.
Special notes:
If the fault is present, it is difficult or even impossible to start the vehicle when cold.
If the fault is present, the level 1 warning light is lit.
Use bornier Elé.1681 or Elé.1590 for any operation on the injection computer
connectors.
CC.1
NOTESNone
Check the pre-postheating unit connections and the heating plug supply cables.
Check the injection computer connections.
Repair if necessary.

NOTESConditions for applying the fault finding procedure to a stored fault:
The fault is declared present with the engine running and a heating and air
conditioning request
Priorities when dealing with a number of faults:
Firstly, deal with the following faults:
–DF049 Refrigerant sensor circuit, if it is present or stored.
When the fault is present or stored, the heating and air conditioning system is inhibited.
Check fuse F22 (10A) of the UPC and the condition of the air conditioning compressor connector.
If the connectors 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 air conditioning compressor wiring.
If the wiring is faulty and there is a repair procedure (see Technical Note 6015A, Repairing electrical wiring,
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 sticking, replace the air conditioning compressor (see MR 364 (Mégane II) or 370
(Scénic II), Mechanical, Heating and air conditioning system, 62A, Air conditioning, Compressor:
Removal – Refitting).
Top up with refrigerant, check for any leaks and repair if necessary (see MR 364 (Mégane II) or 370 (Scénic II),
Mechanical, Heating and air conditioning system, 62A, Air conditioning, Refrigerant circuit: check,
Refrigerant circuit: Draining – Filling).
AFTER REPAIRDeal with any faults.
Carry out a road test followed by another check with the diagnostic tool.
