OR
STOREDCOLD LOOP
NOTESConditions for applying the fault finding procedure to a stored fault:
The fault is declared present with the engine running and with a heating and air
conditioning system request.
Priorities when dealing with a number of 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 connector is faulty and there is a repair method (see Technical Note 6015A, Repairing electrical wiring,
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 the wiring.
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 the 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.
