NOTESNone.
Check the EGR valve connections.
Check the injection computer connections.
Repair if necessary.
Check the resistance of the EGR solenoid valve between tracks 1 and 5.
If the resistance is not approximately 8 Ω ±0.5 at 20°C, replace the EGR valve.
Check for continuity, insulation and the absence of interference resistance on the following connections:
Injection computer brown 48-track connector B, track L2 Track 5 of the EGR valve
UPC PPM1 black connector track 1 Track 1 of the EGR valve
Check for + 12 V after relay (UPC) on track 1 of the EGR valve.
Repair if necessary.
If the fault persists, check that the computer output stage is working correctly:
– Run actuator command AC002 EGR solenoid valve.
– If there is no perceptible movement of the valve, ensure that the computer output is functioning:
– Leave the EGR valve connected.
– Connect a "wire clip" to the violet wire between the valve and the injection computer (connection
between track 6 of the valve and track J2 of the injection computer connector B).
– Connect the positive terminal of the voltmeter to the wire clip.
– Connect the negative terminal of the voltmeter to the battery earth.
– Run command AC002 EGR solenoid valve.
– The voltage should vary over 10 cycles between 1.05 V and 3.5 V.
– If the voltage varies between these values, replace the EGR valve.
– If the voltage does not vary or varies between incorrect values, contact the Techline.
AFTER REPAIRDeal with any faults.
Carry out a road test, then check with the diagnostic tool.

NOTESConditions for applying the fault finding procedure to stored faults:
The fault is declared present after:
– replacing injector(s),
– replacing the injection computer.
Special notes:
If the fault is present:
– the engine speed is limited,
– the level 1 warning light is lit.
1.DEF
NOTESNone.

the engine will operate in defect mode.
– Program the injector codes using:
command SC002 Enter injector codes, (follow the procedure described in the Interpretation of commands
section).
– After the codes have been entered:
– switch off the ignition,
– wait until power latch closes down and then switch the ignition back on,
– establish dialogue and clear the fault memory,
– end of operation.
If the fault is still present, contact the Techline.
AFTER REPAIRDeal with any faults.
Carry out a road test, then check with the diagnostic tool.

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 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 with freon, 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, then check with the diagnostic tool.
