If DF130, the engine may stop with the level 1 and 2 warning lights illuminated along
with the message Faulty injection.
Conditions for applying fault finding procedures to stored faults:
The fault is present with the engine running.
Check the connection and condition of the of the fuel flow actuator connector (IMV), and repair it if necessary.
Measure the resistance between tracks 1 and 2 of the flow actuator.
Replace the flow actuator if the resistance is not 5.3 Ω ± 0.5 Ω at 20°C.
Check the connection and condition of the computer 48-track brown connector B.
Repair if necessary.
Check the insulation, continuity and the absence of interference resistance on the following connection:
Computer connector B track M4 track 1 fuel flow actuator
Repair if necessary.
Check that there is fuel present in the tank and that it is correct. Run Test 13 Diesel fuel conformity check.
Run Test 1 Low pressure circuit check.
Run Test 6 High pressure system check.
Repair if necessary.

1.DEF: Jammed component
NOTESConditions for applying fault finding procedures to stored faults:
The fault is declared present with the engine running and with a climate control 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. There is no longer any air
conditioning.
Check fuse F22 (10 A) of the UPC, component code 1337.
Check the connector of the air conditioning compressor, component code 171.
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 wiring of the air conditioning compressor.
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 jamming, replace the air conditioning compressor (see MR 364 (Mégane II), MR 370
(Scénic II), Mechanical, 62A, Air conditioning, Compressor: Removal - Refitting).
Top up the refrigerant, check for any leaks, and repair if necessary (see MR 364 (Mégane II), MR 370 (Scénic II),
Mechanical, 62A, Air conditioning, Refrigerant circuit: Draining - Filling).
