NOTESSpecial notes:
This fault appears when the computer control section has
overheated.
– A road test may be necessary.
Priority when dealing with a number of faults:
Deal with the statuses CO, CC.0, and CC.1 first if they are
present or stored.
After any operation on the damper valve, run SC036
Reinitialise programming (see Interpretation of
commands).
Check the condition of the damper valve connector (see Wiring Diagram Technical Note, Mégane II ph2,
Scénic II ph2, component code 1461).
Check the condition of the engine management computer connector (see Wiring Diagram Technical Note,
Mégane II ph2, Scénic II ph2, component code 120).
If the connectors are faulty and if there is a repair procedure (see Technical Note 6015A, Repairing electrical
wiring, Wiring: Precautions for repair), repair the connector, otherwise replace the wiring.
Check that the valve is not mechanically jammed:
With the engine stopped, disconnect the air inlet hose from the damper valve.
Check that the valve is in the open position.
Start, then switch off the engine.
Check that the valve closes when the engine is switched off and then opens again when the engine has stopped.
If this does not happen, replace the damper valve.
Check that the valve is clean and that there is no component preventing it from closing (particularly for 2.DEF).
Clean if necessary.
Check the continuity of the following connections:
– Connection code 3VM between components 1461 and 120.
– Connection code 3VN between components 1461 and 120.
Check the insulation against + 5 V and + 12 V (computer feed) of the following connections:
– Connection code 3VM between components 1461 and 120.
– Connection code 3VN between components 1461 and 120.
If there is a repair method (see Technical Note 6015A, Repairing electrical wiring, Wiring: Precautions for
repair), repair the wiring, otherwise replace it.
If the fault is still present, contact the Techline.

Check the condition of the engine management computer connector (see Wiring Diagram Technical Note,
Mégane II ph2, Scénic II ph2, component code 120).
If the connector or connectors are faulty and if there is a repair procedure (see Technical Note 6015A, Repairing
electrical wiring, Wiring: Precautions for repair), repair the connector, otherwise replace the wiring.
Check the insulation, continuity and the absence of interference resistance on the following connections:
– connection codes 38U, 38X, 38Y between components 1202 and 120.
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.
If the wiring of the particle filter downstream temperature sensor, component code 1288, is present (with or without
the sensor being present), check the electrical insulation in relation to + 12 V between the following connections:
•3XU between components 120 and 1288,
•3TG between components 120 and 1288.
If the connection or connections are faulty and there is a repair procedure (see Technical Note 6015A, Electrical
