3.DEF: Values outside tolerances
NOTESConditions for applying the fault finding procedure to a stored fault:
The fault is declared present after:
– the engine is started,
– a road test,
– actuator command AC012 Damper valve;
– the ignition is switched off for 1 minute.
Special notes:
If the fault is present:
– it is difficult or even impossible to start the vehicle,
– the engine stops noisily,
– the level 1 warning light is illuminated.
Use bornier Elé.1681 or Elé.1590 for any operation on the injection computer
connectors.
Priorities when dealing with a number of faults:
Deal with fault DF046 "Battery voltage" first if it is present or stored.
IMPORTANT
This fault can result in a rapid and significant fouling of the particle filter.
CC.1
NOTESAfter any work is carried out on the damper valve, run SC036
Reinitialise programming and select Damper valve, then
switch off the ignition and wait 1 minute.
Check the damper valve connections.
Check the injection computer connections.
Repair if necessary.
Check the continuity and insulation from + 12 V of the following connections:
– connection code NT (Laguna II) or N (Scénic II and Mégane II) between component 1461 and chassis earth
NT or N.
– connection code 3VN,
– connection code 3VM.
between components 120 and 1461.
If the connection or connections are faulty and 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, replace the damper valve.
AFTER REPAIRDeal with any faults.
Carry out a road test followed by another check with the diagnostic tool.

If the connection or connections are faulty and 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, check that the computer output is working correctly.
Damper valve connected:
– connect the negative terminal of the voltmeter to connection 3VN of the damper valve,
– connect the positive terminal of the voltmeter to connection 3VM of the damper valve,
– use command AC012 Damper valve:
The voltmeter should display ten cycles of two successive voltages: ~2.5V (OCR* of 20%) then ~8.75V (OCR*
of 70%).
If the voltmeter does not indicate any control while the command is running (ten 1-second cycles), contact the
Techline.
AFTER REPAIRDeal with any faults.
Carry out a road test followed by another check with the diagnostic tool.
