NOTESConditions for applying fault finding procedures to stored faults:
The fault becomes present if:
– ignition is on (CC.0),
– following a road test, engine warm (CO.1).
IMPORTANT:
The particle filter downstream temperature sensor only measures temperatures
greater than 50°C.
Special notes:
– If the fault is present:
– After-Sales particle filter regeneration is inhibited,
– particle filter fault finding is inhibited (for Vdiags 18, 1C and 54).

Check the condition of the engine management computer connector (see Wiring Diagram Technical Note,
Laguna II ph2, Vel Satis ph2, Espace IV ph2, 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 from earth of the following connections:
•3TG between components 120 and 1288,
