NOTESConditions for applying the fault finding procedure to a stored fault:
The fault is declared present after:
– with the engine running,
– the battery voltage X > 8V.
Priorities when dealing with a number of faults:
– DF038 Computer,
– DF323 Damper valve,
– DF012 Sensor supply voltage no. 2,
– DF646 Damper valve position sensor.
Special notes:
If the fault is present:
–the level 1 warning light is lit (for Vdiag 20, 58, 24, 5C, 26, 28, 60 and 62),
– particle filter regeneration is inhibited.
Use bornier Elé. 1681 for all operations on the engine management computer
connector.
Use the Wiring Diagram Technical Note, Laguna II ph2, Vel Satis ph2, Espace IV
ph2, Mégane II ph2, Scénic II ph2.
Check the condition and connection of the damper valve connector (see Wiring Diagram Technical Note,
Laguna II ph2, Vel Satis ph2, Espace IV ph2, Mégane II ph2, Scénic II ph2, component code 1461).
Check the condition and connection 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 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.
