NOTESConditions for applying the fault finding procedure to a stored fault:
The fault is declared present during an After-Sales regeneration, if the temperature
threshold is exceeded.
Special notes:
If the fault is present:
– regeneration in progress is stopped.
IMPORTANT: The fault appears if the temperature threshold is exceeded during
the After-Sales regeneration phase.
• Carry out particle filter replacement
• run command SC036 Reinitialise programming (see Interpretation of commands) and select After particle
filter replacement.
•switch off the ignition and wait for the diagnostic tool message (maximum wait 8 minutes): Loss of
dialogue with the computer: EDC16 CP33, check the tool connection and the computer supply voltage,
• then switch on the ignition again,
•clear the present or stored faults from the computer memory (operation to be carried out within 3 minutes
of switching on the ignition).
If the fault is still present, contact the Techline.

– an engine speed below 1500 rpm.
The level 1 warning light is illuminated.
Conditions under which the fault appears:
This fault only appears when the computer is reprogrammed after a change of Vdiag.
If the fault is present, display status ET781 Heater plugs in the sub-function Ignition/Preheating.
If status ET781 is STATUS 3, this means that the heater plugs are not configured in the injection computer.
To find out which type of heater plugs are fitted to the engine, look at the colour of the rings on the plugs.
– Slow plugs have a black ring.
– Fast plugs have a white ring.
To configure the type of plugs, run command SC036 Reinitialise programming and select HEATER PLUGS (see
Interpretation of commands).
If the fault is stored, clear the fault.
End of fault finding.
If the fault is still present or if status ET781 is not STATUS 3 or is inconsistent with the type of plug fitted, contact

If the ignition is not switched on, status ET001 should be ABSENT.
As soon as the ignition is switched on, the computer should be supplied with power. Status ET001 becomes
PRESENT.
If this status remains locked on ABSENT, follow the procedure below:
– Check the condition of fuse FM3 (30A) in the engine fuse and relay box (see MR 395 (Laguna II ph2), 405
(Espace IV ph2) Mechanical, 81C, Fuses, Fuses: List and location of components).

MR370 (Scénic II ph2) Mechanical, 81C, Fuses, Fuses: List and location of components).
Check the continuity and absence of interference resistance on the following connection:
•3AA between components 120 and 983 or 1337.
If the connection is faulty and there is a repair procedure (see Technical Note 6015A, Electrical wiring repair,
Wiring: Precautions for repair), repair the wiring, otherwise replace it.
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 is faulty and there is a repair method (see Technical Note 6015A, Repairing electrical wiring,

YES
When the driver depresses the clutch pedal, status ET034 becomes YES until
the ignition is next switched off.
If NO appears despite the clutch pedal being depressed, carry out the following
operations:
– Remove the clutch pedal switch, check the insulation between connections M
and86D of component 675, with the switch in the rest position.
– Repeat this operation with the switch engaged and check the continuity
between the two connections.
If these 2 checks are faulty, replace the switch.

component code 675).
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
(seeTechnical Note 6015A, Repairing electrical wiring, Wiring: Precautions
for repair), repair the connector, otherwise replace the wiring.
Then check the continuity and absence of interference resistance of the
