2.DEFNOTESThe fault is declared present or stored after an attempt to
start or after starting, with the engine cold, several hours
after the last trip (the difference in the coolant temperature
from the last engine stop and the present attempt to start
must be at least 60°C).
The level 1 warning light is on.
Check the condition of the rail pressure sensor connector (see Wiring Diagram Technical Note, Mégane II ph2,
Scénic II ph2, component code 1032).
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 that there are no external diesel leaks from the high pressure fuel circuit.
Check the continuity and for the absence of interference resistance on the following connections:
– connection code 3LZ between components 120 and 1032,
– connection code 3LX between components 120 and 1032,
– connection code 3LY between components 120 and 1032.
If there is a repair method (see Technical Note 6015A, Repairing electrical wiring, Wiring: Precautions for
repair), repair the wiring, otherwise replace it.
With the ignition on and the engine stopped for over 1 minute:
View parameter PR038 Rail pressure.
– If the pressure is below 90 bar, the sensor is in order.
– If the pressure is above 90 bar, contact the Techline.
If the fault is still present, contact the Techline.
AFTER REPAIRDeal with any other faults. Clear the fault memory.
Switch off the ignition until the end of the power-latch phase, and carry out a road test
followed by a check using the diagnostic tool.

NOTESConditions for applying the fault finding procedure to stored faults:
– The fault is declared present after:
– the ignition is switched on,
– starting the engine,
– a road test.
Special notes:
If the fault is present,
– thermoplunger cut-off,
– engine torque limited,
– the cruise control/speed limiter function is switched off,
– the EGR function is inhibited by the engine management computer,
– safe mode on the pedal sensor: use the value of gang 2 instead of gang 1.
The level 1 and European On Board Diagnostic warning lights are illuminated.
Use bornier Elé. 1681 for all operations on the connectors of the engine management
computer.
Use Wiring Diagram Technical Note, Mégane II ph2, Scénic II ph2.

If there is a repair method (see Technical Note 6015A, Repairing electrical wiring, Wiring: Precautions for
repair), repair the wiring, otherwise replace it.
Clear the faults created by the multiple disconnections.
Carefully examine the engine management computer connections (for conductive particles, bent pins).
If the fault is still present, contact the Techline.
AFTER REPAIRDeal with any other faults. Clear the fault memory.
