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(s) is/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 to earth of the following connections:
– connection code 3LX between components 120 and 1032,
– connection code 3LY between components 120 and 1032.
Check the continuity of the following connection:
– connection code 3LZ 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.
If the wiring of the particle filter downstream temperature sensor, component code 1288, is present (with or without
the sensor being present), check the electrical insulation in relation to + 12 V between the following connections:
•3XU between components 120 and 1288,
•3TG between components 120 and 1288.
If the connection or connections are faulty and there is a repair procedure (see Technical Note 6015A, Electrical
wiring repair, Wiring: Precautions for repair), repair the wiring, otherwise replace it.
If the fault is still present, replace the turbocharger pressure sensor.
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.

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.
