Temperature warning light/red EMERGENCY STOP (level 2)
This indicator light is used both as an in-operation indicator light and as a system fault warning light. It lights up for
3 seconds after the ignition is switched on (automatic test procedure managed by the instrument panel):
– Continuously or intermittently lit, accompanied by the message Engine overheating:
Indicates engine overheating (the driver is free to choose whether or not to stop the vehicle).
–For Vdiag 50, 58 and 5C: continuously lit, accompanied by the message faulty injection:
Indicates a level 2 fault (in this case, the injection is automatically cut after a few seconds).
The driver should carry out repairs as soon as possible.
–For Vdiag 18, 1C and 20: continuously lit, accompanied by the message Injection fault: stop the engine and by
a bleep, this indicates a level 2 fault.
In that case, the vehicle must be stopped immediately (when traffic conditions allow).
The driver should carry out repairs as soon as possible.
ORANGE OBD excess pollution warning light
An engine symbol accompanied by the message Check emission control.
This warning light comes on if the system has one or more OBD faults.
This warning light is used to alert the driver of any injection faults that could lead to excessive pollution, or if the
EOBD system has been deactivated.
The injection computer requests illumination of the OBD warning light for a present fault only after three consecutive
driving cycles.
If it flashes, reduce the engine speed until the flashing stops.
The driver should carry out repairs as soon as possible.
The 3 second visual inspection when the ignition is switched on (automatic test procedure managed by the
instrument panel) is carried out by the injection computer.
Special particle filter ORANGE warning light or warning message (depending on instrument panel)
– Vdiag 50, 58, 5C:
This warning light or message is used to warn the driver that the particle filter is clogged or a significant number of
failed regenerations while driving due to driving conditions not being favourable for regeneration.

NOTESConditions for applying the fault finding procedure to a stored fault:
The fault is declared present after the engine is started or following a road test.
A drop in engine speed followed by nominal behaviour from the vehicle is possible.
Special notes:
If this fault is present:
– It is impossible to start the vehicle,
– the level 1 warning light is illuminated.
Use bornier Elé.1681 or Elé.1590 for any operation on the injection computer
connectors.

NOTESCheck the conformity of the + 12 V after relay supply line,
from connection 3FB (Mégane II and Laguna II) or 3FB1
(Scénic II) of component 1337 or 597.
Use the vehicle Wiring Diagrams Technical Note.
Check the camshaft sensor connections.
Check the injection computer connections.
Check the camshaft sensor fitting and positioning,
Also check its general condition, (damaged housing, overheating, etc.),
Carry out the necessary repairs.
Check the continuity and absence of interference resistance of the following connections:
– connection codes 3CQ and 3FJ between components 120 and 746.
With the ignition on and the camshaft sensor connected:
Use a voltmeter to measure the voltage between connections 3FJ and 3FB (Mégane II and Laguna II) or 3FB1
(Scénic II) of the camshaft sensor:
The voltage displayed should be equal to the battery voltage ± 0.08 V.
– If the voltage is outside permitted tolerance values, take the measurement again on the connector, with the
camshaft sensor disconnected,
– If the voltage is still outside permitted tolerance values with the sensor disconnected.
Check thecontinuity and the absence of interference resistance on connection 3FB (Mégane II and Laguna
II) or 3FB1 (Scénic II) between components 756 and 1337 or 597.
If the measured voltage is correct with the sensor disconnected.
Measure the resistance of the camshaft sensor between connections 3CQ and 3FB (Mégane II and Laguna II)
or 3FB1 (Scénic II).
Replace the sensor if its resistance is not 9750 Ω < X < 10750 Ω at 20°C
If the connection or connections are faulty and there is a repair method (see Technical Note 6015A, Repairing
electrical wiring, Wiring: Precautions for repair), repair the wiring, otherwise replace it.
If the fault is still present, contact the Techline.
AFTER REPAIRDeal with any faults.
Carry out a road test followed by another check with the diagnostic tool.
