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.

1.DEF: Cruise control/Speed limiter on/off button inconsistency
NOTESConditions for applying the fault finding procedure to a stored fault:
If the fault is declared present after:
– a road test with activation of the cruise control/speed limiter function,
– the engine is started.
Special notes:
If the fault is present, the cruise control/speed limiter is switched off.
Use bornier Elé. 1681 for any operations on the injection computer connectors.
Use Wiring Diagram Technical Note, Mégane II ph2, Scénic II ph2.
Check the condition of the connector of the start/stop button for the cruise control/speed limiter (see Wiring
Diagram Technical Note, Mégane II ph2, Scénic II ph2, Component code 1081).
Check the condition of the engine management computer connector (see Wiring Diagram Technical Note,
Mégane II ph2, Scénic II ph2, component code 120).
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 button released, check the insulation between the following connections:
– Connection code 3FX of component 1081.
– Connection code AP10 of component 1081.
– Connection code 3PD of component 1081.
– Connection code AP10 of component 1081.
Check the continuity between connections 3FX and AP10 of component 1081 in the cruise control position.
Check the continuity between connections 3PD and AP10 of component 1081 in the speed limiter position.
Check the continuity and absence of interference resistance on the following connections:
– Connection code 3FX between components 1081 and 120.
– Connection code 3PD between components 1081 and 120.
Check for + 12 V on the connector of the cruise control/speed limiter button.
– Connection code AP10 of component 1081.
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 fault is still present, replace the start/stop button of the cruise control/speed limiter.

Fault finding – Interpretation of commands13B
SC017PARTICLE FILTER REGENERATION
NOTESOnly run this command after interpretation of the following faults:
– DF308 Clogged particle filter,
– DF311 Failed regenerations limit exceeded,
– DF312 Speed request.
WARNING
It is essential to observe the health and safety regulations (see MR364 (Megane II ph2), MR370 (Scenic II
ph2), Mechanical, 19B, Exhaust, Particle filter: Cleaning) and observe the following procedure.
SAFETY INSTRUCTIONS TO BE FOLLOWED:
The regeneration causes exhaust fumes and high temperatures.
The vehicle must be outside during regeneration.
If it is not possible to carry out regeneration outside, use an extractor fan that can withstand the very high
regeneration temperatures (400°C at the exhaust outlet).
Perform regeneration on a surface free from fire risks (oil, dry leaves, etc.). Nothing should be left in the vicinity
of the exhaust pipe.
IMPORTANT
– Check the engine oil level before running the command to avoid any engine racing. The oil level must
be between the minimum threshold and the middle level on the oil dipstick.
– Before performing a particle filter regeneration, it is essential to deactivate the air conditioning
compressor (risk of engine damage) and all the electrical consumers.
IF NECESSARY:
Regeneration can be stopped by briefly pressing the vehicle start button twice (less than 3 seconds).
Switch off the ignition and wait for the diagnostic tool message (maximum time 8 minutes) Communication lost
with computer: EDC16C36, check the tool connection and the computer supply. before switching on the
ignition again.
PROCEDURE TO BE FOLLOWED:
Before a particle filter regeneration, check that there are no leaks or blockages in the exhaust pipe,
Repair if necessary
To run this command, select the command mode on the diagnostic tool, and select command SC017 Particle
filter regeneration.
When regeneration is complete, a message will indicate whether regeneration was successful, and what
operations need to be carried out (filter replacement, whether an oil service is required, etc.).
