SC001WRITE SAVED DATA
NOTESTo use this command, first save the data with the SC003 Save computer data
command.
The writing is carried out after the computer has been reprogrammed or replaced.
Ignition on and engine stopped.
Validating this command writes the data saved using command
SC003 Save computer data.
The data is as follows:
– injector codes,
– the egr valve data programming;
options available on the vehicle and managed by the computer (e.g. air conditioning);
This data will configure the computer and will prevent:
– engine malfunction after (re)programming or replacing the computer;
– faulty interpretation of information provided by the CLIP tool.

SC003SAVE COMPUTER DATA
NOTESThis save is performed before reprogramming or replacing the computer.
Ignition on and engine stopped.
On the CLIP tool, select scenario SC003 Save computer data.
If the following message appears:
"a saved file exists, do you want to overwrite this data?":
(this file corresponds to the last save made on thediagnostic tool)
select "YES".
Confirming this command saves the following vehicle-specific data:
– injector codes,
– the egr valve data programming;
– options available on the vehicle and managed by the computer (e.g.: air conditioning).
This information will be saved in the CLIP tool.
After saving has finished, use the command SC001 Enter saved data to be able to set the new computer
parameters, after programming and reprogramming.

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.).

RZ005PROGRAMMING
NOTESThis command enables you to reinitialise the entire computer configuration according
to the vehicle.
Ignition on and engine stopped.
Command RZ005 reconfigures the computer.
if the computer has no configuration data,
run command RZ005 to enter the options fitted on the vehicle:
– air conditioning,
– cruise control/speed limiter.
These options are detected by the computer even if command RZ005 is not used.
the computer is configured as soon as the one of the vehicle's optional system components is operated.

AC038LOW-SPEED FAN ASSEMBLY RELAY
NOTESThere must be no present or stored faults.
Perform this fault finding after an engine cooling fault or air conditioning fault.
Refer to the Wiring Diagram Technical Notes for the vehicle to locate the fuses and
relays concerned.
Ignition on and engine stopped.
Use Wiring Diagram Technical Note, Mégane II ph2, Scénic II ph2.
If the low speed fan assembly relay does not operate when command AC038 is run:
Check the low-speed fan assembly relay mounting and the connections of the engine management computer.
Check the fan assembly connections.
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, check that the relay is actuated by the engine management computer as follows:
Disconnect the low-speed fan assembly relay, and fit a 50 to 100 Ω resistor on the relay mounting in place of the
coil, and connect a voltmeter as follows:
– positive terminal to +12 V battery,
– negative terminal to connection 3JN of component 336.
Run command AC038
If the voltmeter shows the battery voltage (4 ON-OFF cycles of 10 seconds), replace the relay.
If the low speed fan assembly relay is supplied using command AC038, but there is still a fan assembly activation
fault, check using the wiring diagram.
The conformity of the fan assembly FM15 maxi-fuse.
