SPEED REQUESTED BY HEATING/AIR CONDITIONING
PARAMETER
DEFINITIONThis parameter indicates the engine's speed of rotation with air conditioning in rpm.
NOTESSpecial notes:
Only perform these tests if the parameters do not correspond with the system
operation programming.
Conformity check with engine running, engine coolant temperature > 80°C.
The engine speed requested by the air conditioning is increased and fluctuates around 875 rpm.
This parameter is only valid when the engine has been started.
AFTER REPAIRCarry out a road test, then check with the diagnostic tool.

WRITE SAVED DATA
NOTESAll data must be saved with command SC003 Save computer data for this command
to be run.
writing is carried out after the computer has been reprogrammed or replaced
Validating this command writes the data saved using command SC003 Save computer data.
The data is as follows:
– vehicle idle speed.
– injector calibration codes (if the vehicle is fitted with ima).
– programming of exhaust gas recirculation valve data.
– options available on the vehicle and managed by the computer (example: air conditioning).
– specific data related to the operation of the particle filter.
they will configure the computer and will enable it to avoid:
– engine malfunction after reprogramming or replacing the computer,
– faulty interpretation of information provided by the clip tool.

SAVE COMPUTER DATA
NOTESperform this backup before computer reprogramming or before replacing the
computer
Select scenario SC003 on the CLIP tool.
If the following message appears:
"a saved file exists, do you want to overwrite this data?":
(this file corresponds to the last save carried out on the 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);
– specific data related to the operation of the particle filter.
This information will be saved in the CLIP diagnostic 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.

PARTICLE FILTER REGENERATION
NOTESonly run this command after the 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 (mégane ii ph2), mr370 (scénic ii
ph2), mr 395 (laguna ii ph2), mechanical systems 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 which can withstand 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.
Check that there are no leaks or blockages in the exhaust pipe,
Repair if necessary
WARNING:
– 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 wait 8 minutes): Loss of dialogue
with the computer: EDC16C3, check the tool connection and the computer supply, before switching the
ignition back on.
PROCEDURE TO BE FOLLOWED:
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 or if any other
operations need to be carried out (filter replacement, whether an oil change is required, etc.).

PROGRAMMING
NOTESthis command enables you to reinitialise the entire computer configuration according
to the vehicle.
Command RZ005 reconfigures the computer.
if the computer has no configuration data,
use command RZ005 to enter the options fitted on the vehicle:
– air conditioning,
– thermoplungers,
– 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.

LOW-SPEED FAN ASSEMBLY RELAY
NOTESThere must be no present or stored faults.
Perform this fault finding procedure if a malfunction appears on the command menu
or after an engine cooling system or air conditioning fault.
Refer to the Wiring diagrams Technical Note for the vehicle to locate the fuses and
relays concerned.
If the low-speed fan assembly relay does not operate when command AC038 is run:
Check the low speed fan relay mounting and the connections of the engine management computer.
Repair if necessary.
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, fit a 50 Ω < X < 100 Ω resistor on the relay mounting in place of
the coil, and connect a voltmeter as follows:
Positive terminal to the +12 V battery.
Negative terminal to connection 3JN of the low-speed fan assembly relay mounting.
Clear the fault and run command AC038
If the voltmeter indicates the battery voltage (three 2-second ON-OFF cycles), replace the relay.
If the voltmeter does not show the battery voltage (three 2 second ON-OFF cycles), contact the techline.
If the low speed fan assembly relay operates when command AC038, is run, but there is still a fan assembly
activation fault, use the wiring diagram to check the following:
– the conformity of the fan assembly maxi-fuse.
– the conformity of the low-speed fan unit relay,
– the continuity of connection 49L between components 597 and 321.
– the continuity of connection 49B between components 321 and 262.
– the conformity of the fan assembly and the continuity of connection MAS of component 262.
Carry out the necessary repairs.

HIGH-SPEED FAN ASSEMBLY RELAY
NOTESThere must be no present or stored faults.
Perform this fault finding procedure if a malfunction appears on the command menu
or after an engine cooling system or air conditioning fault.
Refer to the Wiring Diagrams Technical Note for the vehicle to locate the fuses and
relays concerned.
If the high-speed fan assembly relay does not operate when command AC039 is run:
Check the high-speed fan assembly relay mounting and the connections of the engine management computer.
Repair if necessary.
If the fault is still present, check that the relay is actuated by the engine management computer as follows:
Disconnect the high-speed fan assembly relay, fit a 50 Ω < X < 100 Ω resistor on its mounting in place of the
coil, and connect a voltmeter as follows:
Positive terminal to the +12 V battery.
Negative terminal to connection 3JP of the high-speed fan assembly relay mounting.
Clear the fault and run command AC039.
If the voltmeter indicates the battery voltage (three 2-second ON-OFF cycles), replace the relay.
If the voltmeter does not show the battery voltage (three 2 second ON-OFF cycles), contact the techline.
If the high-speed fan assembly relay is supplied by command AC039, but there remains a fault with the
triggering the fan assembly. Check using the wiring diagram:
– the conformity of the fan assembly maxi-fuse.
– + battery feed on connection BP71 of the high-speed fan assembly relay mounting,
– the conformity of the high-speed fan assembly relay,
– the continuity of connection 49B between components 597 and 262,
– the conformity of the fan assembly,
– the continuity of connection MAS of component 262.
Carry out the necessary repairs.
