Procedure
To save energy, the vehicle's UCH interrupts the + after ignition feed after 3 minutes.
To run fault finding on a computer, it is possible to force the + after ignition feed for 1 hour by applying the following
procedure:
– press the unlocking button on the card,
– insert the card in the reader,
– press the start button (interrupting the timed + after ignition feed mode),
– press the start button for more than 5 seconds, without conditions for starting being met, until the immobiliser
warning light flashes rapidly (4 Hz).
This forced + after ignition feed mode is active for 1 hour.
Pressing the start button or removing the card from the card reader interrupts the forced + after ignition feed, but
does not interrupt the time period for the forced + after ignition feed. Until one hour has elapsed, activating the +
after ignition feed will restart forced + after ignition feed for the remaining time. Vehicle(s): MEGANE II phase 2, SCENIC II

Faults
Faults are declared present or stored (depending on whether they appeared in a certain context and have
disappeared since, or whether they remain present but are not diagnosed within the current context).
The present or stored fault status must be considered, when the diagnostic tool is used after switching on the +
after ignition feed (without operating the system components).
For a present fault, apply the procedure described in the Interpretation of faults section.
For a stored fault, note the faults displayed and apply the Notes section.
If the fault is confirmed when the instructions are applied, the fault is present. Deal with the fault.
If the fault is not confirmed, check:
– the electrical lines which correspond to the fault,
– the connectors for this connection,
– the resistance of the faulty component,
– the condition of the wires.
Conformity check
The purpose of the conformity check is to check data that does not produce a fault on the diagnostic tool if the data
is inconsistent. Therefore, this stage is used to:
– carry out fault finding on faults that do not have a fault display, and which may correspond to a customer complaint.
– check that the system is operating correctly and that there is no risk of a fault recurring after repair.
The conformity check is a fault finding procedure carried out using the interpretation of statuses and parameters.
If a status does not function normally or a parameter is outside the permitted tolerance values, consult the
corresponding fault finding page (see interpretation of statuses and parameters).
Customer complaints - Fault finding chart
If the test with the diagnostic tool is OK but the customer complaint is still present, the fault should be dealt with by
customer complaints
A synopsis of the general procedure to follow is provided on the following page in the form of a flow chart.

If all the criteria are met, the computer enters regeneration mode. The injection programming is adjusted in order to
raise the target exhaust gas temperature between 550 and 650°C.
This temperature allows the particles accumulated in the filter to be partially or completely burnt (regenerated).
Regeneration efficiency depends on the particle filter inlet temperature and the time spent in regeneration mode.
Regeneration can be carried out automatically when driving if the weight of soot is less than 70 g and if the number
of regeneration attempts when driving is less than 11 (only for Vdiag 48).
If the weight of soot is greater than 70 g, the user will have to request an After-sales regeneration.
This regeneration is carried out in the workshop. Always follow the instructions written in the interpretation of
commands (SC017 Particle filter regeneration) to perform regeneration in complete safety.
After an After-sales regeneration, always reconfigure certain parameters in the computer using command SC036
Reinitialise programming (see "interpretation of commands").
Warning light management:
Instrument panel display
The computer displays certain information on the instrument panel relating to engine operation. This involves six
functions:
– the pre-postheating warning light,
– the coolant temperature warning message,
– the level 1 fault warning light (non-critical fault),
– the level 2 fault warning light (emergency stop),
– the OBD warning light (European On Board Diagnostic),
– the particle filter specific warning light (F9Q816 engine only).
These six functions are represented by 6 warning lights and/or messages displayed by the on-board computer.
In addition, certain warning lights are, when lit, accompanied by a spoken message on vehicles fitted with a voice
synthesiser (refer to the driver's handbook).
A 3 second visual inspection (automatic test procedure managed by the instrument panel) is carried out by the
injection computer when the ignition is switched on.IMPORTANT
The particle filter must be replaced after a period of time which largely depends on the grade of engine oil used -
this information is in the driver's handbook.
After replacing it, always reconfigure certain parameters in the computer using command SC036 Reinitialise
programming (see "interpretation of commands").

Orange pre-postheating warning light
This warning light is used as an in-operation indicator lamp:
– Continuously lit under + after ignition feed: indicates preheating of the heater plugs.
It goes out when preheating is complete and the engine is able to start.
Orange "SERVICE" non-critical fault warning light (level 1)
This warning light is used to indicate a fault in the system:
– Continuously lit with the CHECK INJECTION message:
Indicates a level 1 fault (involving operation of the injection system in defect mode).
The driver should have the repairs carried out as soon as possible.
Temperature/red emergency STOP (level 2) warning light
This indicator light is used both as an in-operation indicator light and as a system fault warning light.
– Intermittently lit with the ENGINE OVERHEATING message:
Indicates that the coolant temperature is too high (the driver is free to stop the vehicle or not).
– Continuously lit with the INJECTION FAULT: STOP THE ENGINE message and an audible beep 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.
European On Board Diagnostic excess pollution ORANGE warning light
Engine symbol with the CHECK EMISSION CONTROL message.
This warning light comes on if the system has one or more OBD faults.
This warning light is used to alert the driver to injection faults that could lead to excessive pollution, or if the EOBD
system (European On Board Diagnostic) has been deactivated.
The injection computer requests illumination of the OBD warning light for a present fault only after three successive
driving cycles.
The driver should have the repairs carried out as soon as possible.

COMPUTER REPLACEMENT OR REPROGRAMMING
Two operations must be performed when replacing or reprogramming the computer:
SC003 Save computer data and SC001 Enter saved data.
–Run SC003 Save computer data before replacing or reprogramming the computer. This enables certain data
to be saved in the diagnostic tool so that the new computer* can be reconfigured like the old one. The saved data
are: injector codes, EGR programming, vehicle options.
–Run SC001 Enter saved data after replacing or reprogramming the computer. This enables the data (saved by
the command SC003 Save computer data) to be rewritten in the new computer*.
If you cannot establish dialogue with the computer being replaced: you will not be able to save anything.
After replacing the computer, write the IMA codes of each injector manually using command SC002 Enter injector
codes by reading the code on each injector (see Replacing the injectors).
Only on F9Q816 engines:
– Enter the data specific to particle filter operation by running SC036 Reinitialise programming and selecting after
replacing injection computer with no save option.
Exhaust gas recirculation valve data is programmed automatically the 1st time the new computer is turned on*.
* New computer or reprogrammed computer.
Specific to the cruise control/speed limiter operation to be carried out before reprogramming of the computer:
Before reprogramming the injection computer, move the main Cruise control/Speed limiter switch to the rest
position. The information about the cruise control or the speed limiter displayed on the instrument panel
disappears.
Otherwise, if the main switch remains in the cruise control or speed limiter position during and after reprogramming,
the Cruise control/Speed limiter function will not be operational.
The procedure for resetting the function is as follows:
– Vehicle ignition on.
– Position the main switch in rest position (the computer then detects the rest position).
– Position the switch in Cruise control position to activate the Cruise control function.
– Position the switch in Speed limiter position to activate the Speed limiter function. IMPORTANT
– Switch on the diagnostic tool (mains or cigarette lighter supply).
– Connect a battery charger.
– Cut off all the electrical consumers (lights, interior lighting, air conditioning, radio CD, etc.).
– Wait for the engine to cool (engine coolant temperature < 60° and air temperature < 50°).
– During (re)programming, the instrument panel screen displays "Oil pressure fault".
Ignore this message and do not take any action in connection with it.

PROCEDURE:
Before replacing or reprogramming the computer:
–Select 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 carried out on the tool)
–select "YES".
When the save has been performed, replace the computer or carry out the programming then proceed to the next
step.
After replacing or reprogramming the computer:
–Select SC001 Enter saved data, then follow the instructions given by the diagnostic tool,
– if the VIN is not entered (see Computer identification on the main screen),
–select VP010 Enter VIN,
When both these commands have finished:
– Switch off the ignition and wait for the diagnostic tool message (maximum time 8 minutes) Communication lost
with computer: EDC16 C36, check the tool connection and computer power supply before switching the
ignition back on.
(The powerlatch duration depends on the coolant temperature and activation time of the turbocharger
coolant pump. This operation finishes when the pump is deactivated.)
– then check the system faults, and clear any stored faults,
– if there are faults, deal with the present faults,
– clear the faults from the computer memory.
Carry out a road test followed by another check with the diagnostic tool.
End of the procedure.IMPORTANT
– The injection computer retains the immobiliser code for life.
– The system has no security code.
– It is forbidden to perform tests with computers borrowed from the Parts Department or from another vehicle
which must then be returned.
– These computers are hard-coded.
– If the injection computer appears to be faulty, contact the Techline and refer to the fault finding log.

REPLACING THE INJECTORS
After one or more injectors have been replaced, enter the IMA codes again and then run command SC036
Reinitialise programming.
The system must be configured via the diagnostic socket using the RENAULT CLIP diagnostic tool.
PROCEDURE to be followed after replacing one or more injectors:
– Note the "IMA" code(s) engraved on the injector bodies,
– enter these codes in the computer using command SC002 Enter injector codes, then follow the instructions given
by the diagnostic tool,
– once the command has finished,
–switch off the ignition and wait for the diagnostic tool message (maximum time 8 minutes) Communication
lost with computer: EDC16 C36, check the tool connection and computer power supply before switching the
ignition back on.
– Return to fault finding mode.
– select the Identify computer function from the main screen.
– check that the injector codes entered into the computer match those found on the bodies of the injectors:
– If the codes do not match, restart the command SC002 Enter injector codes procedure.
– If the codes correspond, run command SC036 Reinitialise programming,
–select Injectors as the type of operation, then follow the instructions given by the diagnostic tool.
– Then check the system faults, and clear any stored faults.
– if there are faults, deal with the present faults,
– clear the faults from the computer memory.
Carry out a road test followed by another check with the diagnostic tool.
End of the procedure.Note:
The IMA coding (individual injector correction) is a calibration made in production on each injector to adjust
the flow accurately.
These correction values are etched onto the Bakelite body of each injector (7 alphanumeric characters) and then
entered into the computer which then controls each injector taking into account its individual manufacturing
variation.
IMPORTANT
Cylinder no. 1 is located on the engine flywheel end.
IMPORTANT
Engines can only operate correctly if the correct IMA codes have been entered.
If no code has been entered, or if an implausible code has been entered, fault DF276 "Injector Code
Programming" will be present, and the engine will be in defect mode (engine speed is reduced
significantly).
If another injector's code has been entered, the system will accept it but will make the wrong correction.
This could lead to engine damage, loss of performance and excessive pollution.
Always use the correct injector codes for the engine cylinder/computer.

REPLACING THE EXHAUST GAS RECIRCULATION VALVE (EGR valve)
After the exhaust gas recirculation valve has been replaced, the computer must store the new valve's offset and the
offset measured the last time the ignition was switched off, which is when the valve closed.
Using this data, the computer can detect whether the valve is clogged or seized.
When the valve is replaced, clear the stored offsets so that the program uses the new valve’s offset value.
The data linked to this strategy is compiled in the Emission control/OBD sub-function.
– PR128: First EGR valve offset.
–PR129: Last EGR valve offset > or = PR128 if the valve is new.
The PR128 and PR129 programming must be cleared every time the exhaust gas recirculation valve is replaced.
PROCEDURE to be followed after replacing the exhaust gas recirculation valve:
– Run command SC036 Reinitialise programming,
–select EGR valve as the type of operation, then follow the instructions given by the diagnostic tool,
– When the command is finished,
– switch off the ignition and wait for the diagnostic tool message (maximum time 8 minutes) Communication lost
with computer: EDC16 C36, check the tool connection and computer power supply before switching the ignition
back on.
When the ignition is next switched on again the new EGR valve offset is automatically reprogrammed.
– Start the vehicle to enable the latest EGR valve offset to be programmed,
– Switch off the ignition and wait for the diagnostic tool message (maximum time 8 minutes) Communication lost
with computer: EDC16 C36, check the tool connection and computer power supply before switching the
ignition back on.
The last EGR valve offset reprogrammed is stored on the computer.
– Then check the system faults, and clear any stored faults.
– if there are faults, deal with the present faults,
– clear the faults from the computer memory.
Carry out a road test followed by another check with the diagnostic tool.
End of the procedure.Note:
When the reinitialisation is complete, the Emission control/OBD sub-function displays:
PR128 = PR129 > 100 %
Note:
When the new EGR valve offset is reprogrammed, the Emission control/OBD sub-function displays:
10 % < PR128 < 40 %
PR129 > 100 %
Note:
When the reprogramming of the last EGR valve offset is complete, the Emission control/OBD sub-function
displays:
10 % < PR128 < 40 %
10% < PR129 < 40% and -1%
≤ PR129 – PR128 ≤ 5%
