ORANGE particle filter specific warning light (F9Q816 engine only):
F9Q816 Vdiag 48 engines:
This warning light is used to warn the driver that the particle filter is loaded with particles (weight of soot greater than
36 g or more than 6 regeneration failures while driving due to driving conditions not being favourable for
regeneration). As soon as possible the driver must then drive at an average speed of 48 mph (80 km/h) subject to
the road conditions and authorised speed limits.
F9Q816 Vdiag 50 engines:
This warning light is used to warn the driver that the particle filter is loaded with particles.
European On Board Diagnostic management:
The OBD (On Board Diagnostic) system permits detection of any faults relating to the vehicle emission control
system (OBD EURO IV emission control standards being exceeded).
This system should be active for the entire life of the vehicle.
1. Conditions of an OBD fault appearing
An OBD fault will be detected after 3 trip cycles.
It allows the driver to know whether the vehicle has a fault directly linked to the emission control system.
2. System faults displayed by the OBD
List of the faults recorded by the OBD system:
– DF002 Air temperature sensor circuit.
– DF004 Turbocharging pressure sensor circuit.
– DF011 Sensor supply voltage no. 1.
– DF012 Sensor supply voltage no. 2.
– DF013 Sensor supply voltage no. 3.
– DF026 Cylinder 1 injector control circuit.
– DF027 Cylinder 2 injector control circuit.
– DF028 Cylinder 3 injector control circuit.

Some repair operations require programming to ensure that certain engine components function correctly.
Follow the programming procedures (see Replacement of components), if replacing the exhaust gas
recirculation valve or an injector.
*temp: temperature
* diff: differential
3. Conditions for deleting an OBD fault
An OBD fault is deleted in several phases.
The fault present on the diagnostic tool will only become stored (after a repair operation) after the vehicle has
been driven 3 times.
The OBD warning light will only go out after these 3 trips.
The instrument panel warning light coming on does not automatically mean that the system has a fault.
In order for the OBD fault and display parameters to be cleared from the computer, the system requires
40 engine heating cycles.
An engine heating cycle is a driving cycle during which:
– the engine coolant temperature reaches at least 71.1°C,
– the engine coolant temperature varies by 22.2°C in relation to the engine starting temperature.
If one of these conditions is not fulfilled, the OBD fault will still be present or stored on the injection
computer.

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.

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.
