Catalysed particle filter management (for F9Q816 engine only):
The particle filter prevents the escape of carbon particles emitted by the engine but not yet removed from the
exhaust gases.
The particle filter is a microporous structure containing channels arranged so as to force-filter the exhaust gases.
The exhaust pipe consists of several components:
– an oxidation catalytic converter mounted after the turbocharger. This catalytic converter ensures that HC/CO levels
meet current standards by generating the heat (rise in exhaust temperature caused by catalysis) required for
particle filter regeneration.
– a particle filter located under the body,
– a differential pressure sensor to inform the computer of the pressure difference upstream and downstream of the
particle filter
– a particle filter upstream temperature sensor,
– a particle filter downstream temperature sensor (only on certain F9Q816 engines in VDiag 48),
– a temperature sensor upstream of the turbine (TAVT).
During driving, the particle filter becomes loaded with particles of soot. When a given weight of soot determined by
computer mapping is reached, regeneration mode can be triggered if the maximum weight of soot in the particle filter
has not been reached and the engine operating conditions are met (coolant temperature, etc.)
Particle filter regeneration consists of burning the particles of soot that have accumulated in the filter.
The differential pressure sensor measures the particle filter inlet/outlet pressure differential; this measurement is
used to estimate the weight of soot present in the particle filter by mapping in the computer:
(soot weight = pressure differential as a function of exhaust volume flow rate).

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 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.

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.
