Fault finding – Function13B
INTERSYSTEM EXCHANGES
The inter-system connections concerning the particular requirements of engine management are as follows:
●Request for injection computer to switch on the OBD warning light to warn of an OBD related pollution fault.
●Request to switch on the Level 1 warning light to warn of an operational safety fault with the engine
management system which may restrict performance.
●Request to switch on the Level 2 warning light to warn of an operational safety fault with the engine
management system which may result in the engine stopping.
●Request to switch on the Particle Filter and Service warning light to warn of an operational safety fault of the
particle filter system which may result in reduced performance or engine stoppage.
●Request to switch on the Engine overheating warning light to warn of an engine overheating fault or a fault
in the coolant temperature sensor.
●Request to switch on the Particle filter warning light to warn the driver that the particle filter is loaded with
particles (weight of soot more than 30.8 g). As soon as possible, the driver must drive at a speed of more than
25 mph (40 km/h) for 2 minutes to activate regeneration.
The driver must maintain a speed of more than 25 mph (40 km/h) until the particle filter warning light goes out
(Vdiag 45 and 49 only).
●Request to start the fan assembly for engine cooling and also for air conditioning purposes,
●Request to switch off the air conditioning compressor for engine programming requirements such as pulling
away, performance, anti-stalling, overspeed, etc.
●Request to switch off electrical consumers (passenger compartment heating resistor (if fitted), heated rear
screen, etc.) for engine operation purposes such as: pulling away, performance, anti-stalling,
overspeed, etc.
●Formulation of requests to engage electrical consumers and limit power as a function of rail conditions.
This last function is made possible with the introduction of alternator control. Formulation of requests enables
the smooth running of the engine to be improved in the critical operating phases, mainly at idle speed and
when pulling away. These requests pass via the multiplex network to the Protection and Switching Unit where
they are converted before being sent to the alternator.
In comparison to the version without a particle filter (K9K Step 2), the K9K Step 2 particle filter technical
specifications also include:
●Four temperature sensors spread along the exhaust system.
●One differential pressure sensor.
●One fuel injector with a dedicated electric fuel pump.
●An electric water pump (in addition to the mechanical pump) controlled by a relay to cool the turbocharger when
the engine is stopped (only for Clio III, Modus and Mégane II/Scénic II).
●Four heating elements and their control unit.
Oil Control System (OCS) (except Vdiag 44, 45 and 49)
This program takes into account the driving style of the user to warn him of the need for an oil change. This program
counts the number of miles since the last oil change, corrected by a factor which depends on the oil temperature.
When the number of miles exceeds a threshold, the customer is warned by a message to the instrument panel that
the drain must be performed.
After the oil change, the user must reset the oil change interval on the instrument panel.

OIL OXIDATION SIGNAL
PARAMETER
DEFINITIONThis parameter indicates the vehicle mileage when the oil oxidation threshold is
reached.
NOTESOnly apply the interpretation of this parameter if the OCS (oil control system)
program is activated on the instrument panel. Check on the instrument panel computer
that the configuration reading LC106 O.C.S. is set to WITH.
Except Vdiag 44, 45 and 49.
Conformity check: Engine stopped and the ignition on, or the engine running and the engine coolant
temperature > 80°C, without electrical consumers
The oil status is calculated by the oxidation program in the injection computer, depending on the engine revs.
When this count reaches a certain threshold before the end of the oil change period, the injection computer sends
a signal to the instrument panel, which will display "service required soon". PR873 corresponds to the vehicle
distance at the time this signal is sent.
The instrument panel computer counts down 900 miles (1500 km) before displaying the message "service
required".
IMPORTANT
When the message "service required" appears on the instrument panel, the customer must arrange an oil
service within the remaining 900 miles (1500 km).
AFTER REPAIRDeal with any faults displayed by the diagnostic tool.
Clear the computer memory.
Carry out a road test followed by another check with the diagnostic tool.

OIL DILUTION SIGNAL
PARAMETER
DEFINITIONThis parameter indicates the vehicle mileage when the oil dilution threshold is reached.
NOTESThis parameter should be interpreted only if the OCS (Oil Control System) program
is activated on the instrument panel. On the instrument panel computer, check the
configuration reading LC106 O.C.S: WITH.
Except Vdiag 44, 45 and 49.
Conformity check: Engine stopped and the ignition on, or the engine running and the engine coolant
temperature > 80°C, without electrical consumers
The injection computer assesses the dilution rate of the engine oil according to the customer's driving style.
When the dilution level reaches a certain threshold before the end of the oil change interval, the injection
computer sends a signal to the instrument panel, which then displays Service required. Parameter PR875
corresponds to the vehicle mileage at the time this signal is sent.
IMPORTANT
When the message Service required appears on the instrument panel, the customer must arrange an immediate
oil change to prevent damage to the engine.
AFTER REPAIRDeal with any faults displayed by the diagnostic tool.
Clear the computer memory.
Carry out a road test followed by another check with the diagnostic tool.

PARTICLE FILTER REGENERATION
NOTESCarry out this command only under the following conditions:
– DF308 Clogged particle filter present.
Ignition on and engine stopped.
Vdiag 45, 49 and 4D only.
WARNING:
–It is essential to carry out the next procedure in accordance with the safety and cleanliness guidelines,
(see MR 364 (Mégane II), 370 (Scénic II), 417 (Kangoo II), 385 (Modus), 392 (Clio III), Mechanical, 19B,
Exhaust, Particle filter: Cleaning).
– do not run command AC029 High pressure circuit seal test until regeneration has finished.
– before each regeneration, check the fuel level,
– before and after each regeneration, check the oil level.
With the engine running and the vehicle stopped, this function allows the particle filter to be regenerated.
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, check that the extractor fan can withstand the very high
regeneration temperatures.
Perform regeneration on a surface free from fire risks (oil, dry leaves, etc.).
Nothing should be left in the vicinity of the exhaust pipe.
Before regeneration:
– Respect After-Sales recommendations for particle filter regeneration.
– Check the oil level to prevent the engine from racing.
– Check the fuel level.
– Check the sealing on the 5th particle filter injector circuit using actuator AC237 Fuel pump relay.
– Check that there are no leaks or blockages in the exhaust pipe,
To perform regeneration:
– Vehicle stopped and in neutral.
– Engine running and warm.
– No pedal depressed (accelerator and clutch).
– No faults present preventing regeneration from being carried out on the system.
– No leak in the 5th particle filter injector circuit.
AFTER REPAIRDeal with any faults displayed by the diagnostic tool.
Clear the computer fault memory.
Carry out a road test followed by another check with the diagnostic tool.

CONTINUED
After-Sales regeneration comprises 4 important stages:
– Heating of the engine and checking for a small quantity of soot in the particle filter by measuring the differential
pressure.
– The system changes from combustion mode and starts to regenerate the particle filter. Gradual cooling of the
particle filter.
– End of After-Sales regeneration.
Stopping conditions:
– Dialogue with the diagnostic tool has been lost.
– Vehicle movement detected by speed sensor.
– Brake or clutch pedal depressed.
– Stop regeneration requested by the diagnostic tool.
– End of test.
The procedure lasts 30 minutes.
– At the end of regeneration, a message announces whether the regeneration has been successful or which
operations to carry out.
CONFIRMING THE REGENERATION PROCESS:
At the end of regeneration, a message appears to announce whether the regeneration was successful:
particle filter regeneration successful: regeneration completed correctly.
weight of soot too high - run command SC017 again: regeneration failed because the weight of soot at
the end of regeneration was too high and the temperature upstream of the particle filter was too low. Check
the oil level before starting another regeneration.
weight of soot too high: regeneration failed because the weight of soot at the end of regeneration was
too high in spite of the correct temperature upstream of the particle filter. The particle filter is full of residue
(regeneration impossible), refer to the fault finding chart ALP21 Particle filter warning light lit.
present or stored fault: regeneration failed because faults were declared.
Refer to the interpretation of faults, after resolving the faults, run command SC017 again.
AFTER REPAIRDeal with any faults displayed by the diagnostic tool.
Clear the computer fault memory.
Carry out a road test followed by another check with the diagnostic tool
