PR875OIL DILUTION SIGNAL
STATUS
DEFINITIONThis parameter indicates the vehicle mileage in miles (km) when the oil dilution
threshold is reached.
NOTESThis parameter should only be interpreted 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.
Conformity check: Engine stopped and ignition on, or engine running and engine coolant
temperature > 80°C without electrical consumers
The injection computer estimates the degree of engine oil dilution 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.

PR1012WEIGHT OF SOOT AFTER REGENERATION
STATUS
DEFINITIONThis parameter indicates the weight in g of soot present in the particle filter following
regeneration.
NOTESThis parameter should be consulted after running SC017 Particle filter regeneration.
Conformity check: Engine stopped and ignition on, or engine running and engine coolant
temperature > 80°C without electrical consumers
If this parameter is less than 15 g, particle filter regeneration was successful.
If PR1012 is greater than 15 g, it is necessary to perform a second particle filter regeneration using command
SC017 Particle filter regeneration.
IMPORTANT:
Before performing a second After-Sales regeneration of the particle filter, the engine must be allowed to cool down
for 2 hours with the bonnet open.
Do not carry out an engine oil change before a second After-Sales regeneration.

SC017

PROCEDURE TO BE FOLLOWED:
To run this command, select the command mode on the diagnostic tool and run command SC017.
When regeneration is complete, a message will indicate whether regeneration was successful, and what
operations need to be carried out (filter replacement, whether an oil service is required, etc.).
DESCRIPTION OF THE PROCESS
particle filter regeneration takes place in 3 stages (values given as a guide only):
Heating phase: the speed is fixed or fluctuating around 3000 rpm.
– This phase lasts at least 6minutes, until the coolant temperature is above 80°C.
–Regeneration phase: the speed is fixed or varies around 2000 rpm. Engine injection is retarded. The exhaust
fumes rise in temperature and burn the soot retained in the particle filter. The particle filter downstream
temperature starts to rise after the particle filter upstream temperature due to the volume of the particle filter.
Then the combustion of the soot stored in the particle filter causes the particle filter downstream temperature
to increase, possibly reaching more than 700°C depending on the amount of soot in the filter (with a particle
filter upstream temperature of around 600°C). This phase lasts about 30 minutes.
–Cooling phase: the engine speed is fixed or varies around 2000 rpm.
– Engine injection returns to normal and the exhaust gases cool the particle filter.
– This phase lasts 3 minutes. At the end of this period, the engine speed returns to idle speed or remains fixed
at 2000 rpm.
The process lasts at least 40 minutes (the regeneration time will be increased depending on how long it takes
for the coolant to heat up to 80°C).

MT001TURBOCHARGING FUNCTION
NOTESPerform this fault finding procedure:
– following the interpretation of a fault concerning the air line which cannot be rectified,
– following an inconsistency found in the parameters concerning the air line
(turbocharging pressure or inlet air flow),
– following a customer complaint (starting faults, engine speed instability, lack of
power).
NOTESThis fault finding mode allows you to check dynamically certain mechanical components
on the engine.
To do this, the engine will run a 4-phase cycle which will enable the entire air line to be
checked: air filter, air flowmeter, duct (hoses), air refrigerant, turbocharging pressure
sensor, turbocharger, inlet manifold, exhaust manifold and exhaust pipe.
This test lasts for approximately 50 seconds.
Interpretation of test results:
The data recorded during this test is displayed in the DATA section.
- Identify any data which is outside the tolerance range and apply the different Monitool fault finding procedures
if necessary.

– PR055 Engine speed
– PR035 Atmospheric pressure
– PR059 Inlet air temperature
– PR064 Coolant temperature

PHASE 1:
Preliminary test:
Engine speed between: 2480 rpm < X < 2520 rpm
Coolant temperature > 70°C
EGR valve feedback position < 1%
If data from the preliminary checks indicates a non-conformity, check the fuel circuit then contact the Techline.
Interpretation:
If, during phase 1, no data is outside the maximum and minimum limits for each variable, interpret the Monitool
analysis for phase 2.

Interpretation:
If, during phase 2, no data is outside the maximum and minimum limits for each variable, interpret the Monitool
analysis for phase 3.
Note: the interpretation of faults during phase 2 should only be carried out in the following situation:
– The variables measured during phase 1 are correct, i.e. they are within the maximum and minimum authorised
limits. If this is not the case, apply the different Monitool fault finding procedures which relate to the different faults
revealed during the phase 1. To confirm the repairs or modifications carried out, run the MT001 monitool test
again.

Interpretation:
If, during phase 3, there is no data outside of the maximum and minimum limits for each variable, then the air line
is correct and no component replacement is to be carried out. Check the fuel circuit or deal with present or stored
faults which are displayed on the diagnostic tool.

– The variables measured during phase 1 and 2 are correct, i.e. they are within the minimum and maximum
