PR863DAMPER VALVE POSITION FEEDBACK
PARAMETER
DEFINITIONThis parameter indicates the damper valve opening ratio.
NOTESNone.
Conformity check with engine stopped and ignition on.
PR863 ≈ PR747 Damper valve position
The damper valve opening percentage value must be:
PR863 = 0% (with the engine stopped),
PR863 ≈ 5% (with the ignition on).
In the event of a fault, consult the interpretation of faults DF646 Damper valve position sensor and DF323
Damper valve.
Conformity check with the engine running and engine coolant temperature > 80°C
The damper valve opening percentage value must be:
PR863 ≈ 5% (at idle speed).
In the event of a fault, refer to the interpretation of faults DF646 and DF323.

PR873OIL OXIDATION SIGNAL
STATUS
DEFINITIONThis parameter indicates the vehicle distance in miles (km) when the oil oxidation
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 the ignition on, or Engine running and the engine coolant
temperature > 80°C without electrical consumers
The oil condition is calculated by the oxidation program in the injection computer, according to the number of
engine revolutions.
When this count reaches a certain threshold before the end of the oil service period, the injection computer sends
a signal to the instrument panel, which will display service due. Parameter PR873 corresponds to the vehicle
mileage at the time this signal is sent.
Then the instrument panel computer deducts 900 miles (1500 km) before displaying the message Service
required.
IMPORTANT:
When the message Service due appears on the instrument panel, the customer must have the oil changed within
the remaining 900 miles (1500 km).

DEFINITIONThis parameter indicates the vehicle's mileage at the last service in miles (km).

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.

SC001WRITE SAVED DATA
NOTESTo use this command, first save the data with the SC003 Save computer data
command.
The writing is carried out after the computer has been reprogrammed or replaced.
Engine stopped.
In the diagnostic tool, select scenario SC001.
Note:
If no files have been saved before, a write error appears when command SC001 is activated.
Validating this command writes the data saved using command SC003 Save computer data.
The data is as follows:
– vehicle-specific idling,
– injector codes,
– various offsets for components, EGR, damper valve,
– options available on the vehicle and generated by the computer.
This data will configure the computer and will prevent:
– engine malfunction after reprogramming or replacing the computer,
– incorrect interpretation of the information provided by the diagnostic tool.

SC002ENTER INJECTOR CODES
NOTESThis command is carried out after the replacement of one or more injectors.
Engine stopped.
To enter this information, select command SC002 in the diagnostic tool.
Procedure to be followed:
– Read the 7-character alphanumeric codes engraved on the upper section of the injector bodies. The IMA*
codes should be read from left to right (see illustration in MR 402 (Vel Satis ph2), MR 395 (Laguna II ph2),
MR 364 (Mégane II ph2), MR 370 (Scénic II ph2), MR 405 (Espace IV ph2) Mechanical, 13B, Diesel
injection, Diesel injector, Removal – Refitting)
Note: When entering characters, confusion can arise between:
– Figure 1 with the letters I and L,
– Figure 2 with the letter Z,
– Figure 5 with the letter S,
– Figure 6 with the letter G,
– Figure 8 with the letter B.
After programming or reprogramming the computer, it is essential to enter the 4 injector codes before confirming
the entry.
– Enter each injector code for the associated cylinder.
–Important: cylinder no. 1 is located at the timing end.
– Confirm the change of injector code configuration.
– When the command is completed, the modified codes appear in the current column.
– Check that the codes correspond to those read earlier.
If the codes entered appear in neither the "current" column nor the "desired" column, check the codes read and
make sure the data has been entered correctly.
– Exit fault finding mode.
– Switch off the ignition and wait for the diagnostic tool message (maximum wait 8 min): Loss of dialogue with
the computer: EDC16 CP33, check the tool connection and the computer supply.
– Switch the ignition back on and check for faults.
–DF066 Injector code(s) should be stored.
