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).

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.

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

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.

SC017PARTICLE FILTER REGENERATION
NOTESOnly run this command after interpretation of the following faults:
– DF308 Clogged particle filter,
– DF311 Failed regenerations limit exceeded,
– df312: speed request.
WARNING:
– It is essential to observe the health and safety guidelines (see MR364 (Mégane II ph2), MR370 (Scénic II ph2),
MR 395 (Laguna II ph2), 402 (Vel Satis ph2), 405 (Espace IV ph2) Mechanical, 19B, Exhaust, Particle
filter: Cleaning) and follow the procedure below.
SAFETY INSTRUCTIONS TO BE FOLLOWED:
The regeneration causes exhaust fumes and high temperatures.
It is strongly recommended that you put the vehicle outside during regeneration.
If it is not possible to carry out regeneration outside, use an extractor fan that can withstand the very high
regeneration temperatures (400°C at the exhaust outlet).
Perform regeneration on a surface free from fire risks (oil, dry leaves, etc.).
Nothing should be left in the vicinity of the exhaust pipe.
Check that there are no leaks or blockages in the exhaust pipe,
Repair if necessary.
WARNING:
Check the engine oil level before running the command to avoid any engine racing. The oil level must be
between the minimum level and the middle level on the oil dipstick.
Before performing a particle filter regeneration, it is essential to deactivate the air conditioning
compressor (risk of engine damage) and all the electrical consumers.
IF NECESSARY:
Regeneration can be stopped by pressing the engine start button twice briefly (less than 3 seconds).
Switch off the ignition and wait for the diagnostic tool message (maximum time 8 minutes) Communication
lost with computer: EDC16 C33, check the tool connection and the computer power supply before
switching the ignition back on.

AC004TURBOCHARGING SOLENOID VALVE
NOTESPerform this fault finding procedure:
– following interpretation of an unresolved fault or,
– following application of the interpretation of PR041 Turbocharging pressure or
– after a customer complaint (loss of power, smoke etc.).
Use the Wiring Diagram Technical Note, Laguna II ph2, Vel Satis ph2, Espace IV
ph2, Mégane II ph2, Scénic II ph2.
1. The following procedure is for checking that the turbocharger and its control circuit are working
properly.
Preliminary operation
Check the high pressure air circuit is sealed:
Apply Test 4 Turbocharged air inlet circuit check or Test 3 Low pressure circuit check.
Pipe not joined or pierced, pressure sensor disconnected or poorly fitted (seal present), exchanger pierced.
To test the exchanger: stabilise the engine speed between 3500 and 4000 rpm with the vehicle stopped and
check that there are no leaks.
Measure the resistance between connections3FB and 3MG of component1475.
If the resistance is not between 18 Ω and 22 Ω at + 23°C, replace the turbocharging solenoid valve.
Check the continuity of the following connection:
•3MG between the components 120 and 1475.
Check the + 12 V after relay supply of the turbocharging solenoid valve on the following connection:
•3FB of component 1475.
If the connection or connections are faulty and there is a repair procedure (see Technical Note 6015A, Electrical
wiring repair, Wiring: Precautions for repair), repair the wiring, otherwise replace it.

NOTESCarry out this interpretation:
– after DF645 Damper valve position regulation, DF646 Damper valve position
sensor,
– or after a customer complaint (starting faults, poor performance).
Use the Wiring Diagram Technical Note, Laguna II ph2, Mégane ll, Scénic ll,
Espace IV ph2, Vel Satis ph2.
Measure the resistance between connections 38KQ and 38KP of component 1461.
If the resistance is not between 875 Ω and 1625 Ω replace the damper valve.
Check the continuity and absence of interference resistance of the following connections:
•38KQ between components 120 and 1461,
•38KP between components 120 and 1461.
If the connection or connections are faulty and there is a repair procedure (see Technical Note 6015A, Electrical
wiring repair, Wiring: Precautions for repair), repair the wiring, otherwise replace it.
With the vehicle ignition on, and the engine stopped:
Make sure the damper flap is open,
If not, clean or replace the damper valve.
Actuate the valve using command AC012 and check the damper valve travel and rest position of the valve.
Check the operation of the computer output stage with a voltmeter in the alternating current position:
Actuate the valve with command AC012.
Connect the voltmeter earth lead to connection 38KS of component 1461 and the positive lead to connection
38KQ of component 1461.
The voltmeter should display three cycles of ON-OFF (12.5 V then return to 0V).
If the measurement is correct, replace the damper valve
If the measurement does not show any operation, contact the Techline.
