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.

SC017
CONTINUED 1
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.
Introduction:
Engine parameters used during this test:
– PR055 Engine speed
– PR035 Atmospheric pressure
– PR059 Inlet air temperature
– PR064 Coolant temperature
–PR132 Air flow
– PR041 Turbocharging pressure
– PR051 EGR valve position feedback

TEST3 Low pressure circuit check
Check the fuel filter:
– Conformity of the fuel filter (correct part number and RENAULT filter).
– Positioning and degree of clogging of the filter cartridge.
– Positioning and condition of the seals.
– If there is metal swarf in the filter:
Replace the fuel filter, bleed the circuit and continue the fault finding procedure.
Supplying the injection system with fuel from an additional tank.
This operation aims to detect possible faults in the low pressure supply system of a vehicle by replacing it entirely
with an additional tank.
Mode:
– Disconnect the diesel fuel supply pipe at the fuel filter inlet and block it with a plug.
– Connect a pipe to the fuel filter inlet and insert the other end in a clean container with a capacity of approximately
5 litres.
– Disconnect the diesel fuel return pipe at the diesel temperature sensor (pump return and injector return join), and
block it using a plug.
– Connect a transparent pipe to the union of the diesel fuel temperature sensor, and insert the other end in the
container.
– Fill the container with clean diesel fuel.
– Start the engine and let the system drain itself of its air (there must not be any air bubbles in the return pipe).
Is the customer complaint still present?If the low pressure circuit is in order, reconnect the
various low pressure circuit pipes, and repeat the
fault finding chart procedure or the procedure for
the fault that referred you to this test.
Are the low pressure circuit connections in order
and in good condition?Carry out the necessary repairs.
