REPLACING THE INJECTORS
The system can be configured with the diagnostic socket using the diagnostic tool.
The C2I parameters must be replaced after replacing an injector/injectors.
To do this, enter the C2I again into the injection computer using the following commands:
- VP001 Cylinder 1 injector for the cylinder 1 injector (cylinder on flywheel end),
- VP002 Cylinder 2 injector for the cylinder 2 injector,
- VP003 Cylinder 3 injector for the cylinder 3 injector,
- VP004 Cylinder 4 injector for the cylinder 4 injector.
It is also possible to enter all four C2I using command SC002 Enter injector codes.
REPLACING THE HIGH PRESSURE PUMP
PROCEDURE
– Switch on the ignition and use the diagnostic tool to re-establish dialogue with the injection computer.
– Use command AC212 New pump chamber filling.
– Operate the starter (Important: starting the engine may take 20 seconds due to the time taken to reprime the
pump).
– After the engine has started, refer to ET637 Fill new pump chamber and check that it is Done; if not, repeat the
starting procedure. Note:
C2I (individual injector correction) is a calibration carried out in the factory on each injector to adjust the flow
of each injector precisely.
The correction values are written on a label affixed to each injector, then entered in the computer which can then
actuate each injector by taking account of their manufacturing variations.
Only after simultaneously replacing at least three injectors, reset the injector adaptives, using command RZ004
Pressure regulation adaptives.
IMPORTANT
When reprogramming the computer, only carry out the following procedure after running command AC028
Static test (see Computer reprogramming operation).

SETTINGS
VP001: Cylinder 1 injector
VP002: Cylinder 2 injector
VP003: Cylinder 3 injector
VP004: Cylinder 4 injector
These commands enable you to manually write the calibration code marked on the injector.
Use these commands after replacing the injector or replacing or (re)programming the computer, when
command SC001 Write saved data does not work.
VP010: Write VIN.
This command enables the vehicle VIN to be entered into the computer.
Use this command each time the computer is replaced or (re)programmed.
VP013: Lock injector control.
This command disables electrical actuation of the injectors, for carrying out the compression test.
SPECIAL COMMANDS
SC001: Write saved data.
Use this command after replacing or (re)programming the computer (if the data were saved using
command SC003 Save computer data).
SC002: Enter injector codes.
This command enables you to manually write the calibration code marked on the injectors.
Use this command after replacing the injectors.
SC003: Save computer data.
This command saves the computer operating data, C2I (individual injector correction) parameters
and engine programming adapters.
Use this command before replacing or (re)programming a computer.

Special notes:
If fault DF007 is present, the engine stops and restarting is impossible.
Level 2 warning light comes on.
Use the Wiring Diagrams Technical Note for Logan, Sandero, Duster, Thalia 2/
Symbol 2 or Kangoo VLL.
Check the connection and condition of the rail pressure sensor connector, component code 1032.

If the connectors are faulty and if there is a repair procedure (see Technical Note 6015A (Renault) or Technical
Note 9804A (Dacia), Electrical wiring repair, Wiring: Precautions for repair), repair the connector, otherwise
replace the wiring.
Check for + 5 V on connection 3LX of the rail pressure sensor, component code 1032.
Check for earth on connection 3LZ of the rail pressure sensor, component code 1032.
If the connection(s) are faulty and if there is a repair procedure (see Technical Note 6015A (Renault) or
Technical Note 9804A (Dacia), Repairing electrical wiring, Wiring: Precautions for repair), repair the wiring,
otherwise replace it.
Check the insulation, continuity and the absence of interference resistance on the following connections:
●3LX between components 120 and 1032,
●3LY between components 120 and 1032,
●3LZ between components 120 and 1032.
If the connection(s) are faulty and if there is a repair procedure (see Technical Note 6015A (Renault) or
Technical Note 9804A (Dacia), Repairing electrical wiring, Wiring: Precautions for repair), repair the wiring,
otherwise replace it.
If the fault is still present, the rail pressure sensor is faulty, replace the rail (see MR 388 (Logan/Sandero) or MR
451 (Duster), MR 423 (Thalia 2/Symbol 2) or MR 374 (Kangoo VLL), Mechanical, 13B, Diesel injection,
