COMPUTER REPLACEMENT, PROGRAMMING AND REPROGRAMMING OPERATIONS
The system can be programmed via the diagnostic socket using the diagnostic tool (see Technical Note 3585A
Computer programming and reprogramming procedure and Technical Note 9869A Computer programming
and reprogramming procedure and following the instructions provided by the diagnostic tool).
Before removing the computer in After-Sales, save the computer data using the diagnostic tool by running
command SC003 Save computer data. This command saves the following information:
–C2I parameters (individual injector correction) and engine parameters,
–Measuring system information,
–Injection system reset data. IMPORTANT
– Switch on the diagnostic tool (mains or cigarette lighter supply).
– Connect a battery charger.
– Switch off all electrical consumers (lights, interior lights, air conditioning, radio/CD, etc.).
– Wait for the engine to cool (engine coolant temperature below 60°C and air temperature below 50°C).
IMPORTANT
It is not possible to try an injection computer coming from the Parts Department because it will no longer be
possible to use it on another vehicle.

After the computer has been programmed:
– Switch off the ignition.
– Switch on the ignition again and use the diagnostic tool to carry out the following steps:
– Use command SC001 Write saved data to restore the C2I and the engine adaptive programming.
– Run command VP010 Write VIN.
– Run command AC028 Static test.
– Run command AC154 Low speed fan assembly to test the operation of the 1st speed fan assembly.
– Run command AC153 High speed fan assembly to test the operation of the 2nd speed fan assembly.
– Run command AC250 Heating resistor 1 relay to test the operation of passenger compartment heating resistor 1.
– Run command AC251 Heating resistor 2 relay to test the operation of passenger compartment heating resistor 2.
– Run command AC100 Stop electrical consumer inhibition.
– Run command AC212 Fill new pump chamber.
– Run the starter motor without releasing the key until the engine starts (the pump reprime time until the engine starts
can be up to 20 seconds).
– After the engine has started, refer to ET637 Fill new pump chamber and check that it is Done; if not, repeat the
starting procedure.
–Stop the engine, switch off the ignition (to initialise the computer) and wait 30 seconds.
– After injection system programming, stored faults may appear in other computers.
– If DF1083 Water in diesel fuel warning light circuit appears in the injection computer: on a vehicle fitted with
a water in diesel fuel warning light, perform the fault finding operations described in DF1083 then run command
AC028 Static test; on other vehicles, do not deal with the fault.
– Clear the computer memory RZ001 Fault memory.
IMPORTANT
AFTER A (RE)PROGRAMMING OPERATION, DO NOT DISCONNECT THE BATTERY FOR AT LEAST
30 MINUTES (to carry out other work on the vehicle).
Note:
If commands SC003 Save computer data and SC001 Write saved data have been lost or do not work, after
programming the computer, enter the C2I for each injector manually by reading the C2I on each injector (see
Replacing the injectors).

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).

REPLACING THE EGR VALVE
If the EGR valve is replaced, program the new valve's offset position.
Switch on the ignition and use the diagnostic tool to carry out the following:
– run command RZ002 EGR adaptives to clear the old offset using the EGR programming deletion procedure.
– Special feature of the K9K796 Euro 2 engine (Indonesia): The EGR solenoid valve is present on the vehicle, but
not used. It always remains closed. It must not be replaced on this vehicle (unless there is a mechanical fault).
IMPORTANT
Do not use this command if the valve is not new.

NOTESSpecial notes:
If fault DF001 is present, the preheating time is greater than 10 seconds and the
engine fan switches on at low speed (Fan assembly 1). If there is a fault on Fan
assembly 1, then Fan assembly 2 switches on (on vehicles fitted with air conditioning).
Use the Wiring Diagrams Technical Note for Logan, Sandero, Duster, Thalia 2/
Symbol 2 or Kangoo VLL.
Check the condition and connection of the coolant temperature sensor connector, component code 244.
Check the connection and condition of the injection computer connector, component code 120.
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 connectors, otherwise
replace the wiring.
Check the insulation, continuity and the absence of interference resistance on the following connections:
●3C between components 244 and 120,
●3JK between components 244 and 120,
●M (or NH) of component 244,
●42A between components 244 and 247.
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.
Measure the resistance of the coolant temperature sensor between connections 3JK and 3C of component 244.

Conditions for applying the fault finding procedure to a stored fault:
The fault is present when the starter motor is operating or the engine is running at idle
speed.
Check the connection and condition of the engine speed sensor connector, component code 149.
Check the connection and condition of the injection computer connector, component code 120.
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 that the engine speed sensor is correctly fitted to the engine.
Check the insulation, continuity and the absence of interference resistance on the following connections:
●3BL between components 120 and 149,
●3BG between components 120 and 149.
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.
Measure the resistance of the engine speed sensor between connections 3BG and 3BL of component 149.
If the resistance of the engine speed sensor is not between 510  < X < 850  at 20°C, replace the sensor (see
