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).

Check the insulation, continuity and the absence of interference resistance on the following connections:
●3B between components 120 and 799,
●3FB (or 3FBA) of component 799,
●NH of component 799.
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 air flow sensor to ensure that it is between:
41255 < X < 47492 at - 40°C,
14260 < X < 16022 at - 20°C,
5497 < X < 6050 at 0°C,

If the value is not correct, replace the air flow sensor (see MR388 (Logan/Sandero), MR451 (Duster),
Mechanical, 12A Fuel mixture, Air flowmeter: Removal – Refitting).
If the fault is still present, replace the air flowmeter (see MR388 (Logan/Sandero), MR451 (Duster), Mechanical,
12A Fuel mixture, Air flowmeter: Removal – Refitting).
If the fault is still present, contact the Techline.
