SC001WRITE SAVED DATA
NOTESTo use this command, first save the data with the SC003 Save computer data
command.
The writing is carried out after the computer has been reprogrammed or replaced.
Engine stopped.
In the diagnostic tool, select scenario SC001.
Note:
If no files have been saved before, a write error appears when command SC001 is activated.
Validating this command writes the data saved using command SC003 Save computer data.
The data is as follows:
– vehicle-specific idling,
– injector codes,
– various offsets for components, EGR, damper valve,
– options available on the vehicle and generated by the computer.
This data will configure the computer and will prevent:
– engine malfunction after reprogramming or replacing the computer,
– incorrect interpretation of the information provided by the diagnostic tool.

SC036REINITIALISE PROGRAMMING
NOTESThis command is used to reset the computer parameters according to the type of
operation or component repaired or replaced from the following list:
– the injectors
– the EGR valve,
– the damper valve,
– after particle filter replacement,
– after particle filter regeneration using the CLIP diagnostic tool,
– after injection computer replacement with no backup option,
– the heater plugs.
Ignition on and engine stopped.
To run this command, select scenario SC036 in the diagnostic tool.
Procedure to be followed:
– on the main screen, select the component to reinitialise after an operation (removal - refitting, regeneration or
replacement of the component),
– select YES then OK to begin reinitialisation,
–Important: when reinitialising injectors, do not forget that cylinder no. 1 is located at the timing end,
– select end on the configuration completed screen to return to the main screen,
– end of operation.
