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.

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).

NOTESConditions for applying the fault finding procedure to a stored fault:
The fault is considered present when the engine is running.
Priorities when dealing with a number of faults:
– Deal with all the other faults before fault DF859
Special notes:
This fault is activated when the injectors have not been reset for 1800 miles
(3000 km).
Leave the vehicle to run at idle speed until the engine is warm.
When the engine is warm (PR064 COOLANT TEMPERATURE above 77°C), carry out the following test drive:
– Drive at a speed of up to 30 mph (50 km/h) and change into 5th gear.
– Stay in this gear and perform 8 accelerations from 30 mph (50 Km/h) to 54 mph (90 Km/h).
– At the end of driving: without switching off the ignition, allow the vehicle to run at idle speed for at least
10 minutes.
– Switch off the ignition, and wait 30 seconds.
– switch on the ignition, check that the fault is stored and clear the fault.

RZ001Fault memoryThis command is used for clearing the computer's stored
faults
RZ002EGR programming adaptivesUse this command when replacing the EGR valve (not
applicable to K9K796 Euro 2).
RZ004Pressure regulation adaptivesUse this command when simultaneously replacing the four
injectors and after replacing/retightening the accelerometer.
It enables you to reset the injector adaptives.
RZ005ProgrammingThis command enables you to reinitialise the entire computer
configuration.
AC001Preheating unitActivating this controls the preheating unit to test the heater
plug supply.
AC002EGR solenoid valveActivating this enables an audible check of the mechanical
operation of the EGR valve (not applicable to K9K796
Euro 2).
AC004Turbocharging solenoid valveActivating this enables an audible check of the operation of
the turbocharging solenoid valve.
AC005Cylinder 1 injectorActivating this enables an audible check of the injector on
cylinder 1.
AC006Cylinder 2 injectorRunning this allows you to you listen to the injector on
cylinder 2 when operating.
AC007Cylinder 3 injectorActivating this enables an audible check of the injector on
cylinder 3.
AC008Cylinder 4 injectorActivating this enables an audible check of the injector on
cylinder 4.

In this case, it may be the solenoid valve dynamic specification which is at fault (atmospheric pressure
resetting time). Final fault finding is carried out by measuring this specification on a special bench.
Check that solenoid valve casing does not have any splashes of fluid on it which may impede the breather (water,
engine oil, gearbox oil, brake fluid, coolant, mud, dust, or any other substance).
Instructions:
The solenoid valve must be set up 450 mm above the ground, in an area free from water, mud, or any other fluid.
Cleaning with a high pressure jet is forbidden.
Is there coolant present?
Is the solenoid valve subjected to significant fluctuations or impacts?
Instructions:
The solenoid valve must be correctly secured to its mounting.
Contact with the engine environment is forbidden.Follow the
recommendations below.
Check the turbocharger regulation control (no
partial jamming, etc.).Follow the recommendations below.
