VALIDATING THE REGENERATION PROCESS:
At the end of regeneration, a message appears to announce whether the regeneration was successful:
•Particle filter regeneration finished:
Consult PR1012 Weight of soot after regeneration. If this parameter is less than 15 g, the particle filter
regeneration was successful. If PR1012 is greater than 15 g, it is necessary to carry out a second particle filter
regeneration using the diagnostic tool and run command SC017.
IMPORTANT:
Before performing a second After-Sales regeneration of the particle filter, the engine must be allowed to cool
down for 2 hours with the bonnet open.
Do not carry out an engine oil change before a second After-Sales regeneration.
For Vdiag 28 and 62:
Change the engine oil if requested by a message on the instrument panel.
For the other VDiag:
Consult PR848 Number of regeneration failures. If PR848 is greater than 3, change the engine oil.
Particle filter too full - replace the particle filter: regeneration has failed. The weight of soot in the particle filter
is so great that it is creating a counter pressure. Deal with any faults that appear or replace the particle filter. Run
command SC036: Reinitialise programming and select After particle filter replacement.
For Vdiag 28 and 62:
Change the engine oil if requested by a message on the instrument panel.
For the other Vdiags:
Consult PR848 Number of regeneration failures. If this parameter is greater than 3, it is essential to
change the engine oil.

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.

NOTESSpecial notes:
this command enables you to reinitialise the entire computer configuration according to
the vehicle.
Command RZ005 reconfigures the computer.
If the computer does not have any configuration data, use command RZ005 to enter the vehicle options:
– air conditioning,
– Passenger compartment heating resistor,
– cruise control/speed limiter.
These options are detected by the computer even if command RZ005 is not used.
The computer is configured as soon as the one of the vehicle's optional system components is operated.

2. If at least one of these values is X < - 5 mg/stroke
– Check the valve clearance.
– Check the level and condition of the engine oil.
– Remove the injector with the largest adjustment.
– If there is contamination via the diesel, check the condition of the cylinder concerned (cylinder, piston, valves).
– Replace the injector* concerned.
– See paragraph Part C, for confirmation of the fault finding.
3. If at least one of these values does not stabilise (20 seconds after starting):
– Check the low pressure circuit using Test 3 Low pressure circuit test.
– Check the fuel is correct by carrying out Test 12 Diesel fuel conformity check.
See paragraph Part C of Test 10, for confirmation of the fault finding.
After replacing an injector, follow the injector code programming procedure (see Replacement of components),
run SC036 Reinitialise programming and select the number of the injector replaced.
IMPORTANT:
When removing / refitting injectors, follow the cleanliness and safety instructions (see MR 395 (Laguna II ph2),
