These parameters are used so that the history of the last ten activations of the particle filter warning light are
known.
In Vdiag 18, 1C, 54:
Each parameter from PR784 to PR793 records the distance when the particle filter warning light comes on which
is associated with the appearance of DF312.
Each time the particle filter warning light comes on, the vehicle mileage is stored in the following parameter (PR+1).
When all ten parameters have a value other than zero, and the particle filter warning light comes on again, the
distance information for PR784 is cleared and replaced by the new value.
For other Vdiags:
Each parameter from PR784 DF312 record no. 1 to PR793 DF312 record no. 10 contains a record of the vehicle
mileage when the particle filter warning light comes on. The appearance of fault DF312 Speed request is
associated with each of these parameters.
PR784 to PR793 operate through successive copying (when the particle filter warning light comes on, the value of
PR784 is copied to PR785 DF312 record no. 2, the value of PR785 is copied to PR786 DF312 record no. 3 and
so on).
When there are more than ten records, the value of PR793 is deleted. The new mileage is allocated to PR784.
If none of the parameters between PR784 and PR793 is available in the sub-function, this means that no data has
been saved. The parameters appear in the sub-function when they have a value above zero.

PR1012WEIGHT OF SOOT AFTER REGENERATION
STATUS
DEFINITIONThis parameter indicates the weight in g of soot present in the particle filter following
regeneration.
NOTESThis parameter should be consulted after running SC017 Particle filter regeneration.
Conformity check: Engine stopped and ignition on, or engine running and engine coolant
temperature > 80°C without electrical consumers
If this parameter is less than 15 g, particle filter regeneration was successful.
If PR1012 is greater than 15 g, it is necessary to perform a second particle filter regeneration using command
SC017 Particle filter regeneration.
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.

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.
