SPECIFICATION OF
THE PARAMETERSThese parameters indicate the regeneration failure record in miles (km).
NOTESSpecial note:
Check the interpretation of these parameters only on ALP21 Particle filter warning
light illuminated.
Conformity check with the engine stopped and the ignition on, or the engine running and the engine
coolant temperature > 80°C
these parameters are used so that the history of the last ten regeneration failures when driving are known.
Each parameter from PR794 to PR803 records the distance when regeneration fails and the engine status is
recorded by ET706 Stored engine status no. 1 to ET715 Stored engine status no. 10 (for example: PR797
Stored regeneration failure no. 4 is associated with ET709 Stored engine status no. 4).
The value is saved in the next parameter (PR+1) each time a new save is performed.
The distance of the last regeneration failures when driving are recorded in the other available parameters
(distance information in PR794 is recopied in PR795 and distance information in PR795 is recopied in PR796 and
so on).
When all ten parameters have a value other than zero, and a failed regeneration occurs when driving, the
distance information for PR794 Regeneration failure record No.1 is erased and replaced by the new value.
AFTER REPAIRDeal with any faults displayed by the diagnostic tool.
Clear the computer memory.
Carry out a road test followed by another check with the diagnostic tool.

PARAMETER
DEFINITIONThese parameters indicate the particle filter warning light record in miles (km).
NOTESSpecial note:
Check the interpretation of these parameters only on ALP21 Particle filter warning
light illuminated.
Vdiag 45 and 49 only.
Conformity check with the engine stopped and the ignition on, or the engine running and the engine
coolant temperature > 80°C
these parameters are used so that the history of the last ten illuminations of the particle filter warning light are
known.
Each parameter from PR836 to PR845 records the distance at which the particle filter warning light illuminated
and this is associated with the appearance of DF311 Number of regeneration failures exceeded.
The value is saved in the next parameter (PR+1) each time a new save is performed.
The distances of the last illumination of the particle filter warning light are saved in the other available parameters
(the distance information in PR836 is recopied to PR837 and the distance information in PR837 is recopied to
PR838 and so on).
When all ten parameters are not zero and the particle filter warning light illuminates again, the distance
information of PR836 Particle filter warning light record no. 1 is erased and replaced by the new value.
AFTER REPAIRDeal with any faults displayed by the diagnostic tool.
Clear the computer memory.
