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.
