PARAMETER
DEFINITIONThese parameters are shown in Km.
NOTESSpecial notes:
These parameters must only be interpreted for DF312 Speed request if it is present
or stored.
These parameters exist only in Vdiag48.
Conformity check with engine stopped and ignition on, or engine running, and engine coolant temperature
> 80°C, without electrical consumers
In the event of a fault, consult the interpretation of fault DF312 Speed request.
These parameters are used for looking up the history of the last ten particle filter warning light activations
Each parameter from PR784 to PR793 contains a record of the vehicle mileage when the particle filter warning
light illuminates. 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, the value of PR785 is copied to PR786 and so on).
When there are more than ten records, the value of PR793 DF312 record no. 10 is cleared. 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.

These parameters are used so that the history of the last ten failed regenerations when driving is known.
Each parameter between PR794 and PR803 contains the vehicle mileage when particle filter regeneration fails
when driving. each parameter relates to an engine status. They are recorded simultaneously (for example PR797
Regeneration failure record No. 4 is associated with ET709 Engine status record no. 4).
PR794 to PR803 operate through successive copying (when regeneration fails whilst driving, the value of PR794
is copied to PR795, the value of PR795 is copied to PR796 and so on).
When there are more than ten records, the value of PR803 Regeneration failure record no. 10 is overwritten.
The new mileage is allocated to PR794.
If none of the parameters between PR794 and PR803 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.

Each parameter from PR816 to PR825 records the mileage at the start of particle filter regeneration, for which the
request status is recorded by ET742 Stored reg.* request status no. 1 to ET751 Stored reg.* request status
no. 10 (for example PR819 Stored regeneration start no. 4 is associated with ET745 Stored reg. request
status no. 4).
Each time a new regeneration is started when driving, the vehicle mileage is recorded in PR816, as well as its
status in ET742 Stored reg.* request status no. 1.
PR816 to PR825 operate through successive copying (when regeneration starts, the value of PR816 is copied to
PR817, the value of PR817 is copied to PR818 and so on).
When there are more than ten stored items, the value of PR825 Regeneration start record no. 10 is overwritten.
The new mileage is allocated to PR816.
If only the parameter PR816 Regeneration start record no. 1 is available in the sub-function and it has no value,
this indicates that no record was made.
If a record has been made, it will have a value above zero.
