D - PARAMETER MEASUREMENTS
Particle filter state
This shows the status of the particle filter (regenerated, intermediate zone,
loaded, overloaded, clogged or punctured).
Particle filter differential pressure (difference between inlet/outlet pressure).
This parameter corresponds to the pressure difference between the inlet and the
outlet of the particle filter.
This value is similar to the "filter state" parameter.
The pressure differential varies depending on the vehicle mileage and driving
conditions.
Regeneration assistance state
This parameter states whether regeneration assistance is in progress (active or
not active).
Total amount of additive injected
The total amount of additive injected since the additive tank was last refilled.
Average distance of last 5 regenerations - distance travelled since
regeneration
Refer to the operating phases - particle filter section.
E - FORCED REGENERATION
Before a particle filter is cleaned, forced regeneration allows any remaining soot
to be removed and facilitates cleaning of cerine deposits.
F - REINITIALISING THE TOTAL ADDITIVE QUANTITY
After replacing or cleaning a particle filter, the total amount of additive must be
reset in the additive ECU (calculation of the injection ECU cartographic maps).
