STATUS DEFINITIONStatuses ET742 to ET751 correspond to the causes for the regeneration request. They
are connected to parameters PR816 Stored regeneration start No. 1 to PR825
Stored regeneration start No. 10 which contains the stored mileage of the vehicle at
the start of the regeneration (for example, PR745 Store regeneration start No. 4 is
related to ET709 Store regen.* request status No. 4).
NOTESSpecial notes:
For Vdiag 48:
These statuses should only be interpreted for ALP11 Particle filter warning light
comes on too frequently.
Conformity check with engine stopped and ignition on, or engine running, and engine coolant
temperature > 80°C
STATUS 1Request by weight of soot
Regeneration has been requested after the maximum weight of soot has been
reached and measured in the particle filter, without the particle filter warning light
coming on.

STATUS 2
Request by estimated weight of soot
Regeneration has been requested following an estimate of the maximum weight of
soot in the particle filter, without the particle filter warning light coming on.
STATUS 3Request by distance travelled
Regeneration has been requested because the distance travelled since the last
successful regeneration has reached the maximum authorised value (the particle filter
warning light has not illuminated).
STATUS 4Request by number of regeneration failures or weight of soot
This status corresponds to the appearance of DF312 Speed request.
This corresponds to the maximum number of failed regenerations or to the maximum
weight of soot in the particle filter, with illumination of the particle filter warning light.
AFTER REPAIRCarry out a road test, then check with the diagnostic tool.

PR002ALTERNATOR CHARGE
PARAMETER
DEFINITIONThis parameter indicates the charge value of the alternator in %.
NOTESSpecial notes:
Only perform these tests if the parameters do not correspond with the system
operation programming.
Conformity check with engine stopped and ignition on, or engine running, and engine coolant
temperature > 80°C
The alternator charge value varies according to the battery voltage.

PR005EGR VALVE OPENING SETPOINTS
PARAMETER
DEFINITIONThis parameter indicates a theoretical opening value for the EGR valve for optimum
engine performance.
NOTESSpecial notes:
Only perform these tests if the parameters do not correspond with the system
operation programming.
Conformity check with engine stopped and ignition on
The EGR valve theoretical opening value for operation with the engine stopped and ignition on is:
-10 Conformity check with engine running, engine coolant temperature > 80°C
The theoretical EGR valve opening value for operation with the engine running and engine coolant temperature
>80°C is 10 < PR005 < 40%
