STATUS1
Request by weight of soot
Regeneration has been requested following measurement of the maximum weight of
soot in the particle filter, without the particle filter warning light coming on.
STATUS2Request 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.
STATUS3Request by distance travelled
Regeneration has been requested as the distance travelled since the last successful
regeneration has reached the maximum authorised value (the particle filter warning
light has not come on).
STATUS4Request by number of failed regenerations or soot weight
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 the particle filter warning light coming on.
* REGEN: Regeneration
AFTER REPAIRCarry out a road test, then check with the diagnostic tool.

ALTERNATOR CHARGE
PARAMETER
DEFINITIONThis parameter indicates the alternator charge value 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.
AFTER REPAIRCarry out a road test followed by a check with the diagnostic tool.

EGR VALVE OPENING VALUE REQUIRED
PARAMETER
DEFINITIONThis parameter indicates a theoretical opening value for the EGR valve giving 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 < PR005 < 0%.
In the event of a fault, refer to the interpretation of fault DF272 EGR control circuit.
Conformity check with the engine running and engine coolant temperature > 80°C.
The theoretical EGR valve opening value for operation with the engine running and the engine coolant
temperature > 80°C is 10 < PR005 < 40%.
If there is a fault, refer to the interpretation of fault DF272 EGR control circuit.
AFTER REPAIRCarry out a road test, then check with the diagnostic tool.
