STATUS1Request by weight of soot
Regeneration was requested based on the measurement of maximum soot weight in
the particle filter, without the particle filter warning light coming on.
STATUS2Request by estimated weight of soot
Regeneration was requested based on an estimation of maximum soot weight in the
particle filter, without the particle filter warning light coming on.
STATUS3Request by distance travelled
Regeneration has been requested after a maximum distance has been travelled
since the last successful regeneration without the particle filter warning light
coming on.
STATUS4Request 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 regeneration or to the maximum
weight of soot in the particle filter, with the particle filter warning light coming on.

COOL*: Cooling
ET776RECIRCULATED EXHAUST GAS COOL* SETPOINTS
STATUS
DEFINITION
ACTIVE: This status indicates that the recirculated exhaust gas cooling setpoint
is active.
INACTIVE: This status indicates that the recirculated exhaust gas cooling setpoint
is not active.
NOTESNone.
Conformity check: Engine stopped and ignition on and Engine running and engine coolant
temperature > 80°C
This status gives a setpoint for status ET587 Recirculated exhaust gas cooling. This programming changes
depending on the computer.
In the event of a fault, see the interpretation of faults DF209 EGR valve position sensor circuit and DF647 EGR
valve position regulation.

Fast plugs
Status ET781 is STATUS 2 if the heater plugs fitted to the engine have white rings,
otherwise run command SC036 and select HEATER PLUGS (see Interpretation of
commands).
STATUS3NOT DEFINED
Status ET781 is STATUS 3 when the heater plugs are not configured in the injection
computer.
To determine the heater plugs fitted to the engine, visually check the colour of the
plug rings, then run command SC036 and select HEATER PLUGS
(seeInterpretation of commands).
