STATUS
DEFINITIONACTIVE: This status indicates that the brake pedal is depressed.
INACTIVE: This status indicates that the brake pedal is released.
NOTESNote:
Statuses ET704 and ET705 must change specification at the same time. If they are
inconsistent, refer to the interpretation of fault DF228 Brake signal.
Conformity check with engine stopped and ignition on, or engine running, and engine coolant
temperature > 80°C
"ACTIVE"Brake pedal depressed.
A brake signal non-conformity may cause the engine to race during gear changes.
In the event of a fault, consult the interpretation of ET704 and ET705.
"INACTIVE"Brake pedal released.
A brake signal non-conformity may cause the engine to race during gear changes.
In the event of a fault, consult the interpretation of ET704 and ET705.

Conformity check: Engine stopped and ignition on, or engine running, and engine coolant
temperature > 80°C
This status indicates the recorded engine status in the event of a regeneration failure when driving:
NONE, + AFTER IGNITION, RUNNING, STOPPED.
Each STATUS between ET706 and ET715 corresponds to failed regenerations for which the mileage is recorded
by PR794 Stored regeneration failure No. 1 to PR803 Stored regeneration failure No. 10 (for example, PR797
Stored regeneration failure No. 4 is linked to ET709).
"RUNNING"If the STATUS is RUNNING, the regeneration failed because:
– the customer's driving did not generate enough heat,
– an engine management system component is defective.
"STOPPED"If the STATUS is STOPPED, the regeneration failed because the engine was
switched off.
+ APCPOWER LATCH
"NONE"No failed regeneration is present.

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.
