Possible cause of fault
◆ Diesel particulate fil-
ter overloaded, e.g.
due to excessive
short-distance driving
◆ The system was in
thermal management
mode for longer than
for more than 100 op-
erating hours, or the
operating hour ratio
between normal
mode and thermal
management mode is
higher than 25% (as
of 25 operating hours
in thermal manage-
ment mode after last
service regeneration)
Possible cause of fault Possible effects
◆ Fault in data wires
◆ No communication
◆ This fault path is used
for indicating an ex-
cessive soot loading
of the diesel particu-
late filter. The counter
in the diagnosis ex-
tract describes, how
often there was a die-
sel particulate filter
loading > 2nd alarm
threshold (soot load-
ing of 26 g). After the
work day has been
completed, a service
regeneration must be
performed on the die-
sel particulate filter.
◆ Engine will not start
◆ Torque limiting
◆ Gearbox limp mode
◆ No ACC increase
◆ None
◆ No ACC increase
Fault remedy
◆ After the service re-
generation, the en-
gine oil must be
changed. There may
be a fault in the fol-
lowing components:
EGR cooler, air mass
meter, turbocharger/
charge pressure, in-
jection quantities, in-
jectors (IMA-code),
air filter, leak in
charge air system,
pressure differential
sender with hoses.
