If the types of regeneration that are performed automatically (while the machine
is operating) are bypassed or not allowed to complete before shutting off the
engine, soot will continue to accumulate in the soot filter. When enough soot
accumulates, the engine ECU will generate an engine fault to prompt a parked or
recovery regeneration. In addition to an engine fault appearing on the InfoCenter,
the engine output power will be reduced.
Fault Code
Ash is a result of the regeneration processes. The lighter ash is discharged
through the exhaust system, while the heavier ash collects in the soot filter.
When enough ash accumulates in the soot filter, the engine ECU will generate an
engine fault to prompt servicing the DPF. In addition to an engine fault appearing
on the InfoCenter, the engine output power and speed will be reduced.
