Soot Accumulation
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 addi-
tion to an engine fault appearing on the InfoCenter, the engine output power will be reduced.

Ash Accumulation
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.
