The Check Engine Indicator displayed with a
steady Engine Shutdown Indicator shows there
are one or more severe faults with the engine
electronic management system and the engine
is operating at reduce power.
The Check Engine Indicator displayed with a
flashing Engine Shutdown Indicator shows
there are one or more very severe faults with
the engine electronic management system
and the engine should be shut down as soon
as possible (the engine may automatically
shutdown in some conditions).
The Check Engine Indicator displayed with a
flashing Low DEF Level Indicator shows the DEF
tank is critically low and the engine is operating
at reduced power; add DEF as soon as possible.
The Check Engine Indicator displayed with
a steady Engine Shutdown Indicator and a
flashing Low DEF Level Indicator shows the
DEF tank is empty and the engine is operating
at reduced power or limited to idle; add DEF
immediately.
The Check Engine Indicator displayed with the
Exhaust System Cleaning Indicator shows that
a manual regeneration of the exhaust system
is required and the engine is operating at
reduced power.
ENGINE SHUTDOWN INDICATOR
A steady Engine Shutdown Indicator displayed
with the Check Engine Indicator shows there

EXHAUST AFTER TREATMENT SYSTEM
The engine control system monitors and
manages the exhaust after treatment
system. The system works to reduce soot
loading. If excessive soot loading is detected,
the engine control system will enter an
automatic regeneration mode by elevating
the exhaust temperature. The forklift can be
operated normally during this regeneration
as long as there are no issues with the high
exhaust temperature. If the forklift is being
operated in an area where the high exhaust
temperature could cause problems, such as
near combustibles, the automatic regeneration
may be temporarily disabled by pressing the
Enter button or Regen soft button to bring up
the After Treatment Control menu and then
pressing the Regen Mode Disable soft button.
If the automatic regeneration is unable to
keep the soot loading under control, a manual
regeneration will be requested. If a manual
regeneration is not performed and the soot
loading becomes serious, the engine power
will be reduced and a manual regeneration is
required. The forklift must not be operated
during a manual regeneration.
