Fuel Heater
A fuel heater is available and installed in the fuel filter assembly.
The heater warms the supply fuel to prevent waxing during cold
conditions.
Idle Shutdown Timer (IST) Federal - Optional or California -
Standard
IST allows the Engine Control Module (ECM) to shut down the
engine during extended engine idle times.
Beginning with the 2008 Model Year engine, all Navistar
®
MaxxForce
engines certified for sale in the state of California
will conform to mandatory California Air Resources Board
(CARB) Engine Shutdown System (ESS) regulations.
All (non-California) Federal Navistar
can have idle time that can be programmed from 2 to 120
minutes.
For further information, see Engine Shutdown (page 51).
Power Take Off (PTO)
In Cab Power Take-off (PTO) Control
The in cab engine speed control feature, commonly referred to
as Power Take-off (PTO), allows the operator to set and maintain
a constant engine speed without using the accelerator pedal. It
is commonly used for powering auxiliary devices.

Customer programmable parameters within the Engine Control
Module (ECM) provide in-cab engine speed control related
options that can be adjusted to suit the customer's needs.
Choosing whether the operator is allowed to increase engine
speed using the accelerator pedal with out disengaging the PTO
is an example.
Remote Engine Speed Control (RESC)
RESC, commonly referred to as remote PTO, allows the operator
to set and maintain engine speed without using the accelerator
pedal. It is commonly used for powering auxiliary devices.
When control over engine speed is required from outside the
vehicle's cab, remote mounted switches must be used to turn on
PTO engine speed control and select the desired engine speed.
Engine speed can be ramped up and down with RESC similar
to the way the in-cab PTO feature works. However, the RESC
feature includes two additional switches (remote preset and
remote variable) which allow the operator to choose the mode
of engine speed control operation.
Customer programmable parameters within the ECM provide
RESC options that can be adjusted to suit the customer's
needs. Choosing whether a remote throttle pedal is used for
PTO operation is an example.
Oil Pan Heater
The oil pan heater warms engine oil in the pan to ensure optimum
oil flow.
