How to Read This Document
The programming guide is divided into several sections; each section represents a
programmable feature offered with the engine. The sections are divided into
subsections to organize the details of each feature: Overview, Standard Feature,
Feature Options, Orderable Feature & Options, Programmable Parameters,
Nonprogrammable Parameters, ON/OFF Requirements, Activate/Deactivate
Requirements, and Additional Information.
Overview
The feature is summarized focusing on the customer benefits, options, and
functionality.
Standard Feature
This subsection provides details of the stock or standard feature available with the
engine.
Feature Options
This subsection provides details of the optional features available with the engine.
Orderable Feature Options & Sales Codes
Features and options that require action during the ordering or the aftermarket
parameter setting change processes are detailed in a reference table. The table is
divided into three columns: Feature and Peterbilt/Kenworth Sales Codes. The
“Feature” column identifies the feature. The “Sales Code” columns provide the
division-specific sales code used to identify a feature option during the ordering
process.

Programmable Parameters
Some features have individual parameters that are customizable; the details of these
programmable parameters are given in a reference table. The reference table is
divided into three columns: “Parameter Name,” “Number,” and
“Min/Max/Default/Unit”. The “Number” column references a code number to identify
the parameter during the ordering or the aftermarket parameter setting change
processes. The “Min/Max/Default/Unit” column defines the minimum and maximum
values of the parameter setting. If the parameter is not altered during specification of
the vehicle, the default setting is delivered from the factory. The units associated with
a parameter are labeled after the value of the parameter.

MIN = Value (Unit)
MAX = Value (Unit)
DEFAULT = Value (Unit)
Nonprogrammable Parameters
Unchangeable parameters, also known as nonprogrammable parameters, are used
to assist in the explanation of a feature. A reference table is provided which is
divided into two columns: “Parameter Name” and “Default/Unit”. The “Parameter
Name” column identifies the parameter. The “Default/Unit” column defines the default
or standard value and unit associated with it.
Parameter Name
Default/Units
Parameter Name
DEFAULT = Value (Unit)
ON/OFF Requirements
To define when a feature is enabled/ON or disabled/OFF, a reference table is used
to detail the required conditions. The table is divided into two columns: ON and OFF.
In each column, there is a list of conditions that must be met for the feature to be ON
or OFF. In addition, both columns include a stipulation of “All” or “Any” in
parentheses. “All” indicates that every condition listed in the column is required to
turn the feature ON or OFF. “Any” indicates that only one of the conditions listed in
the column is required to turn the feature ON or OFF.

Engine Ratings
Overview
The engine rating states the peak power and torque of the engine. The engine is
available with several power ratings, allowing the engine to provide the correct
amount of power to complete the job while limiting the torque within driveline
component limitations. All power ratings are programmable without changing
hardware on the engine; however, increasing the power rating may put main
driveline components at risk for premature wear or damage. Three of the ratings are
available with multi-torque; these ratings are identified by the MT in the option name.

Maximum Accelerator Pedal Vehicle Speed (N162) defines the maximum operating
governed speed of the vehicle when Cruise Control and the Vehicle Speed Limiter
are not active.
The High Exhaust System Temperature (HEST) warning indicator allows the engine
to inform the operator when the exhaust temperature exceeds HEST Warning
Temperature Activation Limit and the vehicle speed is less than Minimum Vehicle
Speed for High Exhaust Temperature Lamp (N065).
Fuel Density (N051) allows the customer to reprogram the engine controller with a
fuel density that more precisely represents the local fuel variation used in their
vehicles, which will improve the accuracy of the controller’s calculated fuel economy.

Engine Idle Shutdown Timer (EIST)
Overview
The engine Idle Shutdown Timer (EIST) is a valuable tool fleet owners may use to
impose limits on engine idling time to improve overall fuel economy. The EIST has
several customizable options to meet the needs of any application. EIST may be
overruled by fuel temperature or engine coolant and oil temperature for uninterrupted
engine warm-up intervals and allows for separate timer intervals dependent on the
engagement of the parking brake. EIST may also be configured with an independent
timer or disabled completely while the engine is in Power Take-Off (PTO) mode.
Standard Feature

EIST

EIST Low Battery Voltage Overrule
EIST initiates when engine speed is at idle, the vehicle is stationary, and the
accelerator pedal is motionless or not depressed. Within the standard feature, there
are many programmable parameters:

Timer Durations and Enablement Conditions

Coolant, Oil, and Fuel Temperature Overrule

Programmable resets
Idle Time With Parking Brake Set (N187) specifies the timer duration until the engine
shuts down while the parking brake is engaged. Enable EIST When the Parking
Brake is Not Set (N192) allows the EIST to function when the parking brake is not
set. The timer duration may be specified by Idle Time with Parking Brake Not Set
(N188). Once the timer has expired, a warning message in the truck’s driver display
PEC017
12/19/2016
Page 12 of 90
will indicate that shutdown is imminent. Shutdown Timer After EIST Warning (N194)
determines the duration of the idle shutdown timer warning before the engine is shut
down. Allow Idle Timer Reset During Shutdown Timer (N178) will only allow the
driver to reset the idle shutdown timer during the shutdown timer warning period
Otherwise, the driver may reset the idle timer at any time by performing one of the
programmable reset conditions.
Temperature Overrules are available to allow the engine to idle while coolant, oil and
fuel temperatures are below calibrated settings.
Programmable Resets are signals from equipment on the vehicle that the operator
actuates. The reset can be turned ON or OFF. If the reset is ON when the equipment
is actuated, the EIST counter will restart. Programmable resets may only occur once
the operator has received notification of an impending shutdown on the driver
display. For example, when the EIST is set to 5 minutes with the accelerator pedal
reset ON and the vehicle idling for 4 minutes, a message of an impending shutdown
will appear on the driver display and an actuation of the accelerator pedal will reset
the timer and delay the engine’s shutdown for another 5 minutes (total idle time is 9
minutes). The following is a list of programmable reset conditions:

Accelerator Pedal as Idle Timer Reset Condition (N197)

Service Brake as Idle Timer Reset Condition (N198)

Clutch Pedal as Idle Timer Reset Condition (N199)

Parking Brake as Idle Timer Reset Condition (N179)

Engine Load as Idle Timer Reset Condition (N190)
Feature Options

Ambient Air Temperature Overrule

Engine Load Overrule

Engine Idle Shutdown Timer in PTO Mode
Ambient Air Temperature Overrule allows the engine to maintain operation without
shutdown when the temperature is above Idle Timer Maximum Ambient Temperature
Before Override (N184) or below Idle Timer Minimum Ambient Temperature Before
Override (N185).
EIST Engine Load Overrule allows the engine to maintain operation without
shutdown when the engine load is above Engine Load Required to Reset Idle Timer
(N183). Engine Load as Idle Timer Overrule Condition (N191) is only available when
Engine Load as Idle Timer Reset Condition (N190) is turned OFF. This feature is not
available with EIST in PTO Mode.
EIST may be configured to operate while the engine is in PTO Mode, and the timer
duration may be set with Engine Idle Time in PTO Mode (N186). The same
conditions must be met for the EIST to shutdown the engine.

Fast Idle Control (FIC)
Overview
The Fast Idle Control (FIC) functionality allows adjustment of engine idle speed
within preprogrammable limits. This allows the driver to adapt to changing engine
speed requirements. For example, the operator can raise engine speed for faster
engine warm-up on a cold day. Raising the idle can improve HVAC performance in
extreme conditions while parked, and may be helpful for other service operations
such as charging the batteries or air system. Fleet managers may find that altering
some of the FIC settings may yield better fuel economy when the application
requires extended idle operations. The FIC module allows a fleet owner to set limits
in order to enhance overall operating economy. FIC is a standard feature of the
engine, but can be disabled to ensure that engine idle speed cannot be altered.
The default FIC settings are useful for the majority of applications, so modifications
of the default settings typically are not necessary. Before changing the default
parameters, it is strongly recommended to consult the customer and/or body builder
to determine the specific vehicle application.
Standard Feature

FIC
FIC becomes active and allows the operator to control the engine speed with the
Set/Accel and Resume/Decel switches when all of the following conditions are met:

The Cruise Control switch is in the ON position

The vehicle is stationary

The transmission is in neutral

The parking brake is set
FIC will be overruled if the accelerator pedal request exceeds the FIC request, at
which point the accelerator pedal will control engine speed. FIC will automatically
deactivate if the clutch pedal or the service brake pedal are depressed.
The Set/Accel switch allows the operator to increase the engine speed. When FIC is
active and the Set/Accel switch is pressed, the engine speed will increase by
Increase Engine Speed w/ Set/Accel Switch Bump (N107). When FIC is active and
the Set/Accel switch is pressed and held, the engine speed will increase at Rate of
Engine Speed Increase when Set/Accel Switch Held (N103).
The Resume/Decel switch allows the operator to decrease the engine speed. When
FIC is active and the Resume/Decel switch is pressed, the engine speed will
decrease by Reduce Engine Speed w/ Resume/Decel Switch Bump (N105). When
FIC is active and the Resume/Decel switch is pressed and held, the engine speed
will decrease at Rate of Engine Speed Decrease when Resume Switch Held (N104).

Cruise Control (CC)
Overview
The Cruise Control (CC) functionality allows the operator to set a target vehicle
speed and then adjust it within programmable limits. This allows the driver to adapt
to changing vehicle speed requirements. For example, the operator can increase or
decrease speed by briefly pressing or pressing and holding the Cruise Control
switches on the dashboard or steering wheel. The vehicle must be within the
programmed limits to activate and maintain Cruise Control.
The Cruise Control module allows a fleet owner to set preprogrammed limits in order
to enhance overall operating economy. CC is a standard feature of the engine, and
the default CC settings are useful for a majority of applications. Before changing the
default parameters, it is strongly recommended to consult the customer and/or body
builder to review the Cruise Control options.
Standard Feature

Cruise Control

Cruise Control ON/OFF switch

Set/Accel switch

Resume/Decel switch
CC regulates engine torque to maintain the desired vehicle speed. CC ON/OFF,
Set/Accel, and Resume/Decel are in-cab switches that allow the driver to operate
CC.
The CC ON/OFF switch allows the operator to control the vehicle speed if the switch
is in the ON position. When the switch is in the OFF position, CC is deactivated and
the engine will not automatically maintain an operator-desired vehicle speed.
The Set/Accel switch allows the operator to activate CC when the CC is ON, which
assigns the current vehicle speed as the Cruise Control target speed. While CC is
active, the operator is free from having to control the vehicle speed using the
accelerator pedal. While CC is actively controlling vehicle speed, briefly pressing the
Set/Accel switch will cause the vehicle speed to increase by the value of Vehicle
Speed Increase from Set/Accel Switch Press (N005). While CC is actively controlling
vehicle speed, and the Set/Accel switch is pressed and held, the vehicle will
accelerate until the switch is released or the Maximum Cruise Control Target Speed
(N006) is reached.
While Cruise Control is ON, the Resume/Decel switch allows the operator to activate
CC and resume maintaining a previously set Cruise Control vehicle speed. The
stored target vehicle speed is reset with an ignition key cycle. While CC is actively
controlling vehicle speed, briefly pressing the Resume/Decel switch will cause the
vehicle speed to decrease by the value of Vehicle Speed Decrease from
Resume/Decel Switch Press (N004). While CC is actively controlling vehicle speed,
and the Resume/Decel switch is pressed and held, the vehicle will accelerate until
the switch is released or the Minimum Speed to Auto-Deactivate Cruise Control
(N001) is reached.

Adaptive Cruise Control (ACC)
Cruise Control Multi-Torque Mode
Adaptive Cruise Control (ACC) can overrule CC in order to maintain a set following
distance to a target vehicle. ACC is not described in this document. Refer to the
Original Equipment Manufacturer’s (OEM) documentation for a detailed description
of ACC functionality.
For engines with a multi-torque engine rating, Cruise Control Multi-Torque Mode
(N039) is an option that allows the fleet owner to specify when the extra torque
available from the multi-torque rating will be available. When this option is enabled,
the extra torque will only be available when the Cruise Control is actively controlling
vehicle speed. When the Cruise Control Multi-Torque Mode is disabled, the extra
torque will be available with or without Cruise Control.
Considerations
When programming parameters Minimum Speed to Auto-Deactivate Cruise Control
(N001), Minimum Cruise Control Enable Speed (N002), and Minimum Cruise Control
Target Speed (N003), it is important to first determine if the vehicle will be driven
while in Power Take-Off (PTO) Mode (i.e. non-stationary PTO applications). If the
vehicle will be driven in PTO Mode, Minimum Speed to Auto-Deactivate Cruise
Control (N001) must be at least 6 mph greater than Maximum Vehicle Speed During
PTO Operation (N080) (In PTO section). In addition, Minimum Cruise Control Enable
Speed (N002) must be greater than Minimum Speed to Auto-Deactivate Cruise
Control (N001), and Minimum Cruise Control Target Speed (N003) must be greater
than or equal to Minimum Cruise Control Enable Speed (N002). If the vehicle will not
be driven in PTO Mode, the default values are recommended for these parameters.

Vehicle Speed Limiter
Overview
The Vehicle Speed Limiter is designed to improve fuel economy by reducing the
maximum vehicle speed.
Standard Feature

Without Vehicle Speed Limiter
The speed of the vehicle will be limited to the maximum value of Maximum
Accelerator Pedal Vehicle Speed (N162) and Maximum Cruise Control Target Speed
(N006).
Feature Options

Vehicle Speed Limiter
Vehicle Speed Limiter
On Greenhouse Gas (GHG) compliant vehicles, Maximum Vehicle Speed Limit
(N170) will limit the overall maximum speed of the vehicle, until the GHG expiration
mileage has been exceeded. The GHG expiration mileage is available in the chassis
information within PEP, and may not be changed. For example, if Maximum
Accelerator Pedal Vehicle Speed (N162) is set to 55 mph, Maximum Cruise Control
Target Speed (N006) is set to 70 mph, and Maximum Vehicle Speed Limit (N170) is
set to 64 mph, the vehicle can be driven to a maximum speed of 55 mph with the
pedal. If Cruise Control is enabled the vehicle speed may be increased to a
maximum of 64 mph, as the vehicle will not exceed the value of Maximum Vehicle
Speed Limit (N170) when the engine is fueled.
For non-GHG compliant vehicles, or vehicles that have exceeded the GHG
expiration mileage, Maximum Vehicle Speed Limit (N170) is ignored, allowing
Maximum Accelerator Pedal Vehicle Speed (N162) and Maximum Cruise Control
Target Speed (N006) to determine the overall maximum speed of the vehicle.

Engine Protection System
Overview
The Engine Protection System monitors the engine systems for conditions that might
require the engine to either derate, or in some circumstances shut down. If any of the
monitored conditions exceed engine Protection System thresholds, the functionality
will provide a visual warning to the operator. This warning allows the operator to
adjust the operation of the vehicle to correct the condition. If the customer has
selected either derate or shutdown, and the operator has not succeeded in correcting
the condition, a derate or shutdown sequence will be initiated. Derate provides
reduced engine performance to correct the engine condition. Shutdown will turn the
engine off to prevent imminent failure.
Standard Feature

Derate
Derate allows the engine to provide a power reduction or a maximum engine speed
limitation. If an engine is equipped with derate, once a visual warning is provided and
the condition does not change, a derate will be implemented in an attempt to correct
the condition and mitigate a potential failure. Once a derate request has been
triggered, the derate will implement in 30 seconds.
Feature Options

Warning

Shutdown
Warning allows the engine to provide a visual indication that the Engine Protection
System has detected a condition that could potentially cause an engine failure.
Shutdown allows the Engine Protection System to turn off the engine if the operator
does not take action to correct the condition. When a shutdown request is triggered,
the engine will shutdown in 30 seconds. If an engine is automatically shutdown by
the Engine Protection System, the engine will be unable to start for 30 seconds.

PACCAR Engine Brake
Overview
The PACCAR Engine Brake is a fully integrated engine compression brake that
provides braking forces through the driveline. It reduces wear on the service brakes
and improves vehicle control in deceleration events when active. The PACCAR
Engine Brake operates using standard dash switches, and is customizable to meet
the requirements of the operator or fleet.
Standard Feature

PACCAR Engine Brake ON/OFF Switch

Retarder Select Switch

Manual Mode (both with cruise control turned ON and OFF)
The PACCAR Engine Brake ON/OFF switch allows the operator to turn retarder ON
and OFF.
The default setting for the PACCAR Engine Brake is Manual Mode. Manual Mode
allows the engine to provide braking when the PACCAR Engine Brake switch is in
the ON position, the engine is not being fueled, and the cruise control is inactive. The
operator may use the Retarder Select Switch to select from three levels of braking
power: Low (33%), Medium (66%), and High (100%).
When the PACCAR Engine Brake switch is in the ON position, the operator will be
notified by an indicator the driver display. Examples of the notification are provided in
the Additional Information portion of this section.
Feature Options



Downhill Speed Control (Auto-Retard in Cruise Control)

Downhill Speed Limiter (DSL)
The customer has the option to select from three operating modes for the PACCAR
Engine Brake when the PACCAR Engine Brake ON/OFF switch is ON and cruise
control is ON and inactive. The three operating modes are mutually exclusive of one
another:

PEC017
12/19/2016
Manual Mode is the default setting for the PACCAR Engine Brake when
the PACCAR Engine Brake ON/OFF switch is ON and cruise control is
ON and inactive. It behaves the same way as the Manual Mode
described in Standard Features portion of this section.
Page 34 of 90

Coast Mode allows the engine to provide braking when the PACCAR
Engine Brake ON/OFF switch is ON, the Cruise Control is ON and
inactive, and the service brake is applied. The PACCAR Engine Brake
will de-activate in Coast Mode when the service brake pedal is released
or cruise control is activated.

Latch Mode allows the engine to provide braking when the PACCAR
Engine Brake ON/OFF switch is ON, cruise control is ON and inactive,
and the service brake pedal is applied. Latch Mode will continue to
provide braking after the service brake pedal is released and will deactivate when the accelerator pedal is applied or cruise control is
activated.
Downhill Speed Control allows the engine to provide braking when the PACCAR
Engine Brake ON/OFF switch is ON, Cruise Control is active and the vehicle speed
exceeds the Cruise Control target speed plus the Downhill Speed Control Offset
Speed (N014). A large offset will reduce engine brake usage, while a lower offset will
increase engine brake usage. A lower offset is recommended for vehicles operating
in steep terrain. Downhill Speed Control will deactivate when the vehicle speed has
been reduced to the Cruise Control target speed or when Cruise Control is
deactivated. Downhill Speed Control will function independently of all other PACCAR
Engine Brake parameters.
The Downhill Speed Limiter (DSL) allows the engine to provide braking when the
PACCAR Engine Brake ON/OFF switch is ON and the vehicle speed exceeds the
Maximum Accelerator Pedal Vehicle Speed (N162) plus the Downhill Speed Limiter
Vehicle Speed Offset (N013), The Downhill Speed Limiter will function independently
of all other PACCAR Engine Brake parameters.
In Manual Mode, the Downhill Speed Limiter will activate if the vehicle speed
exceeds the Maximum Accelerator Pedal Vehicle Speed (N162) plus the Downhill
Speed Limiter Vehicle Speed Offset (N013). If the Downhill Speed Limiter is already
active, the PACCAR Engine Brake power will be increased, but if the Downhill Speed
Limiter is already at maximum capacity, the Downhill Speed Limiter will have no
effect on the PACCAR Engine Brake. The Downhill Speed Limiter will automatically
deactivate when the vehicle speed has been reduced to the Maximum Accelerator
Pedal Vehicle Speed (N162). Engine Speed Offset to Disable Engine Brake (N021)
specifies the offset above engine idle speed below which the PACCAR Engine Brake
will become disabled. Engine Speed Offset to Enable Engine Brake (N022) specifies
the offset above engine idle speed at which the PACCAR Engine Brake will become
enabled. Vehicle Speed to Enable Engine Brake (N026) determines the minimum
vehicle speed required to enable the PACCAR Engine Brake, and Vehicle Speed
Offset to Disable Engine Brake (N027) allows a vehicle speed offset from Vehicle
Speed to Enable Engine Brake (N026) below which the PACCAR Engine Brake will
become disabled.

Power Take-Off (PTO) Mode Engine Speed Control
Overview
Power Take-Off (PTO) Mode provides engine speed controls in addition to
configurable interlocks that are available to restrict PTO Mode (if required.) PTO
Mode is fully customizable with multiple programmable engine and vehicle speed
parameters and safety interlocks.
The MX engines are suitable for use in many applications requiring auxiliary PTOdriven equipment. The engine PTO controls are flexible with many customizable
features, which allow for configurations to meet the needs of many different vehicle
applications. PTO Mode can make the operation of PTO-driven equipment safer and
more convenient for the operator, and can protect both the chassis drivetrain and
PTO-driven auxiliary equipment from misuse and potential damage. The Engine Idle
Shutdown Timer (EIST) may also be disabled in PTO Mode to allow for extended
operations with the engine at idle. The engine is also capable of logging time and
fuel consumption in PTO Mode separately from non-PTO operation.
While the engine is in PTO mode, many different limitations can be imposed by
software in the engine controller. These limitations may include:

Engine Speed

Engine Speed Ramp-Up/Ramp-Down Rates

Maximum Engine Torque Output

Vehicle Speed

Engine Idle Time

Safety Interlocks
The purpose of this section is to describe the engine PTO Mode programming
features and capabilities. The default PTO settings will support many applications.
For fine-tuning of the features, it is strongly recommended that the body builder
and/or customer be consulted for their specific requirements. If no PTO is anticipated
for the vehicle or the PTO operation will not require the engine to go into PTO Mode
for specific engine speed controls or safety interlocks, no action is required at order
entry. The special features associated with PTO Mode operation may be specified
during the vehicle order process, and changes to the factory settings may be made
post-delivery via a PRS file from the PACCAR Engine Support Center.
Additional transmission configuration may be necessary depending on the equipped
transmission and/or transfer case. PACCAR recommends consulting the
transmission manufacturer for information related to specific wiring harnesses and
transmission programming requirements for proper PTO functionality. The following
references may also assist in properly configuring the transmission for PTO use:
 Allison 5th Generation Controls 1000/2000/3000/4000 Product Families –
Controls Installation Manual
 Eaton PTO Information Guide

PTO Speed Control Configuration
The standard engine programming is without PTO engine speed controls. Without
PTO Mode allows the engine to operate normally without any PTO engine speed
controls or restrictions. If the vehicle application will require the engine to go into
PTO Mode for specific throttle controls or interlocks, one of the control configurations
listed in Figure 12.1 must be selected. The following flow chart may be used to
program the required and user configurable parameters to properly configure the
vehicle to suit particular applications:

When Remote PTO Engine Speed Control is configured with one preprogrammed
preset speed, pressing Remote Set momentarily after entering PTO mode will cause
the engine speed to increase to Remote PTO Preset Engine Speed #1 (N055). This
functionality is not time dependent, and may be triggered at any time after entering
PTO Mode, provided the Remote Set switch is momentarily pressed before any other
input. If Remote Set is pressed a second time, or if any other switch is used first
upon entering PTO mode, the engine will revert to normal PTO operation and the
engine speed will no longer remain at Remote PTO Preset Engine Speed #1 (N055).
When Remote PTO Speed Control is enabled with two preprogrammed preset
speeds, momentarily pressing Remote Set will cause the engine speed to increase
to Remote PTO Preset Engine Speed #1 (N055). Pressing Remote Set again will
cause the engine speed to increase to PTO Remote Preset Speed #2 (N056).
Subsequent presses of the Remote Set switch will cause the engine speed to
increase beyond the second preset engine speed. Pressing and holding Remote Set
will cause the engine speed to steadily increase by the preprogrammed rate. The
Remote Resume switch functions normally. If it is desirable for the Remote Set
switch to always cause the engine to jump to a single predefined speed, both
Remote PTO Preset Engine Speed #1 (N055) and Remote PTO Preset Engine
Speed #2 (N056) may be programmed to the same value.
If additional preset engine speeds are required, under certain circumstances it is
possible to program the Minimum Engine Speed During PTO Operation (N106), PTO
Mode Preset Engine Speed (N087), Increase Engine Speed w/ Remote Set/Accel
Switch Bump (N092), and Maximum Switch-Controlled Engine Speed during PTO
Operation (N086) in combination to achieve more target engine speeds. For
example, four target engine speeds at uneven increments may be desired: 750, 850,
1000, and 1125 RPM. In this case, Minimum Engine Speed During PTO Operation
(N106) may be programmed to 750 RPM. PTO Mode Preset Engine Speed (N087)
may be programmed to 850 RPM. Increase Engine Speed w/ Remote Set/Accel
Switch Bump (N092) may be programmed to 150 RPM. Lastly, Maximum SwitchControlled Engine Speed during PTO Operation (N086) would be set to 1125 RPM.
With these settings, the engine would increase to 750 RPM upon entering PTO
mode. The engine would increase to 850 RPM with the first press of the Set/Accel
switch, and a subsequent press would increase the engine speed by 150RPM to
reach 1000 RPM. Another press of Set/Accel would increase the engine speed to the
Maximum Switch-Controlled Engine Speed during PTO Operation (N086), which is
1125 RPM in this scenario.
The engine speed increment and decrement values for remote or in-cab switches
may also be programmed independently to provide even greater flexibility in
achieving target engine speeds quickly. For instance the increment value may be
100 RPM while the decrement is at 50 RPM to provide an easier method for reaching
a specific engine speed. In this case, increasing the engine speed by 50 RPM can be
PEC017
12/19/2016

achieved by pressing the Set/Accel swtich, quckly followed by the Resume/Decel
switch.
When programming remote preset engine speeds, ensure that Remote PTO Preset
Engine Speed #1 (N055) is greater than or equal to Minimum Engine Speed During
PTO Operation (N106), and Remote PTO Preset Engine Speed #2 (N056) is greater
than or equal to Remote PTO Preset Engine Speed #1 (N055) and less than or equal
to Maximum Switch-Controlled Engine Speed during PTO Operation (N086).
Note: The Remote PTO Preset Engine Speed feature requires the PTO
Preprogrammed Speed Setting functionality to be properly configured as One
Speed or Two Speeds in the CECU software.
Enable In-Cab Accelerator Pedal Overrule (N307) may be enabled to allow actuating
the in-cab accelerator pedal to temporarily overrule the remote station engine speed
controls. When the cab accelerator pedal is released, the engine will revert back to
accepting speed control commands from the remote PTO station controls.
Particular applications will require the use of a split-shaft transfer case to decouple
the drive axles and fully divert engine power to auxiliary equipment. The Split Shaft
PTO Installed parameter must be enabled in the CECU using the Electronic Service
Analyst (ESA) tool. Enabling this parameter will allow the transmission to be in gear
while the parking brake is engaged without displaying the associated warnings and
audible alarms. PACCAR recommends consulting the transmission and/or transfer
case manufacturer for details on proper configuration for split-shaft PTO devices.
Note: PTO functionality for remote station controls is not currently available
for vehicles equipped with Allison and Ultrashift transmissions in applications
which require the transmission to be in-gear. Vehicles with these
configurations and requirements must rely on in-cab control configurations to
allow PTO mode functionality.
PTO Control via CAN Communication
PACCAR MX engines support remote PTO Mode controls via the B-CAN network.
Signal Source for Remote Main Switch (N102) may be configured to allow for PTO
engagement communications between the remote PTO module and the cab
electronic control unit (CECU) or via legacy hardwired connection directly from the
PTO device to the engine controller. Remote switch and remote throttle signal types
must be specified within the drivetrain parameters on the CECU. Additional
networking interface parameter changes are required within the CECU depending on
the application requirements in order to allow remote PTO control modules to
function properly via the B-CAN network. For additional information about the
required changes to the CECU parameters, consult the appropriate body builder
manual for the vehicle.
PACCAR MX engines allow for remote engine speed control functionality via TSC1
messaging from remote control modules by configuring Enable TSC1 Input from
Remote Module(N306). In addition, a hardwired or CAN PTO engagement feedback
signal must be provided to allow the engine to enter PTO mode to enable PTO
engine speed control and safety interlocks, and Signal Source for Remote Main
Switch (N102) must be configured according to the signal source of the PTO mode
request. TSC1 messages must be broadcast from source address 36 (0x24) to
destination address 0 (0x00). Messages must also specify control purpose P3: PTO
Governor to allow the engine controller to respond to TSC1 requests.
PEC017

Refer to J1939 specifications for information on specific parameter group numbers
(PGNs), including message priority, transmission rates, and suspect parameter
numbers (SPNs).
PTO Mode Interlocks
PTO interlocks provide an extra level of component protection when operating the
engine in PTO Mode. The engine enters PTO Mode when the engine receives a
signal via hardwired engagement feedback or a signal from a body controller via
BCAN. If an interlock condition exists, the engine will not enter PTO Mode until the
interlock condition is eliminated. An existing interlock condition does NOT prevent
the PTO from mechanically engaging or cause the PTO device to disengage and will
only prevent the engine from entering PTO Mode. When in PTO Mode, if one of the
interlock conditions occur, the engine control unit (ECU) reverts back to normal
driving mode and all controls, logic, and limits related to PTO Mode will become
inactive. This includes limits related to minimum engine speed, maximum engine
speed, maximum vehicle speed, and maximum engine torque. Other PTO Mode
features, such as disabling the idle shutdown timer and logging PTO Mode hours
and fuel usage will also become inactive.
The following list describes the available PTO Mode interlocks and the conditions
that will prevent the engine from entering PTO Mode, or cause the engine to exit
PTO Mode:

PTO Mode Disabled with Clutch Pedal Depressed (N078) – When this
interlock is enabled, operating the clutch pedal will cause the engine to exit
PTO Mode.
o

PTO Mode Disabled with Service Brake Depressed (N101) – When this
interlock is enabled, operating the service brake pedal will cause the engine
to exit PTO Mode.
o

Required for Mobile Cab Station Accelerator and Switches
configuration
PTO Mode Enable Only with Parking Brake Set (N079) – When this
interlock is enabled, disengaging the parking brake will cause the engine to
exit PTO Mode, or prevent the engine from entering PTO Mode.
o

Disabled for mobile applications
This interlock is automatically configured based on the selected
configuration and is required for all stationary PTO applications.
PTO Mode Enable Only with Transmission Neutral (N089) – When this
interlock is enabled, the transmission must be in neutral to allow the engine to
enter PTO Mode. With this interlock enabled, shifting the transmission out of
the neutral position will cause the engine to exit PTO Mode.
o
This interlock is disabled for mobile applications.
 Maximum Vehicle Speed During PTO Operation (N080) – While in
PTO Mode, the vehicle will not accelerate past the Maximum Vehicle Speed
During PTO Operation (N080). If the vehicle exceeds this speed limit by more
than 6 MPH, the engine will exit PTO Mode. This may happen in a downhill
PEC017
12/19/2016
Page 50 of 90
scenario or when an external force or input (such as an incline or
pushing/towing the vehicle) causes the vehicle speed to increase.
o
Maximum Vehicle Speed During PTO Operation (N080) must be at
least 6MPH less than Minimum Speed to Auto-Deactivate Cruise
Control (N001). See the section on Cruise Control for more detailed
information.
NOTE: When an interlock condition occurs, the engine will exit PTO Mode and
will disable engine speed controls and protections, but will not cause the PTO
device to mechanically disengage from the powertrain. The PTO device will
only be mechanically disengaged by toggling the PTO On/Off Switch.
When all interlock conditions are removed, and the engine is receiving a signal that
the PTO is mechanically engaged, the engine will return to PTO Mode automatically
and the engine speed will return to the Minimum Engine Speed During PTO
Operation (N106). If the Resume/Decel switch is the first switch pressed after
entering PTO mode, the engine speed will increase to the previously stored engine
speed prior to exiting PTO Mode. Otherwise, the engine speed can be increased with
the Set/Accel switch.
PTO Mode Limits and Set Points
PTO Engine Speed Control has many programmable parameters that may be
adjusted to tailor PTO Mode performance to protect specific PTO-driven equipment
from damage or misuse.
When PTO switch is in the ON position, if the PTO device is mechanically engaged
and the interlock conditions are met, the engine enters PTO Mode automatically and
the engine speed will increase to the Minimum Engine Speed During PTO Operation
(N106).
Maximum Switch-Controlled Engine Speed during PTO Operation (N086) may be
programmed to prevent the engine from exceeding a specified RPM while using the
Set/Accel or Resume/Decel switches to protect speed sensitive PTO-driven
equipment from damage due to overspeed while changing the target engine speed.
Likewise, Maximum Accelerator Engine Speed during PTO Operation (N076) defines
the maximum achievable engine speed while using the accelerator pedal. These
parameters can be programmed independently, but Maximum Accelerator Engine
Speed during PTO Operation (N076) must be greater than or equal to Maximum
Switch-Controlled Engine Speed during PTO Operation (N086).
The engine speed can be controlled by briefly pressing, or pressing and holding the
specified switches. With the PTO Mode configured for in-cab controls, these are the
cruise control Set/Accel and Resume/Decel switches. In the case of the remote PTO
control station mode, these switches are provided by the body builder and are
functionally equivalent to the in-cab Cruise Control control switches
In PTO Mode, a throttle control input is available. When PTO Mode controls are
configured in the cab, the accelerator pedal is used for throttle control in PTO Mode.
For a remote PTO Mode control station, this would be supplied by the body builder
and may be a pedal, hand lever, or similar input device.
PEC017
12/19/2016
Page 51 of 90
When in PTO Mode, pressing the Set/Accel switch momentarily will cause the engine
speed to increase by PTO Increase Engine Speed w/ Set/Accel Switch Bump
(N083). For PTO Mode configured with remote controls, Increase Engine Speed w/
Remote Set/Accel Switch Bump (N092) should be programmed instead. Each press
of the Set/Accel switch will increase engine speed by this increment, up to the
Maximum Switch-Controlled Engine Speed during PTO Operation (N086).
When in PTO Mode, pressing the Resume/Decel switch momentarily will cause the
engine speed to decrease by PTO Reduce Engine Speed w/ Resume/Decel Switch
Bump (N082). For PTO Mode configured with remote controls, Reduce Engine
Speed w/ Remote Res/Decel Switch Bump (N090) should be programmed instead.
Each press of the Resume/Decel switch will decrease engine speed by this
decrement, down to the Minimum Engine Speed During PTO Operation (N106).
When in PTO Mode, pressing and holding the Set/Accel switch will cause the engine
speed to increase at the Rate of Increase in Engine Speed w/ Set/Accel Switch Held
Down (N085), until Maximum Switch-Controlled Engine Speed during PTO Operation
(N086) has been reached. Pressing and holding the Resume/Decel switch will cause
the engine speed to decrease at the Rate of Decrease in Engine Speed w/
Resume/Decel Switch Held Down (N084), until the Minimum Engine Speed During
PTO Operation (N106) has been reached. For PTO Mode configured with remote
controls, Rate of Increase in Engine Speed w/ Remote Set/Accel Switch Held Down
(N093) and Rate of Decrease in Engine Speed w/ Remote Res/Decel Switch Held
Down (N091) should be programmed instead.
In the event the engine speed request is canceled either manually or by interlock and
the engine returns to PTO mode, the engine can be commanded to return to the
previously stored engine speed by pressing the Resume/Decel switch.
Two methods of engine speed control are available when using the Set/Accel switch,
and are selected using Enable Set Point w/ Set/Accel Switch Bump (N110):

Programmable Preset Engine Speed

Capture and Hold Current Engine Speed
When Enable Set Point w/ Set/Accel Switch Bump (N110) is OFF, pressing the
Set/Accel switch immediately after the engine enters PTO Mode will cause the
engine speed will increase to PTO Mode Preset Engine Speed (N087).
When Enable Set Point w/ Set/Accel Switch Bump (N110) is ON, the programmable
preset engine speed functionality is replaced with engine speed capture functionality.
In this configuration the Set/Accel switch may be pressed to capture and maintain
the current engine speed.
PTO Speed Maximum Rate of Change (N081) limits the maximum rate at which the
engine speed increases after a momentary operation of a PTO speed control switch.
This is intended to protect equipment that is sensitive to rapid changes in engine
speed.
Maximum Engine Torque During PTO Operation (N077) may be used to limit the
torque produced by the engine while in PTO Mode. The torque value programmed is
gross torque produced; this includes the internal calculated torque from the engine.
The torque transmitted to the driveline will be lower than the programmed value.

DPF Regeneration in PTO Mode
Regen in PTO Mode allows the engine to perform DPF regenerations while PTO
Mode is active or while the vehicle speed is less than 5 mph, allowing the engine to
run continuously without the need to exit PTO Mode to perform a stationary DPF
regeneration. This functionality is not California Air Resources Board (CARB)
compliant for MX engines manufactured prior to June 2015.
It is important to carefully evaluate the application of the vehicle prior to selecting the
Regen in PTO Mode option. There exist certain limitations on when DPF
regeneration can occur, and it may be determined that Regen in PTO Mode is not
required, or will not be beneficial to the vehicle. Refer to Table 12.7 to determine if
the application is suitable for DPF Regeneration in PTO Mode.
1) Will the vehicle be operating in PTO
Mode for durations longer than 2
hours?
2) Does the application allow the
operator to exit PTO Mode on
demand?
3) Will the customer be operating in
the upper (green) region in Figure
12.2?

Table 12.7 – Regen in PTO Mode Application Suitability
Graph 12.1 – Regen in PTO Mode Capability Map (ISO Conditions)
Graph 12.1 indicates when DPF regeneration can occur. If the engine is operated in
the green region, a DPF regen will likely be successful and Regen in PTO Mode will
be beneficial to the vehicle. If the engine is operated in the blue region, a DPF regen
is not likely to be successful and the engine should not be programmed with the

Regen in PTO mode option. For additional information or ordering assistance, please
contact the Engine Support Center.
The engine may also be configured to engage the engine fan during active DPF
regenerations while in PTO mode. Engaging the fan can provide additional engine
load and exhuast heat, which may result in more effective DPF regeneration. The
engine fan can also provided additional cooling capacity during DPF regenerations.

Driveline Protection
Overview
The Driveline Protection feature provides three different types of engine torque
curves: Driveline Protection, Standard, and Multi-Torque (MT). Driveline Protection
reduces the maximum torque curve to protect driveline components when the
drivetrain reduction is calculated to be above a specific ratio. The Standard provides
the advertised torque curves in the Ratings section of this document when Driveline
Protection and MT are not active. MT provides a maximum torque curve for use in
the top two gears of rated transmissions and is only available with the MT engine
ratings.
Standard Feature

Standard
Standard provides normal operation of the advertised torque curve.
Feature Options

Driveline Protection
Driveline Protection allows the engine to provide a maximum of 950 lbf-ft available
torque to a specified lower limit. The engine will automatically reduce the maximum
available torque when it detects a transmission gear reduction of 13.0:1 or greater.
This functionality provides the rated torque in all conditions, and only provides
protection if one or both of the following conditions are met:


The vehicle has an auxiliary transmission with gear ratio greater than 1.0:1
Vehicle has a transmission in a forward or reverse gear with a gear ratio
equal to or greater than 13.0:1
Driveline protection is automatically included within the programming for all multitorque engine ratings, but will only be enabled if/when one of the above conditions is
met. This function is required/included with the multi-torque ratings as it uses the
same software function to enable the higher torque values of the multi-torque rating.
Startability is not impacted with this function. The function only becomes active once
the vehicle is in motion and the engine is able to calculate the transmission ratio in
use.

Speed Control Management (SCM)
Overview
The Speed Control Management (SCM) feature is intended to help encourage fuelefficient shifting habits by reducing engine performance or restricting vehicle speed
at elevated engine speeds. Speed Control Management consists of two control
strategies: Progressive Shift (PGS) and Gear Down Protection (GDP), which may be
enabled separately or in combination.
PACCAR offers pre-approved and validated PGS and GDP settings for most manual
and automated-manual transmission powertrain configurations. Upon selection of at
least one of the SCM features, optimized shift points and the gears in which SCM
functionality will be active are identified by PACCAR and programmed into the
vehicle. These shift points are based on the customer’s powertrain configuration and
requested performance optimization goals.

Progressive Shift and Gear Down Protection
Progressive Shift (PGS)
The Progressive Shift module is typically used to encourage earlier shifts in lower
gears to improve fuel economy. By shifting earlier, the engine speed is reduced,
improving fuel economy. PGS is a “soft” RPM limit that restricts the rate of engine
acceleration when the engine speed is above a predefined engine speed limit. This
provides a balance between encouraging a driver to shift at lower engine speeds and
the operator’s needs to remain in a gear longer to execute a shift under heavy load
and/or on a hill. The driver’s perception of the restricted engine acceleration gives a
clear indication to execute an upshift. Full engine acceleration is restored after the
operator executes a shift where the engine speed falls below the customer-defined
limit in the next gear. Along with limiting engine acceleration, this function also
provides a visual notification to the operator to shift via the driver display.
The Progressive Shift module will provide up to two engine speed limits, allowing
customers to use a more aggressive limit in lower gears and a less aggressive limit
in higher gears. 10-speed and 13-speed transmissions will receive a two-step engine
speed limit, and 18-speed transmissions will receive a single step. The first and last
gear in which each progressive shift range is programmed ensures it is properly
configured to the customer’s application and for the specified powertrain
components.

Page 62 of 90
Gear Down Protection (GDP)
The Gear Down Protection module encourages the driver to shift into top gear when
operating the vehicle at the target operating speed. This is done by restricting the
road speed in gears below top gear. When enabled, GDP restricts operation of the
vehicle at the target operating speed when not in top gear. This effectively prevents
engine operation at excessive RPMs and, as a result, helps to improve fuel
economy. GDP is a “hard” limit. The engine RPM, and therefore vehicle speed, will
be limited to a specified value in the specified gears. Along with limiting engine RPM
and vehicle speed, this function also provides a visual notification to the operator to
shift via the driver display.
The gear down protection module offers a single programmable engine speed limit.
Selection of the GDP module will automatically set the engine speed limit at one or
two gears below top gear depending upon the combination of transmission, rear axle
ratio, and equipped tires. Changes to the factory settings can be made post-delivery
via a PRS file from the PACCAR Engine Support Center.
Application Guidelines
The SCM features are intended to be used with manual and automated-manual
transmissions while operating in manual mode. The SCM feature is not available with

Driver Reward
Overview
The Driver Reward feature is designed to improve fuel economy by providing
incentive for drivers to meet customer-defined goals for fuel economy and idle time.
The vehicle speed limit may be lowered when goals are not met, or increased to
reward drivers for meeting the goals.
Note: The Driver Reward feature is only available vehicles equipped with
PACCAR MX engines manufactured after June 2015, and is not compatible
with vehicles equipped with early model year 2015 or prior engines.

Fuel Economy
Idle Time Percentage
The Driver Reward feature provides the driver with increased vehicle speed for
meeting customer-defined fuel consumption and idle time goals. The customer has
the option of evaluating driver performance based on Fuel Economy, Idle Time
Percentage, or both. Driver Reward Offset Mode (N219) may also be configured to
apply vehicle speed rewards to the cruise control vehicle speed limit, the accelerator
pedal vehicle speed limit, or both.
The Fuel Economy option allows the engine to monitor and compare actual fuel
economy to Expected Fuel Economy (N232), which is the threshold at which neither
a reward nor penalty will be imposed on the driver. The Maximum Vehicle Speed
Bonus (N224) will be applied if the measured fuel economy is greater than or equal
to Fuel Economy Threshold for Vehicle Speed Bonus (N231). The Maximum Vehicle
Speed Penalty (N227) will be applied if the measured fuel economy is less than or
equal to Fuel Economy Threshold for Vehicle Speed Penalty (N233). As the driver
improves the measured fuel economy, the maximum vehicle speed will increase with
the driver’s performance, until the Maximum Vehicle Speed Bonus (N224) has been
reached. As the driver decreases the measured fuel economy, the vehicle speed
penalty will gradually increase with the driver’s performance, until the Maximum
Vehicle Speed Penalty (N227) has been reached.
The Percent Idle Time option allows the engine to monitor the percentage of engine
idle time and compare it to Expected Vehicle Idle Time (N236), which is the threshold
at which neither a reward nor penalty will be imposed on the driver. The Maximum
Vehicle Speed Bonus (N224) will be applied if the recorded percentage of idle time is
less than or equal to Idle Time Threshold for Vehicle Speed Bonus (N235). The
Maximum Vehicle Speed Penalty (N227) will be applied if the recorded percentage of
idle time is greater than or equal to Idle Time Threshold for Vehicle Speed Penalty
(N237). As the driver decreases the recorded percentage of idle time, the maximum
vehicle speed will increase until the Maximum Vehicle Speed Bonus (N224) has
been reached. As the driver decreases the recorded percentage of idle time, the
vehicle speed penalty will gradually increase until the Maximum Vehicle Speed
Penalty (N227) has been reached.

If Fuel Economy and Percent Idle Time are both enabled, the Driver Reward
performance criteria are evaluated individually and the overall vehicle speed bonus
or penalty will be determined from the lowest individual bonus or penalty.
The following figures may help to illustrate how the Driver Reward feature functions
under different configurations and scenarios.

Figure 17.2 - Example Driver Reward Scenario #2
PEC017
12/19/2016
Page 73 of 90
Figure 17.3 - Example Driver Reward Scenario #3
On Greenhouse Gas (GHG) compliant vehicles, Maximum Vehicle Speed Limit
(N170) will limit the overall maximum speed of the vehicle, until the GHG expiration
mileage has been exceeded. The GHG expiration mileage is available in the chassis
information within PEP, and may not be changed. For vehicles which have exceeded
the GHG expiration mileage, the Maximum Vehicle Speed Limit (N170) will be
ignored. In order to provide a speed bonus on vehicles subject to the GHG vehicle
speed limiter, the Maximum Accelerator Pedal Vehicle Speed (N162) or Maximum
Cruise Control Target Speed (N006) must be lower than Maximum Vehicle Speed
Limit (N170).
For example, a vehicle with Maximum Vehicle Speed Limit (N170) of 65MPH could
be programmed with Maximum Accelerator Pedal Vehicle Speed (N162) and
Maximum Cruise Control Target Speed (N006) at 63 MPH. Driver Reward Offset
Mode (N219) is programmed to be always on. Maximum Vehicle Speed Bonus
(N224) may be programmed to the maximum value of 4MPH. If this vehicle was
below the GHG expiration mileage, Driver Reward would only be able to reach the
vehicle speed limit of 65 MPH. If this vehicle had a GHG expiration mileage of zero
or has exceeded the GHG expiration mileage, Driver Reward would be able to reach
67MPH.
In addition, the six parameters which control the bonus, expected, and penalty
thresholds of fuel economy and idle time percentage are configurable using ONLY
the PEP interface, and the default values listed in Programmable Parameters will be
applied automatically during the ordering process. As the engine progresses in
mileage or changes duty-cycles, these parameters may be altered to more
appropriately fit the engine’s expected behavior.
