3 1.0 Introduction The purpose of this guide is to help dealers assist customers in making informed decisions regarding the programming of their 2015 model year engine. 2.0 References PACCAR Engine Pro (PEP) is a North American software application used for making changes or adjusting engine parameters. 3.0 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 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, Sales Code, and Description. The Feature column identifies the feature. The Sales Code column is the division sales code used to identify a feature s setting during the ordering process. The Description column provides a short summary of the feature. Feature Sales Code Description Feature Name Sales Code # High-Level description of feature 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

4 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. Parameter Name Number Min/Max/Default/Units Parameter Name N-Code MIN = Value (Unit) Nonprogrammable Parameters MAX = Value (Unit) DEFAULT = Value (Unit) 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, 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 Parameter Name Default/Units 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. Also, 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. ON (All/Any) Setting OFF (All/Any) Setting Activate/Deactivate Requirements After a feature is ON, the function may not activate until it is triggered. A trigger is a certain event or action by an operator. Conversely, the function may not be deactivated until another event or operator action is taken. A function or feature may still be ON even when it is deactivated. To define the trigger points for activation and deactivation a reference table is given, listing the conditions required. The table is divided into two columns: Activate and Deactivate. In each column there is a list of conditions that must be met for the feature to be activated or deactivated. Also, both columns include a stipulation of All or Any in parentheses. The All indicates that every condition listed in the column is required to activate or deactivate

5 the feature. The Any indicates that only one of the conditions listed in the column is required to activate or deactivate the feature. Activate (All/Any) Condition Deactivate (All/Any) Condition Additional Information Provides supplementary data that assists in describing the feature.

6 4.0 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. Standard Feature 380 hp at 1700 rpm, 1450 lbf-ft at 1000 rpm Feature Options 405 hp at 1700 rpm, 1450 lbf-ft at 1000 rpm 405MT hp at 1700 rpm, 1550/1750 lbf-ft at 1000 rpm 430 hp at 1700 rpm, 1550 lbf-ft at 1000 rpm 430MT hp at 1700 rpm, 1550/1750 lbf-ft at 1000 rpm 455 hp at 1700 rpm, 1650 lbf-ft at 1000 rpm 455MT hp at 1700 rpm, 1550/1750 lbf-ft at 1000 rpm 485 hp at 1700 rpm, 1650 lbf-ft at 1000 rpm 500 hp at 1700 rpm, 1850 lbf-ft at 1100 rpm Orderable Feature & Options Feature Sales Code Description 380 HP Lbf 405 HP Lbf 405 HP MT Lbf Ft 430 HP Lbf 430 HP MT Lbf Ft 455 HP Lbf 455 HP MT Lbf Ft 485 HP Lbf 500 HP Lbf

9 5.0 General Settings Overview Basic engine parameters Standard Feature Maximum Vehicle Speed High Exhaust System Temperature (HEST) Warning Fuel Density Maximum Vehicle Speed (N162) defines the maximum operating governed speed of the vehicle when cruise control and Vehicle Speed Limiter is not active. High Exhaust System Temperature (HEST) Warning allows the engine to inform the operator when the exhaust temperature exceeds HEST Warning Temperature Activation Limit and the vehicle speed is less than HEST Warning Minimum Vehicle Speed (065). Fuel Density (N051) allows the customer to reprogram the engine controller with a fuel density that more accurately represents the local variation in fuel density used in their vehicles. This will, in turn, increase the accuracy of the controller s calculated fuel economy. Programmable Parameters Maximum Vehicle Speed Parameter Name Number Min/Max/Default/Units Maximum Vehicle Speed N162 MIN = 25 (MPH) HEST Warning MAX = 155 (MPH) DEFAULT = 64 (MPH) Parameter Name Number Min/Max/Default/Units HEST Warning Minimum Vehicle Speed N065 MIN = 5 (MPH) MAX = 50 (MPH) DEFAULT = 5 (MPH)

11 6.0 Idle Settings 6.1. Engine Idle Speed Overview Engine idle speed (N052) defines the minimum engine operating speed. The engine idle speed is defaulted to 650 RPM from the factory. The engine idle speed is adjustable to a maximum speed of 700 RPM. Programmable Parameters Parameter Name Number Min/Max/Default/Units Engine idle speed N052 MIN = 650 (RPM) MAX = 700 (RPM) DEFAULT = 650 (RPM) 6.2. Engine Idle Shutdown Timer (EIST) Overview The Engine Idle Shutdown Timer (EIST) is a valuable tool for fleets to restrict idle time and improve fuel economy. The EIST can be limited to a predetermined interval and may be overruled during extreme weather conditions. The EIST is programmable to respond to engine coolant temperatures which allows for longer uninterrupted warm-up time intervals. The EIST can be programmed to have more than one time interval based on whether the parking brake is set or not set. The engine load can be used to reset the EIST. While in power take-off (PTO) mode, the EIST can be turned ON or OFF with a specific time interval while in PTO Mode. The EIST is configured at the initial sale of the vehicle and some programmable parameters are locked for tamper resistance until the expiration mileage is reached. Standard Feature EIST EIST initiates when engine speed is at idle, vehicle speed is at 0 mph, and the accelerator pedal is motionless or not depressed. The interval of time until the engine shuts down is programmable; there are two programmable settings for this. One is with the parking brake ON and the other is with parking brake OFF. A warning message in the truck s driver display will indicate that shutdown is imminent, with the customer able to program when the warning should first notify the customer and countdown to shutdown of the engine. Within the standard feature there are a number of programmable features: Coolant, Oil, and Fuel Temperature Overrule Programmable resets

12 Temperature Overrules 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 was 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). Below is a list of resets that may be programmed by the customer: Accelerator Pedal Clutch Pedal Parking Brake Service Brake Engine Load Feature Options Ambient Air Temperature Overrule EIST with PTO Mode EIST Engine Load Overrule Ambient Air Temperature Overrule allows the engine to maintain operation without shutdown when the temperature is above High Ambient Air Temperature Overrule (N184) or below Low Ambient Air Temperature Overrule(N185). EIST with PTO Mode allows the EIST to shutdown the engine when PTO Mode is active. The same conditions must be met for the EIST to shutdown the engine, except programmable resets. An EIST shutdown may occur at any point in EIST with PTO Mode. EIST Engine Load Overrule allows the engine to maintain operation without shutdown when the engine load is above Engine Load Threshold (N183). Engine Load Overrule is only available when Reset EIST Timer Based On Engine Load (N190) is turned OFF. This feature is not available with EIST in PTO Mode.

20 6.3. 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. Increased engine idle speed may also be helpful for service operations such as charging the batteries or air system. 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 cannot be altered. The default FIC settings are useful for a majority of applications. In most conditions, modifications of the default settings aren t necessary. Fleet managers may find that altering some of the FIC settings may yield better fuel economy when drivers require extended idle operations. Before changing the default parameters, it is strongly recommended to consult the customer and/or body builder. Standard Feature FIC The FIC allows the operator to control the engine speed with the Set/Accel and Res/Decel switches when the Cruise Control ON/OFF switch is in the ON position, the vehicle speed is 0 MPH, the transmission is in neutral, and the parking brake is set. FIC will be overruled if the accelerator pedal request is greater than the FIC request, and the accelerator pedal will control engine speed. The FIC will deactivate if the clutch pedal or the service brake pedal are depressed. Set/Accel switch allows the operator to increase the engine speed. When FIC is active and the Set/Accel switch is bumped, the engine speed will increase by Value to Increase FIC Speed With a Resume/Decel Switch Bump (N107). When FIC is active and the Set/Accel switch is pressed and held, the engine speed will increase at Rate to Increase FIC Speed With the Set/Accel Switch Held (N103). The Res/Decel switch allows the operator to decrease the engine speed. When FIC is active and the Res/Decel switch is bumped, the engine speed will decrease by Value to Decrease FIC Speed With a Resume/Decel Switch Bump (N105). When FIC is active and the Res/Decel switch is pressed and held, the engine speed will decrease at Rate to Decrease FIC Speed With the Set/Accel Switch Held (N104). Programmable Parameters Parameter Name Number Min/Max/Default/Units Enable FIC N071 MIN = 0 (OFF) MAX = 1 (ON) DEFAULT = 1 (ON)

22 7.0 Fan Clutch Control Overview The Fan Clutch Control controls the fan clutch based on various engine temperatures. Standard Feature Fan Clutch Control Fan Clutch Control allows the engine to control the fan clutch based on coolant, charge air cooler, and power steering fluid temperatures. These temperatures are not programmable. Feature Options Minimum Fan Engagement Time Minimum Fan Engagement Time (N057) allows customization of the minimum amount of time the fan clutch is engaged before it can be turned OFF. Programmable Parameters Minimum Fan Engagement Time Parameter Name Number Min/Max/Default/Units Minimum Fan Engagement Time N057 MIN = 30 (SEC) Additional Information Fan Clutch Control on the RPM Gauge MAX = 60 (SEC) DEFAULT = 30 (SEC) Figure 7.1 shows an example of the Fan Indication on the RPM Gauge. Figure Fan Indication (Kenworth Only)

23 8.0 Cruise Control (CC) Overview The engine cruise control functionality allows the operator to set a desired vehicle speed and then adjust it within programmed limits. This allows the driver to adapt to changing vehicle speed requirements. For example, the operator can increase or decrease speed by using a switch bump. The vehicle must be within programmed limits to activate and maintain cruise control. The CC module allows a fleet owner to set preprogrammed limits in order to enhance overall operating economy. CC is a standard feature of the engine. The default CC settings are useful for a majority of applications. In most conditions, modifications of the default settings aren t necessary. Before changing the default parameters, it is strongly recommended to consult the customer and/or body builder to review CC options. Standard Feature CC CC ON/OFF switch Set/Accel switch Res/Decel switch CC regulates engine torque to maintain the desired vehicle speed. CC ON/OFF, Set/Accel, and Res/Decel are in-cab switches 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 OFF 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 sets the current vehicle speed to the operator-desired vehicle speed. The operator is free from having to control the vehicle speed using the accelerator pedal. While CC is actively controlling vehicle speed, and the Set/Accel switch is bumped, the vehicle speed will increase by the value of Value to increase CC speed with Set/Accel switch is bumped (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 CC set speed (N006) is met. The Res/Decel switch allows the operator to activate CC and resume maintaining a previously set vehicle speed, when the CC is ON. The stored operator-desired vehicle speed is reset with an ignition key cycle. When the Res/Decel is bumped, the vehicle speed will decrease by the value of Value to decrease CC speed with Res/Decel switch is bumped (N004). While CC is actively controlling vehicle speed and the Res/Decel switch is pressed and held, the vehicle will decelerate until the switch is released or the Minimum speed to automatically turn CC OFF (N001) is met.

24 Feature Options Adaptive Cruise Control(ACC) Multi-Torque with CC 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 functionality. Considerations When programming parameters N001, N002, and N003, it is important to first determine if the vehicle will be driven in PTO Mode. If the vehicle WILL NOT be driven in PTO Mode, the default values are suggested. If the vehicle WILL be driven in PTO Mode, N001, at a minimum, must be equal to N080 (In PTO section) plus 5 mph; in addition, N002 and N003 must equal N001 plus 3 mph. Example, N080 is programmed to 20 mph, then N001 will equal 26 mph at a minimum, N002 and N003 will equal 29 mph at a minimum. Programmable Parameters Parameter Name Number Min/Max/Default/Units Minimum speed to automatically turn CC OFF N001 MIN = 16 (MPH) MAX = 37 (MPH) + N080 DEFAULT = 16 (MPH) Minimum speed that CC may be enabled N002 MIN = 19 (MPH) MAX = 40 (MPH) DEFAULT = 19 (MPH) Minimum CC set speed N003 MIN = 19 (MPH) MAX = 43 (MPH) DEFAULT = 19 (MPH) Value to increase CC speed when Set/Accel switch is bumped N005 MIN = 1 (MPH) MAX = 6 (MPH) DEFAULT = 1 (MPH)

27 9.0 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 Vehicle Speed (N162) and Maximum CC set speed (N006). Feature Options Vehicle Speed Limiter Vehicle Speed Limiter Maximum vehicle speed vehicle speed limiter The Maximum vehicle speed vehicle speed limiter is the maximum vehicle speed achievable under all conditions, Maximum vehicle speed vehicle speed limiter (N170). For example if Maximum Vehicle Speed (N162) is set to 55 mph, Maximum CC set speed (N006) Is set to 70 mph, and Maximum vehicle speed vehicle speed limiter (N170) is set to 64 mph, then the vehicle can be driven to a maximum speed of 55 mph with the pedal, if cruise is enabled the vehicle speed can be increased to 64 mph as the vehicle will not exceed the value of N170 when the engine is fueled. Orderable Feature & Options Feature Sales Code Description Programmable Parameters Parameter Name Number Min/Max/Default/Units Maximum Vehicle Speed vehicle speed limiter N170 MIN = 0 (MPH) MAX = 121 (MPH) DEFAULT = 64 (MPH) Expiration Distance N169 MIN = 0 (MILES) MAX = 1,259,000 (MILES) DEFAULT = 500,000 (MILES)

29 10.0 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 implemented. 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. When a derate request is 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 a failure. Shutdown allows the Engine Protection System to turn off the engine if the operator does not 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 not start for 30 seconds.

It reduces wear on the service brakes and improves vehicle control in deceleration events when active. The PACCAR Engine Brake is customizable to meet the requirements of the operator or fleet. The PACCAR Engine Brake operates using standard dash switches. Standard Features 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 Retarder Select Switch allows the operator to set how much power is provided by the PACCAR Engine Brake. There are three levels of power provided by the Retarder Select Switch, low, medium, and high. The default setting for every 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 can select between three levels of engine retardation (low, medium, and high) through the Retarder Power Select Switch. Whenever the PACCAR Engine Brake switch is in the ON position, the operator will be notified by the driver display. Examples of the notification are provided in the Additional Information portion of this section. Feature Options Engine Brake Behavior When Cruise Control is ON: o o o Auto-Retard Manual Mode Coast Mode Latch Mode Downhill Speed Limiter (DSL) The customer has the ability 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. The default setting is Manual Mode. 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.

35 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 de-activate when the accelerator pedal is applied or cruise control is active. Auto-Retard allows the engine to provide braking when the PACCAR Engine Brake ON/OFF switch is ON, cruise control is ON and active and the vehicle speed exceeds the cruise control set speed plus the Downhill Speed Control (DSC) offset speed. Auto-Retard can be programmed independently of all other PACCAR Engine Brake parameters. Auto-Retard will de-activate when the vehicle speed just above or equal to the cruise control set speed or when cruise control is inactive. A large offset will reduce engine brake usage, while a lower offset will increase engine brake usage. A lower offset is suggested for steep terrain. The Downhill Speed Limiter allows the engine to provide braking when the PACCAR Engine Brake ON/OFF switch is ON and the vehicle speed exceeds the maximum vehicle speed plus the DSL target vehicle speed offset. 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 accelerator pedal is dead (over set vehicle speed) and the vehicle speed is over the DSL plus set vehicle speed. If while in Manual Mode the PACCAR Engine Brake is already active and the operator has an event where the vehicle speed > max vehicle speed + DSL offset speed, then the PACCAR Engine Brake power will be increased. In the case that the PACCAR Engine Brake power is already on high, the Downhill Speed Limiter will have no effect on the PACCAR Engine Brake. Downhill Speed Limiter will de-activate when the vehicle speed is reduced to the maximum vehicle speed.

40 12.0 Power Take-Off Engine Speed Control (PTO Mode) Overview The PTO Mode provides engine speed controls. In addition, configurable interlocks are available to restrict PTO Mode if required. PTO Mode is customizable with multiple settable parameters. The engine is suitable for use in many vocations which require PTO(s). The engine PTO controls are flexible with a number of customizable features. When the engine is in PTO Mode various aspects of its operation are modified by software in the engine control module (ECM). In PTO Mode, preset engine RPM range limits, engine ramp rate limits, vehicle speed limits, and engine torque limits are enabled. Also in PTO Mode idle shutdown can be disabled and the engine will log PTO hours and fuel usage. It is not necessary for the engine to be in PTO Mode for some applications (Example: dump truck). No special PTO programming is required in these cases; the default values used by the engine are adequate. For other applications, the features offered by having the engine in PTO Mode can make the operation of PTO-driven equipment more convenient, and can protect both the chassis drivetrain and PTO-driven equipment from misuse. The special features associated with PTO Mode operation may be specified during the vehicle order process. Alternatively, all these Engine Control Unit (ECU) parameters are available for modification in the aftermarket by way of new engine software, a Parts RAPIDO Subset (PRS) file. The purpose of this section is to introduce 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, no action is required at order entry. PTO Control Configurations If no PTO is anticipated for the vehicle or the PTO operation will not require the engine to go into PTO Mode for specific throttle controls or interlocks, then no action is required at order entry. The standard engine setting is without PTO engine speed controls. Without PTO Mode allows the engine to operate normally without any PTO engine speed controls. If PTO Mode will be used and the operation is such that it will require the engine to go into PTO Mode for specific throttle controls or interlocks, one of the four basic control configurations listed in the table below must be selected.

41 Pedal PTO Switch Throttle Cab Cab Set & Resume Switch Remote Throttle Control Remote Set & Resume Switch Cab Controls with Accelerator Pedal Cab Controls without Accelerator Pedal Remote Station with Remote Throttle Remote Station without Remote Throttle On Enabled Enabled Disabled Disabled On Disabled Enabled Disabled Disabled On Disabled Disabled Enabled Enabled On Disabled Disabled Disabled Enabled For applications where PTO Mode controls are located inside the cab and the accelerator pedal is to remain active, use Cab Controls with Accelerator Pedal (Example: Dump Truck). For applications where cab controls will be used to control the engine speed in PTO Mode and the accelerator is required to be disabled, use Cab Controls without Accelerator Pedal (Example: Tanker). For applications with a remote PTO Mode control station using switches while also requiring full range throttle control, use Remote Station with Remote Throttle (Example: Mobile Crane). It is recommended that when remote throttle controls will be used, remote PTO and throttle provisions be added. For applications with a remote PTO Mode control station using only switches to control engine speed in PTO Mode, use Remote Station without Remote Throttle (Example: Vacuum Truck). It is recommended that when remote controls will be used, remote PTO provisions be added. Feature Options 1 Programmable Preset Engine Speeds in Remote PTO Mode 2 Programmable Preset Engine Speeds in Remote PTO Mode 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 PTO Remote Preset Speed #1 (N055). This functionality is not time dependent, and PTO Remote Preset Speed #1 (N055) can be triggered at any time after entering PTO mode as long as Remote Set is momentarily pressed before any other switch. After pressing Remote Set, or if any

42 other switch is used first after entering PTO mode, the engine will revert to normal PTO operation. When Remote PTO Speed Control is enabled with two preprogrammed preset speeds, momentarily pressing Remote Set will cause the engine speed to increase to PTO Remote Preset 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 jump to the last used preset 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 predefined speed, both PTO Remote Preset Speed #1 (N055) and PTO Remote Preset Speed #2 (N056) can be programmed to the same value.

43 PTO Mode Interlock Configurations PTO interlocks provide an extra level of component protection. The engine enters PTO Mode when the engine receives a signal that the PTO is mechanically engaged unless an interlock condition exists. 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. When in PTO Mode, if one of the interlock conditions occur, the engine control unit (ECU) reverts back to normal driving mode and limits associated with normal driving mode (such as governed maximum engine speed) become active. That means all the controls, logic, and limits related to PTO Mode instantly turn off. That 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 turn off. At that point the engine speed is controlled by the cab accelerator pedal (or goes to idle if there is no accelerator pedal input). When the interlock condition is removed (assuming the engine is still receiving a signal that the PTO is mechanically engaged), the engine returns to PTO Mode automatically and the engine speed goes to the minimum engine speed during PTO operation (N106). If the Resume/Decel button is the first button pressed after entering PTO mode, the engine speed will increase to the last stored engine speed prior to exiting PTO Mode. Otherwise the engine speed can be increased with the Set/Accel button. NOTE: When an interlock condition occurs, it takes the engine out of PTO Mode, but it does not mechanically disengage the PTO from the powertrain. This section describes the available PTO Mode interlocks and the conditions that will cause PTO Mode to not enable or cause the engine to drop out of PTO Mode. The following interlocks are available: Clutch Interlock (N078) Operating (depressing/actuating) the clutch pedal will disengage PTO Mode. Service Brake Interlock (N101) Operating (depressing/actuating) the service brake pedal will disengage PTO Mode. This interlock is required for mobile applications and/or UltraShift transmissions. Parking Brake Interlock (N079) The parking brake must be engaged for PTO Mode to be enabled. Neutral Interlock (N089) The transmission must be in neutral for PTO Mode to be enabled. This interlock feature is not available with UltraShift Transmissions. Maximum Vehicle Speed Interlock (N080) The vehicle must not exceed a preset speed or PTO Mode will not be enabled. While in PTO Mode, the vehicle will not accelerate past the set PTO ON Interlock Vehicle Speed Limit (N080). If the vehicle exceeds this set speed limit by more than 6 MPH it will disengage PTO Mode. This would only happen in a downhill scenario or similar situation where an external force or input causes the vehicle speed to increase. Remote Station Controls With Transmission Driven PTO (N088) This allows the use of remote station controls with a transmission driven PTO (such as a

44 split shaft PTO) where the transmission is required to be engaged but the drive wheels are disengaged. To enable this feature the Parking Brake Interlock must be ON (N079 = 1), the Maximum Vehicle Speed must be set to 1 (N080 = 1) and the Neutral Interlock must be off (N089 = 0).

45 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. This allows the engine to run continuously without the need to perform a stationary DPF regeneration. In order to enable PTO regeneration, the chassis must be coded for a 3 way regeneration switch and must not have a horizontal tailpipe. It is important to carefully evaluate the application of the vehicle prior to selecting the PTO Regen 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. The following table will help 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? No DPF Regeneration in PTO Mode is not recommended Yes Continue to #2 2) Does the application allow the operator to exit PTO Mode on demand? No Continue to #3 Yes DPF Regeneration in PTO Mode is not recommended 3) Will the customer be operating in the upper (green) region in Figure 12.1? No Yes DPF Regeneration in PTO Mode is not recommended DPF Regeneration in PTO Mode is recommended for this application Figure 12.1 Regen in PTO Mode Capability Map (ISO Conditions) Figure 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 a benefit to the vehicle. If the engine is operated in the blue region, a DPF regen

46 is not likely to be successful and the engine should not be programmed with Regen in PTO mode. For additional information or ordering assistance, please contact the Engine Support Center. Fan Assist The fan assist feature enables the engine fan during DPF regeneration. The extra load on the engine from the fan creates more heat in the exhaust system and allows the regeneration system to work within a larger operating range. This feature can help in colder climates, when the PTO has lower torque loads, or low RPMs. Orderable Feature & Options Feature Sales Code Regen in PTO Mode Description ENABLE ENGINE REGENERATION IN PTO MODE Cab Accelerator Pedal Type in PTO Mode The Cab Accelerator Pedal Type in PTO Mode (N073) allows the driver to choose between two accelerator pedal operations in PTO Mode. Torque Pedal (Default): Pedal position determines the engine torque (automotive style control). This is the standard accelerator pedal setting during normal driving conditions out of PTO mode. This setting will keep a common accelerator feel both in and out of PTO mode. Linear Speed Pedal: Pedal position determines engine speed. This setting allows finite engine speed control based off of accelerator pedal position. This setting works well when constant engine speed is required under varying torque conditions. Note: The remote throttle uses linear speed control similar to the Linear Speed Pedal option above. PTO Mode - Limits and Set Points The following parameters may be programmed to configure PTO Mode performance. In PTO Mode the maximum engine speed can be defined. Setting this parameter appropriately will protect speed sensitive PTO-driven equipment from damage due to overspeed while changing the engine speed set point. Minimum engine speed can also be defined in PTO Mode. When PTO switch is turned on and the interlock conditions are met, the engine enters PTO Mode automatically and the engine speed goes to the minimum engine speed during PTO operation (N106). In all PTO Mode configurations, momentary action control switches are available to control engine speed. With the PTO Mode control station in the cab these would be the cruise control Set/Accel and Resume/Decel buttons. In the case of the remote PTO control station mode, these switches would be provided by the body builder. The remote switch is functionally equivalent to the dash cruise control switches.

47 After PTO Mode is deactivated and re-activated, depressing the RESUME/DECEL button will return the engine to the previous engine speed. This value is reset after a key cycle. In PTO Mode, a throttle control input is available. For a PTO Mode control station in the cab, this would be the accelerator pedal. For a remote PTO Mode control station, this would be supplied by the body builder and may be a pedal, hand lever, etc. When in PTO Mode, pressing the Set/Accel button momentarily will cause the engine speed to increase. The amount of this increase is programmable. Each press of the Set/Accel button will increase engine speed by this amount, up to the maximum engine speed limit in PTO control mode. When in PTO Mode, pressing the Resume/Decel button momentarily will cause the engine speed to decrease. The amount of this decrease is programmable. Each press of the Resume/Decel button will decrease engine speed by this amount, down to the minimum engine speed limit in PTO control mode. When in PTO Mode, pressing and holding the Set/Accel button will cause the engine speed to increase. The rate of this increase is programmable. As long as the Set/Accel button is held down, engine speed increases at the programmed rate, up to the maximum engine speed limit for PTO control mode. Similarly, pressing and holding the Resume/Decel button will cause the engine speed to decrease at a programmed rate, down to the minimum engine speed limit for PTO Mode. The engine can be programmed to go to a predetermined engine PTO Mode operating speed with in-cab or remote controls configured. After the PTO is mechanically engaged and after the first momentary operation of the SET/ACCEL or Remote Set switch, the engine will increase in RPM to a predefined speed. The maximum rate at which the engine speed increases after a momentary operation of a PTO control switch is programmable. This protects equipment that is sensitive to rapid changes in engine speed. The engine can be programmed to limit the torque produced to a specific value while in PTO Mode. When Maximum Torque Limit in PTO is programmed to a specific value the engine will limit its torque production to the programmed amount. The torque value programmed is gross torque produced; this includes the internal torque from the engine. The torque transmitted to the driveline is less than the programmed value.

53 13.0 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 MT Driveline Protection allows the engine to provide 950 lbf-ft maximum available torque to specified lower limit. The engine will automatically reduce the maximum available torque when it detects a transmission gear reduction of 15.0:1 or greater. This functionality protects the driveline only in condition 1 or 2 below; otherwise it provides the rated torque in all other conditions. 1. Vehicle has an auxiliary transmission with gear ratio greater than 1.0:1 2. Vehicle has a transmission in a forward or reverse gear with a gear ratio equal to or greater than 15.0:1 Driveline protection is automatically included within the programming for all multi-torque 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 enabled after vehicle speed is greater than zero and the engine is able to calculate the transmission ratio in use.

55 14.0 Speed Control Management (SCM) Overview The engine can include tools to help fleets encourage fuel efficient operation of the vehicle. These tools make up the SCM feature. The SCM feature consists of two control strategies: Progressive Shift (PGS) and Gear Down Protection (GDP). PGS and GDP can be enabled separately or in combination. PACCAR offers pre-approved and validated PGS and GDP settings for most manual transmission powertrain configurations. Upon selection of at least one of the SCM features, optimized shift points and the gears in which shift points are 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. Standard Feature Without SCM Feature Options PGS GDP PGS and GDP 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 driver avoids operating the engine at high RPMs, thus 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 shift to the next higher gear. Full engine acceleration capability 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.

56 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 tire family. Changes to the factory settings can be made postdelivery via a PRS file from the PACCAR Engines Support Center.

59 15.0 Engine Recorder Overview The Engine Recorder records three types of engine-sensor and calculated-output data over the life of the vehicle, between reset and defined durations. Each type of data record is stored independently and depending on the type, multiple records might be stored. The records for the three recorders are retrievable with the DAVIE service tool. Standard Feature Chart Recorder Trip Recorder Snapshot Recorder Faststop Recorder The Chart Recorder allows the engine to store data over the life of the vehicle. The Trip Recorder allows the engine to store data between resets. When the trip reset is triggered, the record is discarded and new data is collected. The Snapshot Recorder allows the operator to trigger a recording event. Details on triggering the Snapshot Recorder are available in Engine RAPIDO. The Snapshot Recorder will record data 10 seconds before and 5 seconds after the trigger. Three Snapshot Recorder events will be stored. Faststop Recorder allows the engine to trigger a recording event when vehicle deceleration is greater than Deceleration Rate to Trigger Faststop Recorder (N064).

61 16.0 Driver Shift Aid Overview The Driver Shift Aid feature helps to reduce engine fuel consumption by communicating to the driver the need to upshift in order to reduce engine speed. It is designed to notify the driver when an upshift should be performed. Depending on conditions, the driver display may recommend an upshift of one or two gears. Driver Shift Aid is compatible with vehicles equipped with manual transmissions or automated manual transmissions (AMTs). For AMTs, Driver Shift Aid is only available when the transmission is in manual mode. The Driver Shift Aid feature is only available on vehicles equipped with late model year 2015 engines, and is not compatible with vehicles equipped with early model year 2015 or prior engines. Standard Feature Without Driver Shift Aid Feature Options Driver Shift Aid The Driver Shift Aid displays a visual notification encouraging the driver to upshift in order to reduce engine speed and decrease engine fuel consumption. Driver Shift Aid is calibrated to only display the upshift icons when the recommended upshift would not adversely affect the vehicle s drivability. Driver Shift Aid is configurable to meet the customer s specific application needs. Minimum Driver Shift Aid Speed (N246) defines the speed at which Driver Shift Aid becomes active. Below this speed, Driver Shift Aid will not display upshift notifications. Lowest Driver Shift Aid Gear ratio (N247) defines the lowest selected gear that Driver Shift Aid will become active, while Highest Driver Shift Aid Gear ratio (N248) defines the highest selected gear that Driver Shift Aid functionality will remain active.

64 17.0 Driver Reward Overview The Driver Reward feature is designed to provide incentive for drivers that maximize fuel economy. Driver Rewards are based upon several different performance metrics that relate to both fuel mileage and idle time. Each metric generates a bonus or penalty speed based on current performance versus expected value. Bonus/Penalty speed is controlled by the lowest performing metric. Standard Feature Without Driver Reward Feature Options Driver Reward Enabled The Driver Reward feature provides the driver with increased vehicle speed for meeting pre-defined goals related to fuel consumption and idle time. Three parameters are available for customization in both PACCAR Engine Pro (PEP) and Prospector. Driver Reward Speed Bonus (N224) and Penalty (N227) can be tailored to meet customer-specific needs. The engine can also be configured to apply driver reward offsets only in certain operating conditions using Offset Mode (N219). Offset Mode may be configured to apply vehicle speed offsets to cruise control only, pedal only, or both. The standard configuration will not allow for bonus speed on the truck with the VSL (N170) set to the same value as the Max Pedal (N162) or Max Cruise (N006) speed. In order to provide bonus either the Max Pedal/Cruise speed must be lowered or the VSL must be raised. In addition Driver Reward also features six parameters which are configurable using ONLY the PEP interface. These six parameters control the thresholds for bonus, expected, and penalty behavior of fuel economy and % idle time. As the trucks progress in mileage or change in route, these parameters can be changed to more appropriately fit the expected behavior of the truck.
