Road Speed Limiting (RSL)
Road Speed Limiting (RSL) is a feature designed to regulate the maximum vehicle speed as controlled by the accelerator pedal.
Customer programmable parameters within the ECM provide vehicle speed governor related options that can be adjusted to suit the customer’s needs. A parameter is used to set the maximum accelerator controlled vehicle speed.
Additional programming flexibility is included to allow a trade-off to be made between performance and fuel economy.
Cruise Control
The ECM controls the cruise control feature. The cruise control system functions similarly for all electronic engines. Maximum and minimum allowable cruise control speeds will vary based on model. To operate cruise control, see appropriate truck model Operator’s Manual.
Traction Control
Traction control is a system that identifies when a wheel is going faster than the other wheels during acceleration.
When a traction control condition occurs, a datalink message is sent to the ECM to limit fuel for the purpose of reducing engine torque.
Vehicles must have a transmission and an Antilock Braking System (ABS) that supports traction control.
Exhaust Brake
The exhaust brake increases exhaust back-pressure to aid in the deceleration rate of the vehicle. This option is placed in the exhaust piping after the turbochargers. This option cannot be combined with the engine brake.
under the engine valve cover. This option cannot be combined with the exhaust brake.
Engine Warning Protection System (EWPS) The EWPS safeguards the engine from undesirable operating conditions to prevent engine damage and to prolong engine life. The ECM will illuminate the red ENGINE lamp and sound the warning buzzer when the ECM detects:
• High coolant temperature
• Low oil pressure
• Low coolant level (3-way system only)
When the protection feature is enabled and a critical engine condition occurs, the on-board electronics will shut the engine down (3-way protection). An event logging feature will record the event in engine hours and odometer readings. After the engine has shutdown, and the critical condition remains, the engine can be started for a 30-second run time.
For complete EWPS description and additional information, see EWPS (page 329) in
the “ELECTRONIC CONTROL SYSTEM
DIAGNOSTICS” section of this manual.
Idle Shutdown Timer (IST)
GOVERNMENT REGULATION: State and local regulations may limit engine idle time. The vehicle owner or operator is responsible for compliance with those regulations.
The IST allows the Engine Control Module (ECM) to shut down the engine during extended engine idle times.
Thirty seconds before IST-defined engine shutdown, a vehicle instrument panel indicator activates. There
This continues until the engine shuts down or the low idle shutdown timer is reset
IST for California ESS Compliant Engines
Beginning in 2008 MY, all International® MaxxForce®
engines certified for sale in the state of California will conform to mandatory California Air Resources Board (CARB) Engine Shutdown System (ESS) regulations.
Engine idle duration is limited for California Engine Shutdown System (ESS) compliant engines as follows:
• When vehicle parking brake is set, the idle shutdown time is limited to the California Air Resources Board (CARB) requirement of five minutes
• When vehicle parking brake is released, the idle shutdown time is limited to the CARB requirement of 15 minutes
The duration of CARB mandated values can be reduced by programming the customer IST programmable parameter to a value lower than 15 minutes.
Engine Idle Shutdown Timer (IST for Federal–Optional)
Idle time can be programmed from 5 to 120 minutes.
While the EST is installed, the IST function will be active with the programmed shutdown time in effect.
Parking brake transitions reset the idle timer. If the IST is enabled, the Cold Ambient Protection (CAP) will not function.
For additional information, see IST System (page 387) in “ELECTRONIC CONTROL SYSTEM DIAGNOSTICS” section of this manual.
Electronic Fan (EFAN)
Engine electronics allow for the operation of an electronic fan or an air fan solenoid. The electronic fan commands higher airflow through the radiator when the Air Conditioner (A/C) is on or when the coolant or inlet air temperature goes above a set temperature. For additional information, see EFC (page 300) in “ELECTRONIC CONTROL SYSTEM DIAGNOSTICS” section of this manual.
Radiator Shutter Enable (RSE)
The Radiator Shutter Enable (RSE) feature provides a signal to open or close the radiator shutters. Closing the shutters will keep the engine warm during cold weather operation. This provides faster warm up of the passenger cab and enables faster windshield defrosting.
In Cab Power Take Off (PTO) Control
The engine speed control feature, commonly referred to as Power Take-off (PTO), provides a method for an operator to set and maintain a constant engine speed without using the accelerator pedal. It is commonly used for powering auxiliary devices.
Customer programmable parameters within the ECM provide in-cab engine speed control related options that can be adjusted to suit the customer’s needs.
Choosing whether the operator is allowed to increase the engine speed using the accelerator pedal without disengaging the PTO is an example.
Remote Accelerator Pedal Position (RAPP) This engine speed control feature, commonly referred to as PTO, provides a method for an operator to set and maintain engine speed without using the accelerator pedal. It is commonly used for powering auxiliary devices.
When control over engine speed is required from outside the vehicle’s cab, remote mounted switches must be used to turn on PTO engine speed control and select the desired engine speed. This functionality is referred to as remote engine speed control (RESC).
The engine speed can be ramped up and down with RESC similar to the way the in-cab PTO feature works, however, the RESC feature includes two additional switches (remote preset and remote variable), which allow the operator to choose the mode of engine speed control operation.
Customer programmable parameters within the ECM provide RESC related options that can be adjusted to suit the customer’s needs. Choosing whether a remote throttle pedal is used for PTO operation is an example.
Change Engine Oil Interval Message
The service interval feature is designed to provide a visual reminder to the operator that the oil change interval has expired and that routine maintenance procedures should be performed.
The term “interval” in this case is used to describe the distance, time, or fuel used between the last maintenance performed on the vehicle and the next maintenance, which is due.
It is essential that operators are trained to know the maintenance schedules and instructions regarding the operation and reset functionality of the service interval for the feature to be effective.
The change engine oil interval message can be programmed with the EST for mileage, hours, or amount of fuel used. The change oil message timer can be reset using the CRUISE ON and RESUME/ACCEL switches or the EST.
Fuel Heater
The fuel heater is installed in the fuel filter assembly.
The heater warms the supply fuel to prevent waxing during cold conditions.
