"Low Cruise Control Speed Set Limit"
The "Low Cruise Control Speed Set Limit" sets the lowest vehicle speed that will allow the cruise control to be set. Programming this parameter to the maximum value disables cruise control.
Table 1
Minimum     Maximum     Default    
24 km/h (15 mph)    
204 km/h (127 mph)    
204 km/h (127 mph)    "High Cruise Control Speed Set Limit"
The "High Cruise Control Speed Set Limit" sets the highest vehicle speed that will allow the cruise control to be set. If a driver attempts to set a vehicle speed higher than this limit, the "High Cruise Control Speed Set Limit" will be the cruise set speed. If the "High Cruise Control Speed Set Limit" is programmed to a value that is greater than the "Vehicle Speed Limit", the cruise control switches can be used to exceed the programmed "Vehicle Speed Limit".

"Exhaust Brake Mode" determines the operation of the engine brake while the cruise control on/off switch is in the ON position but the engine is not in cruise control. This does not determine the operation of the engine brake while the engine is in cruise control. Also, this does not allow operation of the engine brake while the engine is in cruise control.The following modes are allowable options:
Coast
Latch
ManualWhen the "Exhaust Brake Mode" is programmed to "Coast", the engine brake is enabled only while the service brakes are being applied. When the ECM is programmed to "Latch", the engine brake stays enabled after the service brakes are released. A direct, immediate pressure on the brake pedal latches the engine brake in the ON position and the engine brake will remain in the ON position until the accelerator pedal is depressed.When the "Exhaust Brake Mode" is programmed to "Manual", the engine brake operates independently of the cruise control status.The engine brake operates with the application and the release of the service brake in the coast mode.The engine brake turns on with the application of the service brakes in the latch mode. The engine brake stays on even when the service brakes are released.

"Cruise/Idle/PTO Switch Configuration" defines the function of the set/resume switch for "ACCEL" mode and "DECEL" mode. This parameter affects cruise control mode, idle mode and PTO mode.

"Set/Decel-Res/Accel"     "Set/Accel-Res/Decel"    "Soft Cruise Control"
"Soft Cruise Control" provides a 8 km/h (5 mph) operating range around the cruise control set speed in order to provide a smoother cruise control. "Soft Cruise Control" controls the cruise speed within the following range:
4 km/h (2.5 mph) below the set vehicle speed at full load
4 km/h (2.5 mph) above the set vehicle speed at no load
