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.

"Engine Retarder Mode" determines the operation of the auxiliary retarder output and the exhaust retarder output while the cruise control On/Off switch is in the ON position but the engine is not in cruise control. This does not determine engine retarder operation while the engine is in cruise control. Also, this does not allow engine retarder operation while the engine is in cruise control.The following modes are allowable options:
Coast
Latch
ManualWhen the "Engine Retarder Mode" is programmed to the coast mode, the engine retarder is enabled only while the service brakes are being applied. When the Engine Control Module (ECM) is programmed to the latch mode, the engine retarder stays enabled after the service brakes are released. A direct, immediate pressure on the brake pedal latches the engine retarder in the ON position and the engine retarder will remain in the ON position until the accelerator pedal is depressed.When the ECM is programmed to the manual mode, the cruise control switch is not required to be in the ON position. When the ECM is programmed to the manual mode, the engine retarder will activate when all of the following conditions are met:
The engine retarder switch is in the ON position.
The engine rpm is greater than 800 rpm.
The engine is not being fueled.

"Engine Retarder Minimum VSL Type"
The "Engine Retarder Minimum VSL Type" defines the use of the "Engine Retarder Minimum Vehicle Speed" parameter. The "Engine Retarder Minimum VSL Type" provides the following two options:
Hard limit
Soft limitIf the "Engine Retarder Minimum VSL Type" is programmed to the hard limit, the engine retarder will turn off when the value that is programmed into the engine retarder minimum vehicle speed is reached.If the "Engine Retarder Minimum VSL Type" is programmed to the soft limit, the engine retarder will remain on and the retarder will have a value that is below the value that is programmed in the engine retarder minimum vehicle speed. The engine retarder will remain on until the parameters that would normally turn off the engine retarder are met.In both cases, the engine retarder will remain off until vehicle speed is higher than the programmed value of the engine retarder minimum vehicle speed and the engine retarder has been engaged again.The following diagram illustrates the engine retarder operation for both options of the "Engine Retarder Minimum VSL Type". The engine retarder parameter is programmed to the manual option and the parameter for the engine retarder minimum vehicle speed is programmed to 48 km/h (30 mph).
Illustration 2 g00631048Note: When the vehicle speed drops below the engine retarder minimum vehicle speed and the parameter is programmed to the hard limit, the engine retarder turns off. When the vehicle speed drops below the engine retarder minimum vehicle speed and the parameter is programmed to the soft limit, the engine retarder remains on.If the engine retarder minimum vehicle speed has been programmed to 0 km/h (0 mph), the programming of the parameter for the "Engine Retarder Minimum VSL Type" does not affect the operation of the engine retarder.

"Soft Limit" "Hard Limit" "Engine Retarder Minimum Vehicle Speed"
Engine retarder minimum vehicle speed determines the minimum vehicle speed limit for the engine retarders to turn ON. Below this vehicle speed, the ECM will not turn on the engine retarder unless the vehicle is stationary. If the vehicle is stationary, the vehicle speed is 0 km/h (0 mph). If the vehicle speed signal was not being read by the ECM, the vehicle could be moving but the vehicle speed signal would be 0 km/h (0 mph). If engine retarder minimum vehicle speed is programmed to 0 km/h (0 mph) the engine retarder will operate at all vehicle speeds. This parameter affects both the engine retarder and any auxiliary retarder such as a BrakeSaver.

The "Auto Retarder in Cruise" determines the vehicle speed in kilometers per hour (km/h) or miles per hour (mph) above the cruise set speed when the engine retarder will be activated. The engine retarder switch must be in the ON position and the cruise control must be set for this feature to operate. Programming the "Auto Retarder in C
