Western Star Bodybuilder Book: Revision 3.1 Engine Control Engine Brake With Cruise Control (SC 80C) Module 80C, Engine Brake With Cruise Control, has sales codes used by customers to enable engine braking when the speed of the vehicle exceeds the Cruise Control set speed. On Cummins engines, this feature has a setting for the speed increment, in MPH, above the set speed at which engine braking begins; and a setting for the speed increment, in MPH, for activating the next stage of engine braking.
Western Star Bodybuilder Book: Revision 3.1 Engine Control Dynamic Fan Braking & PTO Mode Minimum RPM (SC 80E & 80G) Module 80E, Dynamic Fan Braking, has sales codes used by customers to turn on the engine fan when the engine retarder is activated. This feature provides slightly more braking power than an engine retarder by itself. It is only possible to enable this feature when the engine has an integral retarder (module 128) and a fan drive that is controlled by the engine (module 273).
Western Star Bodybuilder Book: Revision 3.1 Engine Control Auto Elevate (SC 80L-001) The Auto-Elevate Idle feature is designed to extend the life of the aftertreatment by eliminating the hydrocarbon buildup before it reaches critical levels. To accomplish this the Auto elevate system automatically increases the engine RPM. This process results in a temporary increase of exhaust temperatures that effectively oxidizes the hydrocarbon (HC) within the Aftertreatment Device (ATD).
