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. If the engine brake does
not have multiple stages (e.g., exhaust flap), no difference in engine braking will be noted. On Detroit Diesel and Mercedes
engines, there are 6 settings: a minimum speed above the Cruise Control set speed and a maximum speed above the Cruise
Control set speed for the low, medium, and high engine braking stages. If the engine brake does not have multiple stages (e.g.,
exhaust flap), no difference in engine braking will be noted, however, the 6 settings must still be set correctly to ensure
uninterrupted operation of the engine brake.
