Alternative Default
"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.

0 km/h (0 mph) 204 km/h (127 mph) 0 km/h (0 mph) "Auto Retarder in Cruise"
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 Cruise" parameter to zero disables this feature. This parameter affects the engine while the cruise control is activated.Note: This parameter only affects the factory installed engine retarder (compression brake). This parameter does not affect an auxiliary braking device or Brakesaver.The actual level of braking is limited by the settings of the retarder switch. For example, the retarder will not come on if
