ABSTRACT:
A system for modifying or disabling a selected engine function in response to a determination based upon a precipitation sensor input that precipitation is present. The system also may include an ambient temperature sensor that determines whether the ambient temperature is below a predetermined level. Signals from the precipitation sensor and temperature sensor are provided to an engine controller. The engine controller functions to modify or disable a selected engine function such as a compression brake, engine exhaust brake, maximum speed calibration or passing speed variance calibration.
