Abstract
A control system for an automotive vehicle multi-functional apparatus employs an electronic control unit (251) operably controlling a rear window wiper assembly. In another aspect of the present invention, an electronic control unit is operable as a multiplexed rear node (251) for controlling a variety of liftgate devices and functions. In a further aspect of the present invention, an electronic control unit (251) controls a single multi-functional electromagnetic device. The multi-functional electromagnetic device uses intermittent motion mechanisms to selectively operate differing devices driven therefrom. A method of operating the electronic control unit (251) of the present invention is also provided.
