An electromechanical system for controlling the operating mode of a selectable clutch assembly and an overrunning coupling and electromechanical control assembly are provided. The system includes a control member mounted for controlled movement and a bi-directional, electrically-powered, actuator assembly coupled to the control member for selective, small-displacement, control member movement between different positions which correspond to different modes of the clutch assembly. The actuator assembly holds the control member in a desired one of the positions after electrical power to the actuator assembly has been purposefully terminated. Control logic is operative to determine a system failure and to generate a failsafe position command signal in the event of the system failure. The actuator assembly moves the control member to a failsafe position based on the failsafe position command signal to prevent inadvertent engagement of the clutch assembly.
