1. A method for operation of a differential system, comprising:
at a circuit board assembly that is directly coupled to a coil assembly in an electromagnetic solenoid actuator, selectively locking and unlocking speed differentiation between a pair of axle shafts based on signals from a sensor included in the circuit board assembly; and
periodically placing control circuitry in the circuit board assembly in a lower power consuming state for a duration which is less than a duration of locking or unlocking speed differentiation.
