Abstract
A system having unified diagnostics where an electrical energy storage device may supply an actuator. Various techniques may be used to determine energy storage capacity and actuator current usage. Measured storage capacity and actuator current may indicate the health of the energy storage device and the actuator, respectively. Also, operation of a service switch for the actuator may be checked relative to its state.
