A system for a vehicle includes a battery of the vehicle, a plurality of switches connected to the battery, and a plurality of subsystems of the vehicle connected to the battery via the switches and wires. The system includes a controller configured to control the switches and the subsystems, and to identify a variation in a rate of change of current characteristic in frequency domain for a current loop including one of the switches, one of the subsystems, and a plurality of the wires. The controller is configured to determine integrity of the plurality of the wires and connections of the wires in the current loop based on the variation in the rate of change of current characteristic for the current loop.
