A device for measuring currents induced in a CAN bus harness. In some embodiments, the device includes a first termination node, a second termination node, a current separator, a detection circuit, and a power source circuit. The current separator circuit has an RF transformer connected to the first termination node and separates a common mode RF current and a differential mode RF current of an RF current signal. The detection circuit is connected to the current separator circuit and receives at least one of the common mode RF current and the differential mode RF current from the separator circuit. The detection circuit also converts the common mode RF current and differential mode RF current to an non-RF output signal. The power source circuit provides power to the detection circuit.
