A method and system for assessing or otherwise determining defective operation of an electronic control unit (ECU). The ECU may be a vehicle or non-vehicle ECU having any number of modules configured to provide and/or support any number of operations. The defective ECU operations may be determined as a function of a voltage drop across a shunt included on the ECU.
