A system and a method of detecting and isolating a fault in an electric motor system are provided. The method includes detecting, at a motor drive electronics (MDE) component that is configured to drive an electric motor through a harnessing, the fault in the electric motor system, applying a voltage and current, at the MDE component, according to a gate switching sequence for all phases of the electric motor system in response to detecting the fault, sensing voltage and current values in the MDE component between switches of an inverter of the MDE component, and isolating the fault within the electric motor system based on the sensed voltage and current values.
