A diagnostic system for a hybrid vehicle comprises a motor control module and a fault diagnostic module. The motor control module controls torque output of an electric motor having a predetermined number of phases. The fault diagnostic module determines a position of a rotor of the electric motor, aligns the rotor with a phase angle of one of the phases, selectively diagnoses a fault based on a current of at least one of the phases, and selectively disables the electric motor based on the diagnosis.

What is claimed is: 1. A diagnostic system for a hybrid vehicle, comprising:a motor control module that controls torque output of an electric motor having a predetermined number of phases; anda fault diagnostic module that determines a position of a rotor of said electric motor, that aligns said rotor with a phase angle of one of said phases, that selectively diagnoses a fault based on a normalized current of at least one of said phases, that determines said normalized current based on a first current of said one of said phases measured when said rotor is aligned with said phase angle and a second current of said one of said phases measured over a period after said rotor is aligned with said phase angle, and that selectively disables said electric motor based on said diagnosis.
