A vehicle includes a controller programmed to, responsive to injecting a high frequency voltage signal to an electric machine, determine an estimated negative sequence current phase associated with an electric machine current, and responsive to a rotor of the electric machine being at a predetermined rotor position, inject a pulse torque command to the electric machine and observe a speed change of the electric machine to determine a cable sequence.
