Apparatus and methods are provided for diagnosing faults in multiple, associated motor-resolver systems. One apparatus includes a swapping circuit coupling a first resolver to a first or second decoder, and a swapping circuit coupling a second resolver to the first or second decoder. One method includes applying a signal from a resolver to a first decoder to determine that the first decoder is malfunctioning if the first decoder continues to generate a fault signal, and applying a signal from a different resolver to a second decoder to determine that a motor associated with the first decoder is malfunctioning if the second decoder generates a fault signal. Another method includes transmitting a signal from a resolver to first and second decoders, transmitting a signal from a different resolver to the first and second decoders, and determining if the first decoder, second decoder, a first motor, or a second motor is malfunctioning.
