<p>The present invention relates to a method for diagnosing disconnection in a brushless motor connection line, including the steps of: temporarily reserving an operation of a brushless direct current motor when a vehicle is started; supplying an input current of a smaller size than an operation range of the brushless direct current motor to an electric wire to connect a transmission control unit and the brushless direct current motor; measuring a size of an output current which is feedbacked from the electric wire; determining whether the measured size of the output current is smaller than a size of a predetermined range; and determining that there is disconnection in the electric wire if the size of the output current is smaller than the size of the predetermined range.</p> |
