Claim 6:
7. The method of claim 6, wherein detecting the position failure of the transfer conduit includes:
measuring, by the controller, a rate of change in current applied to the washer pump motor in a state in which the discharge hole of the transfer conduit is controlled to be located at a position corresponding to the nozzle unit;
determining whether the measured rate of change in current exceeds a rate of change in current predetermined in the controller;
when the measured rate of change in current exceeds the predetermined rate of change in current, re-determining whether the rate of change in current of the washer pump motor exceeds the predetermined rate of change in current in the same nozzle unit; and
when the rate of change in current is determined as exceeding the predetermined rate of change in current in the same nozzle unit, determining the transfer conduit as being in the position failure.
