ABSTRACT:
A power window device for lowering and raising window glasses. A window switch is operated to move a corresponding window glass. A motor drives the window glass when the window switch is operated. An ECU is provided for each window glass to control the motor in accordance with the operation of the window switch. An engine switch shifts positions to drive an engine. A control signal generator generates a signal to validate or invalidate control of the ECU over the motor. A control circuit determines that a signal wire connecting the ECUs to the control signal generator is in an unexpected condition when a signal cannot be received. The control circuit overrides the signals generated by the control signal generator when the signal wire is in an unexpected condition.
