Remote Up / Down Function does not Operate: Description

When the ignition switch is ON and the window lock switch is set to UNLOCK, the power window regulator master switch sends remote signals to the multiplex network door ECU front LH (driver door ECU), and the remote signals are then passed to the multiplex network door ECU front RH (passenger door ECU). The multiplex network door ECU front RH then activates the appropriate power window regulator motor.
