POWER WINDOW CONTROL SYSTEM SYSTEM DESCRIPTION



  1. POWER WINDOW CONTROL SYSTEM DESCRIPTION


    1. The power window control system controls the power window operation using the power window regulator motors. The main controls of this system are the power window regulator master switch assembly (mounted on the driver door), power window regulator switch assembly (mounted on the front passenger door) and rear power window regulator switch assemblies (mounted on the rear doors). Operating a window switch results in electrical power being transmitted to the corresponding power window regulator motor.

  2. FUNCTION OF MAIN COMPONENTS

    The power window control system consists of the following components:

    Component Outline
    Power window regulator master switch assembly

    • Located on the driver door.

    • Controls power window operation for all windows.

    • When the window lock switch is set to the lock position, window operation will be possible for all windows.
    Power window regulator switch assembly

    • Located on the front passenger door.

    • Controls front passenger window operation.

    • Rear power window regulator switch assembly LH

    • Rear power window regulator switch assembly RH

    • Located on the rear doors.

    • Each switch controls window operation for its respective window.

    • Front power window regulator motor assembly RH (for RHD)

    • Front power window regulator motor assembly LH (for LHD)

    • Receives switch signals and changes signals into motor activation. As a result, the window position changes.

    • Uses the Hall-ICs built into the regulator motor and the power window ECUs to detect the window position, jamming and catching.

    • Front power window regulator motor assembly LH (for RHD)

    • Front power window regulator motor assembly RH (for LHD)

    • Rear power window regulator motor assembly LH

    • Rear power window regulator motor assembly RH

    • Receives switch signals and changes signals into motor activation. As a result, the window position changes.

    • Uses the Hall-ICs built into the regulator motor and the power window ECUs to detect the window position, jamming and catching.*1

  3. SYSTEM FUNCTION

    The power window control system has the following functions:

    Function Outline
    Manual up and down function Function that causes the window to go up while the power window switch is being pulled halfway up and to go down while it is being pushed halfway down. The window stops as soon as the switch is released.
    Auto up and down function (for All Door)*1 Function that enables the window of each door to be fully opened or closed by one full pull or push of the power window regulator master switch assembly, power window regulator switch assembly or rear power window regulator switch assembly.
    Auto up and down function (for Driver Door Only)*2 Function that enables the window of each door to be fully opened or closed by one full pull or push of the power window regulator master switch assembly, power window regulator switch assembly.
    Window lock function

    • Function that disables the power window regulator switch assembly and rear power window regulator switch assembly operations when the window lock switch is pressed.

    • The power window regulator switch assembly and rear power window regulator switch assembly can be operated when the window lock switch is pressed again.
    Jam protection function (for All Door)*1 Function that automatically stops the power window and moves it downward if a foreign object gets jammed in the door window during auto up or manual up operation.
    Jam protection function (for Driver Door Only)*2 Function that automatically stops the power window and moves it downward if a foreign object gets jammed in the door window during auto up or manual up operation.
    Catch protection function (All Door)*1 Function that automatically stops the power window if a foreign object gets caught in the door window during auto down or manual down operation.
    Catch protection function (for Driver Door Only)*2 Function that automatically stops the power window if a foreign object gets caught in the door window during auto down or manual down operation.
    Remote control function Function that allows the power window regulator master switch assembly to control manual and auto up and down operations of the front passenger door window and rear door windows.
    Key-off operation function (for All Door)*1

    • Function that makes it possible to operate all power windows for approximately 43 seconds after the ignition switch is turned off when the driver door or front passenger door has not been opened.

    • When approximately 43 seconds have elapsed, or the driver door or front passenger door is opened after the ignition switch is turned off, the key-off operation function will be disabled.

    Tech Tips

    Even if the driver door or passenger door is opened during automatic window operation while the key-off operation function is on, the window will continue operating.
    Key-off operation function (for Driver Door Only)*2

    • Function that makes it possible to operate driver door power windows for approximately 43 seconds after the ignition switch is turned off when the driver door or front passenger door has not been opened.

    • When approximately 43 seconds have elapsed, or the driver door or front passenger door is opened after the ignition switch is turned off, the key-off operation function will be disabled.

    Tech Tips

    Even if the driver door or passenger door is opened during automatic window operation while the key-off operation function is on, the window will continue operating.
    Fail-safe

    • Function to disable part of the power window control system functions if the pulse sensor in the power window regulator motor has a malfunction.

    • The auto up and down function and remote control function are disabled.
