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, which is mounted on the driver door, and the power window regulator switches, which are mounted on the front passenger door and 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:

    Power Window Regulator Master Switch Assembly

    • Controls power window operation for all seats.

    • When window lock switch is pressed, window operation will be possible only for driver door power window.

    • Front Passenger Door

    • Rear LH Door

    • Rear RH Door

    • Located on front passenger door and rear doors.

    • Each switch controls window operation for its respective window.

    Power Window Regulator Motor Assembly


    • Driver Door

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

    • Uses Hall-IC in regulator motor with ECU to detect window position and jamming.

    • Rear RH Door

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

  3. SYSTEM FUNCTION

    The power window control system has the following functions:

    Function Outline
    Manual up and down function

    • For driver door:

      Function that causes the window to go up while the power window regulator master switch assembly is being pulled halfway up and to go down while pushed halfway down. The window stops as soon as the switch is released.

    • For passenger door:

      Function that causes the window to go up while the power window regulator switch assembly is being pulled up and to go down while pushed down. The window stops as soon as the switch is released.
    Driver door auto up and down function Function that enables the driver door window to be fully opened or closed by one full pull or push of the power window regulator master switch assembly.
    Window lock function

    • Function that disables power window operation (for front passenger door, rear LH door and rear RH door) when the window lock switch is pressed.

    • The power window operation (for front passenger door, rear LH door and rear RH door) can be operated when the window lock switch is pressed again.
    Jam protection function (for driver door) Function that automatically stops the power window and moves it downward if a foreign matter gets jammed in the door window during auto up or manual up operation.
    Remote control function Function that allows the power window regulator master switch assembly to control manual up and down operation of the front passenger door window and rear door windows.
    Key-off operation function

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

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

    Tech Tips

    If the driver door or front passenger door is opened during automatic window operation while the key-off operation function is on, the window will stop operating.
    Key-linked open and close*1

    • When the key is not inside the vehicle, the driver door is unlocked, and the key inserted into the driver door key cylinder is turned and maintained in the lock position for 1.5 seconds or more, the main body ECU (multiplex network body ECU) sends operation permission signal to the power window ECU in the power window regulator motor assembly LH (for driver door) that receives signal controls the power window regulator motor to close the driver door power window.

    • Similarly, when the driver door is locked, turning and maintaining the driver door key in the unlock position for 1.5 seconds or more will cause the driver door power window to open.
    Wireless transmitter-linked open*1,*2 When the main body ECU (multiplex network body ECU) receives unlock signal from the electrical key transmitter for 2.4 seconds or more, the main body ECU (multiplex network body ECU) sends operation permission signal to the power window ECU in the power window regulator motor assembly LH (for driver door) that receives signal controls the power window regulator motor to open power window.
    Diagnosis Function that allows diagnosis of the power window control system if the power window ECU (built into power window regulator motor assembly LH (for driver door)) detects a malfunction in the system. If a malfunction is detected, the power window ECU will illuminate the LED on the power window regulator master switch assembly to inform the driver of the malfunction.
    Fail-safe

    Function that disables a part of power window functions if the pulse sensor in the power window motor has a malfunction.

    Auto up and down function is disabled.

    • *1: This function is set through the customize function, as it is off by default

    • *2: w/ Daytime Running Light Control
