POWER WINDOW CONTROL SYSTEM


  1. FUNCTION


    1. The power window control system has the following functions:

      Function Outline
      Power Up-and-down This function causes the window to open or close while the power window regulator master switch assembly or power window regulator switch assembly is being pulled halfway up or pushed halfway down. The window stops as soon as the switch is released.
      One-touch Auto Up-and-down The one-touch auto up-and-down function enables the window to be fully opened or closed at a touch of the power window regulator master switch assembly or power window regulator switch assembly.
      Jam Protection The jam protection function automatically stops the power window and moves it downward if a foreign object gets jammed in the door window glass during one-touch auto-up operation or power up operation.
      Catch Protection Catch protection function automatically stops the power window if a foreign object gets jammed in the window during one-touch auto-down operation or power down.
      Remote Control The power window regulator master switch assembly can control the up-and-down operation of all power windows.
      Window Lock

      • Operation of the front passenger window and rear windows is disabled when the window lock switch is on.

      • Illumination of the power window regulator switches, except the one for the driver door, are turned off to inform the occupants that the windows cannot be operated.
      Key Off Operation

      • Makes it possible to operate the power windows for approximately 45 seconds after the power switch is turned off, if either front door is not opened.

      • If the window lock switch is off, the windows can be operated using any of the power window regulator switch assemblies. If the window lock switch is on, only the power window regulator master switch assembly can be used to operate the windows (remote operation remains possible).

      Key-linked Up-and-down*

      		When the electrical key transmitter sub-assembly is not in the interior detection area, the driver door is locked, and the mechanical key in the driver door is turned and maintained in the lock direction for 1.5 seconds or more, the main body ECU (multiplex network body ECU) activates the power window motors to raise all door windows while the mechanical key is turned. Similarly, when the driver door is unlocked, turning and maintaining the driver door key cylinder in the unlock direction for 1.5 seconds or more will cause all door windows to be lowered.

      Transmitter-linked down*

      		When the certification ECU (smart key ECU assembly) receives an unlock signal from the transmitter for longer than 3 seconds, the main body ECU (multiplex network body ECU) controls the power window motors in accordance with the signal to open the windows. Similarly, when the certification ECU (smart key ECU assembly) receives a lock signal from the transmitter for longer than 3 seconds, the main body ECU (multiplex network body ECU) controls the power window motors in accordance with the signal to close the windows.
      Power Window Glass Open Warning When the power switch is turned from on (IG) to off and the driver door is opened with the power window glass open, the buzzer in the combination meter assembly sounds once. Then, a warning message appears on the multi-information display and the master warning light blinks.
      Customization The on or off setting of some functions can be performed using the Global TechStream (GTS). For details, refer to the Repair Manual.

      *: The function setting can be changed using customized body electronics system.

      Tech Tips

      The ECU built into each power window regulator motor assembly stores the initial position of its door window glass. The initial position is not cleared even if battery terminals, fuses or the power window regulator motor assembly connector is disconnected. However, after removing or reinstalling window components, or replacing the power window regulator assembly or power window regulator motor assembly, the stored initial position data must be cleared and/or initialization must be performed. For details, refer to the Repair Manual.

    2. Jam Protection Function


      1. The jam protection function automatically stops the power window and moves it downward if a foreign object gets jammed in the door window glass during one-touch auto up operation or power up operation.

      2. The operation of the jam protection function is as described below.

        Door Window Position from Full Close Operation
        200 mm (7.87 in.) or more Down operation of 125 mm (4.93 in.) or 2.5 seconds
        200 mm (7.87 in.) or less Down operation until door window glass downward movement of 200 mm (7.87 in.) is reached, or 5 seconds elapse.

    3. Catch Protection Function


      1. The catch protection function automatically stops the power window if a foreign object gets caught in the window during a down operation.

      2. The power window ECU determines if a foreign object gets caught according to changes in the output signal from the pulse sensor (Hall IC). The judgment method is as follows:

    4. Soft Stop Function


      1. During an up operation of the power window, the soft stop function stops the current to the power window motor right before the door glass is fully closed. This reduces the load on the door glass outer weatherstrip.

      2. The power window ECU determines if the door glass stop position is detected according to changes in the output signal from the pulse sensor (Hall IC). The judgment method is as follows:

  2. FAIL-SAFE


    1. If a Hall IC in the power window regulator motor malfunctions, some power window functions will be prohibited in fail-safe mode


      1. Each power window only operates when the corresponding power window switch is fully pushed down or pulled up and held in that position.

  3. DIAGNOSIS


    1. If a power window ECU detects a malfunction in the power window control system, a Diagnostic Trouble Code (DTC) is stored in memory.


      1. The DTCs can be read using the Global TechStream (GTS). For details, refer to the Repair Manual.
