POWER WINDOW CONTROL SYSTEM (for TMMK Made) DETAILS


  1. SYSTEM CONTROL


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

      Function Outline Customizable*
      Power Up-and-down (All Doors) 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. Standard (Not Customizable)
      One-touch Auto Up-and-down (Front Doors) 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. Standard (Not Customizable)
      Jam Protection (Front Doors) The jam protection function automatically stops the power window and moves it downward if an object gets jammed in the door window glass during one-touch auto-up operation or power up operation. Standard (Not Customizable)
      Catch Protection (Front Doors) The catch protection function automatically stops the power window if an object gets caught by the door window glass during one-touch auto-down operation or power down. Standard (Not Customizable)
      Soft Stop (Front Doors) During an up operation of the power window, the power window ECU stops the current to the power window motor right before the door glass is fully closed. Standard (Not Customizable)
      Remote Control (All Doors) The power window regulator master switch assembly can control the up-and-down operation of the windows. Standard (Not Customizable)
      Window Lock Operation of the 3 passenger windows is disabled when the window lock switch is pressed. Standard (Not Customizable)
      Key Off Operation

      • Makes it possible to operate the power windows for approximately 43 seconds after the engine switch is turned off (Lock), 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, the windows cannot be operated.

      • 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.

      		 Standard (Not Customizable)

      • *: Customizable settings can be turned on or off. For details, refer to the Repair Manual.

      Tech Tips

      The ECU built into each driver and front passenger door power window motor stores the initial position of its door window glass. The initial position is not cleared even if the battery terminals, fuses or power window motor connector is disconnected. However, after removing or reinstalling window components, or replacing the power window regulator sub-assembly or power window regulator motor, 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 an 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.

        Situation Operation
        During auto up operation Down operation until door window glass downward movement of 125 mm (4.93 in.) is reached, or 2.5 seconds elapse
        During manual up operation Down operation until door window glass downward movement of 25 mm (0.0984 in.) is reached, or 2.5 seconds elapse

        Tech Tips

        After the jam protection function has operated when an auto up or manual up operation was performed, the jam protection function will not operate if the manual up operation is performed again within approximately 4 seconds.

    3. Catch Protection Function


      1. A catch protection function automatically stops the power window if an object gets caught by the door window glass during one-touch auto down operation and power down operation.

    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 window glass is in the stop position by monitoring the changes in the output signal from the pulse sensor (Hall IC). The judgment method is as follows:

        B0001MTE01

    5. Power Window Regulator Motor Assembly


      1. The magnet and Hall IC in the power window motor are used in the power window jam protection function and catch protection function.

        B000282E01
        Text in Illustration
        *a Hall IC *b Worm Gear
        *c Magnet - -

      2. The Hall IC converts the changes in magnetic flux that occur through the rotation of the magnet into pulse signals and outputs them to the ECU built-into the power window motor.

      3. To control the jam protection function and catch protection function, the ECU determines the amount of movement and determines if the window glass is jamming based on the pulse signal A from the Hall IC; The direction of the window glass movement is determined based on the phase difference between the pulses of Hall IC signals A and B.

        B00026GE12

  2. FAIL-SAFE


    1. If the Hall IC in the power window motor (driver and front passenger) malfunctions, some power window functions will be prohibited for fail-safe mode:


      1. The power window operates when the 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.
