Initialization [10/2015 - ]

  1. INITIALIZE POWER WINDOW CONTROL SYSTEM (ALL DOORS) 
    NOTE:
    • When a door window regulator assembly, power window regulator motor assembly, door glass or door glass run is reinstalled or replaced, the power window control system must be initialized. Functions such as the auto up and down function, jam protection function, remote control function, key-linked function, wireless transmitter-linked function, catch protection function, key-off operation function and window open warning function will not operate if initialization is not performed.
    • When a power window regulator motor assembly is replaced, DTC B2313 is stored. Clear the DTC after initialization.

      Refer to DTC CHECK / CLEAR [10/2015 - ] 

    • When performing initialization, do not perform any other procedures.
    • When performing initialization, use the power window switch of each door to initialize each door window.
    • Make sure to park the vehicle and turn off all electrical systems before performing initialization. Initialization will be canceled if the vehicle is driven during initialization.
    • Make sure not to hit, strike or vibrate the door window glass during initialization because the vehicle is learning the sliding resistance of the door window glass.
    • Make sure not to turn the engine switch on (IG) or off during initialization.

    HINT: 

    If the battery has been replaced, it is not necessary to initialize the power window regulator motor assembly.

    HINT: 

    • If the battery has been replaced, it is not necessary to initialize the power window regulator motor assembly.
    • If initialization does not complete properly, the LIN communication system may be malfunctioning.

      Refer to HOW TO PROCEED WITH TROUBLESHOOTING [10/2015 - ]

    1. Perform initialization according to the table below.
      Condition of Power Window Proceed to
      Initialization method when a power window regulator motor assembly has been replaced with a new one. Procedure A
      • Initialization method for when a power window regulator motor assembly has been removed/installed or a door glass and/or door glass run, etc. have been removed/installed or replaced with new ones.
      • Initialization method for when the window cannot fully open via a down operation (door glass remains visible).
      • Initialization method for when the door glass cannot be fully closed (erroneously operates in reverse) after initialization.
      • Initialization method for when the door glass cannot be fully opened (erroneously stops) after initialization.
      • Initialization method for when instructions to perform initialization appear in other troubleshooting flowcharts.

        HINT: 

        Use this procedure if a power window regulator motor assembly is being reused.

      		 Procedure B
      Initialization method when a reverse rotation malfunction occurs due to a sliding resistance change resulting from adjustment etc. Procedure C
    2. Procedure A

      Perform registration of the door glass position (fully closed, fully open) and sliding resistance learning.

      • *: Even if the door glass is in the fully open position before performing step 3, perform the down operation for 1 second or more.
    3. Procedure B

      Reset the door glass position, perform window position initialization (fully closed, fully open) and sliding resistance learning.

      • *1: The door glass stopped position is the fully open position stored in the ECU.
      • *2: After performing step 7, release the switch, and then perform an auto down operation.
      • *3: After completing initialization, check that the power window can be fully closed using an auto up operation.
      • If the initialization is not completed properly, the LIN communication system may be malfunctioning

      HINT: 

      If the initialization is not completed properly, the LIN communication system may be malfunctioning

      Refer to HOW TO PROCEED WITH TROUBLESHOOTING [10/2015 - ]

    4. Procedure C

      Perform sliding resistance learning.

      HINT: 

      • Do not release the switch during step 4, 5 or 6.
      • If the jam protection function or catch protection function continue to operate even after performing steps 4, 5 and 6, perform the procedure again from step 3.
