SLIDING ROOF SYSTEM


  1. SYSTEM CONTROL


    1. The sliding roof system has following functions:

      Function Outline
      Manual Open-and-close This function opens or closes the sliding roof while the open switch or close switch is pressed for 0.3 seconds or less. The sliding roof stops as soon as the switch is released.
      One-touch Auto Open

      • This function opens the sliding roof up to the comfort stop position when the open switch is pressed for 0.3 seconds or more.

      • To suppress wind noise, this function stops opening the roof at the comfort stop position. By pressing the open switch once again, the sliding roof can be fully opened.
      One-touch Auto Close This function fully closes the sliding roof when the close switch is pressed for 0.3 seconds or more.
      Manual Tilt Up-and-down This function tilts up or down the sliding roof while the up switch or down switch is pressed for 0.3 seconds or less. The sliding roof stops as soon as the switch is released.
      One-touch Auto Tilt Up This function fully tilts up the sliding roof when the up switch is pressed for 0.3 seconds or more.
      Jam Protection The jam protection function automatically stops the sliding roof and moves it open half way (or to the fully tilted up position) if a foreign object gets jammed in the sliding roof during close or tilt down operation.
      Key-off Operation The key-off operation function makes it possible to operate the sliding roof for approximately 45 seconds after the power switch is turned to on (ACC) or off, if the front door is not opened.
      Sliding Roof Open Warning When the power switch is turned from on (IG) to off and the driver door is opened with the sliding roof 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.

      Tech Tips


      • The sliding roof ECU memorizes the initial position of the sliding roof. This memory is not cleared if the battery terminals are disconnected. However, initialization is necessary after the sliding roof drive gear sub-assembly is replaced.

      • After replacing the sliding roof drive gear sub-assembly, the sliding roof will not operate correctly. In this case, the sliding roof position must be initialized as described below:


        • Keep pressing the sliding roof switch (down) or (close) until initialization completes. This will enable the sliding roof ECU to start initializing and perform the tilt up, tilt down, open and close operations of the sliding roof in sequence.

        • Keep the switch pressed for 1 second after the tilt up operation is completed.

        • The sliding roof ECU performs the tilt down, open and close operations.

        • The initialization process ends when the close operation is completed.

      • Keep the tilt-up or slide close switch pressed during initialization. If the tilt up or close switch is released during initialization, the system will not be able to complete initialization. If this occurs, the aforementioned steps must be performed again.

      • For details, refer to the Repair Manual.

    2. Jam Protection Function


      1. To control the jam protection function, the sliding roof ECU monitors the amount of movement and judges jamming of the sliding roof based on the pulse signals from Hall IC 1, and the movement direction of the sliding roof from the phase difference between the pulses from Hall IC 1 and Hall IC 2.

  2. OPERATION


    1. Outer Slide


      1. When the slide shoes (lift link) move rearward from the sliding roof fully closed state, the pins on the brackets slide along the guide grooves of the lift link. The brackets move the sliding roof glass up (tilted up state) in accordance with the profile of the guide groove where the guide pin slides.

      2. When the slide shoes (lift link) move rearward from the sliding roof tilted up state, the pins on the brackets slide along the guide grooves of the lift link. The brackets move the sliding roof glass further up in accordance with the profile of the guide groove where the guide pin slides. When the pins reach the front end of the guide grooves, the brackets and slide shoes (lift link) move rearward while holding the sliding roof glass up.
