ROOF SUNSHADE SYSTEM DETAILS


  1. SYSTEM CONTROL


    1. The roof sunshade system has following functions:

      Function Outline
      Manual Open-and-close This function opens or closes the roof sunshade while the open switch or close switch is pressed for 0.3 seconds or less. The roof sunshade stops as soon as the switch is released.
      One-touch Auto Open-and-close This function fully opens or closes the roof sunshade when the open switch or close switch is pressed for 0.3 seconds or more.
      Jam Protection The jam protection function automatically stops the roof sunshade and moves it open half way if a foreign object gets jammed in the roof sunshade during close operation.

      Tech Tips


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

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


        • Keep pressing the roof sunshade close switch until initialization is completed. This will enable the roof sunshade ECU to start initializing and perform the open and close operations of the roof sunshade in sequence.

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

      • Keep the close switch pressed during initialization. If the 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 roof sunshade ECU monitors the amount of movement and judges jamming of the roof sunshade based on the pulse signals from Hall IC1, and the moving direction of the roof sunshade from the phase difference between the pulses from Hall IC1 and Hall IC2.
