System Description [12/2019 - ]

  1. PANORAMIC MOON ROOF SYSTEM DESCRIPTION 
    1. The panoramic moon roof system controls the sliding roof operation using the sliding roof ECU (sliding roof drive gear assembly) and roof sunshade ECU (sliding roof drive gear assembly). Operating the map light assembly results in electrical power being transmitted to the sliding roof ECU (sliding roof drive gear assembly) and roof sunshade ECU (sliding roof drive gear assembly).
  2. FUNCTION OF MAIN COMPONENT 

    The panoramic moon roof system consists of the following components:

    Component Outline
    Sliding roof ECU (Sliding roof drive gear assembly) The sliding roof ECU (sliding roof drive gear assembly) controls the rotational direction of the motor, which tilts or slides the sliding roof glass.
    Roof sunshade ECU (Sliding roof drive gear assembly) The roof sunshade ECU (sliding roof drive gear assembly) controls the rotational direction of the motor, which slides roof sunshade.
    Map light assembly The map light assembly outputs operation signals to the sliding roof ECU (sliding roof drive gear assembly) and roof sunshade ECU (sliding roof drive gear assembly).
  3. SYSTEM FUNCTION 

    The panoramic moon roof system has the following functions:

    Function Outline
    Manual slide open and close function
    • For sliding roof:

      This function causes the sliding roof to open (or close) when the sliding roof switch is slid backward (or forward) for a maximum of 0.3 seconds. The sliding roof stops as soon as the switch is released.

    • For roof sunshade:

      This function causes the roof sunshade to open (or close) when the roof sunshade switch is slid backward (or forward) for a maximum of 0.3 seconds. The roof sunshade stops as soon as the switch is released.
    Auto slide open and close function
    • For sliding roof:

      This function causes the sliding roof to fully opened (or fully closed) position when the sliding roof switch is slid backward (or forward) for a minimum of 0.3 seconds.

    • For roof sunshade:

      This function causes the roof sunshade to be fully opened (or closed) when the roof sunshade switch is slid backward (or forward) for a minimum of 0.3 seconds.
    Manual tilt up and down function For sliding roof:
    This function causes the sliding roof to tilt up (or tilt down) when the sliding roof switch is pressed for a maximum of 0.3 seconds. The sliding roof stops as soon as switch is released.
    Auto tilt up function For sliding roof:
    When the sliding roof is not fully tilted up, this function causes the sliding roof to reach the fully tilted up position when the sliding roof switch is pressed for a minimum of 0.3 seconds.
    Jam protection function
    • For sliding roof:

      The jam protection function automatically stops the sliding roof and moves it open halfway (or fully tilts up) if foreign matter gets jammed in the sliding roof during a close or tilt down operation.

    • For roof sunshade:

      The jam protection function automatically stops the roof sunshade and moves it to the halfway open or fully open position if foreign matter gets jammed in the roof sunshade during a close operation.
    Key-off operation function The key-off operation function makes it possible to operate the sliding roof for approximately 45 seconds after the ignition switch is turned from ON to off, if the front doors are not opened.
    Sliding roof open warning function When the ignition switch is turned from ON to off and the driver door is opened with the sliding roof open, a warning message appears on the multi-information display.
