SLIDING ROOF SYSTEM


  1. SYSTEM CONTROL


    1. The sliding roof system has the following functions:

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

      • Opens the sliding roof up to the fully opened position when the open switch is pressed for 0.3 seconds or more.

      • To suppress wind noise, this function stops opening the roof at an appropriate stop position. By pressing the open switch once again, the sliding roof can be fully opened.
      One-touch Auto Close Fully closes the sliding roof when the close switch is pressed for 0.3 seconds or more.
      Manual Tilt Up-and-down Tilts the sliding roof up or down when the up switch or down switch is pressed for less than 0.3 seconds. The sliding roof stops as soon as the switch is released.
      One-touch Auto Tilt Up-and-down Fully tilts the sliding roof up or down when the up switch or down switch is pressed for 0.3 seconds or more.
      Jam Protection The jam protection function automatically stops the sliding roof and opens it almost fully 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 43 seconds after the power switch has been turned on (ACC) or off, if the driver door is not opened.
      Key-linked Operation*

      • When the key cylinder in the driver door is turned and held in the unlock position for 2.5 seconds or more, the sliding roof control ECU activates the sliding roof motor to open the sliding roof while the key cylinder is turned.

      • Similarly, turning and holding the driver door key cylinder in the lock position will cause the sliding roof to close.
      Transmitter-linked Operation*

      • When the certification ECU (smart key ECU assembly) receives an unlock signal from the key continuously for 4 seconds or more via the door control receiver, the sliding roof control ECU opens the sliding roof.

      • Similarly, when the certification ECU (smart key ECU assembly) receives a lock signal from the key continuously for 4 seconds or more via the door control receiver, the sliding roof control ECU closes the sliding roof.
      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, a warning message appears on the multi-information display, the multi buzzer sounds and the master warning light blinks.

      *: Customizable parameters can be configured by means of the customized body electronics system. For details, refer to the Repair Manual.

      Tech Tips

      The sliding roof control 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. 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 IC1 and the movement direction of the sliding roof from the phase difference between the pulses from Hall IC1 and Hall IC2.
