Sliding Roof System: Initialization

1. Turn the engine switch on (IG)
2. Press and hold the sliding roof push switch until the following operations are completed.
   1. The sliding roof moves to the tilt fully open position and remains for 1 second.
   2. Tilt down operation starts After the roof is fully closed, it starts sliding to open
   3. After the roof slides to the fully open operation, the operation stops and then the roof closes to the fully closed position.

      Switch Condition	Sliding Roof Position
      [1]	Over stroke position
      [2]	Slide fully open position [A]
      [3]	Slide stop position [B] (Comfort stop position)
      [4]	Slide stop position [C]
      [5]	Slide stop position [D]
      [6]	Slide stop position [E]
      [7]	Slide stop position [F]
      [8]	Slide stop position [G]
      [9]	Fully closed position [H]
      [10]	Tilt fully open position
      [11]	Fully closed → comfort stop position Open position → fully closed

3. Check that the operation works normally with auto operation.
   NOTE:

   • If the battery voltage changes during initialization, the sliding roof ECU may not be initialized normally.
   • Do not apply excessive loads to the vehicle during initialization by performing operations such as locking the doors or cranking the engine.
   • Do not turn the engine switch off during initialization.
   • Do not move the vehicle during initialization.
   • Do not apply strong impacts to the vehicle during initialization by performing operations such as closing the doors forcefully.

HINT:

The following operation should be used when the sliding roof cannot be fully closed.

1. If the jam protection function is operated repeatedly, the fail-safe function will not activate. To return to the normal condition, push the sliding roof switch assembly at position [11] for 10 seconds or more

HINT.

The following operation should be used if it is necessary to clear the learned position of the sliding roof

1. The learned position of the sliding roof is stored in an EEPROM Even after the cable has been disconnected from the negative (-) battery terminal, the position will remain stored in memory In order to clear the position, perform the following steps
   1. Turn the engine switch on (IG)
   2. Make sure that there is no foreign matter on the guide rails.
   3. Make sure that the guide rails are not deformed.
   4. Set the sliding roof switch to position [9] and confirm that the sliding roof does not reverse*1
   5. After the sliding roof stops, to prevent the sliding roof from moving, quickly turn the sliding roof switch to position [1] and hold it there for 10 seconds or more*2
   6. Clearing the learned position of the sliding roof is complete when the sliding roof moves slightly to the opening direction.
   7. To confirm that the learned position has been cleared, make sure that auto operation does not start when the sliding roof switch is set to any position from [2] to [8].
   8. Start initialization of the sliding roof drive gear sub-assembly

      HINT

      *1: If the sliding roof reverses due to jam protection operation, it can be moved to fully closed position by pressing and holding the sliding roof switch [11] Make sure to set the sliding roof to the fully closed position before proceeding to the next step

      *2: If the sliding roof moves while rotating the sliding roof switch, restart the Forced Initialization Clearing procedure from the first step
