SLIDING ROOF SYSTEM INITIALIZATION


  1. INITIALIZE SLIDING ROOF DRIVE GEAR SUB-ASSEMBLY

    Note


    • Before starting this operation, make sure that the guide rails are not deformed and there is no foreign object on the guide rails.

    • When the sliding roof glass is adjusted or removed/installed, or the sliding roof drive gear assembly is replaced, the sliding roof ECU (sliding roof drive gear) must be initialized (pulse sensor initial position setting). Failure to initialize could result in displacement of the roof glass set position, defects in the automatic systems or the roof glass moving in the reverse direction.

    • During initialization, do not apply a physical shock, such as opening/closing a door or driving the vehicle at 5 km/h (3 mph) or more, to the vehicle and do not perform the following electrical operations:


      1. Cranking the engine

      2. Turning the engine switch from on (IG) to off

      3. Operating the power window switches

      4. Operating the window defogger switch

      5. Operating the blower switch

      6. Locking/Unlocking a door

      7. Operating the headlight dimmer switch

      8. Operating the power seat switch

    Tech Tips

    The sliding roof switch assembly is attached to the map light assembly.


    1. Initialization

      Tech Tips

      Perform initialization according to the table below.

      Condition of Sliding Roof Proceed to
      Auto slide open and close/tilt up and down function does not operate. Procedure A
      Automatically moves, but the sliding roof glass does not stop at the right position (displacement occurs). Or, the sliding roof glass moves in the reverse direction during tilt down operation. Procedure B
      Automatically moves, but the sliding roof glass moves in the reverse direction during slide close operation. Procedure C

      1. Procedure A


        1. Turn the engine switch on (IG).

        2. Fully close the sliding roof glass and release the sliding roof switch.

        3. Press and hold the UP switch.

        4. Sliding roof glass moves in the following order: tilt up → 1 second pause → tilt down → slide open → slide closed

        5. After stopping the sliding roof glass in the fully closed position, release the switch.

          Note

          Press and hold the UP switch until step 5 is completed. If the switch is released before step 5 is completed, repeat the operation starting at step 2.

        6. Make sure that the sliding roof works automatically in the normal manner.

      2. Procedure B


        1. Turn the engine switch on (IG).

        2. Press the UP switch to move the sliding roof glass into the fully tilted up position and then release the UP switch.

          Tech Tips


          • If the sliding roof glass cannot be fully tilted up due to misalignment of the roof glass, press and hold the CLOSE switch until the sliding roof glass stops closing, and then press and hold the UP switch until the sliding roof glass stops tilting up.

          • If the sliding roof glass moves in the reverse direction while it is being closed, repeatedly tap the CLOSE switch at short intervals to fully close the sliding roof glass. When the sliding roof glass is fully closed, press the UP switch to move the sliding roof glass into the fully tilted up position.

        3. Press and hold the UP switch again for 10 seconds to move the sliding roof glass in the following order: tilt inching motion → 1 second pause → tilt down → slide open → slide closed

        4. After stopping the sliding roof glass in the fully closed position, release the switch.

          Note


          • Press and hold the UP switch until step 4 is completed.

          • While performing step 3, if the UP switch is released before it is pressed for 10 seconds, start this step over.

          • While performing step 3, if the UP switch is released after it is pressed for 10 seconds or longer, the automatic system will not work. In such a case, perform procedure [A] to complete initialization.

        5. Make sure that the sliding roof works automatically in the normal manner.

      3. Procedure C


        1. Turn the engine switch on (IG).

        2. Press and hold the CLOSE switch to move the sliding roof glass in the following order: slide closed → move in the reverse direction → pause → start closing after approximately 10 seconds → tilt up → 1 second pause → tilt down → slide open → slide closed

        3. After stopping the sliding roof glass in the fully closed position, release the switch.

          Note


          • Press and hold the CLOSE switch until step 3 is completed.

          • While performing step 2, if the CLOSE switch is released before it is pressed for 10 seconds, start this step over.

          • While performing step 2, if the CLOSE switch is released after it is pressed for 10 seconds or longer, the automatic system will not work. In such a case, perform procedure [A] to complete initialization.

        4. Make sure that the sliding roof works automatically in the normal manner.
