ROOF SUNSHADE SYSTEM INITIALIZATION


  1. INITIALIZE ROOF SUNSHADE ECU (SLIDING ROOF DRIVE GEAR SUB-ASSEMBLY)

    Note


    • When the roof sunshade, roof sunshade ECU (sliding roof drive gear sub-assembly) or sliding roof housing is replaced or removed and installed, the roof sunshade ECU (sliding roof drive gear sub-assembly) requires initialization (pulse sensor initial position setting), as the roof sunshade position cannot be determined. If initialization is not performed, the auto slide open and close function may not operate, or the roof sunshade may move in reverse or become misaligned.

    • 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.


    1. Check the operation of the roof sunshade.

      Roof Sunshade Operation Proceed to
      Auto operation does not operate. Procedure A
      Auto operation operates normally, but the roof sunshade does not stop at the correct fully closed position. Procedure B
      Auto operation operates normally, but the roof sunshade erroneously reverses operation while sliding closed. Procedure C

      Tech Tips

      Before performing initialization, make sure that there is no foreign matter on the guide rails and the guide rails are not deformed.

    2. Procedure A (Normal initialization)


      1. Turn the power switch on (IG).

      2. Press and hold the CLOSE switch.

      3. The roof sunshade starts sliding close operation and stops at the fully closed position.

      4. After the roof sunshade stops, continue pressing the CLOSE switch for 1 second or more.

      5. Check that the roof sunshade moves slightly rearward and stops at the correct fully closed position.

        Tech Tips

        The initialization process ends when this operation completes.

    3. Procedure B (Resetting the memorized position)


      1. Turn the power switch on (IG).

      2. Press and hold the CLOSE switch until the roof sunshade stops and then release the switch.

      3. Press and hold the CLOSE switch again for 10 seconds or more.

      4. The roof sunshade starts sliding closed operation and stops at the fully closed position.

      5. After the roof sunshade stops, continue pressing the CLOSE switch for 1second or more.

      6. Check that the roof sunshade moves slightly rearward and stops at the correct fully closed position.

        Tech Tips

        The initialization process ends when this operation completes.

    4. Procedure C (Clear initialization)


      1. Turn the power switch on (IG).

      2. Press and hold the CLOSE switch until the following movements finish and then release the switch: starts sliding closed → erroneously reverses → stops operation for 10 seconds → starts sliding closed → stops at the fully closed position.

      3. Perform Procedure A.
