CAUTION:
  • "IAU-IBU learning", "IAU-BLE module learning" is executed in order.

    (Replacing IAU will remove all saved data. Device learning is required.)

    (Refer to Digital Key System - "LEARNING METHOD ")

  • Device learning must be performed. It is a key creation process for encrypted communication.
    • Existing smart phone key and NFC card key information linked with the previous vehicle is removed.

      (However the smart key information still remains. Use the smart key to start the engine.)

    • To re-register the smart phone key, the driver needs to perform "Digital Key Reset" from his/her smart phone.

      Only reset the smart phone key for the vehicle you would like to re-register.

    • NFC card key requires re-registration, and can be used after replacement with a new card key. (Previously used card keys cannot be reused)
