NAVIGATION SYSTEM(for HDD) PRECAUTION


  1. IGNITION SWITCH EXPRESSIONS


    1. The type of ignition switch used on this model differs according to the specifications of the vehicles. The expressions listed in the table below are used in this section.

      Expression

      Ignition Switch

      (Position)

      Engine Switch

      (Condition)
      Ignition Switch off LOCK Off (Lock)
      Ignition Switch ACC ACC On (ACC)
      Ignition Switch ON ON On (IG)
      Engine Start START On (Start)

  2. PRECAUTION FOR DISCONNECTING CABLE FROM NEGATIVE BATTERY TERMINAL

    Note

    After the ignition switch is turned off, the navigation ECU sub-assembly requires approximately a minute to record various types of memory and settings. As a result, after turning the ignition switch off, wait a minute or more before disconnecting the cable from the negative (-) battery terminal.

  3. PRECAUTIONS FOR NAVIGATION ECU SUB-ASSEMBLY


    1. A hard disc (HDD [Hard Disk Drive]) is built into the navigation ECU sub-assembly to store map and other data, and is used for the navigation system. Therefore, care must be taken for the following points when handling:

      A00YUBIC02
      *1 Hard Disc *2 Navigation ECU Sub-assembly
      *a Example - -

      1. When it is necessary to replace the navigation ECU sub-assembly, be sure to replace it with a new one.

        Note

        If a used navigation ECU sub-assembly is installed as a replacement part, the customer's HDD will not be recognized.

      2. Do not apply any vibration or shock to the navigation ECU sub-assembly.

        Note


        • Do not drop or subject the navigation ECU sub-assembly to severe impacts.

        • Do not use the navigation ECU sub-assembly if it has been dropped or subjected to a severe impact.

        • Do not store the navigation ECU sub-assembly without the HDD installed. (Only remove the HDD from the navigation ECU sub-assembly when the replacement navigation ECU sub-assembly or HDD is ready.)

      3. Do not remove the navigation ECU sub-assembly if there is a risk that condensation may occur.

        Note

        If the temperature of the navigation ECU sub-assembly changes rapidly, condensation may occur inside the unit. This may cause a malfunction of the HDD. Therefore, when the navigation ECU sub-assembly is removed from the instrument panel, it needs to be kept inside the vehicle or in an environment with an equivalent temperature and humidity.

      4. Take measures to prevent static electricity.

        Note

        Touching the terminals of a connector can cause static electricity to be transmitted to the internal circuits. This may cause a malfunction of the HDD.

      5. Keep the navigation ECU sub-assembly away from magnets or magnetized items.

        Note

        Keep the navigation ECU sub-assembly away from speakers, motors, magnetized tools and other magnetic items.

  4. PRECAUTIONS FOR HARD DISC (HDD [HARD DISK DRIVE])


    1. Map and other data for the navigation system is stored on the hard disc. Make sure to follow the following instructions when replacing the HDD:

      Note

      Data downloaded by the customer may be stored on the HDD. This data will be lost when the HDD is replaced. Make sure to warn the customer that their data will be lost and obtain their consent prior to replacing the HDD.


      1. The HDD must only be replaced with a new one. Do not attempt to install a used HDD from another vehicle.

        Note

        The navigation ECU sub-assembly can recognize only a new HDD.

      2. A00YULCC01
        *a Example
        *b CORRECT
        *c INCORRECT

        Do not touch the HDD cover.

        Note

        When removing or installing the HDD, only hold it by the areas shown in the illustration.

      3. Do not apply any vibration or shock to the HDD.

        Note


        • Do not drop or subject the HDD to severe impacts.

        • Do not use the HDD if it has been dropped or subjected to a severe impact.

        • Do not store the HDD by itself if it has been removed from the navigation ECU sub-assembly. (Only remove the HDD from the navigation ECU sub-assembly when the replacement navigation ECU sub-assembly or HDD is ready.)

      4. Do not remove the HDD if there is a risk that condensation may occur.

        Note

        If the temperature of the HDD changes rapidly, condensation may occur inside the unit. This may cause a malfunction of the HDD. Therefore, when the navigation ECU sub-assembly is removed from the instrument panel, it needs to be kept inside the vehicle or in an environment with an equivalent temperature and humidity.

      5. Take measures to prevent static electricity.

        Note

        Touching the terminals of a connector can cause static electricity to be transmitted to the internal circuits. This may cause a malfunction of the HDD.

      6. Keep the HDD away from magnets or magnetized items.

        Note

        Keep the HDD away from speakers, motors, magnetized tools and other magnetic items.

      7. Inspect after HDD replacement.

        Note

        Make sure to perform Check hard disc in Operation Check to confirm that there are no HDD abnormalities after removal or installation.
