        Tip:

        • The main body ECU (multiplex network body ECU) functions as a gateway between the bus 2 and sub bus 1.

        • The driving support ECU assembly functions as a gateway between the bus 5 and local bus.

        • Refer to the following bus wiring diagrams for details.

    2. V Bus

      C334528E02

    3. Bus 2

      C346311E02
      C346312E02

    4. Bus 3 (w/ Audio and Visual System [for Radio and Display Type])

      C343158E08

    5. Bus 5

      C346313E04
      C346314E03

    6. Sub Bus 1 (w/ Power Back Door System)

      C280389E10
      Tip:

      The CAN communication system connects to other networks via ECUs that function as a gateway.

    7. Local Bus (w/ Pre-crash Safety System)

      C343170E05

    8. Sub Bus 15
