        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

      C343156E03
      C347296E01
    4. Bus 3

      C343158E03
    5. Bus 5

      C343159E04
      C350050E01
    6. Sub Bus 1 (w/ Power Back Door System)

      C347297E02
      Tip:

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