        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

      C343156E04
      C347296E02

    4. Bus 3

      C348134E01

    5. Bus 5

      C343159E05
      C343160E04

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

      C280389E06
      Tip:

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

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