        Tip:

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

        • Refer to the following bus wiring diagrams for details.

    2. V Bus

      C277438E02
      C277439E01
      Tip:

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