    Tip:

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

    • The central gateway ECU functions as a gateway between the V bus, bus 2, bus 3 and bus 5.

    • 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.
