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.
V Bus
Bus 2
Bus 3
Bus 5
Sub Bus 1 (w/ Power Back Door System)
Tip:The CAN communication system connects to other networks via ECUs that function as a gateway.
Local Bus (w/ Pre-crash Safety System)
