      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

   

   

   Tip:

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

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

   

   Tip:

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