    Tech Tips


    • 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 (for LHD)

    A01EYJ7E02
    A01ETJSE02

    Tech Tips

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