(4) For BEAN, if 2 communication buses are open at the position as shown in the illustration, DTC of ECU communication stop between
those 2 buses is output.
(d) Difference of CAN, BEAN and AVC-LAN
(1) The CAN, BEAN and AVC-LAN protocols have set guidelines for data. The guidelines include communication speed, type of
communication wire, drive type and data length. These guidelines are established to facilitate ECU data communication.

The CAN uses the multi star style bus connection. The 2 junction connectors are connected with a main bus line. The junction
connector extends a sub bus line and enables communication between all the connected ECUs.
(2) A single, Automobile Vinyl (AV) wire is used for BEAN communication. A braided-pair wire is used for CAN and AVC-LAN
communication.
