BODY ELECTRICAL - MULTIPLEX COMMUNICATION
2. Communication Wire
A twisted-pair wire is used for CAN and AVC-LAN communication. A single, AV (Automobile Vinyl) wire
is used for BEAN* communication.
*: The BEAN is used in the body electrical system of the '06 Camry and some other TOYOTA models, but
is not used on the '07 Camry Hybrid model.

Single Wire Voltage Drive
This communication wire is a pair of twisted lines.
Communication is driven by applying 1.5 to 2.5 V and 2.5
to 3.5 V of voltage to the two lines in order to send a single
signal.
This system, which is called a "Differential Voltage Drive",

This communication wire is a pair of twisted lines.
Communication is driven by applying positive (+) and
negative (-) voltages to the two lines in order to send a
single signal. This system, which is called a "Differential
Voltage Drive", reduces noise.
241BE168
This is a lightweight single communication wire that
consists of a single core line surrounded by insulation.
Voltage is applied to this line in order to drive
communication, and this system is called a "Single Wire
Voltage Drive".
