With CAN-C, the terminal resistors are incorporated
in ECU. Resistors with approximately 120 ohms is
used for the dominant ECU, and that with 4.7
kiloohms is used for the non-dominant ECU.

Dominant ECU: ETACS-ECU and engine ECU
Non-dominant ECU: ECU and sensor on CAN-C
network, excluding ETACS-ECU and engine
ECU
To the CAN bus line, ECU, sensor, and data link
connector are connected as follows for each
network.

The CAN communication system is described below.
Each ECU communicating with CAN periodically
sends several sensors’ information on CAN bus as
data frame (called periodical sending data). For
further details, consult the data frame section.
ECUs requiring data on CAN bus can receive data
frames sent from each ECU simultaneously.
The data sent from each ECU conducting CAN
communication is transmitted at 10-1000 msec
interval depending on necessity of data.
