GENERAL INFORMATION

LIN refers to "Local Interconnect Network," which is a
serial

multiplex

communication

protocol*administrated by LIN consortium. A
communication circuit employing the LIN protocol
connects each ECU, and switch and sensor data can

be shared among ECUs, which enables more
reduction in wiring.

NOTE:

*: The regulations that have been decided

in detail, from software matters such as the
necessary transmission rate for communication,
the system, data format, and communication timing
control method to hardware matters such as the
harness type and length and the resistance values.

Slave ECU

Master and slave ECUs are connected to the LIN bus
lines. The master ECU is the ETACS*-ECU, and the
slave ECUs are the column switch (column-ECU), the
power window main switch and the sunroof motor
assembly. The master ECU requests these slave

ECUs to communicate each other via communication
lines.

LIN communication system is described below:

｠

The master ECU performs the master tasks and
slave tasks, and the slave ECUs perform the slave
tasks.

｠

When the master ECU performs a master task, the
header frame which stores information to call
certain slave tasks (ECU) is transmitted at regular
intervals.

｠

When the master ECU and slave ECU perform a
slave task, the ECU called by the header frame

transmits the response frame which stores data
used for control.

｠

A header and response collectively are called as a
message frame, and the communication method
that uses the message frame is called as the frame
communication.

｠

Basically, the communication data is used with
some blocks of 10-bit data group which includes
one start bit and one stop bit (byte region) arranged
in order.
