GENERAL INFORMATION

M15408500001USA0000010000

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.

Control System)
