GENERAL INFORMATION
M2541000100424
SWS is a minimal line system which transmits
numerous signals using one wiring.
To transmit numerous signals, the ETACS*1-ECU,
column switch (incorporating inside the col
-
umn-ECU) incorporate multi-distribution circuits to
carry out communication between control units.
ETACS-ECU can receive some input signals through
CAN
*2 communication, improving the SWS function.
NOTE: *1: ETACS (Electronic Time and Alarm Con-
trol System)
NOTE: *2: CAN (Controller Area Network)
For more information, refer to GROUP 54C P.54C-2.
