SWS is a minimal line system which transmits 
numerous signals using one wiring harness to 
reduce weight and complication of harnesses due to 
the increase in electronic accessories.
To transmit numerous signals, the ETACS*

-ECU, 

column switch (incorporating inside the col-
umn-ECU), front-ECU and sunroof-ECU incorporate 
multi-distribution circuits to carry out communication
