GENERAL INFORMATION

SMART WIRING SYSTEM (SWS) NOT USING SWS MONITOR

54B-8

When the ignition switch is turned ON with the
driver’s seat belt unbuckled, the ETACS-ECU
triggers a warning buzzer (repetition of a short beep
sound) for 6 seconds to notify the driver that the seat
belt is not fastened.
When the ETACS-ECU detects that the vehicle
speed signal sent from the combination meter
through CAN communication exceeds 8 km/h and
the driver’s seat belt buckle is not engaged, it will
trigger a warning buzzer (repetition of 5-second ON
and 2.8-second OFF for 12 cycles). The
ETACS-ECU stops the buzzer when the driver’s seat
belt buckle is engaged while the warning cycle is ON.

DOOR AJAR WARNING BUZZER
FUNCTION <THE INITIAL CONDITION:
WITH FUNCTION>

If the vehicle speed exceeds 8 km/h with the
door-ajar, the buzzer sounds (pings eight times) to
alert the driver that the door is not properly closed.
NOTE: Availability of the door-ajar alarm function
can be selected by the customize function.

Turn-signal lamp buzzer function <the
initial condition: Without function>

ETACS-ECU buzzer sounds simultaneously with the
blinks of the turn signal lamp and the hazard lamp.
