GENERAL DESCRIPTION
SIMPLIFIED WIRING SYSTEM (SWS)54B-3
SEAT BELT TONE ALARM FUNCTION
If any of the following conditions is met with the igni-
tion switch at "ON" or "ST", the ETACS-ECU sounds
the tone alarm by using the driver's seat belt switch
signal and the vehicle speed signal sent from the
combination meter.
Sounds the tone alarm for six seconds when the
ignition switch is turned "ON" with the seat belt
switch on (the driver's seat belt is not fastened).
This is called "Timer function".
Sounds the tone alarm 12 cycles (after 0.5 sec-
onds) if any of the following conditions is met
when sixty seconds or more have elapsed since
the ignition switch is turned "ON". One cycle con-
sists of five-seconds "on" and then three-seconds
"off".
a. The vehicle speed has reached 8 km/h (5
mph) while the seat belt switch is turned on
(driver's seat belt is not fastened) with the
ignition switch "ON.
b. The seat belt switch has been turned on
(driver's seat belt has not been fastened) for
at least ten seconds while the ignition switch
has been turned "ON" and the vehicle speed
has been 8 km/h or more.
NOTE: Once the tone alarm has sounded 12
cycles, it does not sound again until the vehi-
cle speed reduces to 3 km/h (2 mph) or less
even if any of the following conditions is met.
The tone alarm stops sounding if the ignition
switch or the seat belt switch is turned off (the
driver's seat belt is fastened) while the timer
operation is active.
.
DOOR AJAR WARNING BUZZER
The buzzer is sounded 4 times by the ETACS-ECU
to warn the driver if any door is open when the igni-
tion is switched ON and the vehicle speed reaches 8
km/h or faster. The buzzer will continue to sound for
4 times even if the ignition, door status, or vehicle
speed requirements are not maintained.
.
MULTI CENTER DISPLAY OPERATION
TONE
The ETACS-ECU sounds the buzzer when the
buzzer signal is sent from the multi center display.
.
TURN-SIGNAL LAMP BUZZER
The ETACS-ECU sounds the buzzer in sync with the
turn-signal lamps or hazard warning lamps.
CENTRAL DOOR LOCKING SYSTEM
.
CENTRAL DOOR LOCKING SYSTEM
OPERATION
Door unlocking by operating the driver’s door lock
key cylinder:
When the ignition key is inserted in the driver’s
door lock key cylinder and turned clockwise to
unlock the driver’s door, the ETACS-ECU oper-
ates its door unlock relay and passes a current
through the door lock actuator of the driver’s door
for 0.25 seconds to unlock only the driver’s door.
When the ignition key is turned clockwise again,
the ETACS-ECU operates its door unlock relay
and passes a current through the door lock actu-
ators of all doors for 0.25 seconds and to unlock
all doors.
Door locking or unlocking by operating the driver’s or
front passenger’s door lock switch:
When the door is locked by the driver’s or front
passenger’s door lock switch, the ETACS-ECU
operates its door lock relay and passes a current
through the door lock actuators of all doors for
0.25 seconds to lock all doors.
When the door is unlocked by the driver’s or front
passenger's door lock switch, the ETACS-ECU
operates its door unlock relay and passes a cur-
rent through the door lock actuators of all doors
for 0.25 seconds to unlock all doors.
When the door is locked and unlocked by driver’s
or front passenger's door lock switch consecu-
tively, the ETACS-ECU operates its door lock
relay and passes a current through the door lock
actuators of all doors for 0.25 seconds to lock all
doors. Then, the ETACS-ECU operates its door
unlock relay and passes a current through the
door lock actuators of all doors for 0.25 seconds
to unlock all doors. Due to this, there may be a
time lag between the driver’s or front passenger's
door lock switch actuation and the time when all
doors are unlocked.

CENTRAL DOOR LOCKING SYSTEM
.
DOOR UNLOCKING BY OPERATING THE
DRIVER’S DOOR LOCK KEY CYLINDER
When the ignition key is inserted in the driver’s door lock key
cylinder and turned anti-clockwise to unlock the driver’s door,
the ETACS-ECU operates its door unlock relay and passes a
current through the door lock actuator of the driver’s door for
0.25 seconds to unlock only the driver’s door.
When the ignition key is turned anti-clockwise again, the
ETACS-ECU operates its door unlock relay and passes a cur-
rent through the door lock actuators of all doors for 0.25 sec-
onds and to unlock all doors.
NOTE: Vehicles with a multi center display (middle grade type)
can be customized so that a single unlock operation will unlock
all doors. Refer to P.54B-486.
.
DOOR LOCKING OR UNLOCKING BY
OPERATING THE DRIVER’S OR FRONT
PASSENGER’S DOOR LOCK SWITCH
When the door is locked by the driver’s or front passenger’s
door lock switch, the ETACS-ECU operates its door lock relay
and passes a current through the door lock actuators of all
doors for 0.25 seconds to lock all doors.
When the door is unlocked by the driver’s or front passenger's
door lock switch, the ETACS-ECU operates its door unlock
relay and passes a current through the door lock actuators of
all doors for 0.25 seconds to unlock all doors.
When the door is locked and unlocked by driver’s or front pas-
senger's door lock switch consecutively, the ETACS-ECU oper-
ates its door lock relay and passes a current through the door
lock actuators of all doors for 0.25 seconds to lock all doors.
Then, the ETACS-ECU operates its door unlock relay and
passes a current through the door lock actuators of all doors for
0.25 seconds to unlock all doors. Due to this, there may be a
time lag between the driver’s or front passenger's door lock
switch actuation and the time when all doors are unlocked.
