SIMPLIFIED WIRING SYSTEM (SWS)

54B-15

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.

REMINDER PREVENTING KEY FROM BEING LEFT IN IGNITION
If the driver's door is locked while it is open

If the driver's door is locked while it is open and when
the key is still in the ignition key cylinder, approxi-
mately 0.3 second later the ETACS-ECU activates
the unlock relay output for 0.25 second to prevent
the door from being locked with the key inside the
vehicle.

In addition, if locking the door was not prevented, a
re-try current is sent (an unlock relay output ON is
sent for 0.25 second up to 5 times including the first
attempt).
NOTE: The dotted line indicates that the system is
trying to turn on the unlock relay if the door cannot be
unlocked.

If the front passenger's door is open when it is locked with the driver's door switch

If the passenger's door or driver's door are locked
while the passenger's door is open and when the key
is still in the ignition key cylinder, approximately 0.3
seconds later the ETACS-ECU activates the unlock
relay output for 0.25 seconds to prevent the door
from being locked with the key inside the vehicle.

In addition, if locking the door was not prevented, a
re-try current is sent (an unlock relay output ON is
sent for 0.25 seconds up to 5 times including the first
attempt).
NOTE: The dotted line indicates that the system is
trying to turn on the unlock relay if the door cannot be
unlocked.

POWER WINDOW

Power window timer function
Even after the ignition is switched off, the ETACS-ECU keeps
the power window relay activated for approximately 30 sec-
onds, enabling raising or lowering of the power windows by
using the power window switches. After approximately 30 sec-
onds, the power window relay is deactivated.
During this timed operation, if the driver or passenger doors are
opened, the power window relay is deactivated from that
moment.

KEYLESS ENTRY SYSTEM

Keyless entry hazard answerback function*

If the keyless entry transmitter is used to send a lock signal to
the ETACS-ECU, all doors are locked and the hazard warning
lights flash once. If an unlock signal is sent, the driver's door is
unlocked first,*

and if a second signal is sent, all doors are

unlocked. Each time the unlock signal is sent, the hazard warn-
ing lights flash twice.
NOTE: *

: The hazard answerback function can be customized

using the keyless entry transmitter (Refer to Group 42

P.42-19

Keyless Entry System) or by using the multi center display
(middle grade type.) Refer to

P.54B-28

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-28

.).

Keyless entry horn answerback function
If the keyless entry transmitter is used to send a driver’s door
lock signal to the ETACS-ECU, the tone alarm sounds when
the ETACS-ECU receives the lock signal.
NOTE: : The horn answerback function can be customized by
using the keyless entry transmitter (Refer to Group 42

P.42-19

Keyless Entry System) or by using the multi center display
(middle grade type.) Refer to

P.54B-28

Trunk unlock function
Press the "TRUNK" button twice within 5 seconds and the trunk
lid will be unlocked.

Timed locking mechanism
After unlocking the doors with the keyless entry transmitter, if
no doors are opened, if the ignition key is not inserted or if the
locking function is not operated, the ETACS-ECU automatically
locks the doors in 30 seconds.
NOTE: The timed locking function can be customized on vehi-
cles equipped with a multi center display (middle grade type.)
Refer to

P.54B-28

SUNROOF

Sunroof timer function
The ETACS-ECU enables opening and closing of the sunroof
for 30 seconds after the ignition is switched off.
During this timed operation, if the driver's door or front passen-
ger’s door is opened, the sunroof timer function is deactivated
from that moment.

WINDSHIELD WIPER AND WASHER

Intermittent control (Vehicle speed-dependent variable
type)
ETACS-ECU uses the dial position of the variable intermittent
wiper control switch and the vehicle speed signal sent by the
combination meter to calculate the interval to be sent to the
front-ECU.
NOTE: The speed-sensitive wiper can be customized on vehi-
cles equipped with a multi center display (middle grade type.)
Refer to

P.54B-28

The front-ECU determines the intermittent time T1 from the
input SWS data signal, and turns ON the windshield wiper drive
signal. When the wiper is at the STOP position, the windshield
wiper auto-stop signal goes OFF then turn OFF the windshield
wiper drive signal. After the intermittent time T1 seconds from
when the windshield wiper drive signal turned ON, the wind-
shield wiper drive signal is turned ON again and the above
operation is repeated.
NOTE: If the intermittent time T1 is within 2 seconds, the wiper
is operated consecutively at LOW-speed by trhe front ECU.
