REAR SUNROOF BUZZER FUNCTION

The ETACS-ECU triggers a warning buzzer when it
receives a buzzer request signal from the
sunroof-ECU. The buzzer keeps sounding for 1 full
second if the trigger conditions are eliminated while
the buzzer is ON.

CENTRAL DOOR LOCKING SYSTEM
CENTRAL DOOR LOCKING CONTROL
FUNCTION

When the front doors are locked (when the lock
switch turns ON after turning OFF the unlock switch
in the driver's door lock actuator), ETACS-ECU turns
ON the lock relay output for 0.25 second, and locks
all doors (including the tailgate).
When the front doors are unlocked (when the unlock
switch turns ON after turning OFF the lock switch on
the driver's door lock actuator), ETACS-ECU turns
ON the unlock relay output for 0.25 second, and
unlocks all doors (including the tailgate).

TAILGATE OPENER CONTROL
FUNCTION

When the tailgate lock release handle is pulled up
(tailgate lock release handle switch turns ON) while
the vehicle is parked and the tailgate is unlocked, the
ETACS-ECU turns ON the unlock relay output for 0.3
second, thus the tailgate can be opened by the
tailgate lock release handle.

KEYLESS ENTRY SYSTEM
MULTI-MODE KEYLESS ENTRY
FUNCTION

The power door mirrors can be operated by the
keyless entry transmitter operation.
NOTE: Availability of the door mirrors operation can
be adjusted with the customize function.

KEYLESS ENTRY HAZARD
ANSWER-BACK FUNCTION <INITIAL
SETTING: LOCK, FLASH ONCE,
UNLOCK, FLASH TWICE>

The hazard answerback function that allows
checking the lock/unlock state of the door easily
even in the daytime is installed. When the lock signal
from the keyless entry transmitter is received into
ETACS-ECU, all doors (including the tailgate) are
LOCK, and the turn signal lamp blinks once. When
the unlock signal is received, all doors (including the
tailgate) are UNLOCK, and the turn signal lamp
blinks twice.
NOTE: The answerback blink time can be adjusted
by the customize function.

ROOM LAMP ANSWER-BACK FUNCTION
<INITIAL SETTING: LOCK, FLASH ONCE,
UNLOCK, ILLUMINATES FOR 15
SECONDS>

When the ETACS-ECU receives the lock signal from
the keyless entry transmitter, all doors (including
tailgate) is locked and the interior lamp flashes once
in synchronization with the hazard lamp operation.
When the ETACS-ECU receives the unlock signal,
all doors (including tailgate) is unlocked. The interior
lamp fades in, keeps on, and fades out in 15 seconds
after the door unlock relay is operated. (15 seconds
including fading period)
NOTE: The answerback blink time can be adjusted
by the customize function.

TIMER LOCK FUNCTION <THE INITIAL
CONDITION: 30 SECONDS>

After unlocking the doors with the keyless entry
transmitter, if no doors are opened and 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 timer lock time can be adjusted by the
customize function.

POWER WINDOW
POWER WINDOW TIMER FUNCTION

When the power window relay and the power window
switch reception permit signal (SWS signals from
ETACS) are turned ON with the ignition switch ON
and the ignition switch is turned OFF, the power
window switch reception permit signal is kept ON for
approximately 30 seconds to enable the door
window operation by the power window switch. The
power window relay will be turned OFF 30 seconds
after terminating the reception permit signal.
If the driver's door is opened during the timer
operation, the reception permit signal is kept ON for
30 seconds from that time. However, when the
driver's door is closed, the reception permit signal is
turned OFF at the same time. The power window
relay will be turned OFF 30 seconds after terminating
the reception permit signal.

SUNROOF
Sunroof timer function

After turning OFF the ignition switch, the sunroof can
be operated by the sunroof switch for approximately
30 seconds.
When the driver's door is opened during the sunroof
timer operation, the sunroof timer operation will be
extended for sunroof timer operation time at that
time.

If the driver's door is closed during sunroof timer
operation, the sunroof operation is cancelled at the
same time.

WINDSHIELD WIPER AND WASHER
Intermittent control (Vehicle
speed-depended variable type) <the
initial condition: with function>

1.

The ETACS-ECU calculates the intermittent time

"T1" based on the position of the windshield
intermittent wiper control on the column switch
and the vehicle speed signal, which is transmitted
from the combination meter to the ETACS-ECU
through CAN communication, and constantly
transmits it to the front-ECU.

NOTE: Using a customize function, driver can enable

or disable the vehicle speed-sensitive function.
For more information about the customisation
feature.

2.

When the front-ECU receives the windshield

intermittent wiper switch ON signal from the
column switch while the ignition switch is in the
ACC or ON position, it turns the windshield wiper
relay on to operate the windshield wiper at low
speed.

3. When the windshield wiper comes to the stop

position, the windshield wiper auto stop signal
turns OFF. Then the windshield wiper relay will
turn OFF, and the windshield wiper stops
operating.

4. After the intermittent time (T1 second) sent from

the ETACS-ECU has elapsed after the windshield
wiper relay is turned ON, the windshield wiper
relay turns ON again, and the above procedure is
repeated.

NOTE: If the intermittent time "T1" is 2 seconds or
longer, the front-ECU operates the windshield wiper
at low speed.

MIST WIPER CONTROL

When the windshield wiper mist switch of the column
switch is turned ON while the ignition switch is ACC
or ON, the column switch turns ON the windshield
wiper drive signal. At the same time, the wiper speed
switch relay turns to ON (HI). When the windshield
mist wiper switch is ON, the windshield wiper
operates at the high speed. When the windshield
mist wiper switch is turned OFF while the windshield
wiper is operating in the mist mode, the windshield
wiper operates at low speed and then stops at the
auto stop position.
