NOTE: Availability of the turn signal lamp operation 
tone function can be selected by the customize 
function.

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.
