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.

GENERAL DESCRIPTION
SIMPLIFIED WIRING SYSTEM (SWS)54B-4
.
FORGOTTEN KEY PREVENTION
FUNCTION
If the driver's door is locked while it is open and
when the key is still in the ignition key cylinder,
approximately 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 sec-
ond up to 5 times including the first attempt).
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, approxi-
mately 0.3 second later the ETACS-ECU acti-
vates 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).
POWER WINDOW RELAY CONTROL
.
POWER WINDOW RELAY OPERATION
If the ignition switch is turned to "ON" or "ACC" posi-
tion, the power window relay is energized to activate
the power windows.
.
POWER WINDOW TIMER FUNCTION
Even after the ignition is switched off, the
ETACS-ECU keeps the power window relay acti-
vated for approximately 30 seconds, enabling raising
and 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 ANSWER-
BACK FUNCTION
If the keyless entry transmitter is used to send a lock
signal to the ETACS-ECU, all doors, the liftgate, and
the glass hatch are locked and the hazard warning
lamps flash once. If an unlock signal is sent, the
driver's door is unlocked first, and if a second signal
is sent, all doors, the liftgate, and the glass hatch are
unlocked. Each time the unlock signal is sent, the
hazard warning lamps flash twice.
.
KEYLESS ENTRY HORN ANSWERBACK
FUNCTION
If the keyless entry transmitter is used to send 2 lock
signals to the ETACS-ECU, the first signal locks all
doors, while the second signal sounds the horn once.
.
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 or if the ignition
key is not inserted, the ETACS-ECU automatically
locks the doors in 30 seconds.
SUNROOF CONTROL
.
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 or front
passenger’s door is opened, the sunroof timer func-
tion is deactivated from that moment.
WINDSHIELD WIPERS AND WASHERS
.
LOW SPEED WIPER, HIGH SPEED WIPER
CONTROL
When the ignition switch in at the ACC or ON
position, and the windshield low speed wiper
switch of the column switch is turned ON, the
front-ECU turns ON the windshield wiper drive
signal, turns OFF (LO) the windshield wiper
speed relay, and operates the windshield wiper at
low speed.
When the windshield high speed wiper switch is
turned ON, the windshield wiper drive signal is
turned ON, the windshield wiper speed switching
relay is turned ON (HI), and the windshield wiper
is operated at high speed.
.

GENERAL DESCRIPTION
SIMPLIFIED WIRING SYSTEM (SWS)54B-5
INTERMITTENT CONTROL
ETACS-ECU uses the dial position of the variable
intermittent wiper control switch and the vehicle
speed signal sent by the combination meter to calcu-
late the interval to be sent to the front-ECU. The
front-ECU determines the intermittent time 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 to turn OFF the windshield wiper drive signal.
After the intermittent time from when the windshield
wiper drive signal turned ON, the windshield wiper
drive signal is turned ON again and the above opera-
tion is repeated.
.
MIST WIPER CONTROL
When the ignition switch is in the ACC or ON posi-
tion, and the windshield mist wiper switch of the col-
umn switch is turned ON, the front-ECU turns ON the
windshield wiper drive signal. At the same time, the
wiper speed switching relay is turned ON
(HIGH-SPEED). While the windshield mist wiper
switch is ON, the windshield wiper will operate at
high speed. Then, if the windshield mist wiper switch
is turned off, the wiper operates at low speed until it
stops at the predetermined park position.
When the windshield mist switch is turned on briefly,
the wiper operates once at low speed.
At the point the windshield mist switch is turned ON,
if the windshield wiper has been operating intermit-
tently, the same operations as the above will be per-
formed while the windshield mist wiper switch is ON.
After the windshield mist wiper switch goes OFF, the
intermittent operations will be set again after the
windshield wiper auto-stop signal last is turned ON.
.
WASHER CONTROL
When the ignition switch is in the ACC or ON posi-
tion, and the windshield washer switch of the column
switch is turned ON, the front-ECU turns ON the
windshield washer relay. The windshield wiper drive
signal is turned ON in 0.15 seconds until 2 seconds
after the windshield washer switch goes OFF to
operate the windshield wiper continuously. When the
windshield washer switch is turned ON, if the wind-
shield wiper is operating intermittently, intermittent
operations will be continued after continuous opera-
tions.
HEADLAMP
.
HEADLAMP AUTOMATIC SHUTDOWN
FUNCTION
Even if the lighting switch (tail lamp switch or
headlamp switch) is ON, the headlamps and tail
lamps will automatically go off in the following condi-
tions to prevent the battery from discharging:
When the ignition key is turned from "ON" to "LOCK"
(OFF) or "ACC" position with the lighting switch
turned ON, and this state continues for three min-
utes, the lamp will automatically be turned off. If the
driver's seat door is opened during these three min-
utes, the lamp will go off one second later.
.
HIGH-BEAM INDICATOR
At the same time that the high beams are illumi-
nated, the ETACS-ECU sends a signal to illuminate
the high-beam indicator via the CAN bus line. The
combination meter receives the transmitted signal
and turns the high-beam indicator on and off.
FLASHER TIMER
.
TURN-SIGNAL LAMP
The turn-signal lamp output (flashing signal) is
turned ON when the ignition switch is ON and the
turn-signal lamp switch is ON (LH or RH). If the front
turn-signal lamp or rear turn-signal lamp bulb has
burned out, the flashing speed increases to indicate
that the bulb has burned out.
.
HAZARD WARNING LAMP
Detects the signal where the hazard warning lamp
switch input changes from OFF to ON, and reverse
the flashing state according to this signal. The haz-
ard warning lamps toggle on and off whenever the
hazard warning lamp switch is operated.
.
TURN-SIGNAL INDICATORS
At the same time that the turn-signal lamps are illu-
minated, the ETACS-ECU sends a signal to illumi-
nate the turn-signal lamp indicator via the CAN bus
line. The combination meter receives the transmitted
signal and turns the turn-signal lamp indicator on and
off.

GENERAL DESCRIPTION
SIMPLIFIED WIRING SYSTEM (SWS)54B-6
FOG LAMP
.
FOG LAMP
The fog lamps will illuminate only when the fog lamp
switch is operated while the low-beam headlamps
are on.
The fog lamps will be switched off when any of the
following conditions is met. The fog lamps will also
be switched off automatically by headlamp automatic
shutdown function.
When the high-beam headlamps are switched
on, the fog lamps will be switched off. If the
low-beam headlamps are switched on again, the
fog lamps will illuminate again.
When the headlamp switch is turned off while the
tail lamps are on or the tail lamps and headlamps
are off, the fog lamps will be switched off. If the
low-beam headlamps are switched on again, the
fog lamps will not illuminate again.
.
FOG LAMP INDICATOR
At the same time that the fog lamps are illuminated,
the ETACS-ECU sends a signal to illuminate the fog
lamp indicator via the CAN bus line. The combination
meter receives the transmitted signal and turns the
fog lamp indicator on and off.
INTERIOR LAMP
ETACS-ECU makes it possible to force operation of
all ON and OFF lamp switches in the overhead con-
sole (the dome lamp, reading lamp, cargo area lamp,
rear personal lamps, front door lamps, and front foot
lamps). This function is assigned higher priority than
the controls for the interior lamp switch that are per-
formed when the doors are in certain positions.
When the lamps are forced on, the illumination
level is 100% as all interior lamps are switched on
(the dome lamp, reading lamp, cargo area lamp,
rear personal lamps, front door lamps, and front
foot lamps). Even when all lamps are forced on,
the interior lamp automatic shutoff function is
active.
When the lamps are forced off, all interior lamps
are immediately switched off (the dome lamp,
reading lamp, cargo area lamp, rear personal
lamps, front door lamps, and front foot lamps).When the interior lamp switch is at DOOR position,
the ETACS-ECU controls the interior lamps as fol-
lows:
When a door is opened with the ignition switch
off, the interior lamps up to a luminance of 100
percent. When a door is closed, the interior lamps
dims a luminance of 65 percent, and goes off 30
seconds later. However, if the ignition switch is
turned ON or if a door is locked while the interior
lamps is dimming, the dome lamp will go off at
that point.
When a door is opened with the ignition switch
ON, the interior lamps up at a luminance of 100
percent. When all doors are closed, the interior
lamps go off.
When the ignition key is removed with all doors
closed, the interior lamps up at a luminance of
100 percent, and goes off 30 seconds later. How-
ever, if the ignition key is inserted again or if a
door is locked while the interior lamps is lighting,
the interior lamps will go off at that point.
To check keyless entry operations more easily,
the interior lamps will flash twice when doors are
locked. When doors are unlocked, the interior
lamps up at a luminance of 100 percent, and
goes off 15 seconds later.
INTERIOR LAMP AUTOMATIC
SHUTDOUN FUNCTION
Illuminated interior lamps such as the front dome
lamp, etc. (all lamps using the dome lamp fuse as the
power supply) will automatically go off in the follow-
ing conditions to prevent the battery from discharging
as a result of forgetting to turn off the lamps or
incomplete closing of the door.
When the ignition switch is turned off and more
than 30 minutes pass by with the interior lamp
illuminated, the interior lamps will go off automati-
cally.
When the ignition switch is turned off and one of
the door switches remains open for 30 minutes
continuously, the interior lamps will go off auto-
matically.

GENERAL DESCRIPTION
SIMPLIFIED WIRING SYSTEM (SWS)54B-7
SEAT BELT INDICATOR
If any of the following conditions is met with the igni-
tion switch at "ON" or "ST", the ETACS-ECU illumi-
nates, flashes or extinguishes the seat belt indicator
by using the driver's seat belt switch signal and the
vehicle speed signal sent from the combination
meter.
Illuminates when the ignition switch is at "ON"
and the seat belt switch is turned on (the driver's
seat belt is unfastened).
Flashes and illuminates the indicator 12 cycles
(after 0.5 seconds) if any of the following condi-
tions is met when sixty seconds or more have
elapsed since the ignition switch is turned "ON".
One cycle consists of five-second "flashing" and
then three-second "illumination".
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 (5 mph) or more.
NOTE: Once this timer operation has been acti-
vated, it will not be activated again until the
vehicle speed reduces to 3 km/h (2 mph) or
less even if any of the following conditions is
met.
The indicator stops illuminating 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 INDICATOR LAMP
The combination meter receives the signal sent from
the ETACS-ECU about whether each door or trunk is
open or closed and turns the door ajar indicator lamp
on and off. While the door ajar indicator is illumi-
nated, the door ajar warning function is activated and
the door ajar indicator lamp flashes 4 times. If the
door remains open even after the 4 warning flashes,
the door ajar indicator lamp will be illuminated again.
