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.

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.

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.
