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.
