GENERAL DESCRIPTION
TSB Revision
SIMPLIFIED WIRING SYSTEM (SWS)
54B-3
POWER WINDOW RELAY CONTROL
Power Window Relay Operation
If the ignition switch is turned to "ON" position, the
power window relay is energized to activate the
power windows.
Power Window Timer Function
When the ignition switch is turned from "ON" position
to "LOCK" (OFF) or "ACC" position, the power
windows will be ready to work for 30 seconds, the
power windows will be immobilized at that point.
KEYLESS ENTRY SYSTEM
Keyless Entry Answerback Function
If the transmitter "LOCK" or "UNLOCK" switch is
pressed while the ignition key is removed, the doors
can be locked or unlocked. If the doors are closed,
the hazard warning lights, the dome light and the
horn will operate due to answerback function.
Because of the answerback function, the hazard
warning lights flash twice, and the horn sounds once,
the dome light flashes twice when the doors are
locked. Meanwhile, when the doors are unlocked,
the hazard warning lights flash and the dome light
illuminates for 30 seconds. The hazard and the horn
answerback functions can be cancelled by using the
transmitter.
WINDSHIELD WIPERS AND WASHERS
Windshield Low-speed (and High-speed) Wiper
Operation
•
If the windshield low-speed wiper switch is turned
to ON position with the ignition switch at the
"ACC" or "ON" position, the column switch sends
a low-speed wiper ON and high-speed wiper OFF
signals to the front-ECU. This turns the wiper
signal on and the wiper speed switching relay off
(low-speed), causing the wipers to operate at
low-speed.
•
If the windshield high-speed wiper switch is
turned to ON position, the column switch sends a
low-speed wiper OFF and high-speed wiper ON
signals to the front-ECU. This turns both the
wiper signal and the wiper speed switching relay
on (high-speed), causing the wipers to operate at
high-speed.
Windshield Intermittent Wiper Operation
The ETACS-ECU calculates the wiper operation
interval according to the voltage signal sent from the
column switch. Then the ETACS-ECU sends a signal
to the front-ECU. The front-ECU determines the
wiper operation interval and turns on the wiper relay
signal relay. This causes the wiper auto stop relay to
turn on. Then the wiper auto stop relay to turn on.
Then the wiper auto stop relay will turn off after the
wipers reach the park position. This causes the wiper
signal relay and then the wipers to turn off. If the
wiper signal relay remains off for the wiper operation
interval, the relay turns on again, causing the wipers
to operate in intermittent mode.
Windshield Mist Wiper Operation
•
If the windshield mist wiper switch is turned to ON
position with the ignition switch at "ACC" or "ON"
position, the mist wiper high-speed operation
signal is sent to the front-ECU. This signal turns
on the wiper speed switching relay, causing the
wipers to work at high-speed while the mist
switch is on.
•
While the windshield mist wiper switch remains
turned on when the intermittent mode is still
working, the wipers work as the mist wiper.
However, the wipers return to the intermittent
mode again when the wiper auto stop signal turn
on after the windshield mist wiper switch is turned
off.
Windshield Washer Operation
•
If the windshield washer switch is turned to ON
position with the ignition switch at "ACC" or "ON"
position, the windshield washer ON signal is sent
to the front-ECU, causing the windshield wiper
signal to turn on after 0.6 seconds. After the
windshield washer switch signal turns off, the
windshield wiper signal turns off in three seconds.
•
If the windshield washer switch is turned on while
the windshield wiper is at intermittent mode, the
windshield washer works for that period when the
windshield washer switch remains on. Then the
wipers return to the intermittent mode.
SEAT BELT WARNING LIGHT
If the driver turns the ignition switch to the "ON"
position without wearing the seat belt, the seat belt
warning light illuminates to alert the driver to wear
the seat belt.
IGNITION KEY HOLE ILLUMINATION
LIGHT
When the ignition switch is turned to "LOCK" (OFF)
or "ACC" position with the driver's door opened, the
ignition key hole illumination light is illuminated. If the
door is closed in that state, the light goes out after 30
seconds or it illuminates for 30 seconds after the
ignition key is removed. In either case the light goes
out when the ignition switch is turned to the "ON"
position.
