POWER WINDOWS
Power Windows Operation
A signal line dedicated for transmission of multiplex
communication data is connected between the
power window main switches and the power window
motor-ECU.
Communication is uni-directional. The power
window main switches have a transmitting circuit
only, whereas the power window sub switches have
a receiving circuit only.
Power Window Timer Function
With the ignition switch in the ON position, the power
window relay and power window switch receipt
permission are turned ON [the power window switch
receipt permission signal remains ON for 30 seconds
after the ignition switch is turned LOCK (OFF)],
enabling opening and closing of the windows. The
power window relay goes ON for additional 30
seconds. If the driver's door is subsequently closed
during this period, the receipt permission signal goes
OFF. The power window relay goes OFF 10 seconds
after the receipt permission signal goes OFF.
KEYLESS ENTRY SYSTEM
If the transmitter LOCK or UNLOCK switch is
pressed while the ignition key is removed and all
of the doors are closed, the doors can be locked
or unlocked. If the doors are closed, the hazard
warning lamps, the room lamp and the horn will
operate due to answerback function. Because of
the answerback function, the hazard warning lamps flash twice, and the room lamp flashes twice when
the doors are locked. Meanwhile, when the doors
are unlocked, the hazard warning lamps flash and
the room lamp illuminate for 15 seconds. The hazard
answerback functions can be cancelled by using
the MUT-
II .
WINDSHIELD WIPER AND WASHER
Windshield Low-speed (and High-speed)
Wiper Operation
D
If the windshield low-speed wiper switch is
turned to the 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.
D
If the windshield high-speed wiper switch is
turned to the 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. (For vehicles without variable
intermittent wiper, the intermittent interval is fixed
at 4 seconds.) Then the ETACS-ECU sends a signal
to the front-ECU. The front-ECU determines the
wiper operation interval and turns on the wiper signal
relay. This causes 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
D
If the windshield mist wiper switch of the column
switch is turned to the 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.
D
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
turns on after the mist wiper switch is turned
off.
Windshield Washer Operation
If the windshield washer switch of the column switch
is turned to the 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 0.3 seconds.
After the windshield washer switch signal turns off,
the windshield wiper signal turns off in three
seconds.
If the windshield wiper switch is turned to the ON
position 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.
