GENERAL INFORMATION
COMMUNICATION LINE
Data lines for multiplex communication are connected between the front-ECU, ETACS-ECU, column switch

as illustrated below.

OPERATION
BUZZER
Light Reminder Warning Buzzer Function
When the driver’s door is opened with lighting switch
in the ON (tail lamp switch or headlamp switch)
position and ignition switch in the LOCK (OFF) or
ACC position, the buzzer will sound continuously to
remind the driver that the lamps (tail lamps or
headlamps) are ON.
This function does not work if the lighting switched
off through the headlamp automatic shutdownfunction. In addition, the ignition key reminder
warning buzzer function has a priority over this
function.
Center Display Operation Annunciation
Function
On vehicles with center display, the buzzer (peeps)
sounds when the operation switch of the audio
and navigation system is pressed.
CENTRAL DOOR LOCKING SYSTEM
Central Door Locking System Operation
When the lock switch is turned ON after the unlock
switch on the driver’s door lock actuator switch
is OFF, the ETACS-ECU gives a lock output for
0.5 second. When the unlock switch is turned ON
after the lock switch on the driver’s door lock
actuator switch is OFF, the ETACS-ECU gives an
unlock output for 0.5 second.
When the front passenger’s door key or back door
key is operated, the ETACS-ECU gives a lock or
unlock output for 0.5 second.Forgotten Key Prevention Function
If, with the key reminder switch OFF and the driver’s
door switch ON, the driver’s door lock switch is
turned ON after the door unlock switch in the front
door lock actuator is turned OFF, the ETACS-ECU
waits 0.3 second then give an unlock relay output
for 0.5 second, there by preventing the doors from
being locked. This operation prevents the ignition
key from being locked inside the vehicle. This
function takes precedence over the central door
locking control function.

SWS -General Information54B-3
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 signal (a SWS signal transmitted from
the ETACS-ECU) are turned ON [the power windowswitch 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.
If the driver’s door is opened during timer operation,
the receipt permission signal goes ON for additional
30 seconds. If the driver’s door is subsequently
closed during this period, the receipt permission
signal goes OFF ten seconds after the receipt
permission signal goes OFF.
KEYLESS ENTRY SYSTEM
Keyless Entry System Operation
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.
Keyless Entry Answerback Function
The keyless entry hazard answerable function
facilitates confirmation of door locking and unlock-
ing operations even in daylight. When a LOCKsignal from the keyless entry transmitter is applied
to the ETACS-ECU, all of the turn-signal lamps flash
twice. When an UNLOCK signal from the keyless
entry transmitter is applied to the ETACS-ECU, all of
the turn-signal lamps flash four times. Note that an
unlock switch has change from OFF to ON.
NOTE
The hazard answer back is enabled or disabled
by the configuration function.
SUNROOF
Sunroof Operation
All of the slide open/close, tilt up/down, and stop
operations can be performed by a single switch.
When the roof lid glass is tilted up, the sunshade
opens approximately 98 mm in combined operation
with the roof lid glass for better ventilation.
A jam preventing mechanism has been adopted.
When a slide-close or tilt-down operation is blocked
by an external force, the roof lid glass moves back
and stops.Sunroof Timer Function
When the ignition switch is turned from ON position
to LOCK (OFF) or ACC position, the sunroof will
be ready to work for 30 seconds.
If the driver’s door is opened during the timer
operation, the timer operates for another
30
seconds starting from that point. However, the
timer operation discontinues if the door is closed
during that period.
