KOS-ECU
Controls KOS by using the following inputs/outputs and
communications.
• Input of front door lock/unlock switch, input of tailgate lock
release handle, and input of tailgate lock switch
• Communications with ETACS-ECU, OSS-ECU and
combination meter via CAN
• Wireless communication of keyless operation key via the
interior and exterior transmitter antennas as well as via the key
slot integrated antenna
• Output to the outer buzzer
• Output of actuator driving permission signal to electric steering
lock
Electric steering lock (incorporates
electric steering lock unit)
The steering lock mechanism incorporates a mechanism that can
electrically unlock the lock. When the lock is unlocked electrically,
the steering lock is unlocked approximately for 30 seconds by the
certification communication with OSS-ECU via LIN
communication, the power supply permission signal obtained via
wire communication, and the actuator driving permission signal
received via wire communication from KOS-ECU.

GENERAL INFORMATION
KEYLESS OPERATION SYSTEM (KOS)
42B-5
Keyless operation key (incorporates
emergency key)
• The keyless operation key receives signals sent from each
interior/exterior transmitter antenna, certifies the key ID code,
calculates the encrypted code, and sends the reply data signal
to KOS-ECU. If the integrated battery is discharged, the keyless
operation key receives signals sent from the key slot when it is
inserted in the key slot. Then, it certifies the key ID code,
calculates the encrypted code, and sends the reply data signal
to KOS-ECU via the key slot. Also, when the lock/unlock switch
on the keyless operation key is pressed, the corresponding
signal is sent to KOS-ECU.
• If two or more keyless operation keys registered in KOS-ECU
respond at the same time, their signals would interfere. To avoid
this interference, each signal from KOS-ECU is given the
priority
*
data, and the keyless operation keys respond in
accordance with this priority.
Lock/Unlock switch
Driver’s side
Locks/unlocks all the doors and tailgate when the driver carrying
the keyless operation key presses the lock/unlock switch on the
front door outside handle.
Passenger’s
side
Tailgate lock release handle
Unlocks all the doors and the tailgate when a driver carrying the
keyless operation key presses the tailgate lock release handle.
Tailgate lock switch
Locks all the doors and tailgate when the driver carrying the
keyless operation key presses the lock switch on the tailgate lock
release handle.
Exterior transmitter
antenna assembly
Driver’s side
Converts the data output from KOS-ECU via wire into a signal, and
sends it to the keyless operation key (For more information on the
transmission/reception area, refer to the door entry function valid
area
P.42B-8
).
Passenger’s
side
Tailgate
Interior transmitter
antenna assembly
Front
Converts the data output from KOS-ECU via wire into a signal, and
sends it to the keyless operation key (For more information on the
transmission/reception area, refer to the one-touch start system
valid area
P.42B-18
).
Rear
Outer buzzer
The outer buzzer sounds when:
• The doors are locked or unlocked by the door entry function.
• The keyless operation key is carried out of the vehicle when the
power supply mode is other than OFF, and the door is closed.
• The lock/unlock switch on the front door outside handle is
pressed when the power supply mode is other than OFF.
• The lock/unlock switch on the front door outside handle is
pressed when the keyless operation key is still located inside
the car.
• The lock/unlock switch on the front door outside handle is
pressed when the door is ajar.
• With the driver's door kept open, the keyless operation key is
not removed from the key slot located in the glove box.
Key slot
Converts the data output from KOS-ECU via wire into a signal,
sends it to the keyless operation key, and then sends the reply
data signal from keyless operation key to KOS-ECU.

GENERAL INFORMATION
KEYLESS OPERATION SYSTEM (KOS)
42B-6
NOTE:
*
: When registering the keyless operation
keys, KOS-ECU numbers each key (1 to 4) in the
order they are registered (initial priority). This priority
is renewed each time the doors are locked/unlocked
and the engine switch is pressed. For example, when
only keys 1 and 3 have responded to the signal sent
from KOS-ECU, the new priority of the keys would be
1-3-2-4. When keys 3 and 4 have responded, then
the priority of the keys becomes 3-4-1-2.
OSS-ECU
Controls OSS by using the following inputs/outputs and
communications.
• Input from the engine switch
• Input from stop lamp switch
• Input from P range detection switch
• Input of monitoring signal for actuator driving permission of
electric steering lock via wire communication with KOS-ECU
• Output of KOS back-up power supply via wire communication
with KOS-ECU
• Power supply output to electric steering lock unit
• CAN communication with KOS-ECU, ETACS-ECU, engine
ECU, and combination meter
• LIN communication with electric steering lock
Engine switch
• Output of engine switch ON/OFF signal to OSS-ECU
• Input of LED signal from OSS-ECU
Combination meter (keyless operation
alarm display)
Communicates with KOS-ECU and OSS-ECU via CAN. Receives
the warning request or warning information from KOS-ECU and
OSS-ECU, and displays the warning.
ETACS-ECU
• Communicates with KOS-ECU via CAN. By the door
lock/unlock request or tailgate lock/unlock request from
KOS-ECU, ETACS-ECU outputs the lock/unlock signal. When
the door lock/unlock signal is output, the ETACS-ECU flashes
or illuminates the turn-signal lamps and the room lamp to notify
the driver that the doors are locked/unlocked. Furthermore, by
the multi-mode function of keyless entry, the folding/unfolding of
door mirrors is performed depending on the pattern of door
lock/unlock request from KOS-ECU.
• Communicates with OSS-ECU via CAN, and outputs the door
switch ON/OFF signal.
• Receives the ACC output signal or IG1 output signal sent from
OSS-ECU via wire communication, and drives the ACC relay or
supplies electrical current to the IG1 relay to drive the IG1 relay.
• Using the welcome light function, the headlamps and tail lamps
are illuminated by the door unlock request from KOS-ECU.
Engine-ECU
Communicates with OSS-ECU through ETACS-ECU via CAN.
Permits/inhibits the engine starting and controls the engine
operation.
