Parts name

Functional description

Keyless  operation  key  (incorporates
emergency key)

｠

The  keyless  operation  key  receives  signals  sent  from  each
interior/exterior  transmitter  antenna,  certifies  the  keyless
operation  key  ID  code,  calculates  the  encrypted  code,  and
sends  the  reply  data  signal  to  KOS-ECU  via  the  receiver
antenna module. When the lock/unlock switch on the keyless
operation key is pressed, corresponding signal is sent to KOS-
ECU via the receiver antenna module.

｠

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*1data, and the keyless operation keys respond in
accordance with this priority.

Lock switch

Driver's door

Locks all the doors and the liftgate when a driver carrying the
keyless operation key presses the lock switch on the front door
outside handle or on the liftgate lock release handle.

Unlock sensor

Driver's door

The  unlock  sensors  incorporated  in  the  driver’s  front  door
outside handles unlock driver’s the door when a driver carrying
the keyless operation key pulls the driver’s door outside handle.

Front

 passenger's

door

The unlock sensors incorporated in the passenger's front door
outside  handles  unlock  all  the  doors  and  the  liftgate  when  a
driver  carrying  the  keyless  operation  key  pulls  the  front  door
outside handle.

Liftgate lock release handle

Locks all the doors and the liftgate when a driver carrying the

｠

The doors are locked or unlocked by the door entry function.

｠

The keyless operation key is brought out of the vehicle when
the  IG  knob  is  in  the  "LOCK"  (OFF)  position  and  the  push
switch is in other than the ON position.

｠

The  lock  switch  on  the  keyless  operation  switch  is  pressed
when the IG knob is in the "LOCK" (OFF) position and the push
switch is in other than the ON position.

｠

The lock switch on the keyless operation key is pressed from
inside the car.

｠

The lock switch on the keyless operation key is pressed when
the door is ajar.

KEYLESS OPERATION SYSTEM (KOS)

42B-7

GENERAL INFORMATION

Parts name

Functional description

Receiver antenna module

Receives  the  operation  signals  from  the  lock/unlock  switches
and panic alarm switch on the keyless operation key, and the air
pressure signal from the TPMS transmitter, and then converts
them into data and sends them to KOS-ECU.

TPMS transmitter

Measure tire pressure directly, then send radio frequency signal
to receiver antenna module.

Combination  meter  (Multi  information
display, TPMS warning light)

Communicates with KOS-ECU via CAN. Receives the warning
request  or  warning  information  from  KOS-ECU,  flashes  or
activates*2the warning indicator or warnig light. Warning symbol
and message is additionally displayed on the multi information
display

ETACS-ECU

Communicates  with  KOS-ECU  via  CAN.  Send  ignition  switch
status. Receives the door lock/unlock request from KOS-ECU,
outputs the lock/unlock signal, and flashes the turn signal light
to inform the driver that the doors are locked/unlocked.

ECM

Communicates  with  KOS-ECU  via  CAN.  Permits/inhibits  the
engine  starting  and  controls  the  engine  operation.  Send
atmospheric pressure data.

ABS or ASC-ECU

Communicates  with  KOS-ECU  via  CAN.  Sends  the  vehicle
speed data.

NOTE: 

 *1: 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 IG knob 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.

NOTE: 

 *2: Illuminates for tire pressure warning.

Flashes for about 1 minute and then coutinuously
illuminated for TPMS malfunction warning.
