SYSTEM OPERATION

KEYLESS OPERATION SYSTEM (KOS)

42B-9

When a driver carrying a keyless operation key
presses the lock/unlock switch on the front door out
side handle (driver's side, front passenger's side) or
the lock switch of tailgate lock release handle, the
KOS-ECU communicates with the keyless operation
key to authorise* the keyless operation key. When
the KOS-ECU senses the registered keyless opera-
tion key within 70 cm in radius from the periphery of
the vehicle, it requests the ETACS-ECU to
lock/unlock the doors (If the keyless operation key is
too high/low or too close to the vehicle, the door
entry function may not function).

NOTE: *: In the communication for certification of the
keyless operation key, KOS-ECU judges if the key-
less operation key ID (specified to keyless operation
key) contained in the response data from the keyless
operation key coincides with the ID that has been
stored in ECU by registration operation. The keyless
operation key sends the response to KOS-ECU only
when the KOS ID (specific to KOS-ECU) contained
in the received data coincided with the stored ID. In
the beginning of the communication for certification,
KOS-ECU creates an encrypted code calculation
factor in random number, and sends it to the keyless
operation key together with the transmit data. The
keyless operation key calculates the code by using

the received factor, and sends the result to
KOS-ECU together with the response data.
KOS-ECU determines that the communication is
established only when the code calculation results of
both parties coincided.

LOCKING OPERATION OF DOOR ENTRY
FUNCTION

The keyless operation key certification communica-
tion is performed when the lock/unlock switch of front
door outside handle (driver's side, front passenger's
side) or the lock switch of tailgate lock release han-
dle is turned ON. When KOS-ECU can certify the
registered keyless operation key outside the vehicle
only, it requests ETACS-ECU to lock all the doors
(including tailgate).

NOTE:

•

When a keyless operation key is located inside
the vehicle, KOS-ECU does not output a request
for locking all the doors.

•

When a keyless operation key with discharged
battery is inserted in the keyless operation key
slot, the keyless operation key is not certified to
be located inside the vehicle.

CONTROL OF LOCKING OPERATION

1. KOS-ECU detects the lock/unlock switch ON

signal of door outside handle (driver's side, front
passenger's side) or the lock switch ON signal of
tailgate lock release handle.

NOTE: When KOS-ECU detects the lock/unlock
switch ON signal of door outside handle (driver's
side, front passenger's side) or the lock switch ON
signal of tailgate lock release handle, KOS-ECU
judges the lock prohibition condition. When the
lock prohibition condition is met, the locking oper-
ation is terminated.

2. KOS-ECU transmits the exterior data from the

exterior transmitter antenna assembly on the
operation side.

3. After the exterior data are transmitted from the

exterior transmitter antenna assembly, the interior
data are transmitted from the interior transmitter
antenna assembly (front, rear).

4. After the specified time (varies with the number of

keyless operation keys registered in KOS-ECU)
has elapsed, a confirmation is made that there is
no keyless operation key located inside the
vehicle.

• When KOS-ECU receives the response from the

keyless operation key that received the interior
data, KOS-ECU terminates the process without
performing the locking operation.

5. KOS-ECU transmits the interior data from the

interior transmitter antenna assembly (front, rear).

6. After the specified time (varies with the number of

keyless operation keys registered in KOS-ECU)
has elapsed, a confirmation is made if the lock
conditions are met.

• When KOS-ECU receives the response from the

keyless operation key that received the interior
data, KOS-ECU terminates the process without
performing the locking operation.

• When all the responses from the registered key-

less operation key are the exterior data only,
KOS-ECU transmits the lock request to
ETACS-ECU. Also, KOS-ECU transmits the key-
less operation key number to ETACS-ECU.

NOTE: When multiple keyless operation keys

responded, KOS-ECU transmits ETACS-ECU the
key number of keyless operation key that
responded first. As for the transmission sequence
to ETACS-ECU, the keyless operation key
number is transmitted first, and then the lock
request is output.

• If there is no response from the keyless operation

key, Step 6 is performed once.

7. KOS-ECU transmits the exterior data from the

exterior transmitter antenna assembly on the
operation side.

8. If the specified time (varies with the number of

keyless operation keys registered in KOS-ECU)
has not elapsed, a confirmation is made if the lock
conditions are met.

• After retry, when the responses from the regis-

tered keyless operation key are the exterior data
only, KOS-ECU transmits the lock request
(request to lock the applicable position) to
ETACS-ECU. Also, KOS-ECU transmits the key-
less operation key number to ETACS-ECU.

NOTE: When multiple keyless operation keys

• When the locking operation is performed on the

driver's side, the priority order of keyless opera-
tion key is updated.

LOCKING OPERATION INHIBITION
CONDITIONS

In the following cases, the door locking operation is
inhibited.

• Any door or the tailgate is open (door switch is

ON). (including door ajar)

• Either of the exterior/interior transmitter antenna

assembly is being detected to be open, or it is
actually open.

• The wiring of exterior/interior transmitter antenna

assembly is contacting against the power supply
line.

• The engine switch is other than OFF.

• The lock and unlock signals are input at the same

time. (When the tailgate is operated)

• The door entry function is prohibited by the cus-

tomisation function.

UNLOCKING OPERATION OF DOOR
ENTRY FUNCTION

The keyless operation key and KOS-ECU communi-
cate to certify the keyless operation key when the
lock/unlock switch of front door outside handle
(driver’s side, front passenger's side) or the tailgate
lock release handle (open switch) is turned ON.
When KOS-ECU can certify the registered keyless
operation key outside the vehicle, it requests
ETACS-ECU to unlock all the doors (when a regis-
tered keyless operation key is certified outside the
vehicle, KOS-ECU requests ETACS-ECU to unlock
even when other registered keyless operation keys
are located inside the vehicle).

NOTE: When the driver's door limited unlocking
function is set to active using the customisation func-
tion, the operation can be performed using the
lock/unlock switch of front door outside handle
(driver's side). Within 2 seconds after the driver's
door is unlocked by pressing the lock/unlock switch
of front door outside handle (driver's side) once,
pressing the lock/unlock switch of front door outside
handle (driver's side) unlocks all the doors (including
tailgate).
