SYSTEM OPERATION

KEYLESS OPERATION SYSTEM (KOS)

42B-12

CONTROL OF UNLOCKING OPERATION

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

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

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

2. When KOS-ECU detects the lock/unlock switch 

ON signal of front door outside handle (driver's 
side, front passenger's side) or the tailgate lock 
release handle (open switch) ON signal, 
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. For the specified time (varies with the number of 

keyless operation keys registered in KOS-ECU), 

the response from the keyless operation key 
meeting the unlock condition is monitored.

SYSTEM OPERATION

KEYLESS OPERATION SYSTEM (KOS)

42B-13

• When the registered keyless operation key 

receives the exterior data only, KOS-ECU trans-
mits the unlock request (request to unlock the 
applicable position) to ETACS-ECU.

• Even after the specified time has elapsed, if 

KOS-ECU receives no response that satisfies the 
unlock, it performs a retry once. (When no 
response after the retry, KOS-ECU terminates 
the unlocking operation.)

• When the unlocking operation is performed on 

the driver's side, the priority order of keyless 
operation key is updated.

UNLOCKING OPERATION INHIBITION 
TIME (WHEN THE TAILGATE IS 
OPERATED)

Considering that the customer operates the lock 
switch of tailgate lock release handle to make sure 
the doors are locked, the unlocking operation is pro-
hibited for 3 seconds after the locking operation is 
performed by the lock switch of tailgate lock release 
handle. Using the customisation function, the unlock 
prohibition time can be changed.

UNLOCKING OPERATION INHIBITION 
CONDITIONS

In the following cases, the unlocking operation is pro-
hibited.

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

ON). (including door ajar)

• Inside lock knob position of driver's side and front 

passenger's side is set to Unlock.

• The engine switch is other than OFF.

• The lock and unlock signals are input at the same 

time. (When the tailgate is operated)

• The exterior/interior transmitter antenna assem-

bly is being detected to be open, or it is open.

• The wiring of exterior/interior transmitter antenna 

assembly is contacting against the power supply 
line.

• During the unlocking operation inhibition time 

(When the tailgate is operated)

• The door entry function is prohibited by the cus-

tomisation function.

ANSWERBACK FUNCTIONS

When KOS-ECU sends a signal to ETACS-ECU, 
ETACS-ECU outputs the lock/unlock signal and acti-
vates the hazard warning lamp to notify the driver the 
doors are locked/unlocked.

KOS TIMER LOCK FUNCTION

When none of the doors are opened within 30 sec-
onds after the doors are unlocked by KOS, 
ETACS-ECU automatically outputs the door lock sig-
nal to lock the doors. This function prevents the 
doors from being unlocked accidentally.

KEYLESS ENTRY FUNCTION

M2421000400512

This keyless entry function has the following fea-
tures:

• A two switches keyless operation key with lock 

and unlock switches is adopted <Vehicles without 
electric tailgate>.

• A three switches keyless operation key with lock, 

unlock and electric tailgate switches is adopted

NOTE: The answerback function can be enabled/dis-

abled using a customisation function (Refer to 

P.42B-31

).

• Using the lock/unlock switches, all doors (includ-

ing tailgate) can be locked or unlocked, door mir-
rors can be retracted or opened <Vehicles with 
electric-folding door mirrors>.

NOTE: Using the customisation function, a change 

for multi-mode function (door mirrors) can be set. 
(Refer to 

P.42B-31

.)

• Keyless entry timer lock

NOTE: Timer of the keyless entry timer lock can be 

enabled/disabled using a customisation function 
(Refer to

DESCRIPTION OF CONSTRUCTION AND 
OPERATION

KEYLESS OPERATION KEY

• The two switches <vehicles without electric tail-

gate> and three switches <vehicles with electric 
tailgate> have been adopted for keyless opera-
tion key, and the specific encrypted code is trans-
mitted as radio wave signal.

• A shining three-diamond mark on the back of the 

keyless operation key gives it a classy look.

• Matt-plating is adopted for switches to improve 

appearance.

• An indicator lamp, which illuminates when signals 

are received, is added on the keyless operation 
key. This indicator lamp informs you of the signal 
transmission status and warns you of flat battery.

• The switch operation of the keyless operation key 

allows the system to operate as follows:
