DOOR ENTRY FUNCTION

Due to the abolishment of the unlock sensor for the 
door outside handle (driver's/passenger's side), the 
lock switch has been changed to a lock and unlock 
switch. The unlock/lock control has been changed. 
The other service procedures are the same as 
before.

.

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 on the driver-side/front passen-
ger-side door outside handle or the liftgate lock 
release handle is turned ON. When KOS-ECU certi-
fies the registered keyless operation key on the outer 
side of the vehicle, it requests ETACS-ECU to unlock 
the doors and the liftgate.

CONTROL OF UNLOCKING OPERATION

.

UNLOCKING OPERATION INHIBITION 
TIME (WHEN THE LIFTGATE IS 
OPERATED)

Considering that the customer operates the lock 
switch of liftgate 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 liftgate lock release 
handle.

.

LOCKING 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 on the driver-side/front passen-
ger-side door outside handle or the liftgate lock 
release handle (lock switch) is turned ON. When 
KOS-ECU certifies the registered keyless operation 
key only on the outer side of the vehicle, it requests 
ETACS-ECU to lock all the doors and the liftgate.
Dead lock function locks all the doors and liftgate, 
when the lock/unlock switch of door outside handle 
(driver's/passenger's side) is pressed once.
NOTE: When a keyless operation key is located 
inside the vehicle, KOS-ECU does not output a 
request for locking all the doors.
