tion using two-way communication between the Intelligent Key and the vehicle (BCM).
CAUTION:
The driver should always carry the Intelligent Key
 The settings for each function can be changed with CONSULT-III.
 If an Intelligent Key is lost, a new Intelligent Key can be registered. A maximum of 4 Intelligent Keys can be
registered.
 It is possible to perform a diagnosis on the system and register an Intelligent Key with CONSULT-III.

Only when pressing the door request switch, it is possi ble to lock and unlock the door by carrying the Intelli-
gent Key.
OPERATION DESCRIPTION
 When the BCM detects that each door request switch is pressed, it activates the outside key antenna and
inside key antenna corresponding to the pressed door reques t switch and transmits the request signal to the
Intelligent Key. And then, check that the Intelligent Key is near the door.
 If the Intelligent Key is within the outside key ant enna detection area, it receives the request signal and
transmits the key ID signal to the BCM via remote keyless entry receiver.
 BCM receives the key ID signal and compares it with the registered key ID.
 BCM locks/unlocks each doors (except back door).
 BCM sounds Intelligent Key warning buzzer (lock: 2 ti mes, unlock: 1 time) and blinks hazard warning lamps
(lock: 2 times, unlock: 1 time) at the same time as a reminder.

SYSTEM (INTELLIGENT KEY SYSTEM)
 The back door open function can open the back door by pressing the back door opener switch while carryingthe Intelligent Key and all doors (except back door) are locked.
 The back door open function enables the back door to be opened by pressing back door opener switch after
BCM transmits UNLOCK signal to each door.Refer to DLK-31, "
System Description".
BACK DOOR OPEN
While back door open in the permitted state, back door opens when back door opener switch is pressed after
back door request switch is operated. Back door open also can be operated according to the following proce-
dure.
 When the BCM detects that back door opener switch is pressed, it activates the outside key antenna (back
door) and inside key antenna and transmits the request signal to the Intelligent Key. And then, check that the
Intelligent Key is near the back door.
 If the Intelligent Key is within the outside key ant enna detection area, it receives the request signal and
transmits the key ID signal to the BCM via remote keyless entry receiver.
 BCM receives the key ID signal and compares it with the registered key ID.
 If the verification result is OK, BCM transmits the back door open request signal to automatic back door con- trol unit via CAN communication.
 Automatic back door control unit transmits back door open request signal to back door lock assembly and
back door is open.
 When the back door is open, automatic back door sys tem performs waiting operation for next back door
close operation.
The operation of then back door open is the same as the automatic back door system, refer to DLK-31,
"System Description".
OPERATION CONDITION
If the following conditions are not satisfied, ba ck door open operation is not performed even if the back door
opener switch is operated.
OUTSIDE KEY ANTENNA DETECTION AREA
The outside key antenna detection area of back door open function
is in the range of approximately 80 cm (31.50 in) surrounding the
outside key antenna (back door) (1). However, this operating range
depends on the ambient conditions.
LIST OF OPERATION RELATED PARTS
