< SYSTEM DESCRIPTION >

SYSTEM (INTELLIGENT KEY SYSTEM)

• The back door open function can open the back door by pressing the back door opener switch while carrying

the 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 antenna 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 system 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, back 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.
