TRUNK OPEN FUNCTION : System DiagramINFOID:0000000003794746
TRUNK OPEN FUNCTION : System DescriptionINFOID:0000000003794747
TRUNK LID OPENER
 When the BCM detects that trunk lid opener request switch is pressed, it activates the outside key antenna
(rear bumper) and inside key antenna and transmits the request signal to the Intelligent Key. And then,
check that the Intelligent Key is near the trunk lid.
 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.
 BCM opens the trunk lid and sounds Intelligent Key warning buzzer and blinks hazard warning lamp at the
same time as a reminder.
TRUNK LID OPENER OPERATION
When trunk lid opener switch is ON, BCM opens trunk opener actuator.
BCM can open trunk lid opener actuator when
 vehicle speed is less than 5 km/h (3MPH)
 vehicle security system is disarmed or in the pre-armed phase
BCM does not open trunk lid opener actuator when
 vehicle speed is more than 5 km/h (3MPH)
 vehicle security system is armed or in the alarm phase
 Intelligent Key is inserted in key slot
OUTSIDE KEY ANTENNA DETECTION AREA
The outside key antenna detection area of trunk lid open function is
in the range of approximately 80 cm (31.50 in) surrounding the trunk
lid opener request switch (1). However, this operating range
depends on the ambient conditions.
HAZARD AND BUZZER REMINDER FUNCTION
When trunk lid opening operation is performed by trunk lid opener request switch, the hazard warning lamps
blink and Intelligent Key warning buzzer sounds as a reminder.
LIST OF OPERATION RELATED PARTS
The operation related parts are marked with ×.

REMOTE KEYLESS ENTRY FUNCTION : System DiagramINFOID:0000000003794750
REMOTE KEYLESS ENTRY FUNCTION : System DescriptionINFOID:0000000003794751
The Intelligent Key has the same functions as the remote control entry system. Therefore, it can be used in the
same manner as the remote controller by operating the door lock/unlock button.
OPERATION
Remote keyless entry system controls operation of the following items
 Door lock/unlock
 Trunk lid open
 Hazard and horn reminder
 Auto door lock
OPERATION AREA
To ensure the Intelligent Key works effectively, use within 1 m (3 ft) range of each door, however the operable
range may differ according to surroundings.
DOOR LOCK/UNLOCK FUNCTION
 When door lock/unlock button of the Intelligent Key is pressed, lock signal or unlock signal is transmitted
from Intelligent Key to BCM via remote keyless entry receiver.
 When BCM receives the door lock/unlock signal, it operates door lock actuator, blinks the hazard lamp (lock:
2 time, unlock: 1 times) and inputs horn chirp signal to IPDM E/R at the same time as a reminder.
 IPDM E/R honks horn (lock: 2 time) as a reminder
OPERATION CONDITION
TRUNK LID OPENER FUNCTION
When trunk lid button of Intelligent Key is pressed for more than 1 second, trunk lid open. For a detailed
description, refer to DLK-21, "
TRUNK OPEN FUNCTION : System Description".
HAZARD AND HORN REMINDER FUNCTION
When doors are locked or unlocked by Intelligent Key, BCM blinks hazard warning lamps as a reminder.
The hazard and horn reminder has a horn chirp mode (C mode) and a non-horn chirp mode (S mode).
