TRUNK REQUEST SWITCH : System Description

INFOID:0000000001683027

Only when pressing the request switch, it is possible to open the trunk by carrying the Intelligent Key.
• The Intelligent Key system makes it possible to open the trunk (trunk open function) by carrying the Intelli-

gent Key which operates based on the results of electronic ID verification using two-way communications
between the Intelligent Key and the vehicle. (BCM)

CAUTION:

The driver should always carry the Intelligent Key

• If an action that does not meet the operating conditions of the Intelligent Key system is taken, the buzzer

goes on to inform the driver. (Warning chime functions)

• When trunk opens with request switch or remote controller button operation, the hazard lamps flash and the

Intelligent Key warning buzzer or horn sounds (Hazard and buzzer/horn reminder function).

• The settings for each function can be changed with the 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 the CONSULT-III.

OPERATION DESCRIPTION/TRUNK OPEN

• When the BCM detects that trunk open request switch is pressed, it starts the outside key antenna (trunk

room) and inside key antenna corresponding to the pressed trunk open request switch and transmits the
request signal to the Intelligent Key. Then, it checks that the Intelligent Key is near the trunk.

• If the Intelligent Key is within the outside key antenna (trunk room) detection area, it receives the request sig-

nal 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 transmits the trunk open request signal and sounds Intelligent Key warning buzzer 4 times at the same

time.

• When BCM receives the trunk open request signal, it operates the trunk lid opener actuator and opens the

trunk.

TRUNK OPEN FUNCTION

If the following conditions are not satisfied, trunk open operation is not performed even if the request switch is
operated.

*: Even with a registered Intelligent Key remaining inside the vehicle, door locks can be unlocked from outside of the vehicle with a spare
Intelligent Key as long as key IDs are different.

OUTSIDE KEY ANTENNA DETECTION AREA

The outside key antenna detection area of trunk open function is in
the range of approximately 80 cm (31.50 in) surrounding trunk
opener request switch (1). However, this operating range depends
on the ambient conditions.

KEY REMINDER FUNCTION

*:If the door closing impact shocks the door lock knob, or contacts against baggage with the door lock knob might activate the door locks
accidentally but unlock operation will be perform at these cases.

CAUTION:

• The above function operates when the Intelligent Key is inside the vehicle. However, there may be

times when the Intelligent Key cannot be detected, and this function will not operate when the Intelli-
gent Key is on the instrument panel, rear parcel shelf, or in the glove box. Also, this system some-
times does not operate if the Intelligent Key is in the door pocket for the open door.

• When the key reminder function is operated when the trunk is opened/closed and the buzzers

sound, if the following operations are performed, the key reminder function is cleared and buzzer
sounds are stopped.

- Remote controller door lock button operation of Intelligent Key
- Remote controller door unlock button operation of Intelligent Key
- When the trunk is closed, the Intelligent Key is not inside the vehicle
- When any door is open

BUZZER REMINDER FUNCTION

During trunk opening operation by request switch, the Intelligent Key warning buzzer will honk as a reminder.
When trunk open by each request switch, IPDM E/R honks Intelligent Key warning buzzer as a reminder.
