TRUNK REQUEST SWITCH : System Description

INFOID:0000000004215628

Only when pressing the request switch, it is possible to open the trunk by carrying the Intelligent Key.

• The Intelligent Key system is a system that makes it possible to open the trunk (trunk open function) by car-

rying the Intelligent Key which operates based on the results of electronic ID verification using two-way com-

munications 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 off to inform the driver (warning chime functions).

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

Intelligent Key warning buzzer or horns sound (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. And then, check 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 consecutive

times.

• When BCM receives the trunk open request signal, it operates the trunk release solenoid and opens the

trunk.

OPERATION CONDITION

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.
