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.
