TRUNK REQUEST SWITCH
TRUNK REQUEST SWITCH : System Diagram
TRUNK REQUEST SWITCH : System Description
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 carrying
the Intelligent 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 off to inform the driver (warning chime functions).
- When trunk is opened 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.
- 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.
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 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 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.
