INTELLIGENT KEY SYSTEM
 door switch OFF (when all the doors are closed);
Remote control button of Intelligent Key turns on interior lamp (for 30 seconds) with input of UNLOCK signal
from Intelligent Key.
Panic Alarm Function
When key switch is OFF and ignition knob is not pushed (when mechanical key is not inserted in ignition
knob), BCM turns ON and OFF horn and headlamp intermit tently with input of PANIC ALARM signal from
Intelligent Key. The alarm automatically turns off after 25 seconds or when Intelligent Key unit receives any
signal from Intelligent Key.
Panic alarm operation mode can be changed using “WORK SUPPORT” mode in “PANIC ALARM DELAY”.
Refer to BL-104, "
CONSULT-III Application Item".
Remote Control Power Window Down (Open) Operation
When Intelligent Key unlock switch is turned ON with i gnition switch OFF, and Intelligent Key unlock switch is
detected to be on continuously for 3 seconds, the driver's door and passenger's door power windows are
simultaneously opened.
Power window is operated to open and the operation continues as long as the Intelligent Key unlock switch is
pressed.
Remote control power window down operation mode can be changed using “P/W DOWN DELAY” mode in
“WORK SUPPORT”. Refer to BL-104, "
CONSULT-III Application Item".
Key Reminder Function
As an operation verification function, when doors are lock ed or unlocked using Intelligent Key remote control-
ler button operation, hazard lamps flash and horn sounds.
ENGINE STARTUP FUNCTION
Operation Description
 When ignition knob is pressed, Intelligent Key unit sends request signal from inside key antenna, key-ID ver- ification is conducted with Intelligent Key using two-wa y communication, and if verification is successful, an
ignition rotation prohibition latch release signal is sent to steering lock unit. Steering lock unit releases igni-
tion knob rotation prohibition latch. (Ignition knob can now be turned.)
 When it becomes possible to rotate the ignition knob, “KEY” warning lamp in combination meter lights up green to notify driver that ignition knob can be turned.
NOTE:
When it becomes impossible to rotate the ignition knob, “KEY” warning lamp in combination meter lights up
red.
 When key-ID verification is successful and ignition knob switch is in the ON state, Intelligent Key unit uses CAN communication to send engine start permission signal to BCM.
 When BCM receives engine start permission signal, it uses CAN communication to sent starter request sig-
nal to IPDM E/R so that the engine will start when ignition knob is rotated to START position.
Operation Range
Engine can be started when Intelligent Key is in the v ehicle. However, sometimes engine might not start when
Intelligent Key is on instrument panel, rear parcel shelf, or in glove box.
NOTE:
luggage room can enable detection of Intelligent Key by a CONSULT-III function. Refer to BL-104, "
CON-
SULT-III Application Item".
Active Check Function
Confirm whether or not ignition knob can be rotated by checking the color of warning lamp in combination
meter.
