accepted, a door lock or door unlock request signal is sent to BCM via CAN communication to lock/unlock
the door.

When door lock/unlock is performed using Intelligent Key remote controller button operation, operation
confirmation is conducted by making hazard lamps flash and Intelligent Key warning buzzer sound.
OPERATION CONDITION
Door lock/unlock operation is necessary for all doors close.
Map Lamp And Keyhole Illumination Function
When the following conditions come:

condition of map lamp switch is DOOR position;

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 intermittently 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-120, "
WORK SUPPORT" .
Remote Control Power Window Down (Open) Operation
When Intelligent Key unlock switch is turned ON with ignition 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-120, "
WORK SUPPORT" .
Key Reminder Function
As an operation verification function, when doors are locked 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
verification is conducted with Intelligent Key using two-way communication, and if verification is success-
ful, an ignition rotation prohibition latch release signal is sent to steering lock unit. Steering lock unit
releases ignition 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
signal 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 vehicle. However, sometimes engine might not start when
Intelligent Key is on instrument panel, rear parcel shelf, or in glove box.
