INTELLIGENT KEY SYSTEM
Revision: 2004 November 2004 FX35/FX45

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-115, "
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-115, "
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.
NOTE:
luggage room can enable detection of Intelligent Key by a CONSULT-II function. Refer to BL-115, "
WORK
SUPPORT" .

CHANGE SETTINGS FUNCTION
The settings for each function can be changed with the CONSULT-II or Intelligent Key operation.
Changing Settings With the Intelligent Key
Intelligent Key remote controller button and door request switch operations change the engine startup function
settings (startup enabled/disabled) for each Intelligent Key independently.
Settings Change Procedure
1. With the ignition switch is in the LOCK position (ignition knob not pressed), hold down both the LOCK and
UNLOCK remote control buttons on the Intelligent Key at the same time for at least 10 seconds (The yard-
stick is that the Intelligent Key LED flashes 20 times.)
2. Within 5 seconds of releasing the Intelligent Key remote controller buttons, press the driver door request
switch.
3. The KEY warning lamp in combination meter lights up for 3 seconds (engine starting enabled → starting
disabled: lights up red, engine starting disabled → flashes green). This completes the settings change.
Changing Settings Using CONSULT-II
The settings for the Intelligent Key system functions can be changed using CONSULT-II (WORK SUPPORT).
Refer to BL-115, "
WORK SUPPORT" .
NOTE:
Once a function setting is changed, it will remain effective even if the battery is disconnected.
Changing Settings Using Display Unit
The settings of the Intelligent Key system can be changed, using CONSULT-II, display unit, Intelligent Key and
door request switch in the center of the instrument panel. Refer to AV- 9 5 , "
Vehicle Electronic Systems" .
×: Applicable –: Not applicable
NOTE:
Once a function setting is changed, it will remain effective even if the battery is disconnected.
INTELLIGENT KEY REGISTRATION
Intelligent Key-ID registration is executed using the CONSULT-II. Up to 4 can be registered.
CAUTION:

After a new Intelligent Key-ID is registered, be sure to check the function.

When registering an additional Intelligent Key-ID, take any Intelligent Keys already registered and
Intelligent Keys for any other vehicles out of the vehicle before starting.
CONSULT-II can be used to check and delete Intelligent Key-IDs.
For future information, see the CONSULT-II Operation Manual NATS.
STEERING LOCK UNIT REGISTRATION
Steering Lock Unit ID Registration
CAUTION:

The method for registering a steering lock unit ID depends on the status of the steering lock unit
and Intelligent Key unit (new or old unit).

After registration is completed, press ignition knob with a portable unit in the vehicle so that it can
be rotated, and confirm that it cannot be rotated even when ignition switch is pressed without a
portable unit in the vehicle.
For further information, see the CONSULT-II Operation Manual NATS.
Setting item Description
Intelligent Key Lock Response-SoundThe sound pattern of the Intelligent Key operation can be set as desired. (Setting value:
OFF, Beeper or Horn chirp)

CAN Communication System DescriptionAIS004MX
CAN (Controller Area Network) is a serial communication line for real time application. It is an on-vehicle mul-
tiplex communication line with high data communication speed and excellent error detection ability. Many elec-
tronic control units are equipped onto a vehicle, and each control unit shares information and links with other
control units during operation (not independent). In CAN communication, control units are connected with 2
communication lines (CAN H line, CAN L line) allowing a high rate of information transmission with less wiring.
Each control unit transmits/receives data but selectively reads required data only.
CAN Communication UnitAIS004RN
Refer to LAN-6, "CAN COMMUNICATION" .
