INTELLIGENT KEY : System Description

INFOID:0000000005146880

The Intelligent Key has the same functions as the remote control entry system. In addition to other safety fea-

tures, it can be used to lock and unlock all doors as well as open the back door.

OPERATION DESCRIPTION/DOOR LOCK/UNLOCK FUNCTION

• When door lock/unlock button of the Intelligent Key is pressed, lock signal or unlock signal is transmitted

from Intelligent Key to BCM via remote keyless entry receiver and Intelligent Key unit.

• When BCM receives the door lock/unlock signal, it operates door lock actuator, flashes the hazard lamp

(lock: 2 times, unlock: 1 time) and horn chirp signal to IPDM E/R at the same time as a reminder.

• IPDM E/R honks horn (lock: 2 times) as a reminder

< FUNCTION DIAGNOSIS >

[WITH INTELLIGENT KEY SYSTEM]

DOOR LOCK FUNCTION

• To ensure the Intelligent Key works effectively, use within 80 cm range of each doors, however the operable

range may differ according to surroundings.

SELECTIVE UNLOCK FUNCTION

When a LOCK signal is transmitted from Intelligent Key, all doors will be locked.

When an UNLOCK signal is  transmitted from Intelligent Key once, driver's door will be unlocked.

Then, if an UNLOCK signal is transmitted from Intelligent Key again within 5 seconds, all other doors will be

unlocked.

When a liftgate signal is transmitted from Intelligent Key for more than 0.5 second, the back door operates to

the full open position. After opening, another signal will cause the back door to close.

HAZARD AND HORN REMINDER FUNCTION

When doors are locked or unlocked by Intelligent Key, BCM flashes hazard warning lamps as a reminder and

sends horn chirp signal to IPDM E/R. IPDM E/R sounds horn as a reminder.

The hazard and horn reminder has a horn chirp mode (C mode) and a non-horn chirp mode (S mode).

Operating function of hazard and horn reminder

Hazard and horn reminders do not operate if any door switch is ON (any door is OPEN).

How to change hazard and horn reminder mode

With CONSULT-III

Refer to 

DLK-55, "INTELLIGENT KEY : CONSULT-III Function (BCM - INTELLIGENT KEY)"

.

Without CONSULT-III

Refer to Owner's Manual for instructions.

AUTO DOOR LOCK FUNCTION

Auto Door Lock Function

When all doors are locked, ignition switch is OFF (ignition switch is not pressed) and key switch is OFF, doors

are unlocked with Intelligent Key button. When BCM does not receive the following signals within 30 seconds,

all doors are locked.

• Door switch is ON (door is opened)

• Door is locked

• Ignition switch is ON

• Key switch is ON (mechanical key is inserted in ignition key cylinder)

Auto door lock mode can be changed by DOOR LOCK-UNLOCK SET mode in “WORK SUPPORT”. Refer to

DLK-53, "DOOR LOCK : CONSULT-III Function (BCM - DOOR LOCK)"

.

PANIC ALARM FUNCTION

When ignition switch is OFF (ignition switch is not pressed) and key switch is OFF, BCM receives PANIC

ALARM signal from Intelligent Key through the remote keyless entry receiver and the Intelligent Key unit.

BCM turns on and off headlamp intermittently and  transmits theft warning horn signal to IPDM E/R. Then,

IPDM E/R turns on and off horn intermittently.

The headlamp flashes and the horn sounds intermittently.

The alarm automatically turns off:

• After 25 seconds

• When BCM receives any signal from Intelligent Key

Panic alarm function mode can be changed by PANIC ALARM SET mode in “WORK SUPPORT”. Refer to

DLK-55, "INTELLIGENT KEY : CONSULT-III Function (BCM - INTELLIGENT KEY)"

.

KEYLESS POWER WINDOW DOWN (OPEN) FUNCTION

Front power windows (with left and right front power window anti-pinch system) open when the unlock button

on Intelligent Key is activated and kept pressed for more than 3 seconds with the ignition switch OFF. The win-

dows keep opening if the unlock button is continuously pressed.

The power window opening stops when the following operations are performed:

• When the unlock button is kept pressed more than 15 seconds.

• When the ignition switch is turned ON while the power window opening is operated.

• When the unlock button is released.
