REMOTE KEYLESS ENTRY FUNCTIONS
The Intelligent Key has the same functions as the remote control entry system. Therefore, it can be used in the
same manner as the remote controller by operating the door lock/unlock button and trunk open button.
System Diagram
Operation Description/Door Lock/Unlock Function

When door lock/unlock button of the Intelligent Key is pressed, lock signal or unlock signal is sent from
Intelligent Key to Intelligent Key unit via remote keyless entry receiver.

Intelligent Key unit sends the door lock/unlock request signal to BCM via CAN communication line.

Intelligent Key unit sends the door lock/unlock signal to BCM.

When BCM receives the door lock/unlock signal, it operates door lock actuator, flashes the hazard lamp
(lock: 1 time, unlock: 2 times) and horn chirp signal to IPDM E/R at the same time as a reminder.

IPDM E/R honks horn (lock: 1 time) as a reminder
Operation Description/Trunk Open Function

When trunk button of the Intelligent Key is pressed, the trunk open signal is sent from the Intelligent Key to
the Intelligent Key unit via remote keyless entry receiver.

Intelligent Key unit sends trunk open request signal to BCM via CAN communication line.

When BCM receives the trunk open request signal, it operates the trunk lid opener actuator and opens the
trunk.
Operation Condition
Operation Area

Operating Range

To ensure the Intelligent Key works effectively, use within 100 cm range of each doors, however the oper-
able range might be differ by surroundings.
Selective Unlock Function
When an LOCK signal is sent from Intelligent Key, all doors will be locked.
When an UNLOCK signal is sent from Intelligent Key once, driver's door will be unlocked.
Then, if an UNLOCK signal is sent from Intelligent Key again within 5 seconds, all other door will be unlocked.

Hazard and Horn Reminder Function
When doors are locked or unlocked by Intelligent Key, Intelligent Key unit sends hazard and horn request sig-
nal to BCM via CAN communication line.
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 reminder does not operate if any door switch is ON (any door is OPEN).
How to change hazard and horn reminder mode
With CONSULT-II
Hazard and horn reminder can be changed using “HORN WITH KEYLESS LOCK” and “HAZARD ANSWER
BACK” mode in “WORK SUPPORT”.Refer to BL-81, "
WORK SUPPORT" .
Without CONSULT-II
When LOCK and UNLOCK signals are sent from the Intelligent Key for more than 2 seconds at the same time,
the hazard and horn reminder mode is changed and hazard warning lamp flashes and horn sounds as follows:
Auto Door Lock Function
When all doors are locked, ignition switch is OFF (ignition switch is not pressed) and key switch is OFF (Intel-
ligent Key is not inserted in key slot), doors are unlocked with Intelligent Key button. When Intelligent Key unit
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 (Intelligent Key is inserted in key slot)
Auto door lock mode can be changed by “AUTO RELOCK TIMER” mode in “WORK SUPPORT”. Refer to BL-
81, "WORK SUPPORT" .
Panic Alarm Function
When ignition switch is OFF (ignition switch is not pressed) and key switch is OFF (Intelligent Key is not
inserted in key slot), Intelligent Key unit receives PANIC ALARM signal from Intelligent Key.
Intelligent Key unit sends alarm request signal to BCM via CAN communication line.
BCM turns on and off headlamp intermittently and sends 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 Intelligent Key unit receives any signal from Intelligent Key

When door request switch is pressed (Intelligent Key is within the outside key antenna detection area)
Panic alarm function mode can be changed by “PANIC ALARM DELAY” mode in “WORK SUPPORT”. Refer to
BL-81, "
WORK SUPPORT" .
