System Diagram
Door Lock/Unlock Function • When door lock/unlock button of the Intelligent Key is pr essed, lock signal or unlock signal is sent from Intel-
ligent Key to Intelligent Key unit.
• 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 and sounds Intelligent Key warning buzzer(s) (lock: 2 times, unlock: 1 time) at the same time.
• When BCM receives the door lock/unlock signal, it oper ates door lock actuator and flashes the hazard warn-
ing lamp (lock: 2 times, unlock: 1 time) at the same time as reminder.
Operation Condition
Hazard and Buzzer Reminder When all doors are locked or unlocked by Intelligent Ke y button, Intelligent Key unit sends hazard request sig-
nal to BCM via CAN communication line.
BCM flashes hazard warning lamps as a reminder and Intelligent Key unit sounds Intelligent Key warning
buzzer as a reminder.
Operating function of hazard and buzzer reminder
Auto Door Lock Function When all doors are locked, ignition knob switch is OFF (when ignition switch is not pressed) and key switch is
OFF (when mechanical key is out of ignition key cyli nder), doors are unlocked with Intelligent Key button.
When Intelligent Key unit does not receive the following signals within 1 minute, all doors are locked.
• Door switch is ON (door is opened)
• Trunk lamp switch (sedan) is ON (trunk is opened)
• Door is locked
• Ignition knob switch is ON (ignition switch is pressed)
• Key switch is ON (mechanical key is inserted in ignition switch)
Auto door lock mode can be changed by “AUTO RELOCK TIMER” mode in “WORK SUPPORT”. Refer to BL-117, " CONSULT-III Application Item " .
Panic Alarm Function When ignition knob switch is OFF (ignition switch is not pressed), or key switch is OFF (mechanical key is not
inserted in key cylinder), pressing and holding the panic alarm button on Intelligent Key will send a panic alarm
signal to Intelligent Key unit.
Intelligent Key unit sends alarm request signal to BCM via CAN communication line.
BCM sends headlamp request signal and horn signal to IPDM E/R. Then, IPDM E/R turns on and off head-
lamp and horn intermittently. Intelligent Key button operation Hazard warning lamp flash Intelligent Key warning buzzer(s) Horn
