inside key antenna corresponding to the pressed door request switch and transmits the request signal to the
Intelligent Key. And then, check that the Intelligent Key is near the door.
 If the Intelligent Key is within the outside key antenna detection area, it receives the request signal and
transmits the key ID signal to the BCM via remote keyless entry receiver.
 BCM receives the key ID signal and compares it with the registered key ID.
 BCM lock/unlock each door and sounds Intelligent Key warning buzzer (lock: 2 time, unlock: 1 times) at the
same time as a reminder.
OPERATION CONDITION
If the following conditions are satisfied, door lock/unlock operation is performed when the request switch is

DIAGNOSIS SYSTEM (BCM)
The BCM records the following condition at the moment a particular DTC is detected.
 Vehicle Speed
 Odo/Trip Meter
 Vehicle Condition (BCM detected condition)
IGN Counter
IGN counter indicates the number of times that ignition switch is turned ON after DTC is detected.
 The number is 0 when a malfunction is detected now.
 The number increases like 1 → 2 → 3...38 → 39 after returning to the normal condition whenever ignition
switch OFF → ON.
 The number is fixed to 39 until the self-diagnosis results are erased if it is over 39.
