SYSTEM (INTELLIGENT KEY SYSTEM)
The outside key antenna detection area of trunk open function is in
the range of approximately 80 cm (31.50 in) surrounding trunk
opener request switch (1). However, this operating range depends
on the ambient conditions.
KEY REMINDER FUNCTION
*:If the door closing impact shocks the door lock knob, or contacts against baggage with the door lock knob, it might activate the door
locks accidentally but unlock operation will be perform at these cases.
CAUTION:
• The above function operates when the Intelligent Key is inside the vehicle. However, there may be
times when the Intelligent Key cannot be detected, an d this function will not operate when the Intelli-
gent Key is on the instrument panel, rear parcel shelf, or in the glove box. Also, this system some-
times does not operate if the Intelligent Key is in the door pocket for the open door.
• The key reminder function is operated when the tr unk is opened/closed and the buzzers sound. If the
following operations are performed, the key remind er function is cleared and buzzer sounds are
stopped.
- Remote controller door lock butt on operation of Intelligent Key
- Remote controller door unlock butt on operation of Intelligent Key
- When the trunk is closed, the Intell igent Key is not inside the vehicle
- When any door is open
HAZARD AND BUZZER REMINDER FUNCTION
During trunk opening operation by request switch, the hazard warning lamps and Intelligent Key warning
buzzer will flash or sound as a reminder.
When trunk open by each request switch , IPDM E/R sounds Intelligent Key warning buzzer as a reminder and
transmits hazard request signal to BCM via CAN communication line.
BCM flashes hazard warning lamps as a reminder.

COMMON ITEM
COMMON ITEM : CONSULT Function (BCM - COMMON ITEM)INFOID:0000000009952500
CAUTION:
After disconnecting the CONSULT vehicle interface (VI) from the data link connector, the ignition must
be cycled OFF → ON (for at least 5 seconds) → OFF. If this step is not performed, the BCM may not go
to ”sleep mode”, potentially causing a di scharged battery and a no-start condition.
APPLICATION ITEM
CONSULT performs the following functions via CAN communication with BCM.
SYSTEM APPLICATION
