< FUNCTION DIAGNOSIS >[WITH I-KEY & SUPER LOCK]
DOOR LOCK FUNCTION
If the following conditions are not satisfied, door lock and unlock operation is not performed even if the request
switch is operated.
*: Even with a registered Intelligent Key remaining inside the vehicle, door locks can be unlocked from outside of the vehicle with a spare
Intelligent Key as long as key IDs are different.
OUTSIDE KEY ANTENNA DETECTION AREA
The outside key antenna detection area of door lock/unlock function
is in the range of approximately 80 cm (31.50 in) surrounding the
driver and passenger door handles (1) and the back door request
switch (2). However, this operating range depends on the ambient
conditions.
DOOR LOCK AND UNLOCK CONTROL
When the Intelligent Key detects that door request switch is pressed, it starts corresponding with outside key
antenna (request switch pressed door). Then, the Intelligent Key is checked to be near the door.
If the Intelligent Key is within the outside key antenna detection area, it receives the request signal and trans-
mits the key ID signal to the Intelligent Key unit. Intelligent Key unit receives the key ID signal and compares it
with the registered key ID. Intelligent Key unit sends door lock and unlock signal to BCM via CAN communica-
tion.
SUPER LOCK OPERATION
Super lock provides a higher anti-theft performance than a conventional power door lock system. The super
lock system is controlled by BCM and Intelligent Key unit.
When super lock is set, all doors cannot be opened from inside.
ANTI-HIJACK MODE
When door lock is unlocked, pressing LOCK buttons on Intelligent Key once will lock all doors. When door lock
is locked, pressing UNLOCK button on Intelligent Key once will unlock driver door. Pressing UNLOCK button
on Intelligent Key a second time within 5 seconds from the first time will unlock all doors and back door (hatch-
back) can be opened with back door opener switch or trunk (sedan) can be opened with trunk lid opener
switch.
CONVENIENCE MODE
When door lock is unlocked, pressing LOCK buttons on Intelligent Key once will lock all doors. When door lock
is locked, pressing UNLOCK button on Intelligent Key once will unlock all doors and back door (hatchback)
can be opened with back door opener switch or trunk (sedan) can be opened with trunk lid opener switch.
NOTE:
Anti-hijack mode can be set to ON or OFF with CONSULT-III. Once OFF, the convenience mode will be active.
For setting information with CONSULT-III, refer to DLK-53, "
CONSULT-III Function (INTELLIGENT KEY)". For
setting information without CONSULT-III, refer to Owner's Manual.
