< FUNCTION DIAGNOSIS >[WITH INTELLIGENT KEY SYSTEM]
DOOR LOCK FUNCTION
• To ensure the Intelligent Key works effectively, us
e within 80 cm range of each doors, however the operable
range may differ according to surroundings.
SELECTIVE UNLOCK FUNCTION
When a LOCK signal is transmitted from Intelligent Key, all doors will be locked.
When an UNLOCK signal is transmitted from Inte lligent Key once, driver's door will be unlocked.
Then, if an UNLOCK signal is transmitted from Intell igent Key again within 5 seconds, all other doors will be
unlocked.
When a liftgate signal is transmitted from Intelligent Key for more than 0.5 second, the back door operates to
the full open position. After opening, another signal will cause the back door to close.
HAZARD AND HORN REMINDER FUNCTION
When doors are locked or unlocked by Intelligent Key, 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 reminders do not operate if any door switch is ON (any door is OPEN).

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 BCM receives any signal from Intelligent Key
Panic alarm function mode can be changed by PANIC ALARM SET mode in “WORK SUPPORT”. Refer to
