1. When measuring voltage, wrap tin foil around the top of the neg- ative probe.Then press the foil against the wire with your finger.
2. Attach probe circuit tester (in Volt range) to middle portion of each filament.
3. If a filament is burned out, circuit tester registers 0 or battery voltage.
4. To locate burned out point, move probe to left and right along fil- ament. Test needle will swing abruptly when probe passes the
point.

• Drawing pen
• Heat gun
• Alcohol
• Cloth
REPAIRING PROCEDURE
1. Wipe broken heat wire and its surrounding area clean with acloth dampened in alcohol.
2. Apply a small amount of conductive silver composition to tip of drawing pen.
Shake silver composition container before use.
3. Place ruler on glass along broken line. Deposit conductive silver composition on break with drawing pen. Slightly overlap existing
heat wire on both sides [preferably 5 mm (0.20 in)] of the break.
4. After repair has been completed, check repaired wire for conti- nuity. This check should be conducted 10 minutes after silver
composition is deposited.
Do not touch repaired area while test is being conducted.
5. Apply a constant stream of hot air directly to the repaired area for approximately 20 minutes with a heat gun. A minimum dis-
tance of 3 cm (1.2 in) should be kept between repaired area and
hot air outlet.
If a heat gun is not available, let the repaired area dry for 24
hours.

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).
How to change hazard and horn reminder mode
With CONSULT-III
Refer to DLK-56, "
CONSULT-III Function (INTELLIGENT KEY)".
Without CONSULT-III
Refer to Owner's Manual for instructions.
AUTO DOOR LOCK FUNCTION
Auto Door Lock Function
When all doors are locked, ignition switch is OFF (ignition switch is not pressed) and key switch is OFF, doors
are unlocked with Intelligent Key button. When BCM does not receive the following signals within 30 seconds,
all doors are locked.
• Door switch is ON (door is opened)
• Door is locked
• Ignition switch is ON
• Key switch is ON (mechanical key is inserted in ignition key cylinder)
Auto door lock mode can be changed by DOOR LOCK -UNLOCK SET mode in “WORK SUPPORT”. Refer to

PANIC ALARM FUNCTION
When ignition switch is OFF (ignition switch is not pr essed) and key switch is OFF, BCM receives PANIC
ALARM signal from Intelligent Key through the remote keyless entry receiver and the Intelligent Key unit.
BCM turns on and off headlamp intermittently and transmits theft warning horn signal to IPDM E/R. Then,
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
