Check Headlamp FunctionBIS000XO
First perform the “SELF-DIAG RESULTS” in “BCM” with CONSULT-II, then perform the trouble diagnosis of
malfunction system indicated “SELF-DIAG RESULTS” of “BCM”. Refer to BCS-14, "
CAN Communication
Inspection Using CONSULT-II (Self-Diagnosis)" .
1. CHECK HEADLAMP OPERATION
Does headlamp come on when turning lighting switch “ON”?
YES or NO
YES >> Headlamp operation circuit is OK.
NO >> Check headlamp system. Refer to LT- 6 , "
HEADLAMP - XENON TYPE -" .
Removal and Installation of Intelligent Key UnitBIS001TH
REMOVAL
1. Remove the instrument driver lower panel. Refer to IP-10, "Component Parts Location" .
2. Disconnect Intelligent Key unit connector, remove screw and
Intelligent Key unit.
INSTALLATION
Install in the reverse order of removal.
Intelligent Key Battery ReplacementBIS001TI
DISASSEMBLY AND ASSEMBLY OF INTELLIGENT KEY
1. Release the lock knob at the back of the Intelligent Key and remove the mechanical key.
2. Insert a flat-blade screwdriver (A) wrapped with a close into the
slit of the corner and twist it to separate the upper part from the
lower part.
CAUTION:

Be careful not to touch the circuit board or battery termi-
nal.

The key fob is water-resistant. However, if it does get wet,
immediately wipe it dry.
3. Replace the battery with new one.
4. Align the tips of the upper and lower parts, and then push them
together until it is securely closed.
CAUTION:

When replacing battery, be sure to keep dirt, grease, and
other foreign materials off the electrode contact area.

After replacing the battery, check to make sure all Intelli-
gent Key functions work normally.

SECURITY INDICATOR

Warns that the vehicle has NATS.

In the vehicle without Intelligent Key system, security indicator always flashes with other than ignition
switch ON or START position. In the vehicle with Intelligent Key system, security indicator always flashes
with mechanical key removed condition (key switch OFF) and ignition knob released condition on LOCK
position (ignition knob switch OFF).
NOTE:
Because security indicator is highly efficient, the battery is barely affected.
Condition of Security Indicator
WITHOUT INTELLIGENT KEY SYSTEM
WITH INTELLIGENT KEY SYSTEM

In ignition knob operation with Intelligent Key, it always turns off with pushing ignition knob, and always
flashes with ignition knob released (ignition knob switch OFF) condition on ignition knob “LOCK” position.

In ignition knob operation with mechanical key, it turns off on the condition that mechanical key is inserted
in key cylinder, and always flashes with ignition knob released (ignition knob switch OFF) condition on
mechanical key removed condition.
System CompositionBIS000YD
The immobilizer function of the NATS consists of the following:

Ignition key (models without Intelligent Key system)

Mechanical key (models with Intelligent Key system)

NATS antenna amp.

Steering lock unit. (models with Intelligent Key system)

BCM

Intelligent Key unit (models with Intelligent Key system)

Engine control module (ECM)
