The dark outer layer of the overlay prevents the indi-
cator from being clearly visible when it is not illumi-
nated. A red Light Emitting Diode (LED) behind the
cutout in the opaque layer of the overlay causes the
icon to appear in red through the translucent outer
layer of the overlay when it is illuminated from
behind by the LED, which is soldered onto the
instrument cluster electronic circuit board. The seat-
belt indicator is serviced as a unit with the instru-
ment cluster.
OPERATION
The seatbelt indicator gives an indication to the
vehicle operator of the status of the driver side front
seatbelt. This indicator is controlled by a transistor
on the instrument cluster electronic circuit board
based upon the cluster programming and electronic
messages received by the cluster from the Airbag
Control Module (ACM) over the Programmable Com-
munications Interface (PCI) data bus. The seatbelt
indicator Light Emitting Diode (LED) is completely
controlled by the instrument cluster logic circuit, and
that logic will only allow this indicator to operate
when the instrument cluster receives a battery cur-
rent input on the fused ignition switch output (run-
start) circuit. Therefore, the LED will always be off
when the ignition switch is in any position except On
or Start. The LED only illuminates when it is pro-
vided a path to ground by the instrument cluster
transistor. The instrument cluster will turn on the
seatbelt indicator for the following reasons:
²Seatbelt Reminder Function- Each time the
cluster receives a battery current input on the fused
ignition switch output (run-start) circuit, the indica-
tor will be illuminated as a seatbelt reminder for
about seven seconds, or until the ignition switch is
turned to the Off position, whichever occurs first.
This reminder function will occur regardless of the
status of the electronic seat belt lamp-on or lamp-off
messages received by the cluster from the ACM.
²Seat Belt Lamp-On Message- Following the
seatbelt reminder function, each time the cluster
receives a seat belt lamp-on message from the ACM
indicating the driver side front seat belt is not fas-
tened with the ignition switch in the Start or On
positions, the indicator will be illuminated. The seat-
belt indicator remains illuminated until the cluster
receives a seat belt lamp-off message, or until the
ignition switch is turned to the Off position, which-
ever occurs first.
²Actuator Test- Each time the cluster is put
through the actuator test, the seatbelt indicator will
be turned on, then off again during the bulb check
portion of the test to confirm the functionality of the
LED and the cluster control circuitry.The ACM continually monitors the status of both
front seat belt switches to determine the proper air-
bag system response to a frontal impact of the vehi-
cle. The ACM then sends the proper seatbelt
indicator lamp-on and lamp-off messages to the
instrument cluster based upon the status of the
driver side front seat belt switch input. For further
diagnosis of the seatbelt indicator or the instrument
cluster circuitry that controls the indicator, (Refer to
8 - ELECTRICAL/INSTRUMENT CLUSTER - DIAG-
NOSIS AND TESTING). For proper diagnosis of the
seatbelt switches, the ACM, the PCI data bus, or the
electronic message inputs to the instrument cluster
that control the seatbelt indicator, a DRBIIItscan
tool is required. Refer to the appropriate diagnostic
information.
SECURITY INDICATOR
DESCRIPTION
A security indicator is standard equipment on all
instrument clusters, but is only functional on vehi-
cles equipped with the optional Vehicle Theft Secu-
rity System (VTSS). The security indicator is located
near the lower edge of the instrument cluster below
the tachometer and to the right of the fuel gauge.
The security indicator consists of a small stencil-like
round cutout in the opaque layer of the instrument
cluster overlay. The dark outer layer of the overlay
prevents the indicator from being clearly visible
when it is not illuminated. A red Light Emitting
Diode (LED) behind the cutout in the opaque layer of
the overlay causes the indicator to appear in red
through the translucent outer layer of the overlay
when it is illuminated from behind by the LED,
which is soldered onto the instrument cluster elec-
tronic circuit board. The security indicator is serviced
as a unit with the instrument cluster.
OPERATION
The security indicator gives an indication to the
vehicle operator when the Vehicle Theft Alarm (VTA)
portion of the Vehicle Theft Security System (VTSS)
is arming or is armed. This indicator is controlled on
the instrument cluster circuit board based upon a
hard wired input to the cluster from the Body Con-
trol Module (BCM) on the VTSS indicator driver cir-
cuit. The security indicator Light Emitting Diode
(LED) receives battery current on the instrument
cluster electronic circuit board through the fused
B(+) circuit at all times; therefore, the LED will
remain functional regardless of the ignition switch
position. The LED only illuminates when it is pro-
vided a path to ground by the BCM. The security

reliable, efficient, and accurate means to diagnose
the BCM, the EMIC, the PCM, and the PCI data bus
network inputs and outputs related to the various
exterior lighting systems requires the use of a
DRBIIItscan tool. Refer to the appropriate diagnos-
tic information.
When diagnosing the exterior lighting circuits,
remember that high generator output can burn out
bulbs rapidly and repeatedly; and, that dim or flick-
ering bulbs can be caused by low generator output or
poor battery condition. If one of these symptoms is a
problem on the vehicle being diagnosed, be certain to
diagnose and repair the battery and charging system
as required. Also keep in mind that a good ground is
necessary for proper lighting operation. If a lighting
problem is being diagnosed that involves multiple
symptoms, systems, or components the problem can
often be traced to a loose, corroded, or open ground.
For complete circuit diagrams, refer to the appropri-
ate wiring information. The wiring information
includes wiring diagrams, proper wire and connectorrepair procedures, details of wire harness routing
and retention, connector pin-out information and
location views for the various wire harness connec-
tors, splices and grounds.

point. When the relay coil is de-energized, spring
pressure returns the movable contact point back
against the fixed normally closed contact point. A
resistor is connected in parallel with the relay coil in
the relay, and helps to dissipate voltage spikes and
electromagnetic interference that can be generated as
the electromagnetic field of the relay coil collapses.
The front fog lamp relay terminals are connected
to the vehicle electrical system through a connector
receptacle in the Junction Block (JB). The inputs and
outputs of the front fog lamp relay include:
²Common Feed Terminal- The common feed
terminal (30) receives battery current at all times
from a fuse in the JB through a fused B(+) circuit.
²Coil Ground Terminal- The coil ground termi-
nal (85) is connected to a control output of the pre-
mium Body Control Module (BCM) through a front
fog lamp relay control circuit. The BCM controls
front fog lamp operation by controlling a ground path
through this circuit.
²Coil Battery Terminal- The coil battery ter-
minal (86) receives battery current at all times from
a fuse in the JB through a fused B(+) circuit.
²Normally Open Terminal- The normally open
terminal (87) is connected to the front fog lamps
through a front fog lamp relay output circuit and
provides battery current to the front fog lamps when-
ever the relay is energized.
²Normally Closed Terminal- The normally
closed terminal (87A) is not connected in this appli-
cation.
The front fog lamp relay can be diagnosed using
conventional diagnostic tools and methods.

tromagnet) should be 75 8 ohms. If OK, go to Step
4. If not OK, replace the faulty relay.
(4) Connect a battery to terminals 85 and 86.
There should now be continuity between terminals
30 and 87, and no continuity between terminals 87A
and 30. If OK, reinstall the relay and use a DRBIIItscan tool to perform further testing. Refer to the
appropriate diagnostic information.

HEADLAMP LEVELING MOTOR
DESCRIPTION
The headlamp leveling motor is located on the rear
inboard side of each headlamp unit on models
equipped with the headlamp leveling system, which
is available only in certain markets where required
(Fig. 31). The motor is encased within a molded plas-
tic housing and is secured by an integral wedge-type
mounting boss on its forward surface to a flanged
receptacle on the back of the headlamp unit housing.
A rubber seal around the circumference of the
mounting boss is compressed and seals the motor to
the headlamp unit when the boss is properly
installed in the flanged receptacle. The outside of the
motor housing features an integral molded connector
receptacle on its rearward surface, a hex-headed
adjusting screw extends from the top of the housing,
and a plastic pushrod with a ball formation on its
free end extends from the center of the mounting
boss at the front. Within the motor housing is a
12-volt Direct Current (DC) servo motor, an elec-
tronic controller board that includes the motor logic
circuits, and an integral screw-drive transmission.
The headlamp leveling motor is connected to the
vehicle electrical system through a dedicated take
out and connector of the front fascia wire harness.
The headlamp leveling motor cannot be repaired
and, if faulty or damaged, the unit must be replaced.
