Driver Side Front Seatbelt Not Buckled -
Following the seatbelt reminder function, each time
the cluster detects an open circuit on the seat belt
indicator driver circuit (seatbelt switch open - seat-
belt unbuckled) with the ignition switch in the Start
or On positions, the indicator will be illuminated.
The seatbelt indicator remains illuminated until the
seat belt indicator driver input to the cluster is
closed to ground (seatbelt switch closed - seatbelt
buckled), or until the ignition switch is turned to the
Off position, whichever occurs first.
•
Actuator Test - Each time the cluster is put
through the actuator test, the indicator will be
turned on, then off again during the bulb check por-
tion of the test to confirm the functionality of the
LED and the cluster control circuitry.
The seatbelt switch input to the instrument cluster
circuitry can be diagnosed using conventional diag-
nostic tools and methods. For further diagnosis of the
seatbelt indicator or the instrument cluster circuitry
that controls the LED, (Refer to 8 - ELECTRICAL/
INSTRUMENT
CLUSTER - DIAGNOSIS AND
TESTING).
SECURITY INDICATOR
DESCRIPTION
A security indicator is standard equipment on all
instrument clusters. However, on vehicles not
equipped with the optional Vehicle Theft Security
System (VTSS), this indicator is mechanically dis-
abled. The security indicator is located in the Infor-
mation Center area of the instrument cluster, to the
left of center. The security indicator consists of a
stenciled cutout of the word “SECURITY” 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 lens behind the cutout in the opaque layer of
the overlay causes the “SECURITY” text to appear in
red through the translucent outer layer of the over-
lay when it is illuminated from behind by a Light
Emitting Diode (LED) soldered onto the instrument
cluster electronic 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 Security Sys-
tem (VTSS) is arming or is armed. On models
equipped with the Sentry Key Immobilizer System
(SKIS), the security indicator also gives an indication
to the vehicle operator of the status of the SKIS. This
indicator is controlled by a hard wired input to the
instrument cluster from the Central Timer Module
(CTM) on the VTSS indicator driver circuit and, if
the vehicle is so equipped, by a transistor on the
instrument cluster circuit board based upon elec-
tronic messages received by the cluster from the Sen-
try
Key Immobilizer Module (SKIM) over the
Programmable Communications Interface (PCI) data
bus. The security indicator Light Emitting Diode
(LED) receives battery current on the instrument
cluster electronic circuit board at all times 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
provided a path to ground by the CTM or by the
instrument cluster transistor. The security indicator
will be illuminated for the following reasons:
•
Bulb Test - If the vehicle is equipped with
SKIS, each time the ignition switch is turned to the
On position the security indicator is illuminated by
the instrument cluster for about three seconds based
upon an electronic lamp-on message received from
the SKIM as a bulb test. There is no bulb test per-
formed for models that are not equipped with the
optional SKIS.
•
VTSS Indication - During the seventeen sec-
ond VTSS arming function, the CTM will flash the
security indicator on and off repeatedly at a steady,
fast rate to indicate that the VTSS is in the process
of arming. Following successful VTSS arming, the
CTM flashes the security indicator on and off contin-
uously at a slower rate to indicate that the VTSS is
armed. The security indicator continues flashing at
the slower rate until the VTSS is disarmed or trig-
gered. If the VTSS alarm is triggered, the CTM will
flash the security indicator at a steady, fast rate for
up to eighteen minutes or until the triggering condi-
tion is removed, before returning to the slower,
armed flash rate.
•
SKIM Lamp-On Message - Each time the clus-
ter receives a lamp-on message from the SKIM, the
security indicator will be illuminated. The indicator
can be flashed on and off, or illuminated solid, as dic-
tated by the SKIM message. The indicator remains
illuminated solid or continues to flash until the clus-
ter receives a lamp-off message from the SKIM, or
until the ignition switch is turned to the Off position,
whichever occurs first. For more information on the
SKIS and the security indicator control parameters,
(Refer to 8 - ELECTRICAL/VEHICLE THEFT SECU-
RITY/SENTRY
KEY IMMOBILIZER SYSTEM -
OPERATION).
•
Actuator Test - Each time the instrument clus-
ter is put through the actuator test, the security indi-
cator will be turned on, then off again during the
bulb check portion of the test to confirm the function-
ality of the LED and the cluster control circuitry.
