PASSENGER AIRBAG MODULES, THERE ARE NO
SERVICEABLE PARTS WITH IN THE MODULES.
The Driver Airbag Module located on the steering
wheel is the most visible part of the system (Fig. 3).
The airbag module contains a housing to which the
cushion, inflator and cover are attached to.
The driver side inflator assembly is mounted from
the back of the module housing. When supplied with
the proper electrical signal the inflator assembly will
produce a gas and discharge it directly into the cush-
ion. A protective cover is fitted to the front of the
Driver Airbag Module and forms a decorative cover
in the center of the steering wheel. The Driver Air-bag Module is mounted directly to the steering
wheel.
The Passenger Airbag Module is located beneath
the decorative cover of the instrument panel, facing
the passenger seat (Fig. 3).
The passenger inflator assembly is within the mod-
ule housing. The module is mounted to the instru-
ment panel retainer and support structure. When
supplied with the proper electrical signal the inflator
will produce a gas and discharge it directly into the
cushion. A protective cover is fitted over the airbag
module and forms a decorative cover.

The Sentry Key transponder cannot be repaired
and, if faulty or damaged, it must be replaced.
SENTRY KEY IMMOBILIZER SYSTEM
INDICATOR LAMP
The Sentry Key Immobilizer System (SKIS) uses
the Vehicle Theft Security System (VTSS) indicator
LED to give an indication when the SKIS is faulty or
when the vehicle has been immobilized due to the
use of an invalid ignition key. The LED is controlled
by the instrument cluster circuitry based upon mes-
sages received from the Sentry Key Immobilizer
Module (SKIM) through the Body Control Module
(BCM) on the Programmable Communication Inter-
face (PCI) bus.
The SKIM sends messages to the instrument clus-
ter, via the BCM, to turn the LED on for about three
seconds when the ignition switch is turned to the ON
position as a bulb test. After completion of the bulb
test, the SKIM sends PCI bus messages to keep the
LED off for a duration of about one second. Then the
SKIM sends messages to the instrument cluster cir-
cuitry to turn the LED on or off based upon the
results of the SKIS self-tests. If the VTSS indicator
LED comes on and stays on after the bulb test, it
indicates that the SKIM has detected a system mal-
function and/or that the SKIS has become inopera-
tive. If the SKIM detects an invalid key when the
ignition switch is turned to the ON position, it sends
messages to the instrument cluster to flash the VTSS
indicator LED.
The SKIM can also send messages to the instru-
ment cluster to flash the LED and to generate a sin-
gle audible chime tone. These functions serve as an
indication to the customer that the SKIS has been
placed in its ªCustomer Learnº programming mode.
See Sentry Key Immobilizer System Transponder
Programming in this group for more information on
the ªCustomer Learnº programming mode.
The VTSS indicator LED uses a replaceable Light
Emitting Diode (LED) on the instrument cluster elec-
tronic circuit board. Refer to Group 8E - Instrument
Panel Systems for Cluster Lamp Removal and Instal-
lation. If the VTSS indicator LED comes on and
stays on after the bulb test function, diagnosis of the
SKIS should be performed with a DRB IIItscan tool
and the proper Body Diagnostic Procedures Manual.
TRIGGERING THE VTSS
After the VTSS is armed, any of the following will
trigger the system:
²Opening any door.
²Opening the hood.
²Removing the trunk lock cylinder.²Turning the ignition to the RUN/START position
with an invalid Sentry Key.
NOTE: The ignition switch can be turned to the
accessory position without triggering the alarm sys-
tem.

on the PCI bus, and that the Powertrain Control
Module (PCM) and the instrument cluster are receiv-
ing the PCI bus messages. Refer to the proper Body
Diagnostic Procedures Manual. Refer to Group
