SERVICE PROCEDURES
CLEAN UP PROCEDURE
Roll of fold the driver side airbag towards the
steering wheel and tape the airbag module cover over
deployed bag.
Roll or fold the passenger airbag towards the
instrument panel surface and close the door over the
folded bag. Then tape the door shut.
Use a vacuum cleaner to remove any residual pow-
der from the vehicle interior. Work from the outside
in to avoid kneeling or sitting in a contaminated
area. Vacuum the heater and A/C outlets as well. If
the heater or air conditioner was in RECIRC mode at
time of airbag deployment, operate blower motor on
low speed and vacuum powder residue expelled from
the heater and A/C outlets. Multiple vacuum cleaning
may to necessary to decontaminate the interior of the
vehicle.

HANDLING AIRBAG MODULES
DEPLOYED AIRBAG MODULE
The vehicle interior may contain a very small
amount of sodium hydroxide powder, a by-product of
airbag deployment. Sodium hydroxide powder can
irritate the skin, eyes, nose and throat. Wear safety
glasses, rubber gloves, and long sleeved clothing
when cleaning any of the powder residue from the
vehicle.
If you find that the cleanup is irritating your skin,
run cool water over the affected area. Also, if you
experience nasal or throat irritation, exit the vehicle
for fresh air until the irritation ceases. If irritation
continues, see a physician.
UNDEPLOYED AIRBAG MODULE
The airbag modules must be stored in its original
special container until used for service. At no time
should a source of electricity be permitted near the
inflator on the back of an airbag module. When car-
rying or handling an undeployed airbag module, the
trim side of the airbag should be pointing away from
the body to minimize possibility of injury if acciden-
tal deployment occurs. Do not place undeployed air-
bag face down on a solid surface, the airbag will
propel into the air if accidentally deployment occurs.
MAINTENANCE INSPECTION
(1) Check the airbag warning lamp for proper
operation as follows:
(a) Turn ignition switch to the ON position, the
airbag warning lamp should light. If not, test the
system using a DRB llltscan tool and the proper
Body Diagnostic Procedures Manual.
(b) The airbag warning lamp lights, but fails to
go out after eight seconds. Test the system using a
DRB llltscan tool and the proper Body Diagnostic
Procedures Manual.
(c) After correcting active malfunction erase
stored Diagnostic Trouble Codes (DTC's).

DESCRIPTION AND OPERATION
REAR WINDOW DEFOGGER SYSTEM
For proper operation of the Rear Window Defogger
system refer to the Owner's Manual.
The system consists of a rear glass with two verti-
cal bus bars and a series of electrically connected
grid lines fired on the inside surface (Fig. 1). A con-
trol switch and a timing circuit are combined into a
single assembly.
Circuit protection is provided by a cartridge fuse
located in the Power Distribution Center (PDC) for
the heated grid circuit, and by a fuse in the fuse
block for the control circuit.
When the switch is turned to the ON position, cur-
rent is directed to the rear defogger grid lines. The
heated grid lines heat the rear glass to clear the sur-
face of fog or frost.CAUTION: Grid lines can be damaged or scraped
off with sharp instruments. Care should be taken in
cleaning glass or removing foreign materials,
decals or stickers. Normal glass cleaning solvents
or hot water used with rags or toweling is recom-
mended.
REAR WINDOW DEFOGGER SWITCH
The rear window defogger switch is a control
switch and timing circuit integrated into a single
panel mounted assembly (Fig. 2). Actuating the
switch energizes the circuit which allows current to
flow through the grid lines. Upon initial actuation for
approximately eight to ten minutes, or until either
the switch or ignition is turned off. An indicating
lamp illuminates a Light Emitting Diode (LED)
inlaid in the control switch.

DIAGNOSIS AND TESTING
GRID LINES
The horizontal grid lines and vertical bus bar lines
printed and fired on the inside surface of rear win-
dow glass (Fig. 5) comprise an electrical parallel cir-
cuit. The electrically conductive lines are composed of
a silver-ceramic material which when fired on glass
becomes bonded to the glass and is highly resistant
to abrasion. It is possible however, that a break may
occur in an individual grid line resulting in no cur-
rent flow through the line. To detect breaks in grid
lines the following procedure is required:
(1) Turn ignition ON and turn control switch to
ON. The LED should come on.
(2) Using a DC voltmeter with 0-15 volt range,
contact terminal (B) with the negative lead of the
voltmeter. With the positive lead of the voltmeter,
contact terminal (A) (Fig. 5). The voltmeter should
read 10-14 volts. A lower voltage reading indicates a
poor connection in the feed or the ground circuit.
(3) With the negative lead of the voltmeter, contact
a good body ground point. The voltage reading should
not change.
(4) Connect the negative lead of the voltmeter to
terminal (B) and touch each grid line at Mid-Point
with the positive lead. A reading of:
²Approximately 6 volts indicates the line is OK.
²0 volts indicates a break in line between Mid-
Point (C) and terminal (A).
²10-14 volts indicates a break between Mid-Point
(C) and terminal (B).
Move the lead toward the break and voltage will
change as soon as the break is crossed. Refer to (Fig.
5).
REAR WINDOW DEFOGGER SWITCH
The rear window defogger switch may be tested in
the vehicle or out of the vehicle, on the bench.
IN-VEHICLE TESTING
(1) Remove the switch from the instrument panel
but leave the switch connected, refer to Group 8E-In-
strument Panel and Systems, Auxiliary Switch Bezel
Removal and Installation.
(2) Turn the ignition switch ON.
(3) Using a voltmeter, check for battery voltage at
Pin 1 and 2 (Fig. 3).
(a) If OK, go to Step 4.
(b) If NOT OK, check fuse 7 in the fuse block
and the 40 Amp cartridge fuse in the Power Distri-
bution Center (PDC). If fuses are OK, check wiring
circuit. Refer to Group 8W-Wiring Diagrams.
(4) Check Pin 5, with switch in the ON position
there should be battery voltage and no voltage in the
OFF position.(a) If OK, go to Step 5.
(b) If NOT OK, no voltage in the ON position or
voltage in the OFF position. Replace the switch.
(5) Press switch to ON position. The indicator
lamp should come on and remain on for approxi-
mately 10 minutes. If the indicator lamp fails to light
or no voltage is present for approximately 10 min-
utes. Replace Rear Window Defogger Switch. Refer to
Group 8E-Instrument Panel and Systems, Auxiliary
Switch Bezel Removal and Installation.
BENCH TESTING
(1) First remove switch. Refer to Group 8E-Instru-
ment Panel and Systems, Auxiliary Switch Bezel
Removal and Installation.
(2) With switch removed from vehicle, use a
jumper wire and connect a 12 volt supply to Pin 1
and 2. Using a third jumper wire, ground Pin 3.
Refer to (Fig. 4) and the Rear Window Defogger
Switch and Harness Connector Pin Call-Outs table.
(3) Follow the same procedures used for IN-VEHI-
CLE TESTING, except for step Step 2.
REAR WINDOW DEFOGGER SYSTEM
Electrically heated rear window defogger operation
can be checked in the vehicle in the following man-
ner:
(1) Turn the ignition switch to the ON position.

(2) Connect an ammeter in series with the battery.
Push the rear window defogger switch to the ON
position (Fig. 2). A distinct increase in amperage
draw should be noted.
(3) The rear window defogger operation can be
checked by feeling the glass. A distinct difference in
temperature between the grid lines and adjacent
clear glass can be detected in three to four minutes
of operation.
(4) Using a DC voltmeter, connect the negative
lead to Point B, and the positive lead to Point A (Fig.
5). The voltmeter should read 10-14 volts.(5) Step 2, Step 3 or Step 4 above will confirm sys-
tem operation. Indicator light illumination means
that there is power available at the switch output,
and does not necessarily verify system operation.
(6) If turning the switch ON produced no distinct
current draw on the ammeter the problem should be
isolated in the following manner:
(a) Confirm the ignition switch is ON.
(b) Ensure that the heated rear glass feed wire
is connected to the terminal or pigtail and that the
ground wire is in fact grounded.
(c) Ensure that the cartridge fuse and control
circuit fuse are OK and all electrical connections
are secure.
(7) When the above steps have been completed and
the system is still inoperative, one or more of the fol-
lowing is defective:
(a) Rear Window Defogger Switch.
(b) All rear window grid lines would have to be
broken or one of the feed wires are not connected
for the system to be inoperative.
(8) If turning the switch ON produces severe volt-
meter deflection, the circuit should be closely checked
for a shorting condition.
(9) If the system operation has been verified but
indicator lamp does not light, replace the switch.
(10) For detailed wiring information, refer to group
8W-Wiring Diagrams.

DIAGNOSIS AND TESTING (Continued)

NOTE: The dealer must remove the module from
ªShip Modeº and place the RKE Module into either
the ªDealer Lotº storage or ªCustomer Usageº
modes of operation after receiving the vehicle from
the assembly plant. Refer to Group 8Q-Vehicle
Theft/Security Systems, Switching Operating
Modes/Configuring a New Module under Service
Procedures.
REMOTE KEYLESS ENTRY SYSTEM
The system allows locking and unlock of vehicle
door(s) and deck lid by remote control using a hand
held radio frequency (RF) transmitter. The vehicle
speed must be less than five miles per hour before
the deck lid can be unlatched with the transmitter.
The receiver may receive signals from four transmit-
ters. Each transmitter has its own code and the code
has been stored in memory. If the transmitter is
replaced or other transmitters are added, the code for
each unit must be learned.
REMOTE KEYLESS ENTRY TRANSMITTER
The transmitter has four buttons for operation
(Fig. 1). They are LOCK, UNLOCK, DECK LID
RELEASE, and PANIC.
²The UNLOCK button will unlock the driver door
and enable illuminated entry. Pushing and releasing
the button once will unlock the driver door. Pushing
and releasing the button two times within a five sec-
ond period will unlock all doors (double unlock acti-
vation enabled).
²Upon pressing the LOCK button, the horn will
sound a short chirp (if enabled) and flash the park
lamps to notify that the all door lock signal was
received and acted upon. Illuminated entry is can-
celled and the interior lamps are faded to off.
²Pushing and releasing the DECK LID
RELEASE button twice within a five second period
will actuate the decklid release solenoid, causing the
deck lid to be slightly ajar. If so desired, the decklid
may be set to release after one button push by the
dealer. For procedures on programming with the
DRB IIItscan tool, refer to the proper Body Diagnos-
tic Procedures Manual.
²Pushing the PANIC button will cause the panic
alarm to sound for three minutes, until the panic
button is pressed a second time, or until the vehicle
reaches a speed of 15 mph.
HORN CHIRP TOGGLE
Once the transmitters have been programmed, the
horn chirp can be enabled/disabled by sending the
horn chirp toggle operation code to the RKE Module.
This can be done using a DRB IIItscan tool or by
the customer. The horn chirp will enter the oppositestate of its current programmed state by receiving
this operation code. The RKE module is responsible
for keeping track of the horn chirp status.
DIAGNOSIS AND TESTING
REMOTE KEYLESS ENTRY MODULE
For procedures on diagnosing and testing the RKE
Module's RKE functions, refer to the proper Body
Diagnostic Procedures Manual.
DECKLID RELEASE SOLENOID
(1) Confirm operation of RKE transmitter(s) by
actuating Lock and Unlock functions.
(2) Confirm lead is connected to deck lid release
solenoid.
(3) Unplug lead, and use an ohmmeter to verify
continuity of connection between pin 2 of the harness
connector and ground. Refer to Group 8W-Wiring
Diagrams for Connector Pin-Outs.
(4) Connect test light to pin 1 of the harness con-
nector and actuate decklid release button on trans-
mitter. Refer to Group 8W-Wiring Diagrams for
Connector Pin-Outs.
(5) If test light comes on, the wiring circuit
between the RKE module and the solenoid is func-
tional, and the decklid solenoid should be replaced.
(6) If test light does not come on, refer to the
proper Body Diagnostic Procedures Manual for fur-
ther troubleshooting information.
SERVICE PROCEDURES

memory to determine whether a valid key is in the
ignition lock cylinder.
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.

the PCI bus is functional, that the Sentry Key Immo-
bilizer Module (SKIM) is placing the proper messages
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
8W-Wiring Diagrams for complete circuit descriptions
and diagrams.
(1) Check the fuses in the fuse block. If OK, go to
Step 2. If not OK, repair the shorted circuit or com-
ponent as required and replace the faulty fuse.
(2) Disconnect and isolate the battery negative
cable (Fig. 3). Unplug the wire harness connector at
the SKIM. Check for continuity between the ground
circuit cavity of the SKIM wire harness connector

are not connected to the system.
The chime will activate if the drivers door is
opened and:
²The key is in the ignition switch, with the igni-
tion switch in either the OFF or accessory (ACC)
position.
²The head lamps are ON.
The chime is integral to the instrument cluster.
DIAGNOSIS AND TESTING
FASTEN SEAT BELTS
To test the fasten seat belts function, turn the igni-
tion switch to the ON position with the driver's seat
belt unbuckled and fully retracted. The seat belt
warning lamp should light for four to eight seconds
and the tone should sound three to five times.
If the lamp does not light, check the connection at
the seat belt retractor and the LED in the instru-
ment cluster. Replace as necessary.
HEADLAMPS LEFT ON
These are the conditions that have to be met for
the headlamps on, chime function to work:
²Headlamps ON.
²Driver's door open.
²Key removed from the ignition switch.
Chime should sound until headlamps are turned
off or driver's door is closed.
If these conditions are met and there is still a
problem with the system, replace the instrument
cluster. Refer to Group 8E-Instrument Panel and
Systems, Instrument Cluster Removal and Installa-
tion.
KEY LEFT IN IGNITION SWITCH
To test the key left in ignition function, insert key
into the ignition and open the driver's door. Chime
should sound until key is removed from ignition or
driver's door is closed.
If these conditions are met and there is still a
problem with the system, replace the instrument
cluster. Refer to Group 8E-Instrument Panel and
Systems, Instrument Cluster Removal and Installa-
tion.
