SIDE IMPACT AIRBAG
CONTROL MODULE
DESCRIPTION
The side airbag system is a safety devise designed
to reduce the risk of fatality or serious injury, caused
by a side impact of the vehicle.
Vehicles equipped with side impact airbags use two
Side Impact Airbag Control Modules (SIACM). One is
located on each respective side body B-pillar. Each
contains an impact sensor that senses a side impact
occurrence. The SIACM communicates with the ORC
via the PCI bus in order to notify the driver of any
potential side airbag system problem.
OPERATION
The impact sensor provides verification of the
direction and severity of the side impact. The right
side SIACM controls the right seat airbag. The left
side SIACM controls the left seat airbag. In the event
of a side impact the appropriate SIACM will send an
electronic signal to its airbag, deploying the airbag.
The SIACM communicates with the Occupant
Restraint Controller (ORC) via the PCI bus circuit.
The accelerometer pulses are sent to a micropro-
cessor, which contains a decision algorithm. When an
impact is severe enough to require airbag protection,
the SIACM microprocessor sends a signal to deploy
the side airbag that completes the electrical circuits
to the right or left side airbag. The sensor is cali-
brated for the specific vehicle and reacts to the sever-
ity and direction of the impact.
REMOVAL
NOTE: Diagnose the SIACM using the service/diag-
nostic manual.
(1) Disconnect and isolate the battery negative
cable terminal.
(2) Remove the lower B-pillar trim from the appro-
priate side of the vehicle. Refer to Body, Interior,
B-Pillar Lower Trim, Removal.
(3) Remove the three SIACM retaining screws and
remove the module from the vehicle.
(4) Disconnect the SIACM electrical connector.
INSTALLATION
WARNING: DO NOT INSTALL THE SIACM IF THE
MOUNTING LOCATION IS DEFORMED OR DAM-
AGED.
(1) Connect the SIACM electrical connector.
(2) Place the module in the slot on their respective
B-pillar. Install the three SIACM retaining screws.
Torque screws to 5.7 - 7.9 N´m (50 - 70 lbs.)
CAUTION: Use the correct screws when installing
the SIACM.
(3) Install the lower B-pillar trim on the appropri-
ate side of the vehicle. Refer to Body, Interior, B-Pil-
lar Lower Trim, Installation.
WARNING: DO NOT CONNECT THE BATTERY NEG-
ATIVE CABLE. REFER TO ELECTRICAL,

WARNING: ON VEHICLES EQUIPPED WITH AIR-
BAGS, REFER TO ELECTRICAL, RESTRAINTS,
WARNINGS, BEFORE ATTEMPTING COMPONENT
DIAGNOSIS OR SERVICE. FAILURE TO TAKE THE
PROPER PRECAUTIONS COULD RESULT IN ACCI-
DENTAL AIRBAG DEPLOYMENT AND POSSIBLE
PERSONAL INJURY.
NOTE: The following tests may not prove conclu-
sive in the diagnosis of this system. The most reli-
able, efficient, and accurate means to diagnose the
Sentry Key Immobilizer System involves the use of
a DRB IIITscan tool. Refer to the proper Body Diag-
nostic Procedures Manual.
The Sentry Key Immobilizer System (SKIS) and
the Programmable Communication Interface (PCI)
bus network should be diagnosed using a DRB IIIt
scan tool. The DRB IIItwill allow confirmation that
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) is receiving the PCI bus messages.
Refer to the proper Body Diagnostic Procedures man-
ual, and Wiring Diagrams for complete circuit
descriptions and diagrams.
(1) Check the fuses in the Integrated Power Mod-
ule (IPM). If OK, go to Step 2. If not OK, repair the
shorted circuit or component as required and replace
the faulty fuse.
(2) Disconnect and isolate the battery negative
remote cable from the remote terminal. Unplug the
wire harness connector at the SKIM. Check for con-
tinuity between the ground circuit cavity of the
SKIM wire harness connector and a good ground.
There should be continuity. If OK, go to Step 3. If not
OK, repair the open circuit to ground as required.
(3) Connect the battery negative cable. Check for
battery voltage at the fused B(+) circuit cavity of the
SKIM wire harness connector. If OK, go to Step 4. If
not OK, repair the open circuit to the fuse in the
IPM as required.
(4) Turn the ignition switch to the ON position.
Check for battery voltage at the fused ignition switch
output (run/start) circuit cavity of the SKIM wire
harness connector. If OK, use a DRB IIItscan tool
and the proper Body Diagnostic Procedures manual
to complete the diagnosis of the SKIS. If not OK,
repair the open circuit to the fuse in the IPM as
required.
DIAGNOSIS AND TESTING - VEHICLE THEFT
SECURITY SYSTEM
Refer to the appropriate wiring information. The
wiring information includes wiring diagrams, proper
wire and connector repair procedures, further details
on wire harness routing and retention, as well as
pin-out and location views for the various wire har-
ness connectors, splices and grounds. Using a DRB
IIItscan tool. Refer to the proper Body Diagnostic
Procedures Manual for test procedures.
HOOD AJAR SWITCH
REMOVAL
(1) Disconnect and isolate the battery negative
cable.
(2) Using a small flat blade screwdriver, pry trig-
ger switch from the bracket on the left fender well.
(3) Disconnect the hood ajar switch from the wire
connector and remove from vehicle.
INSTALLATION
(1) Connect the hood ajar switch to the wire conec-
tor.
(2) Press the hood ajar switch into position on the
bracket located on the left inner fender well.
(3) Reconnect the battery negative cable.
(4) Close the hood and check for proper operation.
TRANSPONDER KEY
DESCRIPTION
The Sentry Key Immobilizer System (SKIS) uses a
transponder chip that is integral to each ignition key
(Fig. 1) to communicate with the Sentry Key Immo-
bilizer Module (SKIM). Ignition keys are supplied
with the vehicle when it is shipped from the factory.
The transponder chip is undermolded within the
head of the key. This undermold is hidden beneath
an overmolded rubber cap.
OPERATION
Each Sentry Key has a unique transponder identi-
fication code permanently programmed into it by the
manufacturer. Likewise, the SKIM has a unique
9Secret Key9code programmed into it by the manu-
facturer as well. When a Sentry Key is programmed
into the memory of the SKIM, the SKIM stores the
transponder identification code from the Sentry Key,
and the Sentry Key learns the9Secret Key9code from
the SKIM. Once the Sentry Key learns the9Secret
Key9code of the SKIM, it is also permanently pro-
grammed into the transponder's memory. Therefore,
blank keys for the SKIS must be programmed by the

BAGS, REFER TO RESTRAINTS BEFORE ATTEMPT-
ING ANY STEERING WHEEL, STEERING COLUMN,
SEAT OR INSTRUMENT PANEL COMPONENT DIAG-
NOSIS OR SERVICE. FAILURE TO TAKE THE
PROPER PRECAUTIONS COULD RESULT IN ACCI-
DENTAL AIRBAG DEPLOYMENT AND POSSIBLE
PERSONAL INJURY.
(1) Check the fused B(+) fuse in the Integrated
Power Module (IPM). If OK, go to Step 2. If not OK,
repair the shorted circuit or component as required
and replace the faulty fuse.
(2) Check for battery voltage at the fused B(+) fuse
in the IPM. If OK, go to Step 3. If not OK, repair the
open fused B(+) circuit to the IPM fuse as required.
(3)
Open the power outlet door. Check for continuity
between the inside circumference of the power outlet
receptacle and a good ground. There should be continu-
ity. If OK, go to Step 4. If not OK, go to Step 5.
(4) Check for battery voltage at the insulated con-
tact located at the back of the power outlet recepta-
cle. If not OK, go to Step 5.
(5) Disconnect and isolate the battery negative
cable. Remove the appropriate bezel. Check for conti-
nuity between the ground circuit cavity of the power
outlet wire harness connector and a good ground.
There should be continuity. If OK, go to Step 6. If not
OK, repair the open ground circuit to ground as
required.
(6) Connect the battery negative cable. Check for
battery voltage at the fused B(+) circuit cavity of the
power outlet wire harness connector. If OK, replace
the faulty power outlet receptacle. If not OK, repair
the open fused B(+) circuit to the IPM fuse as
required.
REMOVAL
(1) Disconnect and isolate the battery negative
cable.
(2) Look inside and note position of the retaining
bosses (Fig. 5).
(3) Using external snap ring pliers with 90 degree
tips. Insert pliers with tips against bosses and
squeeze forcing bosses out of base.

gently rocking pliers. A tool can be made to do the
same. Refer to (Fig. 6).
(5) Disconnect the base wires.
(6) Set base aside. Remove light ring and discon-
nect wire.
INSTALLATION
(1) Position the mounting ring on the instrument
panel and feed the wires through the ring. Index the
cap and the mounting ring with the index tab at the9 o'clock position to the key in the instrument panel.
Install the ring.
(2) Connect the wires to the base. Orientate the
base alignment rib at the 11 o'clock position to mate
the groove in the mounting ring to the base.
(3) Push the base into the bezel until it locks in
place.
(4) Check operation of outlet or element and
install the 12 volt outlet cap.
