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.

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.

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

If the wiper park switch has failed, the windshield
wipers will operate as follows:
²SWITCH OFF- Wipers stop in current location
regardless of the park signal.
²INTERMITTENT MODE- Wipers operate con-
tinuously or at low speed for one or more extra
wipes.
²LOW SPEED- Wipers operate at low speed.²HIGH SPEED- Wipers operate at high speed.
²WIPE AFTER WASH- Wipers operate at low
speed in any mode setting. Wipers operate only while
the wash button is depressed with switch in the OFF
mode and wipers stop in mid-cycle when button is
released.
The windshield wiper park switch and circuit is
monitored by the BCM. The park switch and circuit
can be tested using the WIPER SYSTEM DIAGNO-

DESCRIPTION - SECTION IDENTIFICATION AND
INFORMATION
The wiring diagrams are grouped into individual
sections. If a component is most likely found in a par-
ticular group, it will be shown complete (all wires,
connectors, and pins) within that group. For exam-
ple, the Auto Shutdown Relay is most likely to be
found in Group 30, so it is shown there complete. It
can, however, be shown partially in another group if
it contains some associated wiring.
Splice diagrams in Section 8W-70 show the entire
splice and provide references to other sections the
splices serves. Section 8W-70 only contains splice dia-
grams that are not shown in their entirety some-
where else in the wiring diagrams.

TROUBLESHOOTING TOOLS
When diagnosing a problem in an electrical circuit
there are several common tools necessary. These tools
are listed and explained below.
²Jumper Wire - This is a test wire used to con-
nect two points of a circuit. It can be used to bypass
an open in a circuit.
WARNING: NEVER USE A JUMPER WIRE ACROSS
A LOAD, SUCH AS A MOTOR, CONNECTED
BETWEEN A BATTERY FEED AND GROUND.
²Voltmeter - Used to check for voltage on a cir-
cuit. Always connect the black lead to a known good
ground and the red lead to the positive side of the
circuit.
CAUTION: Most of the electrical components used
in today's vehicles are Solid State. When checking
voltages in these circuits, use a meter with a 10 -
megohm or greater impedance rating.

INTEGRATED POWER MODULE
DESCRIPTION
The Integrated Power Module (IPM) is a combina-
tion of the Power Distribution Center (PDC) and the
Front Control Module (FCM). The IPM is located in
the engine compartment, next to the battery on this
model (Fig. 2). The power distribution center mates
directly with the Front Control Module (FCM) to
form the IPM Fuse and Relay Center. The power dis-
tribution center (PDC) is a printed circuit board
based module that contains fuses and relays, while
the front control module contains the electronics con-
trolling the IPM and other functions. This IPM con-
nects directly to the battery positive via a four pin
connector. The ground connection is via two other
connectors. The IPM provides the primary means of
voltage distribution and protection for the entire

The molded plastic IPM housing includes a base
and cover. The IPM cover is easily opened or removed
for service access by squeezing the two marked coverlatches and has a fuse and relay layout map integral
to the inside surface of the cover. This IPM housing
base and cover are secured in place by an IPM
mounting bracket. This mounting bracket is designed
to allow the IPM to rotate counter-clockwise once the
locking tab is disengaged. The IPM mounting bracket
is secured in place by bolts threaded into the left
front wheel house.
Replaceable components of the IPM assembly are
broken down into the following components: the
Power Distribution Center (PDC) (without fuses or
relays), the IPM cover, the Front Control Module
(FCM), the IPM mounting bracket, IPM bracket
retaining clips and the IPM assembly which includes
the power distribution center, the cover and FCM.
Refer to the Front Control Module in the Elec-
tronic Control Module sectionof this service
manual for information on the FCM.
OPERATION
All of the current from the battery and the gener-
ator output enters the Integrated Power Module
(IPM) via a four- pin connector on the bottom of the
module. The IPM cover is unlatched and opened or
removed to access the fuses or relays. Internal con-
nections of all of the power distribution center cir-
cuits is accomplished by a combination of bus bars
and a printed circuit board. Refer to the Wiring sec-
