POWER SEAT SYSTEM
DESCRIPTION
DESCRIPTION
The power seat system option allows the driver
and front seat passenger to electrically adjust their
seating positions for optimum control and comfort
using the power seat switches located on the out-
board seat cushion side shield of each front seat. The
driver side power front seat can be adjusted in eight
different directions: up, down, front up, front down,
rear up, rear down, forward, rearward and recliner
forward and rearward. The passenger side power
front seat can be adjusted in four different directions:
forward, rearward and recliner forward and rear-
ward. The power seat system receives battery current
through a 40 amp fuse in the Intelligent Power Mod-
ule and a 30 amp circuit breaker under the seat so
that the power seats remain operational, regardless
of the ignition switch position. WARNING: SOME VEHICLES ARE EQUIPPED WITH
SEATBACK MOUNTED AIRBAGS (Fig. 1). BEFORE
ATTEMPTING TO DIAGNOSE OR SERVICE ANY
SEAT OR POWER SEAT SYSTEM COMPONENT
YOU MUST FIRST DISCONNECT AND ISOLATE THE
BATTERY NEGATIVE CABLE. THEN WAIT TWO MIN-
UTES FOR THE SYSTEM CAPACITOR TO DIS-
CHARGE BEFORE FURTHER SYSTEM SERVICE.
THIS IS THE ONLY SURE WAY TO DISABLE THE
AIRBAG SYSTEM. FAILURE TO DO SO COULD
RESULT IN ACCIDENTAL AIRBAG DEPLOYMENT
AND POSSIBLE PERSONAL INJURY.
A eight-way driver side power seat is standard on
highline models and optional on others. This option
includes a six-way adjustable seat cushion track and
a two-way power seat back. The eight-way driver side power seat is also avail-
able with the heated seat and/or memory seat system
that automatically positions the power seat for two
different drivers. Refer to Heated Seatsfor more
information on the heated seat option. Refer to
Description - Memory System in this section for
more information on the memory seat system.

The power seat system includes the following com-
ponents: ² Power seat recliners
² Power seat switches
² Power seat tracks
² Circuit breaker
The power seat system with memory and heated
seat options includes the following components: ² Power seat recliner
² Power seat switch
² Power seat track.
² Memory Seat Mirror Module (MSMM)
² Memory set switch
² Heated Seat Module (HSM)
² Heated seat switch
² Electronic Vehicle Information Center (EVIC)
² Programmable Communications Interface (PCI)
data bus network Refer to Wiring Diagrams for complete circuit dia-
grams. Following are general descriptions and opera-
tions for the major components in the power seat
system and memory seat system.
DESCRIPTION - MEMORY SYSTEM
An electronic memory system is available on some
models. The memory system is able to store and
recall the driver side power seat positions (including
the power recliner position) and the driver outside
side view mirror position for two drivers. On vehicles
equipped with a factory radio, the memory system is also able to store and recall radio station presets for
two drivers. The memory system also will store and
recall the last station listened to for each driver, even
if it is not one of the preset stations.
The memory system will automatically return to
its preset settings when the corresponding numbered
button of the memory switch is depressed, or when
the doors are unlocked using the corresponding
Remote Keyless Entry (RKE) transmitter. A customer
programmable feature of the memory system allows
the RKE recall of memory features to be disabled, if
desired. This programmable feature is internal in the
EVIC module, which is located in the overhead con-
sole. A Memory Seat Mirror Module (MSMM) is used to
control and integrate the many electronic functions
and features included in the memory seat and mirror
systems. The memory system includes the following compo-
nents: ² Memory Seat Mirror Module (MSMM)
² Memory set switch
² Position potentiometers on the driver outside
side view mirror ² Position potentiometers on the driver side power
seat track and power seat recliner motors. ² Electronic Vehicle Information Center (EVIC)
² Radio receiver (if PCI data bus capable).
Certain functions of the memory system rely upon
resources shared with other electronic modules in the
vehicle over the Programmable Communications
Interface (PCI) J1850 data bus network. The PCI
data bus network allows the sharing of sensor infor-
mation. This helps to reduce wire harness complexity,
internal controller hardware, and component sensor
current loads. At the same time, this system provides
increased reliability, enhanced diagnostics, and
allows the addition of many new feature capabilities.
Initial diagnosis of these electronic modules or the
PCI data bus network requires the use of a DRBIII t
scan tool and the proper Diagnostic Procedures man-
ual. If this method does not prove conclusive, the use
of a automotive meter such as the Fluke t, the proper
wiring schematics and the service manual diagnostic
routines are required. The other electronic modules that may affect mem-
ory system operation are as follows: ² Body Control Module (BCM) - Refer toBody
Control Module in Electronic Control Modules for
more information. ² Powertrain Control Module (PCM) - Refer to
Powertrain Control Module in Electronic Control
Modules for more information. ² Transmission Control Module (TCM) - Refer
to Transmission Control Module in Electronic
Control Modules for more information.

ATTEMPTING TO DIAGNOSE OR SERVICE ANY
SEAT OR POWER SEAT SYSTEM COMPONENT
YOU MUST FIRST DISCONNECT AND ISOLATE THE
BATTERY NEGATIVE CABLE. THEN WAIT TWO MIN-
UTES FOR THE SYSTEM CAPACITOR TO DIS-
CHARGE BEFORE FURTHER SYSTEM SERVICE.
THIS IS THE ONLY SURE WAY TO DISABLE THE
AIRBAG SYSTEM. FAILURE TO DO SO COULD
RESULT IN ACCIDENTAL AIRBAG DEPLOYMENT
AND POSSIBLE PERSONAL INJURY.(1) If the vehicle is equipped with the memory sys-
tem and the driver side power seat exhibits a inter-
rupted or jerky motion, there is a possibility that the
wires leading from the memory seat module to the
memory seat motor are mis-wired. To check the con-
cern, obtain a DRBIII tscan tool and energize each
axis one at a time. If any axis stops in approximately
2 seconds (without hitting the end of travel), the
feedback for that axis may have an open, short or be
mis-wired. Check the wiring to that axis (module to
motor). Fix any wiring problems and retry that axis. (2) If any power seat is not operational in any
direction, check the power seat circuit breaker,
located under the trailing edge of the driver side
power seat. Refer to the Power Distribution section of
this service manual for the circuit breaker diagnosis
and testing procedure. (3) If the power seat circuit breaker is OK, check
for proper battery and ground connections at the
power seat switch and/or memory seat module. Fix
any wiring problems and retry. (4) Check the power seat system wire harness con-
nections and pins to ensure proper circuit continuity
and ground paths. For complete circuit diagrams,
refer to Wiring Diagrams .
(5) With the dome lamp on, apply the power seat
switch in the direction of the failure. If the dome
lamp dims, the seat may be jamming. Check under
and behind the seat for binding or obstructions. If
the dome lamp does not dim, proceed with testing of
the individual components and circuits in the power
seat system.
DIAGNOSIS AND TESTING - MEMORY SYSTEM
In order to obtain conclusive testing of the memory
system, the Programmable Communications Interface
(PCI) data bus network and all of the electronic mod-
ules that provide inputs to, or receive outputs from
the memory system components must be checked. The most reliable, efficient, and accurate means to
diagnose the memory system requires the use of a
DRB III tscan tool and the proper Diagnostic Proce-
dures manual. The DRB III tscan tool can provide confirmation that the PCI data bus is functional, that
all of the electronic modules are sending and receiv-
ing the proper messages on the PCI data bus, and
that the memory system is receiving the proper hard
wired inputs and relaying the proper hard wired out-
puts to perform its functions.
(1) If the driver power seat exhibits a interrupted
or jerky motion, there is a possibility that the wires
leading from the memory seat module to the memory
seat motor are mis-wired. To check the concern,
obtain a DRB III tscan tool and energize each axis
one at a time. If any axis stops in approximately 2
seconds (without hitting the end of travel), the feed-
back for that axis may have an open, short or be mis-
wired. Check the wiring to that axis (module to
motor). Fix any wiring problems and retry that axis.
Refer to Wiring Diagrams for complete circuit sche-
matic or connector pin-out information.
DRIVER SEAT SWITCH
DESCRIPTION
Vehicles equipped with a driver side power seat
utilize an eight-way power seat switch. This eight-
way power seat switch features two knobs ganged
together on the outboard seat cushion side shield
(Fig. 2). The switch is secured to the back of the seat cush-
ion side shield with two screws. However, the control

INSTALLATION
(1) Position the power seat switch onto the out-
board seat cushion side shield. (2) Install and tighten the screws that secure the
power seat switch to the inside of the outboard seat
cushion side shield. Tighten the screws to 1.5 N´m
(14 in. lbs.). (3) Reconnect the power seat wire harness connec-
tor to the power seat switch connector receptacle. (4) Position the outboard seat cushion side shield
onto the seat cushion frame (5) Install and tighten the screws that secure the
outboard seat cushion side shield to the seat cushion
frame. Tighten the screws to 1.5 N´m (14 in. lbs.). (6) Install the switch knobs on the switch control
levers, if equipped. (7) Reconnect the battery negative cable.
DRIVER POWER SEAT TRACK
DESCRIPTION
The eight-way driver side power seat option
includes a electrically operated power seat track
located under the driver side front seat. The front
power seat track on the driver side of the vehicle also
provides the mounting location for the Memory Seat/
Mirror Module (MSMM). The power seat circuit
breakers are mounted on the rear of the driver side
power seat track, just behind the seat rear trim
panel. The lower half of the power seat track is
secured to the floor panel via four studs and nuts
that must be accessed from the underside of the vehi-
cle. Four bolts secure the bottom of the seat cushion
pan to the upper half of the power seat track unit.
Four additional bolts secure the seat back frame to
the power seat track unit. The power seat track unit includes four reversible
electric motors that are secured to the upper half of
the track unit. Each motor moves the seat adjuster
through a combination of worm-drive gearboxes and
screw-type drive units. Each of the four power seat
track motors used on models equipped with the
optional memory system incorporates a position
potentiometer integral to the motor assembly, which
electronically monitors the motor position. This
enables the memory system to function by referenc-
ing the motor positions programmed into the memory
seat/mirror module. The front and rear of the seat are operated by two
separate vertical adjustment motors. These motors
can be operated independently of each other, tilting
the entire seat assembly forward or rearward; or,
they can be operated in unison by selecting the
proper power seat switch functions, which will raise
or lower the entire seat assembly. A third motor is the horizontal adjustment motor, which moves the
seat track in the forward and rearward directions.
The forth motor is the recliner adjustment motor,
which moves the seat back in the forward and rear-
ward directions.
The power seat track unit cannot be repaired, and
is serviced only as a complete unit. If any component
in this unit is faulty or damaged, the entire power
seat track unit must be replaced.
OPERATION
When the driver side power seat switch control
knob or knobs are actuated, a battery feed and a
ground path are applied through the switch contacts
to the power seat track or recliner adjuster motor.
The selected adjuster motor operates to move the
seat track or recliner through its drive unit in the
selected direction until the switch is released, or
until the travel limit of the adjuster is reached.
When the switch is moved in the opposite direction,
the battery feed and ground path to the motor are
reversed through the switch contacts. This causes the
adjuster motor to run in the opposite direction. No power seat switch should be held applied in any
direction after the adjuster has reached its travel
limit. The power seat adjuster motors each contain a
self-resetting circuit breaker to protect them from
overload. However, consecutive or frequent resetting
of the circuit breaker must not be allowed to con-
tinue, or the motor may be damaged. See the owner's manual in the vehicle glove box for
more information on the power seat switch functions
and the seat adjusting procedures.

DESCRIPTION
This vehicle is equipped with a Frontal Impact Air-
bag System, which utilizes the driver/passenger air-
bags and seatbelt pretensioners. This system is
designed to protect occupants in the event of a front
impact collision. These airbags and seatbelt preten-
sioners are all serviceable parts. If these pyrotechnics
are deployed or defective, they must be replaced, as
well as the Occupant Restraint Controller (ORC)
must be diagnosed following procedures outlined in
the service/diagnostic manuals.
Vehicles equipped with the Side Impact Airbag
System, the seat back assembly must be replaced, as
well as the Side Impact Airbag Control Module
(SIACM) must be diagnosed following procedures
outlined in the service/diagnostic manuals.
OPERATION
The Occupant Restraint Controller (ORC) controls
the driver/passenger airbags and seat belt tensioners.
If the ORC determines that the impact is severe
enough, the driver/passenger/side airbags and seat
belt tensioners will deploy. Once a deployment
occurs, these devices, and all damaged parts must be
replaced, as well as the ORC must be diagnosed fol-
lowing procedures outlined in the service/diagnostic
manuals.
The Side Impact Airbag Control Module (SIACM),
the seat back assemblies and all damaged parts must
be replaced, as well as the SIACM must be diagnosed
following procedures outlined in the service/diagnos-
tic manuals.

STANDARD PROCEDURE
STANDARD PROCEDURE - HANDLING
AIRBAGS
DEPLOYED AIRBAG
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
The airbags 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 carrying or han-
dling an undeployed airbag module, the trim side of
the airbag should be pointing away from the body to
minimize possibility of injury if accidental deploy-
ment occurs. Do not place undeployed airbag face
down on a solid surface, the airbag will propel into
the air if accidental deployment occurs.
STANDARD PROCEDURE - SERVICE AFTER AN
AIRBAG DEPLOYMENT
DRIVER AIRBAG
After a Driver Airbag has been deployed due to a
collision, the followingMUSTbe replaced:
²Driver Airbag²Clock Spring Assembly
²Steering Wheel
²Complete Steering Column Assembly w/Lower
Steering Column Coupler
All other airbag and vehicle components should be
closely inspected following any airbag deployment,
and should be replaced when visible damage is
incurred.
PASSENGER AIRBAG
After a Passenger Airbag has been deployed due to
a collision. the followingMUSTbe replaced:
²Passenger Airbag
²Instrument Panel and Pad Assembly
All other airbag and vehicle components should be
closely inspected following any airbag deployment,
and should be replaced when visible damage is
incurred.
SEAT AIRBAG
After a Seat Airbag has been deployed due to a col-
lision. the followingMUSTbe replaced:
²Complete Seat Back Assembly
All other airbag and vehicle components should be
closely inspected following any airbag deployment,
and should be replaced when visible damage is
incurred.
SEAT BELTS AND TENSIONERS
After a frontal impact where an airbag has been
deployed due to a collision. the followingMUSTbe
replaced:
²Front Seat Belt Buckle (driver and passenger)
with integral Tensioners.
All other seat belts should be closely inspected for
cuts, tears, fraying, or damage in any way following
any frontal impact or airbag deployment. The other
seat belts are to be replaced when visible damage is
incurred. Inspect the Lower Anchors and Tether for
CHildren (LATCH) child restraint anchors for dam-
age after an impact event and replace as needed.
CLEAN UP PROCEDURE
Roll or fold the airbag towards its mounting point
(i.e. instrument panel, steering wheel, or seat back).
Then tape the ripped cover over the deployed airbag
if applicable.
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 (Fig.
1). 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
