POWER SLIDING DOOR ADJUSTMENT
In order for the power sliding door system to func-
tion properly the door must move freely and
smoothly. The power sliding door system can accom-
modate for some minor changes in the effort required
to move the door. However, in extreme conditions the
door may need to be mechanically adjusted for proper
fit. (Refer to 23 - BODY/DOORS - SLIDING/SLID-
ING DOOR - ADJUSTMENTS).
If a problem exists with the power sliding door and
it is suspected to be extreme effort, check for proper
door alignment and adjustment first, then check the
door tracks and drive unit for free manual operation.
(Refer to 23 - BODY/DOORS - SLIDING/SLIDING
DOOR - ADJUSTMENTS) for detailed instructions.
LATCH
DESCRIPTION
One power latch is used for each power sliding door.
The latch is located on the trailing edge of the sliding
door assembly (Fig. 3). This power latch assembly is com-
prised of many different components which have the abil-
ity to perform the power cinch, release, lock, unlock and
safety related operations. These components are the door
latch, lock/unlock actuator, cinch/release actuator and
child lockout, pawl, ratchet and handle switches. The
pawl and ratchet switches are used to indicate the pri-
mary and secondary latched positions. The cinch latch
also provides a connection point for the interior handle,exterior handle and hold open latch cables. If any of the
components of the latch assembly are inoperative the
complete power latch assembly must be replaced.
OPERATION
The power latch performs the same operation as a full
manual door latch as well as power cinch, release, lock
and unlock operations. The power latch mounted actua-
tor cinches the door closed and latches it in its primary
latched position. During a power close cycle, the power
cinch actuator will not operate until the power sliding
door has reached its secondary latch position (deter-
mined by pawl and ratchet switches). During a power
open cycle, the power release actuator will stop once the
sliding door has moved from the primary latch position.
The power latch uses inputs from the lock/unlock
actuator, power sliding door control module and child
lockout, pawl, ratchet and handle switches to provide
safe power cinch and release operations. (Refer to 8 -
ELECTRICAL/POWER DOORS - OPERATION) for
additional information.

SLIDING DOOR MOTOR
DESCRIPTION
The door motor is located in the center of the
power sliding door (Fig. 8) and is comprised of three
parts. The three parts of the door motor assembly are
the motor, gear reduction and clutch assembly. The
door motor assembly provides the power and torque
to move the sliding door from the open/closed posi-
tion to full closed/open position, after the power
latching mechanism has released.
The door motor is replaced as a complete assembly,
which includes the DC motor, gear reduction and
clutch assemblies.
OPERATION
With the push of a power sliding door command
switch, the power sliding door control module will
signal the latch assembly to release the door from its
primary locked position. The door motor will then
take over to provide the power to open the door to its
full open or closed position. The gear reduction por-
tion of the motor assembly reduces the speed of the
motor from 5800 to 260 rpm and also increases the
torque to the lower drive unit. The clutch portion of
the motor assembly engages the motor to drive thedoor under power and disengages it so the door can
be moved easily under manual operation.

FULL OPEN SWITCH
DESCRIPTION
The full open switch is located in the hold open
latch (Fig. 10) under the sliding door lower hinge.
When the power sliding door control module receives
a ground signal input from the full open switch, and
as long as the cinching latch actuator is not in power
mode or the handle switch is open, the signal indi-
cates that the door is at the full open position.The full open switch is incorporated into the hold
open latch. If the full open switch is inoperative, the
entire hold open latch assembly must be replaced.
OPERATION
The full open switch is triggered by a pawl lever in
the hold open latch. When the full open switch is
closed (circuit to ground) the ratchet has engaged on
the hold open striker and the pawl lever has engaged
on the ratchet, locking the latch from opening and
holding the door in the full open position.
B-PILLAR SWITCH
DESCRIPTION
The B-pillar switches are located on the interior of
the vehicle, on the B-pillar trim panels. These
switches serve as an open and close command switch
for the appropriate power sliding door.
OPERATION
When the B-pillar switch is depressed a signal is
sent to the Body Control Module (BCM), this signal
is then sent to the power sliding door control module,
telling it to start a power open or close cycle. The
child lockout feature must be disabled and the slid-
ing door must be unlocked in order for the B-pillar
switch to function.
REMOVAL
(1) Disconnect and isolate the battery negative
cable.
(2) Using a trim stick (special tool # C-4755) or
equivalent, gently pry the leading upper edge of the
B-pillar switch away from the B-pillar trim.

LOWER DRIVE UNIT TRACK &
RACK
DESCRIPTION
The door track and rack assembly provides a mat-
ing rack gear (Fig. 22) for the lower drive unit to
engage. The track also accepts the lower hinge roll-
ers, which helps support the weight of the sliding
door as well as providing a smooth surface for the
hinge rollers to move upon. The lower door track is a
replaceable component.
OPERATION
With the start of a power sliding door open cycle,
the door motor drives the flex drive assembly. The
flex drive assembly drives the lower drive unit. A
metal drive gear which is part of the lower drive
unit, meshes with the door track rack teeth and
moves the sliding door into the full open position.

RESTRAINTS
DESCRIPTION
This vehicle is equipped with a Frontal Impact Air-
bag System, which utilizes the driver/passenger air-
bags, two front impact sensors, and seat belt
tensioners located in the front seat belt buckles. This
system is designed to protect occupants in the event
of a front impact collision. These airbags are all ser-
viceable parts. The tensioners are integral to the
front seat belt buckles. If these pyrotechnics are
deployed or defective, they must be replaced.
Vehicles equipped with the Side Impact Airbag
System utilize a curtain airbag, three side impact
sensors, and the Occupant Restraint Controller
(ORC) to determine if the airbag should be deployed.
Following a side impact event where the side airbag
was deployed, the headliner as well as the curtain
airbag must be replaced.
The occupant restraints include both active and
passive types. Active restraints are those which
require the vehicle occupants to take some action to
employ, such as fastening a seat belt; while passive
restraints require no action by the vehicle occupants
to be employed.
ACTIVE RESTRAINTS
The active restraints include:
²Front Seat Belts- Both front seating positions
are equipped with three-point seat belt systems
employing a lower B-pillar mounted inertia latch-
type retractor, height-adjustable upper B-pillar
mounted turning loops, a fixed lower seat belt anchor
secured to the lower B-pillar, and a traveling end-re-
lease buckle secured to the inboard side of the seat
cushion frame. The driver side front seat belt buckle
includes an integral Hall-effect seat belt switch that
detects whether the driver side front seat belt has
been fastened.²Rear Seat Belts- Both outboard rear second
and third seating positions are equipped with three-
point seat belt systems. The outboard seating posi-
tion belts employ a lower C or D-pillar mounted
inertia latch-type retractor, a fixed position upper C
or D-pillar mounted turning loop, and a fixed lower
seat belt anchor secured to the inboard side of the
seat cushion frame.
²Child Restraint Anchors- Also equipped in
this vehicle are two, fixed-position, child seat upper
tether anchors located on the lower seat cushion, in
the rear of the lower seat cushion. There is one
anchor integral to the back of the third row seat back
panel, one on each seat back panel. Two lower second
row anchors are also provided for each rear outboard
seating position. The lower anchors are integral to
the seat cushion frame and are accessed from the
front of the second row seat where the seat back
meets the seat cushion.
PASSIVE RESTRAINTS
The passive restraints available for this model
include the following:
²Dual Front Airbags- Multistage driver. front
passenger, and driver knee blocker airbags are avail-
able for this model. This airbag system is a passive,
inflatable, Supplemental Restraint System (SRS) and
vehicles with this equipment can be readily identified
by the ªSRS - AIRBAGº logo molded into the driver
airbag trim cover in the center of the steering wheel
and also into the passenger airbag door on the
instrument panel above the glove box. Vehicles with
the airbag system can also be identified by the airbag
indicator, which will illuminate in the instrument
cluster for about seven seconds as a bulb test each
time the ignition switch is turned to the ON position.
A pyrotechnic-type seat belt tensioner is integral to
the driver and passenger front seat belt buckle of all
models equipped with dual front airbags.
8O - 2 RESTRAINTSRS
²Occupant Classification Module- Vehicles
equipped with the Occupant Classification System
(OCS) include an Occupant Classification Module
(OCM) which is secured to a stamped steel mounting
bracket on the underside of the passenger side front
seat cushion frame.
²Occupant Restraint Controller- The Occu-
pant Restraint Controller (ORC) is also sometimes
referred to as the Airbag Control Module (ACM). The
ORC is located on a mount on the floor transmission
tunnel just underneath the instrument panel center
stack (Fig. 3).
²Passenger Airbag- The passenger airbag is
located on the instrument panel, beneath the instru-
ment panel top pad and above the glove box on the
passenger side of the vehicle (Fig. 3).
²Passenger Airbag Disabled (PAD) Indicator
- Vehicles equipped with the Occupant Classification
System (OCS) include a passenger airbag disabled
(PAD) indicator which is located in the instrument
panel center stack (Fig. 3).
²Passenger Knee Blocker- The passenger knee
blocker is a structural reinforcement that is integral
to and concealed within the glove box door (Fig. 3).
²Seat Belt Tensioner- A seat belt tensioner is
integral to both front seat belt buckles. The seat belt
buckles are secured to the inner seat frame sides,
beneath a cushion trim panel.
²Seat Weight Bladder and Pressure Sensor
Assembly- Vehicles equipped with the Occupant
Classification System (OCS) include a seat weight
bladder that is sandwiched between an insulator pad
on the top of the passenger side front seat pan and
the seat cushion foam padding. A short hose connects
the bladder to a pressure sensor which is secured to
the Occupant Classification Module (OCM) mounting
bracket on the underside of the passenger side front
seat cushion frame.
²Side Impact Sensors- Six side impact sensors
are used on vehicles equipped with the curtain air-
bags, three left side and three right side. The first
row side impact sensor is located in the B-pillar, just
above the front seat belt retractor. The second row
side impact sensor is located in the sliding side door
track opening, just in front of the C-pillar. The third
row side impact sensor is located behind the quarter
trim panel, above the rear tire wheel well, between
the C and D-pillars.
The ORC, the OCM, and the cluster each contain a
microprocessor and programming that allow them to
communicate with each other using the Programma-
ble Communications Interface (PCI) data bus net-
work. This method of communication is used by the
ORC for control of the airbag indicators.OPERATION
ACTIVE RESTRAINTS
The primary passenger restraints in this or any
other vehicle are the seat belts and child restraint
anchors. Seat belts and child restraint anchors are
referred to as an active restraint because the vehicle
occupants are required to physically fasten and prop-
erly adjust these restraints in order to benefit from
them. See the owner's manual in the vehicle glove
box for more information on the features, use and
operation of all of the active restraints.
PASSIVE RESTRAINTS
The passive restraints are referred to as a supple-
mental restraint system because they were designed
and are intended to enhance the protection for the
occupants of the vehicleONLYwhen used in con-
junction with the seat belts. They are referred to as
passive restraints because the vehicle occupants are
not required to do anything to make them operate;
however, the vehicle occupants must be wearing their
seat belts in order to obtain the maximum safety
benefit from the supplemental restraint system.
The supplemental restraint system electrical cir-
cuits are continuously monitored and controlled by a
microprocessor and software contained within the
Occupant Restraint Controller (ORC). An airbag indi-
cator in the ElectroMechanical Instrument Cluster
(EMIC) illuminates for about seven seconds as a bulb
test each time the ignition switch is turned to the
ON or START positions. Following the bulb test, the
airbag indicator is turned ON or OFF by the ORC to
indicate the status of the supplemental restraint sys-
tem. If the airbag indicator comes ON at any time
other than during the bulb test, it indicates that
there is a problem in the supplemental restraint sys-
tem electrical circuits. Such a problem may cause air-
bags not to deploy when required, or to deploy when
not required.
Deployment of the supplemental restraints
depends upon the angle and severity of an impact.
Deployment is not based upon vehicle speed; rather,
deployment is based upon the rate of deceleration as
measured by the forces of gravity (G force) upon the
impact sensors. When an impact is severe enough,
the microprocessor in the ORC signals the inflator of
the appropriate airbag units to deploy their airbag
cushions. The front seat belt tensioners are provided
with a deployment signal by the ORC in conjunction
with the front airbags. During a frontal vehicle
impact, the knee blockers work in concert with prop-
erly fastened and adjusted seat belts to restrain both
the driver and the front seat passenger in the proper
position for an airbag deployment. The knee blockers
also absorb and distribute the crash energy from the
