LATCH
DESCRIPTION
The power cinch/release latch performs the same
features as a manual liftgate latch as well as the
power cinch and / or release capability. A second type
of power latch can also be found on some vehicles,
this latch is designed to perform a power release
only. The power cinch and release capability is
accomplished by an actuator mounted to the leading
edge of the latch assembly. The latch is located in the
lower center of the power liftgate assembly (Fig. 8)
and contains integral pawl and ratchet switches. The
ratchet switch also acts as a liftgate ajar switch. The
power latch assembly can be serviced as a complete
assembly, latch without actuator or just the actuator.
OPERATION
On the power cinch/release latch, the latch
mounted actuator provides the torque required to
close the power liftgate from the secondary to the pri-mary closed and latched position. On the power
cinch/release latch and the power release only latch,
the actuator releases the liftgate from the primary
closed and latched position to the fully unlatched and
movable position.
REMOVAL
(1) Disconnect and isolate the battery negative
cable.
(2) Open the liftgate and remove the liftgate trim
panel, (Refer to 23 - BODY/DECKLID/HATCH/LIFT-
GATE/TAILGATE/TRIM PANEL - REMOVAL).
(3) Disconnect the power latch electrical connector
(Fig. 9).
(4) Remove the power latch retaining bolts.
(5) Disconnect the liftgate lock cylinder link rod
(Fig. 9) from the key cylinder or latch assembly. To
disconnect from latch, rotate the plastic retaining clip
90 É to unsnap clip from linkrod. Then pull link rod
straight out of latch arm.

LATCH ACTUATOR
DESCRIPTION
The power cinch and/or power release latch (Fig.
11) is made possible by a latch actuator attached to
the leading edge of the power latch assembly. This 12
volt latch actuator contains a small drive gear that
meshes with the latch assemblies internal gears to
perform the power cinch close / power release opera-
tions. (Refer to 8 - ELECTRICAL/POWER DOORS/
LATCH - DESCRIPTION) for additional information.
The power cinch/release actuator is serviceable com-
ponent.
OPERATION
During a power close cycle, the power cinch actua-
tor provides the torque required to close the power
liftgate from the secondary to the primary closed and
latched position. During a power open cycle, the
power release actuator releases the liftgate from the
primary closed and latched position to the fully
unlatched and movable position.

POWER LOCKS
DESCRIPTION
POWER LOCKS
The power lock system allows all of the doors to be
locked or unlocked electrically by operating a switch
on either front door trim panel. The power lock sys-
tem receives non-switched battery current through a
fuse in the Integrated Power Module (IPM), so that
the power locks remain operational, regardless of the
ignition switch position.
The Body Control Module (BCM) locks the doors
automatically when the vehicle is driven beyond the
speed of 25.7 Km/h (15 mph), all doors are closed, the
accelerator pedal is depressed and the door lock actu-
ation had not been previously activated. The rolling
door lock feature is customer programmable.
This vehicle also offers several customer program-
mable features, which allows the selection of several
optional electronic features to suit individual prefer-
ences.
The power lock system for this vehicle can also be
operated remotely using the available Remote Key-
less Entry (RKE) system radio frequency transmit-
ters, if equipped.
AUTOMATIC DOOR LOCKS
When enabled, this feature will lock all of the door
locks if all of the doors are closed and the vehicle
speed goes above 25.7 km/h (15 mph). If a door
unlock has occurred, then the BCM will perform
another auto lock, if the doors did not electrically
unlock, another auto lock will not occur.
DOOR LOCK INHIBIT
When the key is in the ignition (in any switch posi-
tion) and either front door is opened, the door lock
switches LOCK functions are disabled. The
UN-LOCK functions are still functional. This protects
against locking the vehicle with the key still in the
ignition. The RKE key fob will still lock the doors.
After the key is removed from the ignition or the
doors are closed, the power door locks will operate
normally.
REMOTE KEYLESS ENTRY
The Remote Keyless Entry (RKE) system allows
the use of a remote battery-powered radio transmit-
ter to communicate with the BCM to actuate the
power lock system.
The RKE transmitters are also equipped with a
Panic button. If the Panic button on the RKE trans-
mitter is depressed, the horn will sound and the
exterior lights will flash on the vehicle for about
three minutes, or until the Panic button is depressed
8N - 20 POWER LOCKSRS

a second time. Pressing the Panic button also acti-
vates the courtesy lamps. Pressing the Panic button
again stops the exterior lamps from flashing and the
horn from sounding. However, the courtesy lamps
will remain illuminated until either the BCM times
out lamp operation or until the turning of the igni-
tion. The panic feature will operate if the ignition is
ON, but only if the Panic button is pressed prior to
starting the vehicle. A vehicle speed of about 25.7
km/h (15 miles-per-hour) will also cancel the panic
event.
The RKE system can also perform other functions
on this vehicle. If the vehicle is equipped with the
optional Vehicle Theft Security System (VTSS), the
RKE transmitter will arm the VTSS when the Lock
button is depressed, and disarm the VTSS when the
Unlock button is depressed.
The RKE system includes two transmitters when
the vehicle is shipped from the factory, but the sys-
tem can retain the vehicle access codes of up to a
total of eight transmitters. If an RKE transmitter is
inoperative or lost, new transmitter vehicle access
codes can be programmed into the system using a
DRB IIItscan tool.
This vehicle also offers several customer program-
mable features, which allows the selection of several
optional electronic features to suit individual prefer-
ences. Customer programmable feature options
affecting the RKE system include:
²Automatic Door Lock- Customer programma-
ble feature that allows the BCM to perform an auto-
matic door lock if the vehicle speed is above 25.7
km/h (15 miles-per-hour).
²Automatic Door Unlock On Exit- Customer
programmable feature that allows the BCM to per-
form an automatic door unlock if the vehicle speed is
0, vehicle in park and driver door is opened.
²Flash Lights with Lock and Unlock- Allows
the option of having the park lamps flash as an opti-
cal verification that the RKE system received a valid
Lock request or Unlock request from the RKE trans-
mitter, or having no optical verification.
²Programming Additional Transmitters-
Allows up to a total of four transmitter vehicle access
codes to be stored.
²Remote Unlock Sequence- Allows the option
of having only the driver side front door unlock when
the RKE transmitter Unlock button is depressed the
first time. The remaining doors unlock when the but-
ton is depressed a second time within 5 seconds of
the first unlock press. Another option is having all
doors unlock upon the first depression of the RKE
transmitter Unlock button.
²Sound Horn on Lock- Allows the option of
having the horn sound a short chirp as an audible
verification that the RKE system received a validLock request from the RKE transmitter, or having no
audible verification.
OPERATION
POWER LOCKS
The Body Control Module (BCM) locks or unlocks
the doors when an actuation input signal from a door
lock switch, Central Lock key cylinder or Remote
Keyless Entry (RKE) is received. The BCM turns on
the output drivers and provides a voltage level to the
door lock motor for a specified time.
REMOTE KEYLESS ENTRY
The RKE transmitter uses radio frequency signals
to communicate with the SKREEM module. The
SKREEM is on the PCI bus. When the operator
presses a button on the transmitter, it sends a spe-
cific request to the SKREEM. In turn, the SKREEM
sends the appropriate request over the PCI bus to
the following:
²Integrated Power Module (IPM)- to activate
the park lamps, the headlamps and the horn for the
horn chirp.
²Power Liftgate Module (PLGM)- to control
the liftgate lock and unlock functions.
After pressing the lock button on the RKE trans-
mitter, all of the door locks will lock, the illuminated
entry will turn off (if all doors are closed) and the
vehicle theft security system (if equipped) will arm.
Pressing the unlock button one time will unlock
the driver door, or all doors based on the customer
programmable feature enabled, the illuminated entry
will turn on the courtesy lamps and the vehicle theft
security system (if equipped) will disarm. Pressing
the unlock button a second time, the remaining door
locks will unlock.
If the vehicle is equipped with the memory system,
the memory message will identify which transmitter
(1 or 2) sent the signal.
ROLLING CODE
The rolling code feature changes part of the trans-
mitter message each time that it is used. The trans-
mitter message and the receiver message increment
together. Under certain conditions with a rolling code
system, such as pressing a button on the RKE trans-
mitter over 255 times outside of receiver range or
replacing the battery, the receiver and transmitter
can fall out of synchronization. To re-synchronize,
press and release the UNLOCK button on the RKE
transmitter repeatedly (it may take up to eight
cycles) while listening carefully for the power door
locks in the vehicle to cycle, indicating that resyn-
chronization has occurred.

POWER LOCKS (Continued)

The lock function works from the RKE transmitter
even in an out of synchronization condition, therefore
it could be verified by pressing the LOCK button on
the RKE key fob.
DOOR CYLINDER LOCK
SWITCH - EXPORT
DESCRIPTION
The Door Cylinder Lock Switch (If equipped) is
used to:
²Unlock/Lock all the doors via the Central Lock-
ing feature.
²Arm/Disarm the Vehicle Theft Security System.
²Trigger the Illuminated Entry feature.
The door cylinder lock switch is mounted to the
rear of the driver door lock cylinder. When installed
on the rear of the cylinder, there is a tab on the lock
cylinder that aligns with the switch to prevent it
from turning. An anti-rotating device. The door cylin-
der lock switch is a one time use switch. Once it is
removed from the rear of the door lock cylinder, it
may not be reinstalled and a new switch must be
used.
OPERATION
When the Door Cylinder Lock Switch is turned
either way using the door key cylinder, the BCM
reads a direct message signal from the switch.
If turning the key cylinder once, toward the front
of the vehicle, this will:
(1) Mechanically unlock the door lock.
(2) Disarm the Vehicle Theft Security System (if
equipped).
(3) Turn on the Illuminated Entry (if equipped) for
approximately 30 seconds.
If the key cylinder is turned to the unlock position
(toward the front of vehicle) twice within two sec-
onds, all the doors and liftgate will unlock (if
equipped with the central locking feature).
To lock the vehicle using the door cylinder lock
switch, turn the key cylinder toward the rear of the
vehicle once. This will lock the door that you are
using the key on. If equipped with the central locking
feature, this will lock all the other doors and liftgate.
Furthermore, this will arm the vehicle theft security
system and turn off the illuminated entry.

OPERATION
POWER SEAT SYSTEM
The power seat system receives battery current
through fuse #22 in the Integrated Power Module
(IPM) and a circuit breaker under the front seats,
regardless of the ignition switch position.
When a power seat switch control knob or knobs
are actuated, a battery feed and a ground path are
applied through the switch contacts to the appropri-
ate power seat track adjuster motor. The selected
adjuster motor operates to move the seat track
through its drive unit in the selected direction until
the switch is released, or until the travel limit of the
seat track 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 seat track has reached its travel
limit. The power seat adjuster motor each contain a

POWER SLIDING DOOR
SYSTEM
DESCRIPTION
Some vehicles are equipped with a power sliding
door system. Vehicles may be equipped with only a
right side power sliding door or a right and left side
power sliding doors. The components of the power
sliding door system are:
²Door motor assembly
²Latch assembly
²Sliding door control module
²Lower drive unit assembly
²Flex drive assembly
²Wire harness and track
²Lower drive unit track and rack assembly
²Full open switch
²B-pillar switch
²Overhead console switch
²Key fob switches (Fig. 1)
²Pawl switch
²Ratchet switch
²Child lockout and handle switchesEach power sliding door has its own door control
module, located in the center of the door behind the
door trim panel. (Refer to 8 - ELECTRICAL/ELEC-
TRONIC CONTROL MODULES/DOOR CONTROL
MODULE - DESCRIPTION) The power sliding door
motor is located in the front portion of the door, on
the inner door panel sheet metal. The latch assembly
is located in the rear of the power sliding door, near
the body line. The lower drive unit is attached to the
lower door hinge. The flex drive assembly connects
the door motor to the lower drive unit. The wire har-
ness and track and the lower drive unit track are vis-
ible with the door open in the lower door sill area.
The power sliding door full open switch is located
under the lower drive unit and is part of the hold
open latch assembly. The pawl, ratchet, handle and
child lockout switches are all located on the power
sliding door latch assembly. The B-pillar switch is an
open and close command switch located on the inte-
rior B-pillar trim. The overhead console switch, is an
open and close command switch located in the vehi-
cle's overhead console.
Software technology has enabled the power sliding
door control module to detect resistance to door

travel. This allows the power sliding door to stop and
reverse direction any time an obstruction is felt or
any of the command switches are operated (while
closing only). Battery voltage is supplied to the power
sliding door system through a 40 amp fuse, located in
the Integrated Power Module (IPM) assembly. The
child lockout switch prevents children from opening
or actuating the power sliding door system when
desired. In the unlikely event that the power sliding
door system develops a fault, the power sliding door
can still be operated manually from the interior or
exterior door handle, just like a standard manual
sliding door.
The power sliding door control module communi-
cates on the Programmable Communication Interface
(PCI) Data Bus Circuit. Therefore, the power sliding
door control module can generate and store its own
Diagnostic Trouble Codes (DTC). A diagnostic scan
tool, such as the DRB IIItis used to read and diag-
nose these trouble codes.
NOTE: It may be possible to generate Sliding Door
Diagnostic Trouble Codes during normal power
sliding door operation. Refer to the Body Diagnos-
tic Manual for a complete list of diagnostic routines.
For additional information, (Refer to 8 - ELECTRI-
CAL/POWER DOORS - OPERATION). Refer to the
appropriate wiring information for complete circuit

OPERATION
With the push of a power sliding door open/close
command switch (key fob, overhead console or B-pil-
lar mounted) a signal is sent out to the Body Control
Module (BCM). The BCM then sends a signal out on
the Programmable Communication Interface (PCI)
Data Bus circuit to the power sliding door module.
The power sliding door module then signals the
power sliding door latch to release the door to the
unlatched and movable position. The motor then
starts an open cycle.
During the door cycle, if the power sliding door
module detects sufficient resistance to door travel,
such as an obstruction in the door's path, the power
sliding door module will immediately stop door move-
ment and reverse door travel to the full open or
closed position. The ability for the power sliding door
module to detect resistance to door travel is accom-
plished by hall effect sensors detecting the door
motor speed.
The power sliding door control module has the abil-
ity to learn. Anytime a door is opened or closed using
the power sliding door system the module learns
from its cycle. If a replacement power sliding door
component is installed or a door adjustment is made,
the module must re-learn the effort required to open
or close the door. A learn cycle can be performed with
a complete cycle of the door, using any one of the
command switches or with the DRB IIIt, or equiva-
lent scan tool. (Refer to 8 - ELECTRICAL/POWER
DOORS - STANDARD PROCEDURE - LEARN
CYCLE) for detailed instructions.
The power sliding door system is designed with a
number of system inhibitors. These inhibitors are
necessary for safety and/or feasibility of the power
sliding door system. The power sliding door system
inhibitors are:
²The power sliding door must be in thefullopen
or closed position in order for the power sliding door
system to start a cycle. If the door is not in this posi-
tion (based on the input from the full open, pawl or
ratchet switches) the door control module will not
respond to command switch inputs.
²The transmission must be inpark or neutral
in order for the power sliding door system to start a
cycle.
²The child lockout switch must be in the
ªUNLOCKEDº position in order for the power sliding
door systems B-pillar switches to function.
