POWER LIFTGATE SYSTEM
DESCRIPTION
the components of the power liftgate system are:
²Liftgate gear motor assembly
²Latch assembly
²Lift gear and rod
²Power liftgate control module
²Chime/thermistor
²Full open switch
²Engage actuator
²Pinch sensor
²Liftgate handle switch
²Overhead console switch
²Key fob switches (Fig. 1)
²Pawl switch
²Ratchet switch
The power liftgate system has its own power lift-
gate control module, located on the vehicles left body
D-pillar behind the trim panel. The power liftgate
gear motor assembly is located just above the control
module. The latch assembly is located in the bottom
center of the power liftgate, below the exterior lift-
gate handle switch. The power liftgate full open
switch, engage actuator, lift gear and rod are part of
the liftgate gear motor assembly. The pawl and
ratchet switches are part of the latch assembly. The
pinch sensors are located along the right and left
sides of the power liftgate, just above the body line.The liftgate handle switch is a power release switch
and is located in the rear light bar assembly, just
above the license plate. The overhead console switch
is a power open and close command switch located in
the vehicles overhead console.
Software technology has enabled the power liftgate
control module to detect resistance to liftgate travel,
which allows the power liftgate to stop and reverse
direction anytime an obstruction is felt or any of the
command switches are operated (only in closing
direction). Battery voltage is supplied to the power
liftgate system through a 40 amp fuse, located in the
Integrated Power Module (IPM) assembly. If the
power liftgate system develops a fault, the power lift-
gate can still be operated manually with a key, sim-
ilar to a manual liftgate.
The power liftgate control module communicates
on the Programmable Communication Interface (PCI)
Bus Circuit. Therefore, the power liftgate control
module can generate and store its own Diagnostic
Trouble Codes (DTC). The vehicles Body Control
Module (BCM) receives and supplies messages to the
power liftgate control module via the PCI bus circuit.
A diagnostic scan tool, such as the DRB IIItor equiv-
alent, is used to read and troubleshoot these DTCs.
Refer to the Body Diagnostic 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
schematic or connector pin-out information.
WARNING: BE CERTAIN TO READ ALL WARNINGS
AND CAUTIONS BEFORE ATTEMPTING ANY SER-
VICE OF THE POWER LIFTGATE SYSTEM OR COM-
PONENTS.
OPERATION
With the push of a power liftgate open/close com-
mand switch (key fob or overhead console mounted) a
signal is sent out on the Programmable Communica-
tion Interface (PCI) Data Bus circuit. This signal is
detected at the Body Control Module (BCM). The
BCM then sends a signal out on the PCI Data Bus
circuit to the power liftgate control module. The
power liftgate control module then signals the power
liftgate motor to start an open or close cycle, depend-
ing on what position the liftgate is in.
During a liftgate open or close cycle, if the power
liftgate module detects sufficient resistance to liftgate
travel, such as an obstruction in the path of the lift-
gate, the power liftgate control module will immedi-
ately stop the liftgate movement and reverse travel
to the full open or closed position. The ability for the
power liftgate module to detect resistance to liftgate

EXTERIOR HANDLE SWITCH
DESCRIPTION
The exterior handle switch is an electronic release
switch mounted to the rear license plate lamp hous-
ing assembly, located just above the license plate.
This switch controls the power liftgate release func-
tion and is also capable of reversing the power lift-
gate when it is in motion. A full power open cycle
cannot be performed using this switch, only one of
the power open command switches (key fob and over-
head console mounted) can be used to perform a full
power open cycle. The exterior handle switch is a ser-
viceable component.
OPERATION
When the exterior handle switch is depressed, with
the liftgate in the closed position, a message is sent
to the Body Control Module (BCM). The BCM then
sends a signal to the power liftgate control module
via the Programmable Communication Interface
(PCI) data bus circuit. The power liftgate control
module then sends a signal to the power latch
mounted actuator, which moves the liftgate from the
primary closed and latched position to the open and
movable position. If the liftgate is not pulled open
once the latch releases within a few seconds, the
latch will cinch closed again.
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) Remove the rear lamp bar assembly from the
vehicle.(4) Locate the two wires going to the exterior han-
dle switch. Cut the tie strap and trace the wires to
the large electrical connector and back the wires out
of the large connector and through the grommet.
Take care to mark the location of the wire ter-
minals in relation to the large connector so
that they are positioned in the appropriate cav-
ities upon switch installation.
(5) Depress the two exterior handle switch retain-
ing tabs and roll the switch out of the light bar
assembly (Fig. 5).
INSTALLATION
(1) Install the handle switch in the light bar
assembly (Fig. 6).
(2) Locate the two wires going to the exterior han-
dle switch. Install the wires through the grommet
and in the large connector. Secure with a tie strap.
NOTE: Be certain wires are reinstalled in the correct
wire cavities. Failure to do so could result in dam-
age to the handle switch. Refer to the appropriate
wiring information for complete circuit schematic or
connector pin-out information.
(3) Install the rear light bar.
(4) Install the liftgate trim panel, (Refer to 23 -
BODY/DECKLID/HATCH/LIFTGATE/TAILGATE/
TRIM PANEL - INSTALLATION).
(5) Connect the battery negative cable.

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.
(6) Remove the power latch from the vehicle.

TRIM PANEL - INSTALLATION).
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
