LATCH
DESCRIPTION
Vehicles equipped with a power liftgate, utilize a
power cinch/release latch. This 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 RS
models, this latch is designed to perform a power
release only. The power cinch and release capability
is accomplished by an actuator mounted to the lead-
ing edge of the latch assembly. The latch is located in
the lower center of the liftgate assembly (Fig. 12) and
contains integral pawl and ratchet switches. The
ratchet switch acts as a liftgate ajar switch.
The power latch assembly can be serviced as a
complete assembly, latch without actuator or just the
actuator. Consult your Mopar parts catalog for spe-
cific part numbers.
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.

LATCH ACTUATOR
DESCRIPTION
Vehicles equipped with a power liftgate utilize a
power cinch latch or power release latch (Fig. 13).
The power cinch and/or power release is made possi-
ble by a latch actuator attached to the leading edge
of the power latch assembly. This 12 volt latch actua-
tor contains a small drive gear that meshes with the
latch assemblies internal gears to perform the power
cinch close / power release operations. Refer to the
Latch assembly for more information.
The power cinch/release actuator is serviceable
component. Consult your MoparŸ parts catalog for
specific part numbers.
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.

EXTERIOR HANDLE SWITCH
DESCRIPTION
Vehicles equipped with a power liftgate or power
locks utilize a exterior handle switch. The exterior
handle switch is a electronic release switch mounted
to the rear license plate lamp housing assembly,
located just above the license plate. This switch con-
trols the power liftgate release function and is also
capable of reversing the power liftgate when it is in
motion. A full power open cycle cannot be performed
using this switch, only one of the power open com-
mand switches (key fob and overhead console
mounted) can be used to perform a full power open
cycle.
The exterior handle switch is a serviceable compo-
nent. Consult your MoparŸ parts catalog for a spe-
cific part number.
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 Body Con-
trol Module then sends a signal to the power liftgate
control module via the J1850 PCI data bus circuit.
The power liftgate control module then sends a sig-
nal 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 negative battery
cable.
(2) Open the liftgate and remove the liftgate trim
panel. Refer to the Body section of the service man-
ual for the procedure.

CHIME/THERMISTOR
DESCRIPTION
Vehicles equipped with a power liftgate utilize a
chime/thermistor assembly. The chime/thermistor
assembly is a small capacitor shaped electrical com-
ponent mounted to the rear license plate lamp hous-
ing assembly (Fig. 15), located just above the license
plate. The chime portion of the assembly controls the
audible chime sound heard at the rear of the vehicle
when the power liftgate is in motion. The thermistor
portion of the assembly is a temperature sensor, used
by the power liftgate module.
The chime/thermistor assembly is a serviceable
component. Consult your MoparŸ parts catalog for a
specific part number.
OPERATION
The chime/thermistor assembly performs two dif-
ferent functions for the power liftgate system. First,
the chime portion provides an audible chime sound
which is controlled by the power liftgate module. The
chime/thermistor assembly is hardwired to the power
liftgate module. Second the thermistor provides a
outside temperature reading by way of a resistance
reading (V- ohms) supplied to the power liftgate
module. As temperature increases the resistance
reading (V- ohms) increases, as temperature
decreases the resistance reading (V- ohms)
decreases.
REMOVAL

POWER SLIDING DOOR
SYSTEM
DESCRIPTION
Some vehicles are equipped with a power opening
and closing sliding door system (Fig. 1). Depending
on how the vehicle is ordered it may be equipped
with only a right side power door or right and left
side power doors. This power sliding door system is a
complex system consisting of many components.
Some of these components are the door motor, latch
assembly, sliding door control module, lower drive
unit, flex drive assembly, wire harness and track,
lower drive unit track and rack assembly, full open
switch, B-pillar switch, overhead console switch, key
fob switches (Fig. 2), pawl switch, ratchet switch and
child lockout and handle switches.
Each power side door has its own door control mod-
ule, 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 side 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 side 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 side 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 side
door latch assembly. The B-pillar switch, as it will be
referred to, is an open and close command switch
located on the vehicles interior body side B-pillar
trim. The overhead console switch, is an open and
close command switch located in the vehicle's over-
head console. More detailed information can be found
on these components later in this section.

Safety is of the utmost concern with the power
sliding door system. Software technology has enabled
the power sliding door control module to detect resis-
tance 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 Intelligent Power Module
(IPM) assembly (Fig. 3). The child lockout switch pre-
vents 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 J1850 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 diagnose these trouble codes. Refer to the
Body Diagnostic Manual for a complete list of diag-
nostic routines.
