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
(1) Disconnect and isolate the negative battery
cable.
(2) Remove the rear light bar assembly from the
vehicle. Refer to Body for the procedure.
(3) Using your hands, grasp the light bar at its
sides next to thermistor/chime assembly and gently
pull the two sides of the light bar apart until the
thermistor/chime assembly can be removed.
INSTALLATION
(1) Gently pull the two sides of the light bar apart
until the thermistor/chime assembly can be installed.
(2) Install the rear light bar assembly on the vehi-
cle. Refer to the Body section of the service manual
for the procedure.
(3) Connect the negative battery cable.

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.

DIAGNOSIS AND TESTING - POWER SLIDING
DOOR SYSTEM
The power opening and closing power sliding door
system is a complex system containing many compo-
nents and modules. In order to obtain conclusive
testing, the Programmable Communications Interface
(J1850) data bus network and all of the electronic
modules that provide inputs to, or receive outputs
from the power sliding door system must be checked.
The power sliding door system was designed to be
diagnosed with an appropriate diagnostic scan tool,
such as the DRB IIIt. The most reliable, efficient,
and accurate means to diagnose the power sliding
door system requires the use of a DRB IIItscan tool
and the proper Body Diagnostic Procedures manual.
The DRB IIItcan be used to observe various switch
statuses throughout the power sliding door system to
help the technician diagnose a defective switch or
component. The DRB IIItcan also be used to actuate
various components throughout the power sliding
door system to help the technician diagnose a defec-
tive component.
Before any testing of the power sliding door system
is attempted, the battery should be fully charged, all
built-in power sliding door system inhibitors read
and understood (Refer to 8 - ELECTRICAL/POWER
DOORS - OPERATION) and all wire harness and
ground connections inspected around the affected
areas on the vehicle.
The following are quick reference diagnostic tables
to help when diagnosing and testing the power slid-
ing door system.

LATCH
DESCRIPTION
Vehicles equipped with a power side door or doors
utilize a power latch. One power latch is used for
each power door. The latch is located on the trailing
edge of the side door assembly (Fig. 5). This power
latch assembly is comprised of many different compo-
nents which have the ability to perform the power
cinch, release, lock, unlock and safety related opera-
tions. These components are the door latch, lock/un-
lock actuator, cinch/release actuator and child
lockout, pawl, ratchet and handle switches. The
ratchet switch is used to indicate the primary locked
position. The pawl switch is used to indicate the sec-
ondary position. The cinch latch also provides a con-
nection point for the interior handle, exterior handle
and hold open latch cables.
The power latch is a replaceable component. Con-
sult your Mopar parts catalog for specific part num-
bers.
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 actuator 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 side door has reached its secondary latchposition (determined by pawl and ratchet switches).
During a power open cycle, the power release actua-
tor will stop once the side door has moved from pri-
mary latch position (determined by ratchet switch).
The power latch uses inputs from the lock/unlock
actuator, power side door control module and child
lockout, pawl, ratchet and handle switches to provide
safe power cinch and release operations. Refer to
Power Side Door Operation for additional informa-
tion.
REMOVAL
(1) Disconnect and isolate the negative battery
cable.
(2) Remove the appropriate side door trim panel.
Refer to the Body section for the procedure.
(3) Remove the weather shield if necessary. Refer
to the Body section for the procedure.
(4) Open the side door all the way and remove the
door latch retaining bolts (Fig. 6).
(5) Partially close the door and pull the latch
assembly out of the side door inner panel.
(6) Disconnect all electrical connectors leading to
the latch assembly.
(7) Disconnect the inside and outside handle cables
from the latch assembly. Refer to the Body Section of
the service manual for the procedure.

(9) Connect the negative battery cable.
SLIDING DOOR MOTOR
DESCRIPTION
Vehicles equipped with a power sliding door utilize
a door motor assembly. The door motor is located in
the center of the side door (Fig. 7) 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 position to full closed/open position, after
the power latching mechanism has released.
Special wellnuts and screws are used in the side
door inner panel to retain the door motor to the door
panel. Refer to Standard Procedures in this section
for additional wellnut information.The door motor is replaced as a complete assembly,
which includes the DC motor, gear reduction and
clutch assemblies. Consult your Mopar parts catalog
for specific part numbers.
OPERATION
With the push of a Power Side Door (PSD) com-
mand switch, the PSD control module will signal the
latch assembly to release the door from its primary
locked position. The drive motor will then take over
to provide the power to open the door to its full open
or closed position. The gear reduction portion 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 the door under
power and disengages it so the door can be moved
easily under manual operation.
