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 pawl
and ratchet switches are used to indicate the primaryand secondary latched positions. The cinch latch also
provides a connection 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 latch
position (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.
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.

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 thepower and torque to move the sliding door from the
open/closed position 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. 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.
REMOVAL
(1) Disconnect and isolate the negative battery
cable.

FULL OPEN SWITCH
DESCRIPTION
Vehicles equipped with a power sliding door utilize
a full open switch. This switch is located in the hold
open latch (Fig. 9) under the side door lower hinge.
When the power side door 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 indicates 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 proves faulty, 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.

DESCRIPTION
POWER DOOR LOCK SYSTEM
The front doors, sliding door(s) and liftgate are
equipped with actuator motors to lock or unlock the
latch mechanisms. The door lock actuator motor is
not serviced separately from the door latch, except
for the sliding door(s).
AUTOMATIC DOOR LOCK
The vehicle comes with two options for power door
locks:
²Rolling automatic lock (ENABLE), doors auto-
matically lock at approximately at 25.7 Km/h (16
mph).
²No rolling automatic lock (DISABLE), doors do
not automatically lock when the vehicle is moving.
AUTOMATIC DOOR UNLOCK
The doors will unlock automatically on vehicles
equipped with power door locks if:
²Auto door locks feature is enabled and automatic
unlock is enabled.²The transmission was in gear and speed was
above zero.
²The transmission in park or neutral and speed
is zero.
²Any door (excluding liftgate) opens.
DOOR LOCK INHIBIT
The BCM cancels out the door lock switch actua-
tion, when the key is in the Ignition Switch and
either front door is open.
Pressing the key fob RKE lock/unlock under these
conditions results in normal lock/unlock activation.
CENTRAL LOCKING
If equipped with Vehicle Theft Security System
(VTSS), all the doors can be locked with the key by
using the driver door lock cylinder. Turning the key
to the lock position will lock all the doors.
DOOR LOCK CIRCUIT PROTECTION
The door lock system is protected by a 40 amp fuse
located in the IPM. The BCM receives lock/unlock
input and will turn on the appropriate drivers and
provide a voltage level to the door lock motor for a
specific time. The IPM is located along the side of the
vehicle battery in the engine compartment.
8N - 38 POWER LOCKSRS

REMOTE KEYLESS ENTRY SYSTEM
The key fob transmitter (Fig. 1) has six buttons.
Three of them, LOCK, UNLOCK, and PANIC, are
used to actuate parts of, and program the Remote
Keyless Entry (RKE) system via the customer pro-
gramming mode. It is not necessary to use the
PANIC button with the DRB IIItscan tool mode of
programming.
OPERATION
POWER DOOR LOCK SYSTEM
The Body Control Module (BCM) locks or unlocks
the doors when an actuation input signal from a door
lock switch or Remote Keyless Entry Module (RKE)
is received. The BCM turns on the output drivers
and provides a voltage level to the door lock motor
for a specified time. The BCM locks the doors auto-
matically when the vehicle is driven beyond the
speed of 25.7 Km/h (16 mph). The rolling door lock
feature can be disabled if desired. All doors and lift-
gate can be locked or unlocked using mechanical but-
ton or key cylinder methods (Liftgate cylinder does
not lock/unlock vehicle. It only unlocks the liftgate).
AUTOMATIC DOOR LOCKS
The BCM is equipped with a disable feature to
stop the speed sensitive automatic door locks from
functioning. The DISABLE feature can be switchedON or OFF as desired. When the system is DIS-
ABLED the door locks will operate normally, but will
not lock automatically when the vehicle is rolling.
When the door locks are ENABLED the door locks
will automatically lock when the vehicle is moving at
about 25.7 Km/h (16 mph). All doors are closed, the
PCM has set the ªOK TO LOCKº bit, and doors were
not previously locked.
DOOR LOCK INHIBIT
If the key is in the ignition, in any position, and
either front door is ajar, all power door lock function-
ing shall be disabled when activating either door lock
switch. Also, if the Vehicle Theft Alarm (VTA) is
armed, the door lock switch ªUNLOCKº feature will
be disabled until the vehicle is disarmed. Pressing
the RKE lock/unlock button under these conditions
will result in a normal lock/unlock activation.
After the key is removed from the Ignition Switch,
or the doors are closed, the power door locks will
operate normally.
CENTRAL LOCKING
If equipped with Vehicle Theft Security System
(VTSS), all the doors can be locked with the key by
using any of the door lock cylinders. Turning the key
to the LOCK position will lock all the doors.
When the driver door key cylinder switch is
detected active, the BCM will activate the illumi-
nated entry feature and the individual front doors
will become mechanically unlocked. To central unlock
all doors, a second transition from OFF to UNLOCK
has to occur within 2 seconds of the first complete
UNLOCK cycle.
To central unlock the driver door, turn the key to
the rear of the vehicle. This indicates an unlock sig-
nal to the BCM. When key cylinder switch is
detected as active, the BCM will activate the illumi-
nated entry feature. The individual doors will become
mechanically unlocked.
To central lock the vehicle, the driver door lock cyl-
inder is turned toward the front of the vehicle. When
a lock input from either key cylinder is detected as
active, the BCM will cancel the illuminated entry
feature and perform the central lock operation.
DOOR LOCK CIRCUIT PROTECTION
The BCM controls the door lock output drivers. If
the door lock switch is actuated continuously for
more than one second the BCM will turn the output
driver OFF (the BCM would consider the switch
stuck). The lock motors are protected with Positive
Temperature Coefficient (PTC) device that prevents
motor burn out.

The Remote Keyless Entry Module is capable of
retaining the transmitter Vehicle Access Code(s)
(VAC) in its memory even after vehicle power has
been interrupted.
NOTE: Additional features available to the customer
are described in the Vehicle Owners Manual.
The RKE system activates the optional memory
seat, mirror system and adjustable pedals, if
equipped. Two primary key fob transmitters can be
programmed to actuate memory seat and mirror set-
ting 1 or 2. Two additional key fob transmitters can
be added, but they will not be able to operate the

TION).
DOOR CYLINDER LOCK
SWITCH
DESCRIPTION
The Door Cylinder Lock Switch 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.
