STANDARD PROCEDURE
STANDARD PROCEDURE - POWER DOOR
LEARN CYCLE
Any time a power side door component is removed,
replaced, door adjustment is performed or diagnostic
trouble codes are addressed and erased, a learn cycle
mustbe performed. This learn cycle enables the
power side door control module to learn or relearn its
critical information (travel limits, resistance to door
travel, etc.) which allows it to perform properly and
safely. It also tells the technician that the system is
performing properly and is able to be returned to ser-
vice. To perform a power door learn cycle do the fol-
lowing:
(1) Obtain a DRB IIItscan tool.
Connect the DRB IIItto the vehicle and check for
any power side door system stored diagnostic trouble
codes, erase any stored codes. Operate the system
and check to see if any trouble codes return. If any
diagnostic trouble codes return, diagnose, correct and
erase the codes before performing the learn cycle. If a
DRB IIItscan tool is not available, the learn cycle
can be performed by opening and closing the power
side door using any of the normal open/close com-
mand switches. Be certain to cycle the side door
through a complete openandclose cycle or the pro-
cedure will not be complete.
(2) Using the DRB IIIt, Go into Test Routine
Menu and select a power open command.
(3) Select a power close command.
(4) The power side door learn cycle is complete.
NOTE: If the power side door will not complete a
full cycle, a problem exists with the power side
door system. Refer to Power Side Door Diagnosis
and Testing.
STANDARD PROCEDURE - PUSH-PIN
GROMMET REPLACEMENT
Vehicles equipped with a power sliding door utilize
push-pin grommets. These push-pin grommets are
used to hold and isolate the power sliding door motor
to and from the door inner panel. This secures the
door motor assembly to the inner panel and keeps
the audible motor vibrations to a minimum. If a
push-pin grommet shows signs of wear, it must be
replaced. Follow the procedure below if replacement
is necessary.
(1) Remove the door motor from the door inner
panel. (Refer to 8 - ELECTRICAL/POWER DOORS/
MOTOR - REMOVAL).(2) Using a trim panel tool (special tool #C-4755)
or equivalent, remove the push-pin grommets from
the inner panel by pulling them straight out (Fig. 4).
(3) Install the replacement push-pin grommets in
the inner panel and install the door motor(Refer to 8
- ELECTRICAL/POWER DOORS/MOTOR - INSTAL-
LATION).
STANDARD PROCEDURE - SLIDING DOOR
ADJUSTMENT
In order for the power sliding door system to func-
tion properly the door must move freely and
smoothly. The power sliding door system can accom-
modate for some minor changes in the effort required
to move the door. However, in extreme conditions the
door may need to be mechanically adjusted for proper
fit. (Refer to 23 - BODY/DOORS - SLIDING/SLID-
ING DOOR - ADJUSTMENTS).
If a problem exists with the power sliding door and
it is suspected to be extreme effort, check for proper
door alignment and adjustment first, then check the
door tracks and drive unit for free manual operation.
Use a known good vehicle for side door comparison
data. Refer to the Side Door Adjustment procedure in
the Body section of the service manual for detailed
instructions.

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.
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.

LOWER DRIVE UNIT TRACK &
RACK
DESCRIPTION
Vehicles equipped with a power sliding side door
utilize a lower drive unit track or door track and
rack assembly. This track provides a mating rack
gear (Fig. 13) for the lower drive unit to engage. The
track also accepts the lower hinge rollers, which
helps support the weight of the side door as well as
providing a smooth surface for the hinge rollers to
move upon.
The lower door track is a replaceable component.
Consult your Mopar parts catalog for specific part
numbers.
OPERATION
With the start of a power door open cycle, the door
motor drives the flex drive assembly. The flex drive
assembly drives the lower drive unit. A metal drive
gear which is part of the lower drive unit, meshes
with the door track rack teeth and moves the door
into the full open position. The same operation
repeats itself, during a power close cycle only the sys-
tem rotates in the opposite direction.
REMOVAL
(1) Disconnect and isolate the negative battery
cable.

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.

POWER MIRRORS
DESCRIPTION
If equipped with power mirrors, the control switch
is located on the instrument panel to the left of the
headlamp switch.
OPERATION
The power mirrors are connected to battery feed at
all times. Each mirror head contains two electric
motors, two drive mechanisms, an electric heating
element, and the mirror glass. If the vehicle is
equipped with the optional memory system, the
driver side mirror head also contains both a horizon-
tal and a vertical motor position sensor. One motor
and drive controls mirror up-and-down movement,
and the other controls right-and-left movement.An optional driver side outside electrochromic mir-
ror is able to automatically change its reflectance
level. This mirror is controlled by the circuitry of the
automatic day/night inside rear view mirror. A thin
layer of electrochromic material between two pieces
of conductive glass make up the face of the mirror.
Two photocell sensors on the inside rear view mirror
are used to monitor light levels and adjust the reflec-
tance of both the inside and driver side outside mir-
rors. This change in reflectance helps to reduce the
glare of headlamps approaching the vehicle from the
rear. (Refer to 8 - ELECTRICAL/POWER MIRRORS/
AUTOMATIC DAY / NIGHT MIRROR - DESCRIP-
TION) for more information on this system.
The motors which operate the mirrors are part of
the mirror assembly and cannot be serviced sepa-
rately.

ered. This defeats the day-detect logic. If OK, go to
Step 8. If not OK, replace the faulty mirror unit.
(8) With the mirror darkened, place the transmis-
sion gear selector lever in the Reverse position. The
automatic day/night mirror should return to its nor-
mal reflectance. If not OK, replace the faulty mirror
unit.
Bench testing both mirrors can be done, of care is
exercised. For an inside mirror, the pin closest to he
mount is 12V (+), the next is 12V (-). The third is
reverse override. The fourth is outside mirror (+),
and the fifth is outside mirror (-).Do not apply 12
volts to the fourth and fifth pins.With 12 volts
on pins 1 and 2, the mirror can be tested by blocking
the rear sensor and shining a light into the forward
sensor. For an outside mirror, there is a 2±pin con-
nector. Applying 1.2 volts will cause the mirror to
dim. If the mirror does not dim, the entire glass
assembly can be replaced just as it is when the glass
is broken.
WARNING: Do not apply 12 volts to the outside mir-
ror. Damage to the mirror will result.
POWER FOLDAWAY MIRROR
SWITCH - EXPORT
DESCRIPTION
These vehicles may be equipped with Power Fold-
away Mirrors. This feature allows both the driver
and passenger side view mirrors to fold inward
(retract) on demand. The vehicle has an additional
switch located on the steering column that controls
the folding function of the mirror assembly (Fig. 2).
The fold-away side view mirror is attached to the
vehicle's door in the same manner as mirrors without
the fold-away option. The fold-away mirrors unique
option is the internal motor which allows the mirrors
to fold inward on demand. The fold-away mirror
motor is not serviceable separately and if a motor is
found to be faulty the entire side view mirror must
be replaced.
OPERATION
When the mirror retract switch is depressed, both
of the side view mirrors will fold inward, Thus mak-
ing the overall width of the vehicle the smallest pos-
sible. This can be helpful were parking space is a
absolute minimum.
When the driver's door is opened, only the driver's
door mirror will unfold. If the passenger door is
opened, both mirrors will unfold.
The power fold away mirror system consists of the
following components: mirror switch, side view mir-ror, relay, wires and fuse. Refer to the appropriate
wiring information. The wiring information includes
wiring diagrams, proper wire and connector repair
procedures, details of wire harness routing and
retention, connector pin-out information and location
views for the various wire harness connectors, splices
and grounds.
