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.

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.

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.
