ors CHRYSLER CARAVAN 2005 Service Manual

²If multiple obstacles are detected during the
same power open or close cycle the power sliding
door may go into full manual mode.
²If severe Diagnostic Trouble Codes (DTC) are
stored in the power sliding door control module the
power sliding door may go into full manual mode.
²Due to the high pressure created in the passen-
ger compartment with the blower motor on high, the
power sliding door may not complete a power close
cycle unless a window is cracked, allowing the pres-
sure to escape. This situation will only be experi-
enced on some vehicles, or vehicles with brand new
side door weather seals installed.
²The fuel tank filler door must be in the closed
position. Due to the sliding door interference with
the open fuel tank filler door, a mechanical linkage
prevents the side door from opening and striking the
fuel door. Refer to the Body section of this manual for
detailed information on the fuel door lockout feature.

DIAGNOSIS AND TESTING
POWER SLIDING DOOR SYSTEM
The power sliding door system contains many com-
ponents and modules. In order to obtain conclusive
testing, the Programmable Communications Interface
(PCI) data bus network and all of the electronic mod-
ules 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.

STANDARD PROCEDURE
POWER SLIDING DOOR LEARN CYCLE
Any time a power sliding 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
sliding 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. To per-
form a power sliding door learn cycle do the following:
(1)Obtain a DRB IIIt, or equivalent scan tool.
Connect the scan tool to the vehicle and check for
any power sliding door system stored diagnostic trou-
ble 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 IIIt, or equivalent scan tool is not available, the
learn cycle can be performed by opening and closing
the power sliding door using any of the normal open/
close command switches. Be certain to cycle the
power sliding door through a complete openand
close cycle or the procedure will not be complete.
(2) Using the scan tool, 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 sliding door will not complete a
full cycle, a problem exists with the power sliding door
system. (Refer to 8 - ELECTRICAL/POWER DOORS -
DIAGNOSIS AND TESTING) for additional information.
PUSH-PIN GROMMET REPLACEMENT
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 vibra-
tions to a minimum. If a push-pin grommet showssigns of wear, it must be replaced. Follow the proce-
dure 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. 2).
(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).

POWER 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.
(Refer to 23 - BODY/DOORS - SLIDING/SLIDING
DOOR - ADJUSTMENTS) for detailed instructions.
LATCH
DESCRIPTION
One power latch is used for each power sliding door.
The latch is located on the trailing edge of the sliding
door assembly (Fig. 3). This power latch assembly is com-
prised of many different components which have the abil-
ity to perform the power cinch, release, lock, unlock and
safety related operations. These components are the door
latch, lock/unlock actuator, cinch/release actuator and
child lockout, pawl, ratchet and handle switches. The
pawl and ratchet switches are used to indicate the pri-
mary and secondary latched positions. The cinch latch
also provides a connection point for the interior handle,exterior handle and hold open latch cables. If any of the
components of the latch assembly are inoperative the
complete power latch assembly must be replaced.
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 actua-
tor 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 power sliding
door has reached its secondary latch position (deter-
mined by pawl and ratchet switches). During a power
open cycle, the power release actuator will stop once the
sliding door has moved from the primary latch position.
The power latch uses inputs from the lock/unlock
actuator, power sliding door control module and child
lockout, pawl, ratchet and handle switches to provide
safe power cinch and release operations. (Refer to 8 -
ELECTRICAL/POWER DOORS - OPERATION) for
additional information.
REMOVAL
(1)Disconnect and isolate the battery negative cable.
(2) Remove the appropriate side door trim panel,
(Refer to 23 - BODY/DOORS - SLIDING/TRIM

SLIDING DOOR MOTOR
DESCRIPTION
The door motor is located in the center of the
power sliding door (Fig. 8) 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 posi-
tion 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.
OPERATION
With the push of a power sliding door command
switch, the power sliding door control module will
signal the latch assembly to release the door from its
primary locked position. The door motor will then
take over to provide the power to open the door to its
full open or closed position. The gear reduction por-
tion 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 thedoor under power and disengages it so the door can
be moved easily under manual operation.
REMOVAL
(1) Disconnect and isolate the battery negative
cable.
(2) Remove the door trim panel from the appropri-
ate door, (Refer to 23 - BODY/DOORS - SLIDING/

FULL OPEN SWITCH
DESCRIPTION
The full open switch is located in the hold open
latch (Fig. 10) under the sliding door lower hinge.
When the power sliding door control 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 indi-
cates 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 is inoperative, 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.
B-PILLAR SWITCH
DESCRIPTION
The B-pillar switches are located on the interior of
the vehicle, on the B-pillar trim panels. These
switches serve as an open and close command switch
for the appropriate power sliding door.
OPERATION
When the B-pillar switch is depressed a signal is
sent to the Body Control Module (BCM), this signal
is then sent to the power sliding door control module,
telling it to start a power open or close cycle. The
child lockout feature must be disabled and the slid-
ing door must be unlocked in order for the B-pillar
switch to function.
REMOVAL
(1) Disconnect and isolate the battery negative
cable.
(2) Using a trim stick (special tool # C-4755) or
equivalent, gently pry the leading upper edge of the
B-pillar switch away from the B-pillar trim.
