SLIDING DOOR MODULE
DESCRIPTION
Vehicles equipped with a power sliding door utilize
a sliding door control module. The sliding door con-
trol module is located behind the sliding door trim
panel in the center of the door, just above the sliding
door motor (Fig. 22). This module controls the opera-
tion of the door through the Programmable Commu-
nication Interface (PCI) J1850 data bus circuit and
the Body Control Module. The sliding door control
module contains software technology which enables it
to detect resistance to door travel and to reverse door
travel in order to avoid damage to the door or to
avoid possible personal injury if the obstruction is a
person. This feature functions in both the opening
and closing cycles. If the power sliding door system
develops any problems the control module will store
and recall Diagnostic Trouble Codes (DTC). The use
of a diagnostic scan tool, such as the DRB IIItis
required to read and troubleshoot these trouble
codes. The sliding door control module can be
reflashed if necessary. Refer to the latest Technical
Service Bulletin (TSB) Information for any updates.
The power door control module is a replaceable
component and cannot be repaired, if found to be
faulty it must be replaced. Consult your MoparŸ
parts catalog for a specific part number.OPERATION
The power sliding door control module serves as
the main computer for the power sliding side door
system. All power door functions are processed
through the power door control module and/or the
vehicles body control module (BCM). At the start of a
power open command, a signal is sent to the BCM
and then to the power door control module via the
J1850 data bus circuit. This signal, generated by any
of the power door command switches, tells the power
door control module to activate a power latch release,
engage the clutch assembly and drive the door into
the full open position. If an obstacle is felt during
this power open cycle, the module will reverse direc-
tion and close the door. This process is also enabled
during a power close cycle. This process will repeat
three times, and if a fourth obstacle is detected, the
door will go into full manual mode. Once the full
open position is obtained, a hold open latch assembly
mounted full open switch tells the control module
that the door has reached the full open position. If
the power sliding door system develops any problems
the control module will store and recall Diagnostic
Trouble Codes (DTC). The use of a diagnostic scan
tool, such as the DRB IIItis required to read and
troubleshoot these trouble codes.

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 is 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 any of the door lock cylinders. 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.

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 switched
ON 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 either of the front key cylinder switches 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. For the passenger door, turn the key
toward the front of the vehicle. When either key cyl-
inder switch is detected as active, the BCM will acti-
vate the illuminated 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. The
passenger door lock cylinder is turned toward the
rear of the vehicle. When a lock input from either
key cylinder is detected as active, the BCM will can-
cel the illuminated entry feature and perform the
central lock operation.

opens/closes the liftgate remotely, if equipped.If not
equipped with power liftgate, pressing the liftgate but-
ton will allow a one time 30 second access to liftgate.
²PANIC: Pressing the PANIC button sounds the
horns at half second intervals, flashes the exterior
lamps, and turns ON the interior lamps. The panic
alarm will remain on for three minutes, or until the
PANIC button is actuated again or the ignition
switch is turned to the RUN position.
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 mem-
ory seat and mirror system (Refer to 8 - ELECTRI-
CAL/POWER SEATS - OPERATION) and (Refer to 8 -
ELECTRICAL/POWER MIRRORS - OPERATION).
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 and passenger door lock cylinders.
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 cylinder 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, via
the Programmable Communication Interface (PCI)
bus.
If turning the key cylinder once, toward the front
of the vehicle (for either driver or passenger doors),
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 (either passenger or driver doors) 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. Furthermore,
this will arm the vehicle theft security system and
turn off the illuminated entry.
DIAGNOSIS AND TESTING - DOOR CYLINDER
LOCK SWITCH
(1) Visually inspect the switch for proper installa-
tion. Make sure it is seated on the rear of the key
cylinder, with the tab of the door key cylinder prop-
erly aligned with the slot on the door cylinder lock
switch.
(2) Disconnect the switch at the harness connector
and check the resistance in each switch position.

DOOR LOCK MOTOR
DIAGNOSIS AND TESTING - DOOR LOCK
MOTOR
Verify battery condition before testing door lock
motor(s) (Refer to 8 - ELECTRICAL/BATTERY SYS-
TEM/BATTERY - DIAGNOSIS AND TESTING).
To determine which motor is faulty, check each
individual door for electrical lock and unlock or dis-
connect the motor connectors one at a time, while
operating the door lock switch. In the event that
none of the motors work, the problem may be caused
by a shorted motor or a bad switch. Disconnecting
the defective motor will allow the others to work.To test an individual door lock motor, disconnect
the electrical connector from the motor. To lock the
door, connect a 12 volt power source to the positive
pin of the lock motor and a ground wire to the other
pin. Refer to the appropriate wiring information. The
wiring information includes wiring diagrams, proper
wire and connector repair procedures, further details
on wire harness routing and retention, as well as
pin-out and location views for the various wire har-
ness connectors, splices and grounds. To unlock the
door reverse the wire connections at the motor pin
terminals. If these results are NOT obtained, replace
the motor.
