GENERAL INFORMATION

On vehicles equipped with AutoStick, the display
includes an O/D OFF indicator that is illuminated
when the driver presses the Overdrive Off button
on the transaxle shifter.
3.11.1 INSTRUMENT CLUSTER SELF TEST
1. Depress and hold the Odometer Reset button.
2. Turn the ignition switch to the RUN/START
position.
3. Release the Odometer reset button.
The Instrument Cluster will illuminate all indi-
cators and step the gauges through several calibra-
tion points. Also, the odometer will display any
stored codes that may have set.
3.11.2 MESSAGE CENTER
The Message Center is located above the brow of
the Instrument Cluster. It houses the following
warning indicators: Check Engine/Service Engine
Soon, high beam, left and right turn signals, Secu-
rity Alarm Set, and low oil pressure. On base
models equipped with the three-speed transaxle,
these indicators appear in the face of the cluster.
The Security Alarm set indicator is a red circle.
Activation of Instrument Cluster indicators is
coordinated with indicators in the message center
and EVIC to avoid redundancy. A revised safety
standard now requires that the seat belt warning
lamp in the Instrument Cluster remain lit if the
driver seat belt is not buckled. A headlamp out ISO
indicator has been added to the Instrument Cluster
to alert the driver when a headlamp is not function-
ing.
3.12 INTERIOR LIGHTING
3.12.1 COURTESY LAMP CONTROL
The body controller has direct control over all of
the vehicle's courtesy lamps. The body computer
will illuminate the courtesy lamps under any of the
following conditions:
1. Any door ajar and courtesy lamp switch on the
headlamp switch is not in the dome off position.
2. The courtesy lamp switch on the headlamp
switch is in the dome on position.
3. A Remote Keyless Entry unlock message is re-
ceived.
4. Driver door unlocked with key (with VTSS only).
3.12.2 ILLUMINATED ENTRY
Illuminated entry will be initiated when the cus-
tomer enters the vehicle by unlocking the doors
with the key fob, or with the key if the vehicle is
equipped with vehicle theft alarm. Upon exiting thevehicle, if the lock button is pressed with a door
open, illuminated entry will cancel when the door
closes. If the doors are closed and the ignition
switch is turned on, the illuminated entry also
cancels. The illuminated entry feature will not
operate if the courtesy lamp switch is in the dome
off position.
3.12.3 INTERIOR LIGHTING BATTERY
SAVER
If any of the interior lamps are left on after the
ignition is turned off, the BCM will turn them off
after 8 minutes. To return to normal operation, the
courtesy lamps will operate after the dome lamp
switch or door ajar switch changes state. The glove
box and switched reading lamps require that the
ignition be turned to the on/acc position.
3.13 MEMORY SYSTEM
The memory system consists of power driver 's
seat, power mirrors and radio presets. The Memory
Seat/Mirror Module (MSMM) is located under the
driver 's seat. It receives input from the following:
driver 's manual 8-way seat switch, driver 's seat
position sensors, PCI bus circuits, and the power
mirror sensors. The module uses these inputs to
perform the following functions: position the driv-
er 's memory seat, both exterior mirrors (during
recalls), and send/receive the memory system infor-
mation over the PCI bus.
The Memory Set Switch is wired to the Body
Control Module (BCM). When a button (either #1 or
#2) is pressed on the set switch causes the to BCM
send a message to the MSMM which in turn sends
a motion status messages to the BCM. If the BCM
receives no motion from the MSMM it will send a
recall message to the MSMM and radio (once igni-
tion is in run or accessory). The MSMM will in turn
position the drivers seat, both mirrors along with
recalling the radio presets. If the drivers seat or
either exterior mirror is inoperative from its own
respective switches, use the service information
and schematic to diagnose the problem. This man-
ual addresses the memory problems only and it is
assumed there is not a basic component failure.
3.13.1 POWER SEAT
The memory power seat provides the driver with
2 position settings for the driver 's seat. Each power
seat motor is connected to the MSMM with two
motor drive circuits. Each circuit is switched be-
tween battery and ground. By being able to bi-
directionally drive the circuits, the MSMM controls
the movement of the motors based on input from
the power seat switch or from the position sensors
when performing a memory recall. Each motor

seconds instead of 5, the CMTC will set the
variance to 8 and enter the fast calibration
mode.
3. The VAR light will come on and the last variance
setting will be displayed.
4. Press the STEP button to set the zone number.
5. Press the US/M button and resume normal op-
eration.
NOTE: Do not attach any magnetic device
such as a magnetic CB antenna to the
vehicle. This can cause the compass to give
false readings.
3.15 POWER DOOR LOCK SYSTEM
When the BCM receives input for a lock request
from a door lock switch, RKE or cylinder lock switch
(only with VTSS), it will turn the lock driver on for
a specified time of 375 msec. If the request is there
beyond 375 msec, the BCM considers the door lock
signal stuck. Once a door lock or unlock signal is
stuck for longer than 10 seconds, the BCM will set
a trouble code and the signal input is ignored until
the stuck condition disappears. The door lock
switches provide a variable amount of resistance
thereby dropping the voltage of the multiplexed
(MUX) circuit and the BCM will respond to that
command.
3.15.1 SLIDING DOOR MEMORY LOCK
When the BCM receives an input for a lock
request and a sliding door is open, the BCM will
turn on the lock driver as described above, and will
turn it on again when all sliding doors are closed.
NOTE: If the BCM receives an unlock input before
a sliding door is closed, this will cancel the memory
lock.
3.15.2 DOOR LOCK INHIBIT
When the key is in the ignition and in any
position and either front door is open, the door lock
switches LOCK functions are disabled. The UN-
LOCK functions are still functional. This protects
against locking the vehicle with the keys still in the
ignition. The RKE key fob will still lock the doors as
usual. This allows the driver to lock the vehicle with
the engine running for warm up.
3.15.3 AUTOMATIC DOOR LOCKS
This feature can be enabled or disabled by using
either the DRBIIItor the customer programming
method. When enabled all the doors will lock when
the vehicle reaches a speed of 18 MPH (29 KMH)
and all the doors are closed. If a door is opened and
the vehicle slows to below 18 MPH (29 KMH), thedoor locks will operate again once all doors are
closed and the speed is above 15 MPH (24 KMH).
3.15.4 REMOTE KEYLESS ENTRY (RKE)
The body control module interfaces with the RKE
module via a one-way serial bus interface. The RKE
module is not on the PCI bus. The RKE module
sends a 0-5 volt pulse width signal to the BCM
depending on which button on the transmitter was
pressed. The BCM controls the door lock/unlock
functions and the arming/disarming of the Vehicle
Theft Security System (if equipped) and the activa-
tion of illuminated entry. The BCM will also send
the appropriate messages to the Power Sliding
Doors and Power Liftgate modules. The Intelligent
Power Module (IPM) activates the park lamps,
headlamps, and horn for horn chirp when sent the
appropriate message from the BCM as received
from the RKE transmitter. When a one-button
press is made for unlock, both driver side doors will
unlock and the front and rear turn signal will flash.
When a second press is initiated (within 5 seconds
of the first) both passenger doors will unlock and all
four turn signals will flash.
The RKE module is capable of retaining up to 4
individual access codes (4 transmitters). If the
PRNDL is in any position except park, the BCM will
ground the interface thereby disabling the RKE.
The 2 button transmitter will have 2-CR2016
batteries in series. The 5 button transmitter will
have 1-CR2016 battery. The minimum battery life
should be approximately 4.7 years based on 20
transmissions a day at 84ÉF (25ÉC). Using the
DRBIIItand selecting RKE FOB Test can test the
transmitter.
The RKE module can be programmed via the
DRBIIItor the customer programming method.
The BCM will only allow programming mode to be
entered when the ignition is in the on position, the
PRNDL is in park position, and the VTSS (if
equipped) is in the disarmed mode.
3.16 POWER FOLDING MIRRORS
The power folding mirrors are powered to two
positions: folded and unfolded. The driver may
choose fold or unfold with a switch that is located on
the right side of the steering column. The folding
mirror switch grounds a sense wire that comes from
the Body Control Module when it is placed in the
fold position. The mirrors will move to the position
designated by the switch whether the ignition
switch is the On or Off position and both front doors
are closed. When the Power Folding Mirror switch
is left in the fold position during a vehicle exit the
mirrors will automatically unfold then refold after
both front doors are closed. This is to prevent mirror
contact with either front door when opened. When

GENERAL INFORMATION

POWER LIFTGATE SYSTEM
DESCRIPTION
Some vehicles are equipped with an automatic
opening and closing power liftgate system (Fig. 1).
This power liftgate system is a complex system con-
sisting of many components. Some of these compo-
nents are the liftgate gear motor assembly, latch
assembly, lift gear and rod, liftgate control module,
chime/thermistor, full open switch, engage actuator,
pinch sensor, liftgate handle switch, overhead console
switch, key fob switches (Fig. 2), pawl switch and
ratchet switch.
The power liftgate system has its own door control
module, located on the vehicles left body D-pillar
behind the trim panel. (Refer to 8 - ELECTRICAL/
ELECTRONIC CONTROL MODULES/DOOR CON-
TROL MODULE - DESCRIPTION) The power
liftgate gear motor assembly is located just above the
control module. The latch assembly is located in the
bottom center of the power liftgate, below the exte-
rior liftgate handle switch. The power liftgate full
open switch, engage actuator, lift gear and rod are
part of the liftgate gear motor assembly. The pawland ratchet switches are part of the latch assembly.
The pinch sensor or sensors are located along the
right and left sides of the power liftgate, just above
the body line. The liftgate handle switch is an power
release switch and is located in the rear light bar
assembly, just above the license plate. The overhead
console switch is an power open and close command
switch located in the vehicles overhead console.
Safety is of the utmost concern with the power lift-
gate system. Software technology has enabled the
power liftgate control module to detect resistance to
liftgate travel, which allows the power liftgate to stop
and reverse direction anytime an obstruction is felt
or any of the command switches are operated (only in
closing direction). Battery voltage is supplied to the
power liftgate system through a 40 amp fuse, located
in the Intelligent Power Module (IPM) assembly (Fig.
3). In the unlikely event that the power liftgate sys-
tem develops a fault the power liftgate can still be
operated manually with a key, just like a standard
manual liftgate.

EXTERIOR HANDLE SWITCH
DESCRIPTION
Vehicles equipped with a power liftgate or power
locks utilize a exterior handle switch. The exterior
handle switch is a electronic release switch mounted
to the rear license plate lamp housing assembly,
located just above the license plate. This switch con-
trols the power liftgate release function and is also
capable of reversing the power liftgate when it is in
motion. A full power open cycle cannot be performed
using this switch, only one of the power open com-
mand switches (key fob and overhead console
mounted) can be used to perform a full power open
cycle.
The exterior handle switch is a serviceable compo-
nent. Consult your MoparŸ parts catalog for a spe-
cific part number.
OPERATION
When the exterior handle switch is depressed, with
the liftgate in the closed position. A message is sent
to the Body Control Module (BCM). The Body Con-
trol Module then sends a signal to the power liftgate
control module via the J1850 PCI data bus circuit.
The power liftgate control module then sends a sig-
nal to the power latch mounted actuator, which
moves the liftgate from the primary closed and
latched position to the open and movable position. If
the liftgate is not pulled open once the latch releases
within a few seconds, the latch will cinch closed
again.
REMOVAL
(1) Disconnect and isolate the negative battery
cable.
(2) Open the liftgate and remove the liftgate trim
panel. Refer to the Body section of the service man-
ual for the procedure.
(3) Remove the rear lamp bar assembly from the
vehicle. Refer to the Body section of the service man-
ual for the procedure.
(4) Locate the two wires going to the exterior han-
dle switch. Cut the tie strap and trace the wires to
the large electrical connector and back the wires out
of the large connector and through the grommet.
Refer to the Wiring section of the service manual for
detailed instructions.
(5) Depress the two exterior handle switch retain-
ing tabs and roll the switch out of the light bar
assembly (Fig. 14).
INSTALLATION
(1) Install the handle switch in the light bar
assembly.(2) Locate the two wires going to the exterior han-
dle switch. Install the wires through the grommet
and in the large connector. Secure with a tie strap.
Refer to the Wiring section of the service manual for
detailed instructions.
NOTE: Be certain wires are reinstalled in the correct
wire cavities. Failure to do so could result in dam-
age to the handle switch. Refer to Wiring Diagrams
if previous notes were not made.
(3) Install the rear light bar. Refer to the Body sec-
tion of the service manual for the procedure.
(4) Install the liftgate trim panel. Refer to the
Body section of the service manual for the procedure.
(5) Connect the negative battery cable.
(6) Using an appropriate scan tool, check any
erase any power liftgate control module diagnostic
trouble codes.
(7) Verify power liftgate system and handle switch
operation. Cycle the power liftgate through one com-
plete open and close cycle, this will allow the power
liftgate control module to relearn its cycle with the
new components.

Safety is of the utmost concern with the power
sliding door system. Software technology has enabled
the power sliding door control module to detect resis-
tance to door travel. This allows the power sliding
door to stop and reverse direction any time an
obstruction is felt or any of the command switches
are operated (while closing only). Battery voltage is
supplied to the power sliding door system through a
40 amp fuse, located in the Intelligent Power Module
(IPM) assembly (Fig. 3). The child lockout switch pre-
vents children from opening or actuating the power
sliding door system when desired. In the unlikely
event that the power sliding door system develops a
fault, the power sliding door can still be operated
manually from the interior or exterior door handle,
just like a standard manual sliding door.
The power sliding door control module communi-
cates on the J1850 PCI Data Bus Circuit. Therefore,
the power sliding door control module can generate
and store its own diagnostic trouble codes (DTC). A
diagnostic scan tool, such as the DRB IIItis used to
read and diagnose these trouble codes. Refer to the
Body Diagnostic Manual for a complete list of diag-
nostic routines.

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 LOCKS
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.
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. If a sliding
door is open when this is done, the sliding door will
lock when it is closed.
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.
RSPOWER LOCKS8N-39

²UNLOCK: Pressing the UNLOCK button once
will unlock the driver's side doors and activate the
illuminated entry system and disarm Vehicle Theft
Security System, if equipped. Pressing the UNLOCK
button twice within five seconds will unlock all doors
and activate the illuminated entry system.
²LEFT SLIDING DOOR: Pressing the LEFT
SLIDING DOOR BUTTON opens/closes the left
power sliding door remotely.
²RIGHT SLIDING DOOR: Pressing the RIGHT
SLIDING DOOR BUTTON opens/closes the right
power sliding door remotely.
²LIFTGATE: Pressing the LIFTGATE BUTTON

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 and mirror system, if equipped. Two primary
key fob transmitters can be programmed to actuate
memory seat and mirror setting 1 or 2. Two addi-
tional key fob transmitters can be added, but they
will not be able to operate the memory seat and mir-
ror system (Refer to 8 - ELECTRICAL/POWER
SEATS - OPERATION) and (Refer to 8 - ELECTRI-
CAL/POWER MIRRORS - OPERATION).
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 positivepin 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.
