DESCRIPTION AND OPERATION
INTRODUCTION
All doors can be locked or unlocked electrically by
operating the switch on either front door panels.
The rear doors can be locked or unlocked by actu-
ation of the front door switch, or can be locked or
unlocked mechanically and independently with their
respective locking knobs.
The front doors can be locked or unlocked mechan-
ically with the locking knob regardless of electrical
locking and unlocking actuation with the front door
knobs.
The right and left front door can be locked or
unlocked mechanically from the outside with the key
or electrically as described above.
CHILD PROTECTION LOCK
The child protection lock is on the rear door only.
The lock will disable the inside door handle from
opening the door when engaged. The lock is part of
the latch/lock assembly. The lock is engaged by mov-
ing a lever that is located on the rearward inside
edge of the door.
DIAGNOSIS AND TESTING
DOOR LOCK MOTOR
Make certain battery is in normal condition before
circuits are tested.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 maybe 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 (Fig. 1) To unlock the door reverse the wire con-
nections at the motor pin terminals. If these results
are NOT obtained, replace the door latch assembly.
DOOR LOCK SWITCH
Remove the switch from its mounting location.
Using an ohmmeter, refer to (Fig. 2) to determine if
continuity is correct in the Lock and Unlock switch
positions. If these results are not obtained, replace
the switch.
WIRING
The following wiring test sequence determines
whether or not voltage is continuous through the
body harness to switch.
(1) Remove left side switch from door trim panel.
(2) Carefully separate multiple terminal block on
wiring harness from switch body.
PLPOWER DOOR LOCKS 8P - 1

(3) Connect one lead of test light to a ground ter-
minal. Touch other test light lead to Red Wire termi-
nal.
(a) If test light comes on, the wiring circuit
between the battery and switch is functional.
(b) If test light does not come on, check fuse 3 in
the fuse block or for a open circuit.

GENERAL INFORMATION
INTRODUCTION
The key fob transmitter has three buttons to actu-
ate and program the Remote Keyless Entry (RKE)
system (Fig. 1).
²UNLOCK: Actuating the UNLOCK button once
will unlock the driver door and activate the illumi-
nated entry system. Actuating the UNLOCK button
twice within five seconds will unlock all doors.
²LOCK: Actuating the LOCK button locks all
doors and sounds horn (chirp). The chirp verifies the
door lock operation.
²PANIC: Actuating the PANIC button sounds the
horns and alternately flashes the headlamps and
parking lamps. The panic alarm will remain on for
one minute, until the PANIC button is actuated
again or the ignition is switched to the RUN position.
²The Remote Keyless Entry Module is capable of
retaining the transmitter Vehicle Access Code (VAC)
in memory even after vehicle power has been inter-
rupted.
DESCRIPTION AND OPERATION
VEHICLE ACCESS CODE (VAC) PROGRAMMING
The system allows locking and unlocking of vehicle
door(s) by remote control using a hand held radio fre-
quency transmitter. The ignition switch must be OFF
before the panic function can be activated with the
transmitter.
The receiver may receive VAC signals from two
transmitters. Each transmitter has its own VehicleAccess Code and the code is programmed and stored
into receiver memory. If the transmitter is replaced
or a second transmitter is added, the codes of both
units have to be reprogrammed into the receiver
memory. If a receiver module is replaced, both the
transmitter codes must be stored in the new receiver
memory.
OPERATION
The transmitter has three buttons for operation
(Fig. 1). They are LOCK, UNLOCK and PANIC.
The receiver is capable of retaining all Vehicle
Access Codes (VAC) even when power is removed.
Each remote keyless entry module (RKE) must
have at least one and no more than two transmitters.

REMOTE KEYLESS ENTRY SYSTEM
When trouble shooting problems with the Remote
Keyless Entry System, always verify that the power
door lock/unlock switches are functional. If the doors
do not lock/unlock refer to Group 8W, Wiring Dia-
gram for Pin and wiring locations.
If the following items do not work:
²Remote keyless entry system
²Radio/clock
²Door lock switches
A blown fuse is the probable cause. Check fuses 2,
3 and 11 in the fuse block. To check for a blown fuse,
pull the fuse out slightly, but maintain contact
between the fuse terminals and the terminals in fuse
block. Using the voltmeter probe, check both termi-
nals for 12 volts. If only one terminal measures bat-
tery voltage, the circuit breaker is defective and must
be replaced. If neither terminal measures battery
voltage, check the high current fuses 3 and 11 in the
Power Distribution Center (PDC). The PDC is located
in the engine compartment. If fuse(s) are NOT OK,
replace fuse(s) or repair as necessary. If fuses are
OK, check for an open or shorted circuit to the Power
Distribution Center, repair as needed.

lent. Battery life is about one to two years.
CAUTION: Do not touch the battery terminals or
handle the batteries any more than necessary.
Hands must be clean and dry.
RKE TRANSMITTER RANGE
Normal operation range is up to about a distance
of 7 meters (23 ft.) of the vehicle. Range may be bet-
ter or worse depending on the environment aroundthe vehicle. Closeness to a radio frequency transmit-
ter such as a radio station tower may degrade oper-
ational range, while range in an open field will be
enhanced.

transmitter vehicle access codes into the memory of
the immobilizer receiver. Refer to the Vehicle Theft
Security System menu item on the DRB scan tool for
the procedures.
The immobilizer receiver recognizes the Lock and
Unlock signals received from the programmed immo-
bilizer transmitters. If the code sent by the key fob
transmitter is recognized as valid by the Immobilizer
module, it will decode the Crankshaft Position Sensor
signal, enable the starter circuit, and allow the
engine to run.
The immobilizer receiver is mounted to the dash
panel with a hook and loop fastener patch. It is
located behind the instrument cluster and above the
heater-A/C housing. The receiver is connected to the
dash panel cross-body wiring harness. (Fig. 1)
For diagnosis of the vehicle immobilizer receiver or
the CCD data bus, a DRB scan tool is required. Refer
to the Vehicle Theft Security System menu item of
the DRB scan tool for the procedures. The immobi-
lizer receiver contains no servicable parts. If faulty,
the unit must be replaced.
IMMOBILIZER TRANSMITTER
The vehicle immobilizer system includes two trans-
mitters that are supplied with the vehicle when it isshipped from the factory. Each of the two transmit-
ters is equipped with two buttons labeled with Inter-
national Standards Organization (ISO) symbols for
Lock, and Unlock. Two spare batteries (enough for
one transmitter) are also shipped with the transmit-
ters. The transmitters are equipped with a key ring
and are designed to serve as a key fob. The operating
range of the radio frequency transmitter signal is up
to 7 meters (23 feet) from the immobilizer receiver.
Each transmitter has a different vehicle access
code, which must be programmed into the memory of
the immobilizer receiver in the vehicle in order to
operate the immobilizer system. The two transmit-
ters shipped with the vehicle have their vehicle
access codes programmed into the receiver at the fac-
tory. A DRB scan tool must be used to program new
or additional transmitter vehicle access codes into
the memory of the immobilizer receiver. Refer to the
Vehicle Theft Security System menu item on the
DRB scan tool for the procedures.
Each transmitter operates on two Duracell DL2016
(or equivalent) batteries. Typical battery life is from
one to two years.
POWER-UP MODE
When the vehicle immobilizer system senses that
the vehicle battery has been disconnected and recon-
nected, it enters its power-up mode. If the immobi-
lizer system was armed prior to the battery
disconnect, the system remains armed when the bat-
tery is reconnected.
If the immobilizer system was disarmed prior to
the battery disconnect, the system will remain dis-
armed if the battery is reconnected within five min-
utes. The system will passively arm itself when the
battery is reconnected more than five minutes after a
battery disconnect or failure. After any passive arm-
ing, the system will have to be actively disarmed
using one of the transmitters.
The power-up mode logic also applies if the battery
goes dead, and battery jump-starting is attempted.
The engine no-run feature will prevent the engine
from operating until the vehicle immobilizer system
has been actively disarmed.
DIAGNOSIS AND TESTING

NOTE: The following tests may not prove conclu-
sive in the diagnosis of this system. The most reli-
able, efficient, and accurate means to diagnose the
Vehicle Immobilizer System involves the use of a
DRB scan tool. Refer to the Vehicle Theft Security
System menu item on the DRB scan tool for the
procedures.
The vehicle immobilizer system and the Chrysler
Collision Detection (CCD) data bus network should
be diagnosed using the DRB scan tool. The DRB will
allow confirmation that the CCD data bus is func-
tional, that the immobilizer receiver is placing the
proper messages on the CCD data bus, and that the
Powertrain Control Module (PCM) is receiving the
CCD data bus messages. Refer to the Vehicle Theft
Security System menu item on the DRB scan tool for
the procedures. Refer to 8W-39 - Vehicle Theft Secu-
rity System in Group 8W - Wiring Diagrams for com-
plete circuit descriptions and diagrams.
(1) With the ignition switch in the Off position,
depress the Lock or Unlock button of the immobilizer
transmitter. Listen for the immobilizer receiver to
issue an audible chirp (Unlock) or chirps (Lock). If
OK, go to Step 2. If not OK, replace the transmitter
batteries with known good units and repeat Step 1. If
still not OK, go to Step 2.
(2) Check the fuse in the Power Distribution Cen-
ter (PDC). If OK, go to Step 3. If not OK, repair the
shorted circuit or component as required and replace
the faulty fuse.
(3) Disconnect and isolate the battery negative
cable. Unplug the wire harness connector at the
immobilizer receiver. Check for continuity between
the ground circuit cavity of the immobilizer receiver
wire harness connector and a good ground. There
should be continuity. If OK, go to Step 4. If not OK,
repair the open circuit to ground as required.
(4) Connect the battery negative cable. Check for
battery voltage at the fused B(+) circuit cavity of the
immobilizer receiver wire harness connector. If OK,

GENERAL INFORMATION
INTRODUCTION
The window lift motors are of the permanent mag-
net type. A battery positive and negative connection
to either of the two motor terminals will cause the
motor to rotate in one direction. Reversing current
through these same two connections will cause the
motor to rotate in the opposite direction.
Each individual motor is grounded through the
master switch.
DIAGNOSIS AND TESTING
WIRING TEST
The following wiring test determines whether or
not voltage is continuous through the body harness
to switch.
Remove switch for testing. Connect a voltmeter
positive lead to Pin 4 and negative lead to Pin 3 of
the switch connector (Fig. 1). Turn ignition switch to
the ON position. Voltmeter should read battery volt-
age. If OK, go to Window Switch Test. If not OK,
check the 30 amp circuit breaker behind the fuse
block or for a broken wire. For wiring, specific con-
nector type and location, refer to Group 8W, Wiring
Diagrams.
WINDOW SWITCH TEST
Remove the switch from its mounting, refer to the
Window Switch Removal and Installation proce-
dures.. Using an ohmmeter, refer to the test proce-
dures below, Driver Side or Passenger Side Window
Switch Continuity Test to determine if continuity is
correct (Fig. 2) and (Fig. 3). If the results are not
obtained, replace the switch.
WINDOW MOTOR TEST
(1) Remove door trim panel, refer to Group 23
Body for removal procedures.(2) Connect positive (+) lead from a test battery to
either of the two motor terminals.
(3) Connect negative (-) lead from test battery to
remaining motor terminal.
(4) The motor should now rotate in one direction to
either move window up or down.
(a) If window happens to already be in full UP
position and motor is connected so as to move it in
UP direction no movement will be observed.
(b) Likewise, motor connected to move window
in DOWN direction no movement will be observed
if window is already in full DOWN position.
(c) Reverse battery leads in Step 2 and Step 3
and window should now move. If window does not
move, remove motor. See below for motor removal
from vehicle.
(5) If window moved completely up or down, the
test leads should be reversed one more time to com-
plete a full window travel inspection.
(6) If window does not move, check to make sure
that it is free.
