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
IMMOBILIZER DIAGNOSIS
Refer to the 1998 PL Powertrain Diagnostic Man-
ual for complete diagnostic procedures of the immo-
bilizer system.

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,
refer to the Vehicle Theft Security System menu itemon the DRB scan tool for further diagnosis. If not
OK, repair the open circuit to the PDC fuse as
required.REMOVAL AND INSTALLATION

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.

(7) It is necessary that the window be free to slide
up and down in the glass channels. If the window is
not free to move up and down, the window lift motor
will not be able to move the glass.
(8) To determine if the glass is free, disconnect the
regulator from the glass lift plate. Remove the two
attaching nuts, and slide the window up and down by
hand. This check can not be made on a four door
vehicle.

GENERAL INFORMATION
INTRODUCTION
Electrically operated power mirrors are available
on all car lines. The mirrors are controlled by a sin-
gle switch assembly located on the driver's door trim
panel. The push button rocker switch uses L (left)
and R (right) for mirror selection and a button to
push for the desired direction of mirror movement
(Fig. 1).
The motors which operate the mirrors are part of
the mirror assembly and cannot be replaced sepa-
rately.
All vehicles are equipped with a Ignition-Off Draw
Fuse, and they are disconnected when the vehicles
are originally shipped from the factory. Disconnecting
this fuse will help prevent the battery from discharge
during storage. The fuse is located in Power Distri-
bution Center (PDC) refer to the cover for proper
location.
This fuse is included in the power mirror circuity
and should be checked if the mirrors are inoperative.
DIAGNOSIS AND TESTING
MIRROR SWITCH TEST
(1) Remove power mirror switch from mounting
position.
(2) Disconnect wiring harness at switch connector.
(3) Using an ohmmeter, test for continuity between
the terminals of the switch as shown in the Mirror
Switch Test (Fig. 2).
(4) If test results are not obtained as shown in the
Mirror Switch Test (Fig. 2), replace the switch.
