SPEED CONTROL SWITCHES
There are two separate switch pods that operate
the speed control system. The steering-wheel-
mounted switches use multiplexed circuits to provide
inputs to the PCM for ON, OFF, RESUME, ACCEL-
ERATE, SET, DECEL and CANCEL modes. Refer to
the owner's manual for more information on speed
control switch functions and setting procedures.When speed control is selected by depressing the
ON switch, the PCM allows a set speed to be stored
in RAM for speed control. To store a set speed,
depress the SET switch while the vehicle is moving
at a speed between 30 and 85 mph. In order for the
speed control to engage, the brakes cannot be
applied, nor can the gear selector be indicating the
transmission is in Park or Neutral.
The speed control can be disengaged manually by:
²Stepping on the brake pedal
²Depressing the OFF switch
²Depressing the CANCEL switch.
NOTE: Depressing the OFF switch or turning off
the ignition switch will erase the set speed stored
in the PCM.
For added safety,the speed control system is pro-
grammed to disengaged for any of the following con-
ditions:
²An indication of Park or Neutral
²An rpm increase without a VSS signal increase
(indicates that the clutch has been disengaged)
²Excessive engine rpm (indicates that the trans-
mission may be in a low gear)
²The VSS signal increases at a rate of 10 mph
per second (indicates that the co-efficient of friction
between the road surface and tires is extremely low)
²The VSS signal decreases at a rate of 10 mph
per second (indicates that the vehicle may have
decelerated at an extremely high rate)
²If the actual speed is not within 20 mph of the
set speed
The previous disengagement conditions are pro-
grammed for added safety.
Once the speed control has been disengaged,
depressing the ACCEL switch when speed is greater
than 25 mph restores the vehicle to the target speed
that was stored in the PCM.
NOTE: Depressing the OFF switch will erase the
set speed stored in the PCM's RAM.
While the speed control is engaged, the driver can
increase the vehicle speed by depressing the ACCEL
switch. The new target speed is stored in the PCM
when the ACCEL is released. The PCM also has a
9tap-up9feature in which vehicle speed increases at a
rate of approximately 2 mph for each momentary
switch activation of the ACCEL switch. The PCM
also provides a means to decelerate without disen-
gaging speed control. To decelerate from an existing
recorded target speed, depress and hold the COAST
switch until the desired speed is reached, then
release the switch.

The windshield wipers will only operate with the
ignition switch in the ACCESSORY or IGNITION
RUN position. The wiper circuit is protect against
over loads by a fuse in the fuse block and a circuit
breaker within the wiper motor. This protects the cir-
cuitry of the wiper system and the vehicle.
The wiper motor has permanent magnet fields.
The intermittent wiper system, in addition to low
and high speed, has a delay mode and a pulse wipe
mode. The delay mode has a range of 1 to 15 seconds.
Pulse wipe is accomplished by momentarily moving
the stalk lever into the WASH position while the
wiper switch is in either OFF or DELAY position.
The wiper blades then sweep once or twice and
return to the previous wiper switch mode, OFF or
DELAY.The intermittent wiper function is integral to the
wiper switch. All electronics and relay are inside the
switch assembly.
The wiper system completes the wipe cycle when
the switch is turned OFF. The blades park in the
lowest portion of the wipe pattern.
DESCRIPTION AND OPERATION
WIPER BLADES
Wiper blades, exposed to the weather for a long
period of time, tend to lose their wiping effectiveness.
Periodic cleaning of the wiper blade is suggested to
remove the accumulation of salt and road film. The
wiper blades, arms, and windshield should be
cleaned with a sponge or cloth and a mild detergent
or nonabrasive cleaner. If the blades continue to
streak or smear, they should be replaced. The right
and left wipers are different blade lengths. The
driver side length is 525 mm and the passenger side
length is 450 mm. The blades should not be inter-
changed.

SERVICE PROCEDURES
CLEANUP PROCEDURE
Roll or fold the passenger airbag towards the
instrument panel surface and close the door over the
folded bag. Then tape the door shut.
Use a vacuum cleaner to remove any residual pow-
der from the vehicle interior. Work from the outside
in to avoid kneeling or sitting in a contaminated
area. Vacuum the heater and A/C outlets as well (Fig.
4). If the heater or air conditioner was in RECIRC
mode at time of airbag deployment, operate blower
motor on low speed and vacuum powder residue
expelled from the heater and A/C outlets. Multiple
vacuum cleaning may to necessary to decontaminate
the interior of the vehicle.
NOTE: Dispose deployed airbag properly, contact
dealer or government agency for disposal recom-
mendations.
SERVICE OF DEPLOYED AIRBAG MODULE

After a Driver Airbag Module has been deployed
the following components must be replaced becausethey cannot be reused. Other driver airbag system
components are replaced if damaged.
²Driver Airbag Module
²Clockspring assembly
PASSENGER AIRBAG
After a Passenger Airbag Module has been
deployed the following components must be replaced
because they cannot be reused.
²Passenger Airbag Module
²Right trim panel
The lower instrument panel knee blocker, top
cover, and any other components should be replaced
if damaged.
HANDLING AIRBAG MODULE
DEPLOYED MODULE
The vehicle interior may contain a very small
amount of sodium hydroxide powder, a by-product of
airbag deployment. Sodium hydroxide powder can
irritate the skin, eyes, nose and throat. Wear safety
glasses, rubber gloves, and long sleeved clothing
when cleaning any of the powder residue from the
vehicle.
If you find that the cleanup is irritating your skin,
run cool water over the affected area. Also, if you
experience nasal or throat irritation, exit the vehicle
for fresh air until the irritation ceases. If irritation
continues, see a physician.
UNDEPLOYED
The airbag module(s) must be stored in its original
special container until used for service. At no time
should a source of electricity be permitted near the
inflator on the back of an airbag module. When car-
rying or handling an undeployed airbag module, the
trim side of the airbag should be pointing away from
the body to minimize possibility of injury if acciden-

DESCRIPTION AND OPERATION
INTRODUCTION
For proper operation of the Rear Window Defogger
system refer to the Owner's Manual.
The system consists of a rear glass with two verti-
cal bus bars and a series of electrically connected
grid lines fired on the inside surface. A control switch
and a timer relay combined into a single assembly is
used on all models (Fig. 1).
Circuit protection is provided by a maxi fuse,
located in the Power Distribution Center, for the
heated grid circuit and by a fuse for the relay control
circuit.
When the switch is turned to the ON position, cur-
rent is directed to the rear defogger grid lines. The
heated grid lines heat the rear glass to clear the sur-
face of fog or frost.
CAUTION: Grid lines can be damaged or scraped
off with sharp instruments, care should be taken in
cleaning glass or removing foreign materials,
decals or stickers. Normal glass cleaning solvents
or hot water used with rags or toweling is recom-
mended.
REAR WINDOW DEFOGGER SWITCH
The rear window defogger switch is a control
switch and timer relay integrated into a single panel
mounted assembly. Actuating the switch energizes
the circuit which allows current to flow through the
grid lines. Upon initial actuation for approximately
eight to ten minutes, or until either the switch or
ignition is turned off. An indicating lamp illuminates
a lens inlaid in the control switch.
DIAGNOSIS AND TESTING
DEFOGGER SYSTEM
Electrically heated rear window defogger operation
can be checked in vehicle in the following manner:
(1) Turn ignition switch to the ON position.
(2) Connect an ammeter in series with the battery.
Push the defogger control switch to the ON position.
A distinct increase in amperage draw should be
noted.
(3) The rear window defogger operation can be
checked by feeling the glass. A distinct difference in
temperature between the grid lines and adjacent
clear glass can be detected in three to four minutes
of operation.
(4) Using a DC voltmeter, connect negative lead to
Point B, and the positive lead to Point A (Fig. 2). The
voltmeter should read 10-14 volts.
(5) Step 2, Step 3 or Step 4 above will confirm
system operation. Indicator light illumination means
that there is power available at the output of the
relay only, and does not necessarily verify system
operation.

parking lamps out put. Press the panic button and
check for a voltage pulse (Fig. 2).
(2) If no voltage pulse is measured, replace the
receiver. If voltage OK, repair circuit to the parking
lamps as necessary.
(3) Connect the meter to Pin 5 of the black connec-
tor and to ground to test head lamps out put. Press
the panic button and check for a voltage pulse (Fig.
2).
(4) If no voltage pulse is measured, replace the
receiver. If voltage OK, repair circuit to the head
lamps as necessary.
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.

DESCRIPTION AND OPERATION
IMMOBILIZER SYSTEM
The Immobilizer system includes the following
unique items:
²An immobilizer module receiver that controls
system operation and also controls the RKE and Illu-
minated entry systems, if equipped.
²An encoded Crankshaft Position Sensor for the
ignition system. The Immobilizer module decodes the
signal from the crankshaft so the PCM can recognize
it as a valid Crankshaft Position Sensor signal, and
allow the engine to run.
²A wiring harness that interconnects the crank-
shaft sensor, the immobilizer receiver, and the PCM.
²Two key fob transmitters.
The Immobilizer System prevents unauthorized
operation of the vehicle by disabling the engine and
starter. The system will NOT allow the vehicle to
start unless the UNLOCK button on the RKE trans-
mitter is pressed. The system will be activated after
turning the ignition switch to the OFF position and
using one of the following methods.
(1) Press the LOCK button on the RKE transmit-
ter.
(2) LOCK the doors by pressing a power lock but-
ton switch.
(3) LOCK the driver or passenger door using the
key.
²The Security light will flash, for about 16 sec-
onds, indicating that the engine and starter will be
disabled.
²The Security light remaining on, indicates the
system is not operational.
²The Immobilizer will activate automatically
within 10 minutes of the ignition switch being in the
OFF position, whether the vehicle has been locked or
unlocked.²An attempt to start the vehicle without pressing
the UNLOCK button on the RKE transmitter will
result in a warning chime and the Security light
flashing.
NOTE: The ignition switch must be in the OFF posi-
tion in order for the system to be activated, whether
the doors are closed or not.
IMMOBILIZER RECEIVER
The immobilizer receiver is programmed to
respond to the Lock and Unlock radio signals issued
by the immobilizer transmitters. The receiver will
only respond to the radio signals of transmitters (up
to four) whose vehicle access codes have been stored
in the receiver's electronic memory. The receiver is
programmed at the assembly plant with the vehicle
access codes of the two transmitters that are shipped
with the vehicle.
The immobilizer receiver also has a central pro-
cessing unit, which contains the immobilizer system
logic. The programming in the immobilizer receiver
allows the system to learn and retain transmitter
vehicle access codes, as well as to communicate with
the Powertrain Control Module (PCM) and/or the
DRB scan tool on the Chrysler Collision Detection
(CCD) data bus network.
The CCD data bus network allows the sharing of
sensor information. This helps to reduce wiring har-
ness complexity, reduce internal controller hardware,
and reduce component sensor current loads. At the
same time, the CCD data bus network provides
increased reliability and enhanced diagnostic capabil-
ities.
Each immobilizer transmitter has a different vehi-
cle access code, which must be programmed into the
memory of the immobilizer receiver in the vehicle in
order to operate the immobilizer system. A DRB scan
tool must be used to program new or additional
PLIMMOBILIZER SYSTEM 8Q - 1

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.
