PASSENGER AIRBAG ON/OFF
SWITCH
DESCRIPTION
The passenger airbag on-off switch is standard
equipment on this model when it is not equipped
with a full size rear seat. This switch is a single pole,
single throw switch with a single integral red Light-
Emitting Diode (LED), and a non-coded key cylinder-
type actuator. The switch is located in the upper
right corner of instrument panel cluster bezel, near
the center of instrument panel to make the Off indi-
cator visible to all front seat occupants. When the
BR/BERESTRAINTS 8O - 23
PASSENGER AIRBAG (Continued)

switch is in its installed position, the only compo-
nents visible through the dedicated opening of the
cluster bezel are the switch face plate and nomencla-
ture, the key cylinder actuator, and a small round
lens with the text9Off9imprinted on it. The ªOnº
position of the switch is designated by text imprinted
upon the face plate of the switch, but is not illumi-
nated. The remainder of the switch is concealed
behind the switch face plate and the instrument
panel cluster bezel.
The passenger airbag on-off switch housing is con-
structed of molded plastic and has three integral
mounting tabs. These mounting tabs are used to
secure the switch to the back of the molded plastic
switch face plate with three small screws. The
molded plastic face plate also has three integral
mounting tabs that are used to secure the switch and
face plate unit to the instrument panel carrier with
three additional screws. Two short pigtail wires with
molded plastic connector insulators exit the back of
the switch housing and connect the switch to the
vehicle electrical system through two dedicated take
outs of the instrument panel wire harness. The har-
ness take outs are equipped with molded plastic con-
nector insulators that are keyed and latched to
ensure proper and secure switch electrical connec-
tions. The passenger airbag on/off switch cannot be
adjusted or repaired and, if faulty or damaged, the
switch must be replaced.
OPERATION
The passenger airbag on/off switch allows the cus-
tomer to turn the passenger airbag function On or
Off to accommodate certain uses of the right front
seating position where airbag protection may not be
desired. See the owner's manual in the vehicle glove
box for specific recommendations on when to enable
or disable the passenger airbag. The Off indicator of
the switch will be illuminated whenever the switch is
turned to the Off position. The ignition key is the
only key or object that should ever be inserted into
the switch. The on/off switch requires only a partial
key insertion to fully depress a spring-loaded locking
plunger. The spring-loaded locking plunger prevents
the user from leaving the key in the switch. The key
will be automatically ejected when force is not
applied. To actuate the passenger side airbag on/off
switch, insert the ignition key into the switch key
actuator far enough to fully depress the plunger and
rotate to the desired switch position. When the
switch key actuator is rotated to its clockwise stop
(the key actuator slot will be aligned with the Off
indicator lamp), the Off indicator is illuminated and
the passenger airbag is disabled. When the switch is
rotated to its counterclockwise stop (the key actuator
slot will be in a vertical position), the Off indicatorwill be extinguished and the passenger airbag is
enabled.
The passenger airbag on/off switch is connected in
series between the Airbag Control Module (ACM) and
the passenger airbag inflator unit. When the switch
is in the On position, the switch connects the ACM
directly to the passenger airbag inflator. When the
switch is in the Off position it interrupts the inflator
circuits, but replaces the normal resistance in these
circuits with an internal resistor. Thus, the ACM is
unable to distinguish the mode of the switch and still
sends an electrical signal as though it were deploying
the passenger airbag when it detects a sufficient
impact. However, the switch position should not be
changed while the ignition switch is in the On posi-
tion, as the ACM may detect a fault, record a Diag-
nostic Trouble Code (DTC), and illuminate the Airbag
indicator in response to a momentary open it senses
in the passenger airbag inflator circuits as the on/off
switch changes states.

Hard wired circuitry connects many of the VTSS
components to each other through the electrical sys-
tem of the vehicle. These hard wired circuits are
integral to several wire harnesses, which are routed
throughout the vehicle and retained by many differ-
ent methods. These circuits may be connected to each
other, to the vehicle electrical system and to the
VTSS components through the use of a combination
of soldered splices, splice block connectors, and many
different types of wire harness terminal connectors
and insulators. Refer to the appropriate wiring infor-
mation. The wiring information includes wiring dia-
grams, proper wire and connector repair procedures,
further details on wire harness routing and reten-
tion, as well as pin-out and location views for the
various wire harness connectors, splices and grounds.
OPERATION
A Central Timer Module (CTM) is used on this
model to control and integrate many of the electronic
functions and features included in the Vehicle Theft
Security System (VTSS). In the VTSS, the CTM
receives inputs indicating the status of the door ajar
switches, the door cylinder lock switch, and the igni-
tion switch. The programming in the CTM allows it
to process the information from all of these inputs
and send control outputs to energize or de-energize
the horn relay, the headlamp relay, and the VTSS
indicator. The control of these inputs and outputs are
what constitute all of the features of the VTSS. Fol-
lowing is information on the operation of each of the
VTSS features. Refer to the owner's manual in the
vehicle glove box for more information on the fea-
tures, use and operation of the VTSS.
ENABLING
The high-line or premium version of the CTM must
have the VTSS function electronically enabled in
order for the VTSS to perform as designed. The logic
in the CTM keeps its VTSS function dormant until it
is enabled using a DRBIIItscan tool. The VTSS
function of the high-line or premium CTM is enabled
on vehicles equipped with the VTSS option at the
factory, but a service replacement CTM must be
VTSS-enabled by the dealer using a DRBIIItscan
tool. Refer to the appropriate diagnostic information.
The VTSS engine no-run feature is disabled when
it is shipped from the factory. This is done by pro-
gramming within the Powertrain Control Module
(PCM). The logic in the PCM prevents the VTSS
engine no-run feature from arming until the engine
start counter within the PCM sees twenty enginestarts. The VTSS no-run feature must be enabled by
the dealer when the vehicle is received from the
assembly plant. Once the VTSS engine no-run fea-
ture has been enabled, it cannot be disabled unless
the PCM is replaced with a new unit. The same
VTSS engine no-run feature enable logic will apply
anytime the PCM is replaced with a new unit.
ARMING
Passive arming of the VTSS occurs when the vehi-
cle is exited with the key removed from the ignition
switch, the headlamps are turned off, and the doors
are locked while they are open using the power lock
switch, or locked after they are closed by turning
either front door lock cylinder to the lock position
using the key. The power lock switch will not func-
tion if the key is in the ignition switch or the head-
lamps are turned on with the driver side front door
open. The VTSS will not arm if the doors are locked
using the mechanical lock button. Active arming of
the VTSS occurs when the ªLockº button on the
Remote Keyless Entry (RKE) transmitter is
depressed to lock the vehicle. For active arming to
occur, the doors must be closed and the ignition
switch must be in the Off position when the RKE
transmitter ªLockº button is depressed. However,
once the VTSS arming process has been completed,
the ignition switch can be turned to the Accessory
position without triggering the alarm.
Once the VTSS begins passive or active arming,
the security indicator lamp in the overhead console
will flash rapidly for about fifteen seconds. This indi-
cates that the VTSS arming is in progress. Turning a
key in the ignition switch, opening a door, or unlock-
ing a door by any means during the fifteen second
arming process will cause the VTSS indicator to stop
flashing and the arming process to abort. Once the
fifteen second arming function is successfully com-
pleted, the indicator will flash at a slower rate, indi-
cating that the VTSS is armed.
DISARMING
Passive disarming of the VTSS occurs when the
vehicle is unlocked using the key to unlock either
front door. Active disarming of the VTSS occurs when
the vehicle is unlocked by depressing the ªUnlockº
button of the RKE transmitter. Once the alarm has
been activated (horn pulsing, headlamps flashing,
and the engine no-run feature), either disarming
method will also deactivate the alarm. Depressing
the ªPanicº button on the RKE transmitter willnot
disarm the VTSS.

VEHICLE THEFT SECURITY (Continued)

activates the washer pump/motor, which dispenses
washer fluid onto the windshield glass through the
washer nozzles.
When the ignition switch is in the Accessory or On
positions, battery current from a fuse in the Junction
Block (JB) is provided through a fused ignition
switch output (run-acc) circuit to the wiper motor
park switch, the wiper relay, and the multi-function
switch. The internal circuitry of the multi-function
switch provides a direct hard wired battery current
output to the low speed or high speed brushes of the
wiper motor when the Lo or Hi switch setting is
selected, which causes the wipers to cycle at the
selected speed. The intermittent wipe, and wipe-af-
ter-wash features of the wiper and washer system
are provided by the electronic intermittent wipe logic
circuit within the Central Timer Module (CTM). In
order to provide the intermittent wipe feature, the
CTM monitors the wiper switch state and the wiper
motor park switch state. In order to provide the
wipe-after-wash feature, the CTM monitors both the
washer switch state and the wiper motor park switch
state. When a Delay position is selected with the
multi-function switch control knob, the CTM logic cir-
cuit responds by calculating the correct delay inter-
val. The CTM then energizes the wiper relay by
pulling the relay control coil to ground. The ener-
gized wiper relay directs battery current through the
normally open contact of the relay back through the
internal circuitry of the multi-function switch to the
low speed brush of the wiper motor. The CTM moni-
tors the wiper motor operation through the wiper
park switch sense circuit, which allows the CTM to
determine the proper timing to begin the next wiper
blade sweep. The normal delay intervals are driver
adjustable from about one-half second to about eigh-
teen seconds.
The high-line and premium CTM also provides a
speed sensitive intermittent wipe feature. By moni-
toring vehicle speed messages received from the Pow-
ertrain Control Module (PCM) over the Chrysler
Collision Detection (CCD) data bus network, the
high-line or premium CTM is able to adjust the delay
intervals to compensate for vehicle speed. Above
about sixteen kilometers-per-hour (ten miles-per-
hour) the delay is driver adjustable from about one-
half second to about eighteen seconds. Below about
sixteen kilometers-per-hour (ten miles-per-hour) the
delay times are doubled by the CTM, from about one
second to about thirty-six seconds.
When the Off position of the multi-function switch
wiper control knob is selected, one of two events is
possible. The event that will occur depends upon the
position of the wiper blades on the windshield at the
moment that the Off position is selected. If the wiper
blades are in the down position on the windshieldwhen the Off position is selected, the park switch
that is integral to the wiper motor is closed to ground
and the wiper motor ceases to operate. If the wiper
blades are not in the down position on the windshield
at the moment the Off position is selected, the park
switch is closed to battery current through a fused
ignition switch output (run-acc) circuit. The park
switch sense circuit directs this battery current to
the low speed brush of the wiper motor through the
normally closed contact of the wiper relay and the
internal Off position circuitry of the multi-function
switch. This causes the wiper motor to continue run-
ning until the wiper blades are in the down position
on the windshield and the park switch is again
closed to ground.
When the Wash position of the multi-function
switch is selected, the Wash position circuitry within
the switch directs battery current to the washer
pump/motor. The CTM monitors the washer switch
state through a washer switch sense input. When the
washer switch is closed with the wiper system turned
Off, the CTM operates the wiper motor through the
wiper relay in the same manner as it does to provide
the Delay mode operation. After the state of the
washer switch changes to open, the CTM monitors
the wiper motor through the wiper park switch sense
circuit, which allows the CTM to monitor the number
of wiper blade sweeps.
Proper testing of the CTM, the PCM, or the CCD
data bus vehicle speed messages requires a DRBIIIt
scan tool. Refer to the appropriate diagnostic infor-
mation. Refer to the owner's manual in the vehicle
glove box for more information on the features and
operation of the wiper and washer system.
DIAGNOSIS AND TESTING - WIPER &
WASHER SYSTEM
WIPER SYSTEM
The diagnosis found here addresses an electrically
inoperative wiper system. If the wiper motor oper-
ates, but the wipers do not move on the windshield,
replace the faulty wiper module. If the wipers oper-
ate, but chatter, lift, or do not clear the glass, clean
and inspect the wiper system components as
required. (Refer to 8 - ELECTRICAL/WIPERS/
WASHERS - INSPECTION) and (Refer to 8 - ELEC-
TRICAL/WIPERS/WASHERS - CLEANING). Refer to
the appropriate wiring information. The wiring infor-
mation includes wiring diagrams, proper wire and
connector repair procedures, details of wire harness
routing and retention, connector pin-out information
and location views for the various wire harness con-
nectors, splices and grounds.
The following tests will help to diagnose the hard
wired components and circuits of the wiper system.
