(5) Refer to the appropriate wiring information.
The wiring information 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 connectors, splices and grounds. Check
the continuity in each circuit between the inoperative
power window and lock switch and bezel unit wire
harness connector cavities and the corresponding
power window motor wire harness connector cavities.
If OK, (Refer to 8 - ELECTRICAL/POWER WIN-
DOWS/WINDOW MOTOR - DIAGNOSIS AND TEST-
ING). If not OK, repair the open circuit(s) as
required.
NOTE: The passenger side power window switch
receives the ground feed for operating the passen-
ger side power window motor through the driver
side power window switch and wire harness con-
nector.
POWER WINDOW SWITCH
DESCRIPTION
The power windows are controlled by two-way
switches integral to the power window and lock
switch and bezel unit on the trim panel of each front
door. A second power window switch in the driver
side switch and bezel unit allows the driver to control
the passenger side window. A Light-Emitting Diode(LED) in the paddle of each switch is illuminated
whenever the ignition switch is in the On position.
OPERATION
The power window switch for the driver side front
door has an Auto label on it. This switch has a sec-
ond detent position beyond the normal Down position
that provides an automatic one-touch window down
feature. This feature is controlled by an electronic
circuit and a relay that are integral to the driver side
front door power window and lock switch unit.
The power window switches control the battery
and ground feeds to the power window motors. The
passenger side power window switch receives a
ground feed through the driver side power window
switch for operating the passenger side power win-
dow motor.
The power window and lock switch and bezel unit
cannot be repaired and, if faulty or damaged, the
entire switch and bezel unit must be replaced.
DIAGNOSIS AND TESTING - POWER WINDOW
SWITCH
The auto down feature of the driver side power
window switch is controlled by an electronic circuit
within the switch unit. The auto down circuitry is
activated when the driver side power window switch
is moved to the second detent in the Down direction.
The outputs from the auto down circuitry are carried
through the same switch pins that provide the nor-
mal down function. The auto down circuit cannot be
tested. If the driver side power window switch conti-
nuity tests are passed, but the auto down feature is
inoperative, replace the faulty driver side power win-
dow switch unit.
The Light-Emitting Diode (LED) illumination
lamps for all of the power window and lock switch
and bezel unit switch paddles receive battery current
through the power window circuit breaker in the
junction block. If all of the LEDs are inoperative in
either or both power window and lock switch and
bezel units and the power windows are inoperative,
perform the diagnosis for Power Window System in
this group. If the power windows operate, but any or
all of the LEDs are inoperative, the power window
and lock switch and bezel unit with the inoperative
LED(s) is faulty and must be replaced. For circuit
descriptions and diagrams, refer to the appropriate
wiring information. The wiring information 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 connectors, splices
and grounds.

WINDOW MOTOR
DESCRIPTION
A permanent magnet reversible motor moves the
window regulator through an integral gearbox mech-
anism. A positive and negative battery connection to
the two motor terminals will cause the motor to
rotate in one direction. Reversing the current
through these same two connections will cause the
motor to rotate in the opposite direction.
In addition, each power window motor is equipped
with an integral self-resetting circuit breaker to pro-
tect the motor from overloads. The power window
motor and gearbox assembly cannot be repaired and,
if faulty or damaged, the entire power window regu-
lator assembly must be replaced.
DIAGNOSIS AND TESTING - WINDOW MOTOR
For circuit descriptions and diagrams, refer to the
appropriate wiring information. The wiring informa-
tion includes wiring diagrams, proper wire and con-
nector 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. Before you proceed withthis diagnosis, confirm proper switch operation.
(Refer to 8 - ELECTRICAL/POWER WINDOWS/
POWER WINDOW SWITCH - DIAGNOSIS AND
TESTING).
(1) Disconnect and isolate the battery negative
cable. Remove the trim panel from the door with the
inoperative power window.
(2) Unplug the power window motor wire harness
connector. Apply 12 volts across the motor terminals
to check its operation in one direction. Reverse the
connections across the motor terminals to check the
operation in the other direction. Remember, if the
window is in the full up or full down position, the
motor will not operate in that direction by design. If
OK, repair the circuits from the power window motor
to the power window switch as required. If not OK,
replace the faulty motor.
(3) If the motor operates in both directions, check
the operation of the window glass and lift mechanism
through its complete up and down travel. There
should be no binding or sticking of the window glass
or lift mechanism through the entire travel range. If
not OK, (Refer to 23 - BODY/DOOR - FRONT/WIN-
DOW REGULATOR - REMOVAL).
REMOVAL
The power window motor and mechanism is inte-
gral to the power window regulator unit. If the power
window motor or mechanism is faulty or damaged,
the entire power window regulator unit must be
replaced. (Refer to 23 - BODY/DOOR - FRONT/WIN-
DOW REGULATOR - REMOVAL) for the window

SEAT BELT SWITCH
DESCRIPTION
The seat belt switch is a small, normally closed,
single pole, single throw, leaf contact, momentary
switch. Only one seat belt switch is installed in the
vehicle, and it is integral to the buckle of the driver
seat belt buckle-half, located near the inboard side of
the driver side front seating position. The seat belt
switch is connected to the vehicle electrical system
through a two-wire pigtail wire and connector on the
seat belt buckle-half, which is connected to a wire
harness connector and take out of the body wire har-
ness.
The seat belt switch cannot be adjusted or repaired
and, if faulty or damaged, the entire driver seat belt
buckle-half unit must be replaced.
OPERATION
The seat belt switch is designed to control a path
to ground for the seat belt switch sense input of the
Electro-Mechanical Instrument Cluster (EMIC).
When the driver side seat belt tip-half is inserted in
the seat belt buckle, the switch opens the path to
ground; and, when the driver side seat belt tip-half is
removed from the seat belt buckle, the switch closes
the ground path. The switch is actuated by the latch
mechanism within the seat belt buckle. The EMIC
monitors the driver seat belt switch status, then con-
trols the seatbelt indicator and sends hard wired
chime requests to the Central Timer Module (CTM)
based upon that input.The seat belt switch receives ground through its
pigtail wire connection to the body wire harness from
another take out of the body wire harness. An eyelet
terminal connector on that ground take out is
secured under a nut to a ground stud on the left
lower B-pillar (standard cab models) or the left lower
cowl side inner panel (club cab and quad cab models).
The seat belt switch is connected in series between
ground and the seat belt switch sense input of the
EMIC.

to enter the servo and pull open the throttle plate
using the cable. When the PCM breaks the ground,
the solenoid closes and no more vacuum is allowed to
enter the servo. The PCM also operates the vent sole-
noid via ground. The vent solenoid opens and closes a
passage to bleed or hold vacuum in the servo as
required.
The PCM duty cycles the vacuum and vent sole-
noids to maintain the set speed, or to accelerate and
decelerate the vehicle. To increase throttle opening,
the PCM grounds the vacuum and vent solenoids. To
decrease throttle opening, the PCM removes the
grounds from the vacuum and vent solenoids. When
the brake is released, if vehicle speed exceeds 30
mph to resume, 35 mph to set, and the RES/ACCEL
switch has been depressed, ground for the vent and
vacuum circuits is restored.

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 DRBIIIž scan 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 DRBIIIž scan
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 engine
starts. 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 sameVTSS 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.
POWER-UP MODE
When the armed VTSS senses that the battery has
been disconnected and reconnected, it enters its pow-
er-up mode. In the power-up mode the alarm system
remains armed following a battery failure or discon-
nect. If the VTSS was armed prior to a battery dis-
connect or failure, the technician or vehicle operator
will have to actively or passively disarm the alarm
system after the battery is reconnected. The pow-
8Q - 2 VEHICLE THEFT SECURITYBR/BE
VEHICLE THEFT SECURITY (Continued)

er-up mode will also apply if the battery goes dead
while the system is armed, and battery jump-starting
is attempted. The engine no-run feature will prevent
the engine from starting until the alarm system has
been actively or passively disarmed. The VTSS will
be armed until the technician or vehicle operator has
actively or passively disarmed the alarm system. If
the VTSS is in the disarmed mode prior to a battery
disconnect or failure, it will remain disarmed after
the battery is reconnected or replaced, or if jump-
starting is attempted.
TAMPER ALERT
The VTSS tamper alert feature will sound the horn
three times upon disarming, if the alarm was trig-
gered and has since timed-out (about fifteen min-
utes). This feature alerts the vehicle operator that
the VTSS alarm was activated while the vehicle was
unattended.
DIAGNOSIS AND TESTING - VEHICLE THEFT
SECURITY SYSTEM
The VTSS-related hard wired inputs to and out-
puts from the high-line or premium Central Timer
Module (CTM) may be diagnosed and tested using
conventional diagnostic tools and procedures. 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 harness
connectors, splices and grounds.
However, conventional diagnostic methods may not
prove conclusive in the diagnosis of the CTM, the
Powertrain Control Module (PCM), or the Chrysler
Collision Detection (CCD) data bus network. In order
to obtain conclusive testing of the VTSS, the CTM,
the PCM, and the CCD data bus network must also
be checked. The most reliable, efficient, and accurate
means to diagnose the VTSS requires the use of a
DRBIIIž scan tool. Refer to the appropriate diagnos-
tic information. The DRBIIIž scan tool can provide
confirmation that the CCD data bus network is func-
tional, that all of the electronic modules are sending
and receiving the proper messages over the CCD
data bus, and that these modules are receiving the
proper hard wired inputs and responding with the
proper hard wired outputs needed to perform their
functions. See the ªVehicle Theft Security Systemº
menu item on the DRBIIIž scan tool.

VTSS INDICATOR
DESCRIPTION
The Vehicle Theft Security System (VTSS) indica-
tor consists of a red Light-Emitting Diode (LED)
located on the electronic circuit board of the Compass
Mini-Trip Computer (CMTC) within the overhead
console. The LED extends through a hole in the
CMTC lens located near the forward end of the over-
head console housing near the windshield.
The VTSS indicator cannot be adjusted or repaired
and, if faulty or damaged, the entire CMTC unit
must be replaced. (Refer to 8 - ELECTRICAL/OVER-
HEAD CONSOLE/COMPASS/MINI-TRIP COM-
PUTER - DESCRIPTION).
OPERATION
The Vehicle Theft Security System (VTSS) indica-
tor gives a visible indication of the VTSS arming sta-
tus. One side of Light-Emitting Diode (LED) in the
VTSS indicator is connected to battery current
through a fused B(+) circuit and a fuse in the Junc-
tion Block (JB), so the indicator remains functional
regardless of the ignition switch position. The other
side of the LED is hard wired to the Central Timer
Module (CTM), which controls the operation of the
VTSS indicator by pulling this side of the LED cir-
cuit to ground. When the VTSS arming is in
progress, the CTM will flash the LED rapidly on and
off for about fifteen seconds. When the VTSS has
been successfully armed, the CTM will flash the LED
on and off continually at a much slower rate until
the VTSS has been disarmed. The VTSS indicator
can be diagnosed using conventional diagnostic tools
and methods.
DIAGNOSIS AND TESTING - VTSS INDICATOR
The diagnosis found here addresses an inoperative
Vehicle Theft Security System (VTSS) indicator con-
dition. If the problem being diagnosed is related to
indicator accuracy, be certain to confirm that the
problem is with the indicator and not with an inop-
