DESCRIPTION - POWER LOCK SYSTEM
Two different power lock systems are offered as
optional factory-installed equipment on this model.
Both power lock systems are offered only on models
that are also equipped with power windows. On mod-
els without the optional Remote Keyless Entry (RKE)
system, a base version of the Central Timer Module
(CTM) is used. In this version of the power lock sys-
tem, the power lock switches provide the only control
over the operation of the power lock motors. On mod-
els with the optional RKE system, a high-line or pre-
mium version of the CTM is used to provide many
electronic features and conveniences that are not pos-
sible with the base version CTM. In this power lock
system, the power lock motors are controlled by the
microprocessor-based high-line or premium version ofthe CTM based upon the CTM programming and
electronic message inputs received from other elec-
tronic modules in the vehicle over the Chrysler Col-
lision Detection (CCD) data bus network, Radio
Frequency (RF) inputs received from the RKE trans-
mitters, as well as many hard wired inputs.
Both versions of the power lock system include the
following major components, which are described in
further detail elsewhere in this service manual:
²Power Lock Motors- A reversible electric
motor integral to the door latch of each front door
locks or unlocks the front door latch when provided
with the appropriate electrical inputs.
²Power Lock Switches- A power lock switch
integral to the power window/lock switch unit located
near the forward end of the arm rest on each front
door trim panel allows the power door lock system to
be operated by either the driver or the front seat pas-
senger.
BR/BEPOWER SYSTEMS 8N - 1

OPERATION - POWER LOCK SYSTEM
All versions of the power lock system allow both
doors to be locked or unlocked electrically by operat-
ing the power lock switch on either front door trim
panel. On vehicles that are also equipped with the
optional Remote Keyless Entry (RKE) system, both
doors may also be locked or unlocked using a key in
either front door lock cylinder, or by using the RKE
transmitter. On vehicles with the RKE system, if cer-
tain features have been electronically enabled, the
locks may also be operated automatically by the
high-line or premium Central Timer Module (CTM)
based upon various other inputs. Those features and
their inputs are:
²Automatic Door Lock- If enabled, the high-
line/premium CTM will automatically lock the doors
when it receives a message from the Powertrain Con-
trol Module (PCM) indicating that the vehicle speed
is about 24 kilometers-per-hour (15 miles-per-hour)
or greater. The CTM also monitors the door ajar
switches, and will not activate the automatic door
lock feature until both doors have been closed for at
least five seconds. If this feature is enabled and a
door is opened after the vehicle is moving, the CTM
will also lock the doors five seconds after both doors
are closed.
²Central Locking- Vehicles equipped with a
high-line/premium CTM also have a resistor-multi-
plexed door cylinder lock switch mounted to the back
of the door lock cylinder within each front door. The
CTM continually monitors the input from these
switches to provide the central locking/unlocking fea-
ture. The CTM will automatically lock or unlock both
front doors when either front door is locked or
unlocked using a key.
²Door Lock Inhibit- The high-line/premium
CTM receives inputs from the key-in ignition switch,
the headlamp switch, and the door ajar switches. The
logic within the CTM allows it to monitor these
inputs to provide a door lock inhibit feature. The
door lock inhibit feature prevents the power lock sys-
tem from being energized with a power lock switch
input if the driver door is open with the headlamps
on or the key still in the ignition switch. However,
the locks can still be operated with the manual door
lock button or with a key in the door lock cylinder,
and the power locks will still operate using the RKE
transmitter while the driver door is open with the
headlamps on or a key in the ignition.
²Enhanced Accident Response- If enabled,
the high-line/premium CTM provides an enhanced
accident response feature. This feature uses elec-
tronic message inputs received by the CTM from the
Airbag Control Module (ACM) to determine when an
airbag has been deployed. The CTM also monitors
the state of the power lock system and the vehiclespeed messages from the PCM in order to provide
this feature. If the airbag has been deployed and the
vehicle has stopped moving, the CTM will automati-
cally unlock the doors, prevent the doors from being
locked, and turn on the courtesy lamps inside the
vehicle. Of course, these responses are dependent
upon a functional battery and electrical circuitry fol-
lowing the impact.
All versions of the power lock system operate on
battery current received through a fused B(+) circuit
from a fuse in the Junction Block (JB) so that the
system remains functional, regardless of the ignition
switch position. Also, in both versions of the power
lock system, each power lock switch receives battery
current independent of the other. In vehicles with the
base version of the power lock system, the driver side
power lock switch receives ground through the body
wire harness. A single wire take out of the body wire
harness with an eyelet terminal connector is secured
by a ground screw to the lower left B-pillar (regular
cab, extended cab) or lower left quarter inner panel
(quad cab). The passenger side power lock switch
receives ground through the driver side power lock
switch in the base version of the power lock system.
The base version power lock switches direct the
appropriate battery current and ground feeds to the
power lock motors. In the power lock system for vehi-
cles with the RKE system, the power lock switches
direct a battery current Lock or Unlock request sig-
nal to the high-line or premium CTM, and the CTM
energizes internal relays to direct the appropriate
battery current and ground feeds to the power lock
motors.
OPERATION - REMOTE KEYLESS ENTRY
SYSTEM
On vehicles with the Remote Keyless Entry (RKE)
system, the power locks can be operated remotely
using the RKE transmitter. If the vehicle is so
equipped, the RKE transmitter also arms and dis-
arms the factory-installed Vehicle Theft Security Sys-
tem (VTSS). Three small, recessed buttons on the
outside of the transmitter case labelled Lock, Unlock,
and Panic allow the user to choose the function that
is desired. The RKE transmitter then sends the
appropriate Radio Frequency (RF) signal. An RF
receiver that is integral to the high-line or premium
version of the Central Timer Module (CTM) receives
the transmitted signal, then uses its internal elec-
tronic programming to determine whether the
received signal is valid and what function has been
requested. If the signal is valid, the CTM provides
the programmed features.
Besides operating the power lock system and arm-
ing or disarming the VTSS, the RKE system also
controls the following features:
BR/BEPOWER LOCKS 8N - 3
POWER LOCKS (Continued)

²Horn Chirp- If this feature is enabled, the
CTM provides a horn chirp by internally pulling the
control coil of the horn relay to ground through a
hard wired circuit output.
²Illuminated Entry- The CTM provides illumi-
nated entry by internally controlling the current flow
to the courtesy lamps in the vehicle through a hard
wired output circuit.
²Panic Mode- The CTM provides the horn pulse
and headlight flash by internally pulling the control
coils of the horn relay and headlamp relay to ground
through hard wired circuit outputs. The CTM con-
trols the current flow to the courtesy lamps in the
vehicle through a hard wired output circuit. The
CTM also monitors the vehicle speed through elec-
tronic messages it receives from the Powertrain Con-
trol Module (PCM) over the Chrysler Collision
Detection (CCD) data bus network.
The RKE system operates on battery current received
through a fused B(+) circuit from a fuse in the Junction
Block (JB) so that the system remains functional,
regardless of the ignition switch position. The RKE sys-
tem can retain the vehicle access codes of up to four
RKE transmitters. The transmitter codes are retained
in RKE system memory, even if the battery is discon-
nected. If a transmitter is faulty or is lost, new trans-
mitter vehicle access codes can be programmed into the
system using a DRBIIItscan tool. Refer to the appro-
priate diagnostic information. Many of the electronic
features in the vehicle controlled or supported by the
high-line or premium versions of the CTM are program-
mable using the DRBIIItscan tool. In addition, the
high-line/premium CTM software is Flash compatible,
which means it can be reprogrammed using Flash
reprogramming procedures. However, if any of the CTM
hardware components are damaged or faulty, the entire
CTM unit must be replaced. The hard wired inputs or
outputs of the CTM can be diagnosed using conven-
tional diagnostic tools and methods; however, for diag-
nosis of the high-line or premium versions of the CTM
or the CCD data bus, the use of a DRBIIItscan tool is
required. Refer to the appropriate diagnostic informa-
tion.
DIAGNOSIS AND TESTING - POWER LOCK
SYSTEM
The following tests provide a preliminary diagnosis
for the power lock system usedonlyon vehicles
equipped with a base version of the Central Timer
Module (CTM). These testsdo notapply to the diag-
nosis of the power lock system used on vehicles
equipped with the optional Remote Keyless Entry
(RKE) system, which includes a high-line or premium
CTM. (Refer to 8 - ELECTRICAL/POWER LOCKS -
DIAGNOSIS AND TESTING - POWER LOCK &
REMOTE KEYLESS ENTRY SYSTEM). Refer to theappropriate 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.
PRELIMINARY TESTS
To begin this test, note the system operation while
you actuate both the Lock and Unlock functions with
the power lock switches. Then, proceed as follows:
²If the entire power lock system fails to function
with both of the power lock switches, check the fused
B(+) fuse in the Junction Block (JB). If the fuse is
OK, check the ground circuit between the driver side
power lock switch and ground (G301). If the ground
circuit is OK, proceed to the diagnosis of the power
lock motors. (Refer to 8 - ELECTRICAL/POWER
LOCKS/POWER LOCK MOTOR - DIAGNOSIS AND
TESTING).
²If the entire power lock system fails to function
with only one of the power lock switches, proceed to
diagnosis of the power lock switches. (Refer to 8 -
ELECTRICAL/POWER LOCKS/POWER LOCK
SWITCH - DIAGNOSIS AND TESTING).
²If only one power lock motor fails to operate
with both power lock switches, proceed to diagnosis
of the power lock motor. (Refer to 8 - ELECTRICAL/
POWER LOCKS/POWER LOCK MOTOR - DIAGNO-
SIS AND TESTING).
DIAGNOSIS AND TESTING - POWER LOCK &
REMOTE KEYLESS ENTRY SYSTEM
The following tests include a preliminary diagnosis
for the power lock system usedonlyon vehicles
equipped with the optional Remote Keyless Entry
(RKE) system, which includes a high-line or premium
Central Timer Module (CTM). These testsdo not
apply to the diagnosis of the power lock system on
vehicles equipped with a base version of the CTM.
(Refer to 8 - ELECTRICAL/POWER LOCKS - DIAG-
NOSIS AND TESTING - POWER LOCK SYSTEM).
These tests will help to diagnose the hard wired
components and circuits of the power lock system.
However, these tests may not prove conclusive in the
diagnosis of this system. In order to obtain conclusive
testing of the power lock and RKE system, the
Chrysler Collision Detection (CCD) data bus network
and all of the electronic modules that provide inputs
to, or receive outputs from the power lock and RKE
system components must be checked.
The most reliable, efficient, and accurate means to
diagnose the power lock and RKE system requires the
use of a DRBIIItscan tool. The DRBIIItscan tool can
provide confirmation that the CCD data bus is func-
tional, that all of the electronic modules are sending

DIAGNOSIS AND TESTING - POWER LOCK
MOTOR
On models with a base version of the Central
Timer Module (CTM), confirm proper power lock
switch operation before you proceed with this diagno-
sis. On models with a high-line or premium version
of the CTM, confirm proper power lock switch, power
lock switch output circuit, and CTM operation before
you proceed with this diagnosis. Remember, the
power lock switch controls the output to the power
lock motors on models with a base CTM, while the
CTM controls the output to the power lock motors on
models with a high-line or premium CTM. 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.
(1) Check each power lock motor for correct opera-
tion while moving the power lock switch to both the
Lock and Unlock positions. If both of the power lock
motors are inoperative, go to Step 2. If one power
lock motor is inoperative, go to Step 3.
(2) If both of the power lock motors are inopera-
tive, the problem may be caused by one shorted
motor. Disconnecting a shorted power lock motor
from the power lock circuit will allow the good power
lock motors to operate. Disconnect the wire harness
connector from each power lock motor, one at a time,
and recheck both the lock and unlock functions by
operating the power lock switch. If both power lock
motors are still inoperative after the above test,
check for a short or open circuit between the power
lock motors and either the power lock switch (base
CTM) or the CTM (high-line or premium CTM). If
disconnecting one power lock motor causes the other
motor to become functional, go to Step 3 to test the
disconnected motor.
(3) Once it is determined which power lock motor
is inoperative, that motor can be tested as follows.
Disconnect the door wire harness connector from the
inoperative power lock motor. Apply 12 volts to the
lock and unlock driver circuit cavities of the power
lock motor pigtail wire connector to check its opera-
tion in one direction. Reverse the polarity to check
the motor operation in the opposite direction. If OK,
repair the shorted or open circuits between the power
lock motor and the power lock switch (base CTM) or
the CTM (high-line or premium CTM) as required. If
not OK, replace the faulty power lock motor.
REMOTE KEYLESS ENTRY
TRANSMITTER
DESCRIPTION
The Remote Keyless Entry (RKE) system Radio
Frequency (RF) transmitter is equipped with three
buttons, labeled Lock, Unlock, and Panic. It is also
equipped with a key ring and is designed to serve as
a key fob. The operating range of the transmitter
radio signal is up to 7 meters (23 feet) from the RKE
receiver. The RKE receiver is integral to the high-
line or premium Central Timer Module (CTM) in this
vehicle.
Each RKE transmitter has a different vehicle
access code, which must be programmed into the
memory of the RKE receiver in the vehicle in order
to operate the RKE system. The RKE receiver can
retain the access codes for up to four transmitters in
its memory. (Refer to 8 - ELECTRICAL/POWER
LOCKS/REMOTE KEYLESS ENTRY TRANSMIT-
TER - STANDARD PROCEDURE - RKE TRANS-
MITTER PROGRAMMING).
The RKE transmitter operates on two Duracell
DL2016, Panasonic CR2016 (or equivalent) batteries.
Typical battery life is from one to two years. The
RKE transmitter cannot be repaired and, if faulty or
damaged, it must be replaced.
OPERATION
See the owner's manual in the vehicle glove box for
more information on the features, use and operation
of the Remote Keyless Entry (RKE) transmitters.
DIAGNOSIS AND TESTING - REMOTE KEYLESS
ENTRY TRANSMITTER
(1) Replace the Remote Keyless Entry (RKE)
transmitter batteries. (Refer to 8 - ELECTRICAL/
POWER LOCKS/REMOTE KEYLESS ENTRY
TRANSMITTER - STANDARD PROCEDURE - RKE
TRANSMITTER BATTERIES). Test each of the RKE
transmitter functions. If OK, discard the faulty bat-
teries. If not OK, go to Step 2.
(2) Program the suspect RKE transmitter and
another known good transmitter into the RKE
receiver. (Refer to 8 - ELECTRICAL/POWER
LOCKS/REMOTE KEYLESS ENTRY TRANSMIT-
TER - STANDARD PROCEDURE - RKE TRANS-
MITTER PROGRAMMING).
(3) Test the RKE system operation with both
transmitters. If both transmitters fail to operate the
power lock system, a DRBIIItscan tool is required
for further diagnosis of the RKE system. Refer to the
appropriate diagnostic information. If the known
good RKE transmitter operates the power locks and

the suspect transmitter does not, replace the faulty
RKE transmitter.
NOTE: Be certain to perform the RKE Transmitter
Programming procedure again following this test.
This procedure will erase the access code of the
test transmitter from the RKE receiver.
STANDARD PROCEDURE - RKE TRANSMITTER
PROGRAMMING
To program the Remote Keyless Entry (RKE)
transmitter access codes into the RKE receiver in the
high-line or premium Central Timer Module (CTM)
requires the use of a DRBIIItscan tool. Refer to the
appropriate diagnostic information.
STANDARD PROCEDURE - RKE TRANSMITTER
BATTERIES
The Remote Keyless Entry (RKE) transmitter case
snaps open and shut for battery access. To replace
the RKE transmitter batteries:
(1) Using a trim stick or a thin coin, gently pry at
the notch in the center seam of the RKE transmitter
case halves located near the key ring until the two
halves unsnap.
(2) Lift the back half of the transmitter case off of
the RKE transmitter.
(3) Remove the two batteries from the RKE trans-
mitter.
(4) Replace the two batteries with new Duracell
DL2016, or their equivalent. Be certain that the bat-
teries are installed with their polarity correctly ori-
ented.
(5) Align the two RKE transmitter case halves
with each other, and squeeze them firmly and evenly
together using hand pressure until they snap back
into place.
POWER LOCK SWITCH
DESCRIPTION
The power lock system can be controlled by a two-
way momentary switch integral to the power window
and lock switch and bezel unit on the trim panel of
each front door. Each power lock switch is illumi-
nated by a Light-Emitting Diode (LED) that is inte-
gral to the switch paddle. The LED of each switch is
illuminated whenever the ignition switch is in the
On position.
The power lock switches and their LEDs cannot be
adjusted or repaired and, if faulty or damaged, the
entire power window and lock switch and bezel unit
must be replaced.
OPERATION
On models with a base version of the Central
Timer Module (CTM), the power lock switches are
hard-wired to the power lock motors. The power lock
switch provides the correct battery and ground feeds
to the power lock motors to lock or unlock the door
latches.
On models with a high-line or premium version of
the CTM, the power lock switch controls battery cur-
rent signals to the lock and unlock sense inputs of
the CTM. The CTM then relays the correct battery
and ground feeds to the power lock motors to lock or
unlock the door latches.
DIAGNOSIS AND TESTING - POWER LOCK
SWITCH
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 (JB). If all of the LEDs are inopera-
tive in either or both power window and lock switch
and bezel units, be certain to diagnose the power
window system before replacing the switch unit.
(Refer to 8 - ELECTRICAL/POWER WINDOWS -
DIAGNOSIS AND TESTING). If only one LED in a
power window and lock switch and bezel unit is inop-
erative, replace the faulty switch and bezel unit.
Refer to the appropriate wiring information. The wir-
ing 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.
(1) Check the fused B(+) fuse (Fuse 13 - 10
ampere) in the Junction Block (JB). If OK, go to Step
2. If not OK, repair the shorted circuit or component
as required and replace the faulty fuse.
(2) Check for battery voltage at the fused B(+) fuse
(Fuse 13 - 10 ampere) in the JB. If OK, go to Step 3.
If not OK, repair the open fused B(+) circuit between
the JB and the Power Distribution Center (PDC) as
required.
(3) Disconnect and isolate the battery negative
cable. Remove the power window and lock switch and
bezel unit from the door trim panel. Disconnect the
door wire harness connector for the power window
and lock switch unit from the switch connector recep-
tacle.
(4) Reconnect the battery negative cable. Check for
battery voltage at the fused B(+) circuit cavity of the
door wire harness connector for the power window
and lock switch unit. If OK, go to Step 5. If not OK,
repair the open fused B(+) circuit between the power
window and lock switch unit and the JB as required.

CLOSURE PANEL TRIM - INSTALLATION).
CLOCKSPRING
DESCRIPTION
The clockspring assembly is secured with two inte-
gral plastic latches onto the steering column lock
housing near the top of the steering column, behind
the steering wheel. The clockspring consists of a flat,
round molded plastic case with a stubby tail that
hangs below the steering column and contains a con-
nector receptacle and a long pigtail wire with connec-
tor that face toward the instrument panel. Within
the plastic housing is a spool-like molded plastic
rotor with a large exposed hub. The upper surface of
the rotor hub has a large center hole, two large flats,
two auto-locking tabs, and three short pigtail wires
with connectors that face toward the steering wheel.
The lower surface of the rotor hub has two integral
turn signal cancelling cam lobes. Within the plastic
case and wound around the rotor spool is a long rib-
bon-like tape that consists of several thin copper wire
leads sandwiched between two thin plastic mem-
branes. The outer end of the tape terminates at the
connector receptacle and pigtail wire that face the
instrument panel, while the inner end of the tape
terminates at the pigtail wires on the hub of the
clockspring rotor that face the steering wheel.
Service replacement clocksprings are shipped pre-
centered and with a piece of tape covering the
engaged auto-locking tabs. The auto-locking tabs
secure the centered clockspring rotor to the clock-
spring case during shipment, but these tabs are auto-
matically disengaged once the clockspring is installed
on the steering column. (Refer to 8 - ELECTRICAL/
RESTRAINTS/CLOCKSPRING - STANDARD PRO-
CEDURE - CLOCKSPRING CENTERING).
The clockspring cannot be repaired. If the clock-
spring is faulty, damaged, or if the driver airbag has
been deployed, the clockspring must be replaced.
OPERATION
The clockspring is a mechanical electrical circuit
component that is used to provide continuous electri-
cal continuity between the fixed instrument panel
wire harness and the electrical components mountedon or in the rotating steering wheel. On this model
the rotating electrical components include the driver
airbag, the horn switch, the speed control switches,
and the remote radio switches if the vehicle is so
equipped. The clockspring case is positioned and
secured to the upper steering column lock housing by
two integral plastic latches. The connector receptacle
on the tail of the fixed clockspring housing connect
the clockspring to the vehicle electrical system
through a take out with connector from the instru-
ment panel wire harness. The lower clockspring pig-
tail on the tail of the clockspring housing connect the
clockspring driver airbag circuits to a separate take
out and connector of the instrument panel wire har-
ness located near the lower instrument panel rein-
forcement, below the steering column. The
clockspring rotor is movable and is keyed to the hub
of the steering wheel by two large flats that are
molded into the rotor hub. The two lobes on the
lower surface of the clockspring rotor hub contact a
turn signal cancel actuator of the multi-function
switch to provide automatic turn signal cancellation.
The pigtail wires on the upper surface of the clock-
spring connect the clockspring to the horn switch, the
two speed control switches, and the remote radio
switches on vehicles that are so equipped.
Like the clockspring in a timepiece, the clockspring
tape has travel limits and can be damaged by being
wound too tightly during full stop-to-stop steering
wheel rotation. To prevent this from occurring, the
clockspring must be centered when it is installed on
the steering column. Centering the clockspring
indexes the clockspring spool to the movable steering
components so that the tape can operate within its
designed travel limits. However, if the clockspring is
removed from the steering column or if the steering
shaft is disconnected from the steering gear, the
clockspring spool can change position relative to the
movable steering components and must be re-cen-
tered following completion of the service or the tape
may be damaged. Service replacement clocksprings
are shipped pre-centered and with the auto-locking
tabs engaged. A piece of tape covers the auto-locking
tabs to discourage tampering. These auto-locking
tabs should not be disengaged until the clockspring
has been installed on the steering column. If this
shipping tape is removed or damaged, or if the auto-
locking tabs are disengaged before the clockspring is
installed on a steering column, the clockspring cen-
tering procedure must be performed. (Refer to 8 -
ELECTRICAL/RESTRAINTS/CLOCKSPRING -
STANDARD PROCEDURE - CLOCKSPRING CEN-
TERING).
8O - 10 RESTRAINTSBR/BE
CHILD TETHER (Continued)

STANDARD PROCEDURE - CLOCKSPRING
CENTERING
The clockspring is designed to wind and unwind
when the steering wheel is rotated, but is only
designed to rotate the same number of turns (about
five complete rotations) as the steering wheel can be
turned from stop to stop. Centering the clockspring
indexes the clockspring tape to other steering compo-
nents so that it can operate within its designed
travel limits. The rotor of a centered clockspring can
be rotated two and one-half turns in either direction
from the centered position, without damaging the
clockspring tape.
However, if the clockspring is removed for service
or if the steering column is disconnected from the
steering gear, the clockspring tape can change posi-
tion relative to the other steering components. The
clockspring must then be re-centered following com-
pletion of such service or the clockspring tape may be
damaged. Service replacement clocksprings are
shipped pre-centered and with the auto-locking tabs
engaged (raised). These auto-locking tabs should not
be disengaged until the clockspring has been
installed on the steering column. If the auto-locking
tabs are disengaged before the clockspring is
installed on a steering column, the clockspring cen-
tering procedure must be performed.

travel.Do not apply excessive torque.
(5) From the end of the clockwise travel, rotate the
rotor about two and one-half turns counterclockwise,
then release the auto-locking tabs. The clockspring
pigtail wire for the horn switch should end up at the
top, and the pigtail wires for the airbag, optional
speed control switches, and optional remote radio
switches at the bottom. The clockspring is now cen-
tered.
(6) The front wheels should still be in the straight-
ahead position. Reinstall the clockspring onto the
steering column. (Refer to 8 - ELECTRICAL/RE-

VEHICLE THEFT SECURITY
DESCRIPTION
The Vehicle Theft Security System (VTSS) is an
available factory-installed option on this model when
it is also equipped with the high-line or premium
Central Timer Module (CTM). The VTSS is designed
to provide perimeter protection against unauthorized
use or tampering by monitoring the vehicle doors and
the ignition system. If unauthorized vehicle use or
tampering is detected, the system responds by puls-
ing the horn, flashing the headlamps, and preventing
the engine from operating.
The VTSS includes the following major compo-
nents, which are described in further detail else-
where in this service manual:
²Central Timer Module- The high-line or pre-
mium Central Timer Module (CTM) is located under
the driver side end of the instrument panel, inboard
of the instrument panel steering column opening.
The high-line or premium CTM contains a micropro-
cessor and software that allow it to provide many
electronic functions and features not available with
base version of the CTM, including the VTSS. The
CTM provides all of the proper VTSS features and
outputs based upon the monitored inputs. The CTM
circuitry monitors hard wired switch inputs, as well
as message inputs received from other vehicle elec-
tronic modules over the Chrysler Collision Detection
(CCD) data bus network. (Refer to 8 - ELECTRICAL/
ELECTRONIC CONTROL MODULES/BODY CON-
TROL/CENTRAL TIMER MODULE -
DESCRIPTION).
²Door Ajar Switch- A door ajar switch is
located on the hinge pillar of each front door in the
vehicle. These switches provide an input to the VTSS
indicating whether the door is opened or closed.
(Refer to 8 - ELECTRICAL/LAMPS/LIGHTING -
INTERIOR/DOOR AJAR SWITCH - DESCRIPTION).
²Door Cylinder Lock Switch- A door cylinder
lock switch is located on the back of each front door
lock cylinder. This switch provides an input to theVTSS indicating whether the system should remain
armed or be disarmed. (Refer to 8 - ELECTRICAL/
POWER LOCKS/DOOR CYLINDER LOCK SWITCH
- DESCRIPTION).
²Horn Relay- The horn relay is located in the
Power Distribution Center (PDC) in the engine com-
partment near the battery. The horn relay is nor-
mally activated by the horn switch to control the
sounding of the vehicle horn or horns. However, it
can also be activated by an output of the Central
Timer Module (CTM) to provide an audible indication
that unauthorized vehicle use or tampering has been
detected. (Refer to 8 - ELECTRICAL/HORN/HORN
RELAY - DESCRIPTION).
²Headlamp Relay- The headlamp relay (also
known as the security relay) is located in the Power
Distribution Center (PDC) in the engine compart-
ment near the battery. The headlamp relay is nor-
mally activated by the Central Timer Module (CTM)
based upon inputs from the Remote Keyless Entry
(RKE) panic mode feature. However, it can also be
activated by an output of the CTM to flash the head-
lamp low beams to provide a highly visible indication
that unauthorized vehicle use or tampering has been
detected. (Refer to 8 - ELECTRICAL/LAMPS/LIGHT-
ING - EXTERIOR/HEADLAMP RELAY - DESCRIP-
TION).
²VTSS Indicator- A red Light Emitting Diode
(LED) located on the lower surface of the overhead
console near the windshield is illuminated by an out-
put of the Central Timer Module (CTM) to indicate
the status of the VTSS. This LED is integral to the
electronic circuit board for the Compass Mini-Trip
Computer (CMTC). (Refer to 8 - ELECTRICAL/
OVERHEAD CONSOLE/COMPASS/MINI-TRIP
COMPUTER - DESCRIPTION).
The engine no-run feature of the VTSS relies upon
communication between the high-line or premium
CTM and the Powertrain Control Module (PCM) over
the Chrysler Collision Detection (CCD) data bus net-
work.
Hard wired circuitry connects many of the VTSS
components to each other through the electrical sys-
