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.
BR/BEVEHICLE THEFT SECURITY 8Q - 1

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-
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
DRBIIItscan tool. Refer to the appropriate diagnos-
tic information. The DRBIIItscan 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 theproper hard wired outputs needed to perform their
functions. See the ªVehicle Theft Security Systemº
menu item on the DRBIIItscan tool.
WARNING: ON VEHICLES EQUIPPED WITH AIR-
BAGS, DISABLE THE AIRBAG SYSTEM BEFORE
ATTEMPTING ANY STEERING WHEEL, STEERING
COLUMN, OR INSTRUMENT PANEL COMPONENT
DIAGNOSIS OR SERVICE. DISCONNECT AND ISO-
LATE THE BATTERY NEGATIVE (GROUND) CABLE,
THEN WAIT TWO MINUTES FOR THE AIRBAG SYS-
TEM CAPACITOR TO DISCHARGE BEFORE PER-
FORMING FURTHER DIAGNOSIS OR SERVICE. THIS
IS THE ONLY SURE WAY TO DISABLE THE AIRBAG
SYSTEM. FAILURE TO TAKE THE PROPER PRE-
CAUTIONS COULD RESULT IN ACCIDENTAL AIR-
BAG DEPLOYMENT AND POSSIBLE PERSONAL
INJURY.
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.

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.

DIAGNOSIS AND TESTING - WIRING HARNESS
TROUBLESHOOTING TOOLS
When diagnosing a problem in an electrical circuit
there are several common tools necessary. These tools
are listed and explained below.
²Jumper Wire - This is a test wire used to con-
nect two points of a circuit. It can be used to bypass
an open in a circuit.WARNING: NEVER USE A JUMPER WIRE ACROSS
A LOAD, SUCH AS A MOTOR, CONNECTED
BETWEEN A BATTERY FEED AND GROUND.
²Voltmeter - Used to check for voltage on a cir-
cuit. Always connect the black lead to a known good
ground and the red lead to the positive side of the
circuit.
CAUTION: Most of the electrical components used
in today's vehicles are Solid State. When checking
voltages in these circuits, use a meter with a 10 -
megohm or greater impedance rating.
²Ohmmeter - Used to check the resistance
between two points of a circuit. Low or no resistance
in a circuit means good continuity.
CAUTION: Most of the electrical components used
in today's vehicles are Solid State. When checking
resistance in these circuits use a meter with a 10 -
megohm or greater impedance rating. In addition,
make sure the power is disconnected from the cir-
cuit. Circuits that are powered up by the vehicle's
electrical system can cause damage to the equip-
ment and provide false readings.
²Probing Tools - These tools are used for probing
terminals in connectors (Fig. 5). Select the proper
size tool from Special Tool Package 6807, and insert
it into the terminal being tested. Use the other end
of the tool to insert the meter probe.
INTERMITTENT AND POOR CONNECTIONS
Most intermittent electrical problems are caused
by faulty electrical connections or wiring. It is also
possible for a sticking component or relay to cause a
problem. Before condemning a component or wiring
assembly, check the following items.
²Connectors are fully seated
²Spread terminals, or terminal push out

HYDRAULIC LIFTERS
DIAGNOSIS AND TESTINGÐHYDRAULIC
TAPPETS
Before disassembling any part of the engine to cor-
rect tappet noise, check the oil pressure. If vehicle
has no oil pressure gauge, install a reliable gauge at
the pressure sending-unit. The pressure should be
between 207-552 kPa (30-80 psi) at 3,000 RPM.
Check the oil level after the engine reaches normal
operating temperature. Allow 5 minutes to stabilize
oil level, check dipstick. The oil level in the pan
should never be above the FULL mark or below the
ADD OIL mark on dipstick. Either of these two con-
ditions could be responsible for noisy tappets.
OIL LEVEL
HIGH
If oil level is above the FULL mark, it is possible
for the connecting rods to dip into the oil. With the
engine running, this condition could create foam in
the oil pan. Foam in oil pan would be fed to the
hydraulic tappets by the oil pump causing them to
lose length and allow valves to seat noisily.
LOW
Low oil level may allow oil pump to take in air.
When air is fed to the tappets, they lose length,
which allows valves to seat noisily. Any leaks on
intake side of oil pump through which air can be
drawn will create the same tappet action. Check the
lubrication system from the intake strainer to the
pump cover, including the relief valve retainer cap.
When tappet noise is due to aeration, it may be
intermittent or constant, and usually more than one
tappet will be noisy. When oil level and leaks have
been corrected, operate the engine at fast idle. Run
engine for a sufficient time to allow all of the air
inside the tappets to be bled out.
TAPPET NOISE DIAGNOSIS
(1) To determine source of tappet noise, operate
engine at idle with cylinder head covers removed.
(2) Feel each valve spring or rocker arm to detect
noisy tappet. The noisy tappet will cause the affected
spring and/or rocker arm to vibrate or feel rough in
operation.
NOTE: Worn valve guides or cocked springs are
sometimes mistaken for noisy tappets. If such is
the case, noise may be dampened by applying side
thrust on the valve spring. If noise is not apprecia-
bly reduced, it can be assumed the noise is in the
tappet. Inspect the rocker arm push rod sockets
and push rod ends for wear.
(3)
Valve tappet noise ranges from light noise to a
heavy click. A light noise is usually caused by exces-
sive leak-down around the unit plunger, or by the
plunger partially sticking in the tappet body cylinder.
The tappet should be replaced. A heavy click is caused
by a tappet check valve not seating, or by foreign par-
ticles wedged between the plunger and the tappet
body. This will cause the plunger to stick in the down
position. This heavy click will be accompanied by
excessive clearance between the valve stem and rocker
arm as valve closes. In either case, tappet assembly
should be removed for inspection and cleaning.
(4) The valve train generates a noise very much
like a light tappet noise during normal operation.
Care must be taken to ensure that tappets are mak-

tappets, which pass oil through hollow push rods to a
hole in the corresponding rocker arm. Oil from the
rocker arm lubricates the valve train components.The oil then passes down through the push rod guide
holes and the oil drain-back passages in the cylinder
head, past the valve tappet area, and then returns to
the oil pan (Fig. 49).
DIAGNOSIS AND TESTING
DIAGNOSIS AND TESTINGÐENGINE OIL
LEAKS
Begin with a through visual inspection of the
engine, particularly at the area of the suspected leak.
If an oil leak source is not readily identifiable, the
following steps should be followed:
(1) Do not clean or degrease the engine at this
time because some solvents may cause rubber to
swell, temporarily stopping the leak.
(2) Add an oil-soluble dye (use as recommended by
manufacturer). Start the engine and let idle for
approximately 15 minutes. Check the oil dipstick to
be sure the dye is thoroughly mixed as indicated
with a bright yellow color under a black light source.
(3) Using a black light, inspect the entire engine
for fluorescent dye, particularly at the suspected area
of oil leak. If the oil leak is found and identified,
repair per service manual instructions.

(15) Remove intake manifold bolts.
(16) Lift the intake manifold and throttle body out
of the engine compartment as an assembly.
(17) Remove and discard the flange side gaskets
and the front and rear end seals.
(18) Remove the throttle body bolts and lift the
throttle body off the intake manifold (Fig. 65). Dis-
card the gasket.
(19) If required, remove the plenum pan and gas-
ket. Discard gasket.
CLEANING
Clean manifold in solvent and blow dry with com-
pressed air.
Clean cylinder block front and rear gasket surfaces
using a suitable solvent.
The plenum pan rail must be clean and dry (free of
all foreign material).
INSPECTION
Inspect manifold for cracks.
Inspect mating surfaces of manifold for flatness
with a straightedge.
INSTALLATION
(1) If removed, position new plenum gasket and
install plenum pan (Fig. 66).
(2) Tighten plenum pan mounting bolts as follows:²Step 1. Tighten bolts to 5.4 N´m (48 in. lbs.)
²Step 2. Tighten bolts to 9.5 N´m (84 in. lbs.)
²Step 3. Check all bolts are at 9.5 N´m (84 in.
lbs.)
(3) Install the flange gaskets. Ensure that the ver-
tical port alignment tab is resting on the deck face of
the block. Also the horizontal alignment tabs must be
in position with the mating cylinder head gasket tabs
(Fig. 68). The words MANIFOLD SIDE should be vis-
ible on the center of each flange gasket.
(4) Apply MopartGEN II Silicone Rubber Adhe-
sive Sealant, or equivalent, to the four corner joints.
An excessive amount of sealant is not required to
ensure a leak proof seal. However, an excessive
amount of sealant may reduce the effectiveness of
the flange gasket. The sealant should be approxi-
mately 5 mm (0.2 in) in diameter and 15 mm (0.6 in.)
long.
(5) Install the front and rear end seals (Fig. 67)
Make sure the molded dowel pins on the end seals
fully enter the corresponding holes in the cylinder
block.
(6) Carefully lower intake manifold into position
on the cylinder block and cylinder heads. After intake
manifold is in place, inspect to make sure seals are
in place.
