SWITCH
DESCRIPTION
Gas Engines and Diesel With Auto. Trans.
There are two separate switch pods that operate
the speed control system. The steering-wheel-
mounted switches use multiplexed circuits to provideinputs to the Powertrain Control Module (PCM) for
ON, OFF, RESUME, ACCELERATE, SET, DECEL
and CANCEL modes. Refer to the owner's manual for
more information on speed control switch functions
and setting procedures.
The individual switches cannot be repaired. If one
switch fails, the entire switch module must be
replaced.
Diesel With Manual Trans.
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 Engine Control Module (ECM) for ON,
OFF, RESUME, ACCELERATE, SET, DECEL and
CANCEL modes. Refer to the owner's manual for
more information on speed control switch functions
and setting procedures.
The individual switches cannot be repaired. If one
switch fails, the entire switch module must be
replaced.
OPERATION
Gas Engines and Diesel With Auto. Trans.
When speed control is selected by depressing the
ON, OFF switch, the Powertrain Control Module
(PCM) allows a set speed to be stored in its RAM for
speed control. To store a set speed, depress the SET
switch while the vehicle is moving at a speed
between approximately 35 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.
The speed control can be disengaged also by any of
the following conditions:
²An indication of Park or Neutral.
²The vehicle speed 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).
²Depressing the clutch pedal.
²Excessive engine rpm (indicates that the trans-
mission may be in a low gear).
²The vehicle speed 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.

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.

the wiper blade with a new unit. Do not attempt to
repair a wiper blade that is damaged.
WASHER SYSTEM
The washer system components should be
inspected periodically, not just when washer perfor-
mance problems are experienced. This inspection
should include the following points:
(1) Check for ice or other foreign material in the
washer reservoir. If contaminated, clean and flush
the washer system. (Refer to 8 - ELECTRICAL/WIP-
ERS/WASHERS - CLEANING).
(2) Inspect the washer plumbing for pinched, leak-
ing, deteriorated, or incorrectly routed hoses and
damaged or disconnected hose fittings. Replace dam-
aged or deteriorated hoses and hose fittings. Leaking
washer hoses can sometimes be repaired by cutting
the hose at the leak and splicing it back together
using an in-line connector fitting. Similarly, sections
of deteriorated hose can be cut out and replaced by
splicing in new sections of hose using in-line connec-
tor fittings. Whenever routing a washer hose or a
wire harness containing a washer hose, it must be
routed away from hot, sharp, or moving parts. Also,sharp bends that might pinch the washer hose must
be avoided.
WASHER FLUID LEVEL
SWITCH
DESCRIPTION
The washer fluid level switch is a single pole, sin-
gle throw reed-type switch mounted on the rear of
the washer reservoir above the washer pump/motor,
in the left front corner of the engine compartment.
Only the molded plastic switch mounting flange and
connector receptacle are visible when the switch is
installed in the reservoir. A short nipple formation
extends from the inner surface of the switch mount-
ing flange, and a barb on the nipple near the switch
mounting flange is press-fit into a rubber grommet
seal installed in the mounting hole of the reservoir. A
small plastic float pivots on the end of a bracket that
extends from the switch nipple formation. Within the
float is a small magnet, which actuates the reed
switch. The washer fluid level switch cannot be
adjusted or repaired. If faulty or damaged, the switch
must be replaced.
OPERATION
The washer fluid level switch uses a pivoting,
oblong float to monitor the level of the washer fluid
in the washer reservoir. The float contains a small
magnet. When the float pivots, the changing proxim-
ity of its magnetic field will cause the contacts of the
small, stationary reed switch to open or close. When
the fluid level in the washer reservoir is at or above
the float level, the float moves to a vertical position
and the switch contacts open. When the fluid level in
the washer reservoir falls below the pivoting float,
the float moves to a horizontal position and the
switch contacts close. The switch contacts are con-
nected in series between ground and the washer fluid
switch sense input of the instrument cluster. The
switch is connected to the vehicle electrical system
through a dedicated take out and connector of the
headlamp and dash wire harness. The switch
receives ground through another take out of the
headlamp and dash wire harness with a single eyelet
terminal connector that is secured under a nut to a
ground stud located on the front extension of the left
front wheel housing in the engine compartment. The
washer fluid level switch can be diagnosed using con-
ventional diagnostic tools and methods. (Refer to 8 -

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

POWER OUTLET
DESCRIPTION
Two power outlets are installed in the vehicle. One
in the instrument panel next to the cigar lighter and
the other in the right rear quarter trim panel. The
power outlet bases are secured by a snap fit within
the instrument panel or trim panel. A plastic protec-
tive cap snaps into the power outlet base when the
power outlet is not being used, and hangs from the
power outlet base mount by an integral bail strap
while the power outlet is in use.
The power outlet receptacle unit and the accessory
power outlet protective cap are available for service.
The power outlet receptacle cannot be repaired and,
if faulty or damaged, it must be replaced.
OPERATION
The power outlet base or receptacle shell is con-
nected to ground, and an insulated contact in the
bottom of the shell is connected to battery current.
The power outlet receives battery voltage from a fuse
in the Junction Block at all times.
While the power outlet is very similar to a cigar
lighter base unit, it does not include the two small
spring-clip retainers inside the bottom of the recepta-
cle shell that are used to secure the cigar lighter
heating element to the insulated contact.
DIAGNOSIS AND TESTING - POWER OUTLET
For complete circuit diagrams, refer toPower
Outletin Wiring Diagrams.
(1) Check the fused B(+) fuse in the junction block.
If OK, go to Step 2. If not OK, repair the shorted cir-
cuit or component as required and replace the faulty
fuse.
(2) Check for battery voltage at the fused B(+) fuse
in the junction block. If OK, go to Step 3. If not OK,
repair the open fused B(+) circuit to the battery as
required.
(3) Remove the plastic protective cap from the
power outlet receptacle. Check for continuity between
the inside circumference of the power outlet recepta-
cle and a good ground. There should be continuity. If
OK, go to Step 4. If not OK, go to Step 5.
(4) Check for battery voltage at the insulated con-
tact located at the back of the power outlet recepta-
cle. If not OK, go to Step 5.
