READING LAMP
DESCRIPTION
The overhead console in this vehicle is equipped
with two individual reading and courtesy lamps. The
lamp lenses are the only visible components of these
lamps. The reading and courtesy lamp lenses are
mounted in the overhead console housing between
the garage door opener storage bin and the sun-
glasses storage bin. Each lamp has its own switch,
bulb, reflector and lens; but both lamps share a com-
mon lamp housing within the overhead console.
The overhead console reading and courtesy lamps
operate on battery current that is provided at all
times, regardless of the ignition switch position. The
ground feed for the lamps is switched through the
integral reading and courtesy lamp switches or
through the door jamb switches. Each lamp is
designed and aimed to provide illumination that will
be directed only to that side of the vehicle on which
the lamp is located.
The reading and courtesy lamp lenses, bulbs and
the lamp housing and reflector unit are available for
service replacement. The reading and courtesy lamp
switches, bulb holders and wiring are only available
as part of the overhead console wire harness. If
either of the lamp switches or bulb holders is faulty
or damaged, the entire overhead console wire har-
ness assembly must be replaced.
For service of the reading and courtesy lamp bulbs,
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.
OPERATION
All reading and courtesy lamps located in the over-
head console are activated by the door jamb switches.
When all of the doors are closed, these lamps can be
individually activated by depressing the correspond-
ing lens. When any door is open, depressing the lamp
lenses to activate the lamp switches will not turn the
lamps off.
See the owner's manual in the vehicle glove box for
more information on the use and operation of the
overhead console reading and courtesy lamps.

Compass mini-trip computer units for vehicles
equipped with the VTSS include a red Light-Emit-
ting Diode (LED) on their electronic circuit board.
This LED protrudes through the bottom of the lens
on the front of the overhead console unit, and serves
as the security indicator lamp. Refer toSecurity
Indicator Lampin Vehicle Theft/Security Systems
for more information on this feature.
The compass mini-trip computer module contains a
central processing unit and interfaces with other
electronic modules in the vehicle on the Chrysler Col-
lision Detection (CCD) data bus network. The CCD
data bus network allows the sharing of sensor infor-
mation. This helps to reduce wire harness complexity,
reduce internal controller hardware, and reduce com-
ponent sensor current loads. At the same time, this
system provides increased reliability, enhanced diag-
nostics, and allows the addition of many new feature
capabilities.
The compass mini-trip computer provides several
electronic functions and features. Some of the func-
tions and features that the compass mini-trip com-
puter module supports and/or controls, include the
following display options:
²Compass and temperature- provides the out-
side temperature and one of eight compass readings
to indicate the direction the vehicle is facing.
²Compass and compass in degrees- provides
one of eight compass readings to indicate the direc-
tion the vehicle is facing and provides the compass
direction in degrees.
²Trip odometer (ODO)- shows the distance
travelled since the last trip computer reset.
²Average fuel economy (AVG ECO)- shows
the average fuel economy since the last trip computer
reset.
²Instant fuel economy (ECO)- shows the
present fuel economy based upon the current vehicle
distance and fuel used information.
²Distance to empty (DTE)- shows the esti-
mated distance that can be travelled with the fuel
remaining in the fuel tank. This estimated distance
is computed using the average miles-per-gallon from
the last 30 gallons of fuel used.
²Elapsed time (ET)- shows the accumulated
ignition-on time since the last trip computer reset.
²Blank screen- the compass mini-trip VFD is
turned off.
The ambient temperature sensor is hard wired to
the compass mini-trip computer module. Data input
for all other compass mini-trip computer functions,
including VFD dimming level, is received through
CCD data bus messages. The compass mini-trip com-
puter uses its internal programming and all of these
inputs to calculate and display the requested data. If
the data displayed is incorrect, perform the self-diag-nostic tests as described in this group. If these tests
prove inconclusive, the use of a DRBIIItscan tool
and the proper Diagnostic Procedures manual are
recommended for further testing of the compass
mini-trip computer module and the CCD data bus.
The compass mini-trip computer module cannot be
repaired, and is available for service only as a unit. If
faulty or damaged, the complete module must be
replaced.
OPERATION
The compass mini-trip computer only operates with
the ignition switch in the On position. When the igni-
tion switch is turned to the On position, all of the
segments in the compass mini-trip computer VFD
will be turned on for one second, then the display
will return to the last function being displayed before
the ignition was turned to the Off position. With the
ignition switch in the On position, momentarily
depressing and releasing the Step push button switch
will cause the compass-mini-trip computer to change
its mode of operation, and momentarily depressing
and releasing the U.S./Metric push button will cause
the unit to toggle between U.S. and Metric measure-
ments. While in either compass mode, depressing the
U.S./Metric push button for more than ten seconds
will toggle the display between the compass/temper-
ature and the compass/compass in degrees modes.
This compass mini-trip computer features several
functions that can be reset. If both the Step and U.S./
Metric push buttons are depressed at the same time
with the ignition switch in the On position, the trip
computer information that can be reset is reset.
Depressing and releasing the Step and U.S./Metric
push buttons at the same time for more than 100
milliseconds, but not more than one second while in
any display mode (except the compass/temperature
mode) will cause a local reset. A local reset affects
only the function currently displayed. See the Reset
Chart below for more information on this feature.
Performing a local reset while in the compass/tem-
perature mode enters the module into the compass
variance setting mode.
Depressing and releasing the Step and U.S./Metric
push buttons at the same time for more than two
seconds while in any display mode (except the com-
pass/temperature mode) will cause a global reset. A
global reset changes all of the trip computer func-
tions that can be reset.
For more information on the features and control
functions of the compass mini-trip computer, see the
owner's manual in the vehicle glove box.

²Microprocessor ROM verification test
²CCD communications test.
(4) Following completion of these tests, the com-
pass mini-trip computer will display one of three
messages: ªPASS,º ªFAIL,º or ªCCd.º Respond to the
respective test results as follows:
²If the ªPASSº message is displayed, but compass
mini-trip computer operation is still improper, the
use of a DRB scan tool and the proper Diagnostic
Procedures manual are required for further diagno-
sis.
²If the ªFAILº message is displayed, the compass
mini-trip computer module is faulty and must be
replaced.
²If the ªCCdº message is displayed, the use of a
DRBtscan tool and the proper Diagnostic Proce-
dures manual are required for further diagnosis.
²If any VFD segment should fail to light during
the display segment test, the compass mini-trip com-
puter module is faulty and must be replaced.

COMPASS/MINI-TRIP COMPUTER (Continued)

On those models equipped with the optional RKE
system, the power lock system also includes the fol-
lowing components, which are described in further
detail elsewhere 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 the many
electronic functions and features not available with
base version of the power lock system.
²Door Cylinder Lock Switches- A resistor-
multiplexed switch located on the back of each front
door lock cylinder allows the power door lock system
to be operated using a key inserted in either the
driver or passenger front door lock cylinder.
Some of the additional features of the power lock
system found in vehicles with the RKE system option
include:
²Automatic Door Lock- The high-line/premium
CTM provides an optional automatic door lock fea-
ture (also known as rolling door locks). This is a pro-
grammable feature.
²Central Locking- The high-line/premium CTM
provides an optional central locking/unlocking fea-
ture.
²Door Lock Inhibit- The high-line/premium
CTM provides a door lock inhibit feature.
²Enhanced Accident Response- The high-line/
premium CTM provides an optional enhanced acci-
dent response feature. This is a programmable
feature.
Hard wired circuitry connects the power lock sys-
tem components to the electrical system of the vehi-
cle. These hard wired circuits are integral to several
wire harnesses, which are routed throughout the
vehicle and retained by many different methods.
These circuits may be connected to each other, to the
vehicle electrical system and to the power lock sys-
tem 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.
Many of the electronic features in the vehicle con-
trolled or supported by the high-line or premium ver-
sions of the CTM are programmable using the
DRBIIItscan tool. In addition, the high-line/pre-
mium CTM software is Flash compatible, which
means it can be reprogrammed using Flash repro-
gramming procedures. However, if any of the CTMhardware components are damaged or faulty, the
entire CTM unit must be replaced. The power lock
system components and the hard wired inputs or out-
puts of the CTM can be diagnosed using conventional
diagnostic tools and methods; however, for diagnosis
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 infor-
mation.
DESCRIPTION - REMOTE KEYLESS ENTRY
SYSTEM
A Remote Keyless Entry (RKE) system is an avail-
able option on this model. The Remote Keyless Entry
(RKE) system is a Radio Frequency (RF) system that
allows the remote operation of the power lock system
and, if the vehicle is so equipped, the Vehicle Theft
Security System (VTSS). (Refer to 8 - ELECTRICAL/
VEHICLE THEFT SECURITY - DESCRIPTION).
The RKE system 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, an RF receiver, and the software that allow it
to provide the many electronic functions and features
of the RKE system.
²Keyless Entry Transmitter- The keyless
entry transmitter is a small, battery-powered, RF
transmitter that is contained within a molded plastic
case that is designed to also serve as a convenient
key fob.
Some additional features of the RKE system
include:
²Horn Chirp- This feature provides a short,
sharp chirp of the vehicle horn to give an audible
confirmation that a valid Lock signal has been
received from the RKE transmitter. This feature can
be enabled or disabled and, if enabled, one of two
optional horn chirp durations (twenty or forty milli-
seconds) can also be selected.
²Illuminated Entry- This feature turns on the
courtesy lamps in the vehicle for a timed interval
(about thirty seconds) each time a valid Unlock sig-
nal has been received from the RKE transmitter.
²Panic Mode- This feature allows the vehicle
operator to cause the vehicle horn to pulse, the head-
lights to flash, and the courtesy lamps to illuminate
for about three minutes by depressing a Panic button
on the RKE transmitter. Pressing the Panic button a
second time will cancel the Panic mode. A vehicle
speed of about 24 kilometers-per-hour (15 miles-per-
hour) will also cancel the panic mode.
8N - 2 POWER LOCKSBR/BE
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

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.

The automatic day/night mirror uses a thin layer
of electrochromic material between two pieces of con-
ductive glass to make up the face of the mirror.
When the mirror switch is in the On position, two
photocell sensors are used by the mirror circuitry to
monitor external light levels and adjust the reflec-
tance of the mirror.
