OPERATION
See the owner's manual in the vehicle glove box for
more information on the features, use and operation
of each of the available audio systems.
CENTRAL TIMER MODULE
The high-line or premium Central Timer Module
(CTM) can also control some features of the audio
system when the vehicle is equipped with the
optional RAZ radio receiver and remote radio
switches. A high-line CTM is used on high-line ver-
sions of this vehicle. A premium CTM is used on
vehicles equipped with the optional heated seats. The
CTM combines the functions of a chime/buzzer mod-
ule, an intermittent wipe module, an illuminated
entry module, a remote keyless entry module, and a
vehicle theft security system module in a single unit.
The high-line or premium CTM also controls and
integrates many of the additional electronic functions
and features included on models with this option.The RAZ radio receiver with a remote radio switch
option is one of the features that the CTM controls.
The CTM is programmed to send switch status mes-
sages over the Chrysler Collision Detection (CCD)
data bus to control the volume, seek, and pre-set sta-
tion advance functions of the RAZ radio receiver. The
CTM monitors the status of the remote radio
switches located on the steering wheel through a
hard wired circuit. The CTM then sends the proper
switch status messages to the radio receiver. The
electronic circuitry within the radio receiver responds
to the switch status messages it receives by adjusting
the radio settings as requested.
Refer to Electrical, Body Control/Central Timer
Module for more information on the high-line CTM.
Refer to Remote Radio Switch in Description and
Operation for more information on this component.
In addition, radio receivers connected to the CCD
data bus have several audio system functions that
can be diagnosed using a DRBIIItscan tool. Refer to
the proper Diagnostic Procedures manual for more
information on DRBIIIttesting of the audio systems.

premium speaker package and all of the speakers
are inoperative, refer to Filter, Choke, and Speaker
Relay in the Diagnosis and Testing section of this
group.
(2) Turn the radio receiver off. Turn the ignition
switch to the Off position. Disconnect and isolate the
battery negative cable. Remove the radio receiver
from the instrument panel. Check both the feed (+)circuit and return (±) circuit cavities for the inopera-
tive speaker location(s) in the radio receiver wire
harness connectors for continuity to ground. In each
case, there should be no continuity. If OK, go to Step
3. If not OK, repair the shorted speaker feed (+)
and/or return (±) circuit(s) to the speaker as required.
(3) If the inoperative speaker is an Infinity-ampli-
fied speaker, go to Step 5. If the vehicle is equipped
with the standard speaker system, check the resis-
tance between the speaker feed (+) circuit and return
(±) circuit cavities of the radio receiver wire harness
connectors for the inoperative speaker location(s).
The meter should read between 2.5 and 4 ohms
(speaker resistance). If OK, go to Step 4. If not OK,
go to Step 5.
(4) Install a known good radio receiver. Connect
the battery negative cable. Turn the ignition switch
to the On position. Turn on the radio receiver and
test the speaker operation. If OK, replace the faulty
radio receiver. If not OK, turn the radio receiver off,

inoperative standard speaker system speaker or at
the Infinity-amplified front door-mounted speaker.
Check for continuity between the speaker feed (+) cir-
cuit cavities of the radio receiver wire harness con-
nector and the speaker wire harness connector for
the inoperative speaker location. Repeat the check
between the speaker return (±) circuit cavities of the
radio receiver wire harness connector and the
speaker wire harness connector for the inoperative
speaker location. In each case, there should be conti-
nuity. If OK with an Infinity-amplified front door-
mounted speaker, go to Step 6. If OK with the
standard speaker system, replace the faulty speaker.
If not OK, repair the open speaker feed (+) and/or
return (±) circuit(s) as required.
(6) Check for continuity between the ground cir-
cuit cavity in the body half of the wire harness con-
nector for the Infinity-amplified front door-mounted
speaker on the same side of the vehicle as the inop-
erative speaker and a good ground. There should be
continuity. If OK, go to Step 7. If not OK, repair the
open ground circuit to ground as required.
(7) Install the radio receiver. Connect the battery
negative cable. Turn the ignition switch to the On
position. Turn the radio receiver on. Check for bat-
tery voltage at the radio choke output circuit cavity
of the wire harness connector for the Infinity-ampli-
fied front door-mounted speaker on the same side of

external connector receptacles that connect it to the
vehicle electrical system through one (base) or two
(high-line/premium) take outs with connectors from
the instrument panel wire harness.
The base version of the CTM is used on base mod-
els of this vehicle. It is also sometimes referred to as
the Integrated Electronic Module (IEM). The base
version of the CTM combines the functions of a
chime module and an intermittent wipe module in a
single unit. The high-line version of the CTM is used
on high-line vehicles. The high-line CTM provides all
of the functions of the base version of the CTM, but
also is used to control and integrate many additional
electronic functions and features included on high-
line models. The premium version of the CTM is the
same as the high-line version, but is used only on
models equipped with the heated seat option.
The high-line and premium versions of the CTM
utilize integrated circuitry and information carried
on the Chrysler Collision Detection (CCD) data bus
network along with many hard wired inputs to mon-
itor many sensor and switch inputs throughout the
vehicle. In response to those inputs, the internal cir-
cuitry and programming of the CTM allow it to con-
trol and integrate many electronic functions and
features of the vehicle through both hard wired out-
puts and the transmission of electronic message out-
puts to other electronic modules in the vehicle over
the CCD data bus.
The features that the CTM supports or controls
include the following:
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.
²Chimes- All versions of the CTM provide chime
service through an integral chime tone generator.
²Courtesy Lamps- The high-line/premium CTM
provides courtesy lamp control with timed load shed-
ding.
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.
²Heated Seats- The premium CTM controls the
optional heated seat system by controlling the opera-
tion of the heated seat relay.
²Illuminated Entry- The high-line/premium
CTM provides a timed illuminated entry feature.²Intermittent Wipe Control- All versions of

vides support for the optional RKE system panic
mode features.
²Power Lock Control- The high-line/premium
CTM provides the optional power lock system fea-
tures, including support for the automatic door lock
and door lock inhibit modes.
²Programmable Features- The high-line/pre-
mium CTM provides support for certain programma-
ble features.
²Remote Keyless Entry- The high-line/pre-
mium CTM provides the optional Remote Keyless
Entry (RKE) system features, including support for
the RKE Lock (with optional horn chirp), Unlock,
Panic, and illuminated entry modes, as well as the
ability to be programmed to recognize up to four
RKE transmitters. The RKE horn chirp is a program-
mable feature.
²Remote Radio Switch Interface- The high-
line/premium CTM monitors and transmits the sta-
tus of the optional remote radio switches.
²Speed Sensitive Intermittent Wipe Control-
The high-line/premium CTM provides the speed sen-
sitive intermittent wipe feature.
²Vehicle Theft Alarm- The high-line/premium
CTM provides control of the optional Vehicle Theft
Alarm features, including support for the central
locking/unlocking mode.
Hard wired circuitry connects the CTM to the elec-
trical system of the vehicle. 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
CTM through the use of a combination of soldered
splices, splice block connectors, and many different
types of wire harness terminal connectors and insu-
lators. 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.
All versions of the CTM for this model are serviced
only as a complete unit. Many of the electronic fea-
tures in the vehicle controlled or supported by the
high-line or premium versions of the CTM are pro-
grammable using the DRBIIItscan tool. In addition,
the high-line/premium CTM software is Flash com-
patible, 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

MIRROR SWITCH
DESCRIPTION
The heated mirror switch, the heated mirror sys-
tem indicator lamp, the heated mirror system solid
state electronic control logic and timer circuitry and
the heated mirror relay are all integral to the a/c
heater control, which is located between the instru-
ment cluster and the radio near the center of the
instrument cluster bezel on the instrument panel.
The heated mirror switch and the heated mirror sys-
tem indicator lamp are visible in the lower left corner
of the a/c heater control face plate (Fig. 2).
The heated mirror switch, the heated mirror sys-
tem indicator lamp, the heated mirror system solid
state electronic control logic and timer circuitry and
the heated mirror relay cannot be repaired. If any of
these components is damaged or faulty, the entire a/c
heater control must be replaced. (Refer to 24 - HEAT-
ING & AIR CONDITIONING/CONTROLS/A/C
HEATER CONTROL - REMOVAL)
OPERATION
The momentary-type heated mirror switch provides
a hard-wired battery current signal to the heated
mirror system electronic control logic circuitry each
time it is depressed. In response to the heated mirror
switch input, the electronic control logic and timer
circuitry energizes or de-energizes the amber heated
mirror system indicator lamp next to the heated mir-
ror switch to indicate that the heated mirror systemis turned On or Off. The electronic control logic and
timer circuitry also energizes or de-energizes the
heated mirror relay, which controls the feed of elec-
trical current to the outside mirror heating grids.
The heated mirror system electronic control logic
and timer circuitry is programmed to turn the heated
mirror system Off automatically after about fifteen
minutes of operation. If the heated mirror system is
turned On a second time following an initial time-out
event during the same ignition switch cycle, the
heated mirror system electronic control logic and
timer circuit is programmed to turn the system Off
automatically after about five minutes. When the
electronic control logic and timer circuit detects that
a programmed time interval has elapsed, it will auto-
matically de-energize the heated mirror system indi-
cator lamp and the heated mirror relay. The heated
mirror system will also be turned Off if the heated
mirror switch is depressed while the system is
turned On, or if the ignition switch is turned to the
Off or Accessory positions.
DIAGNOSIS AND TESTING - HEATED MIRROR

HEATED SEAT SYSTEM
DESCRIPTION
Individually controlled electrically heated front
seats are available factory-installed optional equip-
ment on the Ram quad cab models that are also
equipped with the optional SLT Plus (leather) trimpackage. Vehicles with this option can be visually
identified by the two separate heated seat switches
mounted in a bezel located in the lower right corner
of the instrument cluster bezel, next to the radio
receiver (Fig. 1). The heated seat system allows the
front seat driver and passenger to select from two
different levels of supplemental electrical seat heat-
ing, or no seat heating to suit their individual com-
fort requirements. The heated seat system for this
vehicle includes the following major components:
²The heated seat switches, including two heated
seat Light-Emitting Diode (LED) indicator lamps and
an incandescent back lighting bulb for each switch.
²The heated seat module, also referred to as the
Seat Heat Interface Module (SHIM), which contains
the solid state electronic control and diagnostic logic
circuitry for the heated seat system. Refer to the
Electronic Control Modules section of the service
manual for heated seat module information.
²The heated seat elements and sensors, which
are integral to the individual front seat cushion and
front seat back trim covers.
²The heated seat relay, which controls the avail-
ability of battery current to the heated seat module
or SHIM.
Following are general descriptions of the major
components in the heated seat system. See the own-
er's manual in the vehicle glove box for more infor-
mation on the features, use and operation of the
heated seat system. Refer toPower Seatin the
index of this service manual for the location of com-
plete heated seat system wiring diagrams.

BR/BEHEATED SEAT SYSTEM 8G - 5

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:

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

INSTRUMENT PANEL SYSTEM
DESCRIPTION
The instrument panel is located at the front of the
passenger compartment. This instrument panel is
molded from a blend of various plastics that are
mechanically attached to the vehicle. Colors are
molded into the plastic components to minimize
appearance degradation from scratches or abrasions.
The panel components are internally ribbed and riv-
eted to steel reinforcements for additional structural
integrity and dimensional stability. The instrument
panel surface components are designed to deform
upon impact without breaking. This type of construc-
tion provides improved energy absorption which, in
conjunction with the dual airbags and seat belts,
helps to improve occupant protection.
The top of the instrument panel is secured to the
top of the dash panel near the base of the windshield
using screws. An end bracket integral to each end of
the instrument panel structure is secured to each
cowl side inner panel with a screw. A stamped metal
bracket supports the center of the instrument panel
by securing it to the top of the floor panel transmis-
sion tunnel below the instrument panel with screws.
