Refer to Electrical, Restraints for more information
on the clockspring. Refer to Electrical, Body Control/
Central Control Module for more information on the
Central Timer Module. Refer to the appropriate wir-
ing information. The wiring information includes wir-
ing 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. Following are general descriptions of
the remaining major components in the standard and
optional factory-installed audio systems.
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.

AUDIO (Continued)

commercial radio stations in both the Amplitude
Modulating (AM) and Frequency Modulating (FM)
frequency ranges. These electromagnetic radio fre-
quency signals induce small electrical modulations
into the antenna as they move past the mast. The
antenna body transfers the weak electromagnetic
radio waves induced into the rigid antenna mast into
the center conductor of the flexible primary antenna
coaxial cable. The braided outer shield of the
antenna coaxial cable is grounded through both the
antenna body and the radio chassis, effectively
shielding the radio waves as they are conducted to
the radio. The radio then tunes and amplifies the
weak radio signals into stronger electrical signals in
order to operate the audio system speakers.
The antenna body includes an integral flange that
mates with and grounds the antenna body to the
underside of the fender panel sheet metal. Above the
fender panel, the antenna body has a short nipple
that is externally threaded to accept the antenna cap
nut. Inside the nipple is a plastic insulator tube, and
inside this insulator is an internally threaded metal
receptacle that accepts the adapter stud on the bot-
tom of the antenna mast. The antenna adapter
serves as an above fender interface to mount and
secure the antenna body to the vehicle. The antenna
adapter is a black molded plastic component that
provides a functional transition between the top of
the fender and the antenna cap nut, while concealing
the edges of the antenna mounting hole and protect-
ing the painted finish of the fender from marring as
the antenna cap nut is tightened. The adapter is
installed over and shrouds the threaded nipple of the
antenna body, which is installed from under and pro-
trudes through the top of the mounting hole in the
fender. The antenna cap nut is installed on top of the
antenna adapter and tightened onto the external
threads of the antenna body nipple to effectively
secure and ground the antenna body to the fender.
Three notches on the outer circumference of the cap
nut are engaged by matching projections of an
antenna nut wrench (Special Tool C-4816) to facili-
tate the removal and installation of this special fas-
tener. Proper tightening of the antenna cap nut is
critical to ensuring proper grounding of the antenna
body to the fender sheet metal, which is necessary
for clear radio signal reception.
A short length of coaxial cable serves as the pri-
mary antenna cable. The center conductor of the
cable is connected to the antenna mast receptacle.
The outer wire mesh of the cable is connected to and
grounded through the antenna body. One end of the
primary antenna cable is securely crimped to the
lower end of the antenna body, while the opposite
end features a simple push/pull-type male coaxial
cable connector that serves as the in-line connector tothe instrument panel (secondary) antenna coaxial
cable. The primary coaxial cable includes a grommet
that seals the cable to an entry hole in the right cowl
side outer panel where the cable passes into the pas-
senger compartment of the vehicle. The secondary
antenna cable has a push/pull-type male coaxial
cable connector on the radio end, and a push/pull-
type female coaxial cable connector on the opposite
end, which serves as the in-line connector to the pri-
mary antenna cable. In the passenger compartment
the primary cable is routed to the lower right side of
the instrument panel, where it is connected to the
secondary instrument panel antenna cable. The
instrument panel antenna cable is routed near the
instrument panel wire harness through the instru-
ment panel to the radio and is secured to the instru-
ment panel structural support with small metal
push-on retainers. This two-piece antenna cable
arrangement allows the instrument panel or the
antenna body and cable to be removed or installed
without disturbing the radio.

RADIO
DESCRIPTION
Available factory-installed radio receivers for this
model include an AM/FM/cassette (RAS sales code),
an AM/FM/cassette/5-band graphic equalizer with CD
changer control feature (RBN sales code), an AM/FM/
CD/3-band graphic equalizer (RBR sales code), or an
AM/FM/CD/cassette/3-band graphic equalizer (RAZ
sales code). The factory-installed RAZ sales code
radio receivers can also communicate on the Chrysler
Collision Detection (CCD) data bus network through
a separate two-way wire harness connector. All facto-
ry-installed receivers are stereo Electronically Tuned
Radios (ETR) and include an electronic digital clock
function.These radio receivers can only be serviced by an
authorized radio repair station. See the latest War-
ranty Policies and Procedures manual for a current
listing of authorized radio repair stations.
All vehicles are equipped with an Ignition-Off
Draw (IOD) fuse that is removed when the vehicle is
shipped from the factory. This fuse feeds various
accessories that require battery current when the
ignition switch is in the Off position, including the
clock. The IOD fuse is removed to prevent battery
discharge during vehicle storage.
When removing or installing the IOD fuse, it is
important that the ignition switch be in the Off posi-
tion. Failure to place the ignition switch in the Off
position can cause the radio display to become scram-
bled when the IOD fuse is removed and replaced.
Removing and replacing the IOD fuse again, with the
ignition switch in the Off position, will correct the
scrambled display condition.
The IOD fuse should be checked if the radio or
clock displays are inoperative. The IOD fuse is
located in the junction block. Refer to the fuse layout
label on the back of the instrument panel fuse access
panel for IOD fuse identification and location.
OPERATION
The radio receiver operates on fused battery cur-
rent that is available only when the ignition switch is
in the On or Accessory positions. The electronic digi-
tal clock function of the radio operates on fused bat-
tery current supplied through the IOD fuse,
regardless of the ignition switch position.
For more information on the features, setting pro-
cedures, and control functions for each of the avail-
able factory-installed radio receivers, see the owner's
manual in the vehicle glove box. For complete circuit
diagrams, refer to the appropriate wiring informa-
tion. The wiring information includes wiring dia-
grams, proper wire and connector repair procedures,
details of wire harness routing and retention, connec-
tor pin-out information and location views for the
various wire harness connectors, splices and grounds.
