ANTENNA MODULE - EXPORT
DESCRIPTION
The antenna module is an electromagnetic circuit
component designed to capture and enhance RF
(Radio Frequency) signals in both the AM and FM
broadcast bands. The antenna module is mounted to
the right rear roof rail under the headliner. The mod-
ule is grounded through the mounting bracket and
fastener. The module has a two wire electrical con-
nector that connects to the integral radio antenna,
located on the right rear quarter glass. There is also
an electrical connector for battery voltage and a coax
cable connector.
OPERATION
The antenna module receives both AM and FM
radio signals supplied by the side window integral
radio antenna system and selectively amplifies them.
The amplified signal is then sent through the body
length coax cable to the radio input.

CD CHANGER
DESCRIPTION
The 4 Disc In-Dash CD Changer (if equipped) is
located in the instrument panel below the radio. The
remote changer does not use a cartridge or magazine
for the CD's. Up to 4 CD's can be directly loaded into
this unit.
OPERATION
Due to its compact design, the CD changer can
carry out only one operation at a time. For example,you can not load a new disc while playing another at
the same time. Each operation happens sequentially.
The radio unit provides control over all features of
the CD changer with the exception of the CD load
and eject functions, which are controlled by buttons
located on the front of the CD changer. All features
you would expect, such as Disc Up/Down, Track
Up/Down, Random and Scan are controlled by the
radio, which also displays all relevant CD changer
information on the radio display.
The CD changer contains a Load/Eject button and
an indicator LED for each of the four disc positions
as well as an illuminated disc opening. The individ-
ual LED indicates whether a CD is currently loaded
in that particular chamber of the CD changer. Press-
ing the individual Load/Eject button for a particular
chamber will eject a disc currently present in that
chamber. If the chamber is currently empty, actuat-
ing the Load/Eject button will position that chamber
to receive and load a new disc in that chamber.
REMOVAL
(1) Disconnect and isolate the battery negative
cable.
(2) Remove screws holding CD changer.
(3) Disconnect the wire connector from the back of
the CD changer.
(4) Remove the CD changer from the vehicle (Fig.

QUARTER GLASS INTEGRAL
ANTENNA - EXPORT
DESCRIPTION
The quarter glass integral antenna element is
bonded to the right rear quarter glass and is replaced
with the glass assembly only (Fig. 7).
OPERATION
The integral antenna receives RF (Radio Frequen-
cies) and sends them to the antenna module for
amplification.
DIAGNOSIS AND TESTING - QUARTER GLASS
INTEGRAL ANTENNA - EXPORT
The antenna grid pattern is divided into two sepa-
rate patterns. Each terminal connects to a separate
grid pattern, one for AM and the other for FM.
For circuit descriptions and diagrams, refer to the
appropriate 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. To detect breaks in the
integral antenna elements, the following procedure is
required:
(1) Disconnect the antenna module connector from
the antenna terminals on the glass.
(2) Using an ohmmeter, place a lead on one of the
terminals and check each end of the grid pattern con-
nected to this terminal for continuity. If continuity is
not present, move one lead through the grid in pro-
gression starting at the terminal with the other lead
on the terminal until continuity is lost. Repeat pro-
cedure for the other terminal. A break in the antenna
grid can be repaired using a Mopar Rear Window
Defogger Repair Kit (Part Number 4267922) or
equivalent. (Refer to 8 - ELECTRICAL/HEATED
GLASS/WINDSHIELD GRID - STANDARD PROCE-
DURE).

RADIO NOISE SUPPRESSION
COMPONENTS
DESCRIPTION
Radio noise suppression devices are factory-in-
stalled standard equipment on this vehicle. Radio
Frequency Interference (RFI) and ElectroMagnetic
Interference (EMI) can be produced by any on-board
or external source of electromagnetic energy. These
electromagnetic energy sources can radiate electro-
magnetic signals through the air, or conduct them
through the vehicle electrical system.
When the audio system converts RFI or EMI to an
audible acoustic wave form, it is referred to as radionoise. This undesirable radio noise is generally man-
ifested in the form of ªbuzzing,º ªhissing,º ªpopping,º
ªclicking,º ªcrackling,º and/or ªwhirringº sounds. In
most cases, RFI and EMI radio noise can be sup-
pressed using a combination of vehicle and compo-
nent grounding, filtering and shielding techniques.
This vehicle is equipped with factory-installed radio
noise suppression devices that were designed to min-
imize exposure to typical sources of RFI and EMI;
thereby, minimizing radio noise complaints.
Factory-installed radio noise suppression is accom-
plished primarily through circuitry or devices that
are integral to the factory-installed radios, audio
power amplifiers and other on-board electrical com-
ponents such as generators, wiper motors, blower
motors, and fuel pumps that have been found to be
potential sources of RFI or EMI.
OPERATION
There are two common strategies that can be used
to suppress Radio Frequency Interference (RFI) and
ElectroMagnetic Interference (EMI) radio noise. The
first suppression strategy involves preventing the
production of RFI and EMI electromagnetic signals
at their sources. The second suppression strategy
involves preventing the reception of RFI and EMI
electromagnetic signals by the audio system compo-
nents.
The use of braided ground straps in key locations
is part of the RFI and EMI prevention strategy.
These ground straps ensure adequate ground paths,
particularly for high current components such as
many of those found in the starting, charging, igni-
tion, engine control and transmission control sys-
tems. An insufficient ground path for any of these
high current components may result in radio noise
caused by induced voltages created as the high cur-
rent seeks alternative ground paths through compo-
nents or circuits intended for use by, or in close
proximity to the audio system components or circuits.
Preventing the reception of RFI and EMI is accom-
plished by ensuring that the audio system compo-
nents are correctly installed in the vehicle. Loose,
corroded or improperly soldered wire harness connec-
tions, improperly routed wiring and inadequate audio
system component grounding can all contribute to
the reception of RFI and EMI. A properly grounded
antenna body and radio chassis, as well as a shielded
antenna coaxial cable with clean and tight connec-
tions will each help reduce the potential for reception
of RFI and EMI.

REMOTE SWITCHES
DESCRIPTION
A remote radio control switch option is available on
some models. Two rocker-type switches are mounted
on the back (instrument panel side) of the steering
wheel spokes (Fig. 10). The switch on the left spoke
is the seek switch and has seek up, seek down, and
preset station advance functions. The switch on the
right spoke is the volume control switch and has vol-
ume up, and volume down functions. The switch on
the right spoke also includes a ªmodeº control that
allows the driver to sequentially select AM radio, FM
radio, cassette player, CD player or CD changer (if
equipped).
OPERATION
These switches are resistor multiplexed units that
are hard-wired to the Body Control Module (BCM)
through the clockspring. The BCM sends the proper
messages on the Programmable Communications
Interface (PCI) data bus network to the radio
receiver. For diagnosis of the BCM or the PCI data
bus, the use of a DRB IIItscan tool and the proper
Diagnostic Procedures manual are recommended. For
more information on the operation of the remote
radio switch controls, refer to the owner's manual in
the vehicle glove box.
