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.

RADIO
DIAGNOSIS AND TESTING
If the vehicle is equipped with remote radio
switches located on the backs of the steering wheel
spokes, and the problem being diagnosed is related to
one of the symptoms listed below, be certain to check
the remote radio switches and circuits as described
in this group, prior to attempting radio diagnosis or
repair.
²Stations changing with no remote radio switch
input
²Radio memory presets not working properly
²Volume changes with no remote radio switch
input
²Remote radio switch buttons taking on other
functions
²CD player skipping tracks
²Remote radio switch inoperative.
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.
WARNING:
ON VEHICLES EQUIPPED WITH AIRBAGS, REFER
TO ELECTRICAL, RESTRAINTS BEFORE ATTEMPT-
ING ANY STEERING WHEEL, STEERING COLUMN,
OR INSTRUMENT PANEL COMPONENT DIAGNOSIS
OR SERVICE. FAILURE TO TAKE THE PROPER
PRECAUTIONS COULD RESULT IN ACCIDENTAL
AIRBAG DEPLOYMENT AND POSSIBLE PERSONAL
INJURY.
CAUTION:
The speaker output of the radio is a ªfloating
groundº system. Do not allow any speaker lead to
short to ground, as damage to the radio may result.
(1) Check the fuse(s) in the junction block and the
Intelligent Power Module. If OK, go to Step 2. If not
OK, repair the shorted circuit or component as
required and replace the faulty fuse(s).
(2) Check for battery voltage at the fuse in the
Intelligent Power Module. If OK, go to Step 3. If not

RADIO NOISE SUPPRESSION
COMPONENTS
DESCRIPTION
Numerous ground straps are placed throughout the
vehicle for interference elimination (Fig. 11), (Fig.
12), (Fig. 13), (Fig. 14).
OPERATION
If receiving ignition/engine interference noise on
the radio stations, check and clean all engine and
body ground connections. Ensure all ground connec-
tions are without corrosion. Tighten properly after
cleaning.

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. 15). 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 Chrysler Collision Detection (CCD)
data bus network to the radio receiver. For diagnosis
of the BCM or the CCD data bus, the use of a DRB
scan tool and the proper Diagnostic Procedures man-
ual 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.

itor to discharge before further service.
(2) Remove the remote radio switch(es) from the
steering wheel. (Refer to 8 - ELECTRICAL/AUDIO/
REMOTE SWITCHES - REMOVAL).
(3) Use an ohmmeter to check the switch resis-
tance as shown in the Remote Radio Switch Test
table (Fig. 16).

(4) If the switch resistance checks OK, go to Step
5. If not OK, replace the faulty switch.
(5) Check for continuity between the ground cir-
cuit cavity of the switch wire harness connector and
a good ground. There should be continuity. If OK, go
to Step 6. If not OK, repair the open circuit as
required.
(6) Unplug the 24-way white wire harness connec-
tor from the Body Control Module (BCM). Check for
continuity between the radio control circuit cavity of
the remote radio switch wire harness connector and a
good ground. There should be no continuity. If OK, go
to Step 7. If not OK, repair the short circuit as
required.
(7) Check for continuity between the radio control
circuit cavities of the remote radio switch wire har-
ness connector and the BCM wire harness connector.
There should be continuity. If OK, refer to the proper
Diagnostic Procedures manual to test the BCM and
the CCD data bus. If not OK, repair the open circuit
as required.
