GENERAL INFORMATION
INTRODUCTION
Operating instructions for the factory installed
audio systems can be found in the Owner's Manual
provided with the vehicle.
The vehicles are equipped with an Interior (Igni-
tion Off Draw) fuse in the Power Distribution Center
located in the engine compartment. After the Interior
(IOD) fuse or battery has been disconnected the clock
will require resetting. The radio station presets have
a nonvolatile memory and will retain the preset sta-
tions after a battery disconnect.
The available radio options are:
²AM/FM Stereo Cassette w/Clock
²AM/FM/CD
²AM/FM Cassette w/CD Changer Controls and
Display
²CD/4 Disc Changer - In-Dash (used w/Radio CD
Changer Controls)
DESCRIPTION AND OPERATION
INTERFERENCE ELIMINATION
The radio utilizes a ground wire plugged on to a
blade terminal and is bolted to the radio chassis.
Both connector and terminal should be securely
attached. The engine has two separate ground straps
to suppress ignition noise which may interfere with
radio reception.
²Left engine mount clip on strap
²Engine to shock tower reinforcement
Inductive type spark plug cables in the high ten-
sion circuit of the ignition system complete the inter-
ference suppression. Faulty or deteriorated spark
plug wires should be replaced.
DIAGNOSIS AND TESTING
AUDIO DIAGNOSTIC TEST PROCEDURES
CAUTION: The CD player will only operate between
approximate temperatures of -23ÉC and +65ÉC (-10ÉF
and +145ÉF).
Whenever a radio malfunction occurs;
(1) First check FUSES:
(a) Power Distribution Center (PDC), Interior
lamp fuse, M1 - Radio Memory Feed
(b) Fuse Block:
(I) Fuse 12, Illumination in the fuse block
(II) Fuse 16, Ignition feed in the fuse block
NOTE: The vehicles are shipped with the INTERIOR
LAMP fuse disconnected.
(2) Verify, the radio wire harness are properly con-
nected before starting normal diagnosis and repair
procedures. Refer to Audio Diagnostic Charts and/or
Group 8W, Wiring Diagrams, Radio Section.
TESTING
The antenna has a short cable which connects into
the instrument panel harness. The connection is
made on the right side of the instrument panel.
Antenna performance may be tested by substitut-
ing a known good antenna. It is also possible to
check short or open circuits with an ohmmeter or
continuity light once the antenna cable is discon-
nected from the radio as follows:
(1) Continuity should be present between the
antenna mast and radio end pin of antenna cable
plug (Fig. 1).
(2) No continuity should be observed or a very
high resistance of several megohms between the
ground shell of the connector and radio end pin.

(3) Continuity should be observed between the
ground shell of the connector and the mounting hard-
ware on the vehicle antenna. The wheel well splash
shield must be removed for access to the antenna
that is mounted on load beam.
BENCH TEST FOR ANTENNA MALFUNCTION
It is also possible to check short or open circuits
with an ohmmeter or continuity light once the
antenna has been removed from the vehicle.
(1) Continuity should be present between the tip of
the mast and radio lead in (Fig. 2).
(2) No continuity should be observed or a very
high resistance of several megohms between the
ground shell of the connector and radio end pin.
(3) Continuity should be observed between the
ground shell of the connector and the mounting
bracket.Wiggle cable over its entire length to
reveal intermittent short or open circuits dur-
ing step 1, 2 and 3.
REMOVAL AND INSTALLATION
CD CHANGER
REMOVAL
(1) Disconnect and isolate the battery negative
cable (Fig. 3).
(2) Using a trim stick (special tool #C-4755), gently
pry out on CD changer bezel and remove.
