GENERAL INFORMATION
INTRODUCTION
Operating instructions for the factory installed
audio systems can be found in the Owner's Manual
provided with the vehicle.
NS vehicles are equipped with an Ignition Off
Draw (IOD) fuse in the power distribution center
located in the engine compartment. After the IOD
fuse or battery has been disconnected, the radio sta-
tion sets and clock will require resetting.
DESCRIPTION AND OPERATION
ANTENNA
All models use a fixed-length stainless steel rod-
type antenna mast, installed at the right front fender
of the vehicle. The antenna mast is connected to the
center wire of the coaxial antenna cable, and is not
grounded to any part of the vehicle.
To eliminate static, the antenna base must have a
good ground. The coaxial antenna cable shield (the
outer wire mesh of the cable) is grounded to the
antenna base and the radio chassis.
The antenna coaxial cable has an additional dis-
connect, located near the right end of the instrument
panel. This additional disconnect allows the instru-
ment panel assembly to be removed and installed
without removing the radio.
The factory-installed Electronically Tuned Radios
(ETRs) automatically compensate for radio antenna
trim. Therefore, no antenna trimmer adjustment isrequired or possible when replacing the receiver or
the antenna.
INTERFERENCE ELIMINATION
Some components used on the vehicles are
equipped with a capacitor to suppress radio fre-
quency interference/static.
Capacitors are mounted in various locations inter-
nal to the generator, instrument cluster and wind-
shield wiper motor.
To eliminate radio interference, ground straps are
used in different areas of the vehicle. These ground
circuits should be securely tightened to assure good
metal to metal contact. The ground straps conduct
very small high frequency electrical signals to ground
and require clean surface contact area. The radio
ground is supplied from the instrument panel har-
ness and is attached to the rear of the radio. Some
engines have other ground straps to eliminate fur-
ther radio interference:
²Radio chassis to instrument panel structure
²Engine to dash panel
²Engine to chassis
²A/C h valve to dash panel
Radio resistance type spark plug cables in the high
tension circuit of the ignition system complete the
interference suppression. Faulty or deteriorated
spark plug wires should be replaced.
RADIOS
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/

TEST 2
Test 2 checks the antenna for an open circuit as
follows:
(1) Unplug the antenna coaxial cable connector
from the radio chassis.
(2) Connect one ohmmeter test lead to the tip of
the antenna mast. Connect the other test lead to the
center pin of the antenna coaxial cable connector.
(3) Continuity should exist (the ohmmeter should
only register a fraction of an ohm). High or infinite
resistance indicates damage to the base and cable
assembly. Replace the faulty base and cable, if
required.
TEST 3
Test 3 checks the condition of the vehicle body
ground connection. This test should be performed
with the battery positive cable removed from the bat-
tery. Disconnect both battery cables, the negative
cable first. Reconnect the battery negative cable and
perform the test as follows:
(1) Connect one ohmmeter test lead to the vehicle
fender. Connect the other test lead to the battery
negative post.
(2) The resistance should be less than (1) ohm.
(3) If the resistance is more than (1) ohm, check
the braided ground strap connected to the engine and
the vehicle body for being loose, corroded, or dam-
aged. Repair the ground strap connection, if required.
TEST 4
Test 4 checks the condition of the ground between
the antenna base and the vehicle body as follows:(1) Connect one ohmmeter test lead to the vehicle
fender. Connect the other test lead to the outer crimp
on the antenna coaxial cable connector.
(2) The resistance should be less then (1) ohm.
(3) If the resistance is more then (1) ohm, clean
and/or tighten the antenna base to fender mounting
hardware.

WARNING: ON VEHICLES EQUIPPED WITH AIR-
BAGS, REFER TO GROUP 8M - PASSIVE
RESTRAINT SYSTEMS BEFORE ATTEMPTING ANY
STEERING WHEEL, STEERING COLUMN, OR
INSTRUMENT PANEL COMPONENT DIAGNOSIS OR
SERVICE. FAILURE TO TAKE THE PROPER PRE-
CAUTIONS COULD RESULT IN ACCIDENTAL AIR-
BAG DEPLOYMENT AND POSSIBLE PERSONAL
INJURY.
RADIO
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
Group 8W - Wiring Diagrams.

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.
