AUDIO/VIDEO
DESCRIPTION
An audio system is standard on this model. A rear
seat video system is an available option. Several com-
binations of radio receivers are offered on this model.
The audio/video system uses an ignition switched
source of battery current so that the system will only
operate when the ignition switch is in the RUN or
ACCESSORY/ACCESSORY DELAY positions.
The audio system includes the following compo-
nents:²Amplifier
²Antenna
²CD changer (if equipped)
²DVD player (if equipped)
²Radio noise suppression components
²Radio receiver
²Speakers
²Video screen (if equipped)
Certain functions and features of the audio/video
system rely upon resources shared with other elec-
tronic modules in the vehicle over the Programmable
Communication Interface (PCI) bus network. The
data bus network allows the sharing of sensor infor-
RSAUDIO/VIDEO8A-1

mation. For diagnosis of these electronic modules or
of the data bus network, the use of a DRB IIItscan
tool and the proper Diagnostic Procedures informa-
tion is recommended.
DIAGNOSIS AND TESTING
AUDIO/VIDEO
Any diagnosis of the Audio system should
begin with the use of the DRB IIItdiagnostic
tool. For information on the use of the DRBIIIt, refer to the appropriate Diagnostic Service
information.
Refer to the appropriate wiring information.
WARNING: ON VEHICLES EQUIPPED WITH AIR-
BAGS, REFER TO ELECTRICAL, RESTRAINTS

ANTENNA BODY AND CABLE
DESCRIPTION
Domestic vehicles 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.
OPERATION
To minimize 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.

DIAGNOSIS AND TESTING
ANTENNA BODY AND CABLE
WARNING: ON VEHICLES EQUIPPED WITH AIR-
BAGS, REFER TO ELECTRICAL, RESTRAINTS
BEFORE ATTEMPTING 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.
The ohmmeter test lead connections for each test
are shown in (Fig. 2).
TEST 1
Test 1 determines of the antenna mast is insulated
from the base. Proceed as follows:
(1) Unplug the antenna coaxial cable from the
radio chassis and isolate. Remove the antenna mast.
(2) Connect an ohmmeter test lead to the inside
center of the antenna base. Connect the other test
lead to a metallic portion on the outside of the
antenna base. Check for continuity.
(3) There should be no continuity. If continuity is
found, replace the faulty or damaged antenna base
and cable assembly.
TEST 2
Test 2 checks the antenna for an open circuit as
follows:
(1) Unplug the antenna coaxial cable connector
from the radio chassis. Remove the antenna mast.(2) Connect an ohmmeter test lead to the inside
center of the antenna base. 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 ground between
the antenna base and the vehicle body as follows:
(1) Connect one ohmmeter test lead to the fender
on an exposed metal area. Connect the other test
lead to the outer crimp on the antenna coaxial cable
connector.
(2) The resistance should be less than (1) ohm.
(3) If the resistance is more than (1) ohm, clean
and/or tighten the antenna base to the fender mount-
ing hardware.
REMOVAL
(1) Disconnect and isolate the battery negative
cable.
(2) Remove glove box from instrument panel,
(Refer to 23 - BODY/INSTRUMENT PANEL/GLOVE
BOX - REMOVAL).
(3) Disconnect antenna cable connector from exten-
sion cable (Fig. 3).
(4) Remove right kick trim panel.
(5) Disengage rubber grommet insulator from door
hinge pillar.
(6) Pull antenna cable through hinge pillar into
opening between door hinges.
(7) Hoist and support vehicle on safety stands.
(8) Remove front wheel.
(9) Remove front wheelhouse splash shield. (Refer
to 23 - BODY/EXTERIOR/LF WHEELHOUSE
SPLASH SHIELD - REMOVAL).
(10) Remove antenna mast from antenna base
(Fig. 4).
(11) Using cap nut tool, remove cap nut holding
antenna base to front fender (Fig. 5).
(12) Remove antenna base from under front
fender.
INSTALLATION
(1) Install antenna base to underside of front
fender.
(2) Install cap nut holding antenna base to front
fender.
(3) Install antenna mast to antenna baseEnsure
that the antenna mast is fully seated on
antenna base, and that there is no gap between
the mast and base..
