DESCRIPTION
For operation of the factory installed standard and
optional radios and the optional compact disc player,
refer to the Sound Systems Operating Instructions
Manual supplied with the vehicle. All vehicles are equipped with an Ignition-Off
Draw Connector which, is used when the vehicles are
originally shipped from the factory. This connector
which, is located near the battery, helps to prevent
battery discharge during storage. For specific connec-
tor type and location, refer to Group 8W, Wiring Di-
agrams. This connector is included in the radio memory cir-
cuitry and should be checked if the memory of time
or radio station programming is inoperative.
INTERFERENCE ELIMINATION
Some components are used on vehicles equipped
with a radio capacitor, to suppress radio frequency
interference/static. Capacitors are mounted in various locations, on the
generator either internal or external, internal to the
instrument cluster, and internal to the windshield
wiper motor. Ground straps are mounted from radio chassis to
instrument panel support structure, engine to cowl,
across engine mount on right hand side. On vehicles
with air conditioning there is a strap from evapora-
tor valve to cowl. These ground straps should be se-
curely tightened to assure good metal to metal
contact. Ground straps conduct very small high fre-
quency electrical signals to ground and require clean
large surface area contact. Radio resistance type spark plug cables in the high
tension circuit of the ignition system complete the in-
terference suppression (Fig. 1).
If radio noises are evident, be sure the capacitor
lead wires are making good contact on their respec-
tive terminals and are securely mounted. Faulty or
deteriorated spark plug wires should be replaced.
AUDIO DIAGNOSTIC TEST PROCEDURES
Whenever a audio malfunction occurs, first verify
that the radio wire harness is properly connected to
all connectors before starting normal diagnosis and
repair procedures. Refer to Audio Diagnostic Charts
and/or Radio Connector Circuit Chart (Fig. 2).

COMPACT DISC PLAYER
WARNING: USE OF THE CONTROLS, ADJUST-
MENTS, OR SERVICE PROCEDURES NOT SPECI-
FIED HERE OR IN THE OWNER MANUAL MAY
RESULT IN HAZARDOUS RADIATION EXPOSURE.
REPAIR PROCEDURES SHOULD ONLY BE PER-
FORMED BY A TRAINED TECHNICIAN.
DIAGNOSIS TEST
Power to the compact disc player is supplied by the
radio through the CD interface cable. The compact
disc player will only work with the radio system
turned ON. When a compact disc is inserted with the
label side facing up, the disc is automatically loaded
and will begin to play. The CD player may eject the disc with a display of
E under the following conditions:
² The surface of the disc is dirty or wet
² The disc was inserted with the label side facing
down
² The disc is defective
² The CD player may skip or mute while playing a
disc under severe vibration conditions example pot
holes, railroad tracks, etc.
² If the CD player becomes too hot at temperatures
above 60ÉC (140 ÉF) the CD player will shut down
with a display of HOT until it cools down. Refer to
the Audio Diagnostic Charts.

GENERAL INFORMATION
WARNING: ON VEHICLES EQUIPPED WITH AIR-

AIRBAG REMOVAL PROCEDURES.
TURN SIGNALSÐAC, AY, AA AND AP BODIES
The turn signals are part of the multi-function switch.
Which contains electrical circuitry for turn signal, cor-
nering lamps, hazard warning, headlamp beam select,
headlamp optical horn, windshield wiper, pulse wipe
and windshield washer switching. The integrated switch
assembly is mounted to the left hand side of the steer-
ing column. When the driver wishes to signal his inten-
tions to change direction of travel, he moves the lever
upward to cause the right signals to flash and down-
ward to cause the left signals to flash. After completion
of a turn the system is deactivated automatically. As
the steering wheel returns to the straight ahead posi-
tion, a canceling cam of two lobes molded to the clock-
spring mechanism comes in contact with the cancel
actuator on the turn signal multi-function switch as-
sembly. Either cam lobe, pushing on the cancel actua-
tor, returns the switch to the off position. If only momentary signaling such as indication of a
lane change is desired, the switch is actuated to a left
or right intermediate detent position. In this position
the signal lamps flash as described above, but the
switch returns to the OFF position as soon as the lever
is released.
When the system is activated, 1 of 2 indicator
lamps mounted in the instrument cluster flashes in
unison with the turn signal lamps, indicating to the
driver that the system is operating.
AG AND AJ BODIES
The turn signals are actuated with lever on the left
side of the instrument panel switch pod. When the
driver wishes to signal his intentions to change di- rection of travel, he moves the lever upward to cause
the right signals to flash and downward to cause the
left signals to flash. After completion of a turn the system is deacti-
vated automatically. The cancellation switch in the
steering column sends a signal to a remote turn sig-
nal switch in the switch pod to cancel the turn signal
function. As the steering wheel returns to the
straight ahead position from a turn, a cancel cam
which is located on the steering wheel contacts a
cancel flipper located on the cancellation switch.
When the flipper is contacted by the cancel cam in
the proper rotational direction, the cancel switch
sends a signal to the remote turn signal switch. If only momentary signaling such as indication of a
lane change is desired, the switch is actuated to a
left or right intermediate detent position. In this po-
sition the signal lamps flash as described above, but
the switch returns to the OFF position as soon as the
lever is released. When the system is activated, 1 of 2 indicator
lamps mounted in the instrument cluster flashes in
unison with the turn signal lamps, indicating to the
driver that the system is operating.
HAZARD WARNING SYSTEM
The hazard warning system is actuated by a push
button located on the top of the steering column be-
tween the steering wheel and the instrument panel.
The hazard switch is identified with a double trian-
gle on top of the button. Push and release the button
to turn the hazard function ON or OFF. The button
will move out from the steering column in the ON
position and will remain in toward the column in the
OFF position.
CHIME FUNCTIONÐAC, AG, AJ AND AY
The chime will sound after the vehicle has traveled
a distance of 0.6 miles at a speed above 15 miles per
hour.
