(8) Upon establishing that the fault is in the an-
tenna assembly, it may be traced to one or more of
the following conditions: (a) Broken lead-in wire or shielding.
(b) Grounded lead-in wire or mast assembly.
(c) Moisture in support tube or lead-in assembly.
(d) Poor connection at antenna lead-in assembly
or shielding ground.
REMOVAL
(1) Disconnect battery negative cable.
(2) Remove the right front fender splash shield fas-
teners and pull shield away from the wheel housing.
(3) Disconnect motor leads at the connector (Fig. 15).
(4) Disconnect lead-in cable by twisting at connec-
tor (Fig. 17).
(5) Remove one screw attaching antenna to an-
tenna brace (Fig. 18). (6) Remove cap nut on fender surface with An-
tenna Nut Wench C-4816 (Fig. 11). (7) Remove antenna from under fender.
INSTALLATION
(1) Position antenna under fender and through
fender adapter. (2) Replace and tighten cap nut to 14 N Im (125 in.
lbs.) torque with Antenna Nut Wench C-4816.
(3) Position antenna on antenna brace and install at-
taching screw. Tighten to 4 N Im (40 in. lbs.) torque.
(4) Connect antenna lead at twist connector.
(5) Connect motor leads at connector.
(6) Position right front fender splash shield and in-
stall attaching fasteners. (7) Connect negative battery cable and test opera-
tion of antenna.
POWER ANTENNA MAST
REMOVAL
(1) Remove cap nut using Antenna Nut Wrench
C-4816. (2) Install temporary nut provided with the re-
placement mast. (3) Turn ignition key to ACCESSORY position and
turn on radio. (4) While the mast is moving up pull upward to re-
move mast and drive rod from the mast tube.
INSTALLATION
(1) Insert new drive rod into mast tube with drive
teeth toward antenna motor (Fig. 19).
(2) Turn off radio and guide mast into tube. The
mast may not be fully lowered when first installed. (3) Replace the temporary nut with the original
cap nut and tighten to 14 N Im (125 in. lbs.) torque
using Antenna Nut Wench C-4816. (4) Turn radio on and off to extend and retract an-
tenna. Mast should be fully lowered after recycling.

INFINITY REMOTE AMPLIFIER
The AC and AY amplifier is located in the trunk
on the rear seat bulkhead and the behind rear trim
panel. The AJ amplifier is located in the trunk on the left
wheel housing extension behind the side trim panel. When the radio system is ON, and all or some
speakers are not operating or have a noise distortion
refer to the diagnostic tests. The amplifier has the
terminal connections list on the case (Fig. 34).
CONDITION: NOISE DISTORTION IN ALL SPEAKERS
² Check battery voltage for 11 Volts or more
² Check amplifier connectors and wires for proper
connection and continuity
² If OK, check radio, refer to Audio Diagnostic
Charts.
² If OK, replace amplifier
CONDITION: ELECTRICAL NOISE
DISTORTION ONE SPEAKER
Remove output signal connector from amplifier and
check for short to ground on the speaker with the
distortion. Refer to Fig. 34 for the appropriate pin
numbers.
² If shorted to ground disconnect speaker connector
and recheck the amplifier connector for short to
ground.
² If still shorted to ground repair wires. If not
shorted to ground, replace speaker.

² If no short to ground at connector, check speaker
resistance at amplifier connector for an reading of
three to five ohms.
² If resistance is OK, refer to Radio Diagnosis. If ra-
dio checks OK, replace amplifier.
² If resistance is less than three ohms check
speaker. Check across the speaker connector if less
than three ohms replace speaker. If resistance is OK
repair wires
CONDITION: MECHANICAL NOISE DISTORTION
² Check trim for loose parts and speaker attach-
ments for buzzes
² Remove speaker still connected and listen for dis-
tortion. Distortion replace speaker.
CONDITION: ONE SPEAKER NON-OPERATIVE
² Remove output signal connector from amplifier
and check for three to five ohms resistance to the
non-operative speaker. Refer to Fig. 34 for the appro-
priate pin numbers.
² If resistance is less than three ohms, test speaker
for resistance.
² If OK repair wire. If not replace speaker.
CONDITION: ALL SPEAKERS NON-OPERATIVE
²Check radio for being ON, are the display lights
on
² Radio not ON, refer to Radio Diagnosis
² Check Amplifier Connectors and wires for proper
connection
² Check pin 9 and pin 27 for battery voltage
² If voltage OK replace amplifier ²
If pin 27 has battery voltage and pin 9 has 0 volt-
age. Refer to Power Antenna Diagnosis and test volt-
age at antenna relay.
² If pin 9 has battery voltage and pin 27 has 0 volt-
age. Check pin 27 for short to ground.
² If shorted to ground repair wire
² If no short to ground check fuse cavity number 16
for blown fuse.
² If fuse blows again replace amplifier
RELAY/CHOKEÐINFINITY SPEAKER
If the audio system is lacking bass, check for con-
tinuity across the relay and choke connectors. If no
continuity, replace relay/choke assembly (Fig. 35).

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.
