DESCRIPTION AND OPERATION
RADIO OPERATION
There are two audio systems offered on this vehi-
cle. The base system uses six speakers and a stan-
dard antenna. The optional system has six speakers,
power amplifier, and a power antenna.
Both systems are powered by a 10 amp fuse
located in cavity 14 of the junction block on circuit
X12. This fuse is HOT when the ignition switch is in
the ACCESSORY or RUN position.
The A31 circuit, which receives it's power from the
ignition switch, on circuit A1, is protected by a 20
amp fuse located in cavity 8 of the Power Distribu-
tion Center (PDC).
Both the standard and optional radios use an
external case ground. This case ground attaches to
the rear of the radio and the instrument panel. There
is also a ground for the radio provided on circuit Z1.
This circuit attaches to the rear of the radio and ter-
minates at the instrument panel ground.
RADIO MEMORY
Both the base and premium systems use the M1
circuit to maintain radio memory. This circuit is con-
nected to the battery through the Power Distribution
Center (PDC), and protected by a 10 amp Ignition-
Off Draw (IOD) fuse. The M1 circuit is used to sup-
ply power to the Body Control Module (BCM), Power
Mirrors, and the Power Door Locks. This fuse is also
used in several other circuits, refer to section 8W-12
for additional information on the IOD fuse. The IOD
fuse is removed during vehicle shipping to prevent
excessive battery draw.
RADIO ILLUMINATION
When the parking lamps or the headlamps are ON,
circuits E2 and L7 are used to power the radio illu-
mination lamps. Circuit E2 is controlled by the Body
Control Module (BCM). Circuit L7 is controlled by
the park lamp switch.

CCD BUS
The CCD Bus and the universal data link connec-
tor are used for access to the diagnostic capabilities
of the radio. Circuits D1 and D2 are used.
The D1 circuit is used for CCD (+) and circuit D2
is used for CCD (-).
SPEAKERS (BASE SYSTEM)
Circuits X53 and X87 are the feeds to the left front
door and instrument panel speakers. Circuits X55
and X85 are the returns from the speakers to the
radio.
Circuits X54 and X82 are the feeds to the right
front door and instrument panel speaker. Circuits
X56 and X80 are the returns from the speakers to
the radio.
Circuit X51 is the feed to the left rear speaker. Cir-
cuit X57 is the return from the speaker to the radio.
Circuit X52 is the feed to the right rear speaker.
Circuit X58 is the return from the speaker to the
radio.
POWER AMPLIFIER
The power amplifier is used in the premium sys-
tem only. It is placed between the radio and the
speakers. The feed for the amplifier is provided on
the F30 circuit.
The F30 circuit is protected by a 20 amp fuse
located in cavity 8 of the junction block. Circuit F30
is spliced and provides power to the horns and the
cigar lighter. Ground is provided on the Z1 circuit
and terminates at the instrument panel left side
cowl.
An additional feed input to the power amplifier is
on circuit X60. This circuit is HOT when the radio is
in the ON position.
Circuits P5 and P6 also connect to the power
amplifier. These circuits are spliced in with the
power top switch.
