RADIO

DESCRIPTION

Available radios for this vehicle include:
• AM/FM/cassette with CD changer control fea-

ture (RBB sales code)

• AM/FM/CD with CD changer control feature

(RBK sales code)

• AM/FM/cassette/CD (RBY sales code) - export

only

• AM/FM/cassette/CD with CD changer control

feature (RAD sales code) - export only

OPERATION

The radio receiver operates on ignition switched

battery current that is available only when the igni-
tion switch is in the On or Accessory positions. The
electronic digital clock function of the radio operates
on fused battery current supplied through the IOD
fuse, regardless of the ignition switch position.

For more information on the features, setting pro-

cedures, and control functions for each of the avail-

able factory-installed radio receivers, refer to the
owner’s manual.

REMOVAL

(1) Disconnect and isolate the battery negative

cable.

(2) Remove instrument panel center bezel (Refer to

23 - BODY/INSTRUMENT PANEL/INSTRUMENT
PANEL CENTER BEZEL - REMOVAL).

(3) Remove four mounting screws on the radio and

pull out of instrument panel (Fig. 4).

CAUTION: Pulling the antenna cable straight out of
the radio without pulling on the locking antenna
connector could damage the cable or radio.

(4) Disconnect the antenna cable by pulling the

locking antenna connector away from the radio (Fig.
5).

(5)

Disconnect wire harness connector from radio.

(6) Remove radio from vehicle.

RADIO NOISE SUPPRESSION
COMPONENTS

DESCRIPTION

The vehicle has the following noise suppression

components which, if disconnected, may interfere
with radio reception:

• Cylinder head to body ground strap (Y-strap).

• Battery tray to transmission ground strap (auto-

matic transmission only).

• Hood hinge straps (left and right).

• Noise suppression capacitor.

• Strut to body ground straps (left and right).
Resistive type spark plug cables in the high ten-

sion circuit of the ignition system complete the inter-
ference suppression. Faulty or deteriorated spark
plug wires should be replaced.

OPERATION

There are two common strategies that can be used

to suppress Radio Frequency Interference (RFI) and
ElectroMagnetic Interference (EMI) radio noise. The
first suppression strategy involves preventing the
production of RFI and EMI electromagnetic signals
at their sources. The second suppression strategy
involves preventing the reception of RFI and EMI
electromagnetic signals by the audio system compo-
nents.

The use of braided ground straps in key locations

is part of the RFI and EMI prevention strategy.
These ground straps ensure adequate ground paths,
particularly for high current components such as
many of those found in the starting, charging, igni-
tion, engine control and transmission control sys-
tems. An insufficient ground path for any of these
high current components may result in radio noise
caused by induced voltages created as the high cur-
rent seeks alternative ground paths through compo-
nents or circuits intended for use by, or in close
proximity to the audio system components or circuits.

Preventing the reception of RFI and EMI is accom-

plished by ensuring that the audio system compo-
nents are correctly installed in the vehicle. Loose,
corroded or improperly soldered wire harness connec-
tions, improperly routed wiring and inadequate audio

system component grounding can all contribute to
the reception of RFI and EMI. A properly grounded
antenna body and radio chassis, as well as a shielded
antenna coaxial cable with clean and tight connec-
tions will each help reduce the potential for reception
of RFI and EMI.

SPEAKER

DESCRIPTION

The standard equipment speaker system includes

speakers in six locations. One 2.5 centimeter (1.0
inch) diameter speaker is installed on each end of the
instrument panel top pad. One 16.5 centimeter (6.5
inch) full-range speaker is located in each front door.
There is also two full-range 15.2 X 22.8 centimeter (6
X 9 inch) diameter full-range speakers located in the
rear shelf.

OPERATION

Two wires connected to each speaker, one feed cir-

cuit (+) and one return circuit (–), allow the audio
output signal electrical current to flow through the
voice coil. For complete circuit diagrams, refer to the
appropriate wiring information. The wiring informa-
tion includes wiring diagrams, proper wire and con-
nector repair procedures, details of wire harness
routing and retention, connector pin-out information
and location views for the various wire harness con-
nectors, splices and grounds.

DIAGNOSIS AND TESTING - SPEAKER

Any diagnosis of the Audio system should

begin with the use of the DRB III

t diagnostic

tool. For information on the use of the DRB
III

t, refer to the appropriate Diagnostic Service

Manual.

Refer to the appropriate wiring information.

WARNING:

DISABLE

THE

AIRBAG

SYSTEM

BEFORE ATTEMPTING ANY STEERING WHEEL,
STEERING COLUMN, SEAT BELT TENSIONER, SIDE
AIRBAG, OR INSTRUMENT PANEL COMPONENT
DIAGNOSIS OR SERVICE. DISCONNECT AND ISO-
LATE THE BATTERY NEGATIVE (GROUND) CABLE,
THEN WAIT TWO MINUTES FOR THE AIRBAG SYS-
TEM CAPACITOR TO DISCHARGE BEFORE PER-
FORMING FURTHER DIAGNOSIS OR SERVICE. THIS
IS THE ONLY SURE WAY TO DISABLE THE AIRBAG
SYSTEM. FAILURE TO TAKE THE PROPER PRE-
CAUTIONS COULD RESULT IN ACCIDENTAL AIR-
BAG DEPLOYMENT AND POSSIBLE PERSONAL
INJURY.

RADIO (Continued)

CAUTION: The speaker output of the radio is a
“floating ground” system. Do not allow any speaker
lead to short to ground, as damage to the radio
may result.

(1) If all speakers are inoperative, check the fuses

in the fuse block. If OK, go to Step 2. If not OK,
repair the shorted circuit or component as required
and replace the faulty fuse.

(2) Turn the ignition switch to the ON position.

Turn the radio receiver ON. Adjust the balance and
fader control controls to check the performance of
each individual speaker. Note the speaker locations
that are not performing correctly. Go to Step 3.

(3) Turn the radio receiver OFF. Turn the ignition

OFF. Disconnect and isolate the battery negative
cable. Remove the radio receiver.

(4) Check both the speaker feed (+) circuit and

return (-) circuit cavities for the inoperative speaker
at the radio receiver wire harness connector for con-
tinuity to ground. There should be no continuity. If
OK, go to Step 5. If not OK, repair the shorted
speaker feed (+) and/or return (-) circuits(s) to the
speaker as required.

(5) Disconnect wire harness connector at the inop-

erative speaker. Check for continuity between the
speaker feed (+) circuit cavities of the radio receiver
wire harness connector and the speaker wire harness
connector. Repeat the check between the speaker
return (-) circuit cavities of the radio receiver wire
harness connector and the speaker wire harness con-
nector. In each case, there should be continuity. If
OK, replace the faulty speaker. If not OK, repair the
open speaker feed (+) and/or return (-) circuits(s) as
required.
