DIAGNOSIS AND TESTING - POWER ANTENNA
- EXPORT

Refer to the appropriate wiring information. The

wiring information includes wiring diagrams, proper
wire and connector repair procedures, further details
on wire harness routing and retention, as well as
pin-out and location views for the various wire har-
ness connectors, splices and grounds.

(1) Using

ohmmeter,

check

for

continuity

between the antenna body and ground. There should
be no measurable resistance. If OK, go to Step 2. If
not, repair or clean ground as necessary.

(2) Disconnect the wire harness connector at the

antenna. Check for battery voltage at pin A1. If OK,
go to Step 3. If not, check circuit fuse or check for a
shorted or open wire.

(3) With the ignition in the ON or ACC position,

turn radio ON and check for battery voltage at pin
A2. If OK, replace power antenna (Refer to 8 - ELEC-
TRICAL/AUDIO/ANTENNA - REMOVAL). If not,
check for a shorted or open wire.

REMOVAL

(1) Disconnect and isolate the battery negative

cable.

(2) Disconnect drain tube.
(3) Disconnect electrical connector.
(4) Disconnect antenna cable.
(5) Remove mounting bolts from antenna (Fig. 3).
(6) Pull antenna through grommet in quarter

panel.

INSTALLATION

(1) Push antenna up through grommet in quarter

panel.

(2) Install mounting bolts to antenna. Tighten to

12 N·m (110 in. lbs.).

(3) Connect antenna cable.
(4) Connect electrical connector to antenna.
(5) Connect drain tube.
(6) Install ground strap (if equipped) and fastener.

Tighten to 12 N·m (110 in. lbs.).

(7) Connect battery negative cable.

REMOTE SWITCHES

DESCRIPTION

Remote radio control switches are rocker-type

switch units (Fig. 4) are mounted in the upper spoke
covers of the rear (instrument panel side) steering
wheel trim cover. The switch unit on the left side is
the seek switch and has seek up, seek down, and pre-
set station advance switch functions. The switch unit
on the right side is the volume control switch and
has volume up, volume down, and mode advance
switch functions.

The two remote radio switch units are each

retained in a mounting hole located on opposite sides
of the rear steering wheel trim cover by four integral
snap features. A plastic bracket on the back of each
switch unit provides additional support for the unit
by extending towards the center of the steering
wheel where it is clamped between the steering
wheel armature and the steering wheel rear trim
cover mounting boss by the trim cover mounting
screw.

The two remote radio switch units share a common

steering wheel wire harness with the vehicle speed
control switches. The steering wheel wire harness is
connected to the instrument panel wire harness
through the clockspring.

OPERATION

The six switches in the two remote radio switch

units

are

normally

open,

resistor

multiplexed

momentary switches that are hard wired to the Body
Control Module (BCM) through the clockspring. The
BCM sends a five volt reference signal to both switch
units on one circuit, and senses the status of all of
the switches by reading the voltage drop on a second
circuit.

When the BCM senses an input (voltage drop) from

any one of the remote radio switches, it sends the
proper switch status messages on the Programmable
Communication Interface (PCI) data bus network to
the radio receiver. The electronic circuitry within the
radio receiver is programmed to respond to these
remote radio switch status messages by adjusting the
radio settings as requested. For diagnosis of the
BCM or the PCI data bus, the use of a DRB III scan
tool and the proper Body Diagnostic Procedures man-
ual are recommended.

DIAGNOSIS AND TESTING - REMOTE
SWITCHES

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. The

wiring information includes wiring diagrams, proper
wire and connector repair procedures, details of wire
harness routing and retention, connector pin-out
information and location views for the various wire
harness connectors, splices and grounds.

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.

(1) Disconnect and isolate the battery negative

cable. Remove the remote radio switch(es) (Fig. 5)
from the steering wheel.

(2) Use an ohmmeter to check the switch resis-

tances as shown in the Remote Radio Switch Test
table. If the remote radio switch resistances check
OK, go to Step 3. If not OK, replace the faulty
switch.

(3) Reconnect the battery negative cable. Turn the

ignition switch to the ON position. Check for 5 volts
at the radio control mux circuit cavities of the steer-
ing wheel wire harness connectors for both remote
radio switches. If OK, go to Step 4. If not OK, repair
the open or shorted radio control mux circuit to the
Body Control Module (BCM) as required.

(4) Disconnect and isolate the battery negative

cable. Disconnect the 18-way instrument panel wire
harness connector from the BCM. Check for continu-
ity between the remote radio switch ground circuit
cavities of the steering wheel wire harness connec-
tors for both remote radio switches and a good
ground. There should be no continuity. If OK, go to
Step 5. If not OK, repair the shorted remote radio
switch ground circuit to the BCM as required.

(5) Check for continuity between the remote radio

switch ground circuit cavities of the steering wheel
wire

harness

connectors

for

both

remote

radio

switches and the 18-way instrument panel wire har-
ness connector for the BCM. There should be conti-
nuity. If OK, refer to the proper Body Diagnostic
Procedures manual to test the BCM and the PCI
data bus. If not OK, repair the open remote radio
switch ground circuit as required.

RADIO

DESCRIPTION

Available factory-installed radio receivers for this

model include:

• AM/FM/cassette/CD (RAZ sales code)

• 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

All factory-installed radio receivers can communi-

cate on the Programmable Communications Interface
(PCI) data bus network. All factory-installed receiv-
ers are stereo Electronically Tuned Radios (ETR) and
include an electronic digital clock function.

These radio receivers can only be serviced by an

authorized radio repair station. See the latest War-
ranty Policies and Procedures manual for a current
listing of authorized radio repair stations.

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.

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

(6) Disconnect the antenna cable by pulling the

locking antenna connector away from the radio (Fig.
8).
