REMOTE SWITCHES

DESCRIPTION

A remote radio switch option is available on models

equipped

with

the

AM/FM/CD/cassette/3-band

graphic equalizer (RAZ sales code) radio receiver and
the high-line Central Timer Module (CTM). (Refer to
8 - ELECTRICAL/ELECTRONIC CONTROL MOD-
ULES/BODY CONTROL/CENTRAL TIMER MODUL
- DESCRIPTION) for more information on this com-
ponent.

Two rocker-type switches (Fig. 14) are mounted in

the sides of the rear (instrument panel side) steering
wheel trim cover. The switch on the left spoke is the
seek switch and has seek up, seek down, and preset
station advance functions. The switch on the right
spoke is the volume control switch and has volume
up, and volume down functions. The switch on the
right spoke also includes a “mode” control that allows
the driver to sequentially select AM radio, FM radio,
cassette player or CD player. The two switches are
retained in mounting holes located on each side of
the rear steering wheel trim cover by four latches
that are integral to the switches.

The remote radio switches share a common steer-

ing wheel wire harness with the vehicle speed control
switches. The steering wheel wire harness is con-
nected to the instrument panel wire harness through
the clockspring. (Refer to 8 - ELECTRICAL/RE-
STRAINTS/CLOCKSPRING - DESCRIPTION) for
more information on this component.

OPERATION

The remote radio switches are resistor multiplexed

units that are hard wired to the high-line CTM
through the clockspring. The CTM monitors the sta-
tus of the remote radio switches and sends the
proper switch status messages on the J1850 data bus
network to the radio receiver. The electronic circuitry
within the radio is programmed to respond to these

remote radio switch status messages by adjusting the
radio settings as requested.

For diagnosis of the CTM or the J1850 data bus,

the use of a DRB scan tool and the proper Diagnostic
Procedures manual are recommended. For more
information on the features and control functions for
each of the remote radio switches, see the owner’s
manual in the vehicle glove box. For complete circuit
diagrams, refer to the appropriate wiring informa-
tion. The wiring information includes wiring dia-
grams, proper wire and connector repair procedures,
details of wire harness routing and retention, connec-
tor pin-out information and location views for the
various wire harness connectors, splices and grounds.

For complete circuit diagrams, refer to the appro-

priate 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

(4) Disconnect the 18-way wire harness connector

from the Central Timer Module (CTM). Check for
continuity between the radio control mux circuit cav-
ity of the remote radio switch wire harness connector
and a good ground. There should be no continuity. If
OK, go to Step 5. If not OK, repair the shorted radio
control mux circuit as required.

(5) Check for continuity between the radio control

mux circuit cavities of the remote radio switch wire
harness connector and the 18-way CTM wire harness
connector. There should be continuity. If OK, refer to
the proper Diagnostic Procedures manual to test the
CTM and the J1850 data bus. If not OK, repair the
open radio control mux circuit as required.

DESCRIPTION

STANDARD

The standard equipment speaker system includes

speakers in four locations. One full-range 16.5 centi-
meter (6.50 inch) diameter speaker is located in each
front door. There is also one full-range speaker
located in each rear cab side panel, 13.3 centimeter
(5.25 inch) diameter units for the standard cab mod-
els, and 16.5 centimeter (6.50 inch) diameter units
for the club cab models. On quad cab models, the
16.5

centimeter

(6.50

inch)

diameter

full-range

speaker units are located in each rear door, instead
of in the cab side panel.

PREMIUM

The optional premium speaker system features

Infinity model speakers in six locations. Each of the
standard speakers in the four speaker stereo system
are replaced with Infinity model speakers, and an
additional 6.9 centimeter (2.75 inch) diameter Infin-
ity dome tweeter is mounted high in the front door
trim panels. The premium speaker system also
includes an additional Infinity power amplifier. The
total available power of the premium speaker system
is about 120 watts.

OPERATION

STANDARD

Each of the four full-range speakers used in the

standard speaker system is driven by the amplifier
that is integral to the factory-installed radio receiver.
For complete circuit diagrams, refer to the appropri-
ate

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 connec-
tors, splices and grounds.

PREMIUM

The six Infinity speakers used in the premium

speaker system are all driven by the radio receiver
through an Infinity power amplifier. For complete cir-
cuit diagrams, refer to the appropriate wiring infor-
mation. The wiring information includes wiring
diagrams, proper wire and connector repair proce-
dures, details of wire harness routing and retention,
connector pin-out information and location views for
the various wire harness connectors, splices and
grounds.

TO TAKE THE PROPER PRECAUTIONS COULD

AND POSSIBLE PERSONAL INJURY.

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) Turn the ignition switch to the On position.

Turn the radio receiver on. Adjust the balance and
fader controls to check the performance of each indi-
vidual speaker. Note the speaker locations that are
not performing correctly. Go to Step 2.

(2) Turn the radio receiver off. Turn the ignition

switch to the Off position. Disconnect and isolate the
battery negative cable. Remove the radio receiver
from the instrument panel. If the vehicle is equipped
with the Infinity speaker package, also disconnect
the wire harness connectors at the power amplifier.
Check both the speaker feed (+) circuit and return (–)
circuit cavities for the inoperative speaker location(s)
at the radio receiver wire harness connectors for con-
tinuity to ground. In each case, there should be no
continuity. If OK, go to Step 3. If not OK, repair the
shorted speaker feed (+) and/or return (–) circuit(s) to
the speaker as required.

(3) If the vehicle is equipped with the Infinity

speaker package, go to Step 6. If the vehicle is
equipped with the standard speaker system, check
the resistance between the speaker feed (+) circuit
and return (–) circuit cavities of the radio receiver
wire harness connectors for the inoperative speaker
location(s). The meter should read between 2 and 28
ohms (speaker resistance). If OK, go to Step 4. If not
OK, go to Step 5.

(4) Install a known good radio receiver. Connect

the battery negative cable. Turn the ignition switch
to the On position. Turn on the radio receiver and
test the speaker operation. If OK, replace the faulty
radio receiver. If not OK, turn the radio receiver off,
turn the ignition switch to the Off position, discon-
