SWITCH-REMOTE RADIO

DESCRIPTION

Two rocker-type switches 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 vol-
ume 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, CD player or satellite radio.

OPERATION

The six switches in the two remote radio switch units are normally open, resistor multiplexed momentary switches
that are hard wired to the Instrument cluster through the clockspring. The instrument cluster sends a five volt ref-
erence 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 instrument cluster senses an input (voltage drop) from any one of the remote radio switches, it sends the
proper switch status messages on the Controller Area Network (CAN) data bus to the radio. The electronic circuitry
within the radio is programmed to respond to these remote radio switch status messages by adjusting the radio
settings as requested.

DIAGNOSIS AND TESTING

REMOTE SWITCHES

Any diagnosis of the Audio system should begin with the use of a scan tool and the appropriate Diagnostic
Service information.

AUDIO/VIDEO - SERVICE INFORMATION

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 ISOLATE THE BATTERY NEGATIVE (GROUND) CABLE, THEN WAIT TWO MIN-
UTES FOR THE AIRBAG SYSTEM CAPACITOR TO DISCHARGE BEFORE PERFORMING FURTHER DIAGNO-
SIS OR SERVICE. THIS IS THE ONLY SURE WAY TO DISABLE THE AIRBAG SYSTEM. FAILURE TO TAKE
THE PROPER PRECAUTIONS COULD RESULT IN ACCIDENTAL AIRBAG DEPLOYMENT AND POSSIBLE
PERSONAL INJURY.

1. Remove the remote radio switch(es) (1) and (2)

from the steering wheel (Refer to 8 - ELECTRICAL/
AUDIO/REMOTE SWITCHES - REMOVAL).

2. Use an ohmmeter to check the switch resistances

as shown in the Remote Radio Switch test table. If
the remote radio switch resistances are not as indi-
cated, replace the inoperative switch.
