AUDIO SYSTEM DIAGNOSIS TABLE

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 minutes for the airbag system capacitor to discharge
before performing further diagnosis 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.

ANTENNA BODY & CABLE

DESCRIPTION

ANTENNA BODY AND CABLE

DOMESTIC

All models feature a roof-mounted active mast antenna. This is a combination antenna that receives both
AM/FM and satellite digital audio. The antenna cables are routed along the left side of the under the headliner,
down the A-pillar to the instrument panel. For antenna removal. See REMOVAL. For antenna installation . See
INSTALLATION.

OPERATION

ANTENNA BODY AND CABLE

The antenna body and cable connects the antenna mast to the radio. The radio antenna is an electromagnetic
circuit component used to capture radio frequency signals that are broadcast by local commercial radio stations
in both the Amplitude Modulating (AM) and Frequency Modulating (FM) frequency ranges. These
electromagnetic radio frequency signals induce small electrical modulations into the antenna as they move past
the mast. The antenna body transfers the weak electromagnetic radio waves induced into the antenna into the
center conductor of the flexible primary antenna coaxial cable. The braided outer shield of the antenna coaxial
cable is grounded through both the antenna body and the radio chassis, effectively shielding the radio waves as
they are conducted to the radio. The radio then tunes and amplifies the weak radio signals into stronger
electrical signals in order to operate the audio system speakers.
