8F - 2 AUDIO SYSTEMS
DESCRIPTION AND OPERATION (Continued)
CD/3-band graphic equalizer (RBR sales code), or an
AM/FM/CD/cassette/3-band graphic equalizer (RAZ
sales code).
All factory-installed radio receivers are stereo Elec-
tronically Tuned Radios (ETR) and include an elec-
tronic digital clock function.
All factory-installed radio receivers, except the
RAS model, communicate on the Chrysler Collision
Detection (CCD) data bus network through a sepa-
rate two-way wire harness connector. The CCD data
bus network allows the sharing of sensor informa-
tion. This helps to reduce wire harness complexity,
internal controller hardware, and component sensor
current loads. At the same time, this system provides
increased reliability,
allows the addition of many new feature capabilities.
In addition, radios connected to the CCD data bus
have several audio system functions that can be diag-
nosed using a DRB scan tool. Refer to the proper
Diagnostic Procedures manual for more information
on DRB testing of the audio systems.
The radio can only be serviced by an authorized
radio repair station. Refer to the latest Warranty Pol-
icies and Procedures manual for a current listing of
authorized radio repair stations.
For more information on radio features, setting
procedures, and control functions refer to the owner's
manual in the vehicle glove box.
