Radio/Stereo: Description and Operation
AUDIOAn audio system is available factory-installed equipment on this model. Several combinations of radio receivers and speaker systems are offered.
The audio system includes the following components:
- Antenna
- Compact disc changer (if equipped)
- Radio noise suppression components
- Radio receiver
- Speakers
Certain functions and features of the audio system rely upon resources shared with other electronic modules in the vehicle over the Programmable Communication Interface (PCI) bus network. The data bus network allows the sharing of sensor information. For diagnosis of these electronic modules or of the data bus network, the use of a DRB III scan tool and the proper Diagnostic Procedures manual are recommended.
The audio system components are designed to provide audio entertainment and information through the reception, tuning and amplification of locally broadcast radio signals in both the Amplitude Modulating (AM) and Frequency Modulating (FM) commercial frequency ranges.
The audio system components operate on battery current received through a fuse in the Power Distribution Center (PDC) on a fused ignition switch output (RUN/ACC) circuit so that the system will only operate when the ignition switch is in the Run or Accessory positions.
Refer to the owner's manual for more information on the features, use and operation of each of the available audio systems.
RADIO
Available factory-installed radio receivers for this model include:
- AM/FM/cassette with CD changer control feature (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 communicate on the Programmable Communications Interface (PCI) data bus network. All factory-installed receivers 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 Warranty Policies and Procedures manual for a current listing of authorized radio repair stations.
The radio receiver operates on ignition switched battery current that is available only when the ignition 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 procedures, and control functions for each of the available factory-installed radio receivers, refer to the owner's manual.
