Radio/Stereo: Description and Operation

AUDIO SYSTEM
The audio system on the 2002 PL consists of a radio that communicates over the PCI bus. Each radio system comes equipped with a standard premium 6 speaker system. The speakers are located in the instrument panel, the front doors and the rear "D" pillars. The instrument panel speakers are a tweeter type speaker for high frequency. The front door speakers are a woofer/midrange type speaker. The rear "D" pillar speakers are a full range type speaker. If one of the speaker circuits experiences a short, the other speakers on that output channel will also shut down until the circuit is repaired. The radio will also set a trouble code, which the DRB III can display.

There are three different system combinations available on the PL models. The available radio options are:
- AM/FM Cassette with CD Changer Control (RBB Sales Code)
- AM/FM CD with CD Changer Control (RBK Sales Code)
- 4 Disc CD Changer In-Dash - used with Radio CD Changer Controls (RDW Sales Code)

The in-dash CD-changer is designed to fit into the existing cubby bin in the center stack. This new cartridge-less CD-changer is controlled by your radio, and allows you to individually load up to four discs at one time. However, due to its compact design, the CD-changer can only carry out one operation at a time. For example you can not load a new disc while playing another at the same time. Each operation happens sequentially

The radio unit installed with your system provides control over all features of the CD-changer with the exception of the CD load and eject functions, which are controlled by buttons located on the front of the CD-changer. The radio also supplies the power, ground, PCI Bus, left and right speaker output through a single DIN cable. All features you would expect , such as Disc Up/Down, Track Up/Down, Random and Scan are controlled by the radio, which also displays all relevant CD-changer information on the radio display.

The CD-changer contains a Load/Eject button and an indicator light for each of the four disc positions. The individual light indicates whether a CD is currently loaded in that particular chamber of the CD-changer. Pressing the individual Load/Eject button for a particular chamber will eject a disc currently present in the chamber. If the chamber is currently empty, actuating the Load/Eject button will position that chamber to receive and load a new disc in that chamber.

The vehicles are equipped with an Interior Ignition Off Draw (IOD) fuse in the Power Distribution Center located in the engine compartment. After the Interior (IOD) fuse or battery has been disconnected, the clock will require resetting. The radio station presets have a non-volatile memory and will retain the preset stations after a battery disconnect.

Operating instructions for the factory installed audio systems can be found in the Owner's Manual provided with the vehicle.

RADIO NOISE SUPPRESSION COMPONENTS
The vehicle has the following noise suppression components which, if disconnected, may interfere with radio reception:
- Cylinder head to dragon's head to body ground strap Y-strap).
- Battery tray to transmission ground strap (automatic transmission only).
- Hood hinge straps (left and right).
- Noise suppression capacitor.
- Strut to body ground straps (left and right).
- Exhaust to body ground strap.

Resistive type spark plug cables in the high tension circuit of the ignition system complete the interference suppression. Faulty or deteriorated spark plug wires should be replaced.
