Radio/Stereo: Description and Operation
AUDIOThe audio system on the 2001 PL consists of a radio that communicates over the PCI bus. There are two different system combinations available on the PL models.
The available radio options are:
- AM/FM Cassette with CD Changer Controls and Display
- CD/4 Disc Changer In-Dash (used with Radio CD Changer Controls
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. Depending on the manufacture, some systems will have Front/Rear output system and others will have a Left/Right output system. 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, indicating which output is effected.
Operating instructions for the factory installed audio systems can be found in the Owner's Manual provided with the vehicle.
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 nonvolatile memory and will retain the preset stations after a battery disconnect.
RADIO NOISE SUPPRESSION COMPONENTS
The radio utilizes a ground wire plugged on to a blade terminal and is bolted to the radio chassis. Both connector and terminal should be securely attached. 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.
