Models:
All '98 Models
Introduction
1998 deluxe and premium grade audio systems are equipped with an Audio Visual Communication - Local Area Network (AVC-LAN) that standardizes the audio, visual, switch, and communication data used between the radio, amplifier, cassette player, and CD player/changer. The AVC-LAN standards allow diagnostic functions and easy product interchangeability.
AVC-LAN Diagnostics
The AVC-LAN system identifies each audio component by a Code Number and the probable cause of the condition by a Diagnostic Trouble Code. These codes can be accessed by the following procedure:
Activate the Diagnostic Mode
1. Set the ignition key to the "ON" position and turn the radio "OFF".
2. While pressing the "1 " and "6" buttons, press the "CD" button 3 times. The Code Number, which identifies the audio components, will display.
^ Display the Code Numbers of other audio components by using the "TUNE UP" or "TUNE DOWN" button.
Activate the System Check Mode
3. Press the "1" button to activate the System Check Mode. The system will perform a self-diagnosis, store up to six error codes, and display the first error code.
^ Display other error codes by using the "TUNE UP" or "TUNE DOWN" button.
^ When no errors are detected, "00" will display.
^ Press "6" to exit this mode.
Activate the Diagnostic Memory Mode
4. Press the "2" button to activate the Diagnosis Memory Mode. The results of the self-diagnosis performed on the radio and other components attached to the radio are stored. Up to six error codes are stored in memory and the system displays the first error code.
^ The other error codes can be displayed by using the "TUNE UP" or "TUNE DOWN" button.
^ When no errors are detected, "00" will display.
^ Press "6" to exit this mode.
Erasing the Diagnostic Memory
5. Pressing the "5" button for 2 seconds will erase the memory.
Exiting the Diagnostic Mode
6. Exit the diagnosis mode by pressing and holding the "CD" button for 2 seconds or by turning the key to the "OFF" position.
