How to Check the Audio System Condition

The audio system has a self-diagnostic function to help find problems with the audio system. To run the self-diagnostic function, do the following:

NOTE:

Not all self-diagnostic functions appear on all models.
There may be other self-diagnostic functions that are for factory use only.
The self-diagnostic function does not find every problem with the audio system. Check any official Honda service website for more information about the audio system.

Turn the ignition switch to ON (II), or press the engine start/stop button to select the ON mode. Make sure the audio system is turned off.
Push and hold the preset No. 1 and No. 6 buttons.
While holding the buttons, push the VOLUME/POWER knob to on.
Release the buttons, and the self-diagnosis begins.
