WARNING: This page is about a different car, the 2008 Honda Pilot, 2007 Honda Pilot, and 2006 Honda Pilot. However, it is still accessible from the selected car via links, so may be relevant.

NOTE: Check the vehicle battery condition first.

Turn the ignition switch ON (II).
Turn on the audio unit and check for sound in each mode (AM, FM, XM, and disc).
Is there sound from the speakers, and is the sound quality normal in each mode?

YES - Intermittent failure. The system is OK at this time. Check for loose connection at the audio unit, amplifier, and each speaker.

NO - Speakers all work, sound quality is poor.
- If sound is poor only with XM radio, or the XM radio does not function, go to poor or no sound with XM radio (see POOR OR NO SOUND WITH XM RADIO ).
- If the sound is poor only with AM or FM, go to poor radio reception or interference (see SYMPTOM TROUBLESHOOTING ).
- If sound is poor in all modes, go to sound quality diagnosis (see SOUND QUALITY DIAGNOSIS ).
