Individual Speaker Test

Do this test to identify a faulty speaker.

1. Insert the audio Diagnostic CD (07AAZ-SDBA100) into the audio-navigation unit or the audio unit

2. Play track No. 30 (steady 300 Hz tone) at a normal, or slightly higher than normal, volume level

3. Listen to each speaker for poor sound compared to the other speakers. Use the audio-navigation unit's or the audio unit's fader and balance settings to help isolate the channel with the problem.

If the sound quality produced by a specific speaker is poor, substitute it with a known-good speaker. If the poor sound quality continues, go to Sound Balance Test.
If the sound quality is OK, go to Sound Balance Test.
