- Do this test to compare overall sound quality, imaging, and dynamics between the customer's vehicle and a known-good vehicle. Only use a vehicle of the same model and trim level for this test.
- Make sure the vehicle is using only OEM speakers.
- In the customer's vehicle, set the bass, treble, fader, and balance settings to the customer's normal settings that were written down before beginning testing.
- Insert the audio diagnostic CD (T/N: 07AAZ-SDBA100) into the audio-navigation unit or the audio unit.
- Play tracks No. 7 to 12 (sound quality, midland, dynamics, and imaging demonstration tracks) at a normal, or slightly higher than normal, volume level. Write down the volume setting used.
- Listen to areas of the track that stand out as being either very clear, or poorer than other areas of the track.
- In a known-good vehicle, insert the audio diagnostic CD (T/N: 07AAZ-SDBA100) into the audio-navigation unit or the audio unit.
- Play the tracks at the same volume level and the same bass, treble, balance, and fader settings as used in step 3 in the customer's vehicle.
- Listen to the same area of the track that stood out as being either very clear or poorer than other areas of the track.
- Compare the customer's vehicle's sound quality results to the known-good vehicle's results.
- If the sound quality in the customer's vehicle is comparable to the sound quality in the known-good vehicle, then the customer's vehicle is operating as designed.
- If the sound quality is not comparable, check these items in order:
- Loose or improperly installed speakers or other hardware that may become excited by the vibrations generated by the speakers
- Poor power or ground to the stereo amplifier (with premium sound system)
- Damaged speaker(s)
- Faulty stereo amplifier (with premium sound system)
- Faulty audio-navigation unit
- Faulty audio unit
