Sound Balance Test

WARNING: This page is about a different car, the 2013 Acura MDX, 2012 Acura MDX, 2011 Acura MDX, and 2010 Acura MDX. However, it is still accessible from the selected car via links, so may be relevant.

Do this test to identify a faulty channel or speaker.

  1. Insert the audio diagnostic CD (T/N 07AAZ-SDBA100) into the audio unit or the audio-navigation unit.
  2. Confirm the bass and treble are set to the center positions.
  3. Play track No. 3 (pink noise) at a normal, or slightly higher than normal, volume level.
  4. A static type sound should be heard through all speakers.
  5. Insert the audio diagnostic CD (T/N 07AAZ-SDBA100) into the audio unit or the audio-navigation unit of a known-good vehicle.
  6. Set the bass and treble to the center positions.
  7. Play track No. 3 (pink noise) all the same level as was played in step  3.
  8. Compare the sounds made by the two vehicles.
    • If the sounds made by the two vehicles are very similar, go to the FREQUENCY SWEEP TEST .
    • If the sound does not have as much bass, check the subwoofer and circuit.
    • If the sound does not have enough hiss, check the tweeters and their circuits.
