Troubleshooting Of The Speakers 

CAUTION: When handling the speakers:
  • Do not cause shock to the speakers by dropping or throwing them.
  • Be careful not to drop water and oil on the speakers.
  • Use caution to handle the speaker because diaphragm made of paper is easily torn by impact or external force.
  • Audio system tuning may cause damage to the speakers. The modified speakers are not covered by the manufacturer's warranty.
  1. Basic inspection

    Loosen the screws to rule out the interference from the body trims and surrounding parts and then remove the speaker.

    After removing the speaker, check the sound quality of the speaker with the connector plugged in.

  2. Inspection for each cause
    1. Abnormal vibration
      • Make sure the mounting screws are properly tightened before replacing the speaker.
      • Reinstall the speaker and check that the symptom is resolved.
      • If the symptom does not disappear, replace the speaker with a new one.
    2. Noise
      • Check that the speaker connector is properly connected and reinstall the connector if necessary.
      • If noises occur in the radio mode, turn to the CD player mode.
      • If noises occur in both modes, replace the speaker with a new one.
        NOTE: If noises occur only in the radio mode, the poor radio reception is the cause so do not replace the speaker.
    3. Poor working
      • Check the plus (+) and negative (-) speaker terminals using an ohmmeter.
      • If resistance is measured at the specified value displayed below, the speaker operation is normal.
      • If the measured resistance is different from the specified value, replace the speaker.
