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. |
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 shown below, the speaker operation is normal. |
–
| If the measured resistance is different from the specified value, replace the speaker. |
