Related To Audio
WARNING: This page is about a different car, the 2011 Nissan 370Z. However, it is still accessible from the selected car via links, so may be relevant.
- The majority of the audio malfunctions are the result of outside causes (bad CD, electromagnetic interference, etc.). Check the symptoms below to diagnose the malfunction.
- The vehicle itself can be a source of noise if noise prevention parts or electrical equipment is malfunctioning. Check that noise is caused and/or changed by engine speed, ignition switch turned to each position, and operation of each piece of electrical equipment. Then determine the cause.
NOTE:
- CD-R is not guaranteed to play because they can contain compressed audio (MP3, WMA) or could be incorrectly mastered by the customer on a computer.
- Check that the CDs carry the Compact Disc Logo. If not, the disc is not mastered to the red book Compact Disc Standard and may not play.
PROBLEM SYMPTOMS
| Symptoms | Cause and Counter measure |
|---|---|
| Cannot play | Check that the CD was inserted correctly. |
| Check that the CD is scratched or dirty. | |
| Check that there is condensation inside the player, and if there is, wait until the condensation is gone (about 1 hour) before using the player. | |
| The player will play correctly after it returns to the normal temperature if there is a temperature increase error. | |
| Only the music CD files (CD-DA data) will be played if there is a mixture of music CD files (CDDA data) and MP3/WMA files on a CD. | |
| Files with extensions other than ".MP3", ".WMA", ".mp3", or ".wma" cannot be played. | |
| Check that the finalization process, such as session close and disc close, is done for the disc. | |
| Check that the CD is protected by copyright. | |
| Poor sound quality | Check that the CD is scratched or dirty. |
| It takes a relatively long time before the music starts playing. | If there are many folder or file levels on the MP3/WMA CD, or if it is a multi session disc, some time may be required before the music starts playing. |
| The songs do not play back in the desired order. | The playback order is the order in which the files were written by the software, so the files might not play in the desired order. |
Noise resulting from variations in field strength, such as fading noise and multi-path noise, or external noise from trains and other sources, is not a malfunction.
NOTE:
- Fading noise: This noise occurs because of variations in the field strength in a narrow range due to mountains or buildings blocking the signal.
- Multi-path noise: This noise results from a time difference between the broadcast waves directly from the station arriving at the antenna and the waves reflected by mountains or buildings.
