STEERING SWITCH SYMPTOM CHART
- 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. (6CD models) 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.
| 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. (6CD models) | |
| Files with extensions other than ".MP3", ".WMA", ".mp3", or ".wma" cannot be played. (6CD models) | |
| 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. (6CD models) |
| 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. |
SYMPTOM CHART
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.
FOR USA AND CANADA : Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT PRE-TENSIONER"
The Supplemental Restraint System such as "AIR BAG" and "SEAT BELT PRE-TENSIONER", used along with a front seat belt, helps to reduce the risk or severity of injury to the driver and front passenger for certain types of collision. This system includes seat belt switch inputs and dual stage front air bag modules. The SRS system uses the seat belt switches to determine the front air bag deployment, and may only deploy one front air bag, depending on the severity of a collision and whether the front occupants are belted or unbelted.
Information necessary to service the system safely is included in the " SRS AIRBAG " and " SEAT BELTS ".
| WARNING | To avoid rendering the SRS inoperative, which could increase the risk of personal injury or death in the event of a collision which would result in air bag inflation, all maintenance must be performed by an authorized NISSAN/INFINITI dealer. Improper maintenance, including incorrect removal and installation of the SRS, can lead to personal injury caused by unintentional activation of the system. For removal of Spiral Cable and Air Bag Module, see the " SRS AIRBAG ". Do not use electrical test equipment on any circuit related to the SRS unless instructed to in this information. SRS wiring harnesses can be identified by yellow and/or orange harnesses or harness connectors. |

- Check that the cellular phone is corresponding type (Bluetooth® enabled) when the hands-free related malfunction vehicle is in service before performing a diagnosis.
- There is a case that malfunction occurs due to the version change of the phone type, etc. even though it is a corresponding type. Therefore, confirm it by changing the cellular phone to another corresponding type phone, and check that it operates normally. It is necessary to distinguish whether the cause is the vehicle or cellular phone. Check to ensure the customer's phone is supported by checking the phone compatibility for the hands-free system.
Simple check for Bluetooth® communication
If cellular phone and TEL adapter unit cannot be connected with Bluetooth® communication, following procedure allows the technician to judge which device has malfunction.
- Turn on a cellular phone, not connecting Bluetooth® communication.
- Start CONSULT-III, then start Windows®.
- Set CONSULT-III near a cellular phone.
- When operated Bluetooth® registration by cellular phone, check if CONSULT-III* would be displayed on the device name. (If other Bluetooth® device is located near cellular phone, a name of the device would be displayed also.) NOTE: *:Displayed device name is "NISSAN-********".
Scheme 66
- If no device name is displayed, cellular phone is malfunction. Repair the cellular phone first, then perform diagnosis.
- If CONSULT-III is displayed on device name, cellular phone is normal. Perform diagnosis as per the following table.
