U1000 CAN COMM CIRCUIT
Description
INFOID:0000000005705430

CAN (Controller Area Network) is a serial communication line for real-time application. It is an on-vehicle multiplex communication line with high data communication speed and excellent error detection ability. Many electronic control units are equipped onto a vehicle, and each control unit shares information and links with other control units during operation (not independently). In CAN communication, control units are connected with 2 communication lines (CAN-H, CAN-L) allowing a high rate of information transmission with less wiring. Each control unit transmits/receives data but selectively reads required data only. CAN Communication Signal Chart. Refer to LAN-27, "CAN Communication Signal Chart".

< SYMPTOM DIAGNOSIS > [BASE AUDIO WITHOUT REAR VIEW CAMERA]

NORMAL OPERATING CONDITION

Description
BASIC OPERATIONS
Symptom Possible cause The brightness is at the lowest setting. No image is displayed. The system in the video mode. The display is turned off. The screen is too dim. The movement is slow. Some pixels in the display are darker or brighter than others. Some menu items cannot be selected. The temperature in the interior of the vehicle is low. This condition is an inherent characteristic of liquid crystal displays. Some menu items become unavailable while the vehicle is driven. Possible solution Adjust the brightness of the display. Press <DISC> to change the mode. Press <Day/Night> to turn on the display. Wait until the interior of the vehicle has warmed up. This is not a malfunction. Park the vehicle in a safe location, and then operate the multi AV system.
INFOID:0000000005705492

RELATED TO AUDIO
The majority of the audio malfunctions are the result of outside causes (bad CD/cassette, 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 if noise is caused and/or changed by engine speed, ignition switch turned to each position, and operation of each piece of electrical equipment, and 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 if the CDs carry the Compact Disk Logo. If not, the disk is not mastered to the red book Compact Disk Standard and may not play.
Symptom Cause and Counter measure Check if the CD was inserted correctly. Check if the CD is scratched or dirty. Check if there is condensation inside the player, and if there is, wait until the condensation is gone (about 1 hour) before using the player. If there is a temperature increase error, the player will play correctly after it returns to the normal temperature. Cannot play If there is a mixture of music CD files (CD-DA data) and MP3/WMA files on a CD, only the music CD files (CD-DA data) will be played. Files with extensions other than .MP3, .WMA, .mp3, or .wma cannot be played. In addition, the character codes and number of characters for folder names and file names should be in compliance with the specifications. Check if the disk or the file is generated in an irregular format, This may occur depending on the variation or the setting of MP3/WMA writing applications or other text editing applications. Check if the finalization process, such as session close and disk close, is done for the disk. Check if the CD is protected by copyright. Poor sound quality It takes a relatively long time before the music starts playing. Music cuts off or skips Skipping with high bit rate files Check if the CD is scratched or dirty. If there are many folder or file levels on the MP3/WMA CD, or if it is a multisession disk, some time may be required before the music starts playing. The writing software and hardware combination might not match, or the writing speed, writing depth, writing width might not match the specifications. Try using the slowest writing speed. Skipping may occur with large quantities if data such as for high bit rate data.

NORMAL OPERATING CONDITION

< SYMPTOM DIAGNOSIS >
Symptom Move immediately to the next song when playing The songs do not play back in the desired order.

[BASE AUDIO WITHOUT REAR VIEW CAMERA]

Cause and Counter measure When a non-MP3/WMA file has been given an extension of .MP3, .WMA, .mp3, or .wma, or when play is prohibited by copyright protection, the player will skip to the next song. 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.

< PRECAUTION > [BASE AUDIO WITHOUT REAR VIEW CAMERA]

PRECAUTION
PRECAUTIONS
Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT PRE-TENSIONER"
INFOID:0000000005768859

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 AIR BAG and SEAT BELT of this Service Manual. 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 AIR BAG. Do not use electrical test equipment on any circuit related to the SRS unless instructed to in this Service Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or harness connectors.

PRECAUTIONS WHEN USING POWER TOOLS (AIR OR ELECTRIC) AND HAMMERS

WARNING: When working near the Air Bag Diagnosis Sensor Unit or other Air Bag System sensors with the ignition ON or engine running, DO NOT use air or electric power tools or strike near the sensor(s) with a hammer. Heavy vibration could activate the sensor(s) and deploy the air bag(s), possibly causing serious injury. When using air or electric power tools or hammers, always switch the ignition OFF, disconnect the battery, and wait at least 3 minutes before performing any service.

Precaution for Battery Service

INFOID:0000000005905009

Before disconnecting the battery, lower both the driver and passenger windows. This will prevent any interference between the window edge and the vehicle when the door is opened/closed. During normal operation, the window slightly raises and lowers automatically to prevent any window to vehicle interference. The automatic window function will not work with the battery disconnected.

Precaution for Trouble Diagnosis

AV COMMUNICATION SYSTEM

INFOID:0000000005705494

Do not apply voltage of 7.0 V or higher to the measurement terminals. Use the tester with its open terminal voltage being 7.0 V or less. Be sure to turn ignition switch OFF and disconnect the battery cable from the negative terminal before checking the circuit.

PRECAUTION
PRECAUTIONS
Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT PRE-TENSIONER"
INFOID:0000000005768860

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 AIR BAG and SEAT BELT of this Service Manual. 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 AIR BAG. Do not use electrical test equipment on any circuit related to the SRS unless instructed to in this Service Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or harness connectors.

PRECAUTIONS WHEN USING POWER TOOLS (AIR OR ELECTRIC) AND HAMMERS

WARNING: When working near the Air Bag Diagnosis Sensor Unit or other Air Bag System sensors with the ignition ON or engine running, DO NOT use air or electric power tools or strike near the sensor(s) with a hammer. Heavy vibration could activate the sensor(s) and deploy the air bag(s), possibly causing serious injury. When using air or electric power tools or hammers, always switch the ignition OFF, disconnect the battery, and wait at least 3 minutes before performing any service.

Precaution for Battery Service

INFOID:0000000005905012

Before disconnecting the battery, lower both the driver and passenger windows. This will prevent any interference between the window edge and the vehicle when the door is opened/closed. During normal operation, the window slightly raises and lowers automatically to prevent any window to vehicle interference. The automatic window function will not work with the battery disconnected.

Precaution for Trouble Diagnosis

AV COMMUNICATION SYSTEM

INFOID:0000000005689077

Do not apply voltage of 7.0 V or higher to the measurement terminals. Use the tester with its open terminal voltage being 7.0 V or less. Be sure to turn ignition switch OFF and disconnect the battery cable from the negative terminal before checking the circuit.

This condition is an inherent characteristic of liquid crystal displays. Some menu items become unavailable while the vehicle is driven. Possible solution Adjust the brightness of the display. Press DISC-AUX to change the mode. Press OFF to turn on the display.

Wait until the interior of the vehicle has warmed up. This is not a malfunction. Park the vehicle in a safe location, and then operate the multi AV system.

RELATED TO VOICE RECOGNITION

Related to Telephone The system should respond correctly to all voice commands without difficulty. If problems are encountered, try the following solutions. Where the solutions are listed by number, try each solution in turn, starting with number 1, until the problem is resolved.
Symptom 1. Ensure that the command is valid. 2. Ensure that the command is spoken after the tone. 3. Speak clearly without pausing between words and at level appropriate to the ambient noise level in the vehicle. System fails to interpret the command correctly. 4. Ensure that the ambient noise level is not excessive (for example, windows open or defroster on). NOTE: If it is too noisy to use the phone, it is likely that the voice commands will not be recognized. 5. If more than one command was said at a time, try saying the commands separately. 6. If the system consistently fails to recognize commands, the voice training procedure should be carried out to improve the recognition response for the speaker. See Speaker adaptation (SA) mode earlier in this section. Refer to OWNERS MANUAL. The system consistently selects the wrong voicetag 1. Ensure that the phone book entry name requested matches what was originally stored. This can be confirmed by using the List Names command. 2. Replace one of the names being confused with a new name. Solution

RELATED TO AUDIO
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 if noise is caused and/or changed by engine speed, ignition switch turned to each position, and operation of each piece of electrical equipment, and then determine the cause. NOTE: CD-R is not guaranteed to play because they can contain compressed audio (MP3, WMA, AAC, M4A) or could be incorrectly mastered by the customer on a computer. Check if 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.

NORMAL OPERATING CONDITION

< SYMPTOM DIAGNOSIS >
Symptom

[BASE AUDIO WITH REAR VIEW CAMERA]

Cause and Counter measure Check if the CD was inserted correctly. Check if the CD is scratched or dirty. Check if there is condensation inside the player, and if there is, wait until the condensation is gone (about 1 hour) before using the player. If there is a temperature increase error, the player will play correctly after it returns to the normal temperature. If there is a mixture of music CD files (CD-DA data) and MP3/WMA/AAC/M4A files on a CD, only the music CD files (CD-DA data) will be played. Files with extensions other than .MP3, .WMA, .AAC, .M4A, .mp3, .wma, .aac or .m4a cannot be played. In addition, the character codes and number of characters for folder names and file names should be in compliance with the specifications. Check if the disc or the file is generated in an irregular format, This may occur depending on the variation or the setting of MP3/WMA/AAC/M4A writing applications or other text editing applications. Check if the finalization process, such as session close and disc close, is done for the disc. Check if the CD is protected by copyright. Discs recorded in live file system format are not supported. (For Microsoft Windows Vista, check the settings.)

Cannot play

Poor sound quality It takes a relatively long time before the music starts playing. Music cuts off or skips Skipping with high bit rate files Move immediately to the next song when playing The songs do not play back in the desired order.

Check if the CD is scratched or dirty. If there are many folder or file levels on the MP3/WMA/AAC/M4A CD, or if it is a multisession disc, some time may be required before the music starts playing. The writing software and hardware combination might not match, or the writing speed, writing depth, writing width might not match the specifications. Try using the slowest writing speed. Skipping may occur with large quantities if data such as for high bit rate data. When a non-MP3/WMA/AAC/M4A file has been given an extension of .MP3, .WMA, .AAC, .M4A, .mp3, .wma, .aac or .m4a or when play is prohibited by copyright protection, the player will skip to the next song. 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.

PRECAUTION
PRECAUTIONS
Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT PRE-TENSIONER"

INFOID:0000000005768861

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 AIR BAG and SEAT BELT of this Service Manual. 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 AIR BAG. Do not use electrical test equipment on any circuit related to the SRS unless instructed to in this Service Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or harness connectors.

PRECAUTIONS WHEN USING POWER TOOLS (AIR OR ELECTRIC) AND HAMMERS

WARNING: When working near the Air Bag Diagnosis Sensor Unit or other Air Bag System sensors with the ignition ON or engine running, DO NOT use air or electric power tools or strike near the sensor(s) with a hammer. Heavy vibration could activate the sensor(s) and deploy the air bag(s), possibly causing serious injury. When using air or electric power tools or hammers, always switch the ignition OFF, disconnect the battery, and wait at least 3 minutes before performing any service.

Precaution for Battery Service

INFOID:0000000005905056

Before disconnecting the battery, lower both the driver and passenger windows. This will prevent any interference between the window edge and the vehicle when the door is opened/closed. During normal operation, the window slightly raises and lowers automatically to prevent any window to vehicle interference. The automatic window function will not work with the battery disconnected.

Precaution for Trouble Diagnosis

AV COMMUNICATION SYSTEM

INFOID:0000000005688816

Do not apply voltage of 7.0 V or higher to the measurement terminals. Use the tester with its open terminal voltage being 7.0 V or less. AV Be sure to turn ignition switch OFF and disconnect the battery cable from the negative terminal before checking the circuit.

U1000 CAN COMM CIRCUIT
Description
INFOID:0000000005853009

CAN (Controller Area Network) is a serial communication line for real-time application. It is an on-vehicle multiplex communication line with high data communication speed and excellent error detection ability. Many electronic control units are equipped onto a vehicle, and each control unit shares information and links with other control units during operation (not independently). In CAN communication, control units are connected with 2 communication lines (CAN-H, CAN-L) allowing a high rate of information transmission with less wiring. Each control unit transmits/receives data but selectively reads required data only. CAN Communication Signal Chart. Refer to LAN-27, "CAN Communication Signal Chart".

Symptom Possible cause The brightness is at the lowest setting. No image is displayed. The systems in the video mode. The display is turned off. The screen is too dim. The movement is slow. Some pixels in the display are darker or brighter than others. Some menu items cannot be selected. The temperature in the interior of the vehicle is low. This condition is an inherent characteristic of liquid crystal displays. Some menu items become unavailable while the vehicle is driven. Possible solution Adjust the brightness of the display. Press DISC-AUX to change the mode. Press OFF to turn on the display.
INFOID:0000000005688897

Wait until the interior of the vehicle has warmed up. This is not a malfunction. Park the vehicle in a safe location, and then operate the multi AV system.

RELATED TO VOICE RECOGNITION

Related to Telephone The system should respond correctly to all voice commands without difficulty. If problems are encountered, try the following solutions. Where the solutions are listed by number, try each solution in turn, starting with number 1, until the problem is resolved.
Symptom 1. Ensure that the command is valid. 2. Ensure that the command is spoken after the tone. 3. Speak clearly without pausing between words and at level appropriate to the ambient noise level in the vehicle. System fails to interpret the command correctly. 4. Ensure that the ambient noise level is not excessive (for example, windows open or defroster on). NOTE: If it is too noisy to use the phone, it is likely that the voice commands will not be recognized. 5. If more than one command was said at a time, try saying the commands separately. 6. If the system consistently fails to recognize commands, the voice training procedure should be carried out to improve the recognition response for the speaker. See Speaker adaptation (SA) mode earlier in this section. Refer to OWNERS MANUAL. The system consistently selects the wrong voicetag 1. Ensure that the phone book entry name requested matches what was originally stored. This can be confirmed by using the List Names command. 2. Replace one of the names being confused with a new name. Solution

RELATED TO AUDIO
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 if noise is caused and/or changed by engine speed, ignition switch turned to each position, and operation of each piece of electrical equipment, and then determine the cause. NOTE: CD-R is not guaranteed to play because they can contain compressed audio (MP3, WMA, AAC, M4A) or could be incorrectly mastered by the customer on a computer. Check if 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.

NORMAL OPERATING CONDITION

< SYMPTOM DIAGNOSIS >
Symptom

[BOSE AUDIO WITHOUT NAVIGATION]

Cause and Counter measure Check if the CD was inserted correctly. Check if the CD is scratched or dirty. Check if there is condensation inside the player, and if there is, wait until the condensation is gone (about 1 hour) before using the player. If there is a temperature increase error, the player will play correctly after it returns to the normal temperature. If there is a mixture of music CD files (CD-DA data) and MP3/WMA/AAC/M4A files on a CD, only the music CD files (CD-DA data) will be played. Files with extensions other than .MP3, .WMA, .AAC, .M4A, .mp3, .wma, .aac or .m4a cannot be played. In addition, the character codes and number of characters for folder names and file names should be in compliance with the specifications. Check if the disc or the file is generated in an irregular format, This may occur depending on the variation or the setting of MP3/WMA/AAC/M4A writing applications or other text editing applications. Check if the finalization process, such as session close and disc close, is done for the disc. Check if the CD is protected by copyright. Discs recorded in live file system format are not supported. (For Microsoft Windows Vista, check the settings.)

Cannot play

Poor sound quality It takes a relatively long time before the music starts playing. Music cuts off or skips Skipping with high bit rate files Move immediately to the next song when playing The songs do not play back in the desired order.

Check if the CD is scratched or dirty. If there are many folder or file levels on the MP3/WMA/AAC/M4A CD, or if it is a multisession disc, some time may be required before the music starts playing. The writing software and hardware combination might not match, or the writing speed, writing depth, writing width might not match the specifications. Try using the slowest writing speed. Skipping may occur with large quantities if data such as for high bit rate data. When a non-MP3/WMA/AAC/M4A file has been given an extension of .MP3, .WMA, .AAC, .M4A, .mp3, .wma, .aac or .m4a or when play is prohibited by copyright protection, the player will skip to the next song. 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.

PRECAUTION
PRECAUTIONS
Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT PRE-TENSIONER"
INFOID:0000000005768862

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 AIR BAG and SEAT BELT of this Service Manual. 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 AIR BAG. Do not use electrical test equipment on any circuit related to the SRS unless instructed to in this Service Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or harness connectors.

PRECAUTIONS WHEN USING POWER TOOLS (AIR OR ELECTRIC) AND HAMMERS

WARNING: When working near the Air Bag Diagnosis Sensor Unit or other Air Bag System sensors with the ignition ON or engine running, DO NOT use air or electric power tools or strike near the sensor(s) with a hammer. Heavy vibration could activate the sensor(s) and deploy the air bag(s), possibly causing serious injury. When using air or electric power tools or hammers, always switch the ignition OFF, disconnect the battery, and wait at least 3 minutes before performing any service.

Precaution for Battery Service

INFOID:0000000005905057

Before disconnecting the battery, lower both the driver and passenger windows. This will prevent any interference between the window edge and the vehicle when the door is opened/closed. During normal operation, the window slightly raises and lowers automatically to prevent any window to vehicle interference. The automatic window function will not work with the battery disconnected.

Precaution for Trouble Diagnosis

AV COMMUNICATION SYSTEM

INFOID:0000000005685294

Do not apply voltage of 7.0 V or higher to the measurement terminals. Use the tester with its open terminal voltage being 7.0 V or less. Be sure to turn ignition switch OFF and disconnect the battery cable from the negative terminal before checking the circuit.

COMMUNICATION SIGNAL

Revision: 2009 November

AV-360

2010 G37 Coupe

SYSTEM
[BOSE AUDIO WITH NAVIGATION] < SYSTEM DESCRIPTION > AV control unit function by transmitting/receiving data one by one with each unit (slave unit) that configures them completely as a master unit by connecting between units that configure MULTI AV system with two AV communication lines (H, L). Two AV communication lines (H, L) adopt a twisted pair line that is resistant to noise. AV control unit is connected by CAN communication, and it receives data signal from ECM, unified meter and A/C amp. It computes and displays fuel economy information value with the obtained information. AV control unit is connected with display and serial communication, and it transmits the required signal of display and display control and receives the response signal from display.

NAVIGATION SYSTEM FUNCTION

Description The AV control unit controls navigation function while GPS tuner has built-in map data, GYRO (angle speed sensor), on the HDD (Hard Disk Drive). The AV control unit inputs operation signal with communication signal, through display (touch panel) and multifunction switch and steering switch. Guide sound is output to front speaker through BOSE amp. from AV control unit when operating navigation system. A vehicle position is calculated with the GYRO (angle speed sensor), vehicle sensor, signal from GPS satellite and map data stored on HDD (Hard Disk Drive), and transmits the map image signal (RGB image, RGB area, RGB image synchronizing) to the display. Position Detection Principle The navigation system periodically calculates the current vehicle position according to the following three types of signals. Travel distance of the vehicle as determined by the vehicle speed sensor Vehicle turning angle determined by the gyroscope (angular speed sensor) The travel direction of the vehicle determined by the GPS antenna (GPS information) The current position of the vehicle is then identified by comparing the calculated vehicle position with map data, which is stored in the HDD (Hard Disk Drive) (map-matching), and indicated on the screen with a current location mark. More accurate data is used by comparing position detection results from GPS to the map-matching. The current position is calculated by detecting the travel distance from the previous calculation point, and its direction change. Travel distance The travel distance is generated from the vehicle speed sensor input signal. The automatic distance correction function is adopted for preventing a miss-detection of the travel distance because of tire wear etc. Travel direction The gyroscope (angular velocity sensor) and GPS antenna (GPS information) generate the change of the travel direction. Both have advantages and disadvantages as per the following descriptions.

JSNIA0177GB

SEL684V

AV

Type Gyroscope (angular velocity sensor) GPS antenna (GPS information)

Advantage The turning angle is precisely detected. The travel direction (North/South/East/West) is detected.

Disadvantage Errors are accumulated when driving a long distance without stopping. The travel direction is not precisely detected when driving slowly.

Input signals are prioritized in each situation. However, this order of priority may change in accordance with more detailed travel conditions so that the travel direction is detected more accurately.
Map-matching

Revision: 2009 November

AV-361

2010 G37 Coupe

SYSTEM
[BOSE AUDIO WITH NAVIGATION] < SYSTEM DESCRIPTION > Map-matching repositions the vehicle on the road map when a new location is judged to be more accurate. This is done by comparing the current vehicle position (calculated by the normal position detection method) from the map data stored in the HDD (Hard Disk Drive).

SEL685V

There is a possibility that the vehicle position may not be corrected in the following case, and when vehicle is driven over a certain distance or time in which GPS information is hard to receive. Correct manually the current location mark on the screen. In map-matching, several alternative routes are prepared and prioritized in addition to the road judged as currently driving on. Therefore, due to errors in the distance and/or direction, an incorrect road may be prioritized, and the current location mark may be repositioned to the incorrect road. If two roads are running in parallel, they are of the same priority. Therefore, the current location mark may appear on either of them alternately, depending on maneuvering of the steering wheel and configuration of the road, etc.
SEL686V

Map-matching does not function correctly when road on which the vehicle is driving is new, etc. and not recorded in the map data. Also, map-matching does not function correctly when road pattern stored in the map data and the actual road pattern are different due to repair, etc. Therefore, the map-matching function judges other road as a currently driving road if the road is not in the map, and displays the current location mark on it. Later, the current location mark may be repositioned to the road if the correct road is detected. Effective range for comparing the vehicle position and travel direction calculated by the distance and direction with the road data is limited. Therefore, correction by map-matching is not possible when there is an excessive gap between current vehicle position and the position on the map.
GPS (Global Positioning System) GPS (Global Positioning System) is developed for and is controlled by the US Department of Defense. The system utilizes GPS satellites (NAVSTAR), transmitting out radio waves while flying on an orbit around the earth at an altitude of approximately 21,000 km (13,049 mile). The receiver calculates the travel position in three dimensions (latitude/longitude/altitude) according to the time lag of the radio waves that four or more GPS satellites transmit (three-dimensional positioning). The GPS receiver calculates the travel position in two dimensions (latitude/longitude) with the previous altitude data if the GPS receiver receives only three radio waves (two-dimensional positioning). GPS position correction is not performed while stopping the vehicle.

JSNIA0180GB

SEL526V

Accuracy of the GPS will deteriorate under the following conditions: In two-dimensional positioning, GPS accuracy will deteriorate when altitude of the vehicle position changes. The position of GPS satellite affects GPS detection precision. The position detection may not be precisely performed.
Revision: 2009 November

AV-362

2010 G37 Coupe

SYSTEM
[BOSE AUDIO WITH NAVIGATION] < SYSTEM DESCRIPTION > The position detection is not performed if GPS receiver does not receive radio waves from GPS satellites. (Inside a tunnel, parking in a building, under an elevated highway etc.) GPS receiver may not receive radio waves from GPS satellites if any object is placed on the GPS antenna. NOTE: The detection result has an error of approximately 10 m (32.81 ft) even with a high-precision three dimensional positioning. There may be cases when the accuracy is lowered and radio waves are stopped intentionally because the GPS satellite signal is controlled by the US trace control center.

Description
INFOID:0000000005851502

CAN (Controller Area Network) is a serial communication line for real-time application. It is an on-vehicle multiplex communication line with high data communication speed and excellent error detection ability. Many electronic control units are equipped onto a vehicle, and each control unit shares information and links with other control units during operation (not independently). In CAN communication, control units are connected with 2 communication lines (CAN-H, CAN-L) allowing a high rate of information transmission with less wiring. Each control unit transmits/receives data but selectively reads required data only. CAN Communication Signal Chart. Refer to LAN-27, "CAN Communication Signal Chart".

Solution

RELATED TO AUDIO
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 if noise is caused and/or changed by engine speed, ignition switch turned to each position, and operation of each piece of electrical equipment, and then determine the cause. NOTE: CD-R is not guaranteed to play because they can contain compressed audio (MP3, WMA, AAC, M4A) or could be incorrectly mastered by the customer on a computer. Check if 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.

Symptom

[BOSE AUDIO WITH NAVIGATION]

Cause and Counter measure Check if the CD was inserted correctly. Check if the CD is scratched or dirty. Check if there is condensation inside the player, and if there is, wait until the condensation is gone (about 1 hour) before using the player. If there is a temperature increase error, the player will play correctly after it returns to the normal temperature. If there is a mixture of music CD files (CD-DA data) and MP3/WMA/AAC/M4A files on a CD, only the music CD files (CD-DA data) will be played.

Cannot play

Files with extensions other than .MP3, .WMA, AAC, .M4A, .mp3, .wma, .aac or .m4a cannot be played. In addition, the character codes and number of characters for folder names and file names should be in compliance with the specifications. Check if the disc or the file is generated in an irregular format, This may occur depending on the variation or the setting of MP3/WMA/AAC/M4A writing applications or other text editing applications. Check if the finalization process, such as session close and disc close, is done for the disc. Check if the CD is protected by copyright. Disks recorded in live file system format are not supported. (For Microsoft Windows Vista, check the settings.)

Poor sound quality It takes a relatively long time before the music starts playing. Music cuts off or skips Skipping with high bit rate files Move immediately to the next song when playing The songs do not play back in the desired order.

Check if the CD is scratched or dirty. If there are many folder or file levels on the MP3/WMA/AAC/M4A CD, or if it is a multisession disc, some time may be required before the music starts playing. The writing software and hardware combination might not match, or the writing speed, writing depth, writing width might not match the specifications. Try using the slowest writing speed. Skipping may occur with large quantities if data such as for high bit rate data. When a non-MP3/WMA/AAC/M4A file has been given an extension of .MP3, .WMA, AAC, .M4A .mp3, .wma, .aac or .m4a, or when play is prohibited by copyright protection, the player will skip to the next song. 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.

RELATED TO VEHICLE ICON

Symptom Possible cause This is because the quantity of the displayed information is reduced so that the screen does not become too crowded. There is also a chance that names of the roads may be displayed multiple times, and the names appearing on the screen may be different because of a processing procedure. The vehicle was transported after the ignition switch was pressed off, for example, by a ferry or car transporter. The position and direction of the vehicle icon may be incorrect depending on the driving environments and the levels of positioning accuracy of the navigation system. Because the new road is not stored in the map data, the system automatically places the vehicle icon on the nearest road available. Possible solution

Names of roads differ between Plan View and Birdview.

This is not a malfunction.

Drive the vehicle for a while on a road where GPS signals can be received. This is not a malfunction. Drive the vehicle for a while to automatically correct the position and direction of the vehicle icon. Updated road information will be included in the next version of the map data.

The vehicle icon is not displayed in the correct position.

When the vehicle is traveling on a new road, the vehicle icon is located on another road nearby.

NORMAL OPERATING CONDITION

< SYMPTOM DIAGNOSIS >
Symptom The screen does not switch to the night screen even after turning on the headlights. The map does not scroll even when the vehicle is moving. The vehicle icon is not displayed. Possible cause The daytime screen was set the last time the headlights were turned on. The current location map screen is not displayed. The current location map screen is not displayed.

[BOSE AUDIO WITH NAVIGATION]

Possible solution

A
Set the screen to the night screen mode using <Day/Night> when you turn on the headlights. Press MAP. Press MAP. Drive the vehicle for a while [at approximately 30 km/h (19 MPH) for about 30 minutes] to automatically correct the vehicle icon position. If this does not correct the vehicle icon position, contact an INFINITI dealer. Updated road information will be included in the next version of the map data.

The location of the vehicle icon is misaligned from the actual position.

When using tire chains or replacing the tires, speed calculations based on the speed sensor may be incorrect.

The map data has a mistake or is incomplete (the vehicle icon position is always misaligned in the same area).

RELATED TO ROUTE CALCULATION AND VISUAL GUIDANCE

Symptom Waypoints are not included in the auto reroute calculation. Possible cause Waypoints that you have already passed are not included in the auto reroute calculation. Route calculation has not yet been performed. Route information is not displayed. You are not driving on the suggested route. Route guidance is set to off. Route information is not provided for certain types of roads (roads displayed in gray). The auto reroute calculation (or detour calculation) suggests the same route as the one previously suggested. Route calculations took priority conditions into consideration, but the same route was calculated. Possible solution If you want to go to that waypoint again, you need to edit the route. Set the destination and perform route calculation. Drive on the suggested route. Turn on route guidance. This is not a malfunction.

J
This is not a malfunction.

A waypoint cannot be added.

Five waypoints are already set on the route, including ones that you have already passed.

A maximum of 5 waypoints can be set on the route. If you want to go to 6 or more waypoints, perform route calculations multiple times as necessary. Reset the destination to a main or ordinary road, and recalculate the route. Set a more distant destination. Divide your trip by selecting one or two intermediate destinations, and perform route calculations multiple times. Set [Use Time Restricted Roads] to off.

Roads near the destination cannot be calculated. The starting point and destination are too close. The suggested route is not displayed. The starting point and destination are too far away. There are time restricted roads (by the day of the week, by time) near the current vehicle location or destination. The part of the route that you have already passed is deleted. A route is managed by sections between waypoints. If you passed the first waypoint, the section between the starting point and the waypoint is deleted. (It may not be deleted depending on the area.) If there are restrictions (such as one-way streets) on roads close to the starting point or destination, the system may suggest an indirect route. The system may suggest an indirect route because route calculation does not take into consideration some areas such as narrow streets (gray roads.)

AV

O
This is not a malfunction.

Adjust the location of the starting of the starting point or destination. Reset the destination to a main or ordinary road, and recalculate the route.

An indirect route is suggested.

NORMAL OPERATING CONDITION

< SYMPTOM DIAGNOSIS >
Symptom The landmark information does not correspond to the actual information. The suggested route does not exactly connect to the starting point, waypoints, or destination. Possible cause This may be caused by insufficient or incorrect map data.

[BOSE AUDIO WITH NAVIGATION]

Possible solution Updated information will be included in the next version of the data. Set the starting point, waypoints and destination on a main road, and perform route calculation.

There is no data for route calculation closes to these locations.

RELATED TO VOICE GUIDANCE

Symptom Possible cause Voice guidance is only available at certain intersections marked with? In some case, voice guidance is not available even when the vehicle should make a turn. Voice guidance is not available The vehicle has deviated from the suggested route. Voice guide is set to off. Route guidance is set to off. The guidance contact does not correspond to the actual condition. The contact of voice guidance may vary, depending on the types of intersections at which turn are made. Possible solution This is not a malfunction. Go back to the suggested route or request route calculation again Turn on voice guidance. Turn on voice guidance. Follow all traffic rules and regulations.
