3. Check continuity between around view monitor c ontrol unit harness connector and door mirror (passenger
side) harness connector.
4. Check continuity between around view m onitor control unit harness connector and ground.
Is inspection result normal?
YES >> GO TO 2.
NO >> Repair harness or connector.
2.CHECK COMMUNICATION SIGNAL
1. Connect around view monitor control unit connector and door mirror (passenger side) connector.
2. Turn ignition switch ON.
3. Check signal between around view monitor control unit harness connector and ground.
Is inspection result normal?
YES >> Replace around view monitor control unit. Refer to AV-233, "Removal and Installation".
NO >> Replace side camera RH. Refer to AV-236, "
Removal and Installation".

< SYMPTOM DIAGNOSIS >
NORMAL OPERATING CONDITION
RELATED TO AUDIO
 The majority of the audio malfunctions are the result of outside causes (bad CD, electromagnetic interfer-
ence, 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 oper-
ation of each piece of electrical equipment, and then determine the cause.
NOTE:
 CD-R is not guaranteed to play because they can c ontain 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.
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 bl ocking
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 DVD
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.
Symptom Solution
Symptom Cause and Counter measure
Cannot play 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 applica-
tions.
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 Check if 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/AAC/M4A CD, or if it is a multisession disc,
some time may be required before the music starts playing.
Music cuts off or skips 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 with high bit rate files Skipping may occur with large quantities if data such as for high bit rate data.
Move immediately to the next song
when playing 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 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.

NORMAL OPERATING CONDITION
RELATED TO ROUTE CALCULATION AND VISUAL GUIDANCE
The vehicle icon is not displayed in
the correct position.The vehicle was transported after the ignition
switch was pressed off, for example, by a ferry
or car transporter.
Drive the vehicle for a while on a road where
GPS signals can be received.
The position and direction of the vehicle icon
may be incorrect depending on the driving en-
vironments and the levels of positioning accu-
racy of the navigation system. This is not a malfunction. Drive the vehicle for
a while to automatically correct the position
and direction of the vehicle icon.
When the vehicle is traveling on a
new road, the vehicle icon is located
on another road nearby. Because the new road is not stored in the map
data, the system automatically places the vehi-
cle icon on the nearest road available.
Updated road information will be included in
the next version of the map data.
The screen does not switch to the
night screen even after turning on
the headlights. The daytime screen was set the last time the
headlights were turned on.
Set the screen to the night screen mode using
when you turn on the headlights.
The map does not scroll even when
the vehicle is moving. The current location map screen is not dis-
played.
Press “MAP”.
The vehicle icon is not displayed. The current location map screen is not dis-
played.
Press “MAP”.
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. Drive the vehicle for a while [at approximately
30 km/h (19 MPH) for about 30 minutes] to
automatically correct the vehicle icon posi-
tion.
If this does not correct the vehicle icon posi-
tion, contact an INFINITI dealer.
The map data has a mistake or is incomplete
(the vehicle icon position is always misaligned
in the same area). Updated road information will be included in
the next version of the map data.
Symptom Possible cause Possible solution
Symptom Possible cause Possible solution
Waypoints are not included in
the auto reroute calculation. Waypoints that you have already passed are not included in
the auto reroute calculation. If you want to go to that waypoint
again, you need to edit the route.
Route information is not dis-
played. Route calculation has not yet been performed.
Set the destination and perform route
calculation.
You are not driving on the suggested route. Drive on the suggested route.
Route guidance is set to off. Turn on route guidance.
Route information is not provided for certain types of roads
(roads displayed in gray). This is not a malfunction.
The auto reroute calculation (or
detour calculation) suggests
the same route as the one pre-
viously suggested. Route calculations took priority conditions into consider-
ation, but the same route was calculated.
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 calcu-
lations multiple times as necessary.
The suggested route is not dis-
played. Roads near the destination cannot be calculated.
Reset the destination to a main or or-
dinary road, and recalculate the route.
The starting point and destination are too close. Set a more distant destination.
The starting point and destination are too far away. Divide your trip by selecting one or two
intermediate destinations, and per-
form route calculations multiple times.
There are time restricted roads (by the day of the week, by
time) near the current vehicle location or destination. Set [Use Time Restricted Roads] to
off.
