Symptom TableINFOID:0000000001728624
RELATED TO AUDIO
RELATED TO HANDS FREE PHONE
 Check that the cellular phone is corresponding type (Bluetooth® enabled) when the hands free related mal-
function 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 customers phone is supported by checking the phone compatibility for
the hands free system.

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 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 incor-
rectly 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.
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 TELEPHONE
Symptoms Cause and Counter measure
Cannot playCheck 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 (CD-
DA 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 multisession 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.
Symptom Possible cause Possible solution
The system does not recognize the
command.
The system recognizes the com-
mand incorrectly.The interior of the vehicle is too noisy.Close the windows or have other occupants
be quiet.
The volume of the voice is too low. Speak louder.
Pronunciation is unclear. Speak clearly.
Voice recognition mode is not yet ready to speak.Push the release “ ” on the steering
switch, and speak a command after the
tone sounds.
5 seconds or more have passed after pushed and
released “ ” on the steering switch.Make sure to speak a command within
5seconds after push and release “ ” on
the steering switch.

 NAVI control unit is connected with display and serial communication, and it sends the required signal of dis-
play and display control and receives the response signal from front display. Also, it is connected with satel-
lite radio by serial communication, and it sends the operating signal and receives the display signal.
NOTE:
NAVI control unit can perform CONSULT-III self-operating function and on board self-diagnosis.
 CONSULT-III self diagnosis: Refer to AV-48, "
CONSULT - III Function (MULTI AV)".
 On board self diagnosis: Refer to AV-39, "
Diagnosis Description".
HANDS-FREE PHONE SYSTEM
 Hands-free communication can be operated by connecting using Bluetooth® with cellular phone.
 Operation is performed by steering switch, and operating condition is indicated on display.
 Guide sound that is heard during operation is input from NAVI control unit to audio unit and is output from
front speaker.
When a call is originated
Spoken voice sound output from the microphone (Mic. Signal) is input to NAVI control unit. NAVI control unit
outputs to cellular phone with Bluetooth
® communication as a TEL voice signal. Voice sound is then heard at
the other party.
When receiving a call
Voice sound is input to own cellular phone from the other party. TEL voice signal is output to front speaker, and
the signal is input to audio unit via NAVI control unit by establishing Bluetooth
® communication from cellular
phone.

Part name Description
NAVI CONTROL UNIT Map data can be read from the Map DVD-ROM by installing Map DVD-ROM.
 It is the master unit of the MULTI AV system, and it is connected to each con-
trol unit by means of communication. It operates each system according to
communication signals from the NAVI control unit.
 The NAVI control unit includes the audio, hands-free phone, navigation, and
vehicle information functions.
 It is connected to ECM and combination meter via CAN communication to ob-
tain necessary information for the vehicle information function.

NAVIGATION SYSTEM
More accurate traveling direction is detected because priorities are set for the signals from these two
devices according to the situation.
Map-Matching
Map-matching compares a current location detected by the method
in the “Location Detection Principle” with a road map data from Map
DVD-ROM stored in DVD-ROM drive.
NOTE:
The road map data is based on data stored in the map DVD-ROM.
The vehicle position may not be corrected under the following circumstances and after driving for a certain
time when GPS information is difficult to receive. In this case, the vehicle mark on the display must be cor-
rected manually.
 In map-matching, alternative routes to reach the destination will be
shown and prioritized, after the road on which the vehicle is cur-
rently driven has been judged and the vehicle mark has been repo-
sitioned.
Alternative routes will be shown in different order of priority, and
the incorrect road can be avoided if there is an error in distance
and/or direction.
They are of the same priority if two roads are running in parallel.
Therefore, the vehicle mark may appear on either of them alter-
nately, depending on maneuvering of the steering wheel and con-
figuration of the road.
 Map-matching does not function correctly when a road on which
the vehicle is driving is new and not recorded in the map DVD-
ROM, or when road pattern stored in the map data and the actual
road pattern are different due to repair.
The map-matching function may find another road and position the
vehicle mark on it when driving on a road not present in the map.
Then, the vehicle mark may change to it when the correct road is
detected.
 Effective range for comparing the vehicle position and travel direc-
tion calculated by the distance and direction with the road data
read from the map DVD-ROM 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)
Type Advantage Disadvantage
Gyroscope
(angular velocity sensor)Can detect the vehicle's turning angle quite
accurately.Direction errors may accumulate when vehicle is
driven for long distances without stopping.
GPS antenna
(GPS information)Can detect the vehicle's travel direction
(North/South/East/West).Correct direction cannot be detected when vehicle
speed is low.
