STARTING THE SELF-DIAGNOSIS MODE
1. Turn ignition switch from OFF to ACC.
2. Within 10 seconds press and hold the switches “1” and “6” simultaneously for 3 seconds.
DIAGNOSIS FUNCTION
The following are checked: All the indicators (LED) in the A/C and AV switch.
Continuity of the switches by sounding the buzze r when the A/C and AV switch and audio steering wheel
switch is pressed.
Continuity of harness between A/C and AV switch and audio steering switch.
NOTE:
Rear window defogger switch operation is not checked. (No beep sound even under normal status)
EXITING THE SELF-DIAGNOSIS MODE
Turn ignition switch OFF.
Trouble DiagnosisINFOID:0000000001328684
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.
Make sure that other operation except audio system can be performed with A/C and AV switch. If these
operations are inoperative with A/C and AV switch, refer to AV-79, "
Unable to Operate System with A/C and
AV Switch" (Without navigation system), or AV-127, "Unable to Operate System with A/C and AV Switch"
(With navigation system).
Refer to "SERVICE BULLETIN ITB04-055" for the diagnosis of satellite radio.

In map-matching, alternative routes are prepared and prioritized in addition to the road judged currently driven. Due to the distance
and/or direction error, the incorrect road may be prioritized and
current-location mark may be repositioned to the wrong road.
When two roads are running in parallel, they are judged to the
same priority. Therefore, the current-location mark may appear on
either of them alternately, depending on maneuvering of the steer-
ing wheel and configuration 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 DVD-ROM, or
when road pattern stored in the map data and the actual road pat-
tern are different due to repair.
When driving on a road not present in the map, the map-matching
function may find another road and position the current-location
mark on it. Then, when the correc t road is detected, the current-
location mark may change to it.
Effective range for comparing the vehicle position and travel direc-
tion calculated by the distance and direction with the road data
read from the DVD-ROM is limited. Therefore, when there is an
excessive gap between current vehicle position and the position on
the map, correction by map-matching is not possible.
GPS (Global Positioning System)
GPS (Global Positioning System) was developed for and is con-
trolled by the US Department of Defense. The system utilizes GPS
satellites (NAVSTAR), sending out radio waves while flying on an
orbit around the earth at an altitude of approximately 21,000 km
(13,100 miles).
The GPS receiver calculates the vehicle's position in three dimen-
sions (latitude/longitude/altitude) ac cording to the time lag of the
radio waves received from four or more GPS satellites (three-dimen-
sional positioning). If radio waves were received only from three
GPS satellites, the GPS receiver ca lculates the vehicle's position in
two dimensions (latitude/longitude) , and utilize the altitude data cal-
culated previously with radio waves from four or more GPS satellites
(two-dimensional positioning).
Position correction by GPS is not available while the vehicle is stopped.
Accuracy of GPS will deteriorate under the following conditions:
In two-dimensional positioning, GPS accuracy will deter iorate when altitude of the vehicle position changes.
The accuracy can be even lower depending on the arrangement of the GPS satellites utilized for the posi-
tioning.
Position detection is not possible when vehicle is in an area where radio waves from the GPS satellite do not
reach, such as in a tunnel, parking lot in a building, and under an elevated highway. Radio waves from the
GPS satellites may not be received when so me object is located over the GPS antenna.
NOTE:
Even a high-precision three dimensional positioning, the detection result has an error about 10 m (30ft).
Because the signals of GPS satellite is controlled by the Tracking and Control Center in the United States,
the accuracy may be degraded lower intentionally or the radio waves may stop.

OPERATION PROCEDURE
1. Start the engine.
2. Turn the audio system OFF.
3. While pressing the “4” button, turn the volume control dial clock- wise or counterclockwise for 30 clicks or more. (When the self-
diagnosis mode is started, a short beep will be heard.)
Shifting from current screen to previous screen is performed
by pressing “BACK” button.

Self Diagnosis (DCU) Display control unit diagnosis
Analyzes connection between the display control unit and each unit, and
operation of each unit.
Self Diagnosis (NAVI) NAVI control unit diagnosis (DVD-ROM drive will not be diagnosed when
no DVD-ROM is in it.).
Analyzes connection between the NAVI control unit and the GPS anten-

Color tone and shading of the display control unit-generated image can be
checked by the display of a color bar and a gray scale.

for Vehicle Speed, IGN, Reverse and Light.
Auto Climate Control Refer to AT C - 4 3 , "

Adjustment
This mode is used to correct difference between actual turning angle of a
vehicle and turning angle of the vehicle mark on the display.
Speed
Calibration Under ordinary conditions, the navigation system distance measuring func-
tion will automatically compensate for minute decreases in wheel and tire
diameter caused by tire wear or low-pressure. Speed Calibration can im-
mediately restore system accuracy in cases such as when distance calibra-
tion is needed because of the use of tire chains.
Error History Malfunctions that occurred in the past are displayed, along with the number
of times each has occurred. Time and location when/where the errors oc-
curred are also displayed.
