Trouble DiagnosisNKS003LC

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 malfunction-
ing. 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.

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- 8 4 , "
Unable to Operate System with A/C
and AV Switch" (Without navigation system), or AV- 1 3 9 , "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.
NOTE:
Noise resulting from variations in field strength, such as fading noise and multi-path noise, or external noise
from trains and other sources. It is not a malfunction.

Fading noise: This noise occurs because of variations in the field strength in a narrow range due to moun-
tains 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.

Locking CD Auto-Changer MechanismNKS003B1
CAUTION:

Prior to removing a malfunctioning CD auto-changer unit that will be shipped for repair, the
changer mechanism MUST BE LOCKED to prevent the mechanism from being damaged during
shipping.

If a CD is jammed or unable to be removed from the unit, do NOT lock the changer mechanism. If
the unit is to be shipped for repair, carefully package the unit to prevent vibration and shock.
DAMPER LOCK PROCEDURE
1. Eject and remove any CDs from the audio unit.
2. Turn ignition switch OFF. Wait until audio unit display is off and mechanism stops moving (mechanism sound stops).
3. Press any one of the disc selection buttons once. When a display shows on the audio unit, press the same disc selection button again within 5 seconds.

The changer mechanism will lock itself within 10 seconds.
4. After mechanism stops moving (mechanism sound stops), open the driver and passenger window, and then disconnect negative battery cable.
NOTE:
After installing a new or remanufactured audio unit, switching the audio unit ON will automatically unlock the
mechanism. A special unlocking procedure is not required.

NAVIGATION SYSTEM
Revision: 2006 December 2006 FX35/FX45
NAVIGATION SYSTEM
Location Detection Principle
The navigation system periodically calculates the vehicle's current
position according to the following three signals:

Travel distance of the vehicle as determined by the vehicle
speed sensor

Turning angle of the vehicle as determined by the gyroscope
(angular velocity sensor)

Direction of vehicle travel as 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 read from the DVD-ROM,
which is stored in the DVD-ROM drive (map-matching), and indi-
cated on the screen as a current-location mark. More accurate data is judged and used by comparing vehicle
position detection results found by the GPS with the result by map-matching.
The current vehicle position will be calculated by detecting the dis-
tance the vehicle moved from the previous calculation point and its
direction.

Travel distance
Travel distance calculations are based on the vehicle speed
sensor input signal. Therefore, the calculation may become
incorrect as the tires wear down. To prevent this, an automatic
distance correction function has been adopted.

Travel direction
Change in the travel direction of the vehicle is calculated by a
gyroscope (angular velocity sensor) and a GPS antenna (GPS
information). They have both advantages and disadvantages.
More accurate traveling direction is selected because priorities are set for the signals from these two
devices according to the situation.
SKIB1058E
SEL684V
Type Advantage Disadvantage
Gyroscope (angular velocity sen-
sor) 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 vehi-
cle speed is low.
