Substitute a known-good USB adapter unit
(see page 23-258), then reconnect all of the
connectors and recheck. If the symptom/indication
goes away, replace the original USB adapter unit. If
the symptom/indication is still present, replace the
navigation unit (see page 23-355).
Open in the wire(s) between the navigation
unit and the USB adapter unit. Replace affected
shielded harness. NOTE:
 Check the vehicle battery condition first.
 Check the connectors for poor connections or loose terminals.
1. Turn the ignition switch to ON (II).
2. Do the speaker check mode with the self-diagnostic mode.
Go to step 3.
Go to no sound is heard from speaker(s).
3. Turn the ignition switch to LOCK (0).
4. Connect the client’s USB device to a known-good vehicle that equipped with the USB adapter and
check the USB device operation.
Go to step 5.
USB device is faulty. Also check the USB
cable and USB adapter connector condition.
5. On the client’s vehicle, connect the client’s USB device to the USB adapter.
6. Turn the ignition switch to ON (II), and turn on the audio unit.
7. Check if the USB device can be operated with the audio unit (Folders or Files UP/DOWN, etc.).
Go to step 8.
If the sound is normal, the USB device is OK
at this time. If the USB device cannot be operated,
go to USB audio device does not work.
8. Turn the ignition switch to LOCK (0).
9. Disconnect audio unit connector E (14P).
10. Disconnect USB adapter unit connector A (14P).

Special Tools Required
Electrical Noise Test
23-252
Audio System
Sound Quality Diagnosis (cont’d)
Diagnostics CD 07AAZ-SDBA100
Do this test to check for electrical noise being induced
into the audio system.
NOTE: Electrical noise may be caused by outside
sources that cannot be handled by the audio system.
Make sure you remove any cell phones and/or turn off
any aftermarket device before beginning this test.
1. Insert the diagnostics CD (T/N: 07AAZ-SDBA100) into the navigation unit or audio unit.
2. Play track No. 4 (digital zero) at a normal, or slightly higher than normal, volume level.
3. Operate any electrical device that may create electrical noise in the audio system, including
starting the engine.
4. Play track No. 5 (near digital zero) at a normal, or slightly higher than normal, volume level.
5. Operate any electrical device that may create electrical noise in the audio system, including
starting the engine.
6. Play track No. 6 (SNR) at a normal, or slightly higher than normal, volume level. 7. Operate any electrical device that may create
electrical noise in the audio system, including
starting the engine.
 If no abnormal noise is heard, go to individual speaker test.
 If the noise is present only during the SNR track, replace the navigation unit or audio unit.
 If the noise is heard during the digital zero or near digital zero track, check for;
– Poor ground for the audio unit, amplifier, engine or battery cable
– Pinched or shorted speaker or amplifier wire
– Faulty amplifier (Type S model)
– Faulty navigation unit
– Faulty audio unit
– Other faulty components causing excessive electrical noise (ignition coils, alternator, door
lock actuators, etc.). Disconnect any suspect
components, and then replay the tracks that
were originally noisy. If the noise is gone,
check the component’s circuit and the
component.

Self-Inertial Navigation LimitationsGlobal Positioning System (GPS) Limitations
23-266Navigation System
General Troubleshooting Information
Refer to the navigation system manual for the
navigation system operating procedures.
The navigation system and audio unit have a coded
theft protection circuit. Make sure you have the anti-
theft security code before:
 Disconnecting the battery.
 Disconnecting the navigation unit connector A (24P) and C (8P).
 Removing the No. 23 (10 A) fuse from the under-hood fuse/relay box.
After service, reconnect power to the navigation unit,
and turn the ignition switch to ON (II). Enter the 4-digit
anti-theft security code, then select Done.
If the code cannot be found, use the interactive Network
(iN) to look it up. You can view the serial number in one
of the ECU Info diagnostic screens (see page 23-305).
Alternatively, you can find the serial number on the
underside label which is located on the navigation unit
in the trunk.
When replacing the navigation unit, be sure to give the
customer the new anti-theft security code.
Certain circumstances and system limitations will result
in occasional vehicle positioning errors. Some client’s
may think this indicates a problem with the navigation
system when, in fact, the system is normal. Keep the
following items in mind when interviewing client’s
about symptoms of the navigation system.
The limitations of the self-inertial portion of the
navigation system (the yaw rate sensor and the vehicle
speed signal) can cause discrepancies between the
vehicle’s actual position and the indicated vehicle’s
position (GPS vehicle position). The following circumstances may cause vehicle
positioning errors:
 Moving the vehicle with the engine stopped and the vehicle stopped, such as by ferry or tow truck, or if
the vehicle is spun on a turn table.
 Tire slippage, changes in tire rolling diameters, and some driving situations may cause discrepancies in
travel distances. Examples of this include:
– Continuous tire slippage on a slippery surface
– Driving with snow chains mounted
– Abnormal tire pressure
– Incorrect tire size
– Frequent lane changes across a wide highway
– Continuous driving on a straight or gently curving highway
– Very bumpy roads
 Tolerances in the system and map inaccuracies sometimes limit how precisely the vehicle’s position
is indicated. Examples of this include:
– Driving on roads not shown on the map (map matching is not possible)
– Driving on a road that winds in one direction, such as a loop bridge, an interchange, or a spiral parking
garage
– Driving on a road with a series of sharp hair-pin turns
– Driving near a gradual highway exit or transition
– Driving on one of two close parallel roads
– Making many 90 degree turns
The GPS cannot detect the vehicle’s position or
elevation during the following instances:  For the first 5 to 10 minutes after reconnecting the battery (this process can take as long as 45 minutes).
 When the satellite signals are blocked by tall buildings, mountains, tunnels, large trees, inside
parking structures or large trucks.
 When the GPS antenna is blocked by metallic window tinting or by an object placed above it in the
vehicle. The GPS antenna requires a clear
unobstructed view of the sky.
 When there is no satellite signal output (signal output is sometimes stopped for sate llite servicing).
 When the satellite signals are blocked by the operation of some electronic aftermarket accessories
including, but not limited to non-OEM in-dash
entertainment units (radio, CD players/changers,
radar detectors and theft recovery systems) and cell
phones placed near the navigation system.
