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.

Electrical Noise Test

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.

Sound Quality Diagnosis (cont’d)
Diagnostics CD 07AAZ-SDBA100
Do this test to find rattles or reverberation that may
cause a perception of poor sound quality.
1. Insert the diagnostics CD (T/N: 07AAZ-SDBA100) into the navigation unit or audio unit.
2. Play track No. 13 (sweep from 500 Hz to 35 Hz) at a normal, or slightly higher than normal, volume
level.
3. Listen to each speaker for poor sound quality or reverberations caused by specific frequencies. Use
the voice-over to estimate the frequency that
causes the vibration. Use the audio unit’s fader and
balance settings to help isolate the channel with the
problem.
 If vibrations or poor sound quality are heard, go to step 4.
 If no vibrations or poor sound quality are heard, go to sound judging.
4. Choose the appropriate track from No. 14 to 25 (small range frequency sweep) or 26 to 53 (single
frequencies) to recreate the frequency that caused
the poor sound quality or vibration located in step
3: this aids in diagnosis of the cause.
NOTE: When you get to the track that recreates the
problem, select the repeat function on the
navigation unit or audio unit, this will help you
isolate the cause.
5. Replace or insulate the source of the vibrations or, if the speaker is the source of the poor sound
quality, replace it. Diagnostics CD 07AAZ-SDBA100
 Do this test to compare overall sound quality, imaging, and dynamics between the client’s vehicle
and a known-good vehicle. Only use a vehicle of the
same model and trim level for this test.
 Make sure the vehicle is using only OEM speakers.
1. In the client’s vehicle, set the bass, treble, fader, and balance settings to the client’s normal settings
that were written down before beginning testing.
2. Insert the diagnostics CD (T/N: 07AAZ-SDBA100) into the navigation unit or audio unit.
3. Play tracks No. 7 to 12 (sound quality, midland, dynamics, and imaging demonstration tracks) at a
normal, or slightly higher than normal, volume
level. Write down the volume setting being used.
4. Listen to areas of the track that stand out as being either very clear, or poorer than other areas of the
track.
5. Insert the diagnostics CD (T/N: 07AAZ-SDBA100) into the navigation unit or audio unit of a known-
good vehicle.
6. Play the tracks at the same volume level and the same bass, treble, balance, and fader settings as
used in step 3 in the client’s vehicle.
7. Listen to the same area of the track that stood out as being either very clear or poorer than other
areas of the track.
