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.

8. Compare the client’s vehicle’s sound quality results to the known-good vehicle’s results.
If the sound quality in the client’s vehicle is comparable to the sound quality in the known-
good vehicle, then the client’s vehicle is
operating as designed.
If the sound quality is not comparable, check these items in order.
– Loose or improperly installed speakers or other hardware that may become excited by
the vibrations generated by the speakers
– Poor power or ground to the stereo amplifier (Type S model)
– Damaged speaker(s)
– Faulty amplifier
– Faulty navigation unit
– Faulty audio unit Do this test to check the performance of the audio unit’s
AM and FM reception. Refer to symptom
troubleshooting: audio sound weak or distorted, or no
sound is heard from speakers (display is normal)
(see page 23-206) before continuing with this test.
NOTE:
Window tint, aftermarket theft-recovery devices and other aftermarket accessories may reduce radio
reception.
Changes in cloud cover and other atmosphere conditions will affect the ab ility of the navigation unit
or audio unit to receive radio signals.
1. Park the client’s vehicle in an open area away from buildings or other obstructions.
2. Park a known-good vehicle (same year, model, and trim level) next to the client’s vehicle, facing the
same direction.
3. Start the engine in the client’s vehicle, and turn on the radio.
4. Set the FM receiver to 87.7 MHz.
5. Press the Seek button and record the first station that the navigation unit or audio unit locks onto.
6. Press the Seek button repeatedly, and write down each station that the navigation unit or audio
unit locks onto until the station recorded in step 5 is
reached again.
7. Set the AM receiver to 530 kHz.
8. Press the Seek button, and record the first station that the navigation unit or audio unit locks
on to.
9. Press the Seek button repeatedly, and write down each station that the navigation unit or audio
unit locks onto until the station recorded in step 8 is
reached again.
