Diagnostics CD 07AAZ-SDBA100
Do this test to find rattles or reverberations that may
cause a perception of poor sound quality.
1. Insert audio diagnostic CD (T/N 07AAZ-SDBA100)
into the CD player.
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 is heard, go to
step 4.
• If no vibrations or poor sound quality is heard, go
to sound judging (see page 23-54).
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 audio
unit, this will help you isolate the cause.
5. Replace or insulate the source of the vibration 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 customer’s vehicle and a
known-good vehicle. Only use a vehicle of the same
model and trim level for this test.
1. In the customer’s vehicle, set the bass, treble, fader,
and balance settings to the customer’s normal
settings that were written down before beginning
testing.
2. Insert audio diagnostic CD (T/N 07AAZ-SDBA100)
into the CD player.
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 audio diagnostic CD (T/N 07AAZ-SDBA100)
into the CD player 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 customer’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 customer’s vehicle’s sound quality
results the known-good vehicle’s results.
• If the sound quality in the customer’s vehicle is
comparable to the sound quality in the known-
good vehicle, then the customer’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
– Damaged speaker(s)
– Faulty amplifier
– 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 23-28) 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 ability of the audio unit to
receive radio signals.
1. Park the customer’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 customer’s vehicle, facing the
same direction.
3. Start the engine in the customer’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 audio unit locks onto.
6. Press the ‘‘Seek
’’ button repeatedly, and write
down each station that the 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 audio unit locks onto.
9. Press the ’’Seek
’’ button repeatedly, and write
down each station that the audio unit locks onto
until the station recorded in step 8 is reached again.

10. Turn the ignition switch to LOCK (0).
11. Start the engine in the known-good vehicle, and
then perform steps 4 thru 10 on the known-good
vehicle.
12. Compare the number of stations received in steps 6
and 9 in the customer’s vehicle with the number of
stations received in the known-good vehicle.
• If the number of stations received is the same, or
within 10 %, the audio unit’s tuner performance
is OK. The problem may be atmospheric
conditions, multi path interference, or other
obstructions to the radio signal.
• If the customer’s vehicle receives fewer stations
by at least 10 %, go to step 2 of poor radio
reception of interference (see page 23-24).

SRS components are located in this area. Review the
SRS component locations (see page 24-14), and the
precautions and procedures (see page 24-16) before
doing repairs or service.
NOTE:
• Put on gloves to protect your hands.
• Take care not to scratch the dashboard and related
parts.
• Lay a workshop towel under the parts when working
on them to protect the face panel from scratches or
other damage.
• Eject all the CDs before removing the audio unit and
CD changer to prevent damaging the CD player’s load
mechanism.
• If you are replacing the audio unit, write down the
audio presets (if possible), and enter them into the
new audio unit.
1. Make sure you have the anti-theft codes for the
audio system and the navigation system (if
equipped).
2. Remove the instrument panel (see page 20-81).
3. Remove the bolts, then pull out the audio unit (A)
and navigation display (B) (with navigation) or
center pocket (C) (without navigation).
4. Disconnect the connectors (D), then remove the
audio unit.
