NOTE:
 Check the vehicle battery condition first.
 Check for aftermarket accessories plugged into the vehicle accessory power sockets (including cell
phone).
 Check the connectors for poor connections or loose terminals.
 Check the radio reception in an open area. Compare it to a known-good vehicle when ever possible.Poor
reception/interference can be caused by the
following:
– The radio station is far away.
– Atmospheric conditions are unfavorable.
– Tall buildings, mountains, or high-voltage power lines are nearby.
– Aftermarket metallic wi ndow tint.
1. Turn the ignition switch to ON (II).
2. Do the seek stop test (see page 23-78).
Multipath interference or weak station.
Operation is normal. Go to step 3.
3. Check if the radio reception/interference is the same in several locations.
Go to step 4.
Multipath interference or weak station.
Operation is normal.
4. Start the engine.
5. Check the reception/interference.
Check the antenna and radio grounds. If OK,
check the charging system and the ignition
system. Go to step 6.
6. Turn the ignition switch to LOCK (0). 7. Remove the right side C-pillar trim (see page 20-75).
8. Check the connections from the AM/FM antenna
amplifier to the window antenna.
Repair the connections, or substitute a
known-good AM/FM antenna amplifier and retest.
If the symptom/condition goes away, replace the
original AM/FM antenna amplifier (see page 23-87).
Go to step 9.
9. With the help of an assistant inside the vehicle, have the assistant shine a flashlight (A) along each
antenna wire (B). Check from the outside of the
vehicle for any breaks or openings in the antenna
wires (the light shines through).
Repair the window antenna. Go to AM/FM
antenna repair (see page 23-87), or replace the rear
window (see page 20-47).
Go to step 10.

Sound Quality Diagnosis
Diagnostics CD 07AAZ-SDBA100
Use the following tests to check sound quality.
NOTE: Before beginning the following tests, write down
the client’s bass, treble, fader and balance settings, and
then set them to their center positions for testing.
Do this test to confirm proper channel routing.
1. Insert the diagnostics CD (T/N: 07AAZ-SDBA100) into the navigation unit or audio unit.
2. Play track No. 1 (left, both, right channel ID) at a normal, or slightly higher than normal, volume
level.
3. The voice should be audible only from the channel or channels when indicated.
 If the channel ID is correct for each side, go to the phase test.
 If the channel ID is not correct, check for; – Shorted speaker wire
– Faulty amplifier (Type S model)
– Faulty navigation unit
– Faulty audio unit Diagnostics CD 07AAZ-SDBA100
Do this test to confirm proper speaker phasing.
1. Insert the diagnostics CD (T/N: 07AAZ-SDBA100) into the navigation unit or audio unit.
2. Play track No. 2 (phase) at a normal, or slightly higher than normal, volume level.
3. The voice should sound centered and focused when it is in-phase.
4. The voice should sound diffused, and have less bass when it is out of phase.
 If the voice changes from in-phase to out of phase as indicated by the prompt, the phasing is
correct. Go to electrical noise test.
 If the voice always sounds out of phase, phasing is not correct. Check for;
– Crossed speaker wires
– Faulty amplifier (Type S model)
– Faulty navigation unit
– Faulty audio unit

Electrical Noise Test
23-75
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 identify a faulty speaker.
1. Insert the diagnostics CD (T/N: 07AAZ-SDBA100) into the navigation unit or audio unit.
2. Play track No. 30 (steady 300 Hz tone) at a normal, or slightly higher than normal, volume level.
3. Listen to each speaker for poor sound compared to the other speakers. Use the audio unit’s fader and
balance settings to help isolate the channel with the
problem.
 If the sound quality produced by a specific speaker is poor, substitute it with a known-good
speaker. If the poor sound quality continues, go
to the sound balance test.
 If the sound quality is OK, go to the sound balance test. Diagnostics CD 07AAZ-SDBA100
Perform this test to identify a faulty channel or speaker.
1. Insert the diagnostics CD (T/N: 07AAZ-SDBA100) into the navigation unit or audio unit.
2. Confirm the bass and treble are set to the center positions.
3. Play track No. 3 (pink noise) at a normal, or slightly higher then normal, volume level.
4. A static type sound should be heard through all speakers.
5. Insert the diagnostics CD (T/N: 07AAZ-SDBA100) into the navigation unit or audio unit of a known-
good vehicle.
6. Set the bass and treble to the center position.
7. Play track No. 3 (pink noise) all the same level as wasplayedinstep3.
8. Compare the sounds made by the two vehicles.  If the noise sounds made by the two vehicles arevery similar, go to the Frequency Sweep Test
(see page 23-77).
 If the sound does not have as much bass, check the subwoofer and circuit.
 If the sound does not have enough hiss, check the tweeters and their circuits.

Frequency sweepSound judging
23-7723-77
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 customer’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.
