NO -Replace the audio unit (see AUDIO UNIT REMOVAL/INSTALLATION ).

4. Turn the ignition switch OFF.

5. Remove the audio unit (see AUDIO UNIT REMOVAL/INSTALLATION ).

6. Measure the resistance between audio unit connector A (20P) No. 3 and No. 14 terminals as specified in

the table.

Is the resistance OK?

YES -Go to step 7.

NO -Repair open or high resistance in the circuit between the audio unit and the audio remote switch. If
the wires are OK, replace the cable reel (see CABLE REEL REPLACEMENT ).

7. Check for continuity between the No. 3 and No. 14 terminals of the audio unit connector A (20F1) and

body ground.

NOTE:

Eject all the CDs before remove the audio unit to prevent damaging the CD
player's load mechanism.

Is there continuity?

YES -Repair short to body ground in the circuit between audio unit and the audio remote switch. If the
wires are OK, replace the cable reel (see CABLE REEL REPLACEMENT ).

NO -Replace the audio unit (see AUDIO UNIT REMOVAL/INSTALLATION ).

SOUND QUALITY DIAGNOSIS

Special Tools Required

Diagnostics CD 07AAZ-SDBA100

Use the following tests to check sound quality.

LEFT/RIGHT CHANNEL ID

Do this test to confirm proper channel routing.

1. Insert the audio diagnostic CD (T/N: 07AAZ-SDBA100) into the 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 (with premium sound system)



Faulty audio unit

NOTE:

Before beginning the following tests, write down the bass, treble, fader and
balance settings, and then set them to their center positions for testing.

PHASE TEST

Do this test to confirm proper speaker phasing.

1. Insert the audio diagnostic CD (T/N: 07AAZ-SDBA100) into the 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



Faulty audio unit

Special Tools Required

Diagnostics CD 07AAZ-SDBA100

ELECTRICAL NOISE TEST

Do this test to check for electrical noise being induced into the audio system.

1. Insert the audio diagnostic CD (T/N: 07AAZ-SDBA100) into the 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.

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.



If the noise is present only during the SNR track, replace the 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



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.

INDIVIDUAL SPEAKER TEST

Do this test to identify a faulty speaker.

1. Insert the audio diagnostic CD (T/N: 07AAZ-SDBA100) into the 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.

Special Tools Required

Diagnostics CD 07AAZ-SDBA100

SOUND BALANCE TEST

Perform this test to identify a faulty channel or speaker.

1. Insert the audio diagnostic CD (T/N: 07AAZ-SDBA100) into the 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 audio diagnostic CD (T/N: 07AAZ-SDBA100) into the audio unit of a known-good vehicle.

6. Set the bass and treble to the center position.

7. Play track No. 3 (pink noise) at the same level that was played in step 3.

8. Compare the sounds made by the two vehicles.
