AUDIO SYSTEM SOUND QUALITY DIAGNOSIS
Special Tools Required
Diagnostic CD 07AAZ-SDBA100
Use the following tests to check sound quality.
NOTE:
Before beginning the following tests, write down the bass, the treble, the
fader and the balance settings, and then set them to their center positions
for testing.
Always verify the customer's complaint, and compare it a known-good
vehicle of the same model and trim under the same conditions using the
same inputs (iPod, USB device, etc.). If the complaint is the same on the
known-good vehicle, it is a system characteristic.
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-navigation unit or 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 PHASE TEST.
If the channel ID is not correct, check for:
Shorted speaker wire
Faulty audio-navigation unit or audio unit
Faulty stereo amplifier
Shorted speaker
Open in speaker wire
Loose pins or poor pin fit in the speaker circuit
PHASE TEST
Do this test to confirm proper speaker phasing.
1. Insert the audio diagnostic CD (T/N 07AAZ-SDBA100) into the audio-navigation unit or 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 indicates it is in-phase.
4. The voice should sound diffused, and have less bass when it indicates 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.
