NOTE:
 Check the vehicle battery condition first.
 Check the XM radio reception in an open area. Poor reception/interference can be caused by nearby tall
buildings, mountains, or high-voltage power lines.
 Check the connectors for poor connections or loose terminals.
 If you can only tune to channel 000, 001, 174, and 247, make sure the navigation unit is set to channel mode
(see owners manual), if it is set to channel mode, call
XM Satellite Radio customer support, and check the
account activation status.

Left/Right Channel IDPhase Test
23-7423-74Audio System
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.

Individual Speaker TestSound Balance Test
23-7623-76Audio System
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.

Seek Stop Test
23-7823-78 Audio System
Sound Quality Diagnosis (cont’d)
8. Compare the client’s vehicle’s sound quality results
to 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 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 (Type S model)
– 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 23-39) 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.
