SYMPTOM TROUBLESHOOTING CHART

Overview

The audio unit has a built in CD player. Audio units with navigation are referred to as audio-navigation unit. These units combine the audio system, the navigation system, and the CD/DVD player into one unit.

The audio unit acts as the processor for all audio functions. Select audio functions from the audio unit buttons or the audio remote switch (on the steering wheel). The center display provides the current audio status.

The audio unit has a built-in EEPROM (electrically erasable programmable read-only memory). This memory holds the audio presets (AM/FM radio frequency, sound settings, etc.) even when the battery is disconnected.

A security signal is daisy-chained between the audio and vehicle components for integration into the vehicle's security system.

There are two audio systems available for the Acura TSX

1. With navigation, it includes ELS audio system for surround sound with 10 speakers.
2. Without navigation, it includes premium audio system with 7 speakers.

AUDIO SYSTEM REFERENCE CHART

HDD Recording

The navigation system uses a HDD (hard disc drive) and can store music. To record music to the HDD, you must use an original CD or uncompressed CD-R files. The music must be loaded on a CD using the CD player. You cannot load music through the USB adapter or the auxiliary jack.

Song By Voice™ (with navigation)

You can use the voice control to operate the audio system, including the Song By Voice™ feature. See the Navigation Manual for more information.

Speed-Sensitive Volume Compensation (SVC)

All audio systems are equipped with speed-sensitive volume compensation (SVC). The audio-navigation unit or audio unit receives the vehicle speed pulse (VSP) from B-CAN. The system processes the speed input and increases the navigation or audio system volume level as the vehicle speed increases to compensate for the interior noise that occurs at higher speeds. When the vehicle slows down, the volume returns to its normal level. The SVC has four settings: SVC OFF, SVC LOW, SVC MID, and SVC HIGH that can be adjusted using the audio-navigation unit or audio unit. The factory default setting is SVC MID.

To change the audio unit SVC setting, press the MENU button to display the sound settings menu, then rotate the knob to adjust the SVC to the desired setting (SVC OFF, SVC LOW, SVC MID, or SVC HIGH).

To change the audio-navigation unit SVC setting, press the AUDIO button, and then select the Sound Setup from the AUDIO MENU on the navigation display. Rotate the interface dial to select the desired setting (SVC OFF, SVC LOW, SVC MID, SVC HIGH).

Active Noise Cancellation (ANC)/Active Sound Control System

Both the active noise cancellation (ANC) and active sound control are built into the ANC/active sound control unit. Both systems help eliminate unwanted sound from entering the passenger compartment. There are two microphones mounted in the headliner, one just behind the front overhead console and the other just ahead of the overhead rear light module. The microphones listen for low frequencies entering the passenger compartment and send a signal to the ANC/active sound control unit. The ANC/active sound control unit then creates a sound wave that is sent out through the speakers to eliminate the unwanted sound.

Active Noise Cancellation (ANC) System

The ANC system works to cancel engine booming sound up to about 2,000 RPM. The ANC/active sound control unit receives the engine speed pulse (NEP) from the PCM and outputs a sine-wave-sound through the audio speakers to cancel low-frequency noise from the engine. The ANC system also uses two microphones to detect and monitor low frequency noise in the passenger compartment. The microphones feed information back to the audio unit which adjusts the speaker output to reduce the noise. The ANC also receives input from the door open/close (INTR LT) signal from the MICU. Anytime a door is opened, the ANC system temporarily stops working.

Scheme 5

Active Sound Control System

The active sound control is the next generation of eliminating unwanted sound in the passenger compartment. The active sound control has a much broader range than the ANC system. In addition to the microphones in the headliner, the active sound control also receives input from the engine speed pulse (NEP) to provide various levels of sound cancelling depending on changes in the engine RPM.

Telematics Muting Logic

The navigation system provides voice control for the audio, the XM, and the CD player. Voice control commands are communicated through the GA-Net (audio unit). When using the TALK/BACK buttons or route guidance (RG), the center speaker is muted and you hear the navigation instructions through the front speakers. When using the HFL/AcuraLink, the center speaker, the rear speakers, and the subwoofer are muted and the front speakers give the telephone sound. When using the HFL/AcuraLink and the RG (Route Guidance) or the TALK/BACK buttons, the rear speakers are muted and you hear the telephone sound and navigation instructions through the front speakers. Muting commands are passed on the GA-Net bus. For more information, see the navigation section. The outline of the audio interruption function is shown in the following table.

TELEMATICS MUTING LOGIC REFERENCE CHART

Bluetooth Audio

Disc Handing and Cleaning

To avoid damaging or leaving fingerprints on a disc (CD, DVD, DVD-A, etc.), always handle it by the edges and place it in a jewel case whenever it is outside the audio or the audio-navigation unit. Deep scratches or fingerprints on the back of the disc can cause loading problems, poor sound quality, skipping, or other errors.

Scheme 12

Smudges and fingerprints can be carefully removed using a mild cleaner and tissues designed to clean eyeglasses. To clean a disc, use a clean soft cloth. Very gently wipe across the disc from the center to the outside edge, never in a circular motion.

Scheme 13

Do not place stabilizer rings or labels on the disc.

Special Tools Required

Diagnostic 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, then set them to their center positions for the testing.

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 Phase Test. If the channel ID is not correct, check for: Shorted speaker wire Faulty stereo amplifier Faulty audio unit

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 wire Faulty stereo amplifier Faulty audio unit

Electrical Noise Test

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 devices before beginning this test.

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. 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 at the audio unit, stereo amplifier, engine, or battery cable Pinched or shorted speaker or stereo amplifier wire Faulty stereo 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 channels. 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 Sound Balance Test. If the sound quality is OK, go to Sound Balance Test.

Sound Balance Test

Do 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 than 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 positions.
7. Play track No. 3 (pink noise) all the same level as was played in step 3 .
8. Compare the sounds made by the two vehicles. 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 Sweep

Do this test to find rattles or reverberations that may cause a perception of poor sound quality.

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

Sound Judging

Do this test to compare overall sound quality, imaging, and dynamics between the client's vehicle and a known-good vehicle. Only use a vehicle of the same model and trim level for this test.

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 the test.
2. Insert the audio diagnostic CD (T/N 07AAZ-SDBA100) into the 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. In a known-good vehicle, insert the audio diagnostic CD (T/N 07AAZ-SDBA100) into the audio unit.
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.
8. Compare the client's vehicle's sound quality results the known-good vehicle's results. If the sound quality in the client'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 create interference from the vibrations generated by the speakers Poor power or ground to the stereo amplifier Damaged speaker (s) Faulty stereo amplifier Faulty audio unit

Seek Stop Test

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 (display is normal); with ELS audio (see AUDIO SYSTEM SOUND IS WEAK OR DISTORTED (DISPLAY IS NORMAL) (WITH ELS AUDIO) ), with premium audio (see AUDIO SYSTEM SOUND IS WEAK OR DISTORTED (DISPLAY IS NORMAL) (WITH PREMIUM AUDIO) ), or No sound is heard from the speaker (s) (display is normal); with ELS audio (see NO SOUND IS HEARD FROM THE SPEAKER(S) (DISPLAY IS NORMAL) (WITH ELS AUDIO) ), with premium audio (see NO SOUND IS HEARD FROM THE SPEAKER (S) (DISPLAY IS NORMAL) (WITH PREMIUM AUDIO) ) before continuing with this test.

Note. Window tint, aftermarket theft-recovery devices and other aftermarket devices may affect reception. Changes in cloud cover and other atmospheric conditions will affect the ability of the 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 audio unit locks onto.
