SYMPTOM TROUBLESHOOTING INDEX
Phase Test
Do this test to confirm proper speaker phasing.
- Insert the audio diagnostic CD (T/N: 07AAZ-SDBA100) into the audio unit.
- Play track No. 2 (phase) at a normal, or slightly higher than normal, volume level.
- The voice should sound centered and focused when it is in-phase.
- 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
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 device before beginning this test.
- Insert the audio diagnostic CD (T/N: 07AAZ-SDBA100) into the audio unit.
- Play track No. 4 (digital zero) at a normal, or slightly higher than normal, volume level.
- Operate any electrical device that may create electrical noise in the audio system, including starting the engine.
- Play track No. 5 (near digital zero) at a normal, or slightly higher than normal, volume level.
- Operate any electrical device that may create electrical noise in the audio system, including starting the engine.
- Play track No. 6 (SNR) at a normal, or slightly higher than normal, volume level.
- 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 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.
- Insert the audio diagnostic CD (T/N: 07AAZ-SDBA100) into the audio unit.
- Play track No. 30 (steady 300 Hz tone) at a normal, or slightly higher than normal, volume level.
- 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 «SOUND BALANCE TEST»(ref-290858-S10757117472008072200000) . If the sound quality is OK, go to «SOUND BALANCE TEST»(ref-290858-S10757117472008072200000) .
Sound Balance Test
Perform this test to identify a faulty channel or speaker.
- Insert the audio diagnostic CD (T/N: 07AAZ-SDBA100) into the audio unit.
- Confirm the bass and treble are set to the center positions.
- Play track No. 3 (pink noise) at a normal, or slightly higher then normal, volume level.
- A "static" type sound should be heard through all speakers.
- Insert the audio diagnostic CD (T/N: 07AAZ-SDBA100) into the audio unit of a known-good vehicle.
- Set the bass and treble to the center position.
- Play track No. 3 (pink noise) at the same level that was played in step 3 .
- Compare the sounds made by the two vehicles. If the noise sounds made by the two vehicles are very similar, go to «FREQUENCY SWEEP»(ref-290858-S26541680052008072200000) . 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
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 SPEAKER(S) (DISPLAY IS NORMAL) 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 ability of the audio unit to receive radio signals.
- Park the customer's vehicle in an open area away from buildings or other obstructions.
- Park a known-good vehicle (same year, model, and trim level) next to the customer's vehicle, facing the same direction.
- Start the engine in the customer's vehicle, and turn on the radio.
- Set the FM receiver to 87.7 MHz.
- Press the "Seek +" button and record the first station that the audio unit locks onto.
- Press the "Seek +" button repeatedly, and write down each station that the audio unit locks onto until the station recorded in step 5 is reached again.
- Set the AM receiver to 530 kHz.
- Press the "Seek +" button, and record the first station that the audio unit locks on to.
- Press the "Seek +" button repeatedly, and write down each station that the audio unit locks onto until the station recorded in step 8 is reached again.
- Turn the ignition switch to LOCK (0).
- Start the engine in the known-good vehicle, and then perform steps 4 through 10 on the known-good vehicle.
- Compare the number of stations received in steps 6 and 9 in the customer's vehicle with the number of stations received in the known-good vehicle. If the number of stations received is the same, or within 10%, the audio unit's tuner performance is OK. The problem may be atmospheric conditions, multi path interference, or other obstructions to the radio signal. If the customer's vehicle receives fewer stations by at least 10%, go to step 2 of poor AM or FM radio reception of interference (see «SYMPTOM TROUBLESHOOTING»(ref-290858-S10397747942008072200000) ).
