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 located in step 3 this 5. Replace or insulate the source of the vibrations or, if the speaker is the source of the poor sound quality, replace it. Special Tools Required Diagnostics CD 07AAZ-SDBA100 SOUND JUDGING Do this test to compare overall sound quality, imaging, and dynamics between the customer's vehicle and Make sure the vehicle is using only OEM speakers. 1. In the customer's vehicle, set the bass, treble, fader, and balance settings to the customer's normal settings that were written down before beginning testing. 2. Insert the audio diagnostic CD (T/N: 07AAZ-SDBA100) into the audio unit. NOTE: When you get to the track that recreates the problem, select the repeat
