General Procedure

NOTE: If the Audio Control Module (ACM) is completely inoperative (does not power up), the part number decal on the Audio Control Module (ACM) chassis can be used to attain the Audio Control Module (ACM) part number.

Turn the Audio Control Module (ACM) on.
Operate the audio system in radio tuner (Amplitude Modulation/Frequency Modulation (AM/FM)) mode.
Press and hold the eject button, and within 1 second, press the seek up button until the speaker walk-around test begins.
- The display indicates each speaker as it is tested.

NOTE: If the speaker walk-around test is the only desired test, this procedure can be stopped after Step 3 by turning the Audio Control Module (ACM) off or by selecting exit using the audio system control buttons.

NOTE: The AHU Diagnostics refers to the Audio Control Module (ACM) and EFP Diagnostics refers to the Front Controls Interface Module (FCIM).

Once the speaker walk-around test is complete, the following information is available through the "BEZEL DIAGNOSTICS" menu using the audio system control buttons:
