Active Noise Control Mic Location?

[Relak]

I've looked in the rear headliner and the map lighting compartment up front but have had no luck in identifying the so called "ANC Mics'" locations. Has anyone actually found this in their GT350s and been able to disconnect them?

Whut?

The wiring diagram for the GT350 doesn't show any ANC mics or other components, so I think it's safe to say that you can't find them because they aren't there.

The Ecoboost cars may have subtractive noise shaping, but the GT350's only have enhancement through the Audio Control Module.

well that makes sense then. I read this on another forum and I guess after looking at the ford service manual it says that the 2.3l's have the mics AND the DADMC, and the 5.2's only have the DACMC which run the ANC. I'm just trying to figure out how to turn off the ANC since it didn't seem to work in forscan:

Active Noise Control

Active noise control is an audio system feature that eliminates some of the low frequency engine noise within the passenger compartment typically induced under wide open throttle or heavy part-throttle conditions. The system uses 3 microphones, a DACMC, and the audio system speakers. The DACMC determines the noise frequency to be canceled based upon engine rotation speed data from the PCM and the microphone input signals.

While the engine is running, the active noise control microphones located in the front and rear of the headliner monitor the engine noise resonating in the passenger compartment. The microphones transmit this noise as analog signals to the DACMC, where they are converted into digital signals by the integrated analog/digital converter. The digital signals are processed and an inverted phase sound wave with the same amplitude as the original sound is created. This new sound is converted into an analog audio signal and output by the DACMC internal tone generator to all of the speakers except the instrument panel center speaker (if equipped).

Is all of that still occurring when the audio system is powered off?

Negative. Only when the audio system powers up either on ACC or engine on.

if you had ANC you disable it buy open the trunk or drivers door.

We have fake noise see that post service manual clips
