Audio Front Control Module (ACM)
WARNING: This page is about a different car, the 2012 Ford Fiesta. However, it is still accessible from the selected car via links, so may be relevant.
The Audio Front Control Module (ACM) can be operated while the key is in RUN or ACC. Additionally, the one hour mode feature allows the audio system to be operated for 1 hour when the ignition is transitioned to OFF and the ON/OFF button is pressed.
The ACM can produce its own DTCs, which can be communicated to the scan tool. The ACM communicates on the Infotainment Controller Area Network (I-CAN), with the Front Control/Display Interface Module (FCDIM) acting as the gateway to the Medium Speed Controller Area Network (MS-CAN).
