Audio Control Module (ACM)
WARNING: This page is about a different car, the 2005 Lincoln LS. However, it is still accessible from the selected car via links, so may be relevant.
The ACM is connected to the SCP communications network and also to the audio control protocol (ACP) communications network. The ACM communicates with the compact disc player/changer using the ACP. The ACM uses the SCP communications network for diagnostics. For additional information on the ACM and the compact disc player/changer, refer to AUDIO UNIT .
