B1a16 Lincoln DescriptionWhen the VOICE switch is pressed, it changes a reference voltage signal, and the audio system enters voice recognition mode. The VOICE switch is wired to the Audio Control Module (ACM). The Accessory Protocol Interface Module (APIM) receives the microphone input and also broadcasts it to the ACM. The first voice commands spoken determine which system handles the voice commands.
The microphone test is available through the ACM self-diagnostic mode (navigation only). Running this test causes the ACM to produce a test tone. If the system is operating correctly, the microphone detects the tone and produces a signal to the ACM indicating the tone was heard. The OBDII set by the APIM during the on-demand self-test if it does not detect the microphone.
