Component Description: ACM
WARNING: This page is about a different car, the 2017 Lincoln Navigator and 2017 Ford Expedition. However, it is still accessible from the selected car via links, so may be relevant.
The ACM can be operated with the ignition in RUN, ACC, or OFF.
The ACM receives radio waves containing audio from the antenna coaxial cable(s) and converts them into fluctuating AC voltage. The ACM receives audio signals from the APIM in the form of fluctuating AC voltage. The ACM processes these inputs and sends left and right analog audio signals to the speakers as fluctuating AC voltage.
If equipped with satellite radio, the ACM will also receive radio waves containing data through the antenna coaxial cable(s). The data is sent to be displayed on the centerstack infotainment display.
The ACM requires PMI when it is replaced.
