Component Description: ACM
WARNING: This page is about a different car, the 2018 Lincoln Navigator. However, it is still accessible from the selected car via links, so may be relevant.
The ACM contains the CD player.
For vehicles equipped with the twelve speaker system, the ACM contains the DACMC. The DACMC performs noise canceling to reduce cabin noise.
The ACM and if equipped, the DACMC, require separate PMI procedures when the ACM is replaced.
