Component Description: ACM
WARNING: This page is about a different variant/trim than selected.
The ACM can be operated with the ignition in RUN or ACC. The accessory delay feature allows the audio system to be operated for a preset period of time after the ignition is turned off and a front door has not been opened. The ACM requires Programmable Module Installation (PMI) when it is replaced.
For vehicles without active noise control, the ACM provides the audio signals to the subwoofer amplifier and all speakers.
For vehicles with active noise control, ACM provides the audio signals to the subwoofer amplifier, the instrument panel speaker and the DACMC . The DACMC processes the audio signals with the noise cancellation signals and provides the door speakers with the amplified audio signals.
