Component Description
ACM
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 and converts them into fluctuating AC voltage. The ACM processes these inputs, and sends stereo analog audio signals to the speakers as fluctuating AC voltage.
The ACM requires PMI when it is replaced
Antenna
The AM/ FM radio uses the fixed-mast fender-mounted AM/ FM antenna to receive analog radio waves. The radio waves are sent through the AM/ FM antenna coaxial cable to the ACM, where they are amplified.
If equipped, the satellite radio uses the roof-mounted satellite radio antenna to receive signals containing digital audio and data. These signals are sent through the satellite radio antenna coaxial cable to the satellite radio receiver built into the ACM.
Audio Input Jack
The audio input jack can be used to play audio files from an audio device connected through the 1/8-inch (3.5 mm) audio jack.
Audio signals are sent from the audio input jack to the ACM.
There are no power or ground circuits to the audio input jack.
FCDIM
The FCDIM can be operated with the ignition in RUN, ACC, or OFF.
The FCDIM displays infotainment data received from various modules over the CAN. If the FCDIM loses the signal from any of these modules, only those specific displays will be inoperative. For more information, Refer to: Information and Entertainment System - System Operation and Component Description . See Module Network Input Messages - FCDIM.
The FCDIM requires PMI when it is replaced.
FCIM
The FCIM audio functions can be operated with the ignition in RUN, ACC, or OFF.
The FCIM audio system buttons provide one of the methods with which the customer interacts with the infotainment system.
The FCIM is separate from the ACM.
The FCIM requires PMI when it is replaced.
Noise Suppression Equipment
The radio frequency suppression equipment reduces interference transmitted through the speakers by the engine, ignition, and electrical systems. When installing any new radio suppression equipment components, make sure that a good contact is made at all connections.
