Audio Input Jack

to be read from the FCDIM and/or device while driving. Examples include incoming text message sender information, text messages, and metadata from audio being played via USB or Bluetooth.

The APIM consists of two internal modules: the CIP and the VIP. The modules are not replaceable individually, but can be programmed independently if required.

The CIP interfaces with all of the customer inputs to the APIM. It contains an analog-to-digital-to-analog converter, as well as the Bluetooth chipset.

The VIP provides an interface between the CIP and the vehicle inputs. Its main functions are controlling the APIM power management and translating inbound and outbound CAN signals.

The APIM requires programming when it is replaced.

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 APIM.

There are no power or ground circuits to the audio input jack.

DACMC - 2.3L Or 5.2L

The DACMC ANC and ESE functions only operate while the engine is running, and the luggage compartment lid and all doors are closed.

The DACMC is a digital signal processor that consists of an internal analog/digital converter and tone generator.

For ANC, the DACMC uses engine rotation speed data, engine torque data, accelerator pedal position data, and ANC microphone input signals to calculate the targeted frequency needed to cancel engine noise within the passenger compartment. For ESE, the DACMC uses engine rotation speed data, engine torque data, and accelerator pedal position data from the PCM to calculate the targeted frequency needed to enhance engine noise within the passenger compartment. The DACMC engine noise cancellation signals are output by the ACM to the LHF and RHF door midwoofer speakers, and left and right parcel shelf full-range speakers (coupe) or RHR and LHR quarter panel full-range speakers (convertible) as fluctuating AC voltage. The DACMC ESE frequency signals are output by the ACM to the LHF and RHF door midwoofer speakers as fluctuating AC voltage.

When the engine is running and the audio system is in use, the ACM fluctuating AC voltage output signals to the LHF and RHF door midwoofer speakers, and left and right parcel shelf full-range speakers (coupe) or RHR and LHR quarter panel full-range speakers (convertible) contain a mixture of the engine noise cancellation and ESE frequency with the audio signals.

The DACMC is contained within the ACM.

The DACMC and ACM require separate PMI procedures when the ACM is replaced.

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 (415-00A Information and Entertainment System - General Information - Vehicles With: AM/FM/CD/SYNC, Description and Operation). 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 through which the customer interacts with the infotainment system.
