Component Description

Antenna

The roof-mounted antenna has an integrated antenna module that is powered by the ACM (Audio Control Module) to improve AM/FM (Amplitude Modulation/Frequency Modulation) reception.

Audio Input Jack

The audio input jack allows for a portable MP3 (Moving Pictures Experts Group -1 Audio Layer 3) player to be connected to the vehicle audio system utilizing a 1/8-inch audio jack.

Audio Control Module (ACM)

The ACM (Audio Control Module) 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 (Audio Control Module) requires PMI (Programmable Module Installation) when it is replaced.

Front Control Display Interface Module (FCDIM)

The FCDIM (Front Control/Display Interface Module) is a stand-alone module that displays infotainment system information. Information from the audio system and the climate control system are shown on the FCDIM (Front Control/Display Interface Module) display screen. The FCDIM (Front Control/Display Interface Module) requires PMI (Programmable Module Installation) when it is replaced.

Front Controls Interface Module (FCIM)

The FCIM (Front Controls Interface Module) is one of the customer interfaces to the audio system. It is separate from the ACM (Audio Control Module) and transfers button pressed data over a dedicated LIN (Local Interconnect Network) to the FCDIM (Front Control/Display Interface Module).

Steering Wheel Switches

The RH (Right Hand) upper steering wheel switch consists of a series of resistors. Each steering wheel control switch function corresponds with a specific resistance value within the switch. The FCDIM (Front Control/Display Interface Module) sends out a 5 volt reference voltage to the RH (Right Hand) upper steering wheel switch on the input circuits and monitors the voltage drop when a switch is pressed. The voltage drop varies depending upon the resistance of the specific switch pressed, providing indication to the FCDIM (Front Control/Display Interface Module) which switch is pressed.
