Audio Input Jack Mode

While the engine is running, the ANC microphones located in the overhead console and center rear of the headliner (coupe), or overhead console, RHR quarter panel, and LHR quarter panel (convertible) monitor the engine noise resonating in the passenger compartment. The microphones transmit this noise as analog signals to the DACMC (contained within the ACM), where they are converted into digital signals by the integrated analog/digital converter. The digital signals are processed and an inverted phase sound wave with the same amplitude as the original sound is created. This new sound is converted into an analog audio signal, transmitted to the DACMC internal tone generator, and 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.

Audio Input Jack Mode

When a portable audio device, such as an iPod® with its available cable, is connected to the vehicle audio system through the audio input jack, audio from the device can be played through the vehicle speakers. Only the volume can be controlled with the vehicle audio controls. All other functions such as seek, fast forward, pause, etc. must be carried out on the device itself.

No metadata (information such as artist, album title, song title, and genre) is transmitted when a device is connected to the audio input jack.

Battery Load Shed

The BCM uses the battery current sensor to monitor the battery state of charge. The battery current sensor is attached to the battery ground cable. With the ignition in RUN, ACC, or OFF, a load shed message is sent over the CAN when the BCM determines that the battery state of charge is below 40%, 45 minutes have elapsed, or 10% of the charge has been drained. This message turns off the audio system to save the remaining battery charge. Under this condition, "Battery Saver - System Off" is displayed on the FCDIM to notify the driver that battery protection actions are active. To clear the load shed state, start the vehicle.

Bluetooth Mode

Bluetooth is a secure, short-range radio frequency that allows devices to communicate wirelessly through radio waves. The operating range of a Bluetooth signal is application specific, but will have a minimum range of 10 meters (33 feet).

The APIM Bluetooth chipset supports multiple Bluetooth profiles, allowing the SYNC® system to interact with both Bluetooth-enabled phones and Bluetooth-enabled media devices.

Any Bluetooth-enabled device used with the SYNC® system must first be paired with the APIM Bluetooth chipset before it can become operational. Pairing a Bluetooth-enabled device is accomplished through the "Add Device" selection of the phone menu. When pairing a device, the SYNC® system generates a unique PIN that must be entered on the Bluetooth-enabled device in order for the pairing process to be successful. There are also some device-specific actions that must take place. For information on the pairing process, refer to the Owner's Literature.

Multiple Bluetooth-enabled phones and Bluetooth-enabled media devices can be paired to the APIM at the same time. The APIM supports an active connection with one Bluetooth-enabled phone and one Bluetooth-enabled media device at a time. If an additional device of either type is paired and made active, the APIM ends any active connection with an already-paired device, and establishes an active connection with the new device.

It is important to understand that while most Bluetooth-enabled devices can pair with the SYNC® system, not all Bluetooth-enabled devices have the same level of available features when interacting with the SYNC® system. To determine if a Bluetooth-enabled device or feature is supported, review the device compatibility list. Refer to owner.ford.com/how-tos/sync-technology/all/phone-setup/how-your-device-works-with-sync.html?version=sync.

For more information, refer to “Bluetooth” in the Owner's Literature.

Chimes

Various vehicle systems send chime requests over the CAN to the IPC. The following are determined as the IPC processes these requests:

Chime characteristics such as tone, tone length, number of repetitions, and time between tones Chime output volume Priority of the chime request Which speakers (all, front, or rear) will play the specific chime
