System Operation
Audio System Overview
NOTE: Refer to the Owner Literature for additional details of the audio system.
AM / FM Radio
The ACM can operate when the ignition is on or off. The accessory delay feature powers the audio system, after the ignition has been turned off, for a preset time or until a front door is opened. The ACM is connected to the vehicle network, so a scan tool can be used in diagnostics.
When the AM / FM mode is selected, the ACM amplifies the radio waves sent from the antenna. It then selects the requested frequency, converts and amplifies the content. The ACM outputs the signals to the speakers, or to the separate DSP (amplifier).
Radio stations may broadcast RDS signals which contain information such as station identification and program information. Radios equipped with RDS can extract this information and also target the station genre (music type, such as Rock) for seek or scan functions.
High Definition (HD) Radio or DAB Radio (if equipped)
HD or DAB radio is a free service offered by some radio stations, enabling them to broadcast better sound quality with multiple programs on a single radio frequency.
A DAB -equipped radio also receives data for the traffic announcement services. Due to the higher broadcast frequencies, DAB requires a different antenna from the standard AM / FM antenna.
DAB equipped-radios are not available in North America.
Satellite Radio (if equipped)
Satellite radio is a subscription-based service which broadcasts various programs without commercials. The satellite-transmitted signal contains station identification and various program information, including genre and song titles. A satellite equipped radio can display or use this information along with the programming.
Satellite radio receivers contain a required ESN which registers the radio and vehicle with the satellite company.
With an active "All-Access" satellite radio subscription, SIRIUS™ streaming content (includes streaming data) is available.
Extended Audio Play Feature
Extended audio play allows the audio system to operate with the ignition off. When the power button is pressed, the audio system activates and remains active for a period of up to 30 minutes. Extended audio play does not function if the battery load shed is active. Opening a door does not affect the extended audio play feature.
Battery Load Shed Feature
The audio system turns off after periods of engine-off activity with low battery state of charge. The display shows Battery Saver - System Off. Restarting the engine and recharging the battery resets the load shed feature.
Chimes
The audio system broadcasts chimes and other driver alerts sent by various vehicle systems.
For specific chime information,
Refer to: Warning Chimes -
System Operation and Component Description (413-01 Instrumentation,
Message Center and Warning Chimes, Description and Operation).
Speed Compensated Volume Feature
The adjustable speed-compensated volume can be turned off or set to increase audio system playback level as the vehicle speed increases.
ANC (if equipped)
ANC is an audio system feature that reduces the level of occasional low frequency engine noises which compete with audio system playback. The system uses 3 microphones, the ACM and the audio system speakers.
Remote Audio Controls
The steering wheel switches can control some audio system functions. The steering wheel switch consists of multi-button switches that operate various audio system controls.
Rear Audio Controls
The RACM can control some audio system functions from the second row seat. It is located on the rear of the front floor console or in the rear seat center armrest. Users can remotely adjust volume, seek, media source or the clock display.

NOTE: Refer to the Owner Literature for additional details of the SYNC system.
NOTE: It may be necessary on occasion to carry out a master reset of the SYNC system for correct operation. Accumulated data uploaded from devices may corrupt the SYNC software and resetting the SYNC system clears this data to allow normal operation of the SYNC system.
The SYNC system is a hands-free communication and entertainment system and provides the following functions:
Not all SYNC system features are supported with every phone/device.
When the automatic system updates is enabled, an icon displays on the screen. Tapping the icon brings up prompts to update the vehicle.
Once the update download and installation is complete, an ignition cycle must occur before the update becomes active.
Remote SYNC Controls
The steering wheel switches can control some SYNC system functions. The steering wheel switch consists of multi-button switches that operate various SYNC functions.
Bluetooth Mode
Bluetooth is a secure, short-range (up to 10 meters (33 feet)) wireless connection method used for wireless device communication with the SYNC system. The SYNC system supports multiple Bluetooth profiles, allowing the SYNC system to interact with Bluetooth enabled phones and Bluetooth-enabled media devices. While most Bluetooth-enabled devices can pair with the SYNC system, not all Bluetooth-enabled devices have the same level of SYNC-compatible features. To determine if a Bluetooth-enabled device or feature is supported, refer to the list of compatible devices and features at the Ford authorized website.
Multiple Bluetooth-enabled phones and Bluetooth-enabled media devices can be paired to the SYNC system at the same time. The SYNC system 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 SYNC system ends any active connection with an already-paired device and establishes an active connection with the new device.
Dual Phone
The dual phone feature allows the vehicle owner to select between 2 paired phones to make calls or send texts. Only one phone at a time can be actively in a call through the SYNC system.
USB Mode
Connecting a portable media device mass storage device (such as a MP3 player or USB flash drive) to a USB port allows media files to be played through the audio system. Playback functions (volume, seek, fast forward, pause) can be controlled with the vehicle audio controls.
SYNC can use media with embedded information (artist, album and song titles, and genre) for search and playback functions, if it is supported and correctly formatted on the media device.
When a new media device is connected, SYNC records where the information resides and uses this information to quickly find requested songs. Indexing the media information and location can take several minutes if the size of the media is large. Future changes to indexed media are updated rather than replacing the entire index, which greatly reduces the time required.
Media files that do not have DRM protection or are not properly formatted on the device, cannot be played on the SYNC system.
Two USB ports in the media hub allow connection and playback of portable media devices and SYNC software updates. The media hub provides standard 5 volt power and charging of portable devices.
SYNC AppLink
The SYNC AppLink supports devices with third party installed applications capable of outside control by voice command, the steering wheel switches, the audio control panel or the display unit. These devices must be paired with SYNC Bluetooth and some devices require a USB connection.
Voice Command
The SYNC voice command capability reduces or eliminates physical interaction with certain vehicle functions or portable device controls. When SYNC is prompted by the steering wheel switch, it responds with a tone or audible response (depending on the SYNC setting) in the audio system. SYNC uses the voice microphone to listen to the driver command and control the vehicle function or portable device.
A wake word can also be used to activate the SYNC system.
Text-To-Speech Feature
The SYNC text-to-speech feature converts text information to speech and broadcasts it through the audio system. Text messages with sender information, media titles, and other information can be read and broadcast through the audio system, helping users maintain driving focus.
Emergency Assistance (911 Assist)
The emergency assistance feature (911 Assist) calls for help in an event where the airbags deploy. This feature must be previously enabled and requires a paired cellular phone to connect with emergency services. If activated by an airbag deployment, the system plays a message in the vehicle indicating an emergency call is about to be placed. If not canceled, it dials the emergency response number and plays a pre-recorded message for the emergency response operator. After the message plays, the vehicle occupant(s) can talk with the operator to give their location and personal information.
Compass
Information from the GPS determines the vehicle compass heading. The compass heading displays in the IPC message center or the center display unit.
Navigation System (if equipped)
NOTE: It may be necessary on occasion to carry out a master reset of the SYNC system for correct operation. Accumulated data uploaded from devices may corrupt the SYNC software and resetting the SYNC system clears this data to allow normal operation of the SYNC system.
The navigation system uses GPS to display the vehicle location and travel direction on a map, displayed on the touchscreen. Street names, landmarks, and points of interest are included. The driver can enter destination information to obtain automatic map routing and navigation guidance voice directions. This include features such as trailer optimized navigation routing and Live Traffic. Refer to the Owner Literature for details of the all the SYNC navigation system features.

NOTE: Refer to the Owner Literature for additional details of the audio system.
ACM Operation
The ACM receives and sends network messages over the CAN . A diagnostic scan tool can retrieve Diagnostic Trouble Codes (DTCs), PID data and carry out other diagnostic functions for the ACM via the vehicle DLC .
The ACM is powered at all times and uses the ignition status message to control the on/off mode. The accessory delay feature is controlled by an ignition status message from the BCM .
The ACM uses various inputs such as radio waves and audio signals, conditions, amplifies and converts them to an analog audio signal. This signal is transmitted to a separate amplifier and speaker system.
The ACM uses the BCM ignition status message to temporarily mute audio output during engine cranking. This prevents the normal voltage spikes during engine cranking from producing popping noises in the audio system.
The DSP receives vehicle speed information from the PCM over the CAN to adapt the volume based on the different vehicle speeds.
AM / FM / DAB Radio
When the AM / FM mode is selected, the radio amplifies radio waves sent from the antenna. It then selects the requested frequency, converts and amplifies the content. These fluctuating audio signals are output as AC output voltage to power the speakers or as an input to a separate amplifier.
If equipped with High Definition (HD) radio capability, the radio automatically detects and plays back the improved sound quality and multiple programs of HD broadcasts. HD-equipped radios use the existing standard AM / FM antenna for signal reception. If a concern only exists for the HD radio feature, refer to the troubleshooting guide within the Owner Literature.
If equipped with DAB capability, the radio can provide improved sound quality and multiple programs of digital broadcasts.
DAB -equipped radios are not available in North America.
Satellite Radio (if equipped)
Some satellite data is communicated between the APIM and the ACM over dedicated circuits to show as information on the center display screen.
Satellite signals collected by the satellite radio antenna can be selected and played back over the audio system. The satellite antenna sends satellite radio and GPS data through the satellite radio cable to a splitter (integrated into the cable). The satellite radio signals are separated by the splitter and sent to the satellite radio receiver within the ACM .
Some satellite data is communicated between the APIM and the ACM over dedicated circuits to show as information on the center display screen.
Streaming content (including On Demand) is received by the TCU from the cellular network. The TCU sends this data to the APIM over the Ethernet cables via the GWM .
The satellite radio feature is only available in North America.
SYNC Input
The ACM receives stereo and monaural audio wired inputs from the SYNC system. These include USB or Bluetooth connected music sources, phone call audio, and more.
When the USB input mode is selected, the radio converts the digital media playback to analog audio signals. It amplifies and sends this output to the speakers.
If a compatible phone is paired with the SYNC system, phone call audio may be heard on the vehicle speakers and the spoken response is transmitted to outgoing phone call audio.
ACM Signal/Speaker Output
The ACM is configured to power none of the vehicle speakers.
The ACM outputs audio data over an Automobile Audio Bus (A2B) cable to the DSP . The DSP powers all of the vehicle speakers. Output includes stereo, center and subwoofer channels.
A speaker circuit short to ground or power can be detected by the ACM and the DSP . The ACM and the DSP may disable speakers to prevent damage to the internal amplifier. This may cause all audio to be inoperative. A DTC sets to identify which speaker circuits are causing the concern.
ANC (if equipped)
The ANC feature reduces the level of occasional low frequency engine noises which compete with audio system playback.
The ACM determines the noise frequency to be canceled from the sound present inside the vehicle and by using engine data from the PCM .
While the engine is running, the ANC microphones monitor undesired noise in the passenger compartment. The microphones transmit this noise as analog signals to the ACM . The signals are processed to create an inverted phase sound wave with the same amplitude as the original sound. This noise-canceling sound, created by the ACM , outputs to the DSP over the Automobile Audio Bus (A2B) cable. The final output by the ACM and the DSP is sent as fluctuating AC voltage to the speakers.
Remote Audio Controls
The steering wheel switches contain a series of resistors. Each steering wheel audio function switch has a specific resistance value. The SCCM and switch assembly are connected in a voltage divider circuit. The voltage drop over an internal SCCM resistor is changed by the different audio switch function resistances. The SCCM monitors the voltage drop across its internal resistor to determine which steering wheel switch is pressed. The SCCM transmits the steering wheel switch inputs over the CAN to the ACM , to control audio functions.
Rear Audio Controls
The RACM communicates the audio system requests over the CAN to the ACM .
SYNC System
NOTE: Refer to the Owner Literature for additional details of the SYNC system.
The APIM contains the SYNC software. The SYNC system connects various inputs over Bluetooth or USB connections to the car audio system. The SYNC system allows driver control of a phone, media device, and vehicle systems (navigation and climate control for example).
The APIM is powered at all times and uses the BCM ignition status message to control the on/off mode. The accessory delay feature is controlled by an ignition status message from the BCM .

USB Mode
The APIM receives serial data input from connected USB devices. The USB cables to the APIM are shielded to prevent interference from electromagnetic sources. The APIM provides 5 volt power for the USB port in the media hub.
Voice Commands
When the steering wheel voice button is pressed, a CAN message is sent to the APIM , initiating the voice command feature.
When voice commands are spoken, the monitored sounds are converted into analog signals by the microphone and sent to the APIM . The APIM software interprets them and outputs a command.
Compass
The compass data is received through the GPS cable by the APIM . The APIM uses this data in addition to wheel speed and wheel rotation direction messages from the ABS module to calculate and provide accurate vehicle tracking. The APIM processes the data and transmits it through the LVDS cable to the display unit. In the event the GPS fix or signal is temporarily lost, the APIM continues to use CAN messages from the ABS module to maintain compass accuracy.
Navigation (if equipped)
The APIM receives GPS data from the satellite and the GPS antenna via a coaxial cable. The GPS data is used for the compass heading, vehicle location (in the event of airbag deployment) and navigation guidance. The APIM uses the GPS data along with ABS module wheel speed and rotation direction to provide accurate navigation tracking. In situations where the GPS signal is temporarily lost, the APIM continues to use the ABS module and vehicle acceleration data to continue vehicle tracking.
The navigation map data is stored in the APIM . The APIM processes the data and transmits it to the display unit through the LVDS cable. The map can be updated using a a Wi-Fi access point.
Connected Navigation (if equipped)
NOTE: To identify if the vehicle is equipped with a built-in navigation system, click on the "ADDITIONAL INFORMATION" link on the OASIS tab on PTS . Built-in navigation is identified by the code HKCAB.
