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 DACMC (integrated into the ACM ) and the audio system speakers.

Remote Audio Controls

The audio system can be remotely controlled from the steering wheel.

SYNC™ System Overview

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:

  • Send and receive phone calls via a paired Bluetooth-enabled phone
  • Send and receive text messages via a paired Bluetooth-enabled phone
  • Connect media devices (such as an iPod®, USB device, or Bluetooth-enabled audio device to play audio files
  • Initiate a 911 Assist or emergency assistance call if the airbags deploy
  • Provide Vehicle Health Reports
  • Provide a vehicle Wi-Fi hotspot (if equipped, cellular subscription required)
  • Control smart devices using the cellular connection via an app (similar to using Alexa™ or Siri™)
  • Provide feedback to Ford about some of the SYNC relates systems
  • Provide over the air software updates

Not all SYNC system features are supported with every phone/device.

  • The vehicle owner can schedule the system to update wirelessly. The vehicle cannot be started or driven during the update process. The update does not occur unless a time is specified in the settings. Refer to the Owner Literature for details to update the vehicle wirelessly.

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.

Driver Assist Button

The driver assist button provides a quick means of bringing up the Settings Menu on the display unit.

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.

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. 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.

The emergency assistance feature is only available for vehicles in North America.

Audio System

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 can be amplified internally and sent directly to the speakers, or transmitted to a separate amplifier and speaker system.

The ACM (or the DSP if equipped with 13 or 19 speakers) 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.

ANC

The ANC system uses 3 microphones, the DACMC (integrated into the ACM ), PCM input and the audio system speakers.

The DACMC determines the noise frequency to be canceled based upon engine data and accelerator pedal position data from the PCM , as well as the input from the ANC microphones

While the engine is running, the ANC microphones (located in the headliner) monitor the engine noise resonating in the passenger compartment. The microphones transmit this noise as analog signals to the DACMC , where they are converted into digital signals. 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. This data is shared with the audio DSP module over the Automobile Audio Bus (A2B) cable. The final output by the ACM and the audio DSP module is sent as fluctuating AC voltage to the speakers.

Satellite Radio (if equipped)

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 .

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 Speaker Output - 11 Speaker System

The ACM is configured to directly power vehicle speakers. An amplifier in the final stage of the ACM sends an analog AC signal to drive the speakers. Output includes stereo and center channels. The ACM powers all of the vehicle speakers except the subwoofer speaker. A separate amplifier is used to amplify the audio signals to drive the subwoofer speaker.

A speaker circuit short to ground or power can be detected by the ACM . The ACM may disable speakers to prevent damage to the internal amplifier. A DTC sets to identify which speaker circuits are causing the concern.

ACM Signal/Speaker Output - 13 or 19 Speaker System

The ACM is configured to directly power some of the vehicle speakers. An amplifier in the final stage of the ACM sends an analog AC signal to drive the speakers. Output includes stereo and center channels to the instrument panel speakers.

The ACM outputs audio data over an Automobile Audio Bus (A2B) cable to the DSP . The DSP powers the remaining vehicle speakers. Output includes stereo 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.

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.

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 .

Voice Commands

When the steering wheel voice button is pressed, a CAN message from the SCCM 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 GPS antenna (integral to the satellite radio antenna) is used to acquire the compass heading.

The compass data is sent through the GPS cable to 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 . It can be updated using a USB flash drive. The APIM processes the data and transmits it to the display unit through the LVDS cable.

Connected Navigation (if equipped)

The TCU requires PMI when it is replaced.

APIM

The APIM consists of two internal modules: the CIP and the VIP . The modules are integrated into the APIM but can be programmed individually if required.

The CIP connects to user devices via Bluetooth, USB or Wi-Fi.

The VIP provides vehicle information for the CIP and other SYNC Apps or functions. In addition, the VIP obtains information from the modules on the network for Diagnostic Trouble Codes (DTCs) when a vehicle health report is requested.

Manual APIM Reset

Simultaneously press and hold the POWER button (in the middle of the volume button) and the RIGHT SEEK button on the FCIMB to reboot the APIM . As the APIM reboot begins, the display unit turns black before the startup sequence begins

APIM Programming

The APIM CIP or VIP software can be updated. When directed by Ford service, the VIP programming is done via the CAN using a diagnostic scan tool.

The CIP programming may be done using the diagnostic scan tool, Wi-Fi, over the air with the cellular network or the SYNC USB connection.

The CIP may also be programmed by registered owners using the Ford owner website. Updates can be scheduled to occur wirelessly or are written to a USB drive and taken to the vehicle USB for programming. After the update completes when using a USB drive, the APIM CIP writes the new software level and VIN back to the USB drive. The vehicle owner must transmit this information back to Ford via the internet.

BCM

The BCM contains the clock software and sends the date/time data information to other modules via the CAN .
