Audio System

NOTE: Refer to the Owner Literature for additional details of the audio system.

ACM

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 12 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

The ACM can operate when the ignition is on or off.

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.

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.

High Definition (HD) Radio or DAB Radio (if equipped)

High Definition (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 digital radio data link 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.

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.

The satellite radio feature is only available in North America.

ANC (if equipped)

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 DSP is sent as fluctuating AC voltage to the speakers.

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.

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 - Except 12 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 speakers (11 speaker system). A separate amplifier is used to amplify the audio signals to drive the subwoofer speakers.

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 - 12 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.

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)

Not all SYNC system features are supported with every phone/device. Review the Ford authorized website list of compatible devices to determine if the SYNC system supports a specific phone, tablet, media player or a feature of one of those devices.

The vehicle owner can update the SYNC system (CIP) using a USB flash drive or a Wi-Fi connection not requiring a browser sign in or two-step security validation. If using a flash drive, a minimum of 32 GB of memory is recommended.

  • When the SYNC system is connected to a stationary Wi-Fi network (such as a home or restaurant) for automatic updates, the update download occurs when the ignition is off. To limit battery drain, the SYNC system downloads the update for up to 150 minutes in a month for a maximum of 30 minutes at a time.
  • When the SYNC system is connected to a mobile Wi-Fi hotspot (network) for automatic updates, the update download can occur when the ignition is in the ON/RUN mode.

Once the update download and installation is complete, an ignition cycle must occur before the update becomes active.

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.

SYNC Inputs

  • USB - media players or flash drives
  • Bluetooth - phones or media players
  • Display unit and radio control panel switches
  • Steering wheel switches
  • Voice microphone input
  • GPS data
  • Serial data link wired input from the ACM
  • Network data input from the CAN

SYNC Outputs

  • Display unit CAN messages
    • Audio system commands
    • HVAC commands
  • Wired outputs to the ACM
    • Stereo (2 channel) audio
    • Monaural voice responses, including navigation guidance (if equipped)
    • Monaural phone call audio and phone ringtone
  • Commands to a USB or Bluetooth device
    • Outgoing call commands
    • Text-to-speech information for a phone
    • USB device file selection for playback

Remote SYNC Controls

The steering wheel switches remotely control some SYNC system functions. The steering wheel switch consists of multi-button switches that operate various SYNC functions.

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 APIM to control 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.

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

USB Mode

Connecting a portable media 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 SYNC-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.

The USB port(s) allow connection and playback of portable media devices and SYNC software updates.

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(s).

SYNC AppLink

The SYNC AppLink supports devices with customer-installed applications capable of outside control by voice command, the steering wheel switches, the radio control panel or the display unit (touchscreen only). 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.

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.

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 when this feature is enabled and a paired cellular phone is in the vehicle. 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 display unit.

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 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.

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.

SIRIUS™ Travel Link™ (if equipped)

SIRIUS™ Travel Link™ is a subscription-based service available on vehicles equipped with navigation. GPS data is required for certain features. When the subscription is active, the ESN of the ACM, with the VIN, is registered with SIRIUS.

SIRIUS™ Travel Link™ information includes traffic conditions, weather, fuel station locations and prices, and local entertainment information.

Traffic Announcement (vehicles equipped with a DAB radio)

The traffic announcement feature is a subscription-free based service available on vehicles equipped with navigation. GPS data is required for certain features.

This feature is not available in North America.

Android Auto™ or Apple CarPlay™

SYNC supports interaction with Android Auto™ and Apple CarPlay™ enabled phones connected by Bluetooth. This allows the user to access phone capabilities and control features via SYNC voice commands and switches. The features include:

  • making calls.
  • sending and listening to text messages.
  • selecting and playing music.
  • using the phone voice assistant.
  • using phone maps and navigation.

Android Auto™ and Apple CarPlay™ disable some SYNC features. Most Android Auto™ or Apple CarPlay™ features use mobile data.

SYNC Connect (if equipped)

NOTE: Depending on the notification settings, the vehicle may report a Deep Sleep Mode on supported mobile Apps. This occurs when battery voltage drops below a level necessary for correct vehicle operation or the vehicle has been inactive for a number of days.

The SYNC Connect system (when activated) provides remote connectivity through the FordPass mobile phone application. It can monitor certain vehicle systems and carry out vehicle functions such as:

  • reading the fuel level and odometer.
  • receiving remote alerts and notifications.
  • carrying out or scheduling remote starts (if enabled through the IPC).
  • using the vehicle locator.
  • vehicle lock/unlock control and vehicle lock/unlock status.

NOTE: If vehicle battery voltage falls below the minimum required or the vehicle has been inactive beyond a designated time limit, the TCU turns off until the next engine running event to preserve battery power. The connected mobile device App reports a deep sleep mode if notifications are turned on. Refer to the mobile device App information to set notifications and for a list of disabled features when the vehicle is in deep sleep mode.

The SYNC Connect system uses the TCU to communicate via the cellular network with a device running the SYNC Connect application. The TCU communicates with other vehicle modules over the CAN to obtain information or to carry out application commands, depending on the request.

The primary means of communication between the TCU and the cellular network uses cellular antennas integrated into the GPS/satellite radio antenna. Separate coaxial cables connect the cellular portion of the antenna to the TCU for the primary and secondary cellular inputs.

SYNC Connect data is transmitted via the cellular network to a server or cellular device with the SYNC Connect application installed. The data received via the cellular network from the device application is processed by the TCU, which can make vehicle system commands via the CAN.

Vehicle Wi-Fi Hotspot (if equipped)

The Wi-Fi hotspot feature allows up to 8 devices to connect to high speed internet access. The network name, password, enable/disable and other settings for the Wi-Fi Hotspot feature are accessed using the settings menu on the display unit (touchscreen).

The TCU provides the vehicle Wi-Fi access point.

The TCU communicates to the cellular network by two means. The primary connection is through the coaxial cable to the primary cellular antenna integrated into the roof mounted antenna. The secondary means is through the secondary cellular antenna cable to the secondary cellular antenna (located forward of the IPC).

MyKey™ Audio Feature

NOTE: Refer to the Owner Literature for additional details of the MyKey features.

MyKey use can affect audio system functions.

When a MyKey is in use and the MyKey volume limiter is enabled, the speed compensated volume feature is disabled.

When a MyKey is in use, the following MyKey audio effects are always present, regardless of administrator settings:

  • When the seatbelts are not buckled, the audio system mutes and a message informs the driver to buckle up to unmute the audio.
  • The satellite radio adult content channels are muted.

The following audio changes can be set by the MyKey administrator to occur when a MyKey is in use:

  • The emergency assistance (911 Assist) can be set to always on and cannot be disabled by the MyKey driver.
  • Audio volume can be limited in various circumstances, including turning off speed compensated volume or reducing volume at higher vehicle speeds. The display notifies the MyKey driver when volume is limited.
