2 Network Message Chart 2 of 20 6/28/16, 6:53 PM

3 A missing network message is indicated by a U-code DTC and can be the result of intermittent concerns such as damaged wiring or low battery voltage occurrences. Additionally, vehicle repair procedures such as module reprogramming can set these Diagnostic Trouble Codes (DTCs). When a missing message DTC (U-code) sets, it is important to look for symptoms present in the audio system and throughout the vehicle, and to review the complete message list to determine which other modules rely on the same message. Refer to: Communications Network (418-00). See CAN Multiplex Messages. When the other modules have been identified, run the self-test for those modules. If the same message is missing from those modules, the identical, or similar lost communication Diagnostic Trouble Codes (DTCs) may be set in those modules. Confirmation of missing messages common to multiple modules can indicate that the originating module is the source of the concern, or that the communication network may be at fault. It is very important to understand the following: Where the input originates All of the information necessary for a feature to operate Which module(s) receive(s) the input or command message Which module controls the output of the feature If the module that receives the input controls the output of the feature, or whether it outputs a message over the CAN to another module.

Network Input Messages - RCM Broadcast Message ecall confirmation APIM Used to confirm the configuration of the 911 Assist feature, and to confirm the status of the 911 Assist phone call. Accessory Delay Feature The accessory delay feature is a BCM-controlled software function that 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. AM/ FM Radio The AM/ FM on-glass antenna grid (coupe) or fender-mounted antenna (convertible) receives analog radio waves and sends them through the AM/ FM antenna amplifier (coupe) and AM/ FM antenna coaxial cable to the ACM. The radio waves are converted into fluctuating AC voltage and sent as left and right analog audio signals to the audio DSP module. For vehicles without Shaker, the audio DSP module processes the audio signals and sends them to the speakers as fluctuating AC voltage. For vehicles with Shaker, the audio DSP 7 of 20 6/28/16, 6:53 PM

8 module processes the audio signals and sends them to the speakers and subwoofer amplifier as fluctuating AC voltage. The subwoofer amplifier processes the audio signals and sends them to the subwoofer speaker as fluctuating AC voltage. ANC - 2.3L ANC is an audio system feature that eliminates a certain range of low frequency engine noise within the passenger compartment typically induced under wide open throttle or heavy part-throttle conditions. The system uses two (coupe) or three (convertible) microphones, a DACMC (contained within the ACM), and the audio system speakers. The DACMC determines the noise frequency to be canceled based upon engine rotation speed data, engine torque data, and accelerator pedal position data from the PCM, as well as microphone input signals. 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 audio DSP module as fluctuating AC voltage. The audio DSP module sends the signal to the LHF and RHF door woofer speakers, and right and left parcel shelf full-range (without Shaker) or coaxial (with Shaker) speakers (coupe) or RHR and LHR quarter panel full-range (without Shaker) or coaxial (with Shaker) speakers (convertible) as fluctuating AC voltage. APIM Programming The APIM requires specific programming procedures for correct operation when it is replaced, when upgrades are available and requested, or when directed by a TSB, FSA, SSM, or Electronic Field Communication (EFC) to resolve SYNC performance concerns. For more information, Refer to: SYNC [APIM] Programming (415-00B Information and Entertainment System - General Information - Vehicles With: Touchscreen Display, General Procedures). Audio Extended Play This software feature allows the audio system to operate with the ignition OFF, regardless of door latch position. When the power button on the FCIM is pressed, audio system functionality is enabled and remains active for a period of 30 minutes. Audio extended play will not function if the battery load shed is active. To turn the audio system off, press the FCIM power button. 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 FDIM 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 8 of 20 6/28/16, 6:53 PM

9 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 confirmed 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 Bluetoothenabled 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-deviceworks-with-sync.html or es.owner.ford.com/how-tos/sync-technology/all/phone-setup/how-your-deviceworks-with-sync.html For more information, refer to Bluetooth in the Owner's Literature. CD Mode When a CD is inserted into the ACM through the CD slot, audio files from the CD can be played through the vehicle speakers. Functions such as volume, seek, fast forward, pause, etc. can be controlled with the vehicle audio controls. When playing media files stored on a CD, the ACM only plays supported file types that are contained on a properly formatted disc. In addition to audio information (track length, track number, etc.), metadata (information such as artist, album title, and song title) may be sent over the CAN from the ACM to the APIM to be displayed on the FDIM. For more information, refer to CD and CD Player Information in the Owner's Literature. Chimes Various vehicle systems send chime requests over the CAN to the. The following are determined as the 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 9 of 20 6/28/16, 6:53 PM

10 The sends the processed requests over the CAN to the ACM. The ACM outputs the left and right analog chime tones to the audio DSP module over dedicated chimes circuits as fluctuating AC voltage. The audio DSP module outputs the chime tones to the appropriate audio system speakers as fluctuating AC voltage. For more information, Refer to: Warning Chimes - Overview ( Instrumentation, Message Center and Warning Chimes, Description and Operation). For even more information, Refer to: Warning Chimes - System Operation and Component Description ( Instrumentation, Message Center and Warning Chimes, Description and Operation). Compass The GPS antenna integral to the satellite radio antenna is used to acquire the compass heading. The compass heading is sent through the satellite radio/ GPS coaxial cable, satellite radio/ GPS splitter, and GPS coaxial cable to the APIM. The APIM uses this data in addition to wheel speed and wheel rotation direction CAN messages from the ABS module to calculate and provide accurate vehicle tracking. The APIM processes the data and transmits it though the LVDS (Low Voltage Differential Signaling) cable to be displayed on the FDIM. In the event that the GPS fix or signal is temporarily lost, the APIM will continue to use the CAN messages from the ABS module as well as information from the internal gyroscope and accelerometer to provide accurate vehicle tracking. DSP The Shaker audio system (if equipped) provides theater quality sound in the vehicle. Audio signals are sent from the ACM and APIM to the audio DSP module. The audio DSP module processes the audio signals and sends them to the speakers. The audio DSP module determines the correct audio environment based on the audio signals and network messages it receives from other audio system modules. These messages include information such as fade/balance and speed compensated volume settings. ESE - 2.3L And 5.2L ESE is an audio system feature that enhances certain engine tones typically induced under wide open throttle or heavy part-throttle conditions. The system uses a DACMC (contained within the ACM) and the audio system speakers. The DACMC determines the engine tone to enhance based upon engine rotation speed data, engine torque data, and accelerator pedal position data from the PCM. The data from the PCM is processed and converted into an analog audio signal, transmitted to the DACMC internal tone generator, and output by the ACM to the audio DSP module as fluctuating AC voltage. The audio DSP module sends the signal to the LHF and RHF door midwoofer (without Shaker) or woofer (with Shaker) speakers and right and left parcel shelf (with 5.2L) speakers as fluctuating AC voltage. HD Radio - With Shaker HD Radio is a subscription-free service. HD Radio technology allows an AM or FM radio station to duplicate their traditional analog channel with a matching digital channel. Some FM radio stations subdivide the digital output signal into multiple channels that are not duplicates of the analog channel. These extra multicast channels vary in availability and are called HD2, HD3 and HD4 channels. 10 of 20 6/28/16, 6:53 PM

11 The AM/ FM on-glass antenna grid (coupe) or fender-mounted antenna (convertible) receives radio waves containing metadata (information such as station call letters, artist, album title, song title, and genre) and digital HD Radio audio. The radio waves are sent through the AM/ FM antenna amplifier (coupe) and AM/ FM antenna coaxial cable to the HD Radio receiver built into the ACM. The metadata is separated from the audio. The metadata is sent to the APIM to be displayed on the FDIM, and the audio is converted into fluctuating AC voltage and sent as left and right analog audio signals to the audio DSP module. For vehicles without Shaker, the audio DSP module processes the audio signals and sends them to the speakers as fluctuating AC voltage. For vehicles with Shaker, the audio DSP module processes the audio signals and sends them to the speakers and subwoofer amplifier as fluctuating AC voltage. The subwoofer amplifier processes the audio signals and sends them to the subwoofer speaker as fluctuating AC voltage. For more information, refer to HD Radio in the Owner's Literature. MyKey Audio Operation The following MyKey features are always enabled when a MyKey is in use, and are not configurable on/off with an administrator key: Belt-Minder : The audio system is muted, and MyKey Buckle Up to Unmute Audio" is displayed in the information display until the safety belts are buckled. Satellite Radio: Adult content channels are blocked by being muted. The following MyKey features are configurable with an administrator key: 911 Assist : If the administrator has selected "Always On" in the MyKey menu, 911 Assist is enabled and cannot be disabled. Do Not Disturb: If the administrator has selected "Always On" in the MyKey menu, the Do Not Disturb feature is enabled and cannot be disabled. Speed Compensated Volume: If the administrator has enabled the Volume Limiter feature, the speed compensated volume feature will be disabled. Speed Limiter: If the administrator has enabled the Speed Limiter feature, the audio volume level is temporarily reduced so the top speed alert chime can be heard when the preselected top vehicle speed is reached. Speed Minder: If the administrator has enabled the Speed Minder feature, the audio volume level is temporarily reduced so the speed alert chime can be heard when the preselected Speed Minder vehicle speed is exceeded. Volume Limiter: If the administrator has enabled the Volume Limiter feature, the audio system volume is limited to 46.6%. In an attempt to exceed the limited volume, MyKey Volume Limited is displayed on the information display. For more information, refer to MyKey in the Owner's Literature. Navigation - If Equipped The navigation system guides the customer to a pre-entered destination. The navigation display is shown on the FDIM. Map data is stored in the APIM. The GPS antenna integral to the AM/ FM/satellite radio antenna receives GPS data and sends it through the satellite radio/ GPS coaxial cable, satellite radio/ GPS splitter, and GPS coaxial cable to the APIM. The APIM uses this data in addition to wheel speed and wheel rotation direction CAN messages from the ABS module to calculate route information and provide accurate navigation tracking. The APIM processes the data and transmits it though the LVDS (Low Voltage Differential Signaling) 11 of 20 6/28/16, 6:53 PM

12 cable to be displayed on the FDIM. In the event that the GPS fix or signal is temporarily lost, the APIM will continue to use the CAN messages from the ABS module as well as information from the internal gyroscope and accelerometer to provide accurate vehicle tracking. The voice recognition system allows the customer to interface with the system without using the FDIM. A microphone located in the overhead console provides a direct input to the APIM. For more information, refer to Navigation in the Owner's Literature. RDS RDS allows metadata (information such as station call letters, artist, song title, and genre) to be contained within FM radio waves. If the RDS feature is turned on, a PTY (Program Type) can be chosen. Once the customer has chosen a single PTY such as Sports, Rock, Religious Music, or Weather, the SEEK or SCAN button is pressed, and the ACM only tunes channels within the selected category. If a channel within the selected category is not found, the ACM will continually seek or scan. Satellite Radio Satellite radio is a subscription-based service. When a satellite radio subscription is activated, the ESN of the satellite radio receiver built into the ACM is associated with the VIN. The SIRIUS 12-digit ESN can be obtained by tuning to channel 0, accessing AHU Part Numbers in Bezel Diagnostics, or by referencing the label attached to the ACM. The roof-mounted (coupe) or luggage compartment lid-mounted (convertible) satellite radio antenna receives signals containing metadata (information such as station name, artist, album title, song title, and genre) and digital satellite radio audio. These signals are sent through the satellite radio/gps coaxial cable, satellite radio/ GPS splitter, and satellite radio antenna coaxial cable to the satellite radio receiver built into the ACM. The metadata is separated from the audio. The metadata is sent to be displayed on the FDIM, and the audio is converted into fluctuating AC voltage and sent as left and right analog audio signals to the audio DSP module. For vehicles without Shaker, the audio DSP module processes the audio signals and sends them to the speakers as fluctuating AC voltage. For vehicles with Shaker, the audio DSP module processes the audio signals and sends them to the speakers and subwoofer amplifier as fluctuating AC voltage. The subwoofer amplifier processes the audio signals and sends them to the subwoofer speaker as fluctuating AC voltage. SIRIUS Travel Link - If Equipped With Navigation SIRIUS Travel Link is a subscription-based service, and requires a separate subscription from the satellite radio. When a SIRIUS Travel Link subscription is activated, the ESN of the satellite radio receiver built into the ACM is associated with the VIN and registered in the SIRIUS database. The SIRIUS 12-digit ESN can be obtained by tuning to channel 0, accessing AHU Part Numbers in Bezel Diagnostics, or by referencing the label attached to the ACM. SIRIUS Travel Link allows the customer to receive information for: Fuel Prices (stations, fuel type) Movie Listings (theaters, movie titles, ratings, start and run times) Ski Conditions (resorts, lodging, conditions) Sports (in-game and final scores, weekly schedules, headlines) Traffic (traffic flow, accidents, construction, road closings) Weather (current weather, forecasts, radar images) 12 of 20 6/28/16, 6:53 PM

13 The SIRIUS Travel Link feature requires the use of an APIM equipped with navigation. The satellite radio antenna receives digital signals containing Travel Link data. The time intervals that the antenna receives the signals for each Travel Link category to update the data vary depending on the category. These signals are sent through the satellite radio antenna coaxial cable to the satellite radio receiver built into the ACM. The satellite receiver decrypts the data and the ACM sends it to the APIM through the SDL circuits. Certain date-dependent features (such as sports schedules and scores, movie times, and the 5-day weather forecast) require the use of GPS data for accuracy. The APIM processes the data from the ACM (together with GPS data obtained from the GPS coaxial cable for date-dependent features that require the use of GPS data for accuracy) and sends it to the FDIM to be displayed. For more information, refer to Sirius Travel Link in the Owner's Literature. Speed Compensated Volume The audio DSP module compensates for wind and road noise by adjusting the audio system volume based on the VSS signal and customer-defined setting. When a MyKey is in use and the MyKey Volume Limiter is enabled, the speed compensated volume is disabled. Steering Wheel Switch Functions The RH steering wheel switches consist of an upper 5-way switch, and a lower 4-way switch. The upper 5-way steering wheel switch operates the volume +/-, seek +/-, and the audio mode. The lower 4-way steering wheel switch operates the voice, send/receive call, end call, and mute functions. SYNC AppLink SYNC AppLink allows Applications installed on the customer s device to be controlled using the steering wheel switches, FCIM, and/or FDIM. All devices must be paired with the SYNC system via Bluetooth, and Apple devices must also be connected to a USB port. Data is transmitted back and forth between the customer s device and the APIM through Bluetooth, or through the USB port with Apple devices. For more information, refer to AppLink in the Owner's Literature. SYNC System The SYNC system uses Bluetooth, USB, FDIM, GPS, microphone, and CAN message APIM inputs to control the entertainment system, phone, climate control system, ambient lighting system, and navigation system (if equipped). The SYNC system provides the following abilities: 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) in order to play audio files Initiate an emergency assistance call (911 Assist ) when the airbags deploy (for more information, 13 of 20 6/28/16, 6:53 PM

14 refer to 911 Assist in the Owner's Literature) All SYNC system features are not available with every phone/device. To determine if the APIM supports a particular phone, tablet, or media player, or feature of one of those devices, review the device compatibility list. Refer to: owner.ford.com/how-tos/sync-technology/all/phone-setup/how-your-device-workswith-sync.html or es.owner.ford.com/how-tos/sync-technology/all/phone-setup/how-your-device-workswith-sync.html The customer can update the CIP by using a USB flash drive or a Wi-Fi connection not requiring a browser sign in or two-step security validation. The update is approximately 600 MB. If the APIM 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 APIM is allowed to download the update for up to 150 minutes in a month for a maximum of 30 minutes at a time. If the APIM is connected to a mobile Wi-Fi hotspot (network) for automatic updates, the update download can occur with the ignition in ON/RUN and the vehicle stationary or in motion. Once the update download and installation is complete, an ignition cycle must occur before the update becomes active. For more information, refer to Updating Your System in the Owner's Literature. For more information on the SYNC system, refer to SYNC in the Owner's Literature. USB Mode When a portable media device, such as an ipod with its available cable or portable mass storage such as a USB flash drive, is connected to the vehicle audio system through the USB ports, audio from the device can be played through the vehicle speakers. Functions such as volume, seek, fast forward, pause, etc. can be controlled with the vehicle s audio controls. When playing media files stored on a mass storage device such as a USB flash drive, the SYNC system only plays supported file types that do not have DRM protection, and are contained on a properly formatted device. For more information, refer to Supported Media Players, Formats and Metadata Information in the Owner's Literature. In addition to audio information (track length, track number, etc.), metadata (information such as artist, album title, song title, and genre) may also be sent to the APIM from a device connected to the USB ports. The APIM uses the metadata to create indexes that can be used to sort for particular music based on the customer s preferences. Not all USB devices can send metadata to the APIM. When a new media device is connected to the SYNC system, the APIM automatically indexes the information. This may take several minutes depending on the amount of data on the device, and is considered normal operation. When a device that was previously connected to the SYNC system is reconnected, the APIM updates the index rather than creating a new one. This reduces the time needed to index the device. Voice Recognition Voice recognition allows certain phone, navigation system (if equipped), audio system, and climate control system functions to be controlled with voice commands to reduce or eliminate the need to interact with the FCIM, FDIM, and/or device while driving. When the voice steering wheel switch is pressed, an audible prompt originating from the APIM is heard from the speakers. Based on the customer s setting, audible prompts will either be a voice or a simple tone. 14 of 20 6/28/16, 6:53 PM

15 When interaction mode is set to standard, detailed voice guidance is provided. When interaction mode is set to advanced, most prompts are tones only, and minimal voice guidance is provided. The microphone receives the voice commands and sends them to the APIM. For more information, refer to voice recognition in the Owner's Literature. ACM Component Description The ACM can be operated with the ignition in RUN, ACC, or OFF. The ACM receives radio waves containing audio from the antenna coaxial cables and converts them into fluctuating AC voltage. The ACM receives stereo and mono audio signals from the APIM in the form of fluctuating AC voltage. The ACM processes all inputs, and depending on the input received, sends stereo or mono analog audio signals to the audio DSP module. For vehicles without Shaker, the audio DSP module processes the audio signals and sends them to the speakers as fluctuating AC voltage. For vehicles with Shaker, the audio DSP module processes the audio signals and sends them to the speakers and subwoofer amplifier as fluctuating AC voltage. The subwoofer amplifier processes the audio signals and sends them to the subwoofer speaker as fluctuating AC voltage. The ACM receives radio waves containing satellite radio and HD Radio (with Shaker) data through the antenna coaxial cables. The data is sent to be displayed on the FDIM. The ACM contains the CD player. The ACM sends data to the APIM through the SDL circuits for the SIRIUS Travel Link features for vehicles with navigation. The ACM contains the DACMC for vehicles with the 2.3L or 5.2L. The ACM and DACMC require separate PMI procedures when the ACM is replaced. AM/ FM Antenna Amplifier - Coupe The AM/ FM antenna amplifier receives AM/ FM radio waves from the on-glass antenna grid. The AM/ FM antenna amplifier is powered by the ACM and amplifies AM audio signals to improve reception. The AM/ FM radio waves are sent through the AM/ FM antenna coaxial cable to the ACM. ANC Microphones - 2.3L For a coupe, two ANC microphones (overhead console-mounted and center rear headliner-mounted) measure the amplitude and phase of the engine noise inside the passenger compartment. For a convertible, three ANC microphones (overhead console-mounted, RHR quarter panel, and LHR quarter panel) measure the amplitude and phase of the engine noise inside the passenger compartment. The monitored sounds are converted into analog signals by the microphones and sent to the DACMC (contained within the ACM). Antenna The AM/ FM radio uses the on-glass (coupe) AM/ FM antenna grid or RHR fender-mounted (convertible) AM/ FM antenna to receive analog radio waves. The radio waves are sent through the AM/ FM antenna amplifier (coupe) or amplifier integrated into the antenna base (convertible) and AM/ FM antenna coaxial cable to the ACM. The ACM transmits these radio waves to the audio DSP module where they are further amplified. 15 of 20 6/28/16, 6:53 PM

16 To compensate for AM signal strength loss as the radio waves are transmitted from the antenna to the ACM, battery voltage is applied to the antenna amplifier (coupe) or amplifier integrated into the antenna base (convertible) to boost the AM radio signal. This allows the AM radio waves entering the ACM to be approximately the same strength as they were before amplification at the antenna. For vehicles with Shaker, the HD Radio uses the on-glass (coupe) AM/ FM antenna grid or RHR fendermounted (convertible) AM/ FM antenna to receive radio waves containing digital audio and data. The radio waves are sent to the AM/ FM antenna amplifier (coupe) or amplifier integrated into the antenna base (convertible) where the radio waves containing digital audio are amplified to improve reception. The amplified radio waves containing audio and the radio waves containing data are sent through the AM/ FM antenna coaxial cable to the HD Radio receiver built into the ACM. The ACM transmits these radio waves to the audio DSP module where the radio waves containing digital audio are further amplified, and the radio waves containing data are sent to be displayed on the FDIM. The satellite radio uses the roof-mounted (coupe) or luggage compartment lid-mounted (convertible) satellite radio/gps antenna to receive signals containing digital audio and data. These signals are sent through the satellite radio/ GPS coaxial cable, satellite radio/ GPS splitter, and satellite radio antenna coaxial cable to the satellite radio receiver built into the ACM. The roof-mounted (coupe) or luggage compartment lid-mounted (convertible) satellite radio/gps antenna contains a GPS antenna circuit board that receives radio waves containing GPS data. The data is sent through the satellite radio/ GPS coaxial cable, satellite radio/ GPS splitter, and GPS coaxial cable to the APIM. APIM The APIM can be operated with the ignition in RUN, ACC, or OFF. The APIM receives stereo and mono inputs. Stereo inputs include audio from the USB ports, connected Bluetooth-enabled media device, and outside device during a phone call. The mono input includes signals from the SYNC microphone. The APIM sends stereo and mono audio signals to the ACM as fluctuating AC voltage. Stereo outputs include audio from the USB ports, connected Bluetooth-enabled media device, ringback tone, outside device during a phone call, voice or tone prompts initiated from the voice steering wheel switch, and instructions or information spoken by the SYNC system when initiated from the voice steering wheel switch. Mono outputs include audio from the TTS feature, incoming call ringtone, instructions or information spoken by the SYNC system when initiated from the FDIM, and navigation route guidance voice or tone prompts (if equipped with navigation). For vehicles with navigation, the APIM receives SIRIUS Travel Link data from the ACM through the SDL circuits. This data is processed and sent to be displayed on the FDIM. The TTS feature allows the customer to hear information through the audio system speakers so it does not have to be read from the FDIM and/or device while driving. Examples include incoming text message sender information, text messages, and metadata from audio being played via USB or Bluetooth. The APIM consists of two internal modules: the CIP and the VIP. The modules are not replaceable individually, but can be programmed independently if required. The CIP interfaces with all of the customer inputs to the APIM. It contains an analog-to-digital-to-analog converter, as well as the Bluetooth/Wi-Fi chipset. 16 of 20 6/28/16, 6:53 PM

17 The VIP provides an interface between the CIP and the vehicle inputs. Its main functions are controlling the APIM power management and translating inbound and outbound CAN signals. The APIM provides the FDIM with power and ground through the LVDS (Low Voltage Differential Signaling) cable. The APIM receives GPS data through the GPS coaxial cable. The data is used for the navigation system (if equipped) and SIRIUS Travel Link date/time-dependent features such as sports schedules and scores, movie times, and the 5-day weather forecast. The APIM also uses this data to identify the vehicle s location in the event of a collision and to display the compass heading on the FDIM. The APIM requires programming when it is replaced. Audio DSP The audio DSP module can be operated with the ignition in RUN, ACC, or OFF. The audio DSP module enhances the input audio signal sound quality from the ACM. The ACM outputs voltage through the enable circuit to enable the audio DSP module amplifier. When the ACM removes voltage from this circuit, the audio will be muted. When the ACM applies the correct amount of voltage to this circuit, the audio will be unmuted. In the event of an amplifier overload, the audio DSP module reduces audio levels on the left and right audio output channels to prevent clipping and speaker damage. The audio DSP module receives stereo and mono audio signals from the ACM in the form of fluctuating AC voltage. The audio DSP module processes and amplifies these inputs and depending on the input received, sends stereo or mono analog audio signals to the speakers and subwoofer amplifier as fluctuating AC voltage. When the engine is running, the audio DSP module receives the engine noise cancellation frequency signal (2.3L) and ESE frequency signal (2.3L and 5.2L) from the ACM in the form of fluctuating AC voltage. The audio DSP module sends the engine noise cancellation frequency signal to the LHF and RHF door woofer speakers, and left and right parcel shelf full-range (without Shaker) or coaxial (with Shaker) speakers (coupe) or RHR and LHR quarter panel full-range (without Shaker) or coaxial (with Shaker) speakers (convertible) as fluctuating AC voltage. The ESE signal is sent to the LHF and RHF door woofer speakers and right and left parcel shelf (with 5.2L) speakers as fluctuating AC voltage. When the engine is running and the audio system is in use, the audio DSP module output to the LHF and RHF door woofer speakers contains a mixture of the engine noise cancellation and ESE frequency with the audio signals from the ACM. The output to the right and left parcel shelf full-range (without Shaker) or coaxial (with Shaker) speakers (coupe) or RHR and LHR quarter panel full-range (without Shaker) or coaxial (with Shaker) speakers (convertible) contains a mixture of the engine noise cancellation and ESE frequency with the audio signals from the ACM. The audio DSP module requires PMI when it is replaced. DACMC - 2.3L Or 5.2L The DACMC ANC and ESE functions only operate while the engine is running, and the luggage compartment lid and all doors are closed. The DACMC is a digital signal processor that consists of an internal analog/digital converter and tone 17 of 20 6/28/16, 6:53 PM

18 generator. For ANC, the DACMC uses engine rotation speed data, engine torque data, accelerator pedal position data, and ANC microphone input signals to calculate the targeted frequency needed to cancel engine noise within the passenger compartment. For ESE, the DACMC uses engine rotation speed data, engine torque data, and accelerator pedal position data from the PCM to calculate the targeted frequency needed to enhance engine noise within the passenger compartment. The DACMC engine noise cancellation signals are output by the ACM to the audio DSP module as fluctuating AC voltage. The audio DSP module sends the signal to the LHF and RHF door woofer speakers, and right and left parcel shelf full-range (without Shaker) or coaxial (with Shaker) speakers (coupe) or RHR and LHR quarter panel full-range (without Shaker) or coaxial (with Shaker) speakers (convertible) as fluctuating AC voltage. The DACMC ESE frequency signals are output by the ACM to the audio DSP module as fluctuating AC voltage. The audio DSP module sends the signal to the LHF and RHF door woofer and right and left parcel shelf (with 5.2L) speakers as fluctuating AC voltage. The DACMC is contained within the ACM. The DACMC and ACM require separate PMI procedures when the ACM is replaced. FCIM The FCIM audio functions can be operated with the ignition in RUN, ACC, or OFF. The FCIM audio system buttons provide one of the methods through which the customer interacts with the infotainment system. The FCIM is separate from the ACM. The FCIM requires PMI when it is replaced. FDIM The FDIM can be operated with the ignition in RUN, ACC, or OFF. The capacitive touch FDIM provides one of the methods through which the customer interacts with the infotainment system. For more information, refer to Using the Touchscreen in the Owner's Literature. The FDIM is attached to the APIM. As the FDIM does not communicate on the CAN, the APIM acts as the proxy for all FDIM inputs and outputs requiring CAN communication. Communication between the FDIM (including FDIM customer inputs) and APIM is accomplished via the LVDS (Low Voltage Differential Signaling) cable. The FDIM power and ground are provided by the APIM through this cable as well. LVDS (Low Voltage Differential Signaling) Cable The four circuit shielded LVDS (Low Voltage Differential Signaling) cable provides power and ground from the APIM to the FDIM and is also the means by which data is transmitted from the APIM to the FDIM and from the FDIM to the APIM. Noise Suppression Equipment The radio frequency suppression equipment reduces interference transmitted through the speakers by the engine, ignition, and electrical systems. When installing any new radio suppression equipment components, 18 of 20 6/28/16, 6:53 PM

19 make sure that a good contact is made at all connections. Remote USB Port/Cable The remote USB port/cable sends data to the USB hub. The non-illuminated USB port is part of the USB cable, and cannot be replaced separately. The remote USB port/cable is powered by the USB hub (which receives power through circuits from the APIM), and can be used to power and/or charge a device if the device supports this feature and does not have a power consumption requirement of more than approximately 5V and 2.5A (about 13 watts). Steering Wheel Switches The RH upper and lower steering wheel switches contain series of resistors. Each steering wheel switch function corresponds with a specific resistance value within the switch. The SCCM sends a 5-volt reference voltage to the RH upper and lower steering wheel switches on the input circuit. When a switch is pressed, the voltage is routed through the corresponding resistor(s), through the return circuit, and then to ground through the SCCM. The SCCM monitors the resultant voltage drop to determine which switch was pressed. The voltage drop varies depending upon the resistance of the specific switch pressed. The RH upper steering wheel switch inputs are sent as network messages from the SCCM to the ACM to control audio functions. The RH lower steering wheel switch inputs are sent as network messages from the SCCM to the APIM to control SYNC functions, or to the ACM to control audio functions. Subwoofer Amplifier - With Shaker The subwoofer amplifier can be operated with the ignition in RUN, ACC, or OFF. The subwoofer amplifier, speaker, and enclosure are serviced as an assembly. The audio DSP module outputs voltage through the enable circuit to enable the subwoofer amplifier. The audio DSP module also uses this circuit to detect an amplifier overload condition. In the event of an amplifier overload, the subwoofer amplifier modifies the voltage signal from the audio DSP module to increase the voltage on the enable circuit to a higher level than provided by the audio DSP module. This higher voltage level causes the audio DSP module to momentarily reduce the audio levels on the audio output channels to the subwoofer amplifier to prevent clipping and subwoofer speaker damage. The subwoofer amplifier receives audio signals from the audio DSP module in the form of fluctuating AC voltage. The subwoofer amplifier processes and amplifies these inputs and sends analog audio signals to the subwoofer speaker as fluctuating AC voltage. SYNC Microphone The SYNC microphone is powered by the APIM. The SYNC microphone receives SYNC system voice commands and outgoing audio during a phone call. The monitored sounds are converted into analog signals by the microphone and sent to the APIM as fluctuating AC voltage. 19 of 20 6/28/16, 6:53 PM

20 USB Hub The USB hub contains one illuminated USB port. The USB port allows audio from portable media devices to play through the vehicle speakers. The USB hub is powered by circuits carrying battery voltage from the APIM. The APIM outputs approximately 5V on the USB cable to power the USB cable data communication circuits. The USB ports can be used to power and/or charge a device if the device supports this feature and does not have a power consumption requirement of more than approximately 5V and 2.5A (about 13 watts). Data received from the remote USB port/cable and from the USB hub USB port is sent to the APIM through the USB cable. Copyright 2016 Ford Motor Company 20 of 20 6/28/16, 6:53 PM
