Principles of Operation

AM/FM Antenna

The AM/FM antenna is a fixed mast antenna mounted on the exterior of the vehicle. The antenna receives both AM and FM radio waves. The audio signals are then sent to the ACM through the antenna cables.

Audio DSP Amplifier

The 8 channel non-networked audio DSP amplifier is found on Shaker/Shaker Pro-equipped vehicles. Audio signals are sent from the ACM to the audio DSP amplifier. These signals are amplified and sent to the 8-inch (203 mm) subwoofer speaker in each door , the 2 speaker assembly found in each door, and the 2 rear package tray (coupe) or 2 quarter panel (convertible) speakers.

Audio Front Control Module (ACM)

The Audio Front Control Module (ACM) operates with the ignition in RUN or ACC. The accessory delay feature allows the audio system to be operated for a preset period of time after the key is turned off and a door has not been opened. The ACM sends AC voltage audio signals to the speakers or to the amplifiers, depending on vehicle configuration. The ACM produces its own DTCs, which are communicated to the diagnostic scan tool through the Medium Speed Controller Area Network (MS-CAN). The enable/clip circuit is used to turn on the audio DSP amplifier or subwoofer amplifier, depending on vehicle configuration, and to monitor an overload condition of the amplifiers. In the event of an overload, the ACM clips the audio output signal to the amplifier (heard as distortion).

Audio Input Jack

The audio input jack allows for a portable MP3 player to be connected to the vehicle audio system. When a portable MP3 player is connected, audio from the MP3 player can be played through the vehicle speakers.

Audio Signals

Stereo signals contain left and right channel information, and are used for most audio signals.

A mono signal is used for the microphone input to the APIM . The mono signal is also used for the voice prompts, the TTS feature, ringtones, and any audio received through a connected mobile phone. These audio signals are output from the APIM to the ACM . The mono and stereo outputs from the APIM utilize separate circuits.

A digital signal is used to transmit data from a media device connected through the USB port to the APIM . The APIM then converts the signal to analog and relays the signal to the ACM .

A wireless signal is used to broadcast audio signals from a Bluetooth device to the APIM . As with a digital signal sent through the USB port, the APIM converts the wireless audio signal to analog and relays it to the ACM .

Front Controls Interface Module (FCIM)

The Front Controls Interface Module (FCIM) acts as a customer interface with the audio system and the climate control system. When a switch is pressed, a message is broadcast over the MS-CAN . When a climate control switch is pressed, the HVAC module sends a message back to the FCIM to illuminate the correct switches to indicate the status of the climate control.

Front Display Interface Module (FDIM) (Without Navigation)

The Front Display Interface Module (FDIM) receives MS-CAN messages for all of its displays, which include:

Audio information
Climate control fan speed and temperature setting
Outside air temperature
Compass heading

Front Display Interface Module (FDIM) (With Navigation)

The FDIM does not communicate on the CAN and is hardwired to the ACM . When the touchscreen is pressed, a signal is sent to the ACM , which acts on the signal by changing either the audio setting or by broadcasting a message via the MS-CAN to the module controlling the function that was selected. The audio system, navigation, and climate control video feed to the FDIM is provided by the ACM . If equipped with a rear view camera, the video feed for the camera is provided directly by the rear view camera.

GPS Antenna

The GPS antenna is integral to the satellite radio antenna and is only present on vehicles with navigation. The location signals are sent to the ACM via a coaxial cable. A GPS / SDARS antenna splitter is used to provide separate satellite radio and Global Positioning System (GPS) inputs to the ACM .

Global Positioning System Module (GPSM)

The Global Positioning System Module (GPSM) provides vehicle location for real-time traffic reports and re-routing, and for identifying vehicle location in the event of a collision. The vehicle location information is broadcast to the APIM over the MS-CAN . The GPSM is only present on vehicles with SYNC® and without navigation.

Jukebox Feature (With Navigation)

The ACM contains a 10 gigabyte on-board hard-drive that is capable of storing music from a CD. Music can be loaded into the ACM jukebox by inserting a non-MP3 CD, and following the on-screen instructions. If the ACM is replaced, the music contained on the hard-drive cannot be retained. For more information about the Jukebox feature, REFER to the Owner's Literature.

Luggage Compartment Subwoofer Amplifier

The 4 channel non-networked luggage compartment subwoofer amplifier is found on Shaker Pro-equipped vehicles. Audio signals are sent from the ACM to the luggage compartment subwoofer amplifier. These signals are amplified and sent to the 10-inch (254 mm) luggage compartment subwoofer enclosure. Only 2 of the 4 channels are utilized, and are bridged for higher power output to the subwoofer.

Navigation System

The vehicle navigation system guides the user to a pre-entered destination. No navigation map DVD is needed, as the map guidance information is stored in the ACM hard-drive. The ACM calculates route information based on GPS data. The ACM also uses vehicle speed and transmission gear selected signals received through the MS-CAN to detect vehicle speed and direction, resulting in more accurate navigation tracking.

The navigation display is shown on the FDIM . Either the FDIM touchscreen or the buttons on the FCIM can be used to interact with the navigation system.

The compass heading is derived from the GPS antenna signal. There are no serviceable parts for the compass.

A voice recognition system allows the user to interface with the system without using the touchscreen. A microphone contained in the overhead console provides the voice recognition input and is shared with the SYNC® system.

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, make sure that a good contact is made at all connections.

Satellite Radio Antenna

The satellite radio antenna receives satellite radio signals. The signals are sent to the ACM through the satellite radio antenna cables. If equipped with the navigation system, an antenna splitter is used to provide separate satellite radio and Global Positioning System (GPS) inputs to the ACM .

Steering Wheel Switches

The steering wheel switches consist of a series of resistors. Each steering wheel switch function corresponds with a specific resistance value within the switch. When a switch is pressed, the ACM (or the APIM ) monitors the change in reference voltage to determine the requested function.

Subwoofers

The 8-inch (203 mm) subwoofer speakers utilized in the Shaker/Shaker Pro systems are located in the doors. Each subwoofer speaker is powered by 2 of the available 8 audio DSP amplifier channels. In addition to these subwoofer speakers, the Shaker Pro system includes an enclosure with one 10-inch (254 mm) dual voice coil subwoofer powered by a 4 channel amplifier.

SYNC® System

The SYNC® system allows interaction with several types of customer devices, including mobile phones and media devices. The APIM contains an on-board Bluetooth chipset which enables certain wireless devices to interact with the system.

The APIM consists of 2 internal modules: the Consumer Interface Processor (CIP) and the Vehicle Interface Processor (VIP). These modules are not replaceable individually, but can be flashed independently, if required.

The CIP interfaces with all of the inputs to the APIM . The CIP contains an analog-to-digital-to-analog converter, as well as the Bluetooth chipset. Any consumer-available application upgrades that are available are loaded directly to the CIP through the USB port.

The VIP provides an interface between the CIP and the vehicle. The main functions of the VIP are controlling the APIM power management and translating both inbound and outbound signals over the CAN .

The APIM can receive inputs from the following audio sources:

USB port
Audio input jack
Bluetooth

The USB port can be used for connecting a media device (such as an iPod®) with the device's available cable, or for directly plugging in a portable mass storage device (such as a "thumb drive"). When playing media files stored on a mass storage device, the SYNC® system only plays files that do not have Digital Rights Management (DRM) protection. The USB port can also be used for uploading vehicle application upgrades.

The USB port is powered by the APIM , so no external power source is needed to power a device plugged into the USB port if the device supports this feature.

The audio input jack can be used for connecting a media device (such as an iPod®) utilizing a 1/8-inch audio jack. When a device is connected through the audio input jack, only the speaker volume can be controlled by the ACM . All other functions (such as seek, fast forward, pause, etc.) must be carried out on the device itself.

The Bluetooth interface can accommodate both Bluetooth-enabled mobile phones and Bluetooth-enabled media devices. Any Bluetooth device used with the SYNC® system must first be paired with the system before it is operational.

Bluetooth is a secure, short-range radio frequency that allows devices to communicate wirelessly through radio waves. The operating range of a Bluetooth signal is a maximum of 9.75 m (32 ft).

Only one Bluetooth phone and one Bluetooth media device can be connected to the system at any one time. If an additional device of either type is paired with the system and made active, the APIM will disconnect any active connection and establish a connection with the new device.

It is important to understand that not all mobile phones will have the same level of features when interacting with the SYNC® system. For a list of compatible phones, refer to the SyncMyRide website.

In addition to audio information, metadata may also be sent to the APIM from a device plugged into the USB port. Metadata consists of such information as artist, album title, song title, and genre. The metadata is used by the APIM to create indexes that can be used to sort for particular music, based on customer preference. Not all USB devices can send metadata to the APIM ; also, no metadata is transferred when a device is connected through the audio input jack. 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), which reduces the amount of time needed to create the index.

The APIM receives both stereo and mono sound inputs and can also transmit both stereo and mono sound. The mono function is used to receive the microphone input, and to send sound to the ACM for voice prompts, the Text-To-Speech (TTS) feature, ringtones, and any audio received through a connected mobile phone. The TTS feature speaks information so that it does not have to be read from the display.

The APIM communicates on the MS-CAN and the High Speed Controller Area Network (HS-CAN). Communication with the diagnostic scan tool is established through the HS-CAN .

Voice Recognition [With Navigation (If Equipped), And With SYNC®]

When the audio system enters voice recognition mode, the ACM initially controls the voice recognition feature. The microphone is wired directly to the APIM , which relays the microphone input to the ACM through dedicated wiring. If the first command spoken is part of the ACM voice recognition set, the ACM retains control of the voice recognition and takes the appropriate action(s). If the first command spoken is part of the APIM voice recognition set, the ACM shuts off its own voice recognition and broadcasts a Controller Area Network (CAN) message to the APIM , which transfers the spoken voice command to the SYNC® system. The ACM controls the voice engine for the base audio, navigation, and climate control systems. The APIM controls the voice engine for the SYNC® system ( USB port, audio input jack, Bluetooth).

Network Communication

The following audio system modules communicate via the MS-CAN :

ACM (with and without navigation)
FCIM
FDIM (without navigation)
APIM
GPSM

There are numerous messages internal to the audio system. The functions of these messages include, but are not limited to:

Changing the audio source
Changing equalizer settings
Updating the FDIM display
Dialing phone numbers from the APIM (with SYNC®)

Pinpoint Tests

Pinpoint Test A: Poor Reception Or Continuous Seek Or Scan — AM/FM

Diagnostic Overview

Diagnostics in this manual assume a certain skill level and knowledge of Ford-specific diagnostic practices. Refer to Diagnostic Methods in Section 100-00 for information about these practices.

Refer to Wiring Diagrams Cell 130 , Audio System/Navigation for schematic and connector information.

Normal Operation

The AM/FM antenna receives AM and FM radio waves and transmits them to the Audio Front Control Module (ACM) through the AM/FM antenna cables. The ACM powers the AM/FM antenna in order to amplify the AM signal.

The noise suppression equipment reduces engine ignition and electrical systems interference transmitted through the speakers.

The RDS function allows the vehicle operator to choose which genre (category) of music to listen to. When the SCAN button is pressed, the ACM only stops at channels falling within the selected category. If no channel in the selected category is found, the ACM continues to scan without stopping. This may appear to be a reception issue, but it is actually due to the customer setting.

DTC B1A56:21 (Antenna: Signal Amplitude < minimum)="Audio Front Control Module" class="popup" onmouseover="this.className='popupnounderline';" onmouseout="this.className='popup';">ACM (without navigation) and ACM (with navigation) when the signal strength is less than the pre-configured threshold value during the self-test.

Diagnostics in this manual assume a certain skill level and knowledge of Ford-specific diagnostic practices. Refer to Diagnostic Methods in Section 100-00 for information about these practices.

Refer to Wiring Diagrams Cell 130 , Audio System/Navigation for schematic and connector information.

Normal Operation

Digital signals are received by the satellite radio antenna and sent to the Audio Front Control Module (ACM) through the satellite radio antenna cable. The satellite radio receiver is internal to the ACM .

When a satellite radio subscription is activated, the Electronic Serial Number (ESN) of the built-in satellite radio receiver is associated with the Vehicle Identification Number (VIN). As a result, the ACM cannot be swapped from one vehicle to another.

Obstructions to the antenna line of sight can affect reception, and is considered normal operation. Possible obstructions include hills, tall buildings, tunnels, and being parked inside a garage. Be sure the vehicle is in a clear area, free of obstructions, before testing satellite radio reception. When there is an open in the satellite radio antenna circuit, there is no satellite audio. The audio system display indicates a satellite radio antenna concern when the audio system is operated in satellite radio mode.

Pinpoint Test D: Loud Popping Sound When Cycling The Ignition Switch

Diagnostic Overview

Diagnostics in this manual assume a certain skill level and knowledge of Ford-specific diagnostic practices. Refer to Diagnostic Methods in Section 100-00 for information about these practices.

Refer to Wiring Diagrams Cell 130 , Audio System/Navigation for schematic and connector information.

Normal Operation

Voltage is sent through the start input circuit to the Audio Front Control Module (ACM) with the ignition in START. Upon receiving this signal, the ACM mutes all speaker outputs to eliminate the possibility of voltage spikes producing a popping noise through the speakers.

The ACM disables the audio DSP amplifier (Shaker/Shaker Pro) and subwoofer amplifier (Shaker Pro) with the ignition in START by keeping the enable circuit voltages below 0.4 volt.

If there is a short to voltage on any of the enable circuits, distortion is heard from the speakers whenever the ACM is powered on, and that should be the primary concern addressed. If the speakers have distorted sound, GO to Symptom Chart - Sound Quality .

When the ACM is powered on, normal operating voltage for the amplifier enable circuit is between 3.8 and 6.7 volts.

Pinpoint Test H: No Sound From The Luggage Compartment Subwoofer

Diagnostic Overview

Diagnostics in this manual assume a certain skill level and knowledge of Ford-specific diagnostic practices. Refer to Diagnostic Methods in Section 100-00 for information about these practices.

Refer to Wiring Diagrams Cell 130 , Audio System/Navigation for schematic and connector information.

Normal Operation

The luggage compartment subwoofer is powered by its exclusive amplifier.

To enable the luggage compartment subwoofer amplifier, the ACM sends voltage through the enable/clip circuit. The circuit acts as both an output (to enable the amplifier) and an input (to detect an overload condition). The voltage sent by the ACM passes through a variable resistor in the amplifier, then to ground. As the amplifier reaches maximum output, the resistance in the variable resistor decreases. This decreases the voltage drop, resulting in the ACM detecting a higher voltage on the enable/clip circuit. When the voltage reaches the clip threshold, the ACM clips the audio output signal to the amplifier (heard as distortion) in order to prevent damage to the amplifier and subwoofer speaker.

The enable/clip status is based on the following voltages, as detected by the ACM :

Less than 0.4 volt: amplifier disabled
Between 3.8 and 6.7 volts (nominal): amplifier enabled
Greater than 8.5 volts: amplifier clipped

An open in the enable/clip circuit causes the speakers powered by that particular amplifier to produce no sound because the enable signal does not reach the audio amplifier. A short to ground or short to voltage can cause severe distortion to be heard in the speakers.

DTC B1A05:02 (Speaker #5: General Signal Failure) — set by the ACM (without navigation) when a fault is detected with the enable or speaker circuits between the ACM and subwoofer amplifier. This DTC can be continuous or on-demand.

This pinpoint test is intended to diagnose the following:

Luggage compartment subwoofer enclosure
Fuse
Wiring, terminals or connectors
Luggage compartment subwoofer amplifier
ACM

PINPOINT TEST H: NO SOUND FROM THE LUGGAGE COMPARTMENT SUBWOOFER

Pinpoint Test Q: Unable To Pair Bluetooth Device

Diagnostic Overview

Diagnostics in this manual assume a certain skill level and knowledge of Ford-specific diagnostic practices. Refer to Diagnostic Methods in Section 100-00 for information about these practices.

Normal Operation

When a new Bluetooth device is added, the Accessory Protocol Interface Module (APIM) and the Bluetooth device must be paired together. Most Bluetooth devices can pair with the SYNC® system, although functionality may vary. To determine if a Bluetooth device is supported, retrieve the Consumer Interface Processor (CIP) software level using the Accessory Protocol Interface Module (APIM) Software Level Check , and verify the customer device is on the compatibility list for the current CIP software level.

Pairing a Bluetooth device is accomplished through the "Add Device" selection of the phone menu. When pairing a device, the SYNC® system generates a unique Personal Identification Number (PIN) that must be entered on the Bluetooth device in order for the pairing process to be successful. There are also some device-specific actions that must take place. For additional information on the pairing process, REFER to the Owner's Literature.

Pinpoint Test R: The Steering Wheel Switches Are Inoperative Or Do Not Operate Correctly

Diagnostic Overview

Diagnostics in this manual assume a certain skill level and knowledge of Ford-specific diagnostic practices. Refer to Diagnostic Methods in Section 100-00 for information about these practices.

Refer to Wiring Diagrams Cell 130 , Audio/Navigation for schematic and connector information.

Normal Operation

There are 3 different steering wheel switch configurations:

Without SYNC®, without navigation
- VOL-, VOL+, SEEK-, SEEK+, MEDIA
- All switches are wired to the ACM
With SYNC®, without navigation
- VOL-, VOL+, SEEK-, SEEK+, MEDIA, VOICE, PHONE, OK
- The VOL-, VOL+, SEEK-, SEEK+, and MEDIA switches are wired to the ACM . The VOICE, PHONE, and OK switches are wired to the APIM .
With SYNC®, with navigation
- VOL-, VOL+, SEEK-, SEEK+, MEDIA, VOICE, PHONE
- All switches are wired to the ACM

Voltage is sent from the ACM or APIM to the steering wheel switches, and the same module grounds the return circuit. The VOL-, VOL+, SEEK-, and SEEK+ switches share signal and return circuits, while the VOICE, MEDIA, PHONE and OK switches share a separate set of signal and return circuits.

For all configurations, when a switch is pressed, the voltage is routed through a specific resistor value for each function. The ACM or APIM then uses the reference voltage to determine which control input function has been selected.

DTC B11BA:1C (Steering Wheel Audio Switch Pack: Circuit Voltage Out of Range) — set by the ACM (without navigation) and ACM (with navigation) when the reference voltage to the steering wheel switches is out-of-range. This can be caused by a number of different failures on the steering wheel switches circuit except for a stuck switch or a short to ground. This DTC applies to the VOL-, VOL+, SEEK-, SEEK+, and MEDIA switches.
DTC B11BA:63 (Steering Wheel Audio Switch Pack: Circuit / Component Protection Time-Out ) — set by the ACM (without navigation) and ACM (with navigation) when a steering wheel switch is detected as active for more than 120 seconds during normal operation, or for more than 3 seconds during the self-test. A short to ground does not set this DTC, as the reference voltage falls out-of-range, resulting in DTC B11BA:1C being set. This DTC applies to the VOL-, VOL+, SEEK-, SEEK+, and MEDIA switches.
B1201:1C (Steering Wheel Audio Switch Pack 2: Circuit Voltage Out of Range) — set by the ACM (with navigation) when the reference voltage to the steering wheel controls is out-of-range. This can be caused by a number of different failures on the steering wheel switch circuit except for a stuck switch or a short to ground. This DTC applies to the VOICE and PHONE switches.
B1201:1C (Steering Wheel Audio Switch Pack 2: Circuit Voltage Out of Range) — set by the APIM (with SYNC® and without navigation) when the reference voltage to the steering wheel controls is out-of-range. This can be caused by a number of different failures on the steering wheel switch circuit except for a stuck switch or a short to ground. This DTC applies to the VOICE, PHONE, and OK switches.
B1201:63 (Steering Wheel Audio Switch Pack 2: Circuit / Component Protection Time-Out) — set by the ACM (with navigation) when a steering wheel switch is detected as active for more than 120 seconds during normal operation, or for more than 3 seconds during the self-test. This DTC applies to the PHONE and VOICE switches.
B1201:63 (Steering Wheel Audio Switch Pack 2: Circuit / Component Protection Time-Out) — set by the APIM (with SYNC® and without navigation) when a steering wheel switch is detected as active for more than 120 seconds during normal operation, or for more than 3 seconds during the self-test. This DTC applies to the VOICE, PHONE, and OK switches.

This pinpoint test is intended to diagnose the following:

Pinpoint Test W: The Front Display Interface Module (FDIM) Is Inoperative (With Navigation)

Diagnostic Overview

Diagnostics in this manual assume a certain skill level and knowledge of Ford-specific diagnostic practices. Refer to Diagnostic Methods in Section 100-00 for information about these practices.

Refer to Wiring Diagrams Cell 130 , Audio System/Navigation for schematic and connector information.

Normal Operation

The Audio Front Control Module (ACM) enables the Front Display Interface Module (FDIM) by sending voltage through the enable circuit.

Video display information is sent to the FDIM from the ACM through a dedicated video cable. The video cable is only serviced by overlaying a new cable.

If there is a fault in the video cable, the FDIM may illuminate very dimly and have a greyish appearance. This is because the enable circuit is still active and enables the illumination, but no video signal reaches the FDIM .

If the vehicle is equipped with a rear view camera, the video feed from the camera is hardwired to the FDIM .

For all other display information, including the climate control and SYNC® system displays, messages are sent to the ACM via the Medium Speed Controller Area Network (MS-CAN). The ACM then alters the video feed to the FDIM based on the messages it receives.

Pinpoint Test AB: The Position Cursor Is Inaccurate

Diagnostic Overview

Diagnostics in this manual assume a certain skill level and knowledge of Ford-specific diagnostic practices. Refer to Diagnostic Methods in Section 100-00 for information about these practices.

Normal Operation

The primary source of vehicle location for the navigation system is the Audio Front Control Module (ACM) receiving the position signal through the Global Positioning System (GPS) antenna (integral to the satellite radio antenna).

In addition, the ACM receives the navigation rolling wheel count signal from the Instrument Panel Cluster (IPC), which gateways the signal from the ABS module. This secondary signal is used to calculate vehicle position when the GPS signal is lost. It also supports the adaptive learning function of the ACM , whereby the ACM can compensate for long-term differences between the GPS signal location and the actual distance traveled by the vehicle.

If DTC B119F:01 or DTC B119F:13 are present, GO to Pinpoint Test AA to diagnose a concern with the GPS antenna.
