Principles of Operation

Note. The smart junction box (SJB) is also known as the generic electronic module (GEM).

Audio Control Module (ACM)

The audio system can be operated while the key is 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 moved to OFF and a front door has not been opened. The audio control module (ACM) sends AC voltage audio signals to the speakers or to the amplifier, depending on vehicle configuration. The ACM can produce its own DTCs, which can be communicated to the scan tool through the medium speed controller area network (MS-CAN), or can be retrieved through the ACM self-test by simultaneously pressing presets 3 and 6. The ACM communicates via the MS-CAN.

The navigation module is integrated into the ACM and controls the operation and the interface between the user, the vehicle subsystems, and the external components. The navigation module is on the MS-CAN and can be diagnosed with a scan tool.

The vehicle navigation system guides the user to a pre-entered destination. A navigation map DVD stored in the navigation module sends route calculation data to the ACM. The ACM audibly and visually instructs the user of the maneuvers required to arrive at the destination entered.

In order to calculate the initial vehicle position, the global positioning system (GPS) antenna is used to track several available satellites simultaneously. The GPS antenna only receives data and does not communicate with the satellites. A gyroscope, integral to the navigation module, monitors the pitch and yaw of the vehicle created during cornering or turning. Vehicle speed and reverse signals received through the MS-CAN are also used to detect vehicle speed and direction changes.

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.

The satellite audio system consists of a satellite digital audio receiver system (SDARS) module, a satellite radio antenna, and an antenna cable. The satellite radio antenna receives digital audio signals and sends them to the SDARS module, where the signals are converted and sent to the ACM, the rear entertainment module (RETM) (if equipped with the DVD entertainment system but not the SYNC system), or the accessory protocol interface module (APIM) (if equipped with the SYNC system). The SDARS module communicates via the MS-CAN.

Antenna - AM/FM

For sedans, the combination AM/FM antenna is located on the rear window glass. An antenna isolator module is used to reduce interference from the rear window defroster. The audio signals are sent to the ACM via a coaxial cable. The AM/FM antenna cannot be replaced separately from the rear window glass.

For wagons, a fixed-mast AM/FM antenna is used, rather than an in-glass antenna.

Antenna - Satellite Radio

The satellite radio antenna is located on the roof of the vehicle. The antenna receives digital audio signals and sends them to the SDARS module through the satellite radio antenna cable. For sedans, a dedicated satellite radio antenna is used. For wagons, a combination AM/FM/satellite radio antenna is used.

Subwoofer

The Audiophile system is equipped with a subwoofer and subwoofer amplifier. The ACM controls the subwoofer amplifier through the enable/clip detection circuit. The enable/clip detection circuit carries out 2 functions: to turn the amplifier on, and to indicate to the ACM when the subwoofer output distortion signal reaches a damaging level. The ACM then clips the audio output signal to prevent damage to the subwoofer.

The DVD entertainment system utilizes a RETM, mounted to the headliner, which provides video playback on a screen when a video DVD is played. The audio signals to the rear speakers are routed from the ACM through the RETM. The wake-up signal for the RETM is sent from the ACM through the MS-CAN.

Single-Play Mode

In single-play mode, any audio input routed through the RETM is broadcast through all of the vehicle speakers. These audio inputs include the RETM, satellite audio, SYNC audio, and peripheral gaming devices plugged into the RETM.

Dual-Play Mode

In dual-play mode, the ACM continues to control the output to the front speakers, while the RETM mutes the audio to the rear speakers. The RETM continues to broadcast the rear audio source to the headphones. When the headphones are set to channel A, all audio sources can be accessed. When the headphones are set to channel B, only the DVD audio and auxiliary audio sources (such as a gaming system) can be sent to the headphones.

The SYNC system allows interaction with several types of customer devices, including mobile phones and media devices. The system is comprised of the APIM, a microphone (located in the interior rear view mirror), the universal serial bus (USB) cable and port, and the audio input jack. 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). The 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 controller are network (CAN).

The APIM can receive inputs from the following audio sources

1. USB port
2. Audio input jack
3. SDARS module
4. 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 will only play 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.

If the vehicle is equipped with satellite audio, the audio signals from the SDARS module are sent to the APIM, rather than directly to the ACM. The APIM then relays the satellite audio signals to the ACM.

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 32 feet.

Only one Bluetooth® phone and one Bluetooth® 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.

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 will 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 will automatically index the information. This may take up to 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 will update 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, ring tones, 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 via the MS-CAN.

Voice Recognition For Vehicles With Navigation And The SYNC System

When a vehicle is equipped with both the navigation system and the SYNC system, the interaction between the audio system components is unique for voice recognition.

Both the navigation ACM and the APIM utilize voice-recognition, but in order for the modules to determine which one should be acknowledging the voice command, the voice command set is different. This allows the modules to identify the intended source when the VOICE button is pressed. The VOICE (an icon of someone speaking) and PHONE (an icon of a phone and an up-and-down arrow) buttons are wired to the navigation ACM, rather than to the APIM (as they are in non-navigation audio systems).

When the audio system enters voice recognition mode, the ACM sends a CAN message to the APIM to enter voice recognition mode. The microphone is wired directly to the APIM, which relays the microphone input to the ACM through dedicated wiring. Control of the voice functions is given to whichever module is indicated by the first voice command.

Steering Wheel Controls

The steering wheel controls consist of a series of resistors. Each steering wheel control 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.

Audio Input Jack - Vehicles Without The SYNC System

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

Audio signal flow varies greatly depending on vehicle content.

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, ring tones, 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.

Network Communication

The following audio system components communicate via the medium speed controller area network (MS-CAN)

1. Audio control module (ACM)
2. Navigation ACM
3. Satellite digital audio receiver system (SDARS) module
4. Rear entertainment module (RETM)
5. Accessory protocol interface module (APIM)

Pinpoint Test B: Poor Quality/Distorted/No Sound from One or More Speakers (Not All Speakers)

Refer to appropriate SYSTEM WIRING DIAGRAMS article, Audio System/Navigation for schematic and connector information.

The audio control module (ACM) directs audio signals to the speakers and to the rear entertainment module (RETM) (if equipped) in the form of a fluctuating AC voltage. The rear door speakers receive audio signals through the RETM (if equipped) or directly from the ACM.

If the vehicle is equipped with the DVD entertainment system, the RETM mutes the speaker output to the rear speakers when the audio system is in dual-play mode. Make sure the audio system is in single-play mode before diagnosing a symptom of no sound to the rear speakers.

For the navigation system, if the voice guidance setting is set to zero rather than to off, it may appear that the front speakers intermittently produce no sound. Make sure the voice guidance setting is not set to zero before addressing a concern with the front speakers.

1. DTC B2965 (Audio System Speaker Circuit Fault) - sets when an open, a short to ground, or a short to voltage is detected on the front door or rear door speaker circuits. The ACM checks for faults once every 500ms during normal operation. The following should also be noted: The Audiophile ACM does not check for opens in the front door speakers. The navigation ACM does not check for opens.

For some audio systems, a short to ground or short to voltage in the circuitry to one of the speakers will cause all speakers to lose sound due to the built-in overload protection feature of the ACM. In this case, DTC B2965 will set in the ACM, and this pinpoint test should be followed to isolate the damaged circuit.

This pinpoint test is intended to diagnose the following

1. Wiring, terminals or connectors
2. Speaker
3. RETM (if equipped)
4. ACM

Note. Use the correct probe adapter(s) when making measurements. Failure to use the correct probe adapter(s) may damage the connector.

Note. Make sure the audio system is in single-play mode before beginning this pinpoint test, or the results will not be accurate.

Pinpoint Test C: The Subwoofer is Inoperative/Does Not Operate Correctly - Audiophile

Refer to appropriate SYSTEM WIRING DIAGRAMS article, Audio System/Navigation for schematic and connector information.

The subwoofer speaker is powered by a separate subwoofer amplifier. For wagons, the subwoofer speaker is integral to the subwoofer enclosure. For sedans, there are 2 subwoofer speakers connected to the subwoofer amplifier through circuits VME01 (GN/VT), RME01 (GY), VME02 (VT), and RME02 (YE). The subwoofer receives audio signals from the ACM through circuits VME22 (VT/GN) and RME22 (GN/WH). The subwoofer amplifier receives voltage (at all times) through circuit SBP38 (BN/RD), and ground through circuit GD148 (BK/YE).

To enable the subwoofer amplifier, the ACM sends voltage through the enable/clip circuit SME23 (VT/RD). The circuit acts as both an output (to enable the amplifier) and an input (to detect an amplifier overload condition). A variable resistor in the subwoofer amplifier modifies the voltage signal from the ACM. In the event of an overload, the ACM clips the audio output signal to the amplifier (heard as distortion), in order to prevent damage to the amplifier and speakers.

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

1. Less than 0.4 volts: amplifier disabled
2. Between 3.8 and 6.7 volts: amplifier enabled
3. Greater than 8.5 volts: amplifier clipped

An open in circuit SME23 (VT/RD) will cause the subwoofer to produce no sound, because the enable signal will not reach the subwoofer amplifier. A short to ground or short to voltage can cause severe distortion to be heard from the subwoofer.

1. DTC B1154 (Subwoofer #1 Short to Ground) - sets when a short to ground is detected on circuit RME22 (GN/WH) or VME22 (VT/GN). This DTC only sets during the on-demand self-test.
2. DTC B1155 (Subwoofer #1 Short to Battery) - sets when a short to voltage is detected on circuit RME22 (GN/WH) or VME22 (VT/GN). This DTC only sets during the on-demand self-test.
3. DTC B2913 (Audio Subwoofer Not Connected) - sets when the ACM does not detect the subwoofer through circuit SME23 (VT/RD) during the subwoofer connection test (part of the ACM self-test).

This pinpoint test is intended to diagnose the following

1. Fuse
2. Wiring, terminals or connectors
3. Subwoofer amplifier
4. Subwoofer speaker
5. ACM

Note. Use the correct probe adapter(s) when making measurements. Failure to use the correct probe adapter(s) may damage the connector.

Pinpoint Test D: The Audio Does Not Reduce When The Parking Aid Tone Sounds

Refer to appropriate SYSTEM WIRING DIAGRAMS article, Audio System/Navigation for schematic and connector information.

When the parking aid module (PAM) detects an object in range, it sounds an alarm and grounds circuit CME05 (GN/BU) to the ACM. When the ACM detects the circuit grounded, it reduces the audio output until the parking aid module signal is no longer detected.

1. DTC B2384 (Audio Reverse Park Aid Mute Ckt Failure) - sets during the on-demand test if the mute circuit is detected as active. This could be because the vehicle is in reverse (R) and an object is within range of the parking aid system. Put the vehicle in park (P) while running the on-demand self-test to eliminate this as a possible cause of the DTC.

This pinpoint test is intended to diagnose the following

1. Wiring, terminals or connectors
2. Parking aid system concern

1. D1 CHECK THE ACM DTCs Put the vehicle in park (P). Carry out the ACM on-demand self-test. Is DTC B2384 present? YES : Go to D2 . NO : REFER to «PARKING AID»(/ford/taurus-x/i-2007-2009/remont/collisionavoidance/#parking-aid-system) article to continue diagnosis of the parking aid system.
2. D2 CHECK THE PARKING AID MODULE OUTPUT Key in OFF position. Disconnect: PAM C3267 Carry out the ACM on-demand self-test. Is DTC B2384 present? YES : REPAIR circuit CME05 (GN/BU) for a short to ground. CLEAR the DTCs. REPEAT the self-test. NO : REFER to «PARKING AID»(/ford/taurus-x/i-2007-2009/remont/collisionavoidance/#parking-aid-system) article to continue diagnosis of the parking aid system.

Pinpoint Test E: The Steering Wheel Controls Are Inoperative/Do Not Operate Correctly

Refer to appropriate SYSTEM WIRING DIAGRAMS article, Audio System/Navigation for schematic and connector information.

There are 3 different steering wheel controls configurations

1. Non-navigation, without the SYNC system VOL-, VOL+, SEEK-, SEEK+, MEDIA, MUTE
2. Non-navigation, with the SYNC system MENU-, MENU+, VOICE, OK, PHONE
3. Navigation, with or without the SYNC system VOL-, VOL+, SEEK-, SEEK+, MEDIA, VOICE

For vehicles without both navigation and the SYNC system, all the steering wheel controls are wired to the audio control module (ACM). Voltage is sent from the ACM to the steering wheel controls through circuit VME14 (GY/YE), and the ACM ground the reference voltage through circuit RMC27 (WH/BN).

For vehicles with the SYNC system but not navigation, all the steering wheel controls are wired to the accessory protocol interface module (APIM). Voltage is sent from the APIM to the steering wheel controls through circuit CMM15 (GY/BU), and the APIM grounds the reference voltage through circuit CMM14 (WH).

For vehicles equipped with navigation, all the steering wheel controls are wired to the ACM, regardless of whether the vehicle is equipped with the SYNC system or not.

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.

1. DTC B1117 (Audio Steering Wheel Button Stuck) - set by the ACM or the APIM (depending on vehicle configuration) when a steering wheel control switch is detected as active for more than 120 seconds during normal operation, or for any duration during the self-test. A short to ground on VME14 (GY/YE) should not set this DTC, as the reference voltage would fall out-of-range, resulting in DTC B1136 or B2404 being set.
2. DTC B1136 (Audio Steering Wheel Switch #2 Circuit Failure) - set by the APIM 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 controls circuit except for a stuck button or a short to ground in circuit CMM14 (WH).
3. DTC B2404 (Audio Steering Wheel Switch Circuit Fault) - set by the ACM 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 controls circuit except for a stuck button a short to ground in circuit RMC27 (WH/BN).

This pinpoint test is intended to diagnose the following

1. Wiring, terminals or connectors
2. Clockspring
3. Steering wheel controls
4. ACM
5. APIM (if equipped)

Note. Use the correct probe adapter(s) when making measurements. Failure to use the correct probe adapter(s) may damage the connector.

Pinpoint Test I: The Satellite Audio Is Inoperative/Does Not Operate Correctly - Vehicles Without DVD Entertainment System

Refer to appropriate SYSTEM WIRING DIAGRAMS article, Audio System/Navigation for schematic and connector information.

The satellite digital audio receiver system (SDARS) module receives voltage through circuit SBP03 (BU/RD), and ground through circuit GD103 (BK/BU). Digital signals are received by the satellite radio antenna and sent to the SDARS module, which converts the signals to analog and sends them to either the audio control module (ACM) or to the accessory protocol interface module (APIM) (if equipped).

If there is an open in the satellite antenna circuit, there will be no satellite audio. The ACM display will indicate a satellite antenna concern (the method varies according to the type of ACM) when the audio system is operated in satellite radio mode. To diagnose an open in the satellite antenna circuit, go to Pinpoint Test H .

The SDARS module transmits left and right channel audio signals. When there is a fault in any of the audio signal circuits, the audio quality is reduced. If the circuits for a specific channel are shorted together, loss of audio on the entire channel will occur. This can be detected by using the SDARS module tones test.

1. DTC U0184 (Lost Communication With Radio [ACM]) - set by the SDARS module when certain medium speed controller area network (MS-CAN) messages are missing from the ACM for greater than 5 seconds. This results in loss of satellite radio functionality.

The primary source of vehicle location for the navigation system is the audio control module (ACM) receiving the position signal through the global positioning system (GPS) antenna.

In addition, the ACM receives the wheel pulse signal from the instrument cluster (IC) (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.

1. DTC B2204 (GPS Antenna Connection Open or Short) - sets when an open, short to ground, or short to voltage is detected in the GPS antenna circuit. If DTC B2204 is present, go to «Pinpoint Test L»(/ford/taurus-x/i-2007-2009/remont/entertainment-systems/#information-system-and-entertainment-systems) .
2. DTC U0155 (Lost Communication With Instrument Panel Cluster [IC] Control Module) - sets when the ACM is missing messages from the instrument cluster for greater than 5 seconds.
3. DTC U2473 (Unexpected Vehicle Speed [VSS]) - sets when the calculated vehicle distance traveled based on the wheel pulse signal does not agree with the GPS antenna location. To do this, the ACM compares the wheel pulse signal during a 4-second range, and compares it with the change in GPS antenna location. If the ACM finds that the variation is greater than 0.5% after performing this check 4 times, it sets DTC U2473. When DTC U2473 is set, the adaptive learn function is disabled. This DTC is also set when the navigation rolling wheel count signal is missing for greater than 2 seconds with the key in RUN.

This pinpoint test is intended to diagnose the following

1. GPS antenna
2. VSS signal concern

Pinpoint Test P: Voice Recognition Is Inoperative/Does Not Operate Correctly - Vehicles Without The SYNC System

Refer to appropriate SYSTEM WIRING DIAGRAMS article, Audio System/Navigation for schematic and connector information.

When the VOICE button (an icon of someone speaking) is pressed, the audio control module (ACM) detects the change in reference voltage on circuit VME14 (GY/YE) and enters voice recognition mode. A microphone located in the interior rear view mirror receives the voice command and sends a signal to the ACM through circuits VMN02 (WH/BN) and RMN02 (VT/BN). Power to the interior rear view mirror is provided through circuit CBP41 (BU), and ground through circuit GD133 (BK).

The microphone test is available through the integrated diagnostic system (IDS). Running this test causes the ACM to produce a test tone. If the system is operating correctly, the microphone detects the tone and produces a signal to the ACM indicating the tone was heard.

Most Bluetooth® devices will pair with the SYNC system, although functionality will 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 V: Voice Recognition Is Inoperative/Does Not Operate Correctly - Vehicles With The SYNC System

Refer to appropriate SYSTEM WIRING DIAGRAMS article, Audio System/Navigation for schematic and connector information.

When the VOICE button (represented by an icon of someone speaking) is pressed, it changes the reference voltage on circuit VME54 (BU/OG), and the audio system enters voice recognition mode. If the vehicle is equipped with navigation, the VOICE switch is wired to the audio control module (ACM). If the vehicle is not equipped with navigation, the VOICE switch is wired to the accessory protocol interface module (APIM). A microphone located in the interior rear view mirror receives the voice command and sends a signal to the APIM through circuits VMN02 (WH/BN) and RMN02 (VT/BN). The microphone is also used to detect outgoing audio during a phone call.

If the vehicle is equipped with navigation, the APIM receives the microphone input, and also broadcasts it to the ACM through circuits VMN02 (WH/BN) and RMN02 (VT/BN). This is to allow voice commands specific to the navigation system to be handled directly by the ACM. The first voice commands spoken determine which system handles the voice commands.

1. DTC B1038 (Microphone Input Circuit Failure) - set by the APIM during the on-demand self-test if the APIM does not detect the microphone.
2. DTC B2633 (Driver-Front Microphone Circuit Failure) - set by the ACM during the microphone test when the ACM does not receive an adequate signal from the microphone when the test tone is sounded.

This pinpoint test is intended to diagnose the following

1. Fuse
2. Wiring, terminals or connectors
3. Steering wheel controls
4. Microphone (part of the interior rear view mirror)
