System Diagram

Network Message Chart

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 Module Communications Network, Diagnosis and Testing).
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.

AM / FM Radio

The AM / FM roof-mounted antenna receives analog radio waves and sends them through the 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 speakers.

Audio Extended Play

This 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 60 minutes, depending on sufficient battery voltage. To turn the audio system off, the power button on the FCIM is pressed.

Audio Input Jack Mode

When a portable audio device, such as an iPod® with its available cable, is connected to the vehicle audio system through the audio input jack, audio from the device can be played through the vehicle speakers. Only the volume can be controlled by the vehicle audio controls. All other functions such as seek, fast forward, pause, etc. must be carried out on the device itself.

No metadata (information such as artist, album title, song title, and genre) is transferred when a device is connected to the audio input jack.

Bluetooth Mode

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 application specific, but will have a minimum range of 10 meters (33 feet).

The Bluetooth interface can accommodate both Bluetooth-enabled mobile phones and Bluetooth-enabled media devices. The SYNC® system allows interaction with several types of customer Bluetooth 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.

Any Bluetooth device used with the SYNC® system must first be paired with the APIM on-board Bluetooth chipset before it can become operational. 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 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 information on the pairing process, refer to the Owner's Literature.

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 and made active, the APIM disconnects any active connection and establishes a connection with the new device.

It is important to understand that while most Bluetooth devices can pair with the SYNC® system, not all Bluetooth devices have the same level of features available when interacting with the SYNC® system. To determine if a Bluetooth device or feature is supported, review the device compatibility list. Refer to www.syncmyride.com.

Compass

The GPS antenna integral to the GPSM is used to acquire the compass heading. The compass heading is sent over the CAN to be displayed on the centerstack infotainment display.

MyKey® Audio Operation

The following MyKey® feature is always enabled when a MyKey® is in use, and is not configurable on/off with an administrator key:
- Belt-Minder®: The audio system is muted, and “BUCKLE UP TO UNMUTE AUDIO" is displayed in the information display until the safety belts are buckled.

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 45%. In an attempt to exceed the limited volume, “MyKey® VOLUME LIMITED” is displayed in the information display.

Refer to the Owner's Literature for more information on MyKey®.

Speed Compensated Volume

The ACM adjusts the audio system volume based on the VSS signal to compensate for wind and road noise.

When a MyKey® is in use and the MyKey® Volume Limiter is enabled, the speed compensated volume is disabled.

Steering Wheel Switch Functions

The LH steering wheel switches operate the volume +/-, seek +/-, voice, send/receive call, and end call button functions.

SYNC® AppLink™

SYNC® AppLink™ allows the customer to control smartphone Applications by using voice commands and in-vehicle controls. Data is transferred from the customer’s device to the APIM through Bluetooth, or through the USB port with Apple® devices.

SYNC® Services - If Equipped

SYNC® Services is a subscription-based service, and requires a non-subscription-based SYNC® owner account in order to subscribe. The SYNC® Services subscription is associated with a Bluetooth-enabled mobile phone number, while the SYNC® owner account is associated with a VIN . For SYNC® owner account enrollment or SYNC® Services subscription information, refer to www.syncmyride.com.

The customer's registered mobile phone is used to access and download information from the SYNC® Services server. The information received by the customer's registered mobile phone is sent to the APIM .

The GPS antenna, integral to the GPSM , is used to detect the location and direction of the vehicle.

SYNC Services® allows the customer to connect to the following services:

Traffic (incidents, traffic flow, drive time, delays, and construction and lane closures if applicable)
Traffic alerts via text message (incidents, new construction, and/or delays for a specified route during a specified time period)

Live operator assistance is available for the following services: directions and business search.

For additional information, refer to www.syncmyride.com or “SYNC Services” in the owner’s literature.

SYNC® System

The SYNC® system is a hands-free communication and entertainment system that supports many features. All features are not available with every phone.

The SYNC® system provides the following abilities:

Connect media devices (such as an iPod® or USB device) in order to play audio files
Control the entertainment system using voice controls
Initiate an emergency assistance call (911 Assist™) when the airbags deploy
Play media files via a paired Bluetooth-enabled audio device
Produce vehicle health reports
Send and receive phone calls via a paired Bluetooth-enabled phone
Send and receive text messages via a paired Bluetooth-enabled phone

USB Audio Mode

When a portable media device, such as an iPod® with its available cable or portable mass storage such as a USB thumb drive, is connected to the vehicle audio system through the USB port, audio from the device can be played through the vehicle speakers. Functions such as volume, seek, fast forward, pause, etc. can be controlled by the vehicle audio controls.

When playing media files stored on a mass storage device such as a flash drive, the SYNC® system only plays files that do not have Digital Rights Management (DRM) protection.

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 port. The APIM uses the metadata to create indexes that can be used to sort for particular music based on the customer’s preferences. 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.

The USB port can also be used to upload vehicle Application upgrades to the APIM from a mass storage device such as a flash drive.

Voice Recognition

Voice recognition allows the audio system functions to be controlled with voice commands. This minimizes driver distraction by reducing or eliminating the need to interact with the centerstack infotainment display and/or device while driving.

When the voice steering wheel switch is pressed, an audible prompt originating at the APIM is heard from the speakers. Based on the customer’s setting, audible prompts will either be a voice or a simple tone. 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 . Refer to the Owner's Literature for more information on voice recognition.

Component Description

ACM

The ACM can be operated with the ignition in RUN, ACC, or OFF.

The ACM receives radio waves containing audio from the antenna coaxial cable 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 speakers as fluctuating AC voltage.

The ACM requires PMI when it is replaced.

Antenna

The AM / FM radio uses the fixed-mast roof-mounted antenna to receive radio waves containing audio. The radio waves are sent through the AM / FM antenna coaxial cable to the ACM , where they are amplified.

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 port, audio input jack, and connected Bluetooth media device. Mono inputs include audio from the outside device during a phone call and inputs 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 port, audio input jack, and connected Bluetooth media device. Mono outputs include audio from the Text-To-Speech (TTS) feature, incoming call ringtone, ringback tone, outside device during a phone call, voice or tone prompts initiated from the steering wheel switches and infotainment centerstack, route guidance voice or tone prompts, and SYNC® system instructions.

The Text-To-Speech (TTS) feature minimizes driver distraction by speaking certain text information so it does not have to be read from the centerstack infotainment display and/or device while driving.

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 Consumer Interface Processor (CIP) interfaces with all of the inputs to the APIM . It contains an analog-to-digital-to-analog converter, as well as the Bluetooth chipset. Any Application upgrades that are available to the consumer are loaded directly to the Consumer Interface Processor (CIP) through the USB port.

The Vehicle Interface Processor (VIP) provides an interface between the Consumer Interface Processor (CIP) and the vehicle. Its main functions are controlling the APIM power management and translating inbound and outbound CAN signals. In addition, the Vehicle Interface Processor (VIP) queries the modules on the network to retrieve any Diagnostic Trouble Codes (DTCs) when a vehicle health report is requested.

The APIM requires programming when it is replaced.

Audio Input Jack

The audio input jack can be used to play audio files from an audio device connected through a 1/8-inch (3 mm) audio jack.

Audio signals are sent from the audio input jack to the APIM .

There are no power or ground circuits to the audio input jack.

FCDIM

The FCDIM can be operated with the ignition in RUN, ACC, or OFF.

The FCDIM displays infotainment data received from various modules over the CAN . If the FCDIM loses the signal from any of these modules, only those specific displays will be inoperative. For more information,
Refer to: Information and Entertainment System - System Operation and Component Description (415-00B Information and Entertainment System - General Information - Vehicles With: AM/FM/CD/SYNC, Description and Operation).
See Module Network Input Messages - FCDIM .

FCIM

The FCIM can be operated with the ignition in RUN, ACC, or OFF.

The FCIM audio system buttons provide one of the methods with which the customer interacts with the infotainment system. It transfers button press data over a dedicated LIN to the FCDIM .

The FCIM is separate from the ACM .

GPSM

The 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 through the CAN to the APIM .

The GPSM requires PMI when it is replaced.

Steering Wheel Switches

The LH steering wheel switches contain series of resistors. Each steering wheel switch function corresponds with a specific resistance value within the switch.

The FCDIM sends a 5-volt reference voltage to the LH steering wheel switches on the input circuits. When a switch is pressed, the voltage is routed through the corresponding resistor(s), and then to ground through the FCDIM . The FCDIM 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 steering wheel switch inputs are sent as network messages from the FCDIM to the APIM to control SYNC® functions, or to the ACM to control audio functions.

SYNC® Microphone

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 .

USB Port

Data is sent from the USB port to the APIM through the USB cable.

The USB port is part of the USB cable, and cannot be replaced separately.

The USB port is powered through the USB cable by the APIM , and can be used to power and/or charge a device if the device supports this feature. If the device does not support this feature, an external power source is needed in order to power the device.
