The Networking Concept
The 2011 Touareg has the following data bus systems:
• 9 Main CAN-Busses (500 kBits/sec)
– 6 main (connected to J533)
– 3 private (not connected to J533)
• 12 LIN-Busses (19.2 kBits/sec)
• 1 MOST-Bus (21 Mb/sec)
• 1 Ring Break Diagnosis Line
• 1 Low Voltage Differential Signaling (LVDS) Bus
All of the CAN-Buses are high speed, with a data transfer rate of 500kBit/s and are not fault tolerant. This means that if one CAN wire is unable to communicate, then all communication on the bus ceases.
Depending on vehicle options, these networks can contain up to 63 control modules.

Networking System
MOST-Bus
The Media Oriented Systems Transport Bus (MOST-Bus) is a serial bus system for transferring audio, video, voice and data signals over a fiber-optic cable. MOST is a ring-shaped network structure. A MOST network can have up to 64 MOST devices. The order of the components is determined during development and cannot be changed.

Control Module forInformation Electronics 1
The MOST bus in the 2011 Touareg has the following features:
• Optical data bus system
• Data transfer rate: 21.2 Mbit/s
• Ring topology
• Address-orientated messages to a specific recipient
• Cyclic and event-controlled data transfer
• High level of safety against disturbance and external interference
Data transfer with the aid of fiber-optics enables a considerably greater data transfer rate. Compared with radio waves, light waves have short wavelengths. They do not generate electromagnetic interfering waves and, at the same time, are not sensitive to interference from external electromagnetic sources.
13
Networking System
S470_098
Fiber-optic cable has several layers:
• The core is the main part of a fiber-optic cable. It consists of polymethylmethacrylate (PMMA), which is the actual fiber-optic cable. In it, light travels according to the principle of total reflection, with almost no loss.
• The cladding is an optically transparent reflective coating around the core that is needed for total reflection.
• The black casing made from polyamide protects the core from outside light.
• The colored outer cover is for identification, protection against outside damage, and insulation against temperature.
Caution: To prevent any loss in the transfer of data, the front surface of the fiber-optic cable must be smooth, vertical and clean. Dirt and scratches on the front surface could lead to interference and data transfer losses and it could also impair the performance of the fiber-optic cable.

Networking System
Ring Break Diagnosis Wire
The infotainment system has a ring break diagnosis wire to simplify fault finding of the MOST data bus. It is a single-core wire that is connected to all control modules on the MOST data bus. The ring break diagnosis wire starts from a node behind the Data Bus on Board Diagnostic Interface J533 and runs in a star shape to the respective control modules on the MOST data bus.
How it WorksRing break diagnosis is initiated by the VAS program “Ring break diagnosis MOST bus” and has two test cycles.
In the first test cycle J533, which is the master for this function, sends a voltage signal to the connected control modules via the ring break diagnosis wire. A constant 12-volt signal is connected to ground for ten seconds for this purpose.
The control modules on the MOST data bus then test their own voltage supply and check whether they receive a light signal via the fiber-optic cable from the preceding control unit on the MOST data bus.
The result of this check is sent to the data bus diagnostic interface via the ring break diagnosis wire. Using the data received, the diagnosis interface can recognize if there is a fault in one of the control units on the MOST data bus or if there is a fault in the fiber-optic cable.
s473_522Ring break diagnosis wire on MOST data bus
J533
A second test cycle is started if no fault is located. In this cycle, the data bus diagnostic interface instructs the control modules on the MOST data bus to transmit the light signals with only half light output.
This corresponds with a 3dB failure of the light signals. If this weakened signal is no longer received by a control unit, this indicates a failure and a damaged point in the fiber optic cable.
If a damaged point is suspected in the MOST data bus fiber-optic cable, the cable should be tested optically according to the specifications in ElsaWeb. If a faulty control module is suspected, the optical substitute control unit VAS 6186 should be used according to the instructions in ElsaWeb.
Caution: Never look directly into the fiber-optic cable when working on the MOST data bus! The connections on the fiber-optic cable may not come into contact with liquids or be touched with bare hands.

5th Generation Immobilizer
The 2011 Touareg uses Immobilizer V. The primary change between the previous Immobilizer and Immobilizer V is that all processes must be done online with the FAZIT database using your GEKO ID.
The following tester functions are available:
• Adapting Immobilizer
• Component protection of master (Gateway) combined system
• Component protection of individual components
With the component protection master function, the Gateway is programmed and authorized as a component protection master by FAZIT. This is a key control module for the following component protection activities among individual components.
Component protected modules:05 – Access/Start Authorization Control Module J51815 – Airbag Control Module J23406 – Front Passenger Seat Adjustment Control Module J72036 – Driver Seat Adjustment Control Module J81056 – Radio R17 – Instrument Cluster Control Module J28547 – Digital Sound System Control Module J525 (DYNAUDIO) 08 – Climatronic Control Module J25509 – Vehicle Electrical System Control Module J51919 – Data Bus On-Board Diagnostic Interface J533 (Gateway)5F – Information Electronics Control Module 1 J794
For the above control modules to operate correctly, they must be authorized online by FAZIT. If the control modules are not adapted, their functions will be restricted, and they may not operate at all.
Caution: Never swap the above control modules between vehicles for testing!

Special Functions
The Electronic Ignition Lock
DesignThe new remote key fob does not use a physical key, but has three buttons to unlock and lock the vehicle, and to open the rear lid.
If the VW emblem is pressed (along with an additional release under the top of the key), a plastic emergency key can be released from the key. This kay can be used to lock the glove compartment to protect valuables when handing the vehicle over to a valet
Also, when the triangular cover at the rear of the driver’s door handle is removed, a mechancial lock is exposed. The emergency key can be used in this lock to unlock the door.
The chrome clasp can also be used as a ring holder, as seen on Passat and CC keyfobs.

Infotainment Introduction
Infotainment Interfaces
There are two main types of electrical connections:
1. A connection used to communicate with vehicle components or control modules for on-board electronics 2. Operator interfaces for external devices or storage media
Interfaces for On-Board ElectronicsThe infotainment system can exchange information with other data bus subscribers using the Data Bus on Board Diagnostic Interface J533. For example, the Climatronic control module can share information on the Convenience CAN-bus.
Some devices use several interfaces to exchange information within the infotainment system. The control module above shows a CAN-Bus and Most-Bus interface.
Interfaces for Connecting External Devices and Storage Media.External devices can be connected to the infotainment system either wirelessly via Bluetooth or by plugging an adapter cable into the media-in interface in the glove compartment.
The Information Electronics Control Module 1 J794 has two SD slots for memory cards.

Information Electronics Control Module 1 J794
This central component of the infotainment system is located in the glove compartment and has several function modules inside a single housing.
The following modules have been integrated into J794:
• Central Processing Unit (CPU)
• Integrated DVD drive
• Media player
• Navigation module
• Bluetooth module for hands-free operation
System Module
Together with the hard drive and the processor CPU (Central Processing Unit), this module forms the foundation for J794. The integrated hard drive has a storage capacity of 60 gigabytes, of which 18 gigabytes are reserved as a partition for the customer media library. The larger partition of 40 gigabytes is provided for navigation data, media databases, Traffic Message Channel (TMC) folders or address books.
Automotive hard drives are specifically developed for use in vehicles and are not as sensitive to vibrations as commercially available computer hard drives.
The RAM (Random Access Memory) for the CPU has a memory capacity of 256MB and a flash memory area of 256MB for system updates.
J794 is the master on the MOST data bus for the infotainment system and controls the other infotainment components. It regulates the network management for the infotainment system and the timing of the MOST data bus protocol.
J794 is connected to the External Audio Source Connection R199 (media-in interface; also located in the glove compartment) to allow use of external audio and video sources.

RNS 850 Radio and Navigation System
Voice Control
The Information Electronics Control Module 1 J794 makes it possible to switch between the infotainment functions with spoken commands, and to select address book entries or media titles. This means that a text passage made up of an album, artist and title for the media player is recognized as a complete text block.
The entry must be spoken freely without pausing. This is also true for navigation. The country, town, street and house number are recognized as a complete text block.
The voice entry system can also set a reference to the desired song if it is an international music track and the title is pronounced in the user’s language instead of in the original language of the track.
It is also possible for the system to learn the user’s pronunciation to improve voice recognition. During voice training, the infotainment system learns how to correctly interpret the individual characteristics of the user’s pronunciation.
Management of Gracenote Data
Gracenote is an international database, on which data on millions of music tracks is managed using only text information. The album name, track and artist are stored in the database.
The data from Gracenote is stored on the system partition of J794.
Using MP3s as an example, if the system recognizes information such as the title of the song, it can also display text indicating the artist or the album on which the track appeared.
Bluetooth Module
This optional interface can be used to pair a Bluetooth-compatible mobile phone for use with the hands-free system.
Also, address books can be transferred to J794 or audio data can be played back in real time (A2DP).

Note: Depending on the data format and codec used, the playback of certain music tracks or video data may not be possible.
Note: The media player does not support the copying license for data download from music or video databases (DRM).
Technical FeaturesThe data rate at which tracks are transferred for playback is 160kbit/s to 320kbit/s for audio data and 2000kbit/s for video data due to the larger quantity of data to be transferred.
Picture and video output uses a maximum resolution of up to 720x576 pixels. Higher resolutions are not displayed.
If image files such as CD covers are a part of the data medium, they can be imported as smaller images and displayed by the infotainment system (max. size 800x800 pixels).
The following data media are suitable for playback on the infotainment system:
• Audio CDs with up to 80 minutes playing length
• Standard DVD videos
• DVD-compatible DVD audio
• CD-ROM, CD-R, CD-RW (audio data CD) up to a maximum of 700MB using Joliet file system single- and multi-session
• DVD+, DVD-R, DVD-RW up to max. 4.7GB, dual-layer DVD up to max. 8.5GB using Joliet file system, only single session, UDF
• SD and MMC memory cards up to max. 2GB
• SDHC memory cards up to max. 32GB
The playability of stored audio and video data depends on whether the playback device uses the same codecs as were used to record the data.
A codec is a method of digital encoding, such as a music track with simultaneous data compression. It is then decompressed and decoded upon playback. The codecs must be stored in the recording and playback devices. They are not transferred with the playback data. If the recording device uses a codec that the playback device does not have, the data cannot be played on the playback device.
J794 uses current standard codecs. Other codecs can cause problems with the playback of some data or may not play it, even if the playback device supports the data format used. Data structures with up to 1000 folders and a maximum of 4000 files can be managed by J794.

The central element of the DynAudio sound system is an amplifier delivering 620 watts with surround control (J525). It is located in the luggage compartment near the left-side wheel housing and has 10 output stages for connecting a maximum of 12 loudspeakers. The amplifier communicates with the infotainment system via the MOST data bus.
A microphone built into the headliner detects the noises in the interior. These noises are analyzed by the amplifier electronics and the playback signal is then adjusted depending on the frequency and sound level. This process is called automatic playback signal adjustment.
The surround control (Dolby 5.1, if supported by the data medium) allows you to set up an optimum surround sound, which faithfully reproduces sound such as concert hall acoustics in relation to your position inside the vehicle

Service
Updating Navigation DataCompared to previous procedures, only the service department can transfer navigation data from DVD. In addition to the latest data DVD, the service department requires an activation document that contains an activation code (PIN).
The vehicle needs to be connected to a VAS scan tool for online activation. Due to the time needed to copy the data from the data DVD to the Information Electronics Control Module 1 J794 (approx. 1-2 hours), the vehicle should be connected to an external power supply for the update.
The activation code can only be used once and expires after activation and successful transfer of the data.
Depending on the country, different collections of navigation data are available to the service department on DVD (see glossary).
Customers no longer receive a navigation DVD when the vehicle is delivered and they cannot order one.
Update ProcessIf a customer wants their navigation system to be updated, the latest data DVD must be available in the service department. If so, the update can be performed immediately. If no activation document is available, it must be ordered using ETKA.
Connect the VAS scan tool (e.g. VAS 5051) to activate the data copied from the latest DVD. Enter the activation code first using the “Guided Function” menu.
Enter the activation code from the activation document on the tester to activate the navigation data online. After online activation, the data transfer from DVD to the J794 (the tester does not necessarily have to be connected) and perform a function test.
If a data update cannot be activated, it may be an indication that the activation code has expired or is not valid.
