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. 3 Networking System C Generator D Ignition/Starter Switch E1 Light Switch E284 Garage Door Opener Control Head G65 High Pressure Sensor G238 Air Quality Sensor G397 Rain/Light Recognition Sensor GX12 ESP Sensor Unit H12 Alarm Horn J104 ABS Control Module J217 Transmission Control Module J234 Airbag Control Module J245 Power Sunroof Control Module J255 Climatronic Control Module J285 Instrument Cluster Control Module J343 Left HID Headlamp Control Module J344 Right HID Headlamp Control Module J345 Towing Recognition Control Module J367 Battery Monitoring Control Module J386 Driver Door Control Module J387 Front Passenger Door Control Module J388 Left Rear Door Control Module J389 Right Rear Door Control Module J393 Comfort System Central Control Module J394 Roof Shade Control Module J446 Parking Aid Control Module J500 Power Steering Control Module J502 Tire Pressure Monitoring Control Module J518 Accessory/Start Authorization Control Module J519 Vehicle Electrical System Control Module J525 Digital Sound System Control Module J527 Steering Column Electronics Control Module J530 Garage Door Opener Control Module J532 Voltage Stabilizer J533 Data Bus On Board Diagnostic Interface J540 Electromechanical Parking Brake Control Module J605 Rear Lid Control Module J623 Engine Control Module J685 Front Information Display Control Head J720 Front Passenger Seat Adjustment Control Module J745 Cornering Lamp and Headlamp Range Control Module J764 Electronic Steering Column Lock Control Module J772 Rearview Camera System Control Module J794 Information Electronics Control Module 1 J810 Driver's Seat Adjustment Control Module J840 Battery Regulation Control Module J841 Electrical Drive Control Module J842 Air Conditioner Compressor Control Module J866 POower Adjustment Steering Column Control Module N511 Decoupler Pressure Actuator R Radio R215 External Multimedia Device Interface T16 16-pin Connector V Windshield Wiper Motor V2 Fresh Air Blower V107 Defroster Door Motor V108 Left Footwell Door Motor V110 Left Center Vent Motor V158 Left Temperature Door Motor V159 Right Temperature Door Motor V299 Left Side Vent Motor V425 Fresh Air/Recirculation/Back Pressure Door Motor J234 J841* N511* J685 V2 V107 V108 V110 V158 V159 V299 V425 J446 J502 J255 J388 J389 H12 J245 J394 J764 D E1 J866 E284 J530 G65 G238 R J794 J367 J532 C V G397 J840* CAN-Bus LIN Bus MOST Bus Private CAN-Bus4 Networking System Data Bus On-Board Diagnostic Interface J533 (Gateway) Diagnosis CANMOST-Bus N A C t r o f m o C LIN-Bus Comfort CAN Comfort CAN Ring Break Diagnosis Line Suspension/Instrument Cluster CAN Powertrain CAN Data Bus On-Board Diagnostic Interface J533 Data Bus T erminology At the time of printing, there were discrepancies between the Service Information and Guided Fault Finding (GFF).

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. S470_054 MOST bus in the 2011 T ouareg DVD Changer Radio Control Module for Digital Dound Package Control Module in Dash Panel Insert Diagnostic Interface for Data-Bus Control Module for Information 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 speci? c recipient ? Cyclic and event-controlled data transfer ? High level of safety against disturbance and external interference Data transfer with the aid of ? ber-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  ber-optic cable. It consists of polymethylmethacrylate (PMMA), which is the actual  ber-optic cable. In it, light travels according to the principle of total re ection, with almost no loss. The cladding is an optically transparent re ective coating around the core that is needed for total re ection. The black casing made from polyamide protects the core from outside light. The colored outer cover is for identi cation, protection against outside damage, and insulation against temperature. Caution: To prevent any loss in the transfer of data, the front surface of the  ber-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  ber-optic cable. Structure of Fiber-Optic Cable Outer Cover Black Casing Front Surface Core Cladding Note: More information regarding MOST bus operation is found in SSP 872803, Data-Bus Technology.14 Networking System Ring Break Diagnosis Wire The infotainment system has a ring break diagnosis wire to simplify fault ? nding 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 Works Ring break diagnosis is initiated by the VAS program “Ring break diagnosis MOST bus” and has two test cycles. In the ? rst 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 ? ber-optic cable from the preceding control unit on the MOST data bus.
