Telematics

General Information

The Telematics system is integrated into the vehicle Communication system. The Telematics system is linked to the Communication system via the CAN-Bus to the Data Bus On Board Diagnostic Interface (J533).

Telematics is an in-vehicle, personal communication system using cellular, Internet and Global Positioning System (GPS) technologies to provide the customer with safety, security and convenience services.

GPS is a "constellation" of 24 satellites that orbit the earth and constantly broadcast radio signals. The Telephone/Telematics Control Module (J526) receives GPS data, decodes it, and transmits the vehicle's location to the service provider's call center via the national cellular network.

Telematics services for Audi customers are provided by OnStar(R) via a dedicated call center. Service plans may provide route directions and concierge services as well as emergency or vehicle repair services. For details => Audi Telematics by OnStar(R) Owner's Manual.

During events where the Airbag Control Module (J234) processes a crash signal, the vehicle emergency flashers are activated and the doors are unlocked via the comfort/convenience system. In addition, the Telematics system automatically places an emergency call to the OnStar(R) call center.

Telematics hardware includes the driver operated Telematics Control Head (E264) (which contains the OnStar(R) control buttons and system status light) in Front Interior Light (W1), Cellular Telephone (R54), microphone, backup loudspeaker, roof-mounted GPS/Cellular antenna and Telephone/Telematic Control Module with supporting software.

An emergency (back-up) battery for the Telephone/Telematic Control Module is also used in case the vehicle battery goes dead or becomes disconnected due to accident, impact etc.

An Audi-Motorola Digital Telephone (Telephone/Telematics Control Module (J526)) is available as an option in conjunction with the Telematics system.

Telematics functions are performed via the Telematic Control Head (or Digital Telephone handset where applicable). Information can be displayed on either of the Multimedia Interface (MMI) displays. The system is also capable of speech recognition.

Before troubleshooting or servicing, technicians must be familiar with all Telematics functions, operating specifics and the particular service plan which the customer subscribes to "Audi Telematics by OnStar(R) Owner's Manual and/or OnStar(R) " Quick Reference Guide" to become familiar with applicable features and functions.

CAUTION!
The Telematics Service Mode must be activated prior to any service procedures that call for disconnecting the vehicle battery, and prior to removal or replacement of Telematics hardware. Deactivate Telematics Service Mode after vehicle battery is reconnected or Telematics hardware is reinstalled => [ Telematics Service Mode, Activating and Deactivating ] Description and Operation.

On Board Diagnostic
