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

Telematics, technical features

Telematics is an in-vehicle communication system that uses 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 Telematics/Telephone Control Module 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, see AUDI TELEMATICS BY ONSTAR(R) Owner's Manual.

During events where the Airbag Control Module processes a crash signal, the vehicle emergency flashers are activated and the doors are unlocked via the respective door control modules. 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 (which contains the OnStar(R) control buttons and system status light), microphone, backup loudspeaker, roof-mounted GPS/Cellular antenna, Telematics/Telephone Control Module (with supporting software) and related wiring.

An emergency (back-up) battery for the telematics control module is also used in case the vehicle battery goes dead or becomes disconnected due to accident, impact etc..

All telematics components are factory installed/integrated into the vehicle electrical system.

Contact Corrosion

To minimize contact corrosion, only use approved fasteners (screws, nuts, bolts, washers etc.)

Where applicable, fasteners may have a special surface coating recognizable by a greenish color.

Coated fasteners must also be stored separately.

On Board Diagnostic (OBD)

The telematics system has extensive On Board Diagnostic (OBD) capabilities.

The Telematics/Telephone Control Module has a Diagnostic Trouble Code (DTC) memory. If a malfunction occurs in one of the components or wires which is monitored by the system, a record of the type of malfunction is stored in DTC memory.

Perform OBD program using VAS 5051 Vehicle Diagnostic, Testing and Information System in mode "Vehicle Self Diagnosis" and/or "Guided Fault Finding".

Telematics Control Head - OnStar(R) controls

The Telematics Control Head is integrated with the front interior light module. The control head contains three separate buttons as well as a system status indicator light (LED).

The OnStar(R) ("On*") button is used to contact the OnStar(R) call center to request various convenience services. It is also used to initialize/activate the owner's subscription to OnStar(R) services and/or update the customer's account in the event that the Telephone/Telematics Control Module requires replacement.

The Emergency button is used to contact the OnStar(R) call center to request emergency services such as fire department, police etc.

The Communication ("DOT") button is used to end a call to the OnStar(R) call center, place or answer personal calls (in conjunction with the optional digital cellular telephone), or cancel a call if one of the other buttons is accidentally pressed.

Note. Use of certain OnStar(R) services requires a subscriber's Personal Identification Number(s) (PIN).

For complete system operation details, see AUDI TELEMATICS BY ONSTAR(R) Owner's Manual.

Telematics Control Head - OnStar(R) system status light

The system status light is located between the Communication and Emergency buttons. The green light comes on after a self-check routine is performed (approx. 10- 15 seconds after ignition is switched on).

Indicated conditions

1. Green: Indicates system has passed self-test and is ready to place or receive calls. Light remains on even in areas without cellular coverage.
2. Blinking green: Indicates a call has been initiated or is in progress.
3. Red: Indicates system has not passed self-test or indicates system malfunction.

Note. System troubleshooting using system status light, see TELEMATICS SYSTEM, TROUBLESHOOTING USING ONSTAR(R) SYSTEM STATUS LIGHT .

OnStar(R) Personal Calling

An optional digital cellular telephone with specific features integrated into the telematics system is also available.

OnStar(R) and OnStar(R) Personal Calling are activated separately.

Note. Use of certain OnStar(R) services requires a subscriber's Personal Identification Number(s) (PIN).

For complete system operation details, see AUDI TELEMATICS BY ONSTAR(R) Owner's Manual.
