Telematics System

Before troubleshooting or servicing, the technicians must be familiar with the function and operation of the Telematics system.

Additional information. Refer to --> Volkswagen Telematics by OnStar, --> Volkswagen Telematics by OnStar Owners Manual, and --> OnStar Quick Reference Guide.

When performing service work or Fault-Finding, use --> Vehicle Diagnosis, Testing and Information System (VAS 5051) or Vehicle Diagnosis and Service System (VAS 5052) in the function "Guided Fault Finding",.

When the battery is reconnected, check any affected system or component (radio, clock, comfort electrical connection etc..) according to the repair information and/or the operating instructions.

• Do not exchange Telematics Control Modules between vehicles! Each Telematics Control Module has its own coding and an Electronic Serial Number (ESN) unique to the Vehicle Identification Number (VIN) of a vehicle. Based on these data, the vehicle is identified by the Telematics call center and allocated to the respective customer account.

Volkswagen customers with Telematics system are serviced via Telematics call centers connected to "OnStar".

The "Telematics system" is a vehicle-integrated system. Upon customer request, Volkswagen Telematics by OnStar call center can remotely perform or activate vehicle functions.

Among these services there are for example: traffic jam information, directions, touristic information or the possibility to activate a towing service. This information is made available on driver's demand, depending on the range of services offered by the Telematics call center.

Telematics system can also be controlled by voice, additional information. Refer to --> Owner's Manual.

The following functions can also be activated remote-controlled on customer's demand via Telematics call center:

• Lock vehicle

• Unlock vehicle

• Switch on hazard warning lights of vehicle

• Switch on horn of vehicle

If airbag is deployed during a crash, this is registered in Telematics control module, hazard lights are automatically switched on and all doors are unlocked via door control modules. In addition, an automatic emergency call is placed to the Telematics call center. The center will then try to communicate directly with the driver and discuss and arrange rescue measures. If the driver does not answer to the call made by the Telematics center, measurements for rescue are started automatically by the Telematics center.

The position of the vehicle is determined by GPS technology. Thus, the Telematics call center assistant can locate the current position of the vehicle.

The GPS receiver is integrated in the Telematics Control Module.

Communication between the driver in the vehicle and the Telematics call center takes place via telephone; its sender and receiver are also integrated in the Telematics Control Module.

Triplex antenna is used here.

Troubleshooting

Telematics Control Module is capable of self-diagnosis.

When performing Fault-Finding, use Diagnostic Operation System (VAS 5051) or Vehicle Diagnosis and Service System (VAS 5052) in the function "Guided Fault Finding ".
