General Information 

 

  

   Telematics is an in-vehicle communication 

system that uses cellular 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 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 Volkswagen 

customers are provided by OnStar

 via a 

dedicated call center. Service plans may 
provide route directions and concierge 
services as well as emergency or vehicle 
repair services. For details

Module processes a crash signal, the vehicle 
hazard lights are activated and the doors are

automatically places an emergency call to 
the OnStar

call center.

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. OBD
