Vehicle tracking, general
The vehicle tracking function is also known simply as tracking. It is activated by one of the two following triggering variants:
- Vehicle theft report and legitimization of the customer by telephone at the service center
- Anti-theft alarm system (ATA [EDW]) (with code (FZ5) Anti-theft alarm system (ATA [EDW])) is active for t > 30 s
Vehicle tracking function sequence
The emergency call system control unit activates the GPS position finding and also the voice connection to the vehicle, if necessary. Next, the communication module that is integrated in the emergency call system control unit transmits the position data to the service center.
The position data is transmitted cyclically and for the following events:
- A certain distance is exceeded (is set by the service center)
- Circuit 15 On or circuit 15 Off (ignition switched on or off)
- Damage or tampering to the vehicle detected, if anti-theft alarm system (ATA [EDW]) is activated
The service center forwards the location of the vehicle to the responsible command staff (e.g. police). The command staff can then decide whether to listen in or talk to the driver.
Vehicle tracking can only be deactivated by the service center.
If the telephone and fax antenna (A2/22) malfunctions (e.g. defective because of a rollover), the emergency call system control unit automatically uses the emergency call antenna (A2/52) to receive and transmit the initiation command or the "ATA [EDW] alarm".
