GF82.95-P-2021LEU Vehicle Tracking, Function
- with CODE (359) TELE AID emergency call system

Function requirements
^ Circuit 30
^ Emergency call system authorized and operating properly
^ The vehicle-related vehicle tracking service is authorized separately
^ The customer is registered and authorized at the service center
^ One mobile phone network is available in sufficient strength and quality

General
The following points are vehicle tracking objectives:
- Retrieval of stolen or misappropriated vehicles
- Fast assistance in the event of "car jacking"

The vehicle tracking function consists of the two following subfunctions:
^ "Theft Alarm" function sequence, with code (551) Antitheft alarm system (ATA)
^ Function sequence for vehicle theft telephone message from customer to police and then to service center
^ "Tracking" function sequence

"Theft Alarm" function requirements, with code (551) Antitheft alarm system (ATA)
^ Anti-theft alarm system (ATA) active for > 30 s

"Theft Alarm" function sequence, with code (551) Antitheft alarm system (ATA)
If the anti-theft alarm system is triggered, the emergency call system control unit (N123/4) receives an "ATA alarm" message via the following route:
- Rear SAM control unit with fuse and relay module (N10/2)
- Interior CAN
- Central gateway control unit (N93)
- Diagnostic CAN

The "ATA alarm" message is transmitted by the communication module integrated into the emergency call system control unit to the service center via the following route:
- Direct line
- Frequency switchover control unit (N96), model 221 with code (389) Mobile phone preinstallation with universal interface, USA/Canada
- Emergency call antenna (A2/52), model 216
- Telephone and GPS roof antenna (A2/49), model 221

The emergency call antenna is integrated in the GPS antenna (A2/49a2) in model 216.

The service center receives the "ATA alarm" message and advises the customer by telephone that the ATA alarm has been triggered. "Tracking" will not yet be accomplished by the service center.

Function requirements for vehicle theft telephone message from customer to police and then to service center
^ Customer has been notified about the activation of the ATA [EDW] alarm by the service center
^ Customer notices that vehicle has been stolen

Function sequence for vehicle theft telephone message from customer to police and then to service center
If the customer has been informed by the service center that his vehicle has been stolen or if the customer himself notices that the vehicle has been stolen, it is first necessary for the customer to report the theft to the police. The customer receives a special number from the police, which confirms that the vehicle theft has been reported.
With this special number, the customer can report to the service center, by telephone, and give this special number to the employee there. The service center checks the request and legitimation (authorization) of the customer.

"Tracking" function requirements
^ Vehicle reported as stolen by customer, by telephone, to police and then to service center as well as legitimation (authorization) by service center
^ An emergency call system control unit communication module authorized for the corresponding vehicle-related service is configured ex-factory with the telephone number of the corresponding service provider
^ A higher-priority vehicle-related service is not active
^ No faults in Global Positioning System (GPS) antenna system and signals present from at least 3 GPS satellites

"Tracking" function sequence
After reporting the theft to the service center and legitimation (authorization) by the service center, an initiation command is sent to the vehicle.
The initiation command is received by the communication module integrated into the emergency call system control module via the following route:
- Emergency call antenna, model 216
- Telephone and GPS roof antenna, model 221
- Frequency switchover control unit, model 221 with code (389) Mobile phone preinstallation with universal interface, USA/Canada
- Direct line

The emergency call system control unit then activates the GPS position finding and also the voice connection to the vehicle. Then the communication module integrated into the emergency call system control unit sends the position data to the service provided in the same manner as the "ATA alarm" message.

The position data is transmitted cyclically and for the following events:
- When a specific distance is exceeded
- Recognition of damage or manipulation to the vehicle
- Status "Circuit 15 ON" or "Circuit 15 OFF" (ignition switched on or off)

The service center forwards the location of the vehicle to the responsible command staff (e.g. police). The command staff can then decide whether or not to speak to the driver.

Vehicle tracking can only be deactivated by the service center.

If the telephone and GPS roof antenna, model 221, or the emergency call antenna, model 216, fails (e.g. malfunction caused by rollover) the emergency call system control unit transmits and receives the mobile radio signals and data via the following route in order to transfer mobile radio signals and mobile radio data:
- Direct line
- Emergency call system antenna splitter (A2/25)
- Direct line
- Emergency call system left backup antenna (A2/54)
- Emergency call system right backup antenna (A2/55)
