Self-test
After activation of the status circuit 15R ON, the emergency call system control unit performs a self-test (approx. t = 3.5 s). After a successful self-test, the TELE AID system is operational.
In the event of a fault or if authorization has not been provided, a fault message is displayed in the instrument cluster depending on the fault type and the two red light emitting diodes in the SOS push button are also permanently actuated. Depending on the fault type, the fault is also stored in the emergency call system control unit's memory.
The TELE AID system consists of the following subfunctions, which are described in separate documents:
- Voice connection to vehicle, function
- Display of TELE AID status, function
- Selecting telephone antenna, function
- Position finding, function
- Emergency call, function
- Vehicle tracking, function
- Breakdown assistance, function
- MB information, function
- Vehicle remote door unlock, function
Prioritizing of supplementary information:
All listed vehicle-related services run automatically in the emergency call system control unit. The emergency call system control unit has a priority management feature to ensure that it does not have to manage several vehicle-related services at the same time. This determines the point at which a vehicle-related service is to be activated and which vehicle-related service has a higher priority. Depending on which vehicle-related service is to be activated, the emergency call system control unit releases resources in accordance with the priority list and activates the vehicle-related service or refuses activation because a vehicle-related service with a higher priority is already active. The highest priority is given to the completion of an automatic TELE AID emergency call.
