Self-test
After activation of circuit 15R, the emergency call system control unit performs a self-test (for approx. t = 3.5 s). If the self-test is successful, the emergency call system is then ready for operation.

In the event of a fault or if authorization (provisioning) has not been provided, a fault message will be displayed in the instrument cluster (A1) depending on the fault type and the two red light-emitting diodes (LED) in the emergency call system button (S93/3) are also permanently actuated. Depending on the fault type, the fault is also stored in the emergency call system control unit's memory.

General
The emergency call system control unit enables the following vehicle-related services to be realized:
- Authorization
- Emergency call (E-Call) manual or automatic, including police emergency call number "911"
- MB-Info call
- Breakdown assistance (Roadside Assistance)
- Tracking

^ Data from restrain systems control unit
^ Vehicle remote unlocking
^ Vehicle remote locking
^ Position finding
^ Roadside assistance

Prioritization
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 the 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. Automatically completing an emergency call has the highest priority.
