- with CODE (359) TELE AID emergency call system

Function requirements
^ C. 15R On
^ Communication with the supplemental restraint system control unit (N2/10) operating error-free
^ Automatic crash detection including "crash level" by supplemental restraint system control unit

Data from the supplemental restraint system control unit, general
In the event of an accident with airbag deployment, an automatic emergency call is transmitted immediately. An emergency call is sent out regardless of the severity of the accident.

Function sequence, data from the supplemental restraint system control unit
The emergency call system control unit (N123/4) receives the crash data from the supplemental restraint system control unit via a direct line as a digital crash signal on the one hand and, on the other hand, it also receives the data (redundantly) including the crash level via the following route:
- Chassis CAN (CAN E)
- Front SAM control unit with fuse and relay module (N10/1)
- Diagnostic CAN (CAN D)

The supplemental restraint system control unit transmits a "LIFE" signal (supplemental restraint system control unit "sign of life") via the same route as the crash information including "crash level" every t = 500 ms.

This allows the emergency call system control unit to permanently monitor communication with the supplementary restraint system control unit and proper function of the crash detection.
