GF82.95-P-3005GQU Restraint System Control Unit Data, Function
- with CODE (359) TELE AID emergency call system
Function requirements
^
Status "Circuit 15R ON"
^
Proper communication with restraint systems control unit (N2/7)
^
Automatic crash recognition including crash level by restraint systems control unit
General
In the event of an accident with airbag actuation, an automatic emergency call (E-Call) is transmitted immediately. An emergency call is sent out
regardless of the severity of the accident.
Function sequence
The emergency call system control unit (N123/4) receives the crash data on the one hand via a discrete line as digital crash signal from the restraint
systems control unit and, on the other hand, of the following (redundant) path, including crash level:
-
Engine compartment CAN
-
Central gateway control unit (N93)
-
Diagnostic CAN
The restraint systems control unit sends a LIFE signal (the LIFE signal is the "life sign" from the restraint systems control unit) every t = 500 ms over the
same path as the crash information including crash level. This allows the emergency call system control unit to permanently monitor communication with
the restrain systems control unit and proper function of the crash recognition.
