GF82.95-P-3005QM Restraint System Control Unit Data, Function
- with CODE (359) TELE AID emergency call system
The emergency call system control unit (N123/4) receives the following messages via a direct digital crash signal from the restraint systems control unit
(N2/7), and also (redundantly) via controller area network (databus/CAN bus) (CAN) diagnosis from the EIS control unit (N73). The EIS control unit
(N73) receives the message via Controller Area Network bus class B (interior) (CAN-B) from the restraint systems control unit (N2/7):
Crash data on CAN diagnosis
Byte No.1
Byte No.2
The crash is automatically detected by the restraint systems control unit (N2/7). The emergency call system control unit (N123/4) receives the crash
information via a direct digital crash signal from the restraint systems control unit (N2/7), and also (redundantly) via CAN-B from the EIS control unit
(N73). In the event of an accident, an automatic emergency call is made immediately. This occurs no matter how severe the detected accident actually is.
Error messages
The restraint systems control unit (N2/7) transmits a Life signal every 500 ms. Thus, the emergency call system control unit (N123/4) is informed about
the proper operation of the crash detection system.
The restraint systems control unit (N2/7) cyclically performs a self test. A fault in the system is indicated by flashing red LEDs in the SOS pushbutton
switch (S93/3) in normal operation. The corresponding fault message (status message) is displayed in the display of the COMAND operating, display
and control unit (A40/3) and in the multifunction display (A1p13) of the instrument cluster (A1). The red LEDs remain active until either circuit 15 is
switched off or the error is rectified. The SOS pushbutton switch (S93/3) is monitored. A stuck SOS pushbutton switch (S93/3) is detected. False signals
are ignored and the system remains operational.
