CLK 550 Cabriolet (209.472) V8-5.5L (273.967) (2007)
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.
