Treatment of fault
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, a fault message is displayed on the instrument cluster, depending on the type of
fault and the two red light-emitting diodes (LEDs) in the SOS pushbutton switch are actuated continuously. Depending on the fault type, the fault is also
stored in the emergency call system control unit's memory
