Treatment of fault
After activation of circuit 15R, the emergency call system control unit performs a self-test (for approx. t = 4 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 fault
type, and the two red light-emitting diodes (LED) in the emergency call system button are permanently actuated. Depending on the fault type, the fault is
also stored in the emergency call system control unit's memory.
