Diagnosis

The alarm memory of the USIS stores all alarms except the independent alarm. The alarm memory contains information on initial triggers, as well as subsequent triggers, date, time and environment related conditions (ambient temperature, window and sliding/tilt sunroof position, heating sys etc.).

The alarm termination mode (alarm abort by disarm or expiration) is also registered. The last 10 alarms are stored in a register. The alarm memory is designed to provide sufficient information on alarm trigger mode, time and vehicle condition so that the sources of false alarms can be detected and corrected.

The alarm memory in the emergency siren stores only the data of the independent alarms. The last 5 alarms are stored.
