VHMS DATA ITEMS
Fault Codes
The VHMS controller maintains a history of the most
recent 600 fault codes. For each fault code, the
VHMS controller records the following information:
1. Fault Code Number
2. SMR (service meter reading) when the fault
occurred
3. Time/Date when the fault occurred
4. SMR (service meter reading) when the fault
cleared
5. Time/Date when the fault cleared
If a fault occurs more than once within 30 minutes,
the VHMS controller will only maintain a single fault
entry, but will count the number of times the fault
occurred and cleared. This feature prevents an inter-
mittent fault that occurs repeatedly from filling up the
fault memory.
Serious fault conditions will be sent to WebCARE via
the OrbComm satellite network, as well as being
recorded in permanent memory. Some fault codes
are configured to generate a snapshot when they
occur. Refer to Table 6 for detailed information show-
ing which fault codes will send data to WebCARE
and which ones trigger a snapshot.
