FMI=19—RECEIVED NETWORK DATA IN ERROR
Any failure that is detected when the data received via the network is found substituted with the "error indicator" value (i.e. FE16,
see J1939-71). This type of failure is associated with received network data. The component used to measure the real world signal is
wired directly to the module sourcing the data to the network and not to the module receiving the data via the network. The FMI is
applicable to Region f and g of the signal range definition. This type of fault may or may be directly associated with the value of general
broadcast information.
FMI=20-30—RESERVED FOR SAE ASSIGNMENT
FMI=31—CONDITION EXISTS
Used to indicate that the condition that is identified by the SPN exists when no more applicable FMI exists or in cases when the
reported SPN name spells out the component and a non-standard failure mode. This type of fault may or may be directly associated
with the value of general broadcast information. This FMI will mean "not available" when the associated SPN is also "not available" as
when the remainder of the packet is filled with binary ones after all data has been transmitted.
