Note
Use the applicable fault models to ensure a structured analysis. If there are additional fault models needed, please enlarge the list of fault models.
Note
An ASIL related message is trustable in that manner that it is not corrupted, repeated, lost, delayed, masqueraded or addressed incorrectly.

ID
Failure Mode
Importance (can be used for prioritization)
message
MF_01_01
message is not received (is a subset/more precise description of MF_01_05)
High
message
MF_01_02
message received too late (only relevant if delay is a realistic fault)
Medium
message
MF_01_03
message received too early (usually not a problem)
Low
message
MF_01_04
message not received correctly by all recipients (different messages or messages partly lost). Only relevant if the same message goes to multiple recipients.
High
message
MF_01_05
message is corrupted
High
message
MF_01_06
message is not sent
High
message
MF_01_07
message is unintended sent
High
duration/time constraint
CO_01_01
minimum constraint boundary is violated
Medium
duration/time constraint
CO_01_02
maximum constraint boundary is violated
High
execution
EX_01_01
Process calculates wrong result(s) (is a subset/more precise description of MF_01_05 or MF_01_04)
High
execution
EX_01_02
processing too slow (only relevant if timing is considered)
Medium
execution
EX_01_03
processing too fast (only relevant if timing is considered)
Medium
execution
EX_01_04
loss of execution
High
execution
EX_01_05
processing changes to arbitrary process
Medium
execution
EX_01_06
processing is not complete (infinite loop)
High
