If the FMI used is anything other than one of those in the table above, then both the
low and high faults will be assigned the same FMI. This condition should be
avoided, as the log will still used different OC for the two types of faults, even
though they will be reported the same in the DTC.
It is the user’s responsibility
to make sure this does not happen.
