The tested bits allow the distinction between a a case when a fault bit is not set because the fault is not detected,
and the case when a fault bit is not set because the diagnostic test has not completed. For instance, the calculated
duty cycle is too low to complete the short to battery test.
Two fault tested bits are defined:
The tested bit is set to 1 when the fault test has completed successfully.
