testNotPassedSinceCurrentPowerUp
This bit shall indicate a value of 0 once the test indicates a
passed result. A bit value of 1 indicates that the test has not run,
or that the test has run and failed. This bit shall be reset to a value
of 1 with each ignition cycle.
1. Bit set to 1 = Test not passed since current power up.

historyDTC
A history DTC indicates that a current DTC status has met
sufficient criteria for storing a code into long term memory.
Sufficient criteria may consist of a current status detected over a
span of time or over multiple test cycles.
If DTC criteria to activate a warning indicator are satisfied, then
the DTC history bit shall be set to a value of 1 and the DTC status
must be stored to long term memory.
1. Bit set to 1 = DTC is history.
