testFailedSinceDTCCleared
This bit shall indicate that a current DTC is or has been set
sometime since the last time the DTC status was reset.
1. Bit set to 1 = Test failed since DTCs have been cleared.
2. Bit set to 0 = Test not failed since DTCs have been cleared.
3. Bit will be set to a value of 0 on a successful code clear.

testNotPassedSinceDTCCleared
This bit shall indicate a value of 0 once the test indicates a
passed result. A value of 1 indicates that the test has not run, or
that the test has run and failed.
1. Bit set to 1 = Test not passed since DTC cleared.
2. Bit set to 0 = Test passed since DTC cleared.
3. Bit will be set to a value of 1 on a successful code clear.

currentDTC
A current DTC shall indicate that test conditions have been met
and the test results show that a fault is currently present. This bit
shall indicate the results of the last diagnostic test performed. A
current code status may span multiple power cycles since it
reflects the result of the last test performed.
1. Bit set to 1 = DTC is current.
2. Bit set to 0 = DTC is not current.
3. Bit will be set to a value of 0 on a successful code clear.

DTCSupportedByCalibration
This bit shall indicate that a node will trigger the test associated
with a particular DTC as soon as the criteria for performing the
test have been satisfied.
1. Bit set to 1 = DTC supported.
2. Bit set to 0 = DTC not supported.
3. Bit is NOT altered by a code clear attempt.

– The intent of these bits is to provide build integrity and repair verification. Deviation from supporting these bits (e.g.,
Hardware limitations) shall be negotiated by service, assembly, and the DRE, and documented in the CTS.
Note: 
If either bit 6 or bit 5 is supported, then the other should also be supported. Also, if either bit 3 or bit 2 is
supported, then the other should also be supported. In other words, bits 6 and 5 should be supported as a pair,
and bits 3 and 2 should be supported as a pair.
