The quality of this work is pleasant.
Will wait on CI. Will review the implementation against the standard tonight.

Do you need it released right away? Or do you plan on making additional PRs?

[jacobs-rvw]

If possible sometime later this week. I'm checking with the team to see if there were any other issues we're looking to resolve but for the time being this is the main one. I'll check the CI results in a bit. It didn't seem immediately obvious what the failure was.

[pylessard]

just restarted ci. venv creation failed.. I don't think it's coming from you.

[pylessard]

Possibly this : 9ff5f4a

I think my master branch was passing because it was reusing a venv created previously.
I fixed the master branch. You can merge or rebase your PR.

Don't forget to remove the debug prints

[pylessard]

I will leave this here. It's a change made in setuptools.

Can you add constants to define the common values of FunctionalGroupIdentifiers. There seems to be only 3 value defined.

Emissions-system group : 0x33
Safety-system group: 0xD0
VOBD system: 0xFE

You can add a class inside common/dtc.py So we can have Dtc.FunctionalGroupIdentifiers. Inside your method docstring, you can mention that the values can comes from :class:`Dtc.FunctionalGroupIdentifiers<Dtc.FunctionalGroupIdentifiers>`

Finally, add an autoclass in doc/source/udsoncan/helper_classes.rst. Sphinx will connect your docstring to it automatically.

I updated the docs. Let me know if there's anything else. I'd like to squash and reword once you're happy. I need to validate a few things tomorrow but the unit tests look ok to me and I think the ergonomics are improved.

Thanks for the help.

[pylessard]

Will do a final check later.
I only do squash-merge btw, so do 't worry too much about the history

[pylessard]

You have my 2 final comments.
Call the shot and I will merge.
Let me know iwhen you need the release. It takes less than a minute to make

@jacobs-rvw If possible could you add support for report wwhobd dtc with permanent status?

[jacobs-rvw]

@pylessard - I resolved those two findings, squashed and cleaned up. Tested again and it seems to meet the our needs. If you can merge/release this week it would be appreciated. Thanks for the help.
