Note for development: May have been fixed with commit 327c5147fa0ad543fb6948f0062cac9c931ab2ce

The complaint was observed on 3.1.20 … cannot say what version the commit string means.

Best Wishes,

In 3.1.20, the test for "was erased" didn't correctly include the "if engine model year less that 2019 ignore the misfire test". So, the failure for "erased DM5 data" was incorrectly reported, even though the previous was erased (except for the misfire) and current was erased.

It was fixed as part of https://github.com/Equipment-and-Tool-Institute/j1939-84/issues/1246
