There’s an issue with the Insite program that’s supposed to perform diagnostics on the cylinder section. The program is simply blocking the test, and there’s no clear reason why.󠄐󠄹󠅀󠄪󠄡󠄨󠄞󠄢󠄢󠄥󠄞󠄩󠄢󠄞󠄡󠄨󠄬󠅒󠅢󠄟󠄮󠄐󠅅󠄹󠄴󠄪󠄾󠅟󠅤󠄐󠄼󠅟󠅗󠅙󠅞󠄬󠅒󠅢󠄟󠄮󠅄󠅙󠅝󠅕󠄪󠄡󠄧󠄤󠄦󠄠󠄠󠄥󠄦󠄥󠄢󠄬󠅒󠅢󠄟󠄮󠇖󠅸󠆁󠇗󠅸󠆡󠇘󠆭󠆖󠇖󠆄󠆩󠄐󠇗󠅹󠅸󠇖󠆍󠅳󠇖󠅹󠅰󠇖󠆌󠅹󠄬󠅒󠅢󠄟󠄮

The original ECM, with the cumimins insite software, didn’t resolve the issue. Recently, Cummins replaced the ECM with a new unit, but the cylinder neckline test is still blocked.
