Cummins ISB 6.7 5655 code pops up, often. We checked everything that insite told us too. Could contamination of the def fluid cause code 5655...scr conversion condition exist.
If you checked ALL the systems put the esn in qsol to be sure there is not a campaign on the scr brick. And check calibration revisions. We just had a unit that was failing the scr brick and a calibration update corrected the issue
I'm a seasoned mechanic but i recently got a job as a diesel mechanic. These are helping a ton! Thank you!
Your videos are really detailed. So much to learn from . Any tips for troubleshooting faults for nox sensor and PM sensor .

Thanks joe
