Hello, this is my first week out with a Freightliner Coronado 2019 SD122 and connected it to the OTR Performance during my 34 break. I that the soot level percentage was a whopping 250% which surprised me. So I initiated a Forced regen but it didn't bring down the soot percentage unfortunately.. I was wondering if it might be a faulty wire or if the filter needs to be replaced on air drier or dpf?
The attachments are OTR Performance's reading during the Regen.
The truck had the one box replaced at 500,000 miles and it is currently 565,000.. if I could get any help or info regarding this problem, I would really appreciate it!
Thank you very much.

NOTE!: Sorry! The soot level went down to 0% after it finished the regen.. this is embarrasing.. Im unsure how to delete the post since it is no longer an issue..
Forced Regen but Soot Level high
