I'm working on a 2010 Mack MRU non-cat dpf system with SPN 3485 FMI 7 code for the atomizing air control module. I can run through the test procedures with PTT and the code will go inactive but then it returns. Has anyone worked with this system much that might have any ideas? I've tried a used module but gave same code.
