Stallyn thank you for the response. I got the actuator to install and calibrate in insite because the cummins insite I had installed for quite some time on my laptop was out dated, with 7.5 version and not 7.6+ version.. I took out the scr and def filters, the second one seemed to be cracked and might be causing my problems..
Can 0125 fault code be in anyway related to aftertreatment problems? Or am I looking for two separate problems?
