Is anybody familiar with Cummins Service Bulletin number 4310705? I have been trying to keep up with after treatment tech to try and keep our fleet on the road. Will keeping the controller software updated help or is this just a waste of time. We have only seen a few of the listed corrections (line heater faults and def leaking from the controller connection) in our scans. Any thoughts?

They would like us to sign our correspondence like that…hehehe
if cummins sends you a letter about an update then it should be done , everything else is just to widen parameters so a code takes longer to come active , sad but true
