Good day

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?

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
