It seems that the emissions Gods want to frustrate me anytime I start a journey. Yesterday I had Fault Codes 3567 FMI 5 SPN 5394 Aftertreatment Diesel Exhaust Fluid Dosing Valve - Current below normal or open circuit; 1682 FMI 31 SPN 3362 Aftertreatment 1 Diesel Exhaust Fluid Dosing Input Lines - Condition Exists; 3714 FMI 31 SPN 1569 Engine Protection Torque Derate - Condition Exists,
Using Cummins Insite, I did the "Aftertreatment Diesel Exhaust Fluid System Leak Test" It held 130 PSI with no leaks evident. I also did the "Diesel Exhaust Fluid Doser Pump Override Test" which required removing the Doser Valve to watch it spray DEF. Removing the valve was easy, 3 screws with an 8mm socket, 6" extension and 1/4" ratchet. It sprayed OK, I re-seated the electrical plug on the valve & traced the wiring somewhat but didn't see any obvious problems.
Code 3714 will derate the torque and then limit the speed to 5 MPH. It derated to the first level yesterday but I made it to my campsite OK.
Using Insite I cleared the codes and drove 200 miles today with no issues.
