Emissions Light and Torque Derated Coach 1482
#1

Had the Engine light and Emissions light come on and the torque immediately derated.  This is the Def problem where it does an initial derate and then if you keep driving it will eventually derate to 5 MPH.  I made it to the campground and using Cummins Insite was able to clear the codes but haven't resolved the problem.

Cummins ISX CM2250
Codes 3258 FMI5 SPN4340, Aftertreatment 1 DEF Line Heater 1 Circuit Current below normal or open circuit
3261 FMI 5 SPN 4342 Heater 2 Circuit same detail
3425 FMI 5 SPN 4344 Heater 3 Circuit, same detail
3714 FMI 31 SPN 1569 Engine Protection Torque Derate

edit to reflect current status. The auto reset DEF Line Heater fuse is in the engine compartment fuse box, it checks good but I changed that fuse to a normal fuse.  Line heaters ohms check good.  Could be caused by a bad DEF Controller also.  Travelling today........

Suggestions?
