Just tried to reflash my ecu after getting it back from the dealership and noticing it had been flashed. Tried to install autocal but code $0312 comes up. Tried to reset back to stock but same error code pops up. Truck is dead in the water now. Any information will be helpful.

Unplug your csp switch

It worked. Thanks. Didn't even think about the switch being the problem.

Code 0280 keep popping up, truck looses power after about 300 miles, clear code runs good again?????

Does your post have anything to do with what this thread was originally about given what this fault code is and being a Cummins.
FYI - P0280 Injector Solenoid Driver Cylinder #7 Current Too High
