Starting to think that the problem exists in the software installed during an ecm flash. Has anyone had a 1223 code prior to an ecm flash?

Solved my problem. The 1223 code progressed to a 0148 high pressure common rail. Took the valve cover off and started the engine; the number 4 injector was leaking. Replaced the injector, no more codes.
