RE: unknown DTC
what make/model truck?. What make/model engine?.
some history?.

Also 3597, fmi2 is usually the code for power lost with ignition still on.


Could be wiring issue .. or of it is a CM570, CM8670, or CM871,.. could be the ecm going bad due to no one ever bothering to change the crank shaft damper when it was supposed to be and now excessive vibration causing damage to the ecm.
here is some related info (about mid-way onto this post):
