yep even though no cel there is still a code.
fail safe is described as a safe driving mechanism to let you take your truck to a trans shop because there is something wrong with it or wiring.
fail safe and limp are two different things though. what you describe is he has both.
limp mode is the engine, fail safe is for the trans. there is a number of things for the engine that can throw it into limp.
should try the ecu reset and if problems persist i would take it to a dealer.
