time to scan for data link failure codes and see which computers are still on line and which are non responsive, might be a simple fuse or chaffed wiring causing communication failure. i find if all the computers ecm, pcm, abs, and icu are not on a constant confrence call with each other the vehicle will enter limp mode.
