The P1A03 and P1A04 are the result of something else going wrong. Sounds like you had a communication error that caused the shutdown, most likely multiple events dealing with your "driveway event". Alot of DTCs take 2 key cycles or 2 warmup cycles to reset. I have this reset problem from time to time when I disconect my scan tool from my FEH and dont follow the exact procedure for shut down.
