First, you can actually just ignore the 603. What it's saying is, that at sometime in the recent past, the PCM went unpowered (pull it, a fuse, or battery, you get that). Aslo, the 541 isn't anything to worry about either (the AIH isn't even necessary).
The two that are
significant, are the 1316 and the 1211.
The 1316 is an IDM code alerting you to the fact that the IDM sees something wrong with the electrical control of the injectors (most often you'll find they aren't all firing, commonly, a whole side) and it needs to have you perform a Buzz Test
on it to enable the IDM to narrow the problem down (you'll need a better piece of equipment to do a buzz test than a code reader)
The 1211 is about HiPres oil. There are Many reasons for you to get a 1211 and it too will require better equipment to help you diagnose and narrow down. Start with the basics, monitor the ICP pressure and IPR %. I don't much about your Edge, BUT because tuning often puts those HiPres values out-of-spec, for performance gains, it is not uncommon to have the 1211 get set and not have a real problem.
SO, if you feel like you've lost 1/2 the cylinders, that's where I'd start. You well may have. If you check for heat in the exhaust manifolds, compare the two sides, you can often find the "dead" side (sometimes it's just a matter of feeling them). Check the UVCH plug on the bad side carefully. If it's OK, follow the wiring from it back to the IDM for signs of chafing against things (valve covers and the like) and then suspect the IDM itself (which, because of its location, can get water in it)
