Mainly I need to post here for any perspective on checking these boxes off for corrections, but I also need a place to keep my thoughts as I work through this as well.
For the past few weeks I've been doing some work on the car. This started as a new suspension and bushing project, which turned into a RMS replacement and clutch. The one thing I neglected to do was to measure the before ride height on the EMD springs, to try and get to a similar height with the coilovers. But really, I wanted a little higher height than what they offered anyways.
I put new Bilstein DCC coilovers on, offset bushings on the front LCA's, and bushing in the rear trailing arms. The subframe was pulled, and then transmission for the clutch. The steering rack was left in the car, attached to the hubs, and secured from dangling during everything else. The battery was left on a tender for the duration in order to maintain it's charge. I rechecked all the plugs aside from those in the wheel wells to ensure nothing was missed, and nothing was.
Here's the list of current fault codes:

The engine code is the O2 sensor, guess I'm not sure which one, but if I remember right this is always present with the Stage 2 tune.
My thoughts are most of these are connected, not a matter of multiple issues, kind of. I'm thinking there might be something with the one of the front wheel sensors, maybe with all the fighting on getting the damn hub to slide onto the new strut body. Even with the axle out, this was a royal hassle. I did some real time monitoring though, and each sensor was reading speed, although the fronts had errors on the air gap section. Not sure what that means.
Here's my plan of attack in order listed.

Not sure what that means.
- The ACC I'm sure is due to the ride height being different that it was before.
- The parking assist error I'm guessing is tied to the brake errors.
- The brake errors are saying steering angle sensor, so I'm guessing because the rack was touched, and the steering wheel is a little crooked now, that has something to do with that.
- The driver assistance error I'm sure is connected to everything, because it needs all the inputs for the corner lights, the braking, all the other features.
- I'm guessing the traction control light, ESC light is tied with the wheel sensors?
Here's my plan of attack in order listed.
- Check the front wheel sensors, and their connections, and essential any electrical connector within the wheel wells.
- Work on leveling the ride height first. I'm not sure there's anywhere in East Idaho to do corner balancing, and I really never thought of that much as it's a daily, with autocross duties.
- With the ride height set, then I can work on the ACC alignment.
- I have the alignment scheduled for Friday, once that is done then I can work on the steering angle calibration.
- Hopefully I didn't jack the rack up some how to where it's damaged. All the plugs are intact and connected. I never touched them.
- All those dumb Databus errors.... No clue. Hopefully the big issues being read clear them up.
