After the aformentioned tests I ran two attempts from l to n, neither managed to get to n. Here is the data after each failed attempt.

If your pump is not working each time, guaranteed, then you'll want to address this first. Every time you crack a bleed valve and you run the motor, do you get fluid out? If so your pump is probably ok.
Since you answered intermittent.pump operating.. I would disconnect the battery. Remove the electrical connector from the height accumulator. Inspect for wetness chaffing etc. Clean and reinstall. Remove and inspect each electrical connection at the pump and pressure sensor. While the power is still disconnected at the battery open the accumulator bleeder then when fluid stops completely carefully slowly remove the bleeder screw completely and clean and inspect it for clogging. Reinstall bleeder screw.
Also take lots of pictures of the pump height accumulator, each sensor, globes etc.
Report back before battery reconnecting.

Reporting back. Everything looked good. Wires good. Cleaned out all connectors with cleaner and compressed air. Should come to no suprise given what I have said before but I did not get a drop of fluid from the accumulator when I removed the bleeder. A little messy with AHC fluid and PB blaster in the vicinity. I hit each bleeder with PB blaster about a half dozen times before I started this adventure, I tried to clean up things before shooting the pics.

So you get no fluid from the height accumulator and the bleeder was not clogged?

Reconnect battery. Have someone start the truck while listening at the pump. Turn off truck. Report back.

Correct, not a drop from the height accumulator and the bleeder was not clogged.
See last post. If you hear pump running when it stops shut off the truck and report back -prepare to reconnect to techstream. If no pump noise shut off the truck and report back. Prepare to check continuity at height accumulator.

It seems the pump sounds fine although fluid level is not changing. Let's look at the data. Ok looks like you are on bumpstops front and rear try the up button to neutral report back with another datalist photo.

First photo is as instructed. Second photo is after codes were cleared and second attempt from l to n.
What were the codes?
