2016 Freightliner Cascadia Evolution. When turning key over for its cycle the red triangle pops up along with check ECAS. It Never happens while driving only on startup. I have turned off and recycled sometimes back to normal quickly other times I play with the load transfer cancelling it and lowering suspension, re raising it. After a few times sometimes a lot it will correct. Also, I lose my rpm/mph gauges although still drivable with a noticeable difference in the ride. Not much info online. Maybe sensor, or leveling valve? Help with any feedback is appreciated!
