Ride height with AlfaOBD (air suspension)

[Bootsy1968]

I have a 2018 Ram 2500 with rear air suspension. Does anyone know how to calibrate the sensor for the rear air suspension. Thanks

Nine leans 1/2" on the passenger side

I input the measurements in millimeters into the ride height setting...
I tried everythig in the alfaobd menue on suspension module and nothing helped. It can be commanded via alpha obd into off road 2 and after doing so can be switched back and fourth from off road 1 to 2 a few times but then it goes back to selected ride height unavailable due to payload error. The component air mass / pressure / ride height readings diagnostic does not work it just doesn't do anything. Not sure if it's supposed to work? Anyway these offsets look bizarre to me.

I'm having the exact same problem as you, did you ever figure out the issue?

Hey guys, I made a quick video for how to write suspension values with AlfaOBD on my 2016 Ram Rebel. Here it is:



Hope this helps everyone!

I just replaced compressor and valve block. Refilled tanks with 175psi nitrogen. Now with truck sitting on all 4 bumpstops when I try to add air to bags with alpha obd nothing happens. When I do conpressor check I can hear compressor cycling. Just no air going to bags. I keep getting low air mass code and plant mode. It won't let me set ride heights with obd. I have service air suspension on dash and all adjustment button lights are flashing.
Any suggestions on a fix would be appreciated.
