Got the "SELF LEVL INACT"

Was hoping I'd get lucky and my ELM style bluetooth OBD2 scanner and torque app would be able to tell me the real fault code so I could see what sensor was bad or get a clue as to the malfunction..no such luck it reads nothing for this.

I checked the ride height level sensors..nothing obviously wrong. The dog bone is plastic and there doesnt seem to be play..the arm on the sensor moves if you jounce the truck around, as it should.

Back end seems level..according to a 4 foot level and measuring tape. No ride quality difference noticed.

I've been meaning to get a DIY GT1 or MODIC, DIS, etc.. scanner going. Looks like there is lots of info all over the internet on how to get this up and running, but I'm not sure which would be the most appropriate.

I've also considered just getting someone to read the code out for me, and then I will fix whatever is wrong and they can then clear it and calibrate the ride height system. I dont want the dealer or anyone else working on my X5.

Any advice on diagnostics I can do myself?

Anyone know what sort of output the ride height sensors have? I have a digital scope and other test equipment and maybe I can take them out and test them myself to see if they are good or not.

I'm assuming that at some point in this process someone will have to clear the fault code and do the calibration no matter what to get rid of the error and make things work properly..right?

Thanks for any help!
