Hmm.. take this the right way but... are you following the EAS software instructions correctly with regards establishing coms with the ECU ok before reading faults?
a) Can you do a screen shot?
b) what are your height settings (Access, highway, std, high and ext) for each corner as per the software tab via Get values?
c) Clear the faults, then re plug in...set the vehicle at each height setting and check that the height your vehicle telling you makes sense to that of the stored programmed values (bottom of the EAS tab on that screen).
