Suspension problem
2004 Lincoln Navigator V8 Four Wheel Drive Automatic

Hello, I am an interprovincial licensed mechanic in Ontario Canada (near Toronto). Fault code c1725 and c1726 for front and rear " AS" faults, replaced both front and the rear sensores, claered codes and sent to locale dealer for " recalibration" and ride height-trim to bet set. Vehicle came back too low in front ride height. Fault code c1725 front " AS" fault reset. Front sensors are mounted on the correct sides and links still connected. Sent vehicle back to have the ride height trim in front reset closer to a more level trim, vehicle came back, now trim heights good BUT c1991 calibration module fault will not clear, did dealer " kill" module, pump runs, " check air suspension" illuminated on " DIC" Using Snap-On MODIS and soon to be with a J2534, but a little stumped, Anyone have an idea?
