C1726 2007 Expedition
I am getting the code C1726 (Air Suspension Rear Pneumatic Failure)-- I have done various trouble shooting. Neither of the Two Leveling devices are bad. I have removed the Airlines from each bag and with a bit of running back and forth to turn the key on and off and close the door I have inflated both with external air and neither seem to have leaks. I have uncoupled the leveling arms and confirmed the control module does recognize vehicle height and it demand the pump at various positions. I blow a little pressure (10-20psi) in to the vehicle air line and it appears to hold but when I apply suction it doesn't. Anyone have any experience with typical failures on these systems? I suspect the compressor is bad and unable to build pressure as I can hold my finger over the hose when the compressor is running. Any feedback is appreciated!!

Update:
after monkeying around with it most of yesterday I have finally determined its the compressor. I manually inflated both bags and disconnected the solenoids at each air-bag just to be sure I didn't have a bag leaking. As of now both bags are completely inflated with no change in vehicle level. New compressor to arrive Wednesday Oct 30th and will be installed shortly after. Lowe:-jammin |
