I can't seem to find anything on the forum (must be searching wrong). I need to deflate the air suspension system in order to replace the front air shocks. My Chilton manual says to use some sort of interface to send codes to deflate. Isn't there some way to deflate so I can remove the shocks?
There's a scanner signal that sends a code to deflate it. There may be some other way but if you're replaceing it, the scanner is to set the ride height too.
Thanks. I have a computer based program that reads codes, etc, but is not Ford specific and doesn't have the ability to send codes (other than to clear error codes). I was thinking that if I jack the front up (by the frame), thereby making the height sensor think the front was too high, then turning on the suspension switch, the system would bleed air (trying to lower the front), thereby removing air from the front air shocks such that I would be able to remove them. Plausible? Dangerous? Any other ideas?
Also, is the rear air suspension (air spring) independent of the front such that I could remove an air line to a front shock (after somehow bleeding the air) without the rear deflating?
Im having kind of the same problem. I have a 98 ford expedition. Everything is holding air, no leaks. I cant get it to level out. The passenger side always sits higher than the driver's side. I can manipulate the system and I can get all the shocks n bags to deflate except the front passenger shock. Even if I unplug the air line to it, it will still not empty the air out. Can anyone help?
