I'm having the "Suspension Fault - Normal Height Only" error on my 2006 LR3.
I've owned the truck for over a year, and bought it used from the dealer. The air suspension has worked find until early Feb when we got 5-8" of snow in Cincinnati on the day my dad got hurt and I had to go pull him out of a house. (One thing was that the truck, since purchase, has always been on the bump stops after leaving it sit overnight, or while at work, but it always pumped right back up when it was time to leave. I always thought this was normal behavior, but since have found it is not.)
After driving back and forth on the highway to a hospital and then to my house and back, I tried to lower the suspension to help my dad get in the truck and it threw this error. It hasn't gone away since.
According to my IIDTool that I got in early March, I get the following error code.
C1A32 - Front right Corner Valve
Going off that code and reading through the Service manual, I figured it was the valve that was the problem, so I ordered that. Replaced the front valve block over the weekend. Still have the error, still can't raise or lower the suspension without a full system fault that knocks out the Special programs, but the truck no longer sinks overnight, or during the day while it is parked.
One thing I did notice during the valve replacement is that there was some white residue inside the air pipe that feeds the right front corner. It didn't seem like a problem before, but could be an issue. A blockage perhaps? Anyone have a clue what could be the problem?
The battery on the truck was replaced in the fall. The compressor works just fine, so please don't tell me that it is the compressor that is the issue. I did a full system bleed to change the valve and it pumped the system right back up with no issues.
Should I just unplug the battery for a few hours and see if that finally resets everything?
Secondly, if you have not taken your fender trim off, I recommend you do so. I found a ton of leaves inside the fender that had come down from under the hood. Where the struts that hold the hood open mount is a large hole that allows leaves and water to get down inside the fender. Not the best design there...
