Thread: Diagnosing air suspension problem

Some more info...
The old compressor that I put back in has now introduced some new symptoms. I am generally getting a suspension fault (normal height only and the orange dash light ) sometime after starting and am unable to raise or lower the suspension after restarting. This would indicate that the compressor is unable to deliver enough pressure to operate the system under any circumstances which is different to the previous symptoms. I'll put the later model compressor back in with the new valve swapped over and report back.
Graeme, It's due for a service so I'll get the codes checked then but with the previous compressor it wasnt logging any permanent codes after restarting. It's an interesting learning experience playing with this stuff.

As an exercise I disconnected the battery overnight and reconnected it. The compressor fired up immediately and the suspension operated normally. The truck is parked at the airport for a week so it will be interesting to see what it's mood is when I pick it up. Haven't had a suspension fault since I reconnected the battery on Sunday Morning. Maybe I scared it by booking it into the stealer to have the compressor looked at next Monday. (or maybe reseating the hoses from the compressor cured a slow leak and disconnectinmg the battery cleared the errors allowing normal operation)
More drama to come I'm sure......
