Sometimes diagnostics aren’t necessary to troubleshoot.
Following advice here on the forum I removed the compressor cover and could hear leaking air from one of the brass fittings in the manifold assembly.
I removed all of the fittings & used silicon tape to cover the threads. Tightened everything back up and cycled the suspension. No leaks. No codes.
Thankfully it was something silly.
