The connecting tube for the diff lock/ECU hose to the top of the manifold
was loose.  I just did not notice...

I went through the other diagnostics for nothing, but at least the routine
is getting more familiar.  How is the tube fastened onto the manifold?
Pressure fit only, or can I stick some adhesive in there?

Again, thank you, Phil.
