Others may offer better advice...but I will tell you where I would start.
I am not familiar with the cruise-airs or the SMX controller, but I would start by trying to isolate the components.
On the SCS, there is a wiring diagram inside the cover that covers the wiring. This diagram will show you where the two plugs are that control the compressors. Once you find the compressor wiring...use a clamp on ammeter to figure out what the amp draw is. There are other posts on the forum that will tell you how many amps are normal, but I remember something like 15 on one and 13 on the other.
Understanding the amp draw is the first step to figuring out a breaker issue.
In my case, I had a strange case where the AC wire that fed the SCS unit was shorted somewhere that I could not get to. The solution was to run a new wire back to the breaker box. (This was a very unusual situation but it was easy to find since my units were drawing a normal amount of current before the breaker tripped).
