Unable to clear error codes

[FastWgn]

I'd guess the actual error is still there. They shouldn't come back otherwise.

Well, the issue is not that the error comes back, rather that Orbit was unable to clear them in the first place. Tried multiple times and the errors were all "stacked", starting with wheel speed sensor out of range and hence many other systems failing. 
But nothing was actually broken, it was just that we had car in gear on lift without placing it in dyno mode. 

Using VIDA I cleared all codes in first try. And never came back of course. 

So, either way there seems to be a situation where you have numerous codes and Orbit is not able to clear them all. Maybe a sequencing issue? Or other dependencies?
