Although funny it wasn't showing in the error codes when i tried calibration with the et.
From my experience, if you try a calibration using ET, it notifies you directly of an active code (as in, you see a pop-up message on-screen) only if the respective error should negatively impact the result of the calibration you're performing. If it's an unrelated service code, it does not show up by itself; you have to check them yourself - click toolbar on Diagnostics -> Active Diagnostic Codes, or press F3 on the keyboard.
I also love using the clicker box on dozers, even loaders & graders sometimes. On dozers actually, I've become so familiar with it, that I actually prefer using it 90% of the time, rather than connecting the laptop via ET.
