If you're trying to do a scan, there must be a reason. Or, are you just trying to learn a bit more about this control?
On the scan, at what point does it fail? The scan window should tell you.
If your having an intermittent fault, run the recorder also in IMS while running the car, and just maybe you'll catch it while you're there. Check the slowdown magnets for any gaps and correct.
Also, post the faults if you're lacking documentation.
DZ and DZE (and magnets gaps) are common selector faults that can be annoying and intermittent.
